The invention relates to a forced steering system, according to the restrictive part of paragraph 1 of the claims.

When this vehicle is used as the Prime mover is a motor vehicle and trailer - non-powered vehicle, made in the form of a combination of vehicles articulated vehicles.

To ensure the sustainability of the movement of non-motorized vehicles, particularly trailers, with the help of a tractor, in particular a tractor, and improved agility consisting of a trailer and towing vehicle combination of vehicles used in the system of forced control.

System of coercive control are used in vehicles with multiple rear axles and serve to steer at least one steerable rear axle. These systems force control has the task of deviation of one of the rear axles of the trailer depending on the position of the tractor relative to the trailer. It offers the advantage that when cornering the tractor and trailer lying one behind the other wheel several rear axles, in particular all of the axles of the trailer, at least essentially roll in the same gauge.

However, a disadvantage is that when using a trailer with ex is different tractor, for example, when the standard tractor is maintenance, repair, modified and/or replaced, the system of forced control no longer works correctly and lying one behind the other wheel several rear axles, in particular all of the axles of the trailer, when driving in turns to roll without keeping track.

Therefore, the object of the invention is the creation of a system of coercive control is specified at the beginning of the form, which you can use to prevent these drawbacks, and which at many different tractors provides the possibility of rolling, lying one behind the other wheels several rear axles of the trailer when driving in turns with lateral stability (keeping track).

This is achieved according to the invention, using the characteristics of paragraph 1 of the claims.

This provides the advantage that different coupling parts can be used for many different tractors. Many of these coupling parts for each of the many tractors can be pre-assigned to one coupling part.

While it is preferable that each trailer and each truck is provided by the possibility of a predefined assignment of suitable coupling parts. While it is preferable that after the selection of a suitable coupling part of the process of coupling can be performed in a normal Abrazame thereby no additional cost or with only a small additional cost in order lying behind each other of the several wheels of the rear axles of the trailer when the cornering forces rolled into one track. In addition, the invention does not complicate the region of the coupling through the use of numerous transition elements between a tractor and a trailer and does not increase at the expense of located at an altitude of successive elements, the vertical dimensions of the specified area, which could lead to a reduction in ground clearance.

The invention relates also to a method of connecting the system force control according to the restrictive part of paragraph 8 of the claims.

In accordance with this objective of the invention is to provide such a method which can be prevented by the above disadvantages and which in many different tractors provides the possibility of rolling, lying one behind the other wheels several rear axles of the trailer when driving in turns to hold the gauge at least essentially in the same gauge.

This problem is solved according to the invention by the characteristics of paragraph 8 of the claims. Due to this, provided the above listed advantages and preferred effects.

Dependent claims that as well as paragraphs 1 and 8 simultaneously form part of the description, refer to another preferred options done the ment of the invention.

In a preferred modification can be provided by the featured item 2 claims. Due to this can be prevented rotation of the Prime mover at a predetermined angle between the tractor and the drawbar. While it is preferable that the expense of this can be set to the maximum angle between the tractor and the drawbar, it may be set to a maximum deviation of forced control, and thus can be ensured that the system of forced control is not rejected for the maximum critical angle.

Below is a more detailed description of the invention based on the above only as an example of preferred embodiments with reference to the accompanying drawings, which schematically:

figure 5 - part of the hydraulic circuit in the area of the second hydraulic cylinder systems force control according to a third preferred variant of execution, and the place of the tie rod is provided with two second hydraulic cylinder; and

Figure 1-6 shows at least part of the system 1 positive control for applying at least one trailer 4 and several different tractors 5, containing at least one coupling part 2 for the location on the tractor is 5 and the coupling loop part 3 for the location of the trailer 4, when this coupling part 2 and the coupling loop portion 3 designed for coupling with each other at the point 11 of the clutch and located at a distance from a point 11 of the coupling point 12 swivel, for which it is proposed that each of these many different tractors 5 using at least one of the aforementioned at least the coupling portion 2 provided with point 11 of the clutch and the 12 point swivel, respectively, at a given distance from the rear axle 51 of the tractor 5.

Figures 1 and 2 schematically shows the Prime mover 5 and made in the form of trailer 4 non-motorized vehicle, the Prime mover 5 and the trailer 4 form is made in the form of a combination of vehicles lorry.

1 force control can be applied, in particular, the connection system 1 positive control to force control at least one wheel 41 of the trailer 4, which may alternately be towed different tractors 5. The method includes the steps:

- the location of one of the pre-defined coupling parts 2 on the carrier 5 to the location of the point 11 of the clutch and 12 point swivel at specified distance to the rear axle 51 of the tractor 5, depending on the mentioned relevant from a variety of tractors 5, and

- coupling with each other, the coupling is Oh hinge part 3 located on the trailer 4, with a corresponding coupling part 2 in point 11 of the clutch and located at a distance from a point 11 of the coupling point 12 swivel.

System 1 positive control and the method of connection, in particular, the system 1 positive control, provide the above advantages and preferred effects. In particular, the system 1 positive control and a way to force management to provide rolling at least essentially in the same gauge adjacent wheels 41 multiple rear axles 42 even when different tractors 5.

System 1 force control is applied when towing vehicles with multiple rear axles 42 and serve to steer at least one steerable rear axle 44, which in contrast is not steered rear axles are made with management. Control in this context means that the position mounted on a managed rear axle 44 wheels 41 can take a set of different inclination angles, the management of the wheels 41 may be called the deflection wheel 41.

The advantage of the system 1 forced control is that when the system 1 forced trailer control 4 agreed with the Prime mover 5, Li is the following one behind the other wheel 41 multiple rear axles 42, preferably all of the axles of the trailer 4, not only when driving in a straight line, as schematically shown in figure 1, but also when driving in rotation, as schematically shown in figure 2, roll in the same gauge. It is preferred, in particular, when moving across the field, arable land, field road and/or forest road, because lying one behind the other wheel 41 of the trailer 4 also when driving in turn create essentially only a single track. Because while the crop fields and/or arable land not crushed, the crop does not suffer. It is also less compacted soil surface of the field and/or arable land, which forced control preferably also for soil conservation. Finally, you can safely move on the narrow and difficult passable field roads and/or forest roads, because the trailer should be used with great accuracy in the track of the tractor 5 by 1 force control.

However, problematic for system 1 steer is the change of the Prime mover 5. Since different tractors 5, based on the different distances between the front axle 53 and the rear axle 51 of the tractor 5 and on the basis of a variety of track widths, i.e. the distance between the wheels on the axle, have different characteristics deviation, it is necessary for the optimum and proper follow trailer 4, coordinate system 1 positive control with sootvetstvuyuschim used as the Prime mover of the vehicle 5. This agreement contains the angular dependence and direct position (straight-ahead) system 1 positive control, which is necessary to agree on every possible combination of vehicles, i.e. the specified trailer 4 and set the tractor 5 individually depending on the angle and in the direct provision system 1 positive control.

The direct provision system 1 forced control is usually set by setting a combination of vehicles, i.e. the trailer 4 and the corresponding truck 5 on a flat surface and compounds as coupling loop 35, and the control loop 36 on the carrier 5. To do this, open the control valves of the control unit 64 and installing 1 forced control on follow mode. Follow mode 1 push the control means is usually provided by the hydraulic system 6, the connection switches to the lack of transmission of force, and thereby driven rear axle 44 of the trailer 4 instead of forcing management is enabled in the mode of government, in particular, the following. When driving in a straight driven rear axle 44 of the trailer also moves right. After switching system 1 forced control forced control, i.e. after changing the connection mode in which the transmission of force agree on a position of the first hydraulic cylinder 61 and the second hydraulic cylinder 62 for combination vehicles.

The first hydraulic cylinder 61 and/or the second hydraulic cylinder 62 can be preferably double-acting cylinders.

The first hydraulic cylinder 61 can preferably be made as a master cylinder, thus changing the position of the first hydraulic cylinder 61 is converted into the movement of hydraulic fluid. The second hydraulic cylinder 62 can preferably be made as the slave cylinder, with controlled master cylinder, the movement of hydraulic fluid causes a change in the position of the slave cylinder.

For filling and installation working pressure of hydraulic fluid in the system 1 of coercive control, which is preferably between 50 bar and 100 bar, i.e. preferably between 5 MPa and 10 MPa, the hydraulic system 6 may preferably contain hand pump 67.

In follow mode, ie, in particular, in the mode of propulsion, system 1 forced control is usually not optimum adherence, ie, in particular, exactly in the track of the trailer 4 for the Prime mover 5, therefore, during normal operation of combination vehicles predpochtite the d is the so-called forced control 1 positive control.

Preferably, the hydraulic system 6 may include a ball valve to switch between distance and mode of forced control 1 positive control. This is especially easy to switch the operating condition 1 forced control mode force control mode sequence, and Vice versa. While it is preferable that at each position, respectively, in each situation, combination of vehicles, you can switch the operating state of the system 1 forced control mode force control mode sequence, this can be unloaded control system of the tractor 5. It is also preferable that when the tractor is not 12 point swivel, you can simply switch the operating state of the system 1 forced control mode force control mode of transportation. Due to this failure of the Prime mover 5, you can tow a trailer 4 with another is made as the towing vehicle towing vehicle 5, thus preferably you can also use a towing vehicle with a coupling point without swivel.

Approval depending on the angle, i.e. the angular relationship between the tractor 5 and the coupling loop 3 otnositel the angle control driven wheels 41 of the trailer 4, system 1 forced control is difficult and often impossible under normal coupling of the trailer as per the changed angular relations are often impossible to change the characteristics of repetition trailer with conventional systems 1 positive control.

Due to this driven wheel 41 on a managed rear axle 44 when not coherent combination of vehicles not deviate from the optimum angle. This often leads to the fact that the trailer is in motion in the rotation should not optimal in a rut. This may limit the maneuverability of combinations of vehicles (lorry), and may cause additional field and/or on the arable land to additional crushing the crop and/or additional soil compaction. The system 1 positive control may deviate for the maximum angle, so that the system 1 positive control may be damaged. All this can lead in the aggregate to the fact that some combination of vehicles may not move in the mode of forced control 1 positive control.

To prevent these disadvantages, in one preferred embodiment, the system 1 positive control provided that on each of the many different tractors 5 with Myung is our least one coupling part 2 is the point 11 of the clutch and the 12 point swivel at specified distance from the rear axle 51 of the tractor 5. This ensures a specified agreement on the optimal angular dependence between the Prime mover 5 and the coupling loop part 3 with respect to the deflection angle of the steered wheels 41 of the trailer 4 for many different combinations of vehicles. While it is preferable that the coordination ratio, which follows from all geometric and defined relations can be calculated and/or determined by the computing device.

Due to this, it is possible for each trailer 4 pre-determine for various, in particular, offer for sale tractors 5 different coupling part 2 and/or to give their trailer 4.

Due to this, you can also for each Prime mover 5 pre-determine for various, in particular, offer for sale trailers 4, various coupling part 2 and/or to give their tractor 5.

In this case, when replacing the tractor 5 with the same trailer 4 can only be mounted on the tractor 5 consistent with this tractor 5 coupling part 2 and possibly to set straight-system 1 positive control, as mentioned above, thereby reducing costs when connecting the trailer 4 and is provided with lateral stability and maneuverability of the trailer 4. Through a suitable choice of the coupling part 2, in particular, when replacing the first Prime mover 5 other than the t he second Prime mover 5, to provide a point 11 of the clutch and the 12 point swivel on the second Prime mover 5 so that there is no need for additional system configuration 1 positive control relative movement in a straight line and the deviation of the steered wheels 41. Additional costs when attaching a trailer 4 is particularly small, with the approval of the characteristics of repetition trailer 4 essentially is due to the choice of this combination of vehicles, i.e. agreed with this combination of trailer 4 and the second Prime mover 5 coupling part 2.

The connection of the first hydraulic cylinder 61 with the coupling part 2 schematically shows, in particular, figure 3, which shows essentially only the first hydraulic cylinder 61 and the coupling part 2. In addition, figure 3 shows the point 11 of the clutch, 12 point swivel, the first hitch ball 22, the second hitch ball 22 and a longitudinal tie rod 33, which contains the first hydraulic cylinder 61. Coupling the hinge part 3 schematically shows, in particular, figure 6. This coupling loop portion 3 can be performed essentially in the form of a drawbar 31 and contain longitudinal steering rod 33. Coupling the hinge part 3 contains a coupling loop 35 to transfer tractive forces from the coupling part, in particular from the point 11 of the coupling on the trailer, and longitudinal tie rod end 33 contains the control pet is th 36 to transmit control forces from the coupling part 2, in particular, from a point 12 swivel, 1 forced control.

Preferably, many combinations of vehicles, i.e. many combinations of different 5 tractors and/or trailers 4, which have similar characteristics repetition trailer 4, can be reduced in several possible classes depending on the coupling part, and the number of classes on the coupling part can be specified. Due to this, it is possible to minimize the number of used different coupling parts 2, so can be reduced manufacturing costs and, in particular, warehousing coupling parts the user.

Preferably, it may be provided that each of the many different tractors 5 agreed spacer kit (support distance elements) 32 for mounting to the trailer 4, preferably on the shaft 31 and/or coupling the hinge portion 3, and the spacer 32 is provided for contact with the tire 52 of the tractor 5 when asked angle between the Prime mover 5 and the trailer 4. Due to this, it is possible to prevent the deviation of the system 1 positive control for maximum angle so that the bending angle from the Prime mover 5 to 4 trailer, in particular, relative to the coupling loop portion 3, preferably relative to the drawbar 31, may be limited. The bending angle, which corresponds to the angle between the thrust is Ohm 5 and 4 trailer, and which is measured between the longitudinal middle axis 55 of the Prime mover 5 and passing through the coupling loop portion 3 of the longitudinal middle axis 38 coupling the hinge part 3, when driving combination vehicles in a straight line, as shown in figure 1, is 0 and may be under the control of the Prime mover 5, as shown in figure 2, up to 90.

Preferably, the maximum bending angle can be set using a set of spacers 32 as in case of deviation to the left, and when the deviation is to the right of the tractor 5 to 45-60, with this kind of limitation of the angle of bend is shown in Fig.6. While it is preferable that the maximum bending angle corresponds corner of the bend between the Prime mover 5 and the trailer 4, wherein the bus 52 of the rear axle 51 of the tractor 5 come in contact with the spacers 32. Preferably, when the contact is created noise and signaled the maximum bending angle, thus coupling the hinge part 3, the shaft 31 and/or bus 52 of the tractor 5 is not damaged.

For this purpose, the spacer 32 may be made of several parts and to hold the lower part of the spacers 321 and the upper portion 322 of the spacer. Due to this, the lower part of the spacers 321 may be made to harmonize the maximum passage of the struts 32 of the coupling hinge part 3, in particular from the drawbar 31 and the upper portion 322 of the spacer to create a noise.

Thus the bottom part 321 spacers can be done is to essentially in the form of a rectangular parallelepiped, and in particular, essentially from sheet metal.

The upper portion 322 of the spacer can be made essentially semi-circular, curved or in the form of jumpers and, in particular, essentially made of plastic, in particular elastomer and/or thermoplastic.

The upper portion 322 of the spacer can be connected Rethimno attachment device on the lower part 321 of the spacer. Due to this, it is possible to connect different bottom spacers 321 and various upper portion 322 of the spacer, which from the few different lower spacers 321 and a few different tops 322 spacers you can create a lot of spacers 32 different geometry and different create noise at the contact of the tire 52 and spacers 32.

Preferably it can be provided that at least one coupling part 2 has in point 11 of the first clutch coupling the ball 21 and the point 12 swivel - second hitch ball 22, when the hitch 4 tractor truck 5 at least one coupling part 2 is connected at the point 11 of coupling with the first coupling ball 21, and in 12 point swivel - with a second hitch ball 22. Due to this, you can just run the hitch 4 tractor truck 5, and can reliably be thrust force transmission, and the transmission control forces.

Coupling loop 35 and the control loop 36 can bitmapname, as shown in Fig.6, in the form Polukarov bowls in the shape of the through-bowl coupling loop and bowl control loops for donning to the first coupling polychar 21 and/or the second coupling polular 22.

In a preferred modification can be provided that the coupling hinge part 3 is intended to connect the 12 point swivel longitudinal steering rod 33, and that the longitudinal tie rod end 33 includes the first hydraulic cylinder 61. Due to this, you can chain coupling loop portion 3 with the longitudinal steering draught 33 in 12 point swivel and connect the first hydraulic cylinder 61 by means of longitudinal tie rod 33 with 12 point swivel. While it is preferable that the usual system of coercive control can also be used with the coupling part 2, in particular with different coupling parts 2, thereby it is possible to ensure correct operation located on the side of the trailer part of the system 1 positive control without changes, in particular without modification.

Preferably it can be provided that at least one calling directly the deviation of the at least one wheel 41 of the trailer 4 the second hydraulic cylinder 62 is connected with a pipeline system 63 with the first hydraulic cylinder 61. In this regard, the principles of the performance management deviation calling directly the deviation of the at least one wheel 41 of the trailer 4 of the second hydraulic cylinder 62 can be performed by using the first hydraulic cylinder 61. This occurs preferably in the mode of forced control 1 positive control, while the first hydraulic cylinder 61 is mechanically connected to the 12 point swivel, the first hydraulic cylinder 61 is connected hydraulically with the second hydraulic cylinder 62 and the second hydraulic cylinder 62 is connected mechanically driven wheels 41 controlled rear axle 44.

In particular, it may be provided that the second hydraulic cylinder 62 is engaged with the lateral steering thrust 7 trailer, with the help of a second hydraulic cylinder 62 can be forced to control the position of the tie rod 7 of the trailer. Due to this, you can use only one of the second hydraulic cylinder 62 to control the deflection angle of both driven wheels 41 controlled rear axle 44. This preferred embodiment of the system 1 force control shown in figures 1, 2 and 4.

In another preferred embodiment, instead of one of the second hydraulic cylinder 62 and rod end 7 of the trailer 4 may be provided two second hydraulic cylinder 62, as shown in figure 5. While located on the side of the wheels, the ends 45 of both hydraulic cylinders 62 is essentially directly connected to the managed what olesome 41, what you can refuse the execution of the tie rod 7.

It may be provided that the pressure peaks in the pipe system 63 in the area of the first hydraulic cylinder 61 are aligned with the first device 65 pressure equalization and/or in the area of the second hydraulic cylinder 62 through the second device 66 pressure equalization.

While it is preferable that the shock and/or excessive pressure in the first hydraulic cylinder 61, which may occur when driving, particularly when driving on uneven ground, are transmitted, in particular, with the weakening of the second hydraulic cylinder 61 and/or the piping system 63. Due to this, you can prevent and/or reduce voltage peaks in the mechanical parts and/or hydraulic fluid pipeline system 63, the second hydraulic cylinder 62 and/or in particular, in a controlled rear axle 44, containing the steered wheels, and possibly the tie rod 7. While it is preferable that may be secured long term service and/or the festival of the cost of forced control.

The first device 65 pressure equalization and/or the second device 66 pressure equalization can be performed in the form of a battery pack pressure 80 bar and/or in the form of a battery pressure 50 bar. The battery pressure 80 bar can align excessive pressure arising from too much bending angle, for example, when the tractor 5 pulls the trailer 4 sets of spacers 32 and, accordingly, strongly rejected.
