(57) Abstract:

Communication with angular correction in accordance with the proposed invention provides for two modules articulated road vehicle, a front module and the subsequent module, interconnected by means of some self-supporting intermediate module, in relation to which the modules a and b respectively oriented at angles of and , and referred to the intermediate module is pivotally connected with the modules a and b by means of two swivel joints D and E. the above-Mentioned relationship with the angular corrector consists of a slash hard link F, which continues some of the turning device N, managed by means of a drive device with a profiled Cam for providing angular adjustment of the lateral skidding of the vehicle in accordance with some law of angular correction, determining the dependence of the above-mentioned angle of said angle and having some Central area with a slight slope, terminating at each of its ends of some of the transition area. This invention is of interest to designers of road articulated means th="ptx2">

The present invention relates to a connection with the angular adjustment device located between the two mating traffic modules, interconnected can be rotated by means of a self-supporting intermediate module that forms one of the nodes articulated road vehicles.

Ideal properties cornering road vehicles, with articulation and formed by several successive modules or conveyances, ensuring the intermodule swivel in which the law of angular deflection between modules provides a constant orientation of the axes to the center of the rotation.

Vehicles with this property are referred to as vehicles with radial axes.

This property is of interest in relation to urban vehicles, as it allows to do the minimum dynamic allotment of land on the bends.

However, the specified property is insufficient for articulated vehicles with multiple successive modules, one module Zan is, soprovojdayuschiisya more or less pronounced lateral displacement.

Such is the case with road articulated vehicles, each module which is separated from the neighboring via an intermediate module that is installed on the axis and associated with both the adjacent modules by means of the rotary articulated joint having as additional kinematic voltage tough inclined relationship to each module, providing a direct connection between two consecutive modules with communication in the form of a ball joint on each end.

Despite the presence of an inclined rigid links, the behavior of the road, articulated vehicles of this type are characterized by the presence of a fairly serious deficiencies that caused the creation of this invention.

First, in respect of such articulated road systems during their movement in a straight line and when reaching a certain speed there are drifts that reduce the safety of passengers.

Secondly, from a purely kinematic property intermodule articulated links causes deviations in yaw on the exit surface is to be exceeded the permissible limit.

The first disadvantage can be eliminated by blocking the rotary movement of one of the swivel hinges, such as hinge front of the module, ensuring that the configuration of the car + trailer". From the practice known stability of such Association, continuing at the maximum operating speed.

Such blocking mechanically leads to the removal of most areas on steep turns.

However, as mentioned above, when the modern road traffic in the city under the passenger of the vehicle on curves areas shall be a minimum size.

These requirements does not allow us to consider the use of a single specified above reception block one hinge for articulated urban passenger vehicle traffic on curved areas, because it does not provide a guaranteed minimum allocation areas around the route.

The present invention aims at the simultaneous elimination of the above disadvantages of both, namely: loss of resistance when moving in straight upon reaching a certain speed and lateral displacement at the exit of the turn, obespechivayuschikh conditions.

This invention represents an overall improvement of the integral hinge connections between two consecutive modules of the same articulated road vehicle, interconnected intermediate self-supporting, driving or towing module.

This General improvement used in this type of hinge connections between two consecutive modules, front and further separated by an intermediate module, with which each of these modules is connected through a swivel hinge, characterized in that relationship, articulated through the intermediate module and swivel joints, additionally, is connected to the angular correction with low sensitivity with respect to the center on both sides of the direction of the straight line, to control the orientation of the front module based on the orientation of the subsequent module.

Other technical details and advantages of the invention set forth in the description below, given as an example and supplemented by drawings, in which:

- Fig. 1 schematically shows a General view in plan of the hinge connection between two successive modules having functional is I;

The present invention is applicable for articulated road vehicles, consisting of many modules, interconnected by inter-module integral hinge. Such inter-module integral hinge is in principle located between the front module and A subsequent module In a self-supporting intermediate module C, the hinge associated with both modules A and B by means of the hinge, respectively, front D and subsequent E, rotatable around a vertical axis.

The invention is applicable primarily for intermodule integral hinge having advanced gesto articulated road vehicles. The angular relationship of the correction according to the invention, provided between the modules A and B, articulated between an intermediate module C, stems from the General inventive concept, namely, to provide between the front module and A subsequent B communication angular correction, providing the angle between the front module A and the intermediate module C (Fig. 3) in accordance with the law of angular deviation as a function of the angle between the intermediate module C and the subsequent module B (Fig. 3). This law provides for the presence of a Central zone with a small or zero slope at values less than a specified value, this Central zone is characterized by a function of the relationship between angles and in which the effect of wobbling modules significantly reduced.

Everything happens in such a manner as if the composite articulated connection is of the type "car + trailer in a straight line and at small angles, i.e., as if the front hinge D was locked or blocked, determining the presence of a rigid connection between the front and intermediate modules until it reaches a maximum angular value, from which the angle becomes an increasing function of the angle of turn.

According to the design Misharina line D - E is a straight-line segment of constant length "d".

As mentioned above, this type of communication needs at the exit of the curved track sections adapted in angular correction, neutralizing wobbling due to the peculiarity of the intermodule hinge connection used for composite vehicles articulated with the partitioning provided by the present invention.

In General, the correction circuit according to the invention consists of a rigid connection of F, for example, inclined performed between the module and A block representing a correcting device G and changing the angular orientation of A module relative to the module C depending on the orientation of the function module B with respect to the module C

The specified device G is a purely mechanical device, i.e., mechanical control, but it can be controlled through your computer by using the sensor or any other special control system.

Its function is to adjust the position, which would have taken at orientation modules on the bends and, mainly, at the exit from the curved track sections, essieu.

The General schematic of Fig. 1 is intended to emphasize the General nature of the invention.

In General, the device G is the angular adjustment device that changes the characteristics and, in particular, the angular expression of A module relative to the module C, or angle , depending on the control position of module B in relation to module C, or the angle of the curve and on the way out of it. The management team is transmitted through the inclined connection F provided between the front module and A device G or sensor angular deviation or by any other means intended to convey information about the size of an angle .

This information is provided through an inclined rigid links F, connecting the front module and A device G, which is in accordance with a special embodiment is made in the form of thrust, the ends of which are pivotally connected to each of said devices.

The correcting device G consists of two blocks: deflecting device H and the drive device I, interacting with each other.

The deflecting device H is pivotally connected with the front module through A communication F, which provides a mechanical transmission to the specified Mor> Drive unit 1 is rigidly connected with the subsequent module B. It sets the law of angular correction and acts articulated connection of the angular correction of the drive with corner trim, providing the change of the angle and the maximum neutralization of Vilani at the exit of the turns due to the law of angular compliance of the Central zone with a low sensitivity to small angular values turn both right and left.

Compound hinge module-to-module communication is characterized by two modes of operation depending on the value of the angle when moving along the curve:

- car + trailer" for small values of the angles of deflection of the subsequent module B with respect to module C, i.e., the angle , the mode in which the rotary motion of the intermediate module C with respect to the front module A corresponding to the corner , almost neutralized by small values of the angle , while the movement of the subsequent module B remain free with respect to the intermediate module C;

mode, asked for larger angles of deflection of the subsequent module B with respect to the intermediate module C, a mode in which the rotary motion of the intermediate module C with respect regime to another occurs in the transition zone, located at the end of the Central zone, as shown in Fig. 15.

Consider now the invention from the point of view of its special funds, using a detailed description of several mechanical options.

Refer primarily to figures 2, 4 and 5.

The correction circuit includes, in General, first of all, the inclined hinge connection F designed for the transfer of team orientation, pivotally mounted between the front point J swivel, fixed on the housing front module A, and the point K swivel fixed on the deflecting device H, rotating around a vertical axis L located at the intermediate module C, secant axis, to ensure symmetry, together with the line connecting the hinges D and E.

The deflecting device H is an oscillating articulated joint connected to the inclined connection between F and in contact with the drive unit 1 by means of at least one element that moves along the guide.

Here we can talk primarily about turning around the axis L of the element 1, made in the form of a triangle, the base of which are the tools with her reference to the contact points M and N of the profile 5 of the governing body 6, rigidly mounted on the chassis module B, acting on the means of rolling (Fig. 5).

The deflecting device H can also be done in the form of a hinge connected to node 7, which is a simple rod, rotating around the axis of the roller L, one end of which is articulated to the end K of the inclined gear thrust F and the other end carries a means of bearings, such as roller 9. Auxiliary rod 10 that is installed with the possibility of rotation around the axis L, complements the relationship between the axis of the roller L and the second rolling tool, made in the form of roller 11. The rollers 9 and 11 are also in abutment contact points M and N with edge profile 5 of the governing body 6.

In order to prevent hypercriticism characteristic of this thrust interconnected by means of a spring 12, as shown in Fig. 2, providing a permanent contact of the rollers.

Drive unit 1 has variants, representing the Cam 13 or the guide 14, the housings are rigidly connected with the subsequent module (Fig. 2, 4, 5, 6).

General identical form of technical execution profile of the Cam 5 may be different depending on its position on maclennane with two rollers has a common, substantially symmetrical profile 5 formed by two halves 15 and 16. The Central part 17 of the specified profile has a Central V-shaped. more or less pronounced deepening 18, more or less extended. Each half 15 and 16 has consistently located towards each end of the Cam 13 upward part 19 and 20, the section of the ring curves 21, 22, land Assembly 23, 24 corresponding form, for example, in the form of a Cup-shaped recess, the convexity of which is oriented in the same direction as the Central bulge of the recesses 18, or inclined section 27, 28, as shown in Fig. 8 and 9.

Each of the sections of the ring curves 21, 22 located on the left and right, made in the form of an arc of a circle 29 and 30. These circular arcs are the same and have its center the center of the hinge that is, These areas are shown in Fig. 2 solid line and every time materialize in the form of arrows.

The shape of the Cam profile may vary depending on achieved private law.

It will vary from one intermodule communication to another on the same dump truck while maintaining the same General shape. Indeed, due to the related cooperation is Ofili Cams or their mechanical equivalents will vary among themselves, as can be seen in Fig. 7, 8 and 9, which shows the options for the form of the Cam profile.

A variant is shown in Fig. 6 is a functional equivalent of Cam mechanisms. According to this variant deflecting device H is made in the form of a plate 31 that is rotatable around a vertical axis L, intersecting at site 32 with the line D - E under the action of a drive device I.

This plate at its free end carries a transverse, located perpendicular to its plane element, for example, witness the finger 33, the end of the axis, or any other similar tool, capable of moving along the guide. In this case, the drive device 1 acts as a guide means, for example, the guide being made in the form of slots 34, along which moves the witness finger 33. The slot 34 is made in a horizontal plate rigidly mounted on the chassis of the subsequent module Century Form specified slot corresponds generally to the shape of the Cam profile 5 on one of the substantially symmetric halves 15, 16, for example, on the left.

Here are one of the slope 35 of the Central recess 18 and the annular area 36 in the form of control is the goal , formed hard megamini swivel connection D-E and the axis of the front module A. the Angle defined as the angle between megamini rigid rotary connection D-E and axis subsequent module Century

Angles and correspond to the slopes, present respectively between the front module and A intermediate C, and between the latter and the subsequent module Century In this form they are shown also in Fig. 3.

According to the invention the angle is a function of the angle , namely:

= 0 or small progressive value, when 1 2; = f(), when 2 or 1

mostly when 1 = 2 in absolute value.

Thus, the function has a plot or Central zone 38 with a zero or small value and small slope in areas characterized by both magnitude and 2 (Fig. 15), and at each of these ends has a transition zone 39 and 40.

Mechanical site formed by the inclined thrust F, the deflecting device H and I drive allows you to perform a specified act, the limit value which exceeds values of 1 and 2, and the angular function is determined by the Cam profile.

To achieve this goal, the Cam is substantially symmetrical public profile, as described above, and the TLD is Noah halves (Fig. 6).

From this figure it is easy to understand that the initial movement of the push / pull thrust F, i.e., the movement corresponding to the initial degree angle will not change or will change in a very small degree angle . In this case, movement of the angular deviations are similar to the movements of the type "car + trailer, in which the modules A and C act as a vehicle, and a module - as the trailer.

In fact, an entire section of the Cam profile having a circular curvature in the form of an arc of a circle with its center coincident with the center of rotation of the hinge E, which is partly shown by triclinia, rotation will be transmitted by the rolling of the rollers at the points M and N on the segment of a circle, whose center coincides with the center of rotation of the subsequent module, i.e., the center of the swivel is, With a more pronounced inclination of the pair of rollers will deviate even more, of which one roller reaches the end sections of the Cam profile, and the other slope of the Central recess, resulting in a change of angle in accordance with the desired law (Fig. 10-14).

A variant is shown in Fig. 6, has a circular section of the slot, corresponding to small values of angles in the case of AB is m track does not have a significant impact on changing the orientation of the front module A with respect to the intermediate C. Thus, the team is neutralized with a small angular amplitude, directly dependent on the length made in the form of arcs of a circle sections of the Cam profile. Everything happens in such a way as if the pivot point D was blocked.

When the angle increases, the Cam mechanism causes a change in the regime. The rollers extend beyond the section of the ring radii and move around the portion of the track profile, which changes the angle and the magnitude is dependent on values in accordance with the law, to limit the amount of lateral wobbling at the exit of the curved sections.

According to the developed variant oblique thrust can be used to provide another mode of operation that is beyond the scope of this invention. In this case we are talking about deadlift for use in two appointments, the first appointment thrust maintains constant length and is used in conjunction with correcting device according to the invention, and in the second assignment the variable length of the rod, and the rig is controlled by other means without the use of angular adjustment device.
