(57) Abstract:

Usage: the invention relates to a transport machine-building, namely the coupling devices trackless articulated vehicles, and is intended to be coupled between a single thacham and double trailer. The inventive coupling device comprises a rigidly fixed on each link brackets 1 and 2,which are interconnected by means of brackets 5 and 7 and the coupling element with 3 horizontal and 4 vertical fingers. Between the lugs of the bracket 7 is placed a mechanism to enforce bending a single truck when cornering and stability of the truck when driving in a straight line and in the Parking lot. This mechanism made according to the invention in two ways. One when driving in a straight line and in the Parking lot of a horizontal rod locks the specified mechanism, preventing the inclination of the vertical axis, and cornering forces specified axis, together with a single tractor to lean in the direction of rotation. In another embodiment, the specified mechanism is in the form of two toothed sectors. 2 S. and 2 C.p. f-crystals, 6 ill.

The invention relates to transport machinery, namely, the towing device is thacham and double trailer.

Known hitch articulated vehicle (USSR and. C. N 1705134, IPC B 60 D 1/00, 1989) containing installed on each level of the vehicle brackets, which are interconnected via a connecting element and hinge with horizontal and vertical axes, the axes of which are placed in the same plane, with horizontal and vertical axes located in the same plane, two thrust along the longitudinal axis of the connection element, and so on and so on

However, this coupling is structurally difficult in itself, and is intended for articulation of the links of the dual-track vehicles, because these units are independent of one another while bending their transverse axes.

Known hitch articulated vehicle (USSR and. C. N1713837, IPC B 60 D 1/00, 1989) containing each element of the vehicle brackets, which are interconnected via a connecting element and hinges from the horizontal and vertical axes located in the same transverse plane, the connecting element associated with their ends with the brackets of each link by hinges from the horizontal and vertical axes, and in intalnim element, and other ends pivotally connected with the bracket of one of the parts of the vehicle.

But this hitch has a complex structure. It is designed for coupling two vehicles and unacceptable for coupling vehicles, in which at least only a single tractor, for example, for articulation motorcycle or Bicycle with double-trailer truck, because it is not equipped with a mechanism to enforce tilt-track transport truck, regardless of the trailer when driving in curves and its stability when driving in a straight line or in the Parking lot. In the absence of cornering lateral tilt it may not have good stability, flexibility and working conditions of the driver, because it does not exclude the possibility of overturning the tractor or throwing the driver from his seat. Reliable stability in the vertical plane straight-line it can be only if there are hard links of the tractor-trailer in a specified plane or lateral supporting elements.

The closest analogue of the claimed invention is a technical solution for U.S. patent N 4261592, IPC 60 D 1/14, 1981 Known ro technical means, two brackets with lugs at their ends, with the first bracket rigidly mounted on a bracket on the tractor and is located horizontally, and a second bracket mounted on the bracket of the trailer can be rotated about the longitudinal axis of the bracket and disposed vertically, the connecting element with four fingers, covered by the lugs of the first and second brackets. This solution can be used to capture a single tractor with double trailer, but it has no mechanism to enforce tilt of the tractor regardless of the trailer.

The aim of the invention is to provide an articulated coupling between a single Prime mover, such as a motorcycle or Bicycle, and double-trailer, for example, double-track trolley having a transverse axle for the wheels. This would give the opportunity to improve the maneuverability of the vehicle, the working conditions of the driver and the safety while driving due to the forced lateral tilting of the tractor when driving in turns while ensuring rigid in the vertical plane of the tractor-trailer when driving in a straight line and in the Parking lot.

The objective is achieved as follows.

Coupling from the rigidly attached to each link of the vehicle brackets (one on each of the links), interconnected via a connecting element with four cylindrical fingers rigidly interconnected and arranged in one transverse relative to the longitudinal axis of the vehicle plane. Each bracket rigidly one end connected to one of the parts of the vehicle, and the other end of the bracket, which is made with eyelets. The first bracket rigidly mounted on a bracket on the tractor, and a second bracket mounted on the bracket of the trailer can be rotated about the longitudinal axis of the bracket and disposed vertically. On the second bracket between its eyes posted mechanism to enforce tilt of the tractor regardless of the trailer. The mechanism includes a vertical guide sleeve from longitudinal slits in the front and rear walls of glass, inside of which, with the possibility of sliding along and around the axis of the Cup is placed a cylindrical spool with cross-drilled, through which it is slidable, and free passage through the slit glass skipped horizontal rod fixed on the top of a vertically placed finger jointing element.

In the second embodiment, the design is otceplennyj sectors bevel gears, one of which is rigidly fixed on the top of the end bracket of the trailer, and the second is rigidly attached to the top of the vertically oriented fingers of the connecting element.

In all cases, the connecting element may be in the form of two cylindrical rods, upright of which has a thickness in the middle part. This thickening made a hole to accommodate with the possibility of fixation of the horizontal cylindrical rod.

In Fig.1-3 are views in partial sections of the coupling device with the mechanism of forced bending and stability of the tractor, comprising a vertical guide Cup, the spool and horizontal finger, Fig. 4-6 hitch with the specified mechanism containing gear sector.

Hitch articulated vehicle, a Prime mover which single and double trailer contains rigidly mounted on each link of the vehicle, the brackets 1 and 2 (one on each of the links), which are interconnected via a connecting element with a horizontally and vertically spaced fingers 3 and 4 are rigidly interconnected and positioned in one Eniro connected to the bracket 1 of the Prime mover by means of the bracket 5 with the lugs 6, rigidly mounted on the specified mount bracket, and a vertical finger 4, hinged to the bracket 2 of the trailer by means of brackets 7 with lugs 8, rigidly secured to the sleeve 9 mounted on a bracket on the trailer with the possibility of rotation around the longitudinal horizontal axis of the specified bracket. On the top of the bracket in the space between the lugs of the bracket posted mechanism to enforce the lateral tilting of the tractor regardless of the trailer when motion cornering and stability of the tractor in a vertical plane when moving in a straight line and in the Parking lot, with vertical guide glass 10 with longitudinal slots 11 in the front and rear walls of glass. Inside the jar with the possibility of sliding along and around the axis of the Cup is placed a cylindrical spool 12 with cross-drilled, through which it is slidable, and free passage through the slit glass skipped horizontal rod 13 fixed on the upper, vertically placed finger jointing element.

In the second variant of the design of the coupling mechanism of forced bending and stability of the truck is made in the form of two vzaimozachetnykh gear sectorielle attached to the top, vertically located finger jointing element.

The connecting element may be in the form of two cylindrical rods 16 and 17, the upright of which is in the middle part of the thickening, which made the hole to accommodate with the possibility of fixation of the horizontal cylindrical rod.

Hitch works as follows.

Deviations of the longitudinal axes of the links of the articulated vehicle at some angle relative to each other in the horizontal plane, i.e., when turning, is provided by swivel on the vertical axis of the connecting element, and the deviation in the vertical plane, i.e., when driving on a surface with a variable bias due to the same connections on the horizontal axis. When driving in a straight line or in the Parking lot of the transverse axis of the links of the articulated vehicle held in a position parallel to each other because the rod 13 passes through the cracks in the glass 10, fixed to the bracket 2 trailer, and the opening of the valve 12 installed in the glass. The longitudinal axis of the articulated links appear to be bounded from povorachivanie horizontale spaced fingers placed in the lugs 6 of the bracket 5, rigidly mounted on the bracket 1 of the Prime mover, the rod 13 is rigidly secured to a vertically located the finger 4, and the glass 10 is rigidly fixed to the bracket 2 trailer.

When driving in turns longitudinal axis of the tractor deviates in the horizontal plane at some angle from the longitudinal axis of the trailer and rotates the finger (4) around its axis. Meanwhile the glass (10) remains stationary, since the double trailer is not rotated around its longitudinal axis, and the free end of the rod (13), pushing through the valve (10) in the side walls of the Cup and rotatable in a horizontal plane, tilts her at some angle from vertical in the direction of rotation of the Prime mover, which is possible because the vertical fingers mounted in the lugs (8) bracket 7 fixed on the sleeve 9 mounted on a bracket on the trailer with the possibility of rotation around its longitudinal axis, and a rod freely slides through the hole of the spool, as the spool is moved along the glass. As a result of this interaction of these elements provides the required lateral tilt single tractor when driving in curves and at the same time of Baklanov tractor, containing relevant sectors 14 and 15, works in a similar way with the only difference that the inclination of the vertical axis is achieved by rolling sector 15 on a stationary sector 14 as it rotates together with the vertically spaced fingers of the connecting element.

The implementation of the coupling element of the two rods allows quick attachment of parts of the vehicle, thereby improving the operating conditions of the coupling device, and the possibility of removing the horizontal rod 13 allows the use of this coupling device for coupling two parts.
