Anchor hitch trailer

 

The invention relates to the field of trackless vehicles. Anchor hitch trailer includes a support plate fixed on the frame of the towing vehicle with a saddle and Rethimno-coupling mechanism is connected with a pin rigidly mounted on the supporting sheet of the ledge of the frame of the trailer. The bolt in the support sheet of the ledge of the frame of the semitrailer mounted movably with the possibility of angular rotations about its longitudinal axis of symmetry and translational movement relative to the longitudinal axis of the mentioned frame. The king pin is provided on one side of the two shoulders of the lever carries two spring-loaded by a compression spring thrust, pivotally connected to the finger rigidly mounted on the supporting sheet of the ledge, and on the other gear that interacts with a toothed sleeve rigidly mounted on the saddle anchor hitch of the towing vehicle. The technical result - the efficiency of trains, increasing capacity, reducing the cost of transportation. 3 Il.

The invention relates to the field of trackless vehicles and can be used in the construction of semi auto the other, mounted with semi-trailers models MAZ-5245, MAZ-G, etc. described in the book (M. M. Shchukin. Hitch cars and trucks. - M: motor cycle", 1961 (pages 49-51, Fig.43) and the book (M. S. Vysotsky and other Automobile and tractor trailers. - M: motor cycle", 1962 (pages 80-99, Fig.55)). Such anchor hitch consist of truck devices mounted on the frame of the towing vehicle, are interconnected by pin over the ledge of the frame with the trailer. A significant drawback of such devices is that due to the lack of opportunity for some relative movement of the trailer and the towing vehicle in their longitudinal plane relative to each other at the time of shunting trains, in practice, when designing trains between the end part of the trailer and the cab of the towing vehicle leave a significant gap (from 1.0 to 1.5 m and sometimes more), called "dead" space. This name is confirmed by the fact that this space affects the underutilization of capacity of trains, and this significantly affects its technical and economic indicators.

Also known reference hitch truck ZIL-V, Kama and other aggregated with polupritsepa the ORT, 1983 (see pages 75-82 and pages 89-92)). The construction of the support-coupling devices of these trains similar to those described above and therefore, the shortcomings of their kind.

Therefore, the aim of the invention is to increase the efficiency of the combination.

This objective is achieved in that the pin in the support sheet of the ledge of the frame of the semitrailer mounted movably with the possibility of angular rotations about its longitudinal axis of symmetry and translational movement relative to the longitudinal axis of the mentioned frame and provided on one side of the two shoulders of the lever carries two spring-loaded by a compression spring thrust, pivotally connected to the finger rigidly mounted on the supporting sheet of the ledge, and on the other gear that interacts with a toothed sleeve rigidly mounted on the saddle anchor hitch of the towing vehicle.

In Fig.1 shows a General view of a trailer equipped with anchor hitch, Fig.2 - his view with a cross section in a longitudinal vertical plane, train, and Fig.3 a top view along arrow A.

Anchor hitch trailer consists of a base plate 1, is rigidly fixed on the frame 2 of the tractor vehicle 3, which by means of the hinge 4 is connected with the seat 5. The saddle 5 conta is Vigna posted by the bolt 10, equipped with the gear 11 connected with a toothed sleeve 12 made in the saddle 5, and two shoulders lever 13. On the lever 13 by means of bearings 14 mounted on the fingers 15, installed thrust 16, provided with a compression spring 17 that is pivotally interconnected with the finger 18 rigidly mounted on the supporting plate 6. The saddle 5 is Rethimno coupling mechanism 19.

Works reference hitch trailer as follows. Straight-line trains, as shown in Fig.1, the traction force from the towing vehicle 3 is transmitted from the seat 5 through the pin 10, which is fixed on the saddle 5 ruthenocene mechanism 19 as is the case in serial constructions of the support-coupling devices, cars, trucks, plate 6 of the ledge 7, and hence the semi-trailer 8. While the gap between the end part of the semi-trailer 8 and the cab of the towing vehicle 3 is minimum (about 200 mm, not more) and remains constant. While maneuvering the towing vehicle 1, i.e., its rotation, for example, the arrow In (Fig.3), the saddle 5 also starts to rotate in the same direction, as well as its toothed sleeve 12 is connected with its teeth with the teeth of the gear 11, and the latter rotates in the same direction, rotating the bolt is rotating in the same direction two shoulders of the lever 13, which carries one of the rods 16 in the direction of arrow C, and the other moves in the direction of arrow D. thus, the first rod 16 acts on the finger 18 and the second contributes to the compression of its spring 17. The movement thrust by the arrow 16 With facilitates the movement of the semi-trailer 8 by the arrow E, which their longitudinal groove 9 slips relative to the bolt 10. Such movement of the semitrailer 8 provides increased clearancebetween the cab of the towing vehicle 3 and the end part of the trailer 8, enabling the latter to perform angle rotation, follow car-truck 3. After the end of the maneuver the vehicle turns in the direction opposite to the arrow B, and rod 16 is moved in the opposite direction to the arrows C and D, providing the movement of the trailer 8 in the direction opposite to the arrow E due to the force generated by a compressed spring 17 of the traction bar 16, which is moved in the direction of arrow D. the Turning of the towing vehicle in the opposite direction of the arrow In the direction of the same algorithm. In order to carry out the dissolution of the combination with Rethimno coupling mechanism 19 is released the bolt 10 and using the supporting device (not shown), commonly known in practice, pripodnimayut-tractor 3, roll out the latest from under the trailer 8.

Feasibility advantage of the proposed technical solutions in comparison with the known obvious, since it allows to significantly increase the capacity of trains due to the automatic regulation of the gap between the cab of the towing vehicle and the trailer when it is maneuvering. This figure could reach as high as 6-8%, which ultimately will reduce the cost of transportation, especially in cases where trains are operated on long-distance transport.

Claims
