Heavy-duty combination

 

The invention relates to the field of trackless vehicles. Heavy-duty rig consists of a truck tractor and semitrailer, interconnected anchor hitch. The frame of the trailer has two ledge, interacting with the fifth wheel device of the towing vehicle and the fifth wheel device, placed on the cart trailer driven gear shaft attached to the trailer. The technical result - performance-train for improved maneuverability, versatility and cost reduction in the conditions in the manufacture of trucks in production and operation. 4 Il.

The present invention relates to the field of trackless vehicles and can be used in the design of the trains increased payload.

Known combination (see Shchukin, M. M. Hitch cars and trucks. - M.-L.: the motor cycle", 1961, page 50, Fig.42), which consists of the towing vehicle, equipped with anchor hitch (truck unit) and a semi-trailer, in the middle part of the frame which is made from the ledge with a support sheet and a bolt, Comte is mi, and in the area of transition ledge in her spar geared bearing device for installation of the trailer in a position where the vehicle when separated from the latter. The disadvantage of this combination is, first, its low maneuverability due to the fact that the wheels of the trailer are made unmanaged, secondly, the inability to carry out the coupling of the towing vehicle with the trailer from the side opposite to the ledge of the frame of the trailer, and, thirdly, during unloading of the trailer, and this process in practice, it may take a long time, when, for example, the dimensions of the trailer are made of indoor and semi-trailer used as a storage room, its components and parts are irrational and cannot be applied on other trains, as disassembly and Assembly of the spring complexes and generally rear suspension semi-trailer rather time-consuming and ethnologica in operating conditions.

Known also articulated truck Volvo-A-32(64) (see Quick car guide NIIAT, 10th ed. supplementary and processed - M.: Transport, 1983, page 140), consisting of a truck tractor and semitrailer. The design of such trains are generally similar to those described above and therefore, the shortcomings of their item by improving maneuverability the versatility and cost reduction in production in the manufacture of trucks and their operation.

This objective is achieved in that the rear part of the frame of the semitrailer is equipped with a second ledge with a support sheet and a pin identical to the ledge in front of and similarly interacting with the same saddle device installed on the frame of the moving cart, equipped with springs and wheels, and has a second support device installed along the length of the frame of the semitrailer symmetrically to the first and fifth devices of the tractor and the moving cart hinged bevel gear sectors, spring-loaded by a compression spring relative to the frame of the tractor and the moving cart, interacting with bevel gears fixed on the transmission shaft, laid in bearings of the frame of the trailer in its longitudinal plane of symmetry, and the side and front parts of a body provided with an opening door.

In Fig.1 shows a General view of lorry convoys from the side; Fig.2 is a front ledge of the frame semi-trailer fifth wheel coupling with the device of the towing vehicle; Fig.3 is a kinematic diagram of the connection of the transmission shaft truck is for.

Heavy-duty combination consists of the towing vehicle 1, on the frame 2 which has the saddle device 3 in contact with the supporting sheet 4 of the ledge 5 of the frame 6 of the semi-trailer 7. The rear part of the frame 6 is also connected with such saddle device 3 saddle device 8 mounted on the frame of the moving cart 9. On the fifth devices 3 and 8 by means of hinges 10, with the possibility of angular rotation of the fixed bevel gear sectors 11, which is spring-loaded by a compression spring 12 relative to the frame 2 and frame of the moving cart 9. Bevel gear sectors 11 are interconnected with bevel gears 13, placed in the slots 14 of the support sheet 4 and the gear 13 is fixed on the transmission shaft 15, arranged in bearings 16, which are rigidly fixed on the frame 6 of the semi-trailer 7. On the frame 6 is also mounted support device 17 and the fixed pins 18. The trailer 7 is provided with side 19 and end doors 20.

Works heavy-duty articulated in the following way. While maneuvering the towing vehicle 1 and turn it, for example, to the left along arrow a (see Fig.3) gear sector 11 mounted on the saddle device 3 also rotates in the same direction of the arrow, which contributes to the rotation of the conical systemtrace In the bearings 16 of the frame 6 of the semi-trailer 7. This angular rotation of the transmission shaft 15 provides and turn the other bevel gear 13 also on the arrow In, and since it is interrelated with the bevel gear sector 11, mounted on the fifth wheel device 8, it is rotated along arrow C, causing angular rotation of a frame of the moving cart 9 in the same direction. This position of the wheels of the towing vehicle 1 and the trailer 7 provides movement of trains along the curve of constant radius (Fig.4), and this in turn improves the manageability of such a vehicle. After the end of the maneuver the transition of the towing vehicle 1 is in motion in a straight line is accompanied by its rotation in the direction opposite arrow a, which contributes to the rotation of the transmission shaft in a direction opposite to the arrows In, and turn the frame moving cart 9 opposite to the arrow C, i.e., the combination occupies the position shown in Fig.1. The rotation of the towing vehicle 1 in the opposite direction (Fig.3) in direction of arrow D is similar to the above. At long sludge trailer 7 or unloading his support device 17 is moved by the arrows E. the way into the ground, lifting the trailer 7 by the arrow G, which leads to disengagement of the conical estereoscypica 7 by the arrow N. Then manually or otherwise roll rolling cart by the arrow M, which allows these machines to be used in coupling with another trailer released from the cargo or in the sludge. In the transport position, the bevel gear sectors 11 due to the presence of the compression spring 12 constantly pressed against the conical gear 13 of the gear shaft 15 that, first, creates a reliable engagement of the teeth of the gear and, secondly, provides the necessary torque T that occur on said shaft, and hence reliable angular rotation of a frame of the moving cart 9. At the same time, when the trailer 7 is when separated from the towing vehicle 1 position, unloading his body can be carried out with all 4 sides on the perimeter due to the presence of the doors 19 and 20.

Feasibility advantage of the proposed technical products in contrast to the known constructions obvious, since it can significantly reduce fleet of cars, trucks and moving trucks semi-trailers through the use of their transportation when transporting the body when it is delivered to the place of loading or unloading trailers do not require the presence of such aggregates. At the same time it o trucks and universality of the coupling of the trailer with any two of their end sides will reduce the cost of production of trains and to improve the performance of the trucks, especially used for long-distance long-distance transport.
