Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1-5, the traction device for the heavy-duty vehicle comprises a tubular beam 1, wherein a sleeved support 2 is fixedly connected to the middle of the tubular beam 1, and two ends of the tubular beam 1 are fixedly connected with a connecting seat 3. The suit support 2 includes fixed plate 201, the first solid fixed ring 202 of fixed connection and the solid fixed ring 203 of second are distinguished at the both ends of fixed plate 201, the solid fixed ring 204 of the middle part fixed connection of fixed plate 201 and the solid fixed ring 202 of first fixed ring and the solid fixed ring 203 of second with the side position of third, suit support 2 overlaps through the solid fixed ring 202 of first fixed ring, the solid fixed ring 203 of second and the solid fixed ring 204 of third and establishes at the middle part of tubular beams 1 to weld with tubular beams 1. Two sides of the fixing plate 201 are provided with first mounting holes 205 for fixing the towing pintle. The sleeved support 2 is connected with the pipe beam 1 in a sleeved mode in a three-section welding mode, the stress concentration area of the pipe beam 1 is reduced, the maximum stress point of the pipe beam 1 under stress is reduced, the safety factor of the pipe beam 1 is increased to 1.2 times under the same environment, the phenomenon that the stress of the two ends of the traction device is uneven and the threads of the connecting seat are damaged is avoided.
The connecting seat 3 is of an L-shaped structure, the connecting seat is symmetrically and fixedly connected to two sides of the tubular beam 1, a second mounting hole 4 is formed in the outer edge of the connecting seat 3, a square frame is arranged on the upper portion of the connecting seat 3, the top end of the square frame is fixedly connected with a bending plate 5, and a third mounting hole 6 is formed in the bending plate 5. Under the same environment, the safety factor is about 1.3 times of the structure of the special-shaped plane connecting seat, and the strength of the part is improved. The connecting seat 3 is provided with a conical round boss 7, the conical round boss 7 is welded and fixed with the tubular beam 1 in a sleeved mode, the casting process of the connecting seat 3 is simplified, the product consistency is improved, the casting cost is reduced, compared with a bolt connection mode, the assembling process is simplified, and the strength of the connecting seat 3 is not weakened. The connecting support 8 is welded on the connecting seat 3, the connecting support 8 is Z-shaped and is of an integrally formed structure, the connecting support 8 is divided into three parts which are connected smoothly by a middle bending section, the other side of the connecting support 8 faces to the middle of the tubular beam 1 and is provided with a positioning hole 9, and the connecting support 8 is located below the tubular beam 1.
