Description

Technical Field

[0001] The utility model mainly relates to the field of a V-shaped thrust rod, in particular to a hollow shell of a V-shaped thrust rod. Background Art

[0002] The main function of the V-type thrust rod is to stabilize the axle and prevent it from shifting forward, backward or left and right when the car turns or is overloaded. One end of the V-type thrust rod is hinged to the frame through a spherical pin, and the other end is installed on the axle and hinged to the axle through a spherical bearing. In this way, the V-type thrust rod can help overcome the disadvantage that the spring steel plate can only transmit longitudinal force and lateral force, but cannot transmit traction, braking force and its corresponding reaction torque. When the truck is overloaded, the V-type thrust rod can effectively and evenly distribute the impact load to the longitudinal beams on both sides of the car body, thereby reducing the impact on the axle housing and chassis.

[0003] At present, the large end of the V-type thrust rod connected to the frame is formed by forging. However, due to the limitations of the forging process, when a larger shell is forged, the mounting hole for the spherical pin is a solid structure during forging, and subsequent drilling is required to obtain the mounting hole. This processing method makes the processing technology more complicated, the processing time is longer, and the processing cost is high. In addition, this method requires more materials, and the material cost is also high, resulting in material waste. Utility Model Content

[0004] In order to solve the deficiencies of the prior art, the utility model provides a V-shaped thrust rod hollow shell, which can improve production efficiency, save materials and reduce production costs.

[0005] In order to achieve the above purpose, the utility model is implemented through the following technical solutions:

[0006] A V-shaped thrust rod hollow shell comprises a mounting head and a connecting part. The mounting head is provided with a circular mounting cavity, the top of the mounting head is provided with a first groove, and the connecting head is arranged at the end of the connecting part.

[0007] The connecting portion is bent toward the outside of the mounting head at a certain angle, and the connecting portion is an arc transition.

[0008] A connecting rib is arranged on the side of the connecting portion facing the first groove, a second groove is arranged on the top of the connecting rib, and the second groove is adapted to the first groove.

[0009] The installation cavity is an annular cavity, and the installation cavity and the installation head are forged integrally.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] The utility model divides the large end of the V-shaped thrust rod into two parts for forging, thereby reducing the thickness of the forging, so that the installation cavity of the large end shell can be directly forged, and the installation cavity can be formed by simple subsequent lathe processing or boring processing. After the forging is completed, the two halves of the workpiece are butt-jointed and welded to obtain a complete installation head. The device makes the overall processing efficiency higher and the material cost and processing cost lower. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Attached Figure 2 It is a schematic diagram of the main viewing angle structure of the utility model.

[0014] The numbers shown in the accompanying drawings are: 1, mounting head; 2, connecting part; 3, connecting head; 4, connecting rib; 11, mounting cavity; 12, first groove; 41, second groove. DETAILED DESCRIPTION

[0015] The utility model is further described in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are only used to illustrate the utility model and are not used to limit the scope of the utility model. In addition, it should be understood that after reading the content taught by the utility model, those skilled in the art can make various changes or modifications to the utility model, and these equivalent forms also fall within the scope defined by this application.

[0016] like Figure 1-2 As shown, a V-shaped thrust rod hollow shell described in the utility model includes a mounting head 1 and a connecting portion 2. The mounting head 1 has a circular mounting cavity 11 therein, and the mounting cavity 11 is an annular cavity, and the mounting cavity 11 is forged during forging. The top of the mounting head 1 has a first groove 12, and the first groove 12 is used as the weld during welding. A connecting head 3 is provided at the end of the connecting portion 2, and the connecting head 3 is used to connect the V-shaped connecting rod at the rear end. The connecting portion 2 is bent toward the outside of the mounting head 1 at a certain angle, and the connecting portion 2 is a circular arc transition. During forging, the connecting portion 2, the mounting head 1 and the connecting head 3 are all forged as one piece.

[0017] The connecting portion 2 has a connecting rib 4 on the side facing the first groove 12, and a second groove 41 is arranged on the top of the connecting rib 4. The second groove 41 corresponds to the first groove 12, and the heights of the second groove 41 are consistent, so that welding can be completed after the two shells are butt-jointed.

[0018] The V-shaped thrust rod hollow shell in the utility model is divided into two halves, which can be welded into one body through tooling positioning after forging, thereby solving the problem that the shell is forged as a solid body as a whole, which has a large weight, high price and low material utilization rate.

[0019] The material utilization rate of the V-type thrust rod shell in the prior art is only 60%. The present device adopts left and right split forging, and the blank is a hollow structure, so the material utilization rate is increased to 90%. It is welded together through tooling positioning, which reduces the weight of the blank, improves the material utilization rate, reduces the material cost and processing cost, and has obvious price advantages.
