Heavy type commercial vehicle V-shaped thrust rod assembly and assembly method thereof

Abstract

The invention discloses a heavy type commercial vehicle V-shaped thrust rod assembly and an assembly method thereof. The V-shaped thrust rod assembly comprises a V-shaped end socket assembly, a small end socket assembly and a connecting rod; the V-shaped end socket assembly comprises a V end reinforcing type spherical hinge, a V end spring collar and a V-shaped end socket; and the small end socket assembly comprises a small end spherical hinge, a small end spring collar and a small end socket. The assembly method of the heavy type commercial vehicle V-shaped thrust rod assembly includes the steps that firstly the V-shaped end socket and the small end socket are connected with each other through the connecting rod in a frictional welding mode, then the V-shaped end socket assembly and the small end socket assembly are assembled, and the heavy type commercial vehicle V-shaped thrust rod assembly is formed. In the assembly method of the heavy type commercial vehicle V-shaped thrust rod assembly, both the V end spring collar and the small end spring collar are pressed into a clamping groove of the V-shaped end socket or the small end socket through a specialized pressing device, and the specialized pressing device is composed of a guide mechanism, an upper pressing plate, a pressing head, a transition taper sleeve and a positioning seat. According to the technical scheme of the heavy type commercial vehicle V-shaped thrust rod assembly and the assembly method thereof, the weight of a V-shaped thrust rod can be reduced by 10-15%, the fatigue resistant strength of the heavy type commercial vehicle V-shaped thrust rod assembly and the power of a heavy type commercial vehicle are improved, the service life of the thrust rod assembly is prolonged, the fuel consumption is reduced, and the exhaust pollution is lowered.

Description

technical field [0001] The invention relates to the technical field of commercial vehicle accessories, in particular to a heavy-duty commercial vehicle V-shaped thrust rod assembly and an assembly method for heavy-duty commercial vehicles under severe road conditions. Background technique [0002] The V-shaped thrust rod assembly is a key force-transmitting component of the suspension of a commercial vehicle. It is mainly used to keep the position of the axle relatively fixed and to transmit the longitudinal force or lateral force of the commercial vehicle. At the same time, it can also transmit forces and moments in other directions to ensure a definite motion relationship between the wheels and the body. As one of the key components of the vehicle suspension, the V-shaped thrust rod not only significantly improves the vehicle's carrying capacity, but also The lateral stability of the vehicle has been greatly improved. The V-shaped thrust rods of existing domestic heavy-du...

AI Technical Summary

Problems solved by technology

The V-shaped thrust rods of existing domestic heavy-duty commercial vehicles mainly adopt the joint bearing structure, which has the following defects: First, when the commercial vehicles are running, the V-shaped thrust rod assembly is subjected to continuous and alternating loads, especially for vehicles. The force on the bridge end is the largest, and the end of the joint bearing thrust rod is not well sealed, and sand and sand can easily enter the end, which will accelerate wear and tear, resulting in a decline in the performance of the entire assembly and a greatly reduced service life.

Second, when heavy-duty commercial vehicles are on non-highway road conditions, especially in harsh road conditions such as open-pit mines and large-scale construction sites, the road surface of the vehicle is poor in softness and hardness, the surface road resistance coefficient is large, the operation intensity is high, and the overload is serious, which is easy to cause V-shaped Thrust rod premature failure

Third, the end of the traditional V-shaped thrust rod is 80-90mm inserted into the connected steel pipe and then hot riveted, which increases the weight of the V-shaped thrust rod assembly
