A thrust rod and bush installation structure

Abstract

The invention belongs to the technical field of automobile parts, and provides a thrusting rod and lining mounting structure. The thrusting rod and lining mounting structure comprises a thrusting rod and a lining body. The lining body is provided with a center hole matched with the thrusting rod. The thrusting rod penetrates through the center hole and is inserted into the lining body in a sliding mode. The thrusting rod and the lining body are locked through a first nut and a second nut arranged at the two ends of the lining body respectively. According to the thrusting rod and lining mounting structure, the thrusting rod is inserted into the lining body in a sliding mode, the two ends of the lining body and the thrusting rod are locked through the first nut and the second nut, the thrusting rod can be made to slide along the lining body axially by unscrewing the first nut and the second nut so as to adjust the position, relative to a vehicle frame, of a ball pin and adjust the kingpin caster angle and the kingpin inclination angle in the four-wheel positioning process, the mounting accuracy of an overall suspension system is improved, and product yield of the overall suspension system is increased.

Description

technical field [0001] The invention belongs to the technical field of automobile parts, and in particular relates to a thrust rod and bush installation structure. Background technique [0002] As the guide and force transmission element of the automobile suspension system, the thrust rod transmits various forces on the wheel to the body, and at the same time ensures that the wheel moves according to a certain trajectory. It elastically connects the wheel and the body through ball pins or bushings. The bushing is installed on the thrust rod, which greatly improves the vibration isolation effect of the suspension system, reduces the noise inside the car caused by the unevenness of the road surface, and also has the function of a spring. [0003] Bushings of the prior art are usually as figure 1 As shown, it includes a metal outer tube 101, a coaxial metal inner tube 103, and a rubber 102 between the two, and the three are usually vulcanized. When assembling, one end of the ...

Problems solved by technology

[0004] The connection between the bush and the thrust rod in the prior art is an interference fit. After the two are connected, the thrust rod and the bush cannot slide relative to each other, but the bush is fixed on the frame, and the ball pin is fixed to the tire through the steering knuckle, and its The position relative to the thrust rod is fixed. Due to manufacturing and assembly errors, the position of the ball pin relative to the frame cannot be adjusted. The caster angle and inclination angle of the kingpin in the four-wheel alignment cannot be adjusted. The assembly accuracy of the entire suspension system cannot be adjusted. It is difficult to guarantee and reduce the yield of production; at the same time, the thrust rod and the bushing have an interference fit. When the bushing fails due to aging and other reasons, it cannot be replaced separately. It needs to be replaced together with the thrust rod, which increases maintenance costs.
