V-shaped thrusting rod assembly for rear suspension of heavy truck

Abstract

The invention belongs to the technical field of automobile assembly machinery, and particularly relates to a V-shaped thrusting rod assembly for a rear suspension of a heavy truck. The V-shaped thrusting rod assembly comprises a straight ball seat, a ball pin assembly, a connecting pipe, a middle ball seat, a joint bearing outer ring, an installing seat, an elastic retainer ring and a sealing protecting sleeve, wherein the middle ball seat comprises an upper cover and a casing, the upper cover and the casing are integrally formed, a cavity used for assembling a metal bearing outer ring is formed inside the casing, one end, far away from the upper cover, of the cavity is provided with a retainer ring groove, the installing seat comprises a flat head ball body, a rotating body and a flange plate, the rotating body is positioned between the flat head ball body and the flange plate, the rotating body is respectively in smooth connection with the flat head ball head and the flange plate, the flat head ball body and the joint bearing outer ring are assembled into a pair of friction pairs, and an oil accommodating groove device is arranged in the flat head ball body, is communicated with the outer surface of the flat head ball body through a passage and is communicated with the upper surface of the flat head ball body. The V-shaped thrusting rod assembly has the advantages that the failure can be avoided, the cost is low, and in addition, the service life is long.

Description

technical field [0001] The invention belongs to the technical field of automobile components, in particular to a V-shaped thrust rod assembly for the rear suspension of heavy-duty automobiles. Background technique [0002] Now the more advanced balanced rear suspension of heavy-duty vehicles is generally assembled with left and right independent balance shaft assemblies. The V-shaped thrust rod is used to realize the longitudinal and lateral positioning of the drive axle and transmit various forces and moments. Therefore, the V-shaped thrust rod is a balanced suspension system. It is a very important force-bearing and positioning component. [0003] According to the structure, the V-shaped thrust rod is roughly divided into a mounting seat form and a three-ball form. The common point of the two is that the structure of the two small ball heads at the frame end is basically the same, and the difference is that the connection form of the bridge end is different: the middle ...

Problems solved by technology

[0007] Because the original structure of the joint bearing inner ring has a tapered hole, the overall rigidity of the inner ring is reduced, or because the taper of the inner and outer tapered holes is not well matched, the mounting seat suddenly comes out of the tapered hole of the bearing inner ring after the vehicle has been running for a period of time. Causing the vehicle to stop, or even causing a major accident involving the overturning of the vehicle
