CN201245052Y - Mounting structure of automobile thrust rod pin subassembly - Google Patents

Abstract

The utility model discloses an installation structure of an automobile thrusting rod pin subassembly, which comprises an end head of a thrusting rod, a pin subassembly mounted in the end head and a clamp spring. The utility model is characterized in that a wire ring attached with the clamp ring is arranged in the end head through screw threads. The utility model has the advantages of difficult deformation of the clamp spring, uniform stress and high withdrawal load, so the service life of the thrusting rod is prolonged.

Description

The mounting structure of automotive track bar pin branch unit

Technical field

The utility model relates to a kind of mounting structure of automotive track bar pin branch unit.

Background technology

In distance rod assembly of automobile, as shown in Figure 1, in termination 6, scurry out in stressed and moment process in order to prevent pin branch unit 5, thereby lose its function, in termination 5, be provided with annular groove, be equipped with in the annular groove with pin branch unit 5 in the end cap jump ring 7 of fitting, there are many following weak points in existing structure:

1, in the press-fiting in the process of jump ring 7, jump ring 7 easily deforms, and the phenomenon that is distorted makes its unbalance stress in use, and it is lower that it withdraws from load, even jump ring 7 and pin branch unit 5 are scrapped;

2, in the loaded vehicle use, there is serious overload problems, therefore require the also corresponding increase of power of transmission with moment, the deflection of pin branch unit 5 its rubber parts also strengthens, jump ring 7 suffered power and moments are increased, owing to unbalance stress, shortened the service life of jump ring 7 and distance rod assembly.

The utility model content

The purpose of this utility model is the above-mentioned deficiency at prior art, and a kind of mounting structure of automotive track bar pin branch unit is provided, it have jump ring be difficult for deforming, stressed evenly, withdraw from the high advantage of load, thereby prolong the service life of propelling rod.

For achieving the above object, the mounting structure of automotive track bar pin branch unit of the present utility model, comprise propelling rod the termination, be installed on pin branch unit, jump ring in the termination, it is characterized in that in the termination, the wire ring of fitting with jump ring being installed by screw thread;

Because jump ring is not yielding when wire ring and jump ring assembling, and is stressed even; And the two is the end face contact, and area of contact is big, and it is high to withdraw from load, has prolonged the service life of propelling rod; And the gap in the pin branch unit outside has been dwindled in the setting of wire ring, makes oarse-grained foreign material be difficult for entering, and has reduced the wearing and tearing to rubber in the pin branch unit, has further prolonged the service life of propelling rod;

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further described.

By Fig. 2 and shown in Figure 3, the mounting structure of this automotive track bar pin branch unit, comprise propelling rod termination 1, be installed on pin branch unit 2 in the termination 1, jump ring 3, be installed in the wire ring 4 of fitting with jump ring 2 in the termination 1 by screw thread.

Claims (1)

1. the mounting structure of an automotive track bar pin branch unit, comprise propelling rod the termination, be installed on pin branch unit, jump ring in the termination, it is characterized in that in the termination, the wire ring of fitting with jump ring being installed by screw thread.
