Abstract

The invention discloses a torsion beam lining component, which comprises a barrel-shaped body lining assembly with mounting supporting lugs and an upper limiting frame and a lower limiting frame which are positioned at one end of the barrel-shaped body lining assembly with the mounting supporting lugs, wherein the barrel-shaped body lining assembly with the mounting supporting lugs is an integrated part formed by integrally vulcanizing a lining outer sleeve, an integrated shaft-type lining inner sleeve and a rubber material filled in an axial annular space between the lining outer sleeve and the integrated shaft-type lining inner sleeve; the integrated shaft-type lining inner sleeve is an integrated part comprising a lining inner sleeve and the supporting lugs at two ends; and the upper limiting frame and the lower limiting frame are an upper half flange and a lower half flange which are provided with mounting lug plates and have the same shape. In a used state, the barrel-shaped body lining assembly is pressed on a torsion beam in an interference fit manner; and the upper limiting frame and the lower limiting frame are connected with the integrated shaft-type lining inner sleeve arranged on the torsion beam through mounting bolts to form a whole. By using a torsion beam suspension of the torsion beam lining component, the mounting precision is improved, and the performance and the reliability of the whole vehicle are improved; the torsion beam lining component is convenient to manufacture and mount; and the cost is low.

Description

technical field

[0001] The invention belongs to auto parts and a manufacturing and installing method thereof, in particular to a torsion beam bushing assembly and a manufacturing and installing method thereof. Background technique

[0002] The bushing of the torsion beam is a very important part of the torsion beam suspension. The torsion beam bushing plays the role of alleviating the vibration and impact from the road surface and ensuring the handling and stability; the guiding and buffering of the torsion beam suspension, etc. , is mainly transmitted through this bushing, therefore, the torsion beam bushing is a very complex component under stress.

[0003] The existing torsion beam bushing structure such as image 3 Shown: It consists of outer cylinder 1a, inner sleeve 2a, rubber parts 3a, mounting lug I (4a) and mounting lug II (5a) with flange; as Figure 4 As shown, the assembly relationship is: part 3a is vulcanized together with part 1a and part 2a to form a small a...
