Abstract

A torsion beam bushing assembly, comprising a cylindrical bushing assembly with mounting lugs and a stop ring at one end of the cylindrical bushing assembly, the cylindrical bushing assembly with mounting lugs It is a one-piece component formed by vulcanizing the bushing outer casing, the integrated shaft-shaped bushing inner sleeve and the rubber material filled in the axial annular space between the bushing outer casing and the integrated shaft-shaped bushing inner sleeve. The one-piece shaft-shaped bush inner sleeve is an integral part including the bush inner sleeve and the lugs at both ends, and the stop ring is a flange with threads in the inner hole. In this state, the cylindrical bushing assembly is press-fitted onto the torsion beam through interference fit, and the limit ring is integrated with the integrated shaft-shaped bushing inner sleeve installed on the torsion beam through threaded connection. The torsion beam suspension using the torsion beam bushing assembly improves the assembly accuracy, the performance and reliability of the whole vehicle, and is convenient in processing, manufacturing and installation, and has low cost.

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 Figure 4 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 5 As shown, the assembly relationship is: part 3a is vulcanized together with part 1a and part 2a to form a small ...
