Problems solved by technology

[0004] (1) In the stiffness requirements of the torsion beam bushing assembly, the torsional stiffness and the yaw stiffness are increased synchronously. In order to ensure better vehicle handling performance and comfort performance, a smaller torsional stiffness and a larger yaw stiffness are required. This is often difficult to achieve

Abstract

The invention discloses a torsion beam rear suspension frame lining assembly. The torsion beam rear suspension frame lining assembly comprises an inner sleeve, an outer sleeve, a rubber lining, a lining bracket I, a lining bracket II and inner reinforcing rubber, wherein the inner sleeve and the outer sleeve are arranged between the lining bracket I and the lining bracket II; the rubber lining is vulcanized between the inner sleeve and the outer sleeve; the inner reinforcing rubber is arranged between the lining bracket II and the rubber lining. The inner reinforcing rubber is additionally arranged on a rubber lining assembly of a vehicle torsion beam rear suspension frame, the defect of low deflection stiffness of an ordinary lining under the condition that the torsion stiffness is met can be solved; the best torsion stiffness and the deflection stiffness can be obtained by adjusting the height h of the inner reinforcing rubber and the working height H of the rubber lining.

Description

technical field [0001] The invention relates to a rubber bush assembly for automobiles, in particular to a rear suspension bush assembly. Background technique [0002] The torsion beam semi-independent suspension is a commonly used car rear suspension structure at present. It has the advantages of simple structure, low cost, and small space occupation. The torsion beam suspension is fixed on the main beam through the torsion beam bushing assembly. The force is very complex, mainly including the torsional moment when the parallel wheel jumps, the yaw caused by the angle of the bushing arrangement, the yaw force generated by turning and passing through the pit, etc. [0003] During the design verification process, the following problems exist: [0004] (1) In the stiffness requirements of the torsion beam bushing assembly, the torsional stiffness and the yaw stiffness are increased synchronously. In order to ensure better vehicle handling performance and comfort performance, ...
