Air suspension main beam with rear shock absorber and its assembly

Abstract

The invention discloses a damper rear air suspension girder which comprises a girder body. The girder body comprises a front supporting plate and a rear supporting plate; the front supporting plate is used for fixing a brake chamber; the rear supporting plate is used for fixing an airbag; a damper fixing part is also arranged on the girder body; the damper fixing part is positioned at one side of the rear supporting plate; the damper fixing part is used for fixing a damper. The invention further discloses a damper rear air suspension girder assembly which comprises the damper rear air suspension girder disclosed by the invention. According to the damper rear air suspension girder disclosed by the invention, the damper fixing part is arranged on the girder body, the damper fixing part is positioned at one side of the rear supporting plate, and in the mounting process, the brake chamber is fixed on the front supporting plate and the damper is fixed on the damper fixing part, so that interference caused by the case that the brake chamber and the damper are positioned at the same side is avoided; in addition, the damper is fixed at the rear part of the girder body, so that a damping effect is also reinforced.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a shock absorber rear-mounted air suspension main beam and an assembly thereof which can avoid "interference" between a brake air chamber and a shock absorber. Background technique [0002] The main beam of the air suspension is an important part of the trailer, and the effect of shock absorption for the vehicle body is achieved by installing a shock absorber on the main beam of the air suspension. [0003] The traditional air suspension main beam usually includes a front support plate and a rear support plate. The front support plate is used to fix the brake chamber and the shock absorber, and the rear support plate is used to fix the air bag. The brake air chamber and the shock absorber are fixed on the support plate, and the volume of the brake air chamber is large, and the two ends of the brake air chamber protrude from both sides of the front support plate, resulting in a narrow s...

AI Technical Summary

Problems solved by technology

[0003] The traditional air suspension main beam usually includes a front support plate and a rear support plate. The front support plate is used to fix the brake chamber and the shock absorber, and the rear support plate is used to fix the air bag. The brake air chamber and the shock absorber are fixed on the support plate, and the volume of the brake air chamber is large, and the two ends of the brake air chamber protrude from both sides of the front support plate, resulting in a narrow space for installing the shock absorber Mutual "interference" between the brake chamber and the shock absorber

[0004] In addition, because the existing shock absorber is installed on the front support plate of the main beam of the air suspension, and the upper end of the shock absorber is connected with the vehicle frame, the damping effect of the existing shock absorber is relatively poor.
