Hanger bracket assembly, hanger bracket with the hanger bracket assembly and vehicle with the hanger bracket

Abstract

The invention discloses a hanger bracket assembly, a hanger bracket with the hanger bracket assembly and a vehicle with the hanger bracket. The hanger bracket assembly comprises a balance beam, a supporting beam and a bag type air bag. The supporting beam is arranged on the balance beam and can rotate in a pivoted mode relative to the balance beam. The bag type air bag is arranged on the supporting beam. The hanger bracket assembly can greatly reduce impact force received by a vehicle frame, so that the comfort of the vehicle can be greatly improved, and the service life of the vehicle can be prolonged.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a suspension assembly, a suspension with the suspension assembly and a vehicle with the suspension. Background technique [0002] Traditionally, in vehicles with double rear axles, such as heavy trucks, cement mixers, pump trucks, cranes and other heavy vehicles (including road vehicles and off-road vehicles), there are generally two types of suspension: leaf spring suspension frame and air suspension. [0003] For the leaf spring suspension, there is a balance support in the middle of the two drive axles. The upper end of the balance support connects the middle of the leaf spring (leaf spring) through the balance shaft. The leaf spring and the balance seat can be rotated through the balance shaft. The two ends of the leaf spring are installed on the upper end of the axle, so that the rear axle load of the vehicle is transmitted to the axle through the balance support, balance ...

AI Technical Summary

Problems solved by technology

[0004] The rigidity of the leaf spring suspension is relatively large, and the impact on the road surface is large during driving, and the vehicle itself also bears a large impact, thus reducing the service life of the vehicle and poor comfort, and the weight of the leaf spring suspension is relatively heavy, increasing the Reduced fuel consumption, increased costs

[0005] Each bridge of the traditional air suspension uses a single-bridge double-membrane airbag structure or a single-bridge four-membrane airbag structure. The suspension of the two bridges is connected in series. The traditional air suspension is heavy in weight, high in cost, and too low in stiffness. The roll angle is large and the roll stiffness is low. Therefore, it is necessary to add a stabilizer bar to increase the roll stiffness, resulting in a further increase in the weight of the air suspension, inconvenient layout, affecting passability, poor overall performance, and limited applications.
