Leaf spring double-wishbone type independent rear suspension of coach

Abstract

The invention relates to a leaf spring double-wishbone type independent rear suspension of a coach.The leaf spring double-wishbone type independent rear suspension comprises two leaf spring lower wishbones, two half axles, two layer plates, two leaf spring upper wishbones, two bolt brackets, two U-shaped bolts, two wheel-side supports, two support plates, six connecting transverse beams, a main speed reducer, two speed reducer upper supports, two height adjusting valves, two dampers, four leaf spring connecting devices, eight support blocks, eight spherical hinges, two brake systems and four elastic elements.The leaf spring double-wishbone type independent rear suspension has the advantages that the brake performance of the coach can be improved, the elastic elements are mounted on the bent leaf spring layer plates, accordingly, the leaf spring double-wishbone type independent rear suspension has a low mounting height and can be mounted on a coach body with longitudinal beams, and required mounting spaces can be diminished.

Description

technical field [0001] The automobile suspension system structure of the present invention is particularly a leaf spring double wishbone independent rear suspension of a bus. Background technique [0002] At present, passenger cars rarely use double wishbone independent suspension schemes on the rear suspension. The rear suspension of passenger cars generally adopts the more economical non-independent suspension, and the double-wishbone independent suspension is relatively expensive; the double-wishbone independent suspension is composed of four cross arms, and the upper and lower cross arms are generally composed of castings. , so the total mass is generally very large, making it impossible for the braking system to provide sufficient braking force. Double wishbone independent suspension has a complex structure, and the airbag is generally installed on the upper wishbone, which requires a lot of space for installation. Contents of the invention [0003] The purpose of t...
