Split type light bearing seat independent suspension system

Abstract

The invention relates to a split type light bearing seat independent suspension system. The split type light bearing seat independent suspension system is composed of two independent suspension devices, wherein the two independent suspension devices are independent with each other and are symmetrically arranged from left to right, and the independent suspension devices comprise bearing seat assemblies, main pin assemblies, knuckle assemblies, knuckle arms, hub brake disc assemblies, brake assemblies, air spring assemblies, damper assemblies and upper and lower A-shaped arm assemblies. The bearing seat assemblies are split, the upper ends of the bearing seat assemblies are connected with the air spring assemblies and the A-shaped arm assemblies, and the middle of the bearing seat assembliesis connected with the knuckle assemblies by virtue of the main pin assemblies; the design of a split type light bearing seat is adopted, so that the requirements of low floor and wide channel can bemet, the weight can be greatly reduced, compared with the same level of the independent suspension system, the total weight of the split type light bearing seat assemblies and the main pin assembliescan be reduced by 40% to 50%, and the split type light bearing seat independent suspension system is especially suitable for new energy electric buses. Additionally, the unsprung mass is reduced, andthe stability and smoothness in control over the whole vehicle are facilitated.

Description

technical field [0001] The invention relates to an independent suspension system for automobiles, in particular to a split-type lightweight bearing seat independent suspension system suitable for low floors and wide passages. Background technique [0002] At present, in the existing commercial vehicle independent suspension system, the axle load is above 3.5 tons, and the independent suspension system adopts the double-wishbone independent suspension structure with a solid kingpin with bearing seat. For example, the Chinese patent application number is 201020550680.1. The large-drop independent suspension front axle assembly, although the layout of the independent suspension system meets the requirements of the low-floor passage width, the structure of the bearing seat is relatively heavy, which increases the unsprung mass and affects the handling stability and ride comfort of the vehicle; For example, the Chinese Patent Application No. 201320726197.8 discloses a support arm...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a split-type lightweight bearing seat independent suspension system to solve the problem that the existing independent system structure cannot meet the lightweight requirements of today's new energy commercial vehicles, and to provide an independent suspension system that is more suitable for new energy buses system
