Abstract

This utility model relates to an electric vehicle component, specifically a rear trailing arm independent suspension structure for electric vehicles. It includes a wheel, a wheel hub, a brake drum, and a drum brake assembly. The key feature is that it also includes a trailing arm assembly, which is fixed to the wheel hub via an axle. The trailing arm assembly is equipped with a damping spring and a coil spring, which are inclined. Compared with existing technologies, this utility model uses a trailing arm independent suspension, which has advantages such as simple structure, light weight, and low installation height.

Description

A rear trailing arm type independent suspension structure for an electric vehicle

technical field

The utility model relates to an electric vehicle component, in particular to a rear longitudinal arm type independent suspension structure for the electric vehicle.

Background technique

Electric vehicles refer to vehicles powered by vehicle-mounted power supplies, driven by motors to drive wheels, and meeting the requirements of road traffic safety regulations. Electric vehicles can be divided into three types: battery-type pure electric vehicles, fuel cell electric vehicles and hybrid electric vehicles. .

In the prior art, the rear suspension of an electric vehicle generally adopts a non-independent type, and its installation height is large and its structure is complicated when the vehicle structure is arranged.

Contents of the invention

The utility model provides a rear longitudinal arm type independent suspension structure for an electric vehicle, which adopts the longitudinal arm type independent suspension and has the advantages of simple structure, light weight, small installation height and the like.

The technical scheme that the utility model specifically adopts is:

A rear trailing arm type independent suspension structure for an electric vehicle, comprising a wheel, the wheel is provided with a hub, and the wheel hub is provided with a brake drum and a drum brake assembly, and is characterized in that it also includes a trailing arm assembly, a trailing arm The assembly is fixed on the wheel hub through the wheel shaft, and the trailing arm assembly is provided with a damping spring and a coil spring, and the damping spring and the coil spring are arranged obliquely.

Further, one of the damping spring and the coil spring is inclined forward, and the other is inclined backward.

Further, the suspension buffer block is also included, and the suspension buffer block is arranged in the coil spring, so that the volume of the utility model can be reduced.

In addition, an in-wheel motor is installed in the wheel hub.

The advantages of the present invention are:

1) Compared with non-independent suspension, the utility model has simple structure and light weight;

2) The utility model has a small installation height and a high bearing strength;

3) Arranging the suspension buffer block in the middle of the coil spring can make the structure more compact.
