Steering knuckle assembly structure for hub motor driven vehicle

Abstract

The invention provides a steering knuckle assembly structure for a hub motor driven vehicle, and belongs to the field of automobile chassis. The steering knuckle assembly structure comprises a steering knuckle, a shock absorber mounting bracket, a lower swing arm mounting bracket and a brake caliper mounting bracket, the shock absorber mounting bracket and the brake caliper mounting bracket are fixedly arranged on the same side of the steering knuckle, the shock absorber mounting bracket is arranged at the upper end of the steering knuckle, the brake caliper mounting bracket is installed on the right side of the steering knuckle, the lower swing arm mounting bracket is fixedly arranged at the lower end of the steering knuckle, a hub motor shaft installation hole is formed in the middle ofthe steering knuckle, a lower swing arm installation hole is formed in the lower swing arm mounting bracket, and a steering pull rod installation spherical hinge hole is formed in the end, away from the brake caliper mounting bracket, of the upper portion of the steering knuckle. The left steering knuckle and the right steering knuckle of the vehicle are shared, the manufacturing and developing period of a sample piece is shortened, the cost is saved, the chassis is light, and the strength is high.

Description

technical field [0001] The invention belongs to the field of automobile chassis and relates to a steering knuckle assembly structure for a vehicle driven by a hub motor. Background technique [0002] Hub motor, in layman's terms, is a drive motor that directly combines the metal hub and the drive device into a whole, in other words, the drive motor and the transmission and braking device are combined into the hub, commonly known as "electric wheel", also called wheel Wheel motor, which contains bearings, stators and rotors, small inverters, etc. [0003] At present, the widely used steering knuckle assembly for automobile McPherson suspension that everyone is familiar with mainly has the following structural forms: one-piece steering knuckle assembly structure, that is, shock absorber mounting bracket, brake caliper mounting bracket, lower swing arm The mounting bracket is an integral structure, and the commonly used material is ductile iron. The steering knuckle assembly a...

Problems solved by technology

[0003] At present, the widely used steering knuckle assembly for automobile McPherson suspension that everyone is familiar with mainly has the following structural forms: one-piece steering knuckle assembly structure, that is, shock absorber mounting bracket, brake caliper mounting bracket, lower swing arm The mounting bracket is an integral structure, and the commonly used material is ductile iron. The steering knuckle assembly adopts an integral structure. Although the structure is simple, the left and right steering knuckles need to be cast and processed separately. Cost savings and lightweight chassis are also disadvantageous

[0004] The mainstream of traditional vehicles adopts an integrated steering knuckle assembly structure. The left and right steering knuckles cannot be interchanged with one common piece, which increases the development cycle and cost of the steering knuckle. Traditional micro-vehicle steering knuckles generally use ductile iron materials, which is not conducive to lightweight chassis. Traditional vehicles adopt an integrated steering knuckle assembly structure, and the left and right interchangeability is poor. In order to further enable the left and right steering knuckles to share one piece, shorten the processing and production cycle, reduce weight and save costs, it is urgent to design and develop a new structure of the hub motor.
