Electric driving wheel assembly integrated with driving system, braking system and steering system

Abstract

The invention discloses an electric driving wheel assembly integrated with a driving system, a braking system and a steering system. The electric driving wheel assembly comprises a hub assembly, a driving assembly, a braking assembly and a steering assembly. The hub assembly comprises a hub bearing, a hub bearing outer ring and a hub bearing inner ring, and the hub bearing inner ring is rotationally connected to the inner side of the hub bearing outer ring through the hub bearing; the driving assembly comprises a stator and a rotor, the rotor rotates relative to the stator, the stator is fixedly connected to the outer ring of the hub bearing, and the rotor is fixedly connected to the hub bearing inner ring; the braking assembly comprises a brake disc and a brake hub, the brake hub is fixedly connected with the hub bearing inner ring, the brake disc is fixed to the hub bearing outer ring, a brake shoe is arranged on the brake disc, and a brake electromagnet used for controlling the brake shoe to act relative to the brake hub is fixedly connected to the brake disc. According to the invention, the functions of driving, braking and steering are integrated.

Description

technical field [0001] The invention relates to the technical field of an electric driving wheel assembly, in particular to an electric driving wheel assembly integrating a driving system, a braking system and a steering system. Background technique [0002] The electric drive wheel assembly system integrates the motor into the wheel hub to drive the wheeled chassis or wheeled vehicle. It is a distributed drive chassis or the main driving component of the vehicle form, which greatly simplifies the structure of the wheeled chassis . Most of the existing electric drive wheel assemblies only integrate the drive motor in the wheel hub, and the drive motor control unit is still placed outside the wheel hub. At the same time, additional brake systems and steering systems need to be installed. There are many mechanical transmission connectors, and the installation , Debugging and maintenance are still complex. [0003] At present, the demand for chassis of intelligent driving and...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide an electric drive wheel assembly integrating drive system, braking system and steering system, so as to solve the problem that most of the existing electric drive wheel assemblies proposed in the above background technology only integrate the drive motor on the hub In the interior, the drive motor control unit is still placed outside the wheel hub, and the braking system and steering system need to be installed separately. There are many mechanical transmission connections, and the installation, commissioning and maintenance are still complicated.
