Abstract

The invention discloses a hub motor for an unmanned vehicle, which includes a motor body, the motor body includes a central shaft, a stator, a rotor and a resolver, hub fixed end covers and disc brake fixed end covers are installed on both sides of the rotor, and the rotor is arranged on the stator An air gap is formed between the rotor and the stator, the resolver includes a resolver stator and a resolver rotor, an air gap is formed between the resolver stator and the resolver rotor, the resolver stator is fixedly connected to the stator, and the resolver rotor is fixed to the hub The end cover is fixedly connected, and the resolver rotor is fixedly connected with the fixed end cover of the hub through the fixed base of the resolver rotor and the fixed aluminum block of the resolver rotor. The outer edge of the rotor fixing base extends axially to form a fifth protruding ring, and the inner surface of the fifth protruding ring is attached to the outer surface of the fourth protruding ring. The invention adopts double bearing support by increasing the wheel hub support plate, which is firm in installation, high in reliability, and can bear relatively large bearing torsion force.

Description

technical field

[0001] The invention relates to the technical field of motors, in particular to hub motors for unmanned vehicles. Background technique

[0002] The hub motor is a motor designed to integrate the "power system, transmission system, and brake system" of the car. Due to the omission of a large number of transmission bodies, the structure of the vehicle becomes simple, and a variety of complex driving methods can be realized. The in-wheel motor has the characteristics of independent driving of a single wheel, so it can be used in any form of front-wheel drive, rear-wheel drive or four-wheel drive. It is relatively easy to implement, and full-time four-wheel drive is very easy to implement on a vehicle driven by an in-wheel motor.

[0003] The existing in-wheel motors connect the hub with the rotor of the motor, and the rotor rotates to drive the hub to rotate, but the hub is only supported on one side, that is, the hub and the rotor are fixed on one side, and th...
