Embodiment Construction

[0010] Further description will be made below in conjunction with accompanying drawings.

[0011] exist figure 1 The shown wheel side motor of the new energy vehicle is installed in the structural diagram of the rear wheel of an ordinary car. According to the current situation that most of the existing cars use disc brakes, the four front and rear wheels of ordinary cars are equipped with disc brakes. 1. Install new energy vehicle wheel motors in the remaining space of the 4 disc brakes. 2. The models of the disc brakes in the 4 wheels are the same as the models of the wheel motors and their structural features.

[0012] Take the structure of the right rear wheel of an ordinary car as an example below: figure 2 , image 3 , Figure 4 Among them, the right rear wheel is provided with a wheel shaft 3, a left bearing 4 and a right bearing 5 are arranged on the wheel shaft, a wheel hub 6 is installed on the outer circle of the left bearing and the right bearing, a locking oute...

Abstract

The invention provides a new energy vehicle wheel-side motor which is formed by a curved stator and a disc rotor. The motor is a flat-type brushless permanent magnet motor with an axial magnetic circuit, and the disc rotor is fixed on the right side of a hub to follow wheel rotation, and the curved stator is fixed to the right side of a brake disc frame and is still. The wheel-side motor directlydrives a wheel, a ring shape is formed by the curved stator installed on the brake disc frame and a fan-shaped brake, the remaining space of the fan-shaped brake in the wheel is effectively utilized by the curved stator, and the disc rotor is very thin and does not take up too much space. Therefore, according to the wheel motor, the structure of an existing disc brake is not changed, the motor canbe directly installed in the wheel, the work of the disc brake is not affected, and the disassembly of the wheel is not affected. Since 4 wheel-side motors drive 4 wheels separately, the power of each wheel-side motor is equivalent to 1 / 4 of the power of a centrally driven motor. Therefore, the wheel-side motor has a small size and a light weight and is conveniently and effectively applied to anordinary car.

Description

technical field [0001] The invention relates to a motor drive device of a new energy vehicle, specifically a wheel side motor of a new energy vehicle. Background technique [0002] At present, in the field of motor drive technology for new energy vehicles, there is a wheel-side motor integrated in the wheel that directly drives the wheel, which has the advantages of not needing to change the structure of the engine drive system and having no mechanical transmission loss. extensive attention. The invention patent with the application number "2015107137673" and the title "a wheel motor drive device" provides a technical solution in which the wheel motor and the brake are integrated in the wheel. Its shortcoming lies in: the structure of the wheel motor It is more complicated, the cost is high, and it is not compatible with the existing ordinary car brakes, and it cannot be directly upgraded and transformed into a new energy vehicle on the basis of the existing ordinary cars. ...
