Problems solved by technology

However, since the motor is directly installed with the wheel, the mass of the motor is increased on the basis of the original wheel, resulting in a significant increase in the mass of the new wheel system, which brings a series of problems:
[0004] 1. Although the quality of the vehicle is greatly reduced, the mass below the shock absorber of the vehicle, referred to as the unsprung mass, that is, the mass of the wheel is greatly increased, which will adversely affect the handling, comfort and suspension reliability of the vehicle
[0005] 2. Fix the precision motor to the wheel hub. The vibration shock of the wheel caused by the uneven road surface is easily transmitted to the motor itself through the wheel hub, so that the motor will be subjected to severe vibration up and down with the wheel for a long time and harsh working environments such as water and dust. Resulting in reduced motor reliability

Embodiment 1

[0045] In the technical solutions disclosed in one or more embodiments, such as Figure 1-19 As shown, an electric wheel system integrating shock absorption and power generation includes a wheel 1, a drive motor 3, a wheel shock absorber 2 and a main shock absorber 6, and the main shock absorber 6 is fixedly connected to the drive motor 3 through an axle 5 The fixed part of the axle 5 realizes the fixation and support of the drive motor 3; the rotating part of the drive motor 3 is connected with the wheel steel ring 1.2 of the wheel through the wheel shock absorber 2, and is used to pass the driving force of the drive motor 3 through The wheel shock absorber 2 is transmitted to the wheel to realize the driving of the wheel.

[0046] In this embodiment, the rotating part of the driving motor 3 is the power output part, which is connected with the rotor of the motor, and the stationary part of the driving motor 3 is the stator part, so as to realize the stable support of the mot...

Embodiment 2

[0080] The present embodiment also provides the working method based on the above-mentioned wheel system, as follows:

[0081] The driving method is as follows: the drive motor 3 is powered on, the shell of the drive motor 3 drives the wheel shock absorber 2 to rotate around the main shaft, the wheel shock absorber 2 drives the outer steel ring 1.2 and the tire 1.1 to produce a rotary motion, and the tire 1.1 is in contact with the ground , to generate forward or backward driving force to complete the driving requirements of the vehicle.

[0082] The axle shaft 5 and the main shaft of the driving motor 3 are fixedly connected, and can not rotate relatively in the course of work, and the shell of the driving motor 3 can rotate around the axle shaft 5 . The casing of the drive motor 3 forms a connection with the steel ring 1.2 through several wheel shock absorbers 2, so that the wheels can be driven to rotate.

[0083] Wheel system braking method:

[0084] The brake disc 1.3 i...

Embodiment 3

[0103] This embodiment provides a vehicle, the wheels of which use the electric wheel system integrated with shock absorption and power generation described in Embodiment 1. Through the electric wheel system, functions such as driving, shock absorption, power generation, braking, and damping adjustment of the vehicle are realized.

Abstract

The invention provides an electric wheel system integrating shock absorption and power generation, a working method thereof, and a vehicle. The electric wheel system comprises a wheel, a driving motor, a wheel shock absorber and a main shock absorber, and the main shock absorber is fixedly connected with a fixed part of the driving motor through an axle and is used for fixing and supporting the driving motor; and the rotating part of the driving motor is connected with wheel steel ring of the wheel through the wheel shock absorber and is used for transmitting driving force of the driving motorto the wheel through the wheel shock absorber. The five functions of driving, shock absorption, power generation, braking and damping adjustment are integrated, rigid connection between the wheel andthe driving motor is changed into flexible connection, secondary shock absorption is increased, the controllability and comfort of the vehicle are further improved, meanwhile, the unsprung mass is reduced, and vibration impact borne by the motor is reduced.

Description

technical field [0001] The present disclosure relates to the technical field related to the electric wheel system, and in particular, relates to an electric wheel system integrating shock absorption and power generation, a working method and a vehicle. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art. [0003] The electric wheel is to directly install the drive motor inside the wheel, and directly drive the wheel through the motor, also known as hub motor technology. Because transmission components such as the engine, gearbox, clutch, and transmission shaft of the original fuel vehicle are omitted, the vehicle structure is simplified. However, since the motor is directly installed with the wheel, the mass of the motor is increased on the basis of the original wheel, resulting in a significant increase in the mass of the new wheel system, which bri...
