Electric wheel with energy recovery and multi-direction vibration reduction functions

Abstract

The invention discloses an electric wheel with energy recovery and multi-directional vibration reduction functions. The electric wheel comprises a vertical vibration transfer module, a shimmy transmission assembly, a vibration and shimmy synchronous suppression module, a hub motor module and a wheel module. The vertical vibration transfer module is installed on a vehicle body and comprises an axle and a first connecting block. The first connecting block is fixed on the axle. The axle is rotationally connected with a rotating disc. The wheel module is installed on the rotating disc. The hub motor module comprises a stator, a rotor and a middle transfer disc. The rotor is connected with the rotating disc through the middle transfer disc. The middle transfer disc can transfer a torque of the rotor to the rotating disc and allows the rotor to jump in the radial direction of the rotating disc. The stator is installed on the inner side of the rotor. For the electric wheel disclosed by the invention, through mechanical design in the wheel directly, vibration reduction (vertical vibration and shimmy vibration of the wheel) of the wheel in multiple directions can be realized only by using one vibration reducer.

Description

technical field [0001] The invention belongs to the technical field of automobile wheel vibration reduction, and in particular relates to an electric wheel with energy recovery and multi-directional vibration reduction functions. Background technique [0002] With the popularization of new energy vehicles, the way of motor drive has also changed. Today, some electric vehicles choose to use hub motors to drive. Simply put, a hub motor is a motor that directly integrates the hub and the driving device, that is, the motor, transmission and braking devices are all integrated into the hub. The in-wheel motor makes the structure of the car simpler, resulting in better space utilization, and also facilitates the regular maintenance and repair of the vehicle. It makes the vehicle layout more flexible, eliminates the need for complex mechanical transmission systems, and improves transmission efficiency. The in-wheel motor achieves direct drive in the true sense. For the vehicle, i...

Problems solved by technology

However, the hydraulic shock absorber is a passive shock absorber, its versatility is poor, the damping working range is small, and the damping force cannot be adjusted during work. When the shimmy amplitude or frequency is large, the hydraulic shock absorber cannot effectively reduce the vibration.

Moreover, hydraulic shock absorbers have high requirements on sealing, otherwise oil leakage may occur, which will also reduce the shimmy effect
