All-in-one electric wheels with integrated driving, braking, suspension and steering functions

Abstract

The invention provides an integrated electric wheel integrating the driving function, the braking function, the suspension function and the steering function. The integrated electric wheel comprises a hub motor, a brake, an in-wheel suspension, a steering motor, a motor suspending device, a hub, a rim, a spoke and a tire; the in-wheel suspension comprises a second spiral spring and a second absorber; the motor suspending device comprises a first spiral spring and a first absorber; the steering motor is arranged in the second absorber, the hub motor is arranged on the motor suspending device, an inner housing is connected with an annular base plate, an outer housing is connected with the spoke through a flexible coupling disc, power is transmitted to the hub through the flexible coupling disc, a circular base plate is connected to the upper end of the in-wheel suspension, the lower end of the in-wheel suspension is connected to an electric wheel connecting shaft, and the shaft end is connected to a frame through a flange. According to the integrated electric wheel, the motor suspending device, the suspension and the steering motor are further integrated in the wheel, the integration degree is high, the structure is compact, and the light weight of the integrated electric wheel structure can be effectively achieved.

Description

technical field [0001] The invention belongs to the technical field of electric vehicles, and in particular relates to an integrated electric wheel with integrated driving, braking, suspension and steering functions. Background technique [0002] Increasing environmental pollution and increasing energy shortages have accelerated the development of electric vehicles. Among them, the in-wheel motor-driven electric vehicle has attracted the attention of researchers because of its advantages of simplifying the chassis structure, improving transmission efficiency, increasing the available space of the vehicle, and facilitating the active control of the vehicle. There are two driving modes of in-wheel motor-driven electric vehicles: deceleration drive and direct drive. The former motor generally adopts a high-speed inner rotor motor, and then installs a planetary gear reduction mechanism with a high reduction ratio between the motor and the wheel; the latter mostly uses a low-spe...

Problems solved by technology

The hub motor is integrated in the electric wheel, which increases the unsprung mass of the vehicle. At the same time, the excitation from the road surface will also cause the phenomenon of uneven air gap of the motor, which will further aggravate the vibration caused by the hub motor and affect the ride comfort of the vehicle. and riding comfort, so it is necessary to improve the installation method of the hub motor in the drive wheel
