Abstract

The invention discloses an electric vehicle wheel assembly capable of recycling road surface excitation energy. The electric vehicle wheel assembly comprises a wheel, a transmission part, a front damping part and a rear damping part. The transmission part is connected with the front damping part and the rear damping part, and the front damping part and the rear damping part are located at the front end and the rear end of the wheel. The damping part is provided with a lubricating oil way I, the transmission part is provided with a lubricating oil way II, and the two parts are communicated. Wherein each damping part comprises a spring, a hydraulic cylinder, a piston, a piston rod, a one-way valve and a shaft sleeve; an oil inlet of the one-way valve communicates with an oil outlet in the bottom of the hydraulic cylinder, and an oil outlet of the one-way valve communicates with a radial oil hole of the shaft sleeve. The hydraulic cylinder, the one-way valve and the radial oil hole of the shaft sleeve form a lubricating oil way I of the damping part. The electric vehicle wheel assembly has the functions of shock absorption, noise reduction and bearing self-lubricating, impact abrasion of wheel axle vibration to the bearing can be improved, the service life of the bearing and the wheel assembly is prolonged, and the operation and maintenance cost is reduced.

Description

technical field [0001] The invention relates to the technical fields of shock absorbers for electric vehicles and the technical fields of tribology, in particular to an electric vehicle wheel assembly capable of recovering road excitation energy. [0002] technical background [0003] The use of electric vehicles is large and popular, and it plays an important role in getting through the "last mile" of people's travel and urban traffic. With the development of electric vehicle technology, high-speed or medium-high-speed driving on bumpy roads has become a common working condition. The complex road surface excitation causes the wheel shaft to vibrate greatly, and continuously impacts the friction surface of the bearing. Therefore, the wear failure of the wheel bearing has become a common fault in the electric vehicle transmission system, which shortens the service life of the electric vehicle. [0004] The current electric vehicles use hydraulic shock absorbers to improve the...
