Self-damping electric energy recovery hub

Abstract

A self-damping electric energy recovery hub comprises a rim and a center hub. Airbag damping devices are arranged between the center hub and the rim along the circumference and fixed to the outer surface of the center hub; and the center hub is internally provided with a driving mechanism and an electric energy recovery device, the driving mechanism is connected with the center hub, the center hubis connected with the electric energy recovery device, and the electric energy recovery device is connected with an electric power storage system. When wheels are vibrated, the rims can utilize the buffering function of the airbag damping devices to realize self damping and reduce the amplitude of floating of an outer frame; under the circumstance of no emergency deceleration, a brake pad does not work, the driving mechanism is decelerated, and the electric energy recovery device is switched on, so that kinetic energy of the hub is converted into electric energy, the purpose of deceleration is achieved, meanwhile, the electric energy can be stored to the electric power storage system, and recovery and utilization of energy are realized; and during normal running, the electric energy recovery device is in an open circuit state and in a non-working state.

Description

technical field [0001] The invention belongs to the field of automobile wheel hubs, in particular to a self-damping electric energy recovery wheel hub. Background technique [0002] The hub is the cylindrical, center-mounted metal part that supports the tire on the inside of the tire. Also known as rim, steel ring, wheel, tire bell. There are many types of wheel hubs according to diameter, width, forming method and material. The general wheel hub does not have the function of shock absorption. The wheel hub is installed on the front and rear axles of the car, and the shock absorber is set on the front and rear axles to achieve the purpose of shock absorption. In order to improve the performance of the wheel hub, designers are making continuous efforts in the design and production of the wheel hub. [0003] For example, Chinese Patent Publication No. CN205553765 discloses a new type of shock-absorbing wheel hub, comprising an outer wheel hub and a center wheel hub, the out...

Problems solved by technology

[0006] The purpose of the present invention is to solve the problem that the ordinary wheel hub does not have shock absorption, the outer frame is floating, and the kinetic energy loss of braking cannot be utilized, and realizes a wheel hub that can not only self-shock, but also convert kinetic energy into electric energy and recycle it when braking.
