Combined recycling and comprehensive utilizing apparatus and method of inertia energy of car wheels and vibration energy of suspension

Abstract

The invention discloses a combined recycling and comprehensive utilizing apparatus and method of inertia energy of car wheels and vibration energy of a suspension, belonging to the technical field of car energy conservation and emission reduction. The method comprises the following steps: first connecting a plunger pump between a sprung mass and an unsprung mass of a car suspension in a floating manner, and driving a hydraulic pump to work by using vibration displacement generated when a car drives on a fluctuated pavement; additionally fixing an inner gear ring on a car wheel hub, when the car wheel rotates, enabling power to be sped up by virtue of an inner gear transmission machine, and directly driving the hydraulic pump / hydraulic motor to work; when a car brakes and decelerates, rapidly converting a great amount of inertia energy of the wheel to hydraulic energy to be stored; and when the car is started and sped up, directly providing two portions of hydraulic energy converted from the vibration energy of the car suspension and the inertia energy of the car to the wheel by virtue of a hydraulic motor mode. The recycled hydraulic energy can select a corresponding mode according to a road condition and can be applied to hydraulic assistance of a car steering device and a disc-type brake hydraulic system.

Description

technical field [0001] The invention relates to a combined recovery and comprehensive utilization system of the inertial energy of automobile wheels and the vibration energy of the suspension, belonging to the field of automobile energy saving and emission reduction. Background technique [0002] When the car is driving on the road, the unevenness of the road surface and the driving behavior such as acceleration and deceleration of the car will cause the relative displacement of the sprung mass and the unsprung mass of the car, thereby generating a certain amount of vibration energy. Due to the existence of passive shock absorbers in traditional suspensions, This part of the vibration energy will be dissipated into the atmosphere in the form of heat and lost. In addition, more than one-third of the energy of the car engine is used to overcome the rolling resistance of the running car wheels, and when the car brakes, decelerates, and slides downhill, it will generate huge ine...

AI Technical Summary

Problems solved by technology

[0004] At present, the vibration energy of the automobile suspension and the inertial energy recovery device of the wheel are relatively complex in structure, the transmission chain is long, and most of them are for the recovery of a single energy, which is not conducive to the effective centralized recovery of the discrete energy of the vehicle.
