Damping-adjustable vibration energy recovery device based on spiral planetary gear transmission

Abstract

The invention discloses a damping-adjustable vibration energy recovery device based on spiral planetary gear transmission, and the device comprises a shock absorber which comprises a shock absorber cylinder, a piston and a piston rod; the piston is arranged in the shock absorber cylinder and can move in the axial direction of the shock absorber cylinder. The piston rod is fixedly connected to the piston; the motor cover is fixedly arranged on the shock absorber cylinder in a sleeving manner; the output shaft is rotatably arranged in the motor cover and is connected with the piston rod; the piston rod can drive the output shaft to rotate when moving in the axial direction of the shock absorber cylinder; the planetary gear mechanism comprises a sun gear, a plurality of planetary gears, a planet carrier and a gear ring; the sun gear is fixedly connected to the output shaft; the first motor is fixedly arranged in the motor cover, and a motor shaft of the first motor is fixedly connected with the planet carrier; the plurality of motor shaft gears are respectively meshed with the gear ring; the plurality of second motors are fixedly arranged in the motor cover and are arranged in one-to-one correspondence with the motor shaft gears; a motor shaft of the second motor is fixedly connected with the motor shaft gear.

Description

technical field [0001] The invention belongs to the technical field of energy recovery of shock absorbers, in particular to a damping adjustable vibration energy recovery device based on helical planetary gear transmission. Background technique [0002] The shock absorber is used to suppress the vibration and the impact from the road surface when the spring rebounds after absorbing vibration. Widely used in automobiles, in order to accelerate the attenuation of the vibration of the frame and the body to improve the ride comfort of the car. The compression stroke and extension stroke of the shock absorber will be accompanied by the up and down movement of the piston rod, which will generate energy, while the traditional shock absorber generally does not have an energy recovery device, and only a small part is equipped with a shock absorber energy recovery device. The shock absorber energy recovery devices are all mechanical structures that need to be arranged outside the sho...

AI Technical Summary

Problems solved by technology

Both the compression stroke and the extension stroke of the shock absorber will be accompanied by the up and down movement of the piston rod, which will generate energy, while the traditional shock absorber generally does not have an energy recovery device, and only a small part of the shock absorber is equipped with an energy recovery device for the shock absorber, but the existing The shock absorber energy recovery device needs to arrange more mechanical structures outside the shock absorber, which takes up a lot of space and is not easy to install
