Embodiment Construction

[0015] The energy recovery shock absorber and the energy recovery vehicle suspension system provided by the present invention will be further described below in conjunction with the accompanying drawings.

[0016] As shown in Fig. 1 and Fig. 2, the energy recovery energy shock absorber 10 provided by the present invention includes a sleeve 1, a piston 2, wherein, a wire magnet 3 and a coil 4 are also included, and the magnets 3 are a pair, respectively fixed On the inner wall of the sleeve 1 and the N pole of one magnet 3 is opposite to the S pole of the other magnet 3, the piston 2 is located in the magnetic field formed by the magnet 3 in the sleeve 1, and the coil 4 evenly surrounds the piston 2 outside.

[0017] Wherein, the magnet 3 can be any type of magnet, preferably a permanent magnet. The greater the magnetism of the magnet 3, the greater the damping force generated by the shock absorber 10.

[0018] Preferably, the magnetic field formed by the magnet 3 is a unifor...

Abstract

The invention provides a damper with energy recovery, comprising sleeve, piston, magnet and coil. There are two said magnets, which are fixed on the inner wall of sleeve respectively and the N pole of one magnet is opposite to the S pole of the other magnet. Said piston is set in the magnetic field formed by magnet in the sleeve. Said coil is round the outer of piston evenly. The invention also provides a vehicle suspension system with energy recovery, comprising damper unit, control cell and battery. Said damper unit comprises multiple dampers with energy recovery provided in the invention. The damper with energy recovery provided in the invention can realize the generation of energy recovery voltage by the principle of DC line generator so as to transform the mechanical vibration energy into electrical energy. The vehicle suspension system with energy recovery provided in the invention can realize adaptive control to damper and the control is relatively simple. The energy usage is improved.

Description

field of invention [0001] The invention relates to a shock absorber and a vehicle suspension system. Background technique [0002] The suspension system of a vehicle is a general term for all components connected between the body and the wheels, including shock absorbers. When the vehicle is driven on different roads and the wheels are subjected to random vibrations, the suspension system attenuates this part of energy through the shock absorber, and the elastic support between the vehicle body and the wheels is realized, thereby effectively suppressing and reducing the vibration of the vehicle body. The dynamic load and vibration of the wheels ensure the ride comfort and handling stability of the car. [0003] At present, the commonly used shock absorber uses the flow of viscous liquid inside to obtain the required damping force to attenuate the vibration, and at the same time, the vibration energy is converted into heat energy and consumed in the atmosphere. Therefore, i...
