Problems solved by technology

However, the stiffness and damping coefficient of the passive suspension are not adjustable, and cannot be changed with the external road conditions. The design can only guarantee the ideal effect under certain working conditions, and the vibration damping performance is limited.
[0003] Chinese patent 201210107000.2 discloses and proposes a shock absorber integrated with inerter and damping. The integrated shock absorber with inerter and damping can better take into account the requirements of driving comfort and safety, and overcomes the traditional passive suspension performance. The shortcomings of fixed parameters solve the technical and cost problems in the practical application of active suspension

Embodiment Construction

[0013] figure 1 is a schematic diagram of a car suspension. Shock absorber 19 , spring 20 and energy storage device 21 are installed in parallel between vehicle axle 18 and vehicle frame 22 , and wheels 17 are installed at both ends of vehicle axle 18 .

[0014] figure 2 It is a structural schematic diagram of the vibration energy recovery device involved in the present invention. Hydraulic cylinder 2 passes through the oil inlet of check valve 4, check valve 6, check valve 11, check valve 12 and high-pressure oil pipe 5, high-pressure oil pipe 10, high-pressure oil pipe 13, high-pressure oil pipe 14 and cycloid hydraulic motor 7 and The oil outlets are connected, and the cycloidal hydraulic motor 7 is connected with the motor 9 through the gear set 8 .

[0015] The relative motion between the sprung mass (body) and the unsprung mass (wheel) is caused by the excitation of uneven road surface and complex road conditions, which causes the suspension system to vibrate, so tha...

Abstract

The invention discloses an energy storage suspension device having a vibration energy recovery function, relates to a vibration energy recovery device for an energy storage suspension, and belongs to the technical field of vehicle energy saving and emission reduction. On the basis of a hydraulic energy storage suspension, an output shaft of a hydraulic motor is connected with a generator through a gear set, so that the vibration energy of the energy storage suspension is converted into electricity to be stored. While the function of the hydraulic energy storage suspension is implemented, the mechanical energy generated from vibration of a vehicle suspension is converted by a motor into electricity to be stored, a novel vibration energy recovery layout scheme is provided, so that the performance of a passive suspension system and the handling stability and the driving smoothness of the vehicle are promoted to be improved, and the effect of energy saving is also exerted.

Description

technical field [0001] The invention relates to an energy storage suspension device with vibration energy recovery, which belongs to the technical field of automobile energy saving and emission reduction. Background technique [0002] Suspension is the general term for all force transmission connection devices between the frame and the axle. According to whether the stiffness and damping of the suspension system are variable, it can be divided into active suspension and passive suspension. Due to the cost and energy consumption of active suspensions, passive suspensions are commonly used on vehicles now. However, the stiffness and damping coefficient of the passive suspension are not adjustable and cannot be changed with the external road conditions. The design can only guarantee the ideal effect under certain working conditions, and the damping performance is limited. [0003] Chinese patent 201210107000.2 discloses and proposes a shock absorber integrated with inerter an...
