Embodiment Construction

[0054] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0055] figure 1 It is an embodiment of the present invention, and its cross-linking mode is "left and right cross-linking, front and rear communication", mainly including left front pump type energy feed shock absorber LF, right front pump type energy feed shock absorber RF, left rear pump type energy feed shock absorber The energy-feeding shock absorber LR and the right rear pump-type energy-feeding shock absorber RR; the structure of the four pump-type energy-feeding shock absorbers is the same, and all have hydraulic power generation modules. flow in the opposite direction, and then drive the hydraulic power generation module to generate electricity; among them, the oil outlet LF1 of the left front pump energy-feeding shock absorber, the oil inlet RF2 of the right front pump energy-feeding shock absorber, and the oil outlet of the left rear pump energy-feeding Po...

Abstract

The invention discloses a pump-type feedback energy corsslinking suspension system which comprises four pump-type feedback energy shock absorbers identical in structure. Each pump-type feedback energy shock absorber is provided with a hydraulic power generation module, oil generated from the suspension system under road excitation flows unidirectionally, so that the hydraulic power generation module is driven to generate power. Different oil flowing modes can be realized by changing crosslinking modes, such as 'left and right crosslinking and back and forth crosslinking', 'opposite angle crosslinking' or 'single-wheel self-communicating'; the above crosslinking modes can be switched among one another by adding a control valve block, and different vehicle control performance can be achieved. In addition, semi-active control of a suspension can be realized by allowing a generator to be externally connected with load control, and handling stability and riding comfort of the vehicle can be improved.

Description

technical field [0001] The invention belongs to the technical field of vehicle suspension, and in particular relates to a pump-type energy-feeding cross-linked suspension system capable of effectively recovering the vibration energy of the suspension. Background technique [0002] When the vehicle is running on the road, the excitation from the uneven road surface, as well as the maneuvers such as turning, accelerating, braking, etc. will cause the vehicle to vibrate. The automobile suspension system is used to resist the vertical force acting between the chassis and the body generated by the uneven road surface, vehicle dynamic roll and pitch, and vehicle internal excitation. Limiting fluctuations is an important part of the vehicle system. [0003] In the traditional passive suspension, the hydraulic shock absorber is installed in parallel with the suspension spring to ensure the ride comfort, handling stability and safety of the vehicle. Most traditional shock absorbers...
