The invention discloses a vibration reduction assembly, a suspension device and a vehicle. The vibration reduction assembly comprises a vibration reduction part, a fluid pump and a motor, the vibration reduction part comprises a cavity and a piston piece, an inner cavity is formed in the cavity, at least part of the piston piece is movably attached to the inner side wall of the inner cavity and divides the inner cavity into a first cavity and a second cavity, the fluid pump communicates with the first cavity and the second cavity, and the motor is in transmission connection with the fluid pump. The fluid pump can drive the motor through fluid flowing through the fluid pump, and/or the motor can drive the fluid pump to drive the fluid in the fluid pump to flow. According to the vibration reduction assembly, the piston piece can do piston motion in the inner cavity, so that fluid is pressed to react on the piston piece, and damping vibration reduction is achieved. The fluid can drive the motor to rotate when flowing through the fluid pump, the motor can convert kinetic energy of the fluid into electric energy, and energy recovery is achieved. Damping vibration attenuation and energy recovery can be independently controlled and decoupled and can also be mutually coordinated and matched, and the applicability can be improved.

    本发明公开了一种减振组件、悬架装置和车辆。减振组件包括减振部、流体泵和电机,减振部包括腔体和活塞件,腔体形成有内腔,活塞件的至少部分活动地贴合内腔的内侧壁,并将内腔分隔为第一腔和第二腔,流体泵连通第一腔和第二腔,电机传动连接流体泵,减振组件配置为,使流体泵能够通过流过流体泵的流体驱动电机,和/或,使电机能够驱动流体泵以带动流体泵内的流体流动。上述减振组件,活塞件可以在内腔做活塞运动,使得流体受压而能够反作用于活塞件,实现阻尼减振。流体流经流体泵时可带动电机转动,电机则可以将流体的动能转化为电能,实现能量回收。阻尼减振和能量回收能够独立控制和解耦,也可以相互协调配合,有利于提高适用性。
