The invention discloses a hydraulic bushing assembly, a suspension assembly with the hydraulic bushing assembly and a vehicle, the hydraulic bushing assembly comprises a first hydraulic bushing and a communication assembly, the first hydraulic bushing is provided with a first hydraulic cavity, the communication assembly is communicated with the first hydraulic cavity, so that a liquid medium in the first hydraulic cavity can enter the communication assembly, and the first hydraulic cavity is communicated with the communication assembly; and a liquid medium in the communicating assembly can enter the first hydraulic cavity. According to the hydraulic bushing assembly, the liquid medium in the first hydraulic cavity flows out when bearing the impact load and flows back after the impact load disappears, the impact feeling of passengers can be weakened, under high-frequency external load excitation, the hydraulic bushing assembly can effectively attenuate vibration energy, it is guaranteed that the dynamic stiffness of the first hydraulic bushing is always in a low range, and the service life of the first hydraulic bushing is prolonged. The damping effect is improved, the comfort of a vehicle is improved, liquid media of the first hydraulic bushing can be all forced to flow out, lower dynamic stiffness can be brought, and the performance requirements of extreme working conditions are effectively met.
本发明公开了一种液压衬套组件和具有其的悬架总成、车辆,液压衬套组件包括:第一液压衬套和连通组件,第一液压衬套具有第一液压腔,连通组件与第一液压腔连通,以使第一液压腔内的液体介质能进入到连通组件,以及连通组件内的液体介质能进入到第一液压腔。根据本发明实施例的液压衬套组件,第一液压腔内的液体介质受到冲击载荷时流出,以及在冲击载荷消失后回流,可减弱乘客冲击感,在高频率外部载荷激励下,液压衬套组件能有效衰减振动能量,保证第一液压衬套动刚度始终在较低范围,提高减振效果,提高车辆舒适性,且第一液压衬套的液体介质可全部受迫流出,可带来了更低的动刚度,有效满足极端工况的性能要求。
