Vehicle
By introducing a cooling circulation system and a pumpless design into the hydraulic suspension system, the circulation of the liquid medium is achieved, solving the problem of the inability of the liquid medium to circulate within the damping device. This improves the vehicle's damping performance and temperature management, while reducing energy consumption and maintenance costs.

AI Technical Summary
Technical Problem
In existing hydraulic suspension systems, the liquid medium within the damping device cannot circulate, which limits temperature management and damping performance improvement, affecting vehicle comfort and safety.
Method used
By incorporating a cooling circulation system within the damping device, the liquid medium circulates within the lower storage chamber and the cooling circulation system. The vibration of the powertrain drives the piston to move, achieving pump-free circulation of the liquid medium and enhancing damping performance and temperature management.
Benefits of technology
It improves the damping performance of the suspension system, reduces low-frequency vibration, lowers energy consumption and maintenance costs, and enhances vehicle safety and stability.

Abstract
The utility model discloses a vehicle, the utility model relates to vehicle technical field, and the vehicle includes: the liquid medium flows in cooling circulation system to carry out heat exchange with the component of vehicle, and the suspension system is connected between power assembly and the vehicle body, and the power assembly is located the upper portion of suspension system, the damping housing forms to have the liquid storage chamber, and the piston is movably arranged in the liquid storage chamber along the height direction of vehicle, to divide the liquid storage chamber into upper liquid storage chamber and lower liquid storage chamber, and the damping housing is fixed to the vehicle body, and the piston is fixed to the power assembly, and the liquid medium import and liquid medium export of damping housing all are linked with lower liquid storage chamber, and cooling circulation system links liquid medium import and liquid medium export, to make the circulating flow of liquid medium in lower liquid storage chamber and cooling circulation system. Therefore, without setting up the pump body, can realize the circulating flow of liquid medium in damping device, and then realized the damping performance promotion and temperature management of suspension system, reduced the energy consumption and maintenance cost of vehicle.
