Definitions
- the invention relates to the technical field of automobile parts manufacturing, in particular to a sliding column assembly and a vehicle using the same.
- the sliding column assembly is the general term for all the force transmission connecting devices between the car frame (or body) and the axle (or wheels). Its function is to transmit the force and torque between the wheel and the frame, and buffer The impact force transmitted from the uneven road to the frame (or body) reduces the vibration caused thereby to ensure the smoothness of the car.
