Description

Adjustable damping tandem shock suspension

Technical Field

The utility model relates to the technical field of shock-absorbing suspensions, and more specifically to a damping-adjustable series shock-absorbing suspension.

Background technique

Shock-absorbing suspension is the general term for all force-transmitting connection devices between the frame (or load-bearing body) and the axle (or wheel) of a car. Its function is to transmit the force and torque acting between the wheel and the frame, and to cushion the impact force transmitted to the frame or body by the uneven road surface, and reduce the vibration caused by it, so as to ensure that the car can run smoothly.

Most of today's shock-absorbing suspensions have a single shock-absorbing structure. When vehicles need to transport the wounded on rough roads, muddy roads, and beach roads, since the wounded have already suffered a certain degree of injury, it is unavoidable that secondary injuries will be caused to the wounded during transportation, which results in certain limitations in the use of existing shock-absorbing suspensions.
