6.1.1 Overview
Working principle and composition of shock absorber
When the shock absorber moves up and down, the pressure difference P between the cavities forces the shock ab-
sorber oil to pass through the damping hole or valve system, generating damping force. Roles of shock absorber: A.
Support the body. B. Transfer the counterforce of the road surface on the vehicle body. C. Ease the body impact and
weaken the body vibration. D. Restrain the vehicle bounce and improve the grounding of the tire to the ground to en-
sure the vehicle safety.
