Hydraulic Rebound Stopper affect for passsenger cars on shock absorber

Abstract

The vehicles driving on the road, road-related impacts affect the chassis. These impacts should not be transmitted to the cabin. The That absorbs these impacts between the chassis and cabin is the shock absorber. The shock absorber does this damping by converting motion energy into heat energy. During this energy conversion, the hydraulic flow inside the shock absorber is limited by piston valve. The valve damping force is adjustable according to vehicle type for the passive Shock Absorbers and occurs reaction forces during driving. However, the damping force must be variable in order to meet driving dynamics and driver expectations that change over time. Active shock absorbers are used to provide this variability. However, active shock absorbers are more costly and more difficult to implement. For this reason, different technologies such as hydraulic rebound stopper and hydraulic compression stopper are used in passive shock absorbers to ensure the variability of force. In this study, comparative numerical data were obtained by applying the hydraulic rebound stopper system to the shock absorbers used in small family cars and lower middle-class cars. In road conditions where the reaction force of the valve against the hydraulic fluid is not sufficient, the hydraulic rebound stopper is activated by creating extra force. With this extra force, disturbing vibrations to the vehicle and the driver are dampened, increasing driving safety and comfort.
