3) Rebound Spring
In the front shock absorber with a built in rebound spring, the function of the rebound spring that is
provided in the shock absorber case combines with the function of the coil spring in order to restrain
the elongation of the entire suspension during rebounds. Consequently, only the function of the coil
spring is applied when the suspension stroke is small during normal driving, in order to realize a soft
and comfortable ride. However, when the inner wheel makes large rebounds, such as when the vehicle
is cornering, the functions of both the rebound spring and the coil spring are combined in order to reduce
the elongation of the entire suspension. As a result, the vehicle’s excellent maneuverability and stability
have been realized.
