  • Publication number: 20220288988
    Abstract: A suspension for a vehicle is configured such that, even in a situation of departing from a range (spring freedom height) in which a coil spring may be tensioned as a rebound state is added in a full rebound state, a lower end of the coil spring is coupled to a spring pad coupled to a leaf spring and continuously supported, so that the separation of the coil spring connecting a suspension arm to a body member may be prevented. The suspension includes the leaf spring provided at the suspension arm connecting a body frame to a knuckle; a spring pad coupled to the leaf spring; and the coil spring supported, at opposite ends of the coil spring, by the body member and the spring pad, the body member being located above the suspension ann.

  • Publication number: 20220288989
    Abstract: A suspension system for a vehicle includes a spring pad coupled to a spring and configured to support the spring connecting a suspension arm and a vehicle body member of the vehicle, where the spring pad includes: a seat part coupled to an end of the spring; a guide part configured to guide upward and downward movements of the seat part; and an elastic part configured to connect the seat part and the guide part and having a length that varies when the seat part moves. In particular, the spring is consistently supported by being coupled to the seat part of the spring pad even in a situation in which an additional rebound further occurs in a full-rebound situation and the spring deviates from a range in which the spring can be extended, thus preventing withdrawal of the spring connecting the suspension arm and the vehicle body member.
