Abstract

The disclosure concerns a spring assembly with a leaf spring. The leaf spring extends in a vehicle longitudinal axis, supports a vehicle axle and is connected at least indirectly to a vehicle superstructure at a front end and at a rear end. In order to provide a wheel suspension with advantageous springing and damping behavior that is optimized with regard to weight and complexity, according to the disclosure it is provided that at least one damping region, which is at least partially fluid-filled, is integrated in the leaf spring.
