Abstract

In the embodiment described in the specification, a cushion bearing for motor vehicles has two rigid bearing seats with a resilient rubber bearing block and an air spring acting between the seats. The air spring has a bellows forming a chamber divided into two compartments by a throttling plate which is connected to one of the bearing seats by way of a central rod and a rigid housing connected to the other bearing seat encloses the bellows. The bellows has at least one intake valve so that the air spring is automatically pumped up during relative motion between the bearing seats.
