Abstract

A hydraulically damping rubber is provided with an uncoupling element. The bearing has an elastomer arranged between an essentially cylindrical inner part and a cylindrical outer sleeve and connected to the inner part by vulcanization. The hydraulically damping rubber bearing has chambers for receiving a damping agent. The chambers are connected by at least one channel arranged in a channel carrier. The uncoupling element is provided for uncoupling the damping action caused by the circulation of the damping agent in the channel or channels against forces of low exciting amplitude introduced into the bearing. The uncoupling element is a separate component from the hydraulically damping rubber bearing, arranged in a recess in a channel carrier space of the bearing. The uncoupling element includes a frame with a membrane fixed in a freely vibrating manner in or on the frame and a radial distance is assigned to the membrane between the channel carrier and the outer sleeve of the bearing, so that a radially directed movement of the membrane is possible.
