Hydraulically damped engine mounting having decoupling membrane which closes opening in channel disc in fluid-tight fashion with adjustable tension

摘要

A hydraulically damped engine mounting which can be switched has a conical elastomer spring as a support spring, which is connected to a pedestal connecting piece and is supported on a support spring housing that for its part, is supported directly or via intermediate pieces on a support connecting piece and rigidly connected to this. Between the support spring and the support connecting piece is inserted a channel disc in which or with whose help a throttle channel can be available. This connects a hydraulic working chamber formed between the support spring and the throttle channel disc in fluidic fashion to a compensation chamber that is designed between the channel disc and a compensation membrane. There is a decoupling membrane (23) which closes an opening (22) in the channel disc (8) in fluid-tight fashion and whose tension can be adjusted between a decoupled volume flexibility and a tension coupling the throttle channel.
