Hydraulically damping bearing for construction of cars has working chamber and balancing chamber that are coupled with each other by overflow channel and separate bypass channel that is operated by actuator

摘要

The bearing has a working chamber (13) and a balancing chamber (14) that are filled with a hydraulically damping liquid and are separated by a plate (15). The working chamber and the balancing chamber are coupled with each other by an overflow channel (18) and a separate bypass channel (19). The bypass channel is operated by an actuator (20) and has an actuator element (21) and an actuator drive (22). The actuator is provided in the plate and the actuator element can be moved vertically to the plate. The bypass channel is arranged radially outside the actuator.
