Abstract
A hydraulic bearing has a cylindrical main housing, a load-bearing spring enclosed by the main housing, a work chamber, which is at least partially enclosed by the load-bearing spring, with a work chamber volume filled with hydraulic fluid. The hydraulic bearing further includes a control diaphragm, which is configured to change the work chamber volume, and an actuator. The actuator is coupled to the control diaphragm for deflecting the same. The hydraulic bearing also includes an equalization chamber and a throttle duct hydraulically interconnecting the work chamber and the equalization chamber, and a cylindrical chamber housing is arranged with a first end face on an outer casing side section of the main housing, wherein the equalization chamber is formed by at least a part of an interior of the chamber housing.
