Abstract
A hydraulic bearing including a journal bearing (1) and a supporting bearing (2) which are connected to each other by a spring body (3) made of a rubber elastic material and border on at least one working space (4) and at least one compensating space (5), the working space (4) and the compensating space (5) being each filled with a damping fluid and communicating through a damping device (6) so as to conduct fluid. Damping fluid can flow through the damping device (6) when the journal bearing (1) and supporting bearing (2) are radially displaced relative to one another.
Claims20
A hydraulic bearing, comprising:
- a journal bearing and a supporting bearing which are joined by a spring body made of a rubber elastic material and border on at least one working space and at least one compensating space, the working space and the compensating space being each filled with a damping fluid and communicating through a damping device in a fluid-conducting manner, wherein, in response to relative radial displacement of the journal bearing (1) and the supporting bearing (2) with respect to one another, the damping device (6) can have damping fluid flowing through it.
. The hydraulic bearing according to claim 3, wherein the working space (4) has two variable volume fluid pockets (9.1, 9.2) extending axially, communicating through at least one throttle opening (11).
. The hydraulic bearing according to claim 2, wherein the compensating space (5) is bordered on the side facing the surroundings (12) by a membrane (13) which is designed like rolling bellows and accommodates a volume essentially without pressure.
