Embodiment Construction

[0065] exist Figure 1-Figure 3 shows a hydraulic damping bearing 10 according to the present embodiment, which is put into use as a running gear bearing or a powertrain bearing.

[0066] The support 10 has a hollow cylindrical core 12 , an outer sleeve 14 surrounding the core and an elastic mount 16 connecting the core 12 to the outer sleeve 14 .

[0067] especially if figure 2 As shown, the support 16 has two support pads 18a, 18b protruding from the core 12 opposite to each other in the radial direction R, which divide the inner cavity formed between the core 12 and the outer sleeve 14 into a first working cavity 20 And the second working chamber 22. The working chambers 20 , 22 are filled with fluid and connected by a damping channel 23 .

[0068] Such as figure 1 As shown, the support 16 has two cavity walls 24a, 24b, which are preferably designed as expandable flexible elastic membranes. The chamber walls 24 a , 24 b delimit the two working chambers 20 , 22 at the ...

Abstract

The invention relates to a hydraulically damping bearing (10) with a core (12), an outer sleeve (14) surrounding the core (12), and an elastomeric carrier body (16) which connects the core (12) and the outer sleeve (14) to each other, wherein the carrier body (16) separates a first working chamber (20) and a second working camber (22) from each other, which chambers are filled with fluid and are connected to each other via a damping channel and at least one overpressure channel (30a, 30b), wherein a pivotable valve element (32a, 32b) is provided which is attached at three sides to the carrierbody (16), wherein the valve element (32a, 32b), in a closure position, closes the overpressure channel (30a, 30b) and, when a predetermined difference limit pressure is exceeded in the working chambers (20, 22), pivots to an open position in order to connect the two working chambers (20, 22) to each other in a fluid-conducting manner, and wherein a separate supporting device (40a, 40b) is provided which bears on one side of the valve element (32a, 32b) and supports the valve element (32a, 32b) in the closure position.

Description

technical field [0001] The invention relates to a hydraulically damped bearing, especially a running gear bearing or a powertrain bearing, having an outer sleeve surrounding a core and an elastic bearing connecting the core to the outer sleeve, wherein the bearing connects the first working chamber and the second working chamber. The cavity is separated, and the first working cavity and the second working cavity are filled with fluid and communicate with each other through a damping channel and at least one overpressure channel. Background technique [0002] Hydraulic damping bearings of the type mentioned in the introduction are used in motor vehicles as chassis or drivetrain bearings to damp and / or dampen occurring vibrations. During the relative movement of the core relative to the outer sleeve or vice versa, one of the two working chambers is compressed. As a result, the fluid currently located there flows into the other working chamber via the damping channel. This re...
