Embodiment Construction

[0049] Hydraulic damping support 10 such as figure 1 - The embodiment shown in FIG. 4 is designed as a cylindrical bearing sleeve, which is used as chassis support or unit suspension.

[0050] The bearing 10 has a hollow-cylindrical bearing core 12 which is supported on an outer tube 34 via a support spring 14 . Two chambers 20 , 22 filled with a fluid 24 are formed by the two radially extending support flanges 18 a , 18 b of the retainer spring 14 . The chambers 20 , 22 delimited on the end sides by a not-shown inflatable flexible elastomer membrane communicate with one another via a damping channel 26 and a decoupling channel 30 .

[0051] Furthermore, a window tube 25 is inserted in the support flange 14 . The window tube 25 has two rings 33, 35 interconnected by two opposed webs 37, 39, as figure 2 shown. The connecting strip 37 forms the decoupling channel 30 together with the outer tube 34 .

[0052] A decoupling cage 32 is installed in the decoupling channel 30 . ...

Abstract

A hydraulically damping mount includes amount core and an outer tube. In an embodiment, the mount core is supported on the outer tube via a mount spring of an elastomeric material, and the mount spring divides the space formed between the mount core and the outer tube into at least two fluid-filled chambers that are in fluid communication with each other via at least one damping channel and at least one decoupling channel. In an embodiment, at least one torsion-resistant decoupling device is movable back and forth by fluid flows and is arranged in the at least one decoupling channel. In an embodiment, the decoupling device is formed so that during a fluid induced movement of the decoupling device its inflow sides always face the fluid flows.

Description

technical field [0001] The present invention relates to a hydraulically damped support having a support core and an outer tube, wherein the support core is supported on the outer tube by means of a spring made of elastomeric material, wherein the support spring will be positioned between the support core and the outer tube The space formed between them is divided into at least two chambers filled with fluid, which are in flow-conducting communication through at least one damping channel and at least one decoupling channel, wherein at least one torsion-resistant plate-shaped solution is arranged in the decoupling channel. The uncoupling device is movable to and fro by the fluid flow and is designed such that its upstream side always faces the fluid flow during a fluid-induced movement of the uncoupling device. Background technique [0002] Hydraulic damping mounts are used in motor vehicles to damp and damp occurring vibrations. Hydraulic functions could also be implemented ...
