Embodiment Construction

[0025] figure 1 A hydraulic shock mount 10 for use as an engine mount in a motor vehicle is shown. The carrier 10 has a suspension spring 11 made of elastomer material, which supports a core 12 on the engine side. The suspension spring 11 is supported on the edge of the housing 17 which delimits the support 10 on the outer circumference. The suspension spring 11 delimits a working chamber 13 which is separated from the compensation chamber 14 by a partition 15 . The compensation chamber 14 is delimited by an elastically resilient compensation cap 16 made of elastomer material.

[0026] Hydraulic fluid is filled in the working chamber 13 and the compensation chamber 14 . A flow passage 18 communicating with the working chamber 13 and the compensation chamber 14 is provided in the partition 15 , and the flow passage has a helical path. Furthermore, the working chamber 13 and the compensating chamber 14 communicate with each other via a vertically extending bypass channel 19 ...

Abstract

A hydraulic damping mount has a working chamber and a compensating chamber, which are filled with a hydraulic liquid and separated from each other by an intermediate plate. The working chamber and the compensating chamber are connected to each other via a transfer passage and a bypass channel. The bypass channel can be opened or closed by an actuator. The actuator is configured as a one-piece elastomer part, which has a fastening portion on the edge and an actuating element, which is connected to the fastening portion via a flexible connecting portion.

Description

technical field [0001] The invention relates to a hydraulic shock absorber with a working chamber and a compensating chamber, which are filled with hydraulic fluid and are separated from each other by a partition, wherein the working chamber and the compensating chamber are connected by a flow passage and a bypass The bypass channel communicates with each other, and the bypass channel can be opened or closed by the actuator. Background technique [0002] Such a mount is known from German Patent Application Publication No. DE 10332081 A1. The actuator arranged in the center of the partition has a sliding sleeve in the shape of a hollow cylinder which is pressed against the partition by a return spring when no vacuum is applied so that the opening in the partition is closed. When vacuum is applied, openings in the partition are opened. The actuators used have multiple parts and are therefore complex in structure. Contents of the invention [0003] It is therefore an objec...
