Embodiment Construction

[0012] figure 1 A cross-sectional view of a device for damping vibrations and limiting torque according to the present invention is shown. The device for damping vibrations and limiting torque is connected to a hydraulic line 1 and on the right side of the device has a receptacle for a connector by means of which the device can be connected to another pressure line. Inside the device for damping vibrations and limiting torque there is an insertion device 2 which is connected to the fluid line 1 . In this case, the connection can be made materially, positively or non-positively, for example by welding, wedging, clamping or the like. Connected to the insertion device 2 is a housing 5 in which a channel is formed for forming a Helmhertz resonator. The sealing between the housing 5 and the insertion device 2 is achieved by a sealing ring 6 , which is arranged between the housing 5 and the insertion device 2 . The channel in the housing 5 is connected to the inner chamber of the...

Abstract

The invention relates to a device for damping pressure vibrations and limiting torque within a hydraulic system for actuating a clutch of a motor vehicle, comprising a pressure line (1) through which a fluid flows. The device comprises a hollow cylindrical double-walled housing (5) which operates on the basis of a Helmholtz resonator, which is designed as a vibration absorber, which forms a channel, and the end face opening of which is closed by a cover. The housing is equipped with an insert (2) that has an inner pressure chamber through which the fluid flows, which comprises a pressure chamber wall, and which has openings in the pressure chamber wall for the inflow or outflow. A movable diaphragm (3) is arranged in the pressure chamber, said diaphragm being designed to be moved from at least one opening to at least one other opening by the fluid flow in the pressure chamber and at the same time to come into contact with the pressure chamber wall in the region of at least one opening. The diaphragm (3) has at least two diaphragm openings, at least one diaphragm opening being closed by the pressure chamber wall when the diaphragm comes into contact with the pressure chamber wall.

Description

technical field [0001] The invention relates to a device for damping pressure vibrations and limiting torque, which device is located within a hydraulic section of a motor vehicle for clutch actuation, which device has the features of the preamble of claim 1 . Background technique [0002] Vibrations are transmitted from the internal combustion engine of the motor vehicle to the clutch. Taking this as a starting point, the vibrations are transmitted further via the disengagement system to the disengagement pedal or clutch pedal and can even be amplified there. In order to reduce the amplitude of the transmitted vibrations, vibration dampers are used, which work according to the principle of Helmhertz resonators and damp vibrations in a defined frequency range around the resonance frequency. [0003] DE 10 2008 003 991 A1 discloses a solution for suppressing inherent resonances in hydraulic lines for clutch actuation of motor vehicles, wherein a specially shaped Helmholtz re...
