Embodiment Construction

[0025] exist figure 1 A clutch system for a vehicle drive train with a vibration decoupling system 1 according to the invention is schematically shown in .

[0026] The clutch system has a clutch 1 for disconnecting and connecting the power flow in the drive train. Furthermore, a disengaging mechanism for the clutch 2 is provided as adjusting element 3 in the clutch system, which is used for engaging and disengaging said clutch 2 . Furthermore, the clutch system has a clutch actuator as actuator 4 .

[0027] The actuating device 4 is provided with an active element 5 . The active element 5 is, for example, a ball screw of an electrical linear unit or a piston rod of a hydraulic or pneumatic cylinder and carries out a first active movement for manipulating the adjusting element 3 in a predetermined active direction W and in the opposite direction. A second acting movement in direction W' of said acting direction W.

[0028] Furthermore, the vibration decoupling system 1 is ...

Abstract

In order not to transmit vibrations, for example from a drive train of a vehicle, to an actuating device (4) for a clutch (2), a vibration decoupling system (1) is provided. The vibration decoupling system (1) has: an adjusting element (3); an actuating device (4) with an active element (5) which is designed to act in a predetermined direction of action (W, W' ) to implement an active movement; and a vibration decoupling mechanism (6), which connects the active element (5) of the actuating device (4) to the adjustment element (3). The vibration decoupling mechanism (6) has a predetermined clearance range in a predetermined action direction (W, W'), and the action element (5) or the adjustment element (3) is within the clearance range movement without the corresponding other of the active element or the adjustment element moving together.

Description

technical field [0001] The present invention generally relates to a vibration decoupling system, in particular a vibration decoupling system for use in a vehicle drive train. Background technique [0002] Vehicles are usually equipped with an internal combustion engine, which is connected to the drive wheels via a drive train. In order to be able to disconnect the internal combustion engine from the drive wheels, for example when the vehicle is stationary, it is known to provide a clutch in the drive train of the vehicle. In passenger cars in particular, the clutch is frequently actuated via a Bowden cable which is connected to a clutch pedal for the driver. Instead, an alternatively installed automatic shift clutch is provided with a dedicated actuation device. [0003] During driving, however, vibrations, so-called judder, occur in the drive train, which vibrations are also transmitted to the clutch. However, in clutches that are shifted by means of a special actuating ...
