Description

The present invention relates to a connection arrangement for connecting a first hydraulic component with a second hydraulic component. The present invention also relates to an actuating system for a clutch of a motor vehicle.

Clutches, in particular friction clutches, for example, also double clutches, serve to interrupt a torque closure of a drive motor to a drive train of a motor vehicle. To actuate such couplings actuating systems or engagement systems are known which comprise at least one master cylinder, a slave cylinder and a hydraulic line connecting them. To connect the hydraulic line with the master cylinder and / or slave cylinder connecting arrangements are used. After maintenance or repair of the actuation system, it may be necessary to vent the actuation system to remove air bubbles in the actuation system.

For this purpose, so-called T-breather are used, which are installed in the hydraulic line. However, such T-breathers require a larger space around the hydraulic line around, so that in the typical application for a clutch only a subsequent assembly of the T-breather in the hydraulic line can be done (first, so a hydraulic line is screwed to a clutch bell of a clutch and subsequently the T-breather is plugged into an adapter on the hydraulic line).

As an alternative to T-venting are for the purpose of venting a hydraulic line from the DE 10 2014 212 441 A1 and DE 10 2015 211 424 A1 so-called sliding ventilator known, wherein one of the connecting elements of the connection arrangement has a vent connection, which is closed in an operating position. To vent the actuating system, the connecting elements are displaced from the operating position to a venting position against each other and along an axial direction, whereby the venting port is opened. For fixing the connecting elements in the operating position and the venting position are in the DE 10 2014 212 441 A1 z. B. form wire springs used as locking elements for which recesses must be formed on the connecting elements for inserting the wire form springs. In the DE 10 2014 211 424 A1 bayonet closures are proposed as locking elements.
