Embodiment Construction

[0026] exist figure 1 A schematic sectional view of the manipulating device 1 according to the invention is shown in . The actuating device 1 has a housing 14 in which a central engagement part 4 is arranged on the piston 3 . In the lower left region, the central joint part 4 has a camber 8 which extends approximately over a quarter of the circumference of the central joint part 4 . A magnet 13 is arranged in the camber 8 . The central joint part 4 is covered by a cover 6 . In the illustrated embodiment of the handling device 1 , the cover 6 is partially shown in section, so that the shape and position of the central joint 4 can be seen. The cap 6 has a connection 11 at the lower end. The connection 11 is designed as a cylindrical through connection socket. In the embodiment shown, the connection 11 is closed by a closure.

[0027] The cover 6 is made of plastic, for example. The central joint part 4 is made of aluminum, for example. When the clutch is open or closed, ...

Abstract

The invention relates to an actuating device (1) for a friction clutch, which actuating device (1) has a cylinder (2) which forms a working chamber, in which an axially movable piston (3) is arranged. The friction clutch exerts a twisting moment on the piston. On the side which faces away from the friction clutch, the piston has a central engaging mechanism (4). The central engaging mechanism is prestressed by means of a spring. The central engaging mechanism is covered to the outside by a cap (6), against which the central engaging mechanism rubs.

Description

technical field [0001] The invention relates to an actuating device for a friction clutch. Background technique [0002] Automatic transmissions have been used in different types of vehicles for a long time. These include, for example, stepped automatic transmissions, dual clutch transmissions and continuously variable transmissions. In general, an advantage of an automatic transmission is that the gear ratio between the input speed and the output speed is variable and the different gear ratios can be controlled automatically. A transmission is to be understood here as an element which takes part in changing the transmission ratio and is at least partially engaged in the power flow, regardless of its possible structural division into different structural components. [0003] The switching command for changing the gear ratio is usually switched into a transmission switching position by means of switching elements actuatable via pressure medium, such as clutches and / or brake...
