Problems solved by technology

[0010] However, active devices with moving seals also have disadvantages, especially with regard to media compatibility over the life of the product
Incompatibilities are also observed with different brake fluids and their components, which after some time lead to leaks in the system
It also has the consequence that this type of master cylinder is prone to high noise emissions due to the brake fluid and especially harsh noises due to the stick-slip effect

Embodiment Construction

[0046] The drawings are partly of a schematic nature and are only used for the understanding of the invention. The figures relate to a longitudinal section, ie a section which extends along a longitudinal axis through the clutch drive, in particular along a rotational axis through the piston. Identical elements are provided with the same reference numerals. The features of the individual exemplary embodiments can also be combined with one another. That is, they can be interchanged with each other.

[0047] exist figure 1 shows an active clutch device 1 according to the invention. The clutch drive 1 is installed in a single clutch or a double clutch. The active clutch device is intended to be installed in a motor vehicle, such as a passenger car, a truck or other commercial vehicles. The clutch drive 1 is mechanically connected to an adjusting element 2 (eg lever 3 ). The rod 3 is surrounded by a bellows 4 . Rod 3 is connected to piston 5 . Piston 5 is mounted axially m...

Abstract

The invention relates to a clutch drive device (1) for a clutch of a motor vehicle, having a piston (5) which can be mounted on a mechanical adjustment element (2) and which is at least axially movable in a housing ( 6) is supported in a form that can move back and forth, wherein the piston (5) abuts on a high-pressure chamber (7) that changes size during movement, wherein the piston (5) and the housing (6) ) between two sealing means (10), of which one, as primary sealing means (11), fluid-tightly seals the high-pressure chamber (7) prepared for receiving hydraulic fluid, wherein in said The piston (5) internally configures ( / arranges / defines) the high pressure chamber (7). The invention also relates to a clutch having such a clutch drive (1).

Description

technical field [0001] The invention relates to a clutch active device for a (double / single) clutch of a motor vehicle, such as a (double / single) clutch for a passenger car, a truck or other commercial vehicles, the clutch active device has a A piston on a type adjusting element, said piston is supported in a housing movable back and forth at least axially movably, wherein the piston adjoins a high-pressure chamber which changes in size during movement, wherein between the piston and the housing There are also two seals, preferably independent of each other, in between, one of which as primary seal fluid-tightly seals the high-pressure chamber prepared to receive hydraulic fluid. Background technique [0002] Various hydraulic clutch master cylinders (CMC; ClutchMaster Cylinder) are known from the prior art for conventional release systems. The present invention is in this field. The invention lies notably in the subfield of sealing arrangements. [0003] According to the...
