Embodiment Construction

[0029] figure 1 A cross-sectional view of a clutch slave cylinder 1 according to the prior art is shown. The clutch slave cylinder 1 comprises at least one first annular piston 2 which is linearly displaceable in the direction of the axis A in a first pressure chamber 4 formed in the housing 10 . Likewise, a second annular piston 3 is provided, which is also linearly displaceable along the axis A in the second pressure chamber 5 formed in the housing 10 . The first annular piston 2 carries a first sealing ring 13 at the first end 11 . Likewise, the second annular piston 3 carries a second sealing ring 14 at the first end 11 . The first sealing ring 13, 14 serves to seal the pressure chamber 4 or 5 so that no pressurized fluid can escape from the system. A first annular actuating bearing 6 is arranged on the second end 12 of the first annular piston 2 . Likewise, a second annular actuating bearing 7 is provided on the second end 12 of the second annular piston 3 . The hous...

Abstract

The invention relates to a clutch slave cylinder (1) having at least one first annular piston (2) in a first pressure chamber (4) formed in a housing (10) linearly movable in the direction of the axis (A); and at least one second annular piston (3) movable along the axis (A) in a second pressure chamber (5) formed in the housing (10) The direction of A) moves linearly. The first annular piston (2) carries a first sealing ring (13) at a first end (11) and a first annular steering bearing (6) at a second end (12). The second annular piston (3) carries a second sealing ring (14) at a first end (11) and a second annular steering bearing (7) at a second end (12). The first annular steering bearing (6) is an angular contact ball bearing, while the second annular steering bearing (7) is a needle bearing.

Description

technical field [0001] The invention relates to a clutch slave cylinder. The clutch slave cylinder includes at least one first annular piston and at least one second annular piston. In this case, the first annular piston is configured displaceably in the direction of the axis A in a first pressure chamber formed in the housing. Likewise, the second annular piston is designed to be linearly displaceable in the direction of the axis A in the second pressure chamber formed in the housing. Here, the first annular piston is provided with a sealing ring at the first end. The first annular piston carries an annular steering bearing at the second end. In this case, the second annular piston is provided with a sealing ring at a first end and carries a second annular actuating bearing at a second end. Background technique [0002] Clutch slave cylinders for double or triple clutches are well known. The clutch slave cylinder serves to be actuated by the clutch master cylinder in o...
