Embodiment Construction

[0055] exist figure 1 shows a secondary cylinder 1 according to the invention according to a preferred embodiment. In particular, the connection between the (first) piston unit 3 of the auxiliary cylinder 1 and the carrier element 6 can be seen in the figure, which is described in detail below. The auxiliary cylinder 1 is designed as a hydraulic auxiliary cylinder 1 . The secondary cylinder 1 is realized in particular as a multi-separator. The secondary cylinder 1 therefore has, in addition to the (first) piston unit 3 , a further (second) piston unit 16 , wherein each piston unit 3 , 16 serves to actuate a separate clutch. The auxiliary cylinder 1 is thus realized in a typical manner for actuating several clutches or for actuating several partial clutches of a double or triple clutch. During operation, auxiliary cylinder 1 is typically a component of a clutch actuation system of the drive train of the motor vehicle, which is not further illustrated here for the sake of cla...

Abstract

The invention relates to a slave cylinder (1) for a clutch actuating device of a motor vehicle. The slave cylinder comprises a housing (2), a piston unit (3) which has a plurality of individual pistons (4a, 4b, 4c) accommodated in the housing (2) and which, during operation, acts in an adjustable manner on an actuating bearing (5), and the slave cylinder has a carrier element (6) which couples theindividual pistons (4 a, 4 b, 4 c) to the actuating bearing (5), each individual piston (4a, 4b, 4c) being supported in a rotationally fixed manner by means of contact regions (7a, 7b, 7c) on matingcontact regions (8a, 8b, 8c) on the carrier element (6), wherein the two individual pistons (4b, 4c) are arranged with their contact areas (7b, 7c) so as to be relatively displaceable at least in theradial direction relative to the mating contact areas (8b, 8c) of the carrier element (6). The invention also relates to an actuating device having the slave cylinder (1) and to a clutch system.

Description

technical field [0001] The invention relates to an auxiliary cylinder for a clutch operating device of a motor vehicle such as a PKW, LKW, bus or other commercial vehicles, the auxiliary cylinder has: a housing; a piston unit with a plurality of a single piston that acts on the steering bearing in an adjustable manner during operation; and a carrier element that couples the single piston to the steering bearing, wherein each single piston is supported on the carrier element by means of a contact area that is non-displaceable. on the contact area. The auxiliary cylinder with three individual pistons is thus implemented as a multi-piston separator with different individual pistons. The invention also relates to an actuating device for a clutch of a motor vehicle, which has the auxiliary cylinder, and to a clutch system for a drive train of a motor vehicle, which has the actuating device. Background technique [0002] Such auxiliary cylinders and clutch actuation systems are ...
