Embodiment Construction

[0026] The drawings are merely schematic in nature and are used only to aid in the understanding of the invention. Identical elements are provided with the same reference numerals. Features of different embodiments can also be freely combined with one another.

[0027] figure 1 The structure of the concentric slave cylinder 1 (CSC / "Concentric Slave Cylinder-concentric slave cylinder") of the present invention is shown. The slave cylinder 1 implemented according to the first embodiment is designed as a double slave cylinder. The slave cylinder 1 is thus used in operation to actuate two clutches of the motor vehicle drivetrain, for example two partial clutches of a dual clutch. The slave cylinder 1 is implemented in the form of a hydraulic slave cylinder 1 . The slave cylinder 1 is implemented as a concentric slave cylinder 1 . Accordingly, the slave cylinder 1 has an annular extension / design as a whole. During operation, the slave cylinder 1 is an integral part of the cl...

Abstract

The invention relates to a slave cylinder (1) for a clutch actuation device of a motor vehicle, comprising a multipart housing (3), which extends concentrically about a longitudinal axis (2), and at least one piston (5) which is received in the housing (3) in a movable manner and which together with the housing (3) delimits a pressure chamber (4), wherein the housing (3) is provided with a coolantchannel (6) which runs at least partly in a radial direction, and the housing (3) has a first housing component (7), which consists of plastic, and a second housing component (8), which is connectedto the first housing component (7) and consists of a metal material. The coolant channel (6) is formed at least partly by the first housing component (7). The invention additionally relates to a clutch actuation device comprising said slave cylinder (1).

Description

technical field [0001] The present invention relates to a slave cylinder suitable for a clutch operating device of a motor vehicle such as a passenger car, truck, bus or other commercial vehicle, comprising a multi-piece housing extending concentrically around a longitudinal axis and at least one movable A piston accommodated in the housing and delimiting a pressure chamber together with the housing, wherein the housing is provided with a coolant channel extending at least partially in the radial direction (of the longitudinal axis). In addition, the present invention also relates to a clutch operating device including such a slave cylinder. Background technique [0002] applicants by pressing Figure 5 The illustrated implementation of the slave cylinder 1' understands such background art. The slave cylinder 1' has a coolant channel 6' in a housing 3' made of metal, which is relatively expensive to manufacture. exist Figure 5 Among them, the coolant channel 6' is formed ...
