Problems solved by technology

However, if the liquid film between the sliding surfaces breaks down, this leads to increased friction and thus undesired driving noises, which lead to a reduction in the service life of the slave cylinder and also to a reduction in driving comfort

Embodiment Construction

[0011] exist figure 1 The axis of rotation X, which coincides with the axis of rotation of the slave cylinder 20, is used simultaneously to describe the slave cylinder in two disengaged states. The slave cylinder 20 is thus shown above the axis of rotation X in a position of maximum disengagement and below the axis of rotation X correspondingly in a position of minimum disengagement. This slave cylinder 20 is arranged concentrically around the schematically indicated transmission input shaft 1 configured as a hollow shaft, which has two different diameters directly adjoining each other in the area of ​​receiving the slave cylinder 20 , whereby the A sudden jump from one diameter to another forms a step. On this transmission input shaft 1 , a rolling bearing 1 a and a radial shaft sealing ring 2 a are arranged at a distance from one another, wherein the outer ring of the rolling bearing 1 a and the radial shaft sealing ring 2 a are each supported on the bearing flange 2 via th...

Abstract

A slave cylinder inside a hydraulic section for clutch actuation. The slave cylinder is arranged concentrically about a transmission input shaft in the region of two different diameters that come in direct contact with each other. In order to create a slave cylinder with a compact design, despite unfavorable space conditions, the ratio of 2:1 between the mean housing diameter and the necessary guide length can be implemented, both the inner surface of the housing directed toward the transmission input shaft and the piston are congruent in the longitudinal section with the outer shape of the stepped transmission input shaft such that the piston is guided in the housing at the inside diameter on the clutch-side end and at the outside diameter on the transmission-side end.

Description

technical field [0001] The invention relates to a slave cylinder in a hydraulic section for actuating a clutch having the features of the preamble of claim 1 , which is arranged concentrically around a transmission input shaft. Background technique [0002] Such a slave cylinder is known, for example, from DE 10 2007 023 A1. In this case, an annular piston guided in the housing on the inner shell surface of the housing and loaded with pressure is moved axially in order to move the bearing ring of the release bearing fastened on the end face of the annular piston in the direction of the clutch or Move out of the clutch. This solution involves increasing the service life by lubricating the sliding or guiding surfaces. In order to guide the piston with a high load-bearing ratio on the guide surface during its disengagement stroke, the guide length of the annular piston depends on the inner diameter of the housing, which forms the guide diameter. In practice, a ratio of avera...
