Definitions
- the invention relates to a slave cylinder within a hydraulic line for clutch actuation, which is arranged concentrically about a transmission input shaft, having the features of the preamble of claim 1.
- Such a slave cylinder is known for example from DE 10 2007 023 A1.
- a guided in the housing at its inner circumferential surface and pressurized annular piston is axially displaced to move a bearing ring of a bearing on the end face release bearing either in the direction of coupling or away from it.
- This solution is about increasing the service life by lubricating the running or guiding surfaces.
- the guide length of the annular piston depends on the inner diameter of the housing, which forms the guide diameter. It is common in practice, the ratio of average housing diameter to required guide length of 2: 1 comply.
- a slave cylinder which solves this problem by the piston is formed of two concentric nested pistons and thus the guide length is axially telescopically extendable.
- the guide length is axially telescopically extendable.
- a slave cylinder with an axial expansion having a hollow cylindrical housing which is open on the clutch side and is limited at the transmission-side end of a running in the radial direction approach.
- an annular piston is axially displaceable, which, like the housing, is arranged concentrically about a rotation axis having a transmission input shaft. Due to the fact that in the region of the receiving of the slave cylinder, the transmission input shaft has two directly meeting different diameters, both the transmission input shaft directed to the inner surface of the housing and the piston are formed congruent in longitudinal section to the outer shape of the transmission input shaft, wherein the piston on the coupling end its inner diameter and the transmission-side end is guided at its outer diameter in the housing.
- Figure 1 shows a partial section through a concentrically arranged around a transmission input shaft slave cylinder
- the axis of rotation X which coincides with the axis of rotation of a slave cylinder 20, simultaneously used to represent this in two Ausgurzusayn.
- the slave cylinder 20 is shown above the axis of rotation X in maximum and below the axis of rotation X corresponding to a minimum disengaged position.
- This slave cylinder 20 is concentrically arranged around an indicated, designed as a hollow shaft, transmission input shaft 1, which has two directly meeting each other in the region of the receiving of the slave cylinder 20 different diameter, so that by the sudden jump of a Diameter to the other one step is formed.
- a roller bearing 1 a and a radial shaft sealing ring 2 a are arranged at a distance from each other, the outer ring of the rolling bearing 1 a and the radial shaft sealing ring 2 a being respectively supported by the outer surface of its housing on a bearing flange 2, which is connected to a coupling bell, not shown.
- a snap ring 2b inserted into the coupling-side end region of the bearing flange 2, the inner ring of the rolling bearing 2a is positioned in position.
- the shape of the bearing flange 2 is adapted to the stepped transmission input shaft 1. In addition, it has a projection 2c in the radial direction.
- a further roller bearing 1b is provided for supporting or supporting the transmission input shaft 1.
- cup-shaped bearing flange 2 of the inner shape of this bearing flange 2 adapted housing 3 of a concentrically arranged around the transmission input shaft 1 slave cylinder (CSC) is inserted.
- the direction of the transmission input shaft 1 inner surface of the housing 3 is adapted with its axial extent to the step shape of the transmission input shaft 1 so that it is divided as a result of the stage in two axial regions A and B.
- a line 17 can be seen, from which it can be seen that the CSC has a hydraulic connection.
- This line 17 is inserted into the housing 3 by means of a plug 5.
- the plug 5 is fixed by means of an O-ring 5a and a securing element in the form of a wire-shaped spring 5b both in the receiving bore of the housing 3 and sealed. With the help of a sealing plug 3a, the production-related bore of the inlet is closed.
- the housing 3 of the CSC is divided radially parallel to the axis of rotation X of the transmission input shaft 1 by a wall 3b in two functional areas.
- the first inner serves to receive an axially movable piston 7, while the outer functional area for mounting the housing 3 on the bearing flange, which is visible from the sectional view below the axis of rotation X by a mounting screw 4.
- the pot-shaped region thus has an inner diameter Dl and an outer diameter DA.
- the space formed between these two diameters DA and Dl limits a pressure chamber in the radial direction. In the axial direction of this is bounded by the piston 7 and the clutch-side inner surface of the neck 2c.
- the retracted wall 3b in the housing forms over its axial length a region C, whose inner surface serves as a guide surface, so that the means of an energy storage in the form of a preload spring pressurized annular piston 7 both with its inner and with its outer diameter and thus in Area A and at the same time in the area C of the housing is guided on a guide surface.
- This will - A - avoided edges of the piston 7 during its axial movement.
- the region B of the housing 3 serves to receive the energy accumulator 12, whose end turns are respectively supported on the piston 7 and on the projection 2c.
- the piston 7 has for sealing the pressure chamber on the inner circumference of a trained as innener.Nutdichtring sealing element 10 and on the outer periphery of a formed as an outer groove sealing ring sealing element 11.
- a release bearing 15 is connected to the piston 7, the inner ring is in operative connection with a plate spring 16 only indicated in the figure.
- Both the inner diameter and the outer diameter of the piston 7 is provided to improve the sliding movement with guide belts 8 and 9, via which the piston 7 is in direct contact with the surrounding guide surfaces.
- the annular piston 7 is also formed in a stepped manner in longitudinal section from the difference of the distance between the two guide belts 8 and 9.
