Description
Technical field
The present invention relates to a kind of clutch slave cylinders.Clutch slave cylinder includes at least one first annular piston and at least
One the second annular piston.Here, first annular piston can be along the side of axis A in constituting First pressure chamber in the housing
To movably constituting.Similarly, the second annular piston can be along the direction of axis A in constituting second pressure chamber in the housing
Constitute to linear movement.Here, first annular piston is equipped with sealing ring at first end.First annular piston is in the second end
Place carries annular control lever shaft and holds.Here, the second annular piston is equipped with sealing ring at first end and holds at the second end
Carry the second annular manipulation bearing.
Background technique
Clutch slave cylinder for double clutch or triple clutches is well-known.Clutch slave cylinder is used for,
The clutch slave cylinder is manipulated by clutch master cylinder, so as to the engagement or separation system of controlled clutch.
10 2,016 219 684 A1 of German laid-open document DE discloses a kind of dynamic for bonding and or separation motor vehicle
The steerable system of the clutch of power power train.Clutch slave cylinder disclosed herein is suitable for there are two double clutch and tools
Cylinder, carrying manipulates bearing to described two cylinders at one end respectively.Here, manipulation bearing is respectively structured as annular angular contact ball
Bearing.
10 2,015 208 385 A1 of German laid-open document DE discloses a kind of multiple clutch device of the wet type for vehicle
It sets and torque transmitter.Connector is for manipulating each clutch element and by means of bearing or rolling bearing with can be opposite
It is installed in the mode of transmission input shaft rotation.Connector is a part of engagement device or central engagement device, described to connect
It attaches together and sets or central engagement device is especially constituted in a manner of hydraulic action.Preferably, it is (driven with one heart to be configured to CSC for connector
Cylinder) connector, the CSC connector preferably constituted annular piston.One or more annular pistons are herein by means of corner connection
The operating element that ball bearing is touched relative to clutch supports.
The shortcomings that angular contact ball bearing used in slave cylinder is: the angular contact ball bearing is expensive and needs certain
Structure space.Another feasibility is: the angular contact ball bearing of the prior art is replaced with needle bearing.Needle bearing is obviously more just
Preferably and need smaller axial arrangement space.However, the problem of needle bearing is, radial force and shake can not be absorbed.
Summary of the invention
The object of the present invention is to provide a kind of clutch slave cylinder, the clutch slave cylinder needs a small amount of structure empty
Between, the shake of clutch or clutch slave cylinder is prevented, and constitute at low cost herein.
The purpose is realized by a kind of clutch slave cylinder.
Clutch slave cylinder according to the present invention includes that at least one first annular piston and at least one second annular are living
Plug.Here, first annular piston can movably be constituted in constituting First pressure chamber in the housing along the direction of axis A.
Similarly, the second annular piston can movably be constituted in constituting second pressure chamber in the housing along the direction of axis A.?
This, first annular piston carries sealing ring at first end and carries first annular manipulation bearing at the second end.Together
Sample, the second annular piston carries sealing ring and the second annular of carrying manipulation bearing at the second end at first end.
Here, according to the present invention, first annular manipulation bearing is angular contact ball bearing, and the second annular manipulation bearing is needle bearing.
The support with bourrelet is equipped at the second end of the second annular piston.Therefore, by bourrelet by needle roller
Bearing is felt relieved about axis A.
The second annular piston in second pressure chamber is configured to the annular piston of no guidance.This is indicated: therefore the second annular
Piston has gap clutch slave cylinder in the radial direction.Here, the sealing at the first end of the second annular piston
It is equipped at least one slip ring.Therefore, by slip ring it is possible that: the second annular piston can guide in second pressure chamber.
In order to make the shake of clutch or clutch pressurized tank manipulate bearing not to be configured to needle bearing second
With influence, needle bearing must have the support of the fixation of annular at the second annular piston.It is realized by fixed support
Enough centering of the needle bearing about the axis of clutch slave cylinder.On the contrary, the second annular piston can not about clutch from
The shell centering of dynamic cylinder (CSC).Therefore, it by the design scheme, realizes and lives in the shell of clutch slave cylinder and the second manipulation
Jitter compensation between plug.Jitter compensation does not act on needle bearing as a result,.
Can be for realizing another feasible design scheme of jitter compensation: the second annular piston being capable of structure in two style
At.The two-piece type of second annular piston for example can be realized for example by hinge.
The sealing ring at first end in order to make the second annular piston withstands jitter motion, can be living in the second annular
Additional slip ring or sealing ring carrier are added in the region of the second end of plug.
One advantageous design scheme of the needle bearing used in clutch slave cylinder according to the present invention can be:
Multiple centring elements are equipped between the retainer and outer ring of needle bearing.Similarly, in the retainer of needle bearing and inner ring
Between be equipped with multiple second centring elements.
According to another feasible embodiment, the first centring element can with outer ring or contact surface corresponding with retainer
Place, which is constituted, at least one protrusion.Similarly, the second centring element being capable of corresponding contact between inner ring and retainer
Constituting at face has at least one protrusion.
The centring element has the advantage, that and generates on needle bearing during the centring element is supported on manipulation
Radial force, the radial force are generated by the rotational motion of pressurized tank or disk spring.It is arranged between retainer and inner ring
And the centring element being arranged between retainer and outer ring can be made of plastics.Advantageously due to high speed: fixed
Heart element can be made of high performance plastics, such as PTFE, Torlon material or PEK.First centring element and the second centering member
Part can be configured to individual component.It is same it can be considered that: the first centring element and the second centring element are ejected into holding
On frame, so that first centring element and the second centring element and retainer are formed together unified component.
Another advantageous embodiment according to the present invention, the first centring element are constituted and/or second in the form of slip ring
Centring element is constituted in the form of slip ring.
The radial clearance between retainer and inner ring or outer ring should equally be expanded, so that slip ring or first and second are felt relieved
Element is not contacted with inner ring or outer ring always.This has the advantage of: trailing moment can be reduced by the design scheme.
Therefore, the centring element or slip ring design for constituting protrusion are at so that keep frictional dissipation minimum (in optimal cases
Under, it is not contacted at the position, but there is hydrodynamic pressure condition, it is similar to hydrodynamic pressure sleeve).In order to reduce radial force, additionally it is possible to
Vinyl disc is increased on needle bearing.
