Definitions
- the invention relates to a release device for a drawn clutch, comprising a release housing and a release bearing with a bearing outer ring and a bearing inner ring, wherein the bearing outer ring is fixed to the Aus Wegergeophuse and the bearing inner ring comprises means for Switzerlandbeaufschlagung a plate spring for clutch actuation.
- a release device with a device for compensating for inaccuracies in a friction clutch of a motor vehicle in which a first device causes a compensation of the inclination of the central axis of the friction clutch to the central axis of the guide sleeve and a second device the Compensation of an offset of the axes is used.
- the second device consists of a sliding surface between the release bearing and the sliding sleeve in a plane perpendicular to the axis of the guide sleeve, wherein the release bearing on this sliding surface relative to the sliding sleeve can be moved within certain limits from its coaxial position to the guide sleeve.
- a clamp connects the release bearing with a sliding sleeve.
- the clip is a sheet metal part and surrounds the bearing outer ring of the release bearing and a mounting flange of the sleeve.
- An object of the invention is therefore to provide a clutch release device which is simpler to manufacture and, in particular, also easier to assemble, for a pulled clutch. provide, which causes a compensation of the axial offset between the rotational axis of the release bearing and the central axis of the releaser.
- a release device for a drawn clutch comprising a - release housing and a release bearing with a bearing outer ring and a bearing inner ring, wherein the bearing outer ring is fixed to the Ausschreibergephaseuse and the bearing inner ring means for Switzerlandbeaufschlagung a plate spring for clutch actuation, wherein parts of the bearing outer ring engage behind a trained as a plate part of the Ausschreibergeophuses radial play, and wherein a spring element between the bearing outer ring and the Aus Wegergephaseuse is arranged, which acts on the bearing outer ring in the axial direction with a biasing force against the Ausschreibergephaseuse.
- the releaser is essentially a rotationally symmetrical component, the central axis corresponding to the axis of symmetry. Essentially, it is meant here that the releaser may deviate in some areas from the rotationally symmetrical structure, in particular in order to provide fastening means or the like.
- the housing of the releaser is no longer in contact with the outer circumference of the outer ring of the release bearing. The housing is therefore provided with a smaller outer diameter than the inner diameter of the housing part, which surrounds the housing of the clutch release.
- the spring element is designed as a plate spring biasing spring, which is supported with a radially outer portion of the bearing outer ring and with a radially inner portion of the Ausgurergephaseuse.
- the plate spring causes a bias of the outer ring of the release bearing relative to the housing of the releaser in the axial direction, so that no axial play between the two occurs.
- the biasing direction is the opposite direction to the disengaging direction, therefore, the plate spring is not loaded when disengaging the clutch.
- the diaphragm spring thus brings no additional spring stiffness in the system in the release direction.
- the diaphragm spring is preferably located with its outer diameter on an inner diameter of the bearing outer ring of the release bearing, wherein the bearing outer ring in this area has a substantially radially extending contact surface against which abuts the outer region of the plate spring.
- the plate spring is thus centered by the bearing outer ring of the release bearing in the radial direction. This has the advantage over a centering on the inner circumference of the plate spring that no radial play against the bearing outer ring is present, which at sufficiently large radial offset to a Canting the plate spring could lead to the inner diameter of the radially extending contact surface for the plate spring.
- the parts of the bearing outer ring which engage behind a trained as a plate part of the Aus Wegergeophuses radially play, a locking ring.
- the circlip is a spring-loaded ring that is opened in one place so that the ring can be squeezed together for mounting.
- Such circlips are also z. B. known as snap rings.
- the retaining ring is arranged in a circumferential radial groove of the bearing outer ring.
- the circumferential radial groove is in the circumferential direction on the inside of the part of the bearing outer ring, which engages behind the housing part of the Ausgurergephinuses radially play, introduced.
- the groove ensures axial and radial fixing of the retaining ring in the installed position.
- the parts of the bearing outer ring which engage radially behind a housing part of the release housing with play, comprise an intermediate ring.
- the bending forces acting on the locking ring can be so great that it could be deformed in the manner of a disc spring and so out of the groove in which the retaining ring is fixed, could be pushed out.
- the intermediate ring is in several parts. Due to the multi-part design, the assembly is facilitated, otherwise the intermediate ring must be provided at one point with an opening, so that the intermediate ring can be bent up for mounting. The multi-part design thus facilitates the assembly of the intermediate ring.
- the housing part which is engaged behind play of parts of the bearing outer ring, the at least partially in the circumferential direction of the release housing extending plate.
- a plate which extends in the radial direction and is rotationally symmetrical in the circumferential direction is called a plate. stood, whose two faces are radial and flat. Under end faces are understood in a sectional view axially facing the release bearing or facing away sides.
- the plate spring is supported for biasing the release bearing against the Aus Wegergetude from, on the other side, the intermediate ring or retaining ring is supported.
- the bearing outer ring comprises a hollow cylindrical portion which covers the plate with play.
- the hollow cylindrical area completely covers the plate in the installed position and carries the circumferential radial groove for receiving the retaining ring.
- the plate spring acts on the bearing outer ring in the axial direction with a biasing force, which causes a concern of the intermediate ring on the plate and a concern of the retaining ring on the intermediate ring.
- the preload force ensures that when unloaded clutch release, this corresponds to the engaged position of the clutch, no play between the Ausgurergetude and the bearing outer ring of the release bearing is formed. As a result, axial vibrations that could run the entire release bearing in a game against the release housing, prevented.
- the means for Switzerlandbeetzstoff the plate spring for clutch actuation is an at least partially circumferential in the circumferential direction nose with which an indirect or immediate positive connection with the diaphragm spring is produced.
- Figure 1 shows an embodiment of a Kupplungsaus Wegers invention in a sectional view.
- the clutch release 1 comprises a release housing 2 and a release bearing 3.
- the release bearing 3 comprises a bearing outer ring 4 and a bearing inner ring 5.
- the bearing insert nenring has a in the axial direction extending from the Aus Wegergeophuse 2 away hollow cylindrical extension 6, which has a circumferential nose 7 at its axial end.
- the circumferential nose 7 is formed by a conical bevel 8 and a substantially radially extending edge 9.
- the circumferential nose 7 makes it possible with a contact plate 10, which has a disc-shaped opening and in the radial direction is elastic or divided into two parts for mounting, to enter a positive connection in the manner of a snap connection.
- the contact plate 10 is in the installed position of the clutch release 1 in contact with a disc spring, not shown in Figure 1 for clutch actuation, wherein it is a so-called pulled clutch, the disc spring is in contact with the provided with the reference numeral 11 back of the Contact plate 10 and is raised by a movement of the clutch release 1 in the direction of arrow 12.
- the bearing outer ring 4 of the release bearing 3 has a substantially hollow cylindrical extension 13, which covers a formed on the release housing 2 plate 14. Between the plate 14 and the extension 13 is a radial clearance s1, which allows a radial relative movement of the release bearing 3 relative to the release housing 2.
- the release housing 2 has an inner ring 15, which extends in the axial direction radially inside the bearing inner ring 5. Between the bearing inner ring 5 and the inner ring 15 also remains a game s2, which is equal to the game s1 and may be larger than the game s1.
- the preload spring 21 is a plate spring.
- the preload spring 21 is arranged so that the radially outer region projects in the axial direction towards the release bearing 3 with respect to the radially inner region. With its outer circumference, the preload spring 21 bears against the inner circumference of the hollow cylindrical extension 13.
- the transition of the hollow cylindrical extension 13 to the remaining region of the bearing outer ring 14 forms a step, so that a contact surface 22 for the preload spring 21 is formed. In its inner region, the preload spring 21 bears against a contact surface 23 of the plate 14 formed on the release housing 2.
- the preload spring 21 is therefore centered on its outer circumference by the inner circumference of the extension 13.
- the preload spring 21 pushes the bearing outer ring 4 away from the release housing 2 in the axial direction. This ensures that the bearing outer ring 4 and thus the entire release bearing 3 is secured without play on the release housing 2.
- the application of force ensures that a radial relative movement of the release bearing 3 relative to the release housing 2 only under Overcoming a frictional force between the contact surfaces 22 and 23 and the preload spring 21 applied there can take place. As a result, axial movements of the release bearing 3 with respect to the release housing 2 are damped by dry friction.
- the extension 13 comprises a circumferential groove 16, in which a securing ring 17 is arranged in the manner of a snap ring. Between the locking ring 17 and the plate 14, a two-piece intermediate ring 18 is arranged.
- the intermediate ring 18 is, as can not be seen in the drawing of Figure 1, divided into two circumferentially, so it consists of two half rings.
- the intermediate ring 18 could also have a slot similar to the locking ring 17, which allows bending or pressing of the intermediate ring 18 and thus would allow a mounting similar to a snap ring.
- a sliding bush 19 is arranged.
- the release housing 2 has a stepped bore, so that the slide bushing 19 abuts against a circumferential edge on the side facing the release bearing 3.
- a locking ring 20 is arranged in a circumferential groove which fixes the sliding bush 19 in the axial direction.
- the assembly of the clutch release 1 according to the invention is done in the following order: First, the preload spring 21 is inserted into the bearing 3. In the next step, the retaining ring 17 is joined over the housing 2. For this purpose, the retaining ring 17 is slightly bent apart and pushed over the plate 14. In the next step, the housing 2 is placed on the bearing and the preload spring 21 is pressed in by pressure, so that the release housing 2 is pressed as far as possible into the release bearing 3. The plate spring 21 is brought into a flat position, so it is virtually flat on the entire area of the plate 14 of the housing 2 at. Now the two half rings of the intermediate ring 18 are placed. In the next step, the retaining ring 17 is inserted into the circumferential groove of the bearing outer ring 4.
