Definitions
- the invention relates to a clutch assembly for connecting a drive to a unit of a motor vehicle.
- the unit can be, for example, a compressor or a retarder.
- the drive of such units is not required during the entire operation, so that it is already known from the prior art to arrange a clutch between the drive and the unit.
- the power transmission in switchable clutches usually takes place via friction linings that are only designed for a certain number of switching cycles.
- safety-relevant auxiliary units such as the air compressor in motor vehicles, which provides compressed air for the service brake system, a clutch connected between the drive and the unit must not fail.
- a conical friction clutch is known, which is moved into the operating position by means of a spring element and can be switched into a disengagement position by means of the actuating element.
- Another coupling device is known from DE102019135350 B1.
- the essential clutch components are the friction linings, which are subject to wear. To ensure the function of the auxiliary unit, the clutch must be in the closed position when the clutch is not engaged.
- a locking element is proposed which prevents the clutch from slipping in the event of excessive wear.
- the clutch devices can be dismantled, for example to replace the friction linings. The fitter is then responsible for correctly setting the switching forces and/or switching travels, which can lead to incorrect settings.
- the object of the invention is to propose a clutch assembly for coupling a drive train to a unit that ensures safe operation.
- the object is achieved according to the invention by an embodiment according to the independent claim. Further advantageous embodiments of the present invention can be found in the subclaims.
- a clutch assembly for coupling a drive with a unit of a motor vehicle which comprises a housing in which an inner ring, a friction lining, a spring assembly and a bearing are arranged, wherein in an operating position of the inner ring a friction connection is established between the inner ring by means of the spring force of the spring assembly , friction lining and housing can be produced and the inner ring can be moved axially into a disengagement position in which the housing is rotatably mounted relative to the inner ring via the bearing.
- the housing is designed in two parts and is composed of an outer ring and an outer ring carrier, the outer ring and the outer ring carrier being designed such that the inner ring, the friction lining, the spring assembly and the bearing are fixed in the housing after the housing has been assembled.
- This design allows the clutch assembly to be assembled in advance and mounted as a unit on a shaft of a unit. By fixedly setting the spring forces, tight tolerances can be guaranteed, which improves functional reliability.
- the outer ring and the outer ring carrier can also be permanently connected after assembly. This can be done, for example, by welding, gluing or another permanent connection.
- the inner ring is coupled in a rotationally fixed manner to an intermediate sleeve, e.g.
- the intermediate sleeve having internal teeth which are designed in such a way that the intermediate sleeve is axially movable on a shaft with counter-toothing.
- the torque is transferred from the clutch to the unit via the gearing.
- the axial displaceability ensures movement from the operating position to the disengaged position, idle.
- the bearing can consist of a shaft sleeve on which a collar bushing is mounted and an axial bearing which is arranged between the spring assembly and the outer ring carrier, the shaft sleeve being designed in such a way that it is axially displaceable on a shaft journal.
- the friction lining can be applied to the inner ring, which can be brought into contact with an inner surface on the outer ring.
- a friction lining applied to the inner surface of the outer ring or friction rings applied on both sides is also conceivable.
- a unit with a corresponding clutch assembly is proposed, wherein the clutch assembly can be pushed onto a drive shaft of the unit and an axial position of the clutch assembly relative to the unit can be adjusted by means of a stop.
- the stop can be a stop nut or clamping nut that can be screwed onto the shaft journal.
- the unit also includes an actuator by means of which the inner ring can be moved in the axial direction against the spring assembly into the disengaged position.
- FIG. 1 This shows the sectional view through a clutch assembly 1 according to the invention.
- the essential clutch components are the inner ring 2 and the outer ring 3, which are mounted so that they can rotate relative to one another in the open position of the clutch shown, so that no torque can be transferred from the outer ring 3 to the inner ring 2.
- the friction lining 4 or clutch lining is arranged between the inner ring 2 and the outer ring 3, File: 26702 WO / AVS, which in the embodiment shown is attached to the inner ring 2 and can be moved against the inner surface 16 of the outer ring 3.
- This general coupling surface arrangement is well known from the prior art.
- the inner ring 2 is connected to the intermediate sleeve 17, welded in this version.
- the space between the intermediate sleeve 17 and the inner ring 2 is designed in such a way that the spring package can be installed there.
- the shaft 12 has internal teeth 5 on which the intermediate sleeve 17 is positioned axially displaceably and radially in a rotationally fixed manner. This ensures torque transmission from the friction lining 4 via the intermediate sleeve 17 to the shaft 12.
- In the front area of the shaft 12 is designed as a shaft journal 18.
- the shaft sleeve 9 is arranged on the shaft journal 18 and axially secured with a clamping nut 14, so that an exact axial position of the shaft sleeve 9 on the shaft journal 18 can be defined, which forms a stop for the intermediate sleeve 17 in the disengaged position.
- the axial displacement of the intermediate sleeve 17 into the disengaged position takes place by means of the actuator 10, which is designed here as a piston 10 and, as known from the StdT, can be actuated pneumatically.
- the working position shown is the disengagement position or decoupling position, in which the piston 10 is pressurized with compressed air, so that an axial force acts on the spring assembly 11 and this is compressed.
- the spring assembly 11 is supported on the axial bearing 7.
- the outer ring carrier 6 is arranged to be freely rotatable on the shaft 12 or the shaft journal 18, the storage being carried out via the collar bushing 8.
- the coupling to the drive is not shown, although the outer ring carrier 6 can be coupled directly to the drive.
- the coupling assembly 1 is an assembly that includes all coupling parts, including the intermediate sleeve 17 and the shaft sleeve 9, which can be pushed onto the shaft 12 or the shaft journal 18.
- the essential external structure of the clutch assembly 1 is formed by the outer ring 3 and the outer ring carrier 6, which are welded together via the weld seam 15, so that a housing for the components 2, 7, 8, 9, 11 and arranged between them 17 is created, which must be assembled before the outer ring 3 and outer ring carrier 6 are assembled and welded and can then no longer be removed.
- the coupling assembly 1 can only be pushed onto the shaft end as a whole, with an axial position of the coupling assembly 1 being able to be determined by means of the clamping nut 14.
