Definitions
- the invention relates to a clutch arrangement with an axial adjusting device in the form of a ball ramp arrangement with an axially supported support disk and an axially displaceable thrust washer, which have in their mutually facing end faces spherical grooves with depth varying in opposite directions over the circumference, in which pairs of spherical grooves each run balls over which the support plate and the pressure plate are axially supported on one another and the support plate and the pressure plate can be rotated in relation to one another by motor.
- Coupling arrangements of this type are widely used in drive trains of motor vehicles as locking clutches for differential gears or as so-called hang-on clutches for driving an additional drive axle as required.
- your area of application is not limited to these areas of application.
- the electromotive drive of at least one of the rotatable disks, namely the support disk and thrust washer, generally takes place via a spur gear reduction stage, a transmission ratio of 1:50 being typical. This creates high axial loads for the axial bearings used for support or pressure transmission on the two disks. In addition, extremely high pressure loads arise on the few supporting balls in the ball groove pairs.
- the object of the present invention is to reduce the high loads on the ball ramp arrangement described herewith, without accepting a reduction in the axial adjustment forces on the coupling arrangement.
- the solution to this is that the thrust washer of the ball ramp arrangement acts on a first pressure plate and the clutch arrangement on a second Pressure plate is acted upon and a plate spring is arranged between the first pressure plate and the second pressure plate, the apex of the plate angle facing the first pressure plate and which is axially fixed in the clutch basket on its outer circumference, acts with an intermediate diameter on the second pressure plate and on its inner edge on the first Pressure plate is applied.
- the distance D1 from the outer edge of the plate spring to the intermediate diameter D3 is smaller than the distance D2 from the intermediate diameter D3 to the inner edge of the plate spring, in particular by a multiple smaller. It is further proposed that an annular web is formed on the second pressure plate on the intermediate diameter D3, which is in contact with the plate spring.
- the disc spring rests freely with its inner edge on a radial surface of the first pressure disk. It is proposed that the plate spring is axially fixed with its outer edge between two locking rings fixed in a clutch basket.
- the clutch arrangement used is preferably a multi-plate clutch with a clutch basket and a clutch hub, the plates being alternately connected to the clutch basket and the clutch hub and the disk set being supported on the clutch basket.
- the figure shows a coupling arrangement according to the invention in longitudinal half-section.
- the clutch arrangement 11 comprises a clutch basket 12 and a clutch hub 13, between which a disk set 14 is seated. Outer clutch plates are connected to the clutch basket, inner clutch plates to the clutch hub.
- the clutch arrangement is acted upon axially by an axial adjusting device 21, which comprises a support disk 23, which is supported in a housing 22, and a pressure disk 24, which is axially displaceable.
- the disks 23, 24 have circumferential spherical grooves 25, 26, the depth of which changes in opposite directions in the circumferential direction. Between the pairs of ball grooves 25, 26 there are balls 27, one of which can be seen here.
- the thrust washer 24 is rotatably supported on the clutch hub 13 via a needle bearing 28.
- the support disk 23 is held in the circumferential direction in the housing 22.
- the thrust washer 24 can be driven in rotation via a spur gear 31 which has an intermediate shaft 32 with a double pinion 33, 34 and can be driven by a drive pinion 35.
- the pinion 35 is seated on the output shaft 36 of an electric motor 37.
- the bearing of the intermediate shaft is not shown.
- the axial adjustment device 21 acts via an axial bearing 41 directly on a first pressure plate 42, against which a disc spring 43 rests with its inner circumference.
- the plate spring 43 is supported with its outer circumference by means of two retaining rings 44, 45 in the clutch basket 12.
- a second pressure plate 46 In front of the plate pack 14 is a second pressure plate 46, which has an annular collar 47 on an intermediate diameter near the outer circumference, with which the plate spring 43 is in contact.
- the plate spring 43 which is fixed in the clutch basket 12, acts with great leverage on the annular collar 47 on the second pressure plate 46, so that with larger travel ranges and lower forces on the first pressure plate 42, smaller travel ranges and longer ones Pressure forces are exerted on the second pressure plate 46.
- the ball ramp arrangement 21 is hereby relieved of axial forces, ie in particular the forces on the axial bearing 41 and in the ball grooves 25, 26 are significantly reduced.
- the radial distance D1 from the outer edge of the plate spring to the ring collar is significantly smaller than the radial distance D2 from the ring collar to the inner edge of the plate spring.
