In order to provide a shaft-hub connection which is optimized in particular in regard to the force introduction into the shaft, it is proposed by the invention that the hub seat (2) has at least one radial projection (9, 10) in the longitudinal direction (11) of the shaft (1).

Abstract: The invention relates to a clutch having a first clutch part (2) and a second clutch part (3), wherein said two clutch parts (2, 3) are disposed pivotably relative to one another. In order to propose a clutch which in particular allows a precisely-positioned location fixing of the two clutch parts (2, 3) to one another, a clutch (1) is proposed by the invention which is characterized by a clutch element (4), which can be positioned rotationally-fixed relative to one of the two clutch parts (3), wherein the other of said two clutch parts (2) has a clutch member (6), which works together with a clutch member (7) carried by said clutch element (4).

Abstract: The invention relates to a wheel assembly of a motor vehicle, in particular a passenger car, having a brake disc (3) received by a wheel axle (2) so as to be fixed against rotation and a brake caliper (4) that interacts with the latter and, constructed as a fixed caliper, is arranged on a wheel carrier (5) so as to be fixed with respect to the brake disc (3). The brake disc (3) is carried by the wheel axle (2) such that it is relatively displaceable with respect to the brake caliper (4) in the longitudinal direction (9) of the wheel axle (2).

Abstract: Ball cage for homokinetic joints, formed from a blank that is configured as a substantially annular spherical segment, the ball cage includes: window-type ball pockets located along an equator with substantially equator-parallel bearing surfaces that interact with joint balls, with substantially annular functional zones that are designed at least on outer ring edge areas and that interact with a joint bell, and with substantially annular functional areas that are designed on inner ring areas and interact with the joint spider, wherein on the blank at least some of the functional zones are elevated compared to the neighboring areas of the ball cage.

Abstract: The invention relates to a method for finishing the ball cup of a homocinitic joint, especially for motor vehicles, having a ball ring-shaped bearing surface for the ball cage and a plurality of essentially axial running guideways which interrupt said ball ring-shaped bearing surface. The guideways are provided for the balls which are arranged in the ball recesses of the ball cage and which transmit torque between the ball cup and the ball star. In order to be able to finish such ball shells quickly, economically and as fully automatic as possible, the invention provides that both the ball ring-shaped bearing surface for the ball cage as well as the guideways for the balls are produced by means of a turning machining.

Abstract: The invention relates to a method for finishing the ball star of a homocinetic joint, especially for automobiles. The ball star has a ball ring-shaped bearing surface for mounting in a ball cage, and has a plurality of essentially axial running guideways provided for the balls. Said balls are arranged in the ball recesses of the ball cage and transmit torque between the ball cup and the ball star. In order to be able to finish such ball stars quickly, economically and as fully automatic as possible, the invention provides that both the ring-shaped bearing surface provided for mounting in the ball cage as well as guideways provided for the balls are produced by a hard-rotary turning operation.

Abstract: The invention relates to a process for the finishing of ball cages (1) destined for constant-velocity joints which are provided with spherical annular inner and outer bearing surfaces (3, 2) and ball pockets (4) for the accommodation of torque-transmitting balls. In order that the finishing of such ball cages (1) can be carried out rapidly, at low cost and in as fully automated a manner as possible it is proposed according to the invention that the finishing both of the inner and outer spherical annular bearing surfaces (3, 2) as well as the contact surfaces (5) of the ball pockets (4) located opposite one another in the axial direction and each for one ball ensues by means of lathe machining.

Abstract: The invention relates to a wheel suspension for the driven wheels of a motor vehicle which are each fastened detachably by means of wheel bolts to a contact surface of a brake member which for its part is mounted rotatably by means of at least one roller bearing on a suspension connected in pivotable manner to the frame or structure of the vehicle and is connected to a drive shaft. In order to provide a structurally simple connection which is free of play both in the axial as well as in the radial direction the end of the drive shaft on the wheel side is connected via a shaft section having a polygonal outer contour directly to the brake member. Furthermore the drive shaft adjoining this polygonal shaft section is constructed with a cylindrical shaft section serving as the seat for the roller bearing.

Abstract: The invention concerns a device for infinitely variable support of a tool on a drivable tool spindle of a machine tool. To provide such a device which allows exact adjustment of the tool within a range of one millimetre, at the same time avoiding centrifugal force-related imbalances, it is proposed that the tool is exchangeably attached to a tool carrier which is mounted in a housing so as to be pivotable about an axis of rotation of the tool carrier extending at an angle, preferably at a right angle, to the axis of rotation of the tool spindle.
