摘要:
To enable prescribed functional values of pressure plate units of motor vehicle friction clutches to be observed with smaller tolerances than hitherto, it is proposed that a housing-spring component initially be pre-assembled from clutch housing (1) and diaphragm spring (7) and that this component be measured together with a master pressing plate. Geometry (diameter 25 and axial height 27) which is optimum for minimum tolerances of a contact bevel 15 is calculated by means of the measured result, and a pressing plate (13) with this bevel geometry is produced. The measured spring-housing component is finally assembled together with this specially produced pressing palte 913).

The present invention relates to a device for the vibration-reducing transmission of torques between two shaft sections in a shaft arrangement comprising two transmission parts that interact in a torque-transmitting manner in a coupling area, wherein each of the transmission parts has a protruding claw formation, which is received in a receiving area for the transmission of torque from the respectively other transmission part, wherein a damping device is provided between the transmission parts, wherein each of the transmission parts also has a closed bearing ring with a bearing opening, which receives and supports an axial positioning pin, and wherein the bearing ring is integrally connected to the associated claw formation of the respective transmission part and extends axially into the receiving area.
摘要:
In a flexible disk (10) made of rubber-elastic material and having a central axis (A) at least two first and two second connection bodies (32, 34) are inserted alternately, with their own axis (B) parallel to the central axis (A), around the axis (A), at angular distances from one another; they are intended to be fastened each to one of the shaft ends. Flexible inserts (20) are moreover embedded in the flexible disk (10) and extend around adjacent connection bodies (32, 34). For effecting the mutual centring of the two shaft ends a centring device (40) is provided, which comprises a first and a second end plate (22, 24), which are arranged centred in relation to one another each against one end face (12, 14) of the flexible disk (10) and are pivotable about a joint centre (C) lying on the central axis (A). Independently of their subsequent fastening to the first and/or second shaft end the first connection bodies (32) are fastened to the first end plate (22)and the second connection bodies (34) to the second end plate (24) rigidly and securely against rotation.

Centering device for the mutual centering of two shaft ends Two shaft ends (10, 20), which are in torque-transmitting connection with one another and are to a limited extent axially displaceable, rotatable and deflectable with respect to one another, are mutually centered by a stud (36), which extends axially from a first of the two shaft ends (10), and a bearing (40), which is arranged in a cavity (28) of the second shaft end (20) in the cavity (28) and receives the stud (36). The bearing (40) is composed of a central liner (42), in which the stud (36) is supported for the limited relative axial displacements and rotations of the two shaft ends (10, 20), a resilient centering socket (50), into which the liner (42) is embedded in such a manner that it accommodates relative deflections of the shaft ends (10, 20), and a ring-shaped sealing lip (52), which sealingly surrounds the stud (36) and together with the stud and the liner (42) delimits an annular lubricant space (66) on the side of the liner (42) facing the first shaft end (10). The stud (36) is, adjacent its end, encompassed by a second ring-shaped sealing lip (56), which together with the stud and the liner (42), on its side facing away from the first shaft end (10), delimits a second annular lubricant space (68). The cavity (28) is otherwise free from lubricant.
