  • Patent number: 5927870
    Abstract: An angular thrust washer (1) for a thrust bearing comprising a radial portion (2) serving as a raceway, said radial portion (2) merging into at least one axially extending angled portion (4), and rotation being prevented by at least one projection which engages a recess (9) of a housing (6) whereby the projection is configured as a flat retention tongue (5) formed integrally on the radial portion (2) and projecting beyond the radial portion (2) in radial direction while being arranged in a plane which is axially offset from the radial portion (2) towards a bottom of the recess (9) which prevents a contact between the shaping radii (12) of the retention tongue (5) and the side walls (10, 11) formed during manufacture and the run-out radii (13) of recess.

  • Patent number: 5921577
    Abstract: A clamping device for a steering column (6) which is guided in fixed mounting arms (4, 5) and comprises a tie bolt (7) which is arranged at right angles to the steering column (6), the tie bolt (7) extends between the two mounting arms (4, 5), there being arranged on one end of the tie bolt (7), between a thrust washer (11a) and the mounting arm (4), a clamping washer (12a) comprising clamping ramps (13a) on which rolling elements (14a) are supported while being guided in a retention disc (15a) mounted for rotation on the tie bolt (7), the retention disc (15a) can be rotated by means of a hand lever (19), and, depending on a direction of rotation of the retention disc (15a), the mounting arms (4, 5) effect a clamping or a releasing of the steering column (6), characterized in that the clamping device (1a) comprises a pot-shaped housing (2) which bears against the mounting arm (4) by a bottom (3) and encloses all the clamping means, the housing (2) is closed at one end by a thrust washer (11a), while the clamp

  • Patent number: 5887688
    Abstract: A synchronizing device (4) comprises a thrust member (10) to initiate synchronization during a gearshifting operation, and the thrust member (10) receives a spherical locking element (12) to lock a sliding sleeve (9) in its neutral position. According to the invention, the thrust member (10) which is made as a one-piece element comprising a foot portion (26) and a head portion (27) receives the locking element (12) and a compression spring (11) in its interior and is displaceable in a T-shaped longitudinal groove (25) of an inner synchronizer ring (5).

  • Patent number: 5335998
    Abstract: An axial beaing unit comprising two bearing discs (1, 2) with rolling elements (3) disposed therebetween, each of the bearing discs (1, 2) comprising an axially oriented cylindrical flange, which cylindrical flanges overlap each other in the axial direction, the flange of one of the bearing discs (1) being made as an overhanging flange (9) comprising a radially projecting end portion (3) at its free end (11), and the flange of the other bearing disc (2) being a retaining flange (10) comprising a retaining surface (14) facing the end portion (13), the end portion (13) engaging behind the retaining surface (14) so that the bearing discs are connected to each other secure against loss, characterized in that the radially projecting end portion (13) comprises several elastically yielding bosses (12) made without chip-removal and arranged spaced apart on the circumference of the end portion (13), which bosses (12) engage as a result of radial elastic relaxation behind the retaining surface (14).

  • Patent number: 5309787
    Abstract: A locking pin, in particular for the securing of shift positions of a shift linkage in automobile transmissions, comprises a hollow cylindrical shaft portion (1) which is drawn from thin-walled sheet metal and closed at one end by a bottom (2). This bottom (2) projects radially beyond the shaft portion (1). A locking element (3) projecting out of the shaft portion (1) at the open end thereof is guided longitudinally displaceable in the shaft portion (1), retained secure against loss und pre-tensioned in the locking direction by a spring (4). To obtain a locking pin which is cost-effective in manufacturing and easily dismountable, a diameter enlargement (7) serving as a stop is provided at a pre-determined distance both from the open end of the shaft portion (1) and from the bottom (2).

  • Patent number: 5114249
    Abstract: An axial rolling bearing comprising a cage containing rolling elements and arranged between two plane-parallel, thin-walled bearing discs made of sheet metal, wherein the three components together form a structural unit by engaging together in a form-locking manner and at least one of the bearing discs merges at one of its peripheral edges into an axially directed collar which engages around the cage with clearance and extends into the region of the second bearing disc characterized in that there is a narrow guiding clearance at at least some peripheral points between the mutually facing peripheral surface of the collar and of the second bearing disc respectively.
