Abstract: The invention relates to a wheel bearing unit (1) for a vehicle wheel, comprising a hub element (2, 3, 2?) which has an axially (a) extending cylindrical section (4) to be supported by a bearing arrangement (5) and which has a radially (r) extending flange section (6) for fixing the vehicle wheel and/or a brake disk at a face side (7) of the flange section (6), wherein the bearing arrangement (5) has an outer ring (8). To ensure a firm and cost effective axial connection between the hub element and the outer ring, the invention is characterized in that the outer ring (8) has a radially extending insection (9) at its a outer circumference (10), wherein the axially (a) extending cylindrical section (4) of the hub element (2, 3, 2?) is deformed partially (11) so that a section of it interferes in the insection (9) for axially fixing the hub element (2, 3, 2?) relatively to the outer ring (8). The invention also relates to a method for producing a wheel bearing unit.

Abstract: A screw actuator comprises a housing (1), a screw mechanism (4) with a nut (6) and a screw (5), as well as a motor (7) which is drivingly connected to the screw. The screw (6) is rotatably and translatably supported with respect to the nut (5), which is fixed with respect to the housing (1). The screw engages a translatable, non rotatable actuating head (29) through a swivel connection. The swivel connection comprises a pair of conformed surfaces (41, 42) having a common rotational axis of symmetry which is aligned with the axis of the screw mechanism.

Abstract: A screw actuator, particularly for a brake calliper, comprising a housing (1), a screw mechanism (4) with a screw (6) and a nut (5), one of which is rotatably supported with respect to the housing (1), a motor (7) which is drivingly connected to the screw mechanism (4), a mechanical locking device comprising a pawl member (41) and a rotatable member (42) connected to a rotatable component of the motor (7) and/or the screw mechanism (4), and a mechanical or electromechanical control mechanism for displacing the pawl member (41) between a locking position and a free position. A gear reduction mechanism (20) is provided, one of the gear wheels (42) thereof carries teeth (45) for engaging with the pawl member (41).

Abstract: A screw actuator module which is to be accommodated in a housing (1), comprising a screw mechanism (2) with a nut (3) and a screw (4), a bearing (5) for the rotor of a motor, and a sleeve (6) which is to be supported with respect to the housing. The sleeve (6) carries a bearing (7) by means of which the nut (3) is rotatably supported. Lock means (36, 37) are provided for preventing rotations of the screw (4) with respect to the sleeve (6).
