Abstract: A linear guide for transmitting a torque between a tubular housing, which is defined by a longitudinal axis and rotatable about the longitudinal axis, and a shaft, which is received in the housing and movable in the direction of the axis in relation to the housing, includes a bearing assembly received in the housing for support of the shaft and attached to the housing by swaging a housing portion. The bearing assembly has two bearing members and a set of rolling bodies disposed between the bearing members. One bearing member is constructed as bushing which is retained in the housing and defines a center axis which is oriented out-of-alignment with a normal upon a longitudinal shaft axis, and the other bearing member has a cup-shaped configuration to define a convex surface for support by a surface area of the shaft.

Abstract: In a linear guide for transmitting a torque between a tubular housing, rotatable about a longitudinal axis, and a shaft, received in the housing and movable in the direction of the axis in relation to the housing, a plurality of axial rolling bearings are received in the housing in surrounding relationship to the shaft. The axial rolling bearings are disposed in two radial planes in axial spaced-apart relationship, wherein the axial rolling bearings in each of the two radial planes have each two bearing members and a set of rolling bodies disposed between the bearing members. One bearing member is constructed as bushing retained in the housing and defining a center axis which is shifted parallel at an offset to a normal upon a longitudinal shaft axis, while the other bearing member has a cup-shaped configuration to define a convex surface for support by a surface area of the shaft.

Abstract: An assembly comprised of a brake disk with a hub. Webs which are adjacent to one another in the circumferential direction extend between and are anchored to the brake disk and are attached to the hub. At least two of the webs which are adjacent to one another in the circumferential direction are formed together in one piece, either from a bent section joining the webs or because adjacent segments having respective adjacent webs are attached. The webs absorb stresses between the brake disk and the hub.

Abstract: A shifting arm for transmitting shifting movements is a formed part which is formed without cutting from a thin sheet. It includes a mouth recess in from an edge of the sheet, and stop faces are formed along the edges of the recess and out of the plane of the sheet.

Abstract: A gear shifting drum (2) for a gear shifting device of variable-speed gearboxes for motor vehicles has a curved path (11a to 11c) for guiding an engagement member (13) of the gearshift fork (12a to 12c), wherein the gearshift fork (12a to 12c) is directly connected to a synchronization device. According to the invention, at least one radially outwardly directed wall (9, 10) is arranged on the outer surface area (8) of the gear shifting drum (2) for formation of the curved path (11a to 11c).

Abstract: The invention concerns a radial piston pump comprising a rotating pump shaft having an end portion connected to a rotationally fixed eccentric ring, said radial piston pump further comprising an eccentric bearing arranged on an outer peripheral surface of the eccentric ring, the eccentric bearing comprising a needle roller bushing having radially inward directed flanges between which bearing needle rollers are arranged for rolling, at least one pump plunger arranged in a pump housing and extending radially of the pump shaft being supported by an end face on the needle roller bushing, while the end portion of the pump shaft is supported in a housing via an adjacent second support bearing.

Abstract: The invention relates to a rocker arm (1) of a valve train of an internal combustion engine. This rocker arm (1) comprises two longitudinally extending side walls (2, 3) which enclose an intermediate space (16) while being connected to each other by a crossbeam (4) to form a U-shaped cross-section. According to the invention, a separate channel (24) for the transport of lubricant is created on a top surface (22) of the crossbeam (4). This channel (24) starts from an abutment (9) for an end of a push rod on the undersurface (8) of the crossbeam (4) and leads to a support (12) for an end of a gas exchange valve in the region of a second end (11) of the crossbeam (4).

Abstract: A method for making a trunnion for a rocker arm or a finger lever of an internal combustion engine from a piece of rod-shaped ground stock by removal of a peripheral section to produce a flat bearing surface including forming the round stock into a barrel-shaped blank by upsetting, shaping the barrel-shaped blank into a rotationally symmetrical element including a central shoulder having a uniform diameter which is greater than the diameter of the trunnion and removing the peripheral section at any point from the central shoulder by shearing from two sides thereof in an axial direction of the rotationally symmetrical element whereby any cutting plane material from the central shoulder is directed towards a sheared surface whereby the bearing surface is a hardened surface.

Abstract: In a zero-clearance radial ball bearing, two outer bearing race sections (4, 5) made by non-cutting methods together support an outer race (2) while between it and a concentric inner race (3) run bearing balls (1). Against the first bearing race section (4) bears a sleeve section (7) which circumferentially and axially surrounds the second race section (5). A spring component (10) pressing the two race section (4, 5) together acts between the sleeve section (7) and the second bearing race sections (5) in such a way that the balls (1) run with zero clearance. In order to improve the rigidity of such a radial ball bearing and especially the sleeve section (7), it is proposed that the two axial ends of the sleeve section (7) project axially beyond the balls (1).

Abstract: A bearing (1) for the wheel suspension strut of a motor vehicle has an inner and an outer bearing ring (2, 3). The inner bearing ring (2) radially encloses a clearance ring (5) concentrically arranged in its bore (4). A bearing housing (8) made of deep-drawn sheet metal encloses the outer bearing ring (3). In order to reduce the total mass of the bearing and to allow it to be easily linked to a neighboring part of the car body, the bearing housing (8) forms a single piece with a flange (9) that extends essentially transversely to the bearing axis (10). The flange has at least one bore and screw (12, 13) for securing the suspension strut bearing (1) to a neighboring part of the car body.
