摘要:
A dual clutch which has two friction clutches, which have a central pressure-exerting plate and two pressure plates which are axially movable relative to the pressure-exerting plate with the interposition of the friction linings of two clutch disks, which each mesh with a gearbox input shaft of actuating devices. The pressure plates are acted on by transmission elements by the actuating devices directly without a lever action. Furthermore, for the cooling and lubrication of the actuating bearings between the actuating devices and the transmission elements, an annular chamber can be formed which has an increased fluid volume.

A dual clutch which has two friction clutches, a central pressure-exerting plate and two pressure plates which are axially movable relative to the pressure-exerting plate with the interposition of the friction linings of two clutch disks, which each mesh with in-each case one gearbox input shaft, of actuating devices. The dual clutch is held at the drive-input side, with the dual clutch being supported at the gearbox side by an actuating system, which holds the two actuating devices, for actuating the pressure plates, and with the actuating system being rotatably held on the clutch housing.

A controlled axial biasing unit (1) is provided which substantially includes a first ramp disk (11) and a second ramp disk (12), each of which disks is configured with a plurality of ramp contours (8). An annular cage (2) that carries a plurality of rolling elements (3) is inserted between the first ramp disk (11) and the second ramp disk (12). At least the first ramp disk (11), the second ramp disk (12) and the cage (2) are made by a shaping method without chip removal. Each of the first ramp disk (11) and the second ramp disk (12) is configured with a continuous wall (32). Likewise through this shaping method, the first ramp disk (11) and the second ramp disk (12) have on an outer periphery (UA) an integrally formed safety stop device (14) for respective end positions.

The invention relates to thin-walled rolling bearings, such as needle bearings, which are produced without the removal of material and the outer rings of which form a structural unit and are produced from a cold-rolled strip. According to the invention, the outer rings are produced from a cold-formable, fully hardenable steel, a ratio of from 1:20 to 1:5 being set between their wall thickness and the diameter of the bearing needles, and the fully hardened wall having a core hardness of ≧600 HV and a surface hardness of ≧680 HV. The invention makes it possible for bearings to withstand higher static bearings than bearings made from conventional steels while taking up the same installation space.

The invention relates to a bearing arrangement (1) comprising an at least partially planar bearing support (2) that has a supporting bore (5), and at least one bearing (6) which is connected to said bearing support (2). An external ring (7) of the bearing (6) is provided with a recess (14) for accommodating the bearing support (2). According to the invention, the axially internal end of the recess (14) has an undercut (15), the diameter (D1) of which in relation to a bearing axis (11) is smaller than a diameter (D2) formed by an axially extending section of the recess (14). A slotted ring-type holding element (16) which positively covers the bearing support (2) in a radial direction in at least one circumferential point is inserted into the undercut (15).

The invention proposes a mechanical roller tappet (1a, 1b) comprising a tappet housing (2a, 2b) shaped out of sheet metal, a drive roller (3) actuable by a cam (9) and an axle (5a, 5b) on which the drive roller (3) is mounted, end portions (24) of the axle (5a, 5b) being supported in axle eyes (23) of the tappet housing (2a, 2b), said tappet housing (2a, 2b) comprising a tappet skirt (10a, 10b) and a tappet bottom (16) possessing a contact surface (21) for an adjacent engine component on a power take-off side. At an end of the tappet skirt facing the cam, the tappet bottom is connected to the tappet skirt and is shaped into the interior of the tappet skirt while forming a pocket for receiving the drive roller, the axle eyes being arranged in first sections (18) of the tappet bottom while being spaced from an inner peripheral surface (19) of the tappet skirt and extending substantially parallel to the longitudinal direction of the tappet skirt, the contact surface being arranged on a second section (20) of the tappet bottom connecting the first sections to each other.
摘要:
A mechanical tappet (101, 201, 301, 401, 501, 601, 701, 801, 901, 1001) is provided, in particular for actuating the lifting of a pump piston (39) of a fuel pump of an internal combustion engine, with a sleeve-shaped tappet housing (102, 202, 302, 402, 502, 602, 702, 902, 1002) constructed as a shaped sheet-metal part and with a driving roller (6) supported so that it can rotate. Here, a bolt (4) supports the driving roller so that it is centered, and end sections (7) of the bolt projecting from the driving roller are supported in bolt eyes (8) of the tappet housing.
