A clutch, having an outer race, an inner race, a wedge plate radially arranged between the outer race and the inner race and including an outer circumferential surface, an inner circumferential surface, and a radially continuous space connecting the outer circumferential surface and the inner circumferential surface, and a locking assembly including a displaceable locking component. For a free-wheel mode, the inner and outer races are rotatable with respect to each other. For a locking mode, the locking component is displaceable within the radially disposed space of the wedge plate to engage the wedge plate to radially expand the wedge plate and non-rotatably connect the inner race, the wedge plate, and the outer race.

A water pump for a vehicle includes a power transmission member driven and rotated by an external power, a driven shaft driven to be rotatable independently from the power transmission member, an impeller, an arm member which includes a pressing portion pressing the power transmission member and which is contactable to the power transmission member for transmitting a rotation of the power transmission member to the driven shaft, a control member controlling the arm member so that the arm member and the power transmission member come in contact with each other or come out of contact from each other and so that a contact state between the arm member and the power transmission member is variable, and a biasing member biasing the arm member toward the power transmission member.

A power transmission assembly includes an input member adapted to receive drive torque from a source of torque, an output member adapted to provide drive torque to an output device and a bi-directional roller clutch including a first ring fixed for rotation with one of the input and output members. A second ring is spaced apart from the other of the input and output members. Rollers are positioned in aligned cam tracks formed in facing surfaces of the first and second rings. Neither the first ring nor the second ring support the input member or the output member on the other. The second ring may circumferentially index relative to the first ring for causing the rollers to ride up the cam tracks and force the second ring to frictionally engage the other of the input and output members, thereby establishing a drive connection between the input and output members.

A device for monitoring an area of coverage on a work tool may comprise a lighting unit, a camera, and an evaluation unit. The lighting unit may be adapted to emit light rays for illuminating the area of coverage. The camera may be adapted to detect two-dimensional images of the area of coverage, and the camera may comprise receiving elements arranged linearly. The evaluation unit may be coupled to the camera to evaluate the output signals of the receiving elements to determine a distance value for each receiving element based on the light rays emitted by the lighting device and reflected back from the area of coverage. The evaluation unit may have at least one switching output coupled to the work tool to activate the work tool such that the work tool is operational only if no object is located in the area of coverage.

The invention relates to a shifting element arrangement comprising a cylinder (12) of a first clutch (10), the cylinder being configured as a disk carrier, and a cylinder (23) of a second shifting element (20), the cylinder being configured as a disk carrier or band brake cylinder, wherein the cylinder (12) of the first shifting element (10) comprises a hub driveably mounted on a shaft (40) or on a housing, and wherein the cylinder (23) of the second shifting element (20) radially encompasses the cylinder (12) of the first shifting element (10). Instead of mounting the cylinder (23) of the second shifting element (20) to the hub (15) of the cylinder (12) of the first shifting element (10), it is provided that the cylinder (23) of the second shifting element (20) is rotatably mounted on the outside diameter of the cylinder (12) of the first shifting element (10) by way of a radial bearing (30).

A friction pad for use in a friction element used in a friction engagement device such as a brake or clutch, The friction element includes a carrier and a plurality of friction pads circumferentially spaced about the carrier, The pads may have a modular construction whereby pad portions are releasably secured to support portions. The pads may also be releasably secured to the carrier. Various friction pad constructions are contemplated including constructions in which the secondary support portion includes a membrane and the primary support portion includes a cylindrical member extending between the membrane and the friction pads. A continuous friction pad ring may be substituted for the discrete friction pads, The carrier may be provided with locator pins in the pad receiving bores to orient the pads properly. The carrier may have cuts and grooves formed therein to provide a flexible or even beam mounted support for the friction pads. The friction element may also have a multimode configuration and may include smart structures.

It is proposed in the case of an electromotive power steering as a steering aid for motor vehicles and similar, particularly for the speed range during parking (parking power steering), having a reduction gear between the servo-motor and the steering column or the drive leading on to the mechanical wheel displacement, that at least one clutch block be so arranged that it creates a drive connection from the servo-motor drive to the steering gear side of the steering column when, upon a moment being exerted manually at the steering wheel, a pawl connected to the steering wheel side of the steering column produces the requisite clutch pressure by mechanical action on the at least one clutch block, while the gear wheels acted upon by the clutch are formed as ring gears fitted to a carrier flange which is joined firmly to the driven section of the steering column so that it cannot rotate.

A clutch for providing positive engagement between a driving and driven member. A driving member having tapered V-block cams and aligned tapered rollers in registration therewith are suitably journeled about a hub having a slidably engaged wedge ring adapted to be received by the tapered rollers. Irrespective of whether or not the driving member is in a dynamic or static position, axial movement of the wedge ring against the supported rollers establishes positive engagement between the rollers and the V-block cams providing for the transmission of power from the driving member to the driven member and the supporting shaft. To compensate for the shock inherent in the positive engagement of moving loads or where high inertia loads are moved from zero velocity, shock absorbing members are disposed immediate the wedge ring and supporting hub.
