Abstract: A belt pulley decoupler for transmitting drive torque from the belt of an auxiliary unit belt drive to the shaft of one of the auxiliary units is provided, including: a belt pulley, a hub to be mounted on the shaft, a first sleeve, which is rotationally fixed in the pulley, a second sleeve, which is rotatable in the pulley, and a series circuit of a decoupler spring and a disposed in the drive torque flow between the belt pulley and the hub. The wrap-around band ends, which couple the two sleeves to one another non-rotatably while transmitting the drive torque, extend the wrap-around band radially. One of the two sleeves has a circumferentially extending slot and the wrap-around band end coupled to this sleeve is configured as a leg, which interlockingly engages in the slot non-rotatably in a direction of rotation of the drive torque.

Abstract: A plate-link chain, in particular for a continuously variable transmission of a motor vehicle, having plate links which are connected to each other in an articulated manner by pairs of rocker pressure members, each including two rocker pressure members. The plate links and the rocker pressure members are designed in such a way as to bear against each other at respective flat contact surfaces so that the load on plate-link bands of the plate links is nearly torque-free during operation of the plate-link chain.

Abstract: A freewheel device for a motor vehicle includes an inner ring and an outer ring as well as at least one clutch disk. The at least one clutch disk is arranged radially between the inner ring and the outer ring and is formed by a plurality of segments, which are each connected to one another tangentially by an elastic element. The inner ring has, on an outer circumferential surface, a multiplicity of ramps, which interact with ramps, formed in a manner corresponding thereto, on an inner circumferential surface of the at least one clutch disk in order to allow a freewheeling function between the inner ring and the outer ring during a first rotation of the inner ring and to allow a locking function between the inner ring and the outer ring during a second rotation of the inner ring, which is opposed to the first rotation.

Abstract: An improved friction part for a frictionally operating device includes friction lining pieces, which are spaced apart from each other by grooves in order to create a friction surface in the form of a circular-ring-shaped disk, especially in respect of suitability for production and/or functionality. In an example embodiment, the friction part has friction lining pieces, which are spaced apart from each other by grooves in order to create a friction surface in the form of a circular-ring-shaped disk, if some or all of the friction lining pieces are in the shape of triangles. The triangular friction lining pieces may be arranged in a plurality of circumferential rows. The grooves between the friction lining pieces may extend as far as a carrier element. Virtually waste-free usage of the linings is thereby possible. A carrier plate can be used as a carrier element, for example.

Abstract: A drive train for a motor vehicle, in particular a hybrid vehicle, having a drive shaft that can be connected to an internal combustion engine, and a transmission oil pump that can be coupled to the drive shaft by means of a switchable freewheel. An electrical machine for driving the transmission oil pump is also provided and is arranged in the power flow direction between the drive shaft and the transmission oil pump, and is in parallel to the freewheel in the power flow direction. A second freewheel is unnecessary and thereby reduces the construction space needed for the power train.

Abstract: A torque sensor for a belt-driven conical-pulley transmission. A first ramp surface is rigidly connected to a shaft of a conical disk pair, and a second ramp surface is rigidly connected to a sensing piston surrounding the shaft and axially and rotatably movable relative to the shaft. Balls are positioned between and in contact with the ramp surfaces and with a guide surface rigidly connected with an axially movable disk. The guide surface is so configured that the contact points of a particular ball with the ramp surfaces, the contact point of that ball with the guide surface, and the center point of that ball lie in a radially oriented plane.

Abstract: A sensing device integrated into a conical disk pair includes a sensing piston that is axially movable relative to the input shaft over a radially stepped guide surface that is formed on a shaft on which the sensing device is carried, and a corresponding opposing stepped surface formed on the sensing piston. The steps define a damping chamber between the guide surface and the opposing surface, whose volume changes when the sensing piston moves axially relative to the shaft.

Abstract: An adjusting device including a CVT planetary roller transmission having two axially-spaced sun wheels that are rotatable about a common axis of rotation and at different speeds of rotation. Planet wheels contact and ride against peripheral surfaces of each of the sun wheels, and an axially displaceable ring wheel lies radially outwardly of the sun wheels and engages a peripheral groove formed in the sun wheels. When the ring wheel is axially displaced relative to the sun wheels the axes of rotation of the planet wheels tilt relative to the sun wheel axis resulting in a difference in the rotational speed of the sun wheels changes. The device can be employed as an adjusting device for adjusting the rotational speed of connected units, and also as a drive line component having a variable transmission ratio and situated in a power train of a motor vehicle.
