A torque transmission device (1) is provided for a crossbelt-sorter-cart (200) comprising a crossbelt (210). The torque transmission device (1) comprises a rotatable drive end (10) configured to be coupled to a drive (13, 120) for driving the crossbelt (210) of the crossbelt-sorter-cart (200). A rotatable crossbelt end (20) is configured to be coupled to the crossbelt (210) of the crossbelt-sorter-cart (200). An unrotatable support (30) is configured to be fixed to the crossbelt-sorter-cart (200). A coupling (40) connects the drive end (10) to the crossbelt end (20) at the support (30). The coupling (40) allows a transmission of a drive torque originating from the rotating drive end (10) to the crossbelt end (20) and inhibits a belt torque originating from the rotating crossbelt end (20).

An electrical actuator (20) is provided. The actuator (20) comprises an electric drive means (22) and a drive member (26) being rotationally driven upon activation of the electric drive means (22), an output member (24) being rotationally connected to the drive member (26) by means of a first spring (28), and a second spring (32) being connected to the output member (24) and forming a one way clutch between the output member (24) and a fixed tube (34), wherein the electrical actuator (20) further comprises a regulation cup (30) being configured to engage with the second spring (32) to disconnect the output member (24) from the fixed tube (34).

A drive assembly configured to adjust a motor vehicle closure element including a clutch assembly provided with an input connection and an output connection. The clutch assembly includes a main braking element, configured to brake a movement from the output side, and a freewheel assembly configured to engage the main braking element from movement of the output side and disengage the main braking element by means of a movement from the input side. The brake assembly includes an auxiliary braking element configured to produce a predetermined permanent braking action by means of which the auxiliary braking element acts at least against the movement introduced on the output side, and that the predetermined permanent braking action of the auxiliary braking element has to be overcome to enable the freewheel assembly to disengage.

A pulley structure includes: a cylindrical outer rotation body; an inner rotation body; and a torsion coil spring. The torsion coil spring includes: one end region which is in contact with one rotation body; the other end region which is in contact with the other rotation body; and a middle region. The other rotation body includes: a first contact surface; a facing surface; an inclined surface; and a second contact surface. The facing surface includes a constraining surface connected to the inclined surface. The constraining surface is configured to be capable of constraining the other end region of the torsion coil spring before press fitting so as to prevent a displacement of an axis of the torsion coil spring before the press fitting with respect to an axis of the other rotation body.

The current document is directed to a two-way, by-passable, overrunning clutch incorporated within a mechanical prosthetic knee that provides functionality similar to a biological knee or incorporated in another articulated device, such as a robotic or orthotic articulated device or member. The currently disclosed two-way, by-passable, overrunning clutch allows for two-way free rotation when disabled, but, when enabled, prevents rotation in one direction while allowing free rotation in the other direction. In the mechanical prosthetic knee, the two-way, by-passable, overrunning clutch is enabled by application of a mechanical force and disabled by removal of the mechanical force.

An isolating decoupler comprising a shaft, a pulley journalled to the shaft on at least one bearing, a one-way clutch engaged with the shaft, a torsion spring engaged between the one-way clutch and the pulley, the shaft comprises an inner race of the at least one bearing, and the torsion spring having an end welded to the one-way clutch and having another end welded to the pulley.

The present invention relates to a pulley structure (1) equipped with an outer rotating body (2), an inner rotating body (3), and a coil spring (4) provided between the outer rotating body (2) and the inner rotating body (3). The coil spring (4) is configured so as to undergo torsional deformation in a diameter-expanding or a diameter-contracting direction, thereby engaging the outer rotating body (2) and the inner rotating body (3) and transmitting torque, and to undergo torsional deformation in the direction opposite the direction in which torque is transmitted, thereby entering a disengaged state in which the coil spring slides with the outer rotating body (2) or the inner rotating body (3), thus interrupting the transmission of torque. The number of windings of the coil spring (4) is in a range between [M-0.125] and M (both inclusive), where M is a natural number.

In an aspect, a drive arrangement for a vehicle is provided, comprising: an engine having a crankshaft; a crankshaft pulley; a one-way clutch between the crankshaft pulley and the crankshaft; a belt by the crankshaft pulley; and an electric motor having a pulley engaged with the belt. When the electric motor drives the belt in a first direction, the one-way clutch permits the belt to overrun the crankshaft pulley. The crankshaft defines an axis. The electric motor pulley is on a first axial side of the engine. A transmission is on a second axial side and is operatively connected to drive a vehicle wheel. The transmission has an input shaft. A first rotary drive member is on the input shaft; and a motor-transmission drive shaft is drivable by the motor and has a second rotary drive member thereon, which is operatively connected with the first transmission rotary drive member.
