Abstract: A clutch hub is selectively held against rotation by a brake and selectively coupled to an input shaft by a clutch. The clutch pack for the brake is splined to the outside of the clutch hub while the clutch pack for the clutch is splined to the inside. To reduce axial length, the clutch packs are packaged radially outside of a gear set, increasing the diameter of the clutch hub. When the clutch hub is subjected to high rotational speeds, high centrifugal stresses result. These stresses are reduced by openings in the spline teeth and in the recesses between the spline teeth. Fluid flow to the outer clutch pack is controlled by openings in a clutch housing.

Abstract: Certain embodiments of the present disclosure describe a clip for biasing and maintaining rollers within an opening of the roller bearing assembly. The clip includes a connecting segment, a resilient portion, and an anchor portion. The clip may be attached to a roll cage with openings for rollers. The resilient portion of the clip extends into an opening and contacts the roller when a roller is received in the opening. The anchor portion is positioned in an adjacent opening and abuts the roll cage.

Abstract: A clutch device for arrangement in a drive train of a motor vehicle between a drive unit and a gearbox, which comprises a clutch for optional torque transmission between the drive unit and the gearbox, a clutch input side to which a torque from the drive unit can be transmitted, and an electric machine allocated to the clutch input side, wherein an overrun to transmit the torque from the drive unit in only one rotational direction is arranged upstream of the clutch input side in relation to the torque transmission path.

Abstract: A vehicle includes a transmission, which is characterized by the absence of a friction clutch that is operable to limit torque transfer between the drive wheels and a shaft of the transmission, to prevent torque communication between the drive wheel and the shaft. The transmission includes a selectable one way clutch, which interconnects a housing of the transmission and the shaft. The selectable one way clutch is selectively operable to prevent rotation of the shaft in at least one rotational direction. The selectable one way clutch includes a torque limiting system, such as a ball-detent torque limiting mechanism, which is operable to prevent torque transfer greater than a pre-defined value, between the housing and the shaft.

Abstract: An elevator may include an elevator car, a set of hoisting ropes, a hoisting machine, a traction sheave, and a brake. The elevator car may be suspended on the hoisting ropes. The hoisting machine may drive the traction sheave to move the elevator car using the hoisting ropes. The brake may include a brake wheel and brake shoes. The brake may exert an effect on rotation of the traction sheave. During braking, the effect of the brake on the rotation of the traction sheave may depend on a direction of rotation of the traction sheave. The effect of the brake on the rotation of the traction sheave may be greater when the direction of rotation of the traction sheave during braking corresponds to the elevator car moving downward than when the direction of rotation of the traction sheave during braking corresponds to the elevator car moving upward.

Abstract: A clamping roller freewheel, which has an inner ring, an outer ring and clamping rollers arranged between the inner ring and outer ring. The clamping rollers interact, in each case, with one clamping ramp formed on the outer circumference of the inner ring. The clamping rollers are surrounded by an elastically expandable protective ring which is concentric with respect to the freewheel axis.

In this way, the outer ring is prevented from grinding against the clamping rollers, and the clamping rollers are prevented from being driven in rotation, with the resulting wear to the clamping ramps, in idle running operation.
