The present invention relates to an ejector clutch (1) for a belt tensioner, comprising a first shaft (10), a second shaft (20), and a coupling part (30), wherein the coupling part (30) is arranged between the first shaft (10) and the second shaft (20) in a longitudinal axis (X) defining an axial direction, wherein the coupling part (30) has at least one clutch finger (40), which engages in a first recess (15) of the first shaft (10) for transmitting a torque (M) and, when a torque (M2) to be transmitted is exceeded, said clutch finger is displaced, against a spring force in the axial direction, from the first recess (15) of the first shaft (10) into a second recess (25) of the second shaft (20). The invention further relates to a belt tensioner with an ejector clutch (1).

The present invention provides a rotary shaft assembly applied to a novel clutch system that ensures a 100% torque transmission rate between an engine and a transmission in a vehicle system and can be commonly applied to conventional manual transmission vehicles and automatic vehicles. The rotary shaft assembly converts linear motion of one member to rotary motion of another member, using a combination of a protrusion and an inclined guide slot.

A brake device for a motor vehicle seat is composed of a brake assembly, a tooth assembly, and a lever assembly. The brake assembly includes a housing, a pinion shaft, a braking component, and a drive wheel that are structured to be self-held in an assembled state by mechanical interaction thereamong. The tooth assembly includes a holder plate and a tooth plate that are structured to be self-held in an assembled state by mechanical interaction therebetween. The lever assembly includes an input lever, a cover, a coil spring, and a lever bracket that are structured to be self-held in an assembled state by mechanical interaction thereamong. The brake assembly, the tooth assembly, and the lever assembly are arranged and assembled together in an axial direction.

The present invention provides a new clutch system that ensures a 100% torque transmission rate between an engine and a transmission in a vehicle system, that can be commonly applied to conventional manual transmission vehicles and automatic vehicles, and that operates in conjunction with an accelerator pedal and a brake pedal.

The clutch assembly of the clutch system according to the present invention can precisely transmit or cut off power from an engine to a transmission by pressing and releasing of an accelerator pedal and a brake pedal.

A transmission system for a hybrid power plant, such as a hybrid propulsion system of a marine vessel, is described. The transmission is configured to selectively couple a primary mover and/or a secondary mover to an output of the transmission for providing a power output, and optionally selectively couple the primary mover to the secondary mover, decoupling the output, for electrical energy generation in a compact and light-weight design.

A differential includes a driven body, an output element, and a clutch assembly radially interposed between the driven body and the output element. The clutch assembly includes a first wedge clutch configured to rotationally lock the output element to the driven body in a first direction and to overrun in a second direction, and a second wedge clutch configured to rotationally lock the output element to the driven body in the second direction and to overrun in the first direction.

According to one aspect, a releasable roller clutch includes a shaft and a clutch housing positioned around the shaft. The shaft and clutch housing together defining a space there between with rollers positioned in said space. The rollers permit rotation of the shaft relative to the clutch housing when in an unlocked position in which the rollers are not wedged and prevent rotation of the shaft relative to the clutch housing when in a locked position in which the rollers are wedged. A cage extends into the space defined between the shaft and clutch housing. The cage is moveable relative to the clutch housing between an unlocking position and a locking position. The cage has a contact edge positionable to prevent the rollers from moving from the unlocked position to the locked position when the cage is in an unlocking position. The releasable roller clutch permits rotation of the shaft relative to the clutch housing in both directions when the cage is in the unlocking position.
