摘要： A mechanical backstop is provided which comprises a housing, an input impact gear, a frictional plate, a floating impact gear, and an output impact gear. The floating impact gear is movably mounted between the input impact gear and the output impact gear to achieve transmission. The frictional plate is fixed relative to the housing and disposed at a side of the floating impact gear close to the input impact gear. When the input impact gear transmits a torque to the floating impact gear, the floating impact gear floats toward the output impact gear to separate from the frictional plate and transmit the torque to the output impact gear. When the floating impact gear transmits a torque reversely, the floating impact gear floats toward the input impact gear to abut against the frictional plate and achieve reverse locking.

摘要： A slipper clutch transmission brake includes a clutch housing, a pin, a slipper clutch outer race rotationally fixed in the clutch housing, a slipper clutch inner race, a plurality of first cylindrical rollers, and a clutch inner ring. The clutch housing has a radial aperture and the pin is disposed in the radial aperture. The outer race has inner bidirectional ramps arranged on an inner circumference. The inner race has outer bidirectional ramps arranged on an outer circumference, a notch for receiving the pin, and a split extending axially through its width. The plurality of first cylindrical rollers are arranged in respective gaps formed between the inner and outer bidirectional ramps. The inner ring is arranged to rotate relative to the slipper clutch inner race when the pin is engaged with the notch, and frictionally engage with the slipper clutch inner race when the pin is disengaged from the notch.

摘要： A brake-side clutch part includes an outer ring whose rotation is restricted and an output shaft from which rotation is output. The outer ring is provided with a slide gear that meshes with the output shaft when rotational torque is cut off and releases a meshing state with the output shaft when rotational torque is transmitted. The output shaft is provided with an inner gear that meshes with the slide gear so as to be slightly rotatable. An alignment part that aligns a phase of the inner gear with that of the slide gear when rotational torque is cut off, and a centering part that returns the inner gear to a neutral position with respect to the output shaft when rotational torque is transmitted are provided between the inner gear and the output shaft.

摘要： The reverse input cutoff clutch includes: a pressed member having a pressed surface around the inner peripheral surface; an input member coaxially arranged with the pressed surface and having an input-side engaging portion arranged on the radially inner side of the pressed surface; an output member coaxially arranged with the pressed surface and having an output-side engaging portion arranged further on the radially inner side than the input-side engaging portion; and an engaging element arranged so as to be movable in a first direction as a direction toward or away from the pressed surface on the radially inner side of the pressed surface. The engaging element has a main engaging element body having a pressing surface and a pivot-support shaft, and a link member. The link member has a first end portion pivotally linked to the pivot-support shaft, and a second end portion pivotally linked to the input-side engaging portion.

摘要： A power closure actuator for powering a movable closure includes an output member configured to drive movement of the movable closure, a motor coupled through a gear reduction to drive the output member, and an integrated brake-clutch unit having an input configured to receive drive power from the electric motor. The brake-clutch unit provides independent braking and clutching between the electric motor and the output member via an electric brake actuator and an electric clutch actuator, respectively. Brake and clutch portions of the brake-clutch unit act on a rotor, and brake force can be maintained on the rotor without powering the brake actuator. A clutch disc is biased disengaged from the rotor. The integrated brake-clutch unit provides a drive state between the electric motor and the output member when the brake portion is released concurrently with the clutch portion establishing a power coupling between the clutch disc and the rotor.
