A torque limiter assembly includes a first rotational form mounted to a driving component of rotational dive system the first rotational form adapted to receive a second rotational form mounted to a driven component, the forms rotational over a shared hub, the second form adapted to engage to and be disengaged from the first form by a plurality or disconnect assemblies spaced equally around and mounted through a sidewall of the first rotational form, each disconnect assembly a spring assisted piston and a tensioner adapted to engage a detent in the second rotational form, the disconnect assemblies operable in unison to disengage from the second rotational form from the first rotational form upon detection of breach of a torque load threshold value set for each of the disconnect assemblies.

The invention relates to an electrically driven clutch actuators (1) for actuating the clutch of a transmission of a vehicle. An actuator comprises a spindle nut (11) on a spindle (9) and a pressure piece (13) displaceable relative to the spindle nut (11) and coupled to the spindle nut by a biasing spring (15). By rotation of the threaded spindle under a driving force of an electric motor (5), the spindle nut (11) compresses the biasing spring (15) and displaces the pressure piece (13) to disengage the clutch. A latching mechanism (16) is configured to limit displacement of the spindle nut away from the pressure piece under the force of the expanding biasing spring when the driving force is reduced below a predetermined level. Further, a control unit is described that reduces the driving force in response to a trigger condition to reduce power consumption in the clutch disengaged state.

A torque limiter assembly is disclosed comprising a housing having at least one first engagement member, an input shaft that is rotatable relative to the housing and having at least one second engagement member; and an electromagnet. The electromagnet 10 is arranged and configured such that when activated it generates a magnetic field that moves the at least one first engagement member relative to the at least one second engagement member, such that the first and second engagement members engage each other and stop or inhibit rotation of the input shaft relative to the housing.

A clutch for preventing backdrive, includes a housing: a cover portion positioned on one end portion of the housing; an external shaft, at least one portion of which is positioned inside the housing, the other end portion thereof passing through the housing; a rocker positioned between the housing and the cover portion and fastened to the external shaft; an input shaft, one end portion thereof being inserted into an opening portion in the locker, and the other end portion thereof passing through the cover portion; and a gear portion positioned on the housing or the cover portion so that a serrated portion positioned on the locker is selectively brought into contact with the gear portion, wherein rotation of the rocker is restricted so that the external shaft is rotated along a rotation direction of the input shaft.

A shaft interlock system may have an a interlocking piston that translates a movable locking apparatus configured to interface with a turbine shaft having a fixed locking apparatus. The movable locking apparatus may engage and disengage the fixed locking apparatus. When the movable locking apparatus is engaged with the fixed locking apparatus, the turbine shaft is only able to turn in one direction. When the movable locking apparatus is disengaged from the fixed locking apparatus, the turbine shaft is able to turn in both directions. In this way, a turbine shaft can be prevented from reverse rotation.

A portal gear and a method to implement a portal gear for a model vehicle are provided. The portal gear may include a drive shaft attached to an input gear and an axle attached to an output gear. The portal gear may further include a housing to vertically contain the input gear and the output gear. Wherein the drive shaft transfers a rotational torque from an upper location to a lower location via a gear reduction resulting from the input gear rotating the output gear.

A manual/automatic dual-purpose clutching structure includes a driving gear assembly, a reversing clutching assembly and a driven gear assembly. The driving gear assembly includes a first gear, a second gear and a driving module, the first gear being coaxially and fixedly connected to the second gear. The reversing clutching assembly includes a reversing gear and a reset spring, the reversing gear is located on one side of and meshes with the second gear. The driven gear assembly includes an output gear which is located on the other side of and does not make contact with the second gear. The reversing gear rotates around a central axis of the second gear under a driving of the driving module to mesh with the output gear. After power of the driving module disappears, the reversing gear is prompted to be disengaged from the output gear under an action of the reset spring.

A rotary shifter assembly for changing gears in a vehicle transmission includes a shaft (16) that is rotatably supported in a housing (12) and movable between radial positions for indicating a gear change. A shift knob (10) is coupled to a first end of the shaft for actuation by a user. A plurality of flexible locking fingers (40) extend from the second end, and an overload wheel (18) is disposed about the fingers. The fingers engage the wheel to couple it with the shaft for concurrent rotation. A locking mechanism (64) engages the wheel to selectively prevent and allow concurrent rotation of the wheel and shaft during normal operation. The fingers move relative to the wheel to permit temporary rotation of the shaft relative to the wheel when a force applied to the shaft is beyond a maximum torque threshold, and automatically return to concurrent rotation with the wheel once the force is below the threshold.

A clutch includes inner and outer races, each with pluralities of teeth. A pawl is supported on the inner race and a shift ring disposed outward of the pawl defines pawl engagement surfaces on an inner perimeter. Pins engage cam surfaces formed in the ring and outer race. When the inner race rotates faster than the outer race, the pawl engages the ring causing relative movement between the ring and outer race that moves the pins radially inward along the cam surfaces to locate the pins between corresponding teeth on the races and rotatably couple the races. When the outer race rotates faster than the inner race, the ring moves relative to the outer race and the pins move radially outward along the cam surfaces away from the corresponding teeth to uncouple the races, disengage the ring from the pawl and allow the outer race to overrun the inner race.
