20130175133WRAP SPRING CLUTCH ACTUATOR AND METHODS FOR SAME - A wrap spring clutch system includes one or more wrap spring clutch assemblies each having a latching actuator assembly. The latching actuator assembly includes an armature plunger movably coupled with a solenoid coil, and in a powered solenoid coil state the solenoid coil moves the armature plunger between deployed and retracted configurations. A latching magnet latches the armature plunger in one of the deployed or retracted configuration in an unpowered solenoid coil state. A latching spring latches the armature plunger in the other of the deployed or retracted configuration in an unpowered solenoid coil state. The wrap spring clutches include a rotatable input hub and a rotatable output hub configured for rotation by the input hub. A helical spring is engaged with the output hub and selectively engaged in slipping and locking engagement with the input hub according to the deployed or retracted configuration of the armature plunger.07-11-2013
20080257676Flexible drivetrain having axial and radial motion limiter - A drivetrain for use with a power unit is disclosed. The drivetrain may have a crankshaft, a flywheel having spline teeth, and a flexible plate connecting the crankshaft to the flywheel. The drivetrain may also have a driven member having spline teeth configured to mate with the spline teeth of the flywheel, and a limiter associated with at least one of the flywheel and the driven member. The limiter may be configured to limit a maximum axial movement and a maximum radial movement between the flywheel and the driven member.10-23-2008
20100140035Bicycle clutch - A bicycle clutch comprises a transmission shaft, at least two gears, at least two slide blocks, at least two clutch blocks, at least two guiding blocks, a switch shaft and a stationary shaft. The gears and the slide blocks are coaxially disposed on the transmission shaft. The sliding blocks, switch shaft and stationary shaft are coaxially assembled. The clutch blocks are disposed on the transmission shaft, the gears and the slide blocks. The guiding blocks are disposed on the switch shaft and the slide blocks. Through angle deflection, the clutch can selectively make one of the gears engage with the driven assembly to change the rotation speed.06-10-2010
