20130175133 | WRAP 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 |
20080257676 | Flexible 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 |
20100140035 | Bicycle 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 |
20140238807 | CLUTCH SWITCHING DEVICE FOR ELECTRIC ROLLING DOOR - A clutch switching device for electric rolling doors contains: a housing, a rotating plate, and a shifting bar. The rotating plate is provided in the housing for connecting with the clutch pulling cord. The shifting bar is coupled with the rotating plate and is pulled to drive the rotating plate to move toward a manual mode position or an automatic mode position. The rotating plate has a wrenching portion for matching with a wrench tool so as to wrench the rotating plate. The housing includes a movable fixing element, the rotating plate has a first positioning aperture and a second positioning aperture, such that when the rotating plate is located at a manual mode position, the first positioning aperture aligns and retains with the movable fixing element; when the rotating plate is located at the automatic mode position, the second positioning aperture aligns and retains with the movable fixing element. | 08-28-2014 |

20150053522 | STARTER AND RETARDER ELEMENT, AND METHOD FOR OPERATING A STARTER AND RETARDER ELEMENT - A start-up and retarder element having a hydrodynamic transfer element ( | 02-26-2015 |
20160016570 | Transmission Hydraulic Retarder Control System and Method of Operating - A method of operating a hydraulic retarder includes directing fluid from a retarder pump to the retarder when the retarder is turned on, directing fluid from a main pump by way of a torque converter to the retarder when the retarder is on, but not filled. When the retarder is off or is on and filled, the method includes directing fluid from the main pump by way of the torque converter to at least one of a lube operation, the tank or a cooler. | 01-21-2016 |
