This disclosure relates to a fluid friction clutch having a housing, a clutch disc which is arranged at one end of a shaft which is mounted within the housing, a working chamber which is configured between the housing and the clutch disc, a storage chamber for clutch fluid, and at least one feed duct which leads from the storage chamber to the working chamber. Moreover, a pressure relief device for discharging clutch fluid from the feed duct into the storage chamber is provided.

A friction clutch for coupling a drive shaft of a motor vehicle engine to a transmission input shaft of a motor vehicle transmission. An input disk carrier is couplable to the drive shaft and an output disk carrier is couplable to the transmission input shaft. A return spring positions the output part in a defined initial position relative to the input part. The return spring allows a higher pressing force between the input part and the output part in the engaged state when the friction lining is in a worn condition than when the friction lining is in the non-worn condition. Through the use of the return spring to also transfer torque, a pressing force that reduces as the friction linings become worn can be compensated for by changing the direction of force of the torque introduced through the return spring for reliable engagement of the friction clutch.

A backing plate configuration and a friction clutch assembly for an automotive transmission are provided. The backing plate configuration includes a main body having a reaction section connected to a perpendicularly disposed strength section. The thickness of the strength section may be less than or equal to the thickness of the reaction section. The friction clutch assembly includes interleaved first and second clutch plates. The main body (of the backing plate) is disposed adjacent to an end second clutch plate. The main body is piloted by and/or splined to the same transmission member as the end second clutch plate. In an engaged position, the end second clutch plate is compressed directly against and into contact with the main body. A method of forming the backing plate configuration is included, which includes stamping of the main body.

A speed adjustable returning apparatus for an electric actuator utilizes a cooperative configuration between the one-way driving device and the clutch device during the use of the apparatus in order to prevent damages caused by the operating unit driven by the opening/closing assembly. In addition, the clutch device is able to allow the operating device to selectively drive the opening/closing assembly in order to prevent impacts on the opening/closing assembly due to accidental movements of the operating device. Consequently, the present invention is able to achieve the effect of preventing damages of relevant equipment and providing a safer uses for applications.

A first drive cam groove extends from a drive cam specific position to one side in a circumferential direction. A second drive cam groove extends from the drive cam specific position to the other side in the circumferential direction, and an inclination angle of a groove bottom with respect to one end surface of the drive cam main body is larger than that of the first drive cam groove. A first driven cam groove extends from a driven cam specific position to one side in a circumferential direction. A second driven cam groove extends from the driven cam specific position to the other side in the circumferential direction, and an inclination angle of a groove bottom with respect to one end surface of the driven cam main body is larger than that of the first driven cam groove.

A differential includes a disconnect feature. When in a disengaged state, the drive gear is decoupled from the differential carrier. As a result, the portions of the powertrain that would provide propulsion through the differential may be stationary and parasitic drag is decreased. The differential is transitioned into an engaged state by providing electrical current in a solenoid coil fixed to the housing. A solenoid piston acts through a thrust bearing to slide a sleeve, thereby coupling the carrier to the drive gear.

A drive device for a washing machine includes a motor, a washing shaft, a dewatering shaft sleeve sleeved on the washing shaft, the washing shaft is coaxially installed in a rotor of the motor, and further includes a planetary gear speed reduction mechanism built in the rotor and the planetary gear speed reduction mechanism includes: a sun-gear sleeve sleeved on the washing shaft and fixedly connected to the rotor; a planetary gear assembly, including a planetary gear meshing with the sun-gear sleeve, and the planetary gear assembly is fixedly connected to the washing shaft via a planetary carrier; the number of the planetary gear is plural, and the multiple planetary gears are evenly distributed about the sun-gear sleeve; and an internally toothed ring gear meshing with the planetary gears and fixedly connected to the dewatering shaft sleeve.
