Patent number: 8157077Abstract: A clutch device for an electric winch includes a ring gear that is settled in a gear box and is in communication with a gear mechanism of the electric winch. A plurality of braking recesses are provided on the outer periphery surface of the ring gear. A detachable clutch sleeve is fixed in a braking port defined in the gear box and includes a T-shaped clutch lever. A clutch handle is provided on the sleeve. The inner surface of the clutch handle and the top surface of the clutch sleeve are cam faces formed by double tapered faces. A rotating-positioning mechanism, which can be rotated 180 degrees, is provided between the clutch handle and the clutch sleeve. The clutch lever is movable between an engaged position, where the clutch lever engages the braking recesses, and a disengaged position, when the clutch handle is rotated in clockwise and anticlockwise directions.Type: GrantFiled: August 13, 2007Date of Patent: April 17, 2012Inventors: Yuzhi Xie, Kuo-hsiang Tsao

Patent number: 7857289Abstract: The present invention discloses a tapered braking device for electric winches which disposes a section of gear shaft, a section of core shaft, a wedge shape support, braking plates, an elastic element, a wedge shape piece A, a wedge shape piece B, a braking clutch base and so on in a gear box of an electric winch. When a motor works, the section of core shaft of the motor can drive the braking clutch base and the wedge shape pieces A, B to rotate, until a gap is formed between the friction faces of the wedge shape support and the wedge shape piece B and the braking plates so that the braking action stops. When the motor suddenly stops, a heavy load lifted by a tight wire rope reel provides a reverse pulling force so that the wedge shape piece B produces a reverse thrust force to push the friction faces of the braking plates, so the braking effect is achieved quickly.Type: GrantFiled: August 13, 2007Date of Patent: December 28, 2010Inventors: Yuzhi Xie, Kuo-Hsiang Tsao

Patent number: 7823864Abstract: The present invention discloses a plane braking device for electric winches and electric winch which disposes a section of hollow gear shaft, a section of core shaft, a fixing ring, a wedge shape support, a stopping piece, a braking plate, an elastic element, a wedge shape piece B, a wedge shape piece A, a braking clutch base and so on in a gear box of an electric winch. When a motor works, the section of core shaft of the motor drives the braking clutch base and the wedge shape pieces A, B to rotate, until a gap is formed between the adjacent braking plate and stopping piece between the braking clutch base and the wedge shape piece B, so that the braking effect disappears. When the motor stops suddenly, a heavy load lifted by a tight wire drum provides a reverse pulling force so that the wedge shape piece B produces a reverse thrust force to push the friction planes of the braking plate and the stopping piece, so the plane braking effect is achieved quickly.Type: GrantFiled: August 13, 2007Date of Patent: November 2, 2010Inventors: Yuzhi Xie, Kuo-hsiang Tsao
