  • Publication number: 20100307884
    Abstract: An electromagnetic clutch includes an external drive source, a driven apparatus having a rotary shaft, a power transmission path, first and second rotating parts, a power source, an electromagnetic coil and a power cutoff mechanism. A power transmission path is formed between the external drive source and the driven apparatus, and in which the first and the second rotating parts, the electromagnetic coil and the power cutoff mechanism are disposed. The first rotating part is driven to rotate by power from the external drive source. The second rotating part is mounted on the rotary shaft for rotation therewith. The electromagnetic coil is energized by electric current from the power source to generate electromagnetic attraction force by which the first and the second rotating parts are connected for transmitting power therebetween. The power cutoff mechanism stops excessive power transmission from the external drive source to the driven apparatus when the electromagnetic coil is energized.

  • Publication number: 20100170763
    Abstract: A transmission device includes a first transmission mechanism comprising a first rotatable member and a first transmission member fixed to the first rotatable member for rotating together with the first rotatable member; and a second transmission mechanism comprising a second rotatable member and a second transmission member fixed to the second rotatable member for rotating together with the second rotatable member. The second transmission member received in the first transmission member, and the second transmission member being magnetically connected with the first transmission member. When a load applied to the first transmission mechanism is less than a predetermined value of the first transmission mechanism, the first transmission member rotates together with the second transmission member by a magnetic force generated therebetween, which in turn makes the first transmission mechanism rotates with the second transmission mechanism together.

  • Patent number: 7717437
    Abstract: A vehicle stabilizer bar assembly having a pair of stabilizer bar members that are selectively uncoupled via a clutch. The clutch includes a plurality of engagement pins that can be selectively moved via an actuator to effect the uncoupling of the stabilizer bar members. The actuator is configured to apply a force to the moving element concentrically about the axis along which the moving element translates. A method for operating a vehicle stabilizer bar assembly is also provided.

  • Patent number: 7717248
    Abstract: In a process which is for controlling and/or regulating an automated clutch, in particular in the drive train of a vehicle, and in which an actuating element, whose position determines the clutch torque transmissible by the clutch, is actuated for setting a predefined clutch torque according to a characteristic curve, the actuating element is actuated according to a characteristic curve which in a first range of the clutch torque specifies the clutch torque as a function of the position of the actuating element and in a second range of the clutch torque specifies the clutch torque as a function of the force applied to the clutch by the actuating element.

  • Patent number: 7591355
    Abstract: A disconnect (128) is provided for use between an engine (126) and differential (130). The differential disconnect (128) provides for a lock out of the disconnect (128) so as to prevent self energizing. The differential may also include a bottom-out feature to limit the amount of torque that may be transferred through the disconnect. In addition, the disconnect (128) may include a design to contain axial forces on the input shaft (14).

  • Patent number: 6901778
    Abstract: A clutch apparatus of a washing machine is provided. The clutch apparatus includes a coupling unit comprising a magnetic unit at least in one part, combined around the basket shaft, and combined with a rotor of the driving motor in a state where the coupling unit moves downward, the coupling unit for transmitting the rotary power of the driving motor to the basket shaft and a solenoid actuator comprising a solenoid coil and fixed to the lower portion of the tub, the solenoid actuator for supplying electromagnetic repulsive force between the solenoid actuator and the coupling unit so that the coupling unit is separated from the rotor of the driving motor, to thus push the coupling unit upward. The clutch apparatus is formed to have a repulsive type structure unlike a conventional attractive type clutch apparatus. Accordingly, it is possible to collision noise generated when the coupling unit rises and to reduce the amount of consumption of power for maintaining a state where the coupling member rises.
