Abstract: A gear shifting system is described that includes an first shaft that is connected to a motor to be rotated thereby, a synchronizing gear, a first insert unit and a second insert unit protrude at both sides thereof, a first gear and a second gear configured to rotate around the first shaft, a first plate and a second plate, a first engagement aperture and a second engagement aperture, and a second shaft. The second shaft is configured to move the synchronizing gear in an axial direction so that the first insert unit is inserted into the first engagement aperture or the second insert unit is inserted into the second engagement aperture to transfer a torque of the synchronizing gear to the first gear or the second gear.

Abstract: The present invention relates to a power transmission device for a water pump, including a pulley, a magnetic flux generator, a disk assembly, and a hub assembly, wherein the disk assembly has a disk, a friction ring for providing a frictional contact with the hub assembly, and a resilient ring adapted to pressurize the friction ring toward the hub assembly, so that when the attracting magnetic flux of the magnetic flux generator is not applied, the friction ring makes a frictional contact with the hub assembly through the resilient pressurization of the resilient ring, whereas, when it is applied, the disk moves toward the pulley to allow the frictional contact between the friction ring and the hub assembly to be released.

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.
