摘要： A synchronizer of a transmission is provided. The synchronizer includes a lower key that is installed to be slidable with respect to a hub in a radial direction of the hub and an upper key that is installed on an exterior of the lower key, the upper key being slidable in an axial direction of the hub. Additionally, a sleeve is installed at an exterior of the hub to slide the upper key in the axial direction while the sleeve slides in the axial direction, to pressurize the upper key toward a synchro ring. A key spring installed between the lower key and the hub to pressurize the lower key and the upper key toward an inner surface of the sleeve.

摘要： A rotor sleeve provides a direct cooling method in which oil flows into the rotor sleeve via a flow passage formed through an input shaft of a transmission and is distributed to a motor coil of a driving motor to cool the motor coil. The rotor sleeve has a flow passage structure capable of maintaining a balance between the amount of oil to be distributed toward a transmission and the amount of oil to be distributed toward an engine.

摘要： A method for controlling revolutions per minute (RPM) flare, in which an RPM of a transmission increases due to clutch slip, for a hybrid vehicle can include: determining whether gear-shifting is performed in a transmission of the hybrid vehicle; detecting whether RPM flare of the transmission occurs when it is determined that the gear-shifting is performed; and controlling a torque of a motor of the hybrid vehicle so as to reduce the RPM flare of the transmission by reducing the torque of the motor when the RPM flare of the transmission is detected.
