Clutch and gear synchronizer module

摘要

A clutch and gear synchronizer module includes an actuator disposed radially with respect to the transmission shaft and carried by an actuator carrier connected to the transmission shaft for rotation with the transmission shaft. The actuator includes an offset pin coupled to a shift sleeve that is able to move axially with respect to the transmission shaft thereby causing axial and rotational movement of the offset pin and rotation of the actuator about an actuator axis. The actuator includes a lobe and a pawl. Sequentially, the lobe engages a friction ring thereby causing the friction ring to engage the gear and causing the gear to rotate in synchronization with the transmission shaft. As the shift sleeve moves further towards the gear, the pawl then engages clutch teeth disposed on an annular surface of the gear.

1. A clutch and gear synchronizer module for a transmission that includes a transmission shaft that passes coaxially through a first gear assembly, the first gear assembly including a frictional surface and a recess, the transmission shaft being rotatable about a transmission axis, the clutch and gear synchronizer module comprising:
an actuator carrier mounted on the transmission shaft for rotation with the transmission shaft about the transmission axis, the actuator carrier disposed radially within and coupled to a shift sleeve for imparting rotation to the shift sleeve while enabling the shift sleeve to move axially with respect to the actuator carrier, the actuator carrier including an inner hub connected to an outer ring with a window disposed between the inner hub and the outer ring, a first friction element disposed between the first gear assembly and the actuator carrier and coupled to the actuator carrier for rotation with the actuator carrier while enabling the first friction element to move axially with respect to the actuator carrier, and an actuator that extends radially between the inner hub and the outer ring and across the window of the actuator carrier, the actuator being rotatable about an actuator axis that extends radially between the inner hub and the outer ring, the actuator including a lobe and a pawl disposed in radial alignment with the window, the lobe also in radial alignment with the first friction element, the pawl also in radial alignment the frictional surface of the first gear assembly, the actuator further including an outwardly directed offset pin that is parallel to but not coaxial with the actuator axis, the offset pin coupled to the shift sleeve.
