摘要： A transmission having an input shaft and an output shaft, where an input gear is rotatably fixed for common rotation by the input shaft, an output gear is rotatably fixed for common rotation by the output shaft, and a third shaft is disposed generally parallel to the input and output shafts and has an outer surface that includes a splined portion and a non-splined portion. A reverse gear assembly rotatably fixed for common rotation by the third shaft includes a reverse gear, a synchronizer member, an annular retaining member, and a synchronizer spring. The reverse gear is disposed on the third shaft, and has a hub extending from a first side. The reverse gear assembly is selectively axially moveable along the third shaft to engage the input and output gears.

摘要： A heat storage and release system for a transmission includes a material capable of super cooling within an operating temperature range of the transmission. The material is in thermal communication with the transmission. An energy input device is associated with the material and operable to input energy to the material to initiate an exothermic phase change within the material in order to deliver heat to the transmission.

摘要： A synchronizer assembly includes a synchronizer sleeve that engages a first gearwheel of the transmission. The synchronizer sleeve and the first gearwheel are rotatable about a shaft, and the synchronizer sleeve is axially moveable along the shaft. The synchronizer assembly further includes a synchronizer ring that contacts a second gearwheel of the transmission to selectively engage the synchronizer sleeve. The synchronizer ring includes a synchronizer spring that selectively abuts the second gearwheel to push the synchronizer ring against the synchronizer sleeve, and a plurality of lugs that engage the second gearwheel. The synchronizer spring is retained on the plurality of lugs.

摘要： A transmission is disclosed having an input shaft or member, an output shaft or member, a plurality of meshing gears, a plurality of synchronizers and a reverse idler gear assembly. The reverse idler gear assembly includes an idler gear member, a synchronizer member and a retainer member. The synchronizer member has a pair of tabs that engage grooves on an idler shaft and interface with a synchronizer spring to apply a force from the synchronizer member on the retainer member and create a braking friction to slow down the idler gear assembly and the input shaft prior to meshing with the gear of the output shaft.

摘要： A transmission synchronizer assembly is provided that alleviates noise associated with functional clearances and backlashes. A synchronizer ring is provided that has a periphery with at least one tab extending at least partially radially at the periphery. An annular hub has at least one recess configured to receive the at least one tab to axially align the synchronizer ring with the hub. The recess and the tab define a clearance when the tab is received in the recess. A damping material is provided in the clearance such that the damping material contacts the annular hub when the synchronizer is moved about the axis of rotation relative to the annular hub. Such movement may occur during engagement of an annular sleeve with a gear whose speed is synchronized with the sleeve by the synchronizer ring.
