Abstract
An automobile auxiliary power transmission having a synchronizer mechanism comprised of a synchronizer hub, a pair of synchronizer rings cooperating respectively with a low speed and high speed gears, and an axially movable synchronizer sleeve. The synchronizer sleeve has spline teeth for engagement with the synchronizer hub and with the synchronizer rings and the gears. The spline tooth on the sleeve has an axial length which is sufficient to engage with both of the synchronizer rings when it is disengaged from both of the gears. The arrangement is effective to make the shifting stroke of the sleeve smaller than that in conventional structures.
