ABSTRACT:
A transaxle having five forward speeds and reverse includes a shift shaft on which are journalled for free rotation four forward speed change gears and an input bevel gears which is integrally conjoined with a first speed change gear. A reverse gear is also journalled for free rotation on the shift shaft and a neutral spacer is disposed between reverse gear and the four forward gears. A counter shaft carries five companion spur gears in constant running mesh with the forward speed change gears. One of the companion gears is also in constant running mesh with a reverse intermediate gear which is in constant running mesh with the reverse gear. The reverse intermediate gear is supported by a half-bearing in the transaxle housing. A pair of axially slidable and radially outward biased shift keys on the shift shaft selectively couple the forward speed change gears, the input bevel gear, and the reverse gear to the shift shaft. High gear is provided by coupling the bevel gear directly to the shift shaft and bypassing the counter shaft. A differential driven by a spur gear on the shift shaft drives the output drive shafts of the transaxle. A disc brake is provided on the shift shaft.
