Abstract: A transaxle is provided especially for small riding vehicles, such as lawn mowers. The transaxle has multiple forward speeds in a compact housing by virtue of a unique gear train arrangement in which shafts serve multiple functions. A driven bevel gear in the transaxle housing is carried on an intermediate portion of a shaft and is backed up by a structurally-integral rib or flange in the housing. This support minimizes lateral deflection of the shaft on which the bevel gear is mounted, when the transmission is under load.

Abstract: There is disclosed herein a mechanical motion control mechanism which in one form may comprise an input shaft drivingly connected to an output shaft in such a manner that continuous rotation of the input shaft produces varying rotational movement of the output shaft characterized by an initial dwell period, an acceleration period, a constant velocity period, a deceleration period and another dwell period. The input and output shafts may be drivingly connected by means of a gear secured to the input shaft which is in meshing engagement with a second gear supported at one end of a pivot arm, the other end of which is secured to the output shaft. Rotational and revolving movement of this second gear is controlled by the interaction of a plurality of cam followers engaging a cam surface so as to allow rotational, revolving, and various desired combinations of such movements in response to rotational movement of the first gear.
