Abstract:
1. A drive belt tensioner assembly for mounting to a motor-generator unit, the drive belt tensioner assembly comprising: a pulley support having a centrally located pivot defining a pivot axis, the pivot having an axial inner end and an axial outer end disposed along the pivot axis, and the pivot having a radially outward cylindrical surface extending from the axial inner end to the axial outer end such that the centrally located pivot is capable of being journably mounted radially within a drive pulley of the motor-generator unit; first and second spring-like reaction arms extending radially outwardly from, and along an axis that extends through, the centrally located pivot to define an angle therebetween; and tensioner pulleys rotatably mounted to first ends of each of the first and second reaction arms and configured to bias a drive belt on both sides of a motor-generator unit drive pulley to maintain tension on a drive belt during driving and driven modes of the motor-generator unit.
