Abstract
A drive belt tensioner for mounting to a motor-generator unit comprises a tensioner pulley support having a centrally located pivot defining a pivot axis and first and second reaction arms extending outwardly from the centrally located pivot to define an angle therebetween. Tensioner pulleys are rotatably mounted to the second ends of each of the first and second reaction arms. The reaction arms are configured to flexibly bias the tensioner pulleys when engaged by a drive belt force to maintain a desired drive belt tension.
