The belt (34) is operable to transfer mechanical power between the first sprocket (30) and the two secondary sprockets (32). The belt (34) defines a first side having one of a first plurality of notches (40) and a first plurality of teeth and an opposing second side having one of a second plurality of notches (42) and a second plurality of teeth. The first sprocket (30) defines the other of the first plurality of notches and the first plurality of teeth (44) and the secondary sprockets (32) define the other of the second plurality of notches and the second plurality of teeth (46). The first plurality of teeth (44) engage the first plurality of notches (40) and the second plurality of teeth (46) engage the second plurality of notches (42), whereby rotation of the first sprocket (30) about the axis of rotation engages the first plurality of teeth (44) with the first plurality of notches (40) and the second plurality of teeth (46) with the second plurality of notches (42). |
