Abstract:
Reverse gear for a motor vehicle transmission is achieved through a chain assembly having two sprockets and a multi-link chain. One of the sprockets is coupled to a clutch which selectively connects it to an input or output shaft. The other sprocket is directly coupled to the other, i.e., output or input shaft. The multi-link chain carries drive torque from the input shaft to the output shaft when the clutch is engaged. Because the other driving connections between the input shaft and the output shaft associated with the forward gears or gear ratios are through gears which cause a reversal of rotational direction, the driving connection achieved by the chain assembly, without a directional reversal, is, in fact, opposite in direction to the rotational direction of the forward gears, thereby providing reverse.
