PURPOSE:To improve rear wheel steering property by providing constitution of giving a steering input to a first differential gear and transmitting a forward output from the first differential gear to a second differential gear and a reverse output through a reverse gear to the second differential gear for utilizing the output of the second differential gear for rear wheel steering. CONSTITUTION:A steering input A is input through a hub H to a first differential gear D to be divided into two directions therewith. One forward input enters a second differential gear D to be drawn out as a steering output B of forward output and the other enters the second differential gear D through a reverse gear G as a reverse input to be drawn out as a steering output B of reverse output. Assuming 40km/h as phase boundary for example, the reverse input exceeds the forward input in the second differential gear D in at most 40km/h, so that the exceeding amount is drawn out as the reverse output to steer rear wheels. On the other hand, the forward output exceeds the reverse output in at least 40km/h, so that the exceeding amount is drawn out as the forward output to steer the rear wheels. |
