  • Vehicle transmission apparatus
    Patent number: 6454031
    Abstract: The ATV transmission includes an epicyclic arrangement, which serves as a drive-differential. One road wheel is geared to the planet-carrier or spider, and the other to the ring gear, while the engine drives the sun. An idler-gear between the ring and its road wheel means that the ring and the spider rotate in opposite senses, whereby a large gear ratio between the sun and the road wheels can be provided. Steering of the vehicle is provided, by driving the road wheels at different speeds. This is accomplished using a steer-differential, which is identical to the drive-differential; rotating the sun of the steer-differential imposes a corresponding differential speed on the road wheels.
