    摘要: A transmission comprising an input shaft connectable to a power generation device such that the input shaft is rotatable at a power input rotational speed, an output shaft connectable to a driveline of the vehicle, and a plurality of gear sets selectable to operably connect the input shaft to the output shaft providing a rotational speed reduction ratio therebetween. The gear sets comprise a master active gear set having a master gear ratio, a slave active gear set having a slave gear ratio, and a passive gear set having a passive gear ratio. The passive gear set is operable to selectively engage the master and slave active gear sets to provide the high numeric compound ratio rotational speed reduction that is the product of the master active gear ratio, the slave active gear ratio and the passive gear ratio.

    摘要: An all-terrain vehicle is provided comprising a chassis, four wheels and a passenger compartment that includes a passenger seating structure. The vehicle additionally comprises a drivetrain operatively connected to at least one of the wheels comprising at least one drive shaft and at least one torque transfer device. Furthermore the vehicle includes a prime mover that is mounted to the chassis entirely forward of a front edge of the seating structure and operatively connected to the drivetrain. The prime mover is structured and operable to provide motive force to at least one of the wheels.
