Abstract
A tracked ATV includes a frame, a track coupled to the frame, and a power source supported by the frame and drivingly coupled to the track. The tracked ATV further includes a steering and drive assembly, which has a first hydraulic pump coupled to the tracks for large radius turns. The steering and drive assembly also has a second hydraulic pump coupled to the tracks for small radius turns.
Claims24
A vehicle comprising:
- a plurality of ground engaging members, the plurality of ground engaging members including a track having a lower portion configured to engage a ground surface, an upper portion vertically spaced from the lower portion, a forward portion extending between the lower portion and the upper portion, an ultimate forward longitudinal end and an ultimate rearward longitudinal end;
- a frame supported by the plurality of ground engaging members;
- a suspension assembly positioned within an interior of the track;
- a seat for an operator supported by the frame, the seat having a rearward end between the ultimate forward longitudinal end and the ultimate rearward longitudinal end of the track;
- a steering input configured to rotate, the steering input supported by the frame and positioned forward of and laterally aligned with the seat;
- a drive unit rotatable about a drive unit rotational axis and extending within the interior of the track and profiled to engage only the upper portion and the forward portion of the track;
- a plurality of batteries supported by the plurality of ground engaging members, the plurality of batteries including a first battery positioned:
- longitudinally rearward of the ultimate forward longitudinal end of the track,
- longitudinally forward of the ultimate rearward longitudinal end of the track, and
- outside of the interior of the track;
- and
- an electric motor rotatable about an electric motor rotational axis and operatively coupled to plurality of batteries and operatively coupled to the drive unit to power movement of the track, the electric motor positioned longitudinally forward of the first battery of the plurality of batteries and the electric motor rotational axis of the electric motor is longitudinally offset relative to the drive unit rotational axis of the drive unit.
