Abstract

The present invention relates to all terrain vehicles having at least a pair of laterally spaced apart seating surfaces. More particularly, the present invention relates to trail compliant side-by-side all terrain vehicles.

First claim

What is claimed is:

1. An all-terrain vehicle comprising:
a pair of front wheels;
a pair of rear wheels spaced apart from the front wheels by a wheelbase distance;
a frame supported by the pair of front wheels and the pair of rear wheels;
a pair of laterally spaced-apart seating surfaces supported by the frame between the pair of front wheels and the pair of rear wheels, the laterally spaced-apart seating surfaces including an upward facing driver seating surface and an upper driver seating surface positioned on a driver side of a longitudinal center line of the all-terrain vehicle and an upward facing passenger seating surface and an upper passenger seating surface positioned on a passenger side of the longitudinal center line of the all-terrain vehicle;
a drivetrain assembly comprising:
an engine positioned rearward of the laterally spaced-apart seating surfaces, the upward facing driver seating surface positioned vertically lower than a upper portion of the engine;
a continuously variable transmission operatively coupled to the engine and positioned rearward of the laterally spaced-apart seating surfaces; and
a differential operatively coupled to the engine through the continuously variable transmission;
an intake assembly comprising a first inlet port fluidly coupled to the continuously variable transmission and a second inlet port fluidly coupled to the engine, and at least one of the first inlet port and the second inlet port is positioned rearwardly and at least partially laterally aligned with at least one of the upper driver seating surface and the upper passenger seating surface, and each of the first inlet port and the second inlet port is positioned vertically higher than the upper portion of the engine; and
an exhaust assembly fluidly coupled to the engine, comprising:
a muffler; and
an exhaust conduit extending between the engine and the muffler, the muffler positioned along the longitudinal center line of the all-terrain vehicle and extending longitudinally rearward of the engine.

2. The all-terrain vehicle of claim 1 , wherein the muffler is positioned vertically above the differential.

3. The all-terrain vehicle of claim 1 , further comprising a three position mounting system which mounts the drivetrain assembly to the frame, the three point mounting system includes a first mount positioned on the driver side of the longitudinal center line of the all-terrain vehicle, a second mount positioned on a passenger side of the longitudinal center line of the all-terrain vehicle, and a third mount positioned rearward of the first mount and the second mount; the first mount and the second mount positioned on the lower side of the drivetrain assembly proximate the engine of the drivetrain assembly and the third mount is positioned on an upper side of the drivetrain assembly proximate the differential of the drivetrain assembly.

4. The all-terrain vehicle of claim 1 , wherein the engine is positioned completely behind the upward facing driver seating surface.

5. The all-terrain vehicle of claim 1 , further comprising a protective panel positioned between the pair of laterally spaced-apart seating surfaces and the engine.

6. The all-terrain vehicle of claim 1 , wherein both of the first inlet port and the second inlet port are positioned rearwardly of the upper driver seating surface.

7. The all-terrain vehicle of claim 1 , further comprising an engine cover positioned vertically above the engine and at least partially rearwardly of the upper driver seating surface, and at least one of the first inlet and the second inlet are positioned vertically above the engine cover.
