Abstract
A vehicle includes a plurality of ground-engaging members, a frame assembly supported by the ground-engaging members, and a powertrain assembly supported by the frame. The powertrain assembly includes at least an engine. The vehicle further includes a cooling assembly fluidly coupled to at least the engine and which includes a radiator and at least one fan positioned rearward of the radiator and angled relative to the radiator. A rear shroud is positioned between the radiator and fan and includes an air bypass assembly to exhaust air thought he rear shroud at higher speeds of the vehicle.
Claims38
A vehicle, comprising:
- a plurality of ground-engaging members;
- a frame assembly supported by the ground-engaging members;
- a powertrain assembly supported by the frame and including at least an engine;
- and
- a cooling assembly fluidly coupled to at least the engine and including a radiator and at least one fan positioned rearward of the radiator;
- a rear shroud positioned intermediate the radiator and the at least one fan;
- and
- an air bypass assembly integrated with the rear shroud, the air bypass assembly comprising a bypass opening formed in the rear shroud, a bypass flap coupled over the bypass opening by way of a hinge, and a mechanical control system coupled between the bypass flap and the rear shroud whereby the mechanical control system maintains the bypass flap in a normally spring loaded and shut position until the speed of the vehicle is greater than a speed V.
A vehicle, comprising:
- a plurality of ground-engaging members;
- a frame assembly supported by the ground-engaging members;
- a powertrain assembly supported by the frame and including at least an engine;
- a cooling assembly fluidly coupled to at least the engine and including a radiator and at least one fan positioned rearward of the radiator;
- a rear shroud positioned intermediate the radiator and the fan wherein the rear shroud has a curved shape rear wall extending between the radiator and the at least one fan;
- and
- an air bypass assembly integrated with the rear shroud, the air bypass assembly comprising a bypass opening formed in the rear shroud, a bypass flap coupled over the bypass opening by way of a hinge, whereby the bypass flap is normally in a shut position, wherein the bypass opening is positioned in the rear wall at a position above the fan.
