Suspension systems for a vehicle
A utility vehicle is disclosed. The utility vehicle may include storage areas under the dash. The utility vehicle may include suspension systems for utility vehicles having shocks with both a fluidic stiffness adjustment and a mechanical stiffness adjustment. The utility vehicle may include an electrical power steering.
1. A vehicle comprising:
a frame;
a power source supported by the frame;
seating supported by the frame, the seating having at least one seat bottom surface and at least one seat back surface;
an operator area adapted for use by a vehicle operator when the vehicle is in motion, the at least one seat bottom surface and the at least one seat back surface being positioned within the operator area;
a roll cage supported by the frame and positioned to protect the operator area;
a plurality of ground engaging members supporting the frame above the ground, the plurality of ground engaging members including at least two front ground engaging members positioned forward of the operator area and at least two ground engaging members located rearward of the operator area, wherein at least one of the plurality of ground engaging members are operatively coupled to the power source to propel the vehicle relative to the ground;
a CVT supported by the frame, the power source being operatively coupled to at least one of the plurality of ground engaging members through the CVT to provide power from the power source to the at least one of the plurality of ground engaging members;
a front suspension coupling a first ground engaging member of the at least two front ground engaging members to the frame, the front suspension including a shock; and
a rear suspension coupling a first ground engaging member of the at least two rear ground engaging members to the frame, the rear suspension includes a load leveling shock, wherein the load leveling shock is a self leveling shock which wants to stay at a first length and wherein when a load is placed on a cargo carrying surface of a rear portion of the vehicle positioned above the self leveling shock the self leveling shock is shortened and enters a pumping zone to pump fluid into a chamber within the self leveling shock resulting in the length of the self leveling shock returning towards the first length.
2. The vehicle of claim 1 , wherein the shock of the front suspension is an adjustable, non-load leveling shock.
3. The vehicle of claim 1 , wherein the shock includes an adjustable fluidic stiffness and an adjustable mechanical stiffness.
4. The vehicle of claim 1 , wherein the cargo carrying surface is part of a bed supported by the frame and positioned above the self leveling shock.
5. A vehicle comprising:
a frame;
a power source supported by the frame;
seating supported by the frame, the seating having at least one seat bottom surface and at least one seat back surface;
an operator area adapted for use by a vehicle operator when the vehicle is in motion, the at least one seat bottom surface and the at least one seat back surface being positioned within the operator area;
a roll cage supported by the frame and positioned to protect the operator area;
a plurality of ground engaging members supporting the frame above the ground, the plurality of ground engaging members including at least two front ground engaging members positioned forward of the operator area and at least two ground engaging members located rearward of the operator area, wherein at least one of the plurality of ground engaging members are operatively coupled to the power source to propel the vehicle relative to the ground;
a CVT supported by the frame, the power source being operatively coupled to at least one of the plurality of ground engaging members through the CVT to provide power from the power source to the at least one of the plurality of ground engaging members;
a front suspension coupling a first ground engaging member of the at least two front ground engaging members to the frame, the front suspension including a shock;
a rear suspension coupling a first ground engaging member of the at least two rear ground engaging members to the frame, the rear suspension includes a load leveling shock; and
a bed supported by the frame and positioned above the self leveling shock, wherein the load leveling shock is a self leveling shock which wants to stay at a first length and wherein when a load is placed in the bed the self leveling shock is shortened and enters a pumping zone to pump fluid into a chamber within the self leveling shock resulting in the length of the self leveling shock returning towards the first length.
6. The vehicle of claim 5 , wherein when the load is removed from the bed the self leveling shock is lengthened and pressure is bled off to return the self leveling shock towards the first length.
7. The vehicle of claim 5 , wherein the power source is positioned rearward of a front plane of the seating.
8. A vehicle comprising:
a frame;
a power source supported by the frame;
seating supported by the frame, the seating having at least one seat bottom surface and at least one seat back surface;
an operator area adapted for use by a vehicle operator when the vehicle is in motion, the at least one seat bottom surface and the at least one seat back surface being positioned within the operator area;
a roll cage supported by the frame and positioned to protect the operator area;
a plurality of ground engaging members supporting the frame above the ground, the plurality of ground engaging members including at least two front ground engaging members positioned forward of the operator area and at least two ground engaging members located rearward of the operator area, wherein at least one of the plurality of ground engaging members are operatively coupled to the power source to propel the vehicle relative to the ground;
a CVT supported by the frame, the power source being operatively coupled to at least one of the plurality of ground engaging members through the CVT to provide power from the power source to the at least one of the plurality of ground engaging members;
a front suspension coupling a first ground engaging member of the at least two front ground engaging members to the frame, the front suspension including a shock;
a rear suspension coupling a first ground engaging member of the at least two rear ground engaging members to the frame, the rear suspension includes a self leveling shock; and
a bed supported by the frame and positioned above the self leveling shock, wherein the bed is rotatably coupled to frame.
9. The vehicle of claim 1 , wherein the power source is positioned rearward of a front plane of the seating.
10. The vehicle of claim 1 , further comprising a front differential and a rear differential, the front differential operatively coupling at least one of the front ground engaging members to the CVT and the rear differential operatively coupling at least one of the rear ground engaging members to the CVT.
11. The vehicle of claim 10 , further comprising a bed supported by the frame and positioned above the self leveling shock.
12. The vehicle of claim 11 , wherein the power source is positioned rearward of a front plane of the seating.
