Abstract
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.
Claims25
A shock, comprising:
- a first body member supporting a first piston and having a first stop member;
- a second body member having a second stop member, the second body member being received in an interior of the first body member and the first piston being received in an interior of the second body member, the second body member including a second piston received in the first body member;
- a spring being compressed between the first stop member of the first body member and the second stop member of the second body member, at least one of the first stop member and the second stop member being moveable relative to the respective one of the first body member and the second body member;
- and
- an air inlet member being in fluid communication with the interior the second body member.

A shock, comprising:
- a first body member supporting a first piston and having a first stop member;
- a second body member having a second stop member, the second body member being received in an interior of the first body member and the first piston being received in an interior of the second body member, the second body member including a second piston received in the first body member;
- a spring being compressed between the first stop member of the first body member and the second stop member of the second body member, at least one of the first stop member and the second stop member being moveable relative to the respective one of the first body member and the second body member;
- and
- an air inlet member being in fluid communication with the interior the second body member, wherein the second stop member is moveable relative to the second body member to adjust the compression of the spring between the first stop member and the second stop member and the second stop member is a ring having a threaded internal surface which engages with a threaded external surface of the second body member.

A shock, comprising:
- a first body member supporting a first piston and having a first external stop member;
- a second body member having a second external stop member, the first piston being received in an interior of the second body member;
- an air inlet member being in fluid communication with the interior the second body member;
- and
- a spring being compressed between the first external stop member of the first body member and the second external stop member of the second body member, wherein a stiffness of the shock is adjustable both by changing an air pressure in the interior of the second body member by adding air in fluid communication with a first end of the first piston to the interior of the second body member through the air inlet and changing a separation of the first external stop member and the second external stop member.

A shock, comprising:
- a first body member supporting a first piston and having a first stop member;
- a second body member having a second stop member, the second body member being received in an interior of the first body member and the first piston being received in an interior of the second body member, the second body member including a second piston received in the first body member;
- a spring being compressed between the first stop member of the first body member and the second stop member of the second body member, at least one of the first stop member and the second stop member being moveable relative to the respective one of the first body member and the second body member;
- and
- an air inlet member being in fluid communication with the interior the second body member, wherein the first piston comprises a plurality of apertures permitting air in the second body to pass therethrough.

A shock, comprising:
- a first body member supporting a first piston and having a first external stop member;
- a second body member having a second external stop member, the first piston being received in an interior of the second body member;
- an air inlet member being in fluid communication with the interior the second body member;
- and
- a spring being compressed between the first external stop member of the first body member and the second external stop member of the second body member, wherein a stiffness of the shock is adjustable both by changing an air pressure in the interior of the second body member and changing a separation of the first external stop member and the second external stop member, wherein the first piston comprises a plurality of apertures permitting air in the second body to pass therethrough.
2 more elements
A shock, comprising:
- a first body member supporting a first piston and having a first external stop member;
- a second body member having a second external stop member, the first piston being received in an interior of the second body member and being positioned at a first end of the first body member which is also received within the interior of the second body member;
- an air inlet member being in fluid communication with the interior the second body member;
- and
- a spring, the first external stop member engaging a first end of the spring and the second external stop member engaging a second end of the spring, the spring being compressed between the first external stop member of the first body member and the second external stop member of the second body member, wherein a stiffness of the shock is adjustable both by changing an air pressure in the interior of the second body member and changing a separation of the first external stop member and the second external stop member.
