Abstract
A snowmobile ski suspension system for increasing the overall performance and adjustability of a snowmobile front suspension. The snowmobile ski suspension system includes a collar member attached to the chassis of the snowmobile, a torsion spring attached about the collar member, a first arm extending radially from the torsion spring engaging the ski support structure, a second arm extending radially from the torsion spring, and an adjustment member attached to the second arm for allowing adjustment of the stiffness of the torsion spring. The first arm may be attached at various locations along the ski support structure in various manners.
Claims21
A snowmobile ski suspension system having at least one suspension arm extending from a chassis and an end support member attached to said at least one suspension arm for supporting a ski, comprising:
- a torsion spring attached to said chassis;
- and
- a first arm radially extending from said torsion spring, wherein said first arm is attached to said end support member;
- wherein an end of said torsion spring opposite of said first arm is non-movably attached to said chassis.
A snowmobile ski suspension system having at least one suspension arm extending from a chassis and an end support member attached to said at least one suspension arm for supporting a ski, comprising:
- a torsion spring attached to said chassis;
- and
- a first arm radially extending from said torsion spring, wherein said first arm is attached to said at least one suspension arm;
- wherein an end of said torsion spring opposite of said first arm is non-movably attached to said chassis.
A snowmobile ski suspension system having at least one suspension arm extending from a chassis, comprising:
- a torsion spring having a coiled section, a first arm extending from said coiled section, and a second arm extending from said coiled section opposite of said first arm;
- wherein said second arm is attached to said chassis;
- and
- wherein said first arm is attached to said at least one suspension arm applying a continuous downward force upon said first arm.
A snowmobile ski suspension system having at least one suspension arm extending from a chassis, comprising:
- a torsion spring attached to said chassis, wherein said torsion spring movably surrounds a collar member attached to said chassis;
- and
- a first arm radially extending from said torsion spring, wherein said first arm is attached to said at least one suspension arm.
A snowmobile ski suspension system having at least one suspension arm extending from a chassis, comprising:
- a torsion spring attached to said chassis;
- a first arm radially extending from said torsion spring, wherein said first arm is attached to said at least one suspension arm;
- a second arm radially extending from said torsion spring;
- and
- an adjustment mechanism attached to said second arm for allowing rotational adjustment of said second arm thereby increasing or decreasing said torsion of said torsion spring.
