Torsion bar stabilizing system for snowmobiles

Claim 2

In a power driven vehicle having a frame, a pair of laterally spaced steerable skis, and spring suspension means attaching said skis to said frame, an improvement comprising an antiroll torsion bar stabilizing system, comprising: a torsion bar attached to said frame, and means connecting each ski to said bar including a lever arm and means for connecting said lever arm to said bar, and means for connecting said ski to said lever arm including a link pivotally connected to and angling upwardly and laterally away from said skis; said linkage being operable to exert a twisting moment upon said bar in response to vertical Or horizontal displacement of said skis.

Claim 3

The device of claim 1 wherein said link is pivotally connected to sad ski.

Claim 4

The device of claim 1 wherein said lever arms are an integral extension of said bar.

Claim 5

The device of claim 1 wherein said spring means comprises leaf spring means and means for attaching said leaf spring means to said frame and said skis.

Claim 6

The device of claim 1 wherein said link is pivotally connected to said lever arm.

Claim 7

The device of claim 5 wherein said torsion bar comprises a generally linear main body and a pair of lever arms extending outwardly therefrom, and said connecting means comprises means for pivotally connecting said links respectively to said lever arms.

Claim 8

In a snowmobile having a body, a pair of skis, and means steerably attaching said skis to said body including leaf spring suspension means for said skis, and means to pivot said skis about a generally upright axis, an improved anti-roll torsion bar stabilizing system comprising, a torsion bar attached to said body, and means for operatively connecting each of said skis to said torsion bar including, a link for each ski and means for pivotally attaching each link to each ski at first pre-selected points, and means for attaching said links to said torsion bar at second pre-selected points; said second pre-selected points being offset laterally from said first pre-selected points and said generally upright axis, whereby said system is responsive to relative vertical and horizontal displacement of said skis through said leaf spring suspension means with respect to said axis and the snowmobile body.

Claim 9

In a snowmobile having a body, a pair of skis, and means steerably attaching said skis to said body including leaf spring suspension means for said skis, and means to pivot said skis about a generally upright axis, an improved anti-roll torsion bar stabilizing system comprising, a torsion bar attached to said body, and means for operatively connecting each of said skis to said torsion bar including, a link for each ski and means for pivotally attaching each link to each ski at first pre-selected points, and means for attaching said links to said torsion bar at second pre-selected points; said second pre-selected points being offset laterally from said first pre-selected points and said generally upright axis, whereby said system is responsive to relative vertical and horizontal displacement of said skis through said leaf spring suspension means with respect to said axis and the snowmobile body.
