Patent ID: 8827291

Claim:
A snowmobile suspension assembly including: a snowmobile chassis supported on opposite sides of the longitudinal centerline of the chassis by a set of steerable skis or other surface engaging directional devices; said steerable skis being operatively suspended from opposite sides of the chassis wholly or in part by means of pressurized air springs; said pressurized air springs incorporating internal air chambers capable of providing extension forces; a conduit means that permits connecting the internal air pressure of the air chamber on one side of said longitudinal centerline to the internal air pressure of the air chamber on the opposite side of said longitudinal centerline; said conduit arranged to permit continuous connection between said air chambers even while the steerable skis become steered; the conduit connection between the air chambers providing means for sharing air pressure from either of the air chambers with the air chamber on opposite side of said longitudinal centerline; said air pressure sharing permitting a reduction in resistance to chassis roll when steering.
