초록 ▼

A snowmobile includes a chassis having a generally reduced length and a snow flap pivotally attached to the rear portion of the chassis, above the track system. The track system extends rearwardly beyond the chassis, and the snow flap shields the track system above and behind from spraying snow. The snow flap is linked to the track system so that as the track system moves through a range of travel relative to the chassis, the snow flap pivots relative to the chassis with the track system. This configuration prevents damaging contact between the tread and the undersurface of the snow flap and/or the chassis. The reduced length of the chassis decreases the weight of the snowmobile and the polar moment of inertia, thereby improving turning performance. A bumper extends from the snow flap and can be used to lift the rear of the snowmobile more easily.

1. A snowmobile, comprising:a chassis including an inverted U-shaped tunnel;a radiator within the tunnel;a handlebar disposed on said chassis;a ski support system mounted at a forward portion of said chassis and including at least two skis operatively connected to said handlebar to provide steering control of said snowmobile;a propulsion-providing track system having an endless track, said track system being movably mounted under a rear portion of said tunnel and configured to move through a range of travel with respect to said tunnel; anda snow flap disposed above said track system, said snow flap being connected to said track system at a rear end thereof, and said snowflap being directly pivotally connected to said rear portion of said tunnel at a front end thereof, said snow flap moving with said track system as said track system moves through said range of travel and guiding snow sprayed from said endless track onto said radiator. 2. The snowmobile according to claim 1, wherein said snow flap extends rearwardly beyond said track system and terminates in a depending portion disposed behind said track system, wherein said snow flap prevents or substantially reduces the amount of snow being sprayed up from or behind said snowmobile by said track system. 3. The snowmobile according to claim 1, further comprising a handle-shaped bumper member extending from said snow flap. 4. The snowmobile according to claim 1, wherein said snow flap has skirt members depending from sides thereof. 5. The snowmobile of claim 4, wherein said snow flap comprises an upper snow guard portion and wherein said skirt members are attached to said upper snow guard portion. 6. The snowmobile of claim 4, wherein said snow flap comprises an upper snow guard portion and said skirt members are integrally formed with said upper snow guard portion. 7. The snowmobile of claim 1, wherein said track system further comprises support/guide wheels about which said endless track rotates and wherein said snow flap is connected to said track system via linkage struts pivotally connected to an axle on which said support/guide wheels are carried.
