  • Patent number: 6234263
    Abstract: A single seater snowmobile type recreational vehicle and a steering assembly for such as vehicle is described herein. The recreational vehicle includes a longitudinal frame, a suspension mounted to a rear portion of the frame, an endless track rotatably mounted to the suspension, an engine mounted to the frame and associated to the endless track to selectively rotate the endless track about the suspension thereby allowing displacement of the vehicle. The recreational vehicle also includes a steering assembly provided with a handlebar portion mounted to the frame and pivoting about a first pivot axis, a fork portion mounted to the frame and pivoting about a second pivot axis, a direction bar having a proximate end linked to the handlebar portion and a distal end linked to the fork portion, the direction bar being offset from the first and second pivot axis. A rotation of the handlebar portion thereby causes a rotation of the fork portion.

    Abstract: A rear suspension system for a land vehicle comprising a single generally centrally mounted structure in a middle portion of the rear suspension system. The suspension system comprises a pair of inclined primary suspension means, and a pair of inclined primary oscillating arms for pivotally connected to a pair of laterally spaced longitudinal slides at an underside area of the chassis of the land vehicle. Each of the primary oscillating arms comprise a distal end, which are further coupled to a horizontal bar adjacent a distal end of the primary suspension means, such as a shock absorber, and a proximal end which are individually mounted a horizontal bar adjacent a front end of the primary suspension means at an underside portion of the chassis. The suspension system further comprises a Weight Transfer Dynamic Compensator for raising a front tip portion of the longitudinal slides each time there is a transfer of weight in the vehicle.
