There is provided a singly steerable, serpentine steel track crawler. The single-track crawler can steer independently in a serpentine fashion. Two or more single crawler tracks side-by-side can be transformed into a multi-track crawler vehicle. The single-track crawler or multi-track crawler vehicle can be fitted with rubber tires for plying on paved roads. This makes it a versatile, multi-terrain vehicle for agriculture and earth-moving applications.

A snow vehicle, comprising a frame (102, 202), and to the frame (102, 202) operationally connected track system for moving the snow vehicle on the snow, which track system comprises a track (110, 210), and a slide rail (216) for slid-ing of the track, the snow vehicle further comprising a suspension structure (120) for attenuating impacts to the track system of the snow vehicle, which suspension system (120) comprises one or more suspension members (128). The suspension member (128) it at least partially arranged in the space between the track (110) and the frame (102).

A snowmobile including a chassis including a tunnel; a motor; at least one ski; an endless drive track; a rear suspension assembly including: a front suspension arm; a rear suspension arm; a pair of slide rails; a first rear shock absorber connected between the front suspension arm and the slide rails; and a second rear shock absorber connected between the rear suspension arm and the front suspension arm or the slide rails; at least one sensor for sensing an angular position of the front suspension arm or the rear suspension arm relative to one of the tunnel and a component of the rear suspension assembly near at least one of the front suspension arm and the rear suspension arm; and a controller communicatively connected to the sensor to receive electronic signals therefrom representative of the angular position.

A vehicle has a frame, a ski, an endless track, a motor, a rear suspension assembly supporting the endless track, and a continuously variable transmission operatively connecting the motor to the endless track for driving the endless track. The continuously variable transmission has a primary pulley operatively connected to the motor, a transmission belt, and a secondary pulley operatively connected to the primary pulley via the transmission belt. The secondary pulley is operatively connected to the endless track. The continuously variable transmission is positioned forwardly of the motor.

A snowmobile has a suspension with a spring. The spring has a central loop portion and an elastomeric bushing disposed in the central loop portion. A limiting cable is disposed adjacent to the spring. The snowmobile also has a rear snowmobile suspension with a torsion link structure. A control arm is pivotally connected to a first end of the torsion link structure. A wheel assembly is pivotally connected to a second end of the torsion link structure. A first slide rail is attached to the wheel assembly with a sliding mechanism. A track around the rear snowmobile suspension has a paddle oriented substantially perpendicular to the track. A first gripping element is disposed on the face of the paddle.
