A vehicle including a chassis; a seat; a motor; an endless drive track; a suspension assembly supporting the endless drive track. The suspension assembly includes at least one slide rail and at least one suspension arm pivotally connected to the slide rail and the chassis, the arm including a top bar extending laterally and a shock absorber. A first support assembly connecting a first end portion to a first chassis side and a second support assembly connecting a second end portion to a second chassis side. Each support assembly includes a bracket connected to the chassis at a top portion of the bracket; and a connector disposed on an end portion of the top bar, the connector including an arm portion, the end portion extending through a connector passage, and a flange portion defining a slot therein, a bottom portion of the bracket being received in the slot.

A damping control system for a vehicle having a suspension located between a plurality of ground engaging members and a vehicle frame are disclosed. The vehicle including at least one adjustable shock absorber having an adjustable damping characteristic.

A method for mounting a track assembly to a vehicle comprises: pivotally connecting a frame of the track assembly to a distal end portion of an A-arm of the vehicle for permitting rotation of the track assembly about a steering axis; inserting a fastener through a fastener aperture defined in the distal end portion of the A-arm; and fastening an anti-rotation device of the track assembly to the distal end portion of the A-arm with the fastener, the anti-rotation device being connected to the frame. A suspension and track assembly for a vehicle is also disclosed.

A dive-resistant suspension for a snow machine having a ski assembly and a body has a swing arm and a resilient member that biases the swing arm downward relative to the body. The swing arm has a first rigid linkage and a second rigid linkage. The first rigid linkage has a first pivot point connected to the body of the snow machine and a second pivot point connected to the ski column. The second rigid linkage has a first pivot point connected to the body of the snow machine and a second pivot point connected to the ski column. The swing arm defines a travel path of the ski assembly as the swing arm moves between an operative position and a retracted position. In a first portion of the travel path, the ski assembly moves from the operative position forward and up relative to the body of the snow machine.

A snowmobile has a frame having a motor module. The motor module has a front portion defining a cross member and further defining an aperture below the cross member. The frame further has a tunnel, a suspension module, a motor, a handlebar, front left and right skis both operatively connected to the handlebar and front left and right suspension assemblies operatively connecting the front left and right skis respectively to the suspension module and to the motor module. Each one of the front left and right suspension assemblies have a respective support arm having a proximal end positioned longitudinally forward of the motor module and a proximal fastener pivotally connecting the proximal end to the front portion of the motor module about a pivot axis. A line extending from a left pivot axis to a right pivot axis is contained in the cross member.

A snowmobile has a frame having a motor module, a tunnel connected to the motor module, a suspension module connected to the motor module, a motor, a handlebar, a ski operatively connected to the handlebar and a front suspension assembly operatively connecting the ski to the suspension module and to the motor module. The front suspension assembly has a suspension arm having a proximal end positioned longitudinally between the motor module and the suspension module. The proximal end pivots about a pivot axis extending through an interior portion of the suspension module. A proximal fastener passes through the proximal end of the suspension arm and extends from the interior portion of the suspension module to the motor module. The proximal fastener thereby pivotally connects the suspension arm to the suspension module and to the motor module about the pivot axis.

A jet-powered sled has a body having a control cockpit with control apparatus for an operator to control the jet sled, a set of surface runners adapted to engage a surface upon which the sled is operated, the surface runners removably engaged to spindles coupled to swing arms coupled to the jet sled, and an engine compartment having a jet engine removably mounted in a manner to direct thrust to a rear of the jet sled to propel the jet sled. The jet sled is characterized in that the sled may be adapted specifically to run on water, ice or snow by installing runners adapted for water, ice or snow on the spindles of the swing arms.

A leaning vehicle has a frame, a straddle seat, a motor, a shock tower pivotally connected the frame, the frame being pivotable relative to the shock tower, and front left and right suspension assemblies connected the frame. Each of the front left and right suspension assemblies comprises a leg operatively connected to a corresponding front left or right ground engaging member and being rotatable about a steering axis, an upper suspension arm having a first end pivotally connected to the frame and a second end pivotally connected to the leg, a lower suspension arm having a first end pivotally connected to the frame and a second end pivotally connected to the leg and a shock absorber having an upper end connected to the shock tower and a lower end connected to the lower suspension arm and a brake assembly connected to the frame and the shock tower.

This specification relates to a snowmobile. Each of the right suspension and the left suspension includes a damper capable of expanding and contracting according to the vertical movement of the lower arm and a spring that exerts spring force in the expansion/contraction direction of the damper. The cylinder of the right damper and the cylinder of the left damper are connected to each other through a hydraulic fluid channel so that the hydraulic fluid flows between the cylinder of the right damper and the cylinder of the left damper. This snowmobile can reduce the difference in contact pressure on snow surface between the left ski and the right ski, when the vehicle turns.

A vehicle comprises a chassis, a seat, an endless drive track, a rear suspension assembly with at least one slide rail and a substantially inextensible limiter strap extending between the chassis and the at least one slide rail, to limit separation between the at least one slide rail and the chassis. The strap holder is moveable between a first holder position and a second holder position, a position of the end of the limiter strap being different in the first strap holder position compared to the second strap holder position. A control cable is operatively connects the strap holder to a strap adjustment actuator. The strap adjustment actuator is disposed forward of the seat and is operable by a user during operation of the vehicle, the strap adjustment actuator being movable between first and second positions related to the positions of the strap holder.
