摘要： A suspension system for a snowmobile has a rail for engagement with an endless drive track, and first and second suspension arms having upper ends adapted for pivotally connecting to the chassis and lower ends pivotally connected to the rail. The upper end the second suspension arm includes a shaft. A first shock absorber is operatively pivotally connected between the first suspension arm and the rail. A second shock absorber is operatively pivotally connected between the rail and the second suspension arm. Left and right brackets are connected to the shaft on either side of the second shock absorber. The shaft has a bent portion between the left and right brackets.

摘要： A rear suspension assembly for a snowmobile has a front suspension arm, a rear suspension arm, a pair of slide rails, at least one shock absorber, and at least one suspension coupler. The at least one suspension coupler couples the rear suspension arm with the front suspension arm. The at least one suspension coupler generates a coupling force to continuously couple the front and rear suspension arms with each other during a full range of movement between the fully extended position and the fully compressed position. A snowmobile having the rear suspension assembly is also disclosed.

摘要： A suspension assembly for a snowmobile comprises first and second suspension arms pivotally connected to a chassis and to a rail, and extending forwardly and upwardly from the rail. A bracket arm is fixedly connected to the first suspension arm. A link is pivotally connected to the bracket arm. A first shock absorber is pivotally connected to the first suspension arm and to the rail. The lower end of the first shock absorber is disposed forwardly of the lower end of the first suspension arm. A second shock absorber is pivotally connected to the link and to second suspension arm. The lower end of the second shock absorber is disposed rearwardly of the lower end of the first shock absorber. A tie rod is pivotally connected to the link, and to the second suspension arm. A snowmobile having such suspension system is also disclosed.

摘要： A snowmobile including a frame; at least one ski; an engine with an engine air inlet and an exhaust outlet; a turbocharger including an exhaust turbine, and a compressor. An air intake system includes a first flow path connecting the compressor to the atmosphere; a second flow path connecting the compressor to the engine air inlet; an intake bypass flow path connecting atmosphere to the engine air inlet for bypassing the compressor; and an intake bypass valve for controlling the flow through the intake bypass flow path. An exhaust system includes a third flow path connecting the exhaust outlet to the exhaust turbine; a fourth flow path connecting the exhaust turbine to the atmosphere; an exhaust bypass flow path connecting the exhaust outlet to the atmosphere for at least partially bypassing the exhaust turbine; and an exhaust bypass valve for controlling the flow through the exhaust bypass flow path.
