Abstract
A vehicle includes a frame supporting an engine, a transmission including an input shaft and an output shaft, a driving device linked to the output shaft so that power is transmitted therebetween, and a supercharger including a rotation shaft linked to the output shaft so that power is transmitted therebetween. The supercharger is fixed to the frame.
Claims19
A vehicle comprising:
- an internal combustion engine including a crankshaft;
- a frame supporting the internal combustion engine;
- a transmission including an input shaft linked to the crankshaft to transmit power therebetween, and an output shaft linked to the input shaft and that rotates at a rotational speed lower than a rotational speed of the input shaft;
- a driving device linked to the output shaft to transmit power therebetween and to generate a driving power;
- and
- a supercharger including a rotation shaft linked to the output shaft to transmit power therebetween and to compress air and supply the compressed air to the internal combustion engine;
- wherein
- the transmission is a continuously variable transmission or a stepped transmission;
- a transmission ratio of the transmission is changeable during operation of the transmission;
- and
- the supercharger is fixed to the frame without the engine interposed therebetween;
- and
- wherein the output shaft includes a driving device link portion linked to the driving device, and a supercharger link portion linked to the rotation shaft of the supercharger;
- and
- wherein the driving device link portion is located between the supercharger link portion along the output shaft and the transmission.

A snowmobile comprising:
- an internal combustion engine including a crankshaft;
- a frame supporting the internal combustion engine;
- a transmission including an input shaft linked to the crankshaft to transmit power therebetween, and an output shaft linked to the input shaft and that rotates at a rotational speed lower than a rotational speed of the input shaft;
- a driving device linked to the output shaft to transmit power therebetween and to generate a driving power;
- and
- a supercharger including a rotation shaft linked to the input shaft or to the output shaft to transmit power therebetween and to compress air and supply the compressed air to the internal combustion engine;
- wherein
- a transmission ratio of the transmission is changeable during operation of the transmission;
- the supercharger is fixed to the frame without the engine interposed therebetween;
- the supercharger is located above the internal combustion engine;
- and
- wherein the output shaft includes a driving device link portion linked to the driving device, and a supercharger link portion linked to the rotation shaft of the supercharger;
- and
- wherein the driving device link portion is located between the supercharger link portion along the output shaft and the transmission.
