Abstract

A saddle-ridden vehicle includes: an engine; a clutch which enables or disables motive power transmission between a crankshaft provided in the engine and a transmission mechanism; a turbocharger which compresses air for burning to be supplied to the engine; and a throttle device which adjusts a rate of air supply to the engine by controlling an opening angle of a throttle valve using a drive motor, the turbocharger includes a turbine unit which is driven by exhaust gas of the engine and a compressor unit which compresses air receiving drive force of the turbine unit; the clutch is disposed at one side, in a vehicle width direction, of the engine; and the compressor unit and the drive motor are disposed at the other side of the engine in the vehicle width direction.

Claims

1. A straddled saddle vehicle comprising:

an engine;

a clutch which enables or disables motive power transmission between a crank shaft provided in the engine and a transmission mechanism;

a turbocharger which compresses air for burning to be supplied to the engine; and

a throttle device which adjusts a rate of air supply to the engine by controlling an opening angle of a throttle valve using a drive motor, wherein;

the turbocharger comprises a turbine unit which is driven by exhaust gas of the engine and a compressor unit which receives a drive force of the turbine unit to compress air;

the clutch is disposed at one side, in a vehicle width direction, of the engine; and

the compressor unit and the drive motor are disposed at the other side of the engine in the vehicle width direction.

2. The straddled saddle vehicle according to claim 1, wherein:

the turbocharger is disposed in front of the engine; and

the drive motor is disposed in the rear of the engine.

3. The straddled saddle vehicle according to claim 2, wherein:

the engine comprises a cylinder which is erected from a top portion of a crank case which houses the crank shaft;

the turbocharger is disposed in front of the cylinder; and

the clutch and the drive motor are disposed in the rear of the cylinder.

4. The straddled saddle vehicle according to claim 3, wherein:

the straddled saddle vehicle further comprises an exhaust pipe which is connected to the turbine unit and discharges the exhaust gas of the engine to the outside;

the turbine unit is disposed adjacent to a central portion, in the vehicle width direction, of the engine;

the compressor unit is disposed at the other side of the turbine unit in the vehicle width direction; and

the exhaust pipe is disposed at one side of the turbine unit in the vehicle width direction.

5. The straddled saddle vehicle according to claim 2, wherein:

the straddled saddle vehicle further comprises an exhaust pipe which is connected to the turbine unit and discharges exhaust gas of the engine to the outside;

the turbine unit is disposed adjacent to a central portion, in the vehicle width direction, of the engine;

the compressor unit is disposed at the other side of the turbine unit in the vehicle width direction; and

the exhaust pipe is disposed at one side of the turbine unit in the vehicle width direction.

6. The straddled saddle vehicle according to claim 1, wherein:

the straddled saddle vehicle further comprises an exhaust pipe which is connected to the turbine unit and discharges the exhaust gas of the engine to the outside;

the turbine unit is disposed adjacent to a central portion, in the vehicle width direction, of the engine;

the compressor unit is disposed at the other side of the turbine unit in the vehicle width direction; and

the exhaust pipe is disposed at one side of the turbine unit in the vehicle width direction.
