Abstract

There is provided a saddle-ridden type vehicle. An oil cooler cools engine oil to be supplied to an engine. A supercharger compresses combustion air to be supplied to the engine. A water pump pumps cooling water to the engine and the supercharger. A cooling piping flows the cooling water delivered from the water pump. A first inlet piping supplies the cooling water to the oil cooler. A second inlet piping is disposed in parallel with the first inlet piping and supplies the cooling water to the supercharger. A first outlet piping extends upward from the oil cooler and returns the cooling water to the water pump. A second outlet piping extends upward from the supercharger and returns the cooling water to the water pump. The first outlet piping and the second outlet piping converge above the oil cooler and the supercharger.

Claims

1. A saddle-ridden type vehicle comprising:

an engine;

an oil cooler configured to cool engine oil to be supplied to the engine;

a supercharger configured to compress combustion air to be supplied to the engine;

a water pump configured to pump cooling water to the engine and the supercharger; and

a cooling piping configured to flow the cooling water delivered from the water pump,

wherein the cooling piping comprises;

a first inlet piping configured to supply the cooling water delivered from the water pump to the oil cooler;

a second inlet piping disposed in parallel with the first inlet piping and configured to supply the cooling water delivered from the water pump to the supercharger;

a first outlet piping extending upward from the oil cooler and configured to return the cooling water having cooled the oil cooler to the water pump; and

a second outlet piping extending upward from the supercharger and configured to return the cooling water having cooled the supercharger to the water pump, and

wherein the first outlet piping and the second outlet piping converge above the oil cooler and the supercharger.

2. The saddle-ridden type vehicle according to claim 1, wherein the cooling piping further comprises a convergence piping configured to converge the first outlet piping and the second outlet piping and connected to a circulation path of the cooling water positioned above the oil cooler and the supercharger.

3. The saddle-ridden type vehicle according to claim 2, further comprising:

a radiator configured to cool the cooling water;

a cooling water flow control unit disposed above the oil cooler and the supercharger and configured to regulate an amount of the cooling water to flow in the radiator in accordance with a temperature of the cooling water; and

a core piping configured to communicate the cooling water flow control unit and the water pump each other,

wherein the convergence piping is configured to communicate with the core piping via the cooling water flow control unit serving as the circulation path.

4. The saddle-ridden type vehicle according to claim 2, wherein an inner diameter of the convergence piping is made greater than an inner diameter of the first outlet piping and is made greater than an inner diameter of the second outlet piping.

5. The saddle-ridden type vehicle according to claim 1,

wherein the oil cooler is disposed at a front-lower side of the engine,

wherein the supercharger is disposed above the oil cooler, and

wherein the cooling piping is disposed at an inner side relative to a length of the engine in a vehicle width direction, as seen from the front, and is disposed at a rear side of a front end portion of the supercharger, as seen from a side.

6. The saddle-ridden type vehicle according to claim 1,

wherein the cooling piping further comprises a branched piping configured to branch a tip portion thereof extending from the water pump and connected to the first inlet piping and the second inlet piping, and

wherein an inner diameter of the branched piping is made greater than an inner diameter of the first inlet piping and is made greater than an inner diameter of the second inlet piping.
