Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle engine mounted on, for example, a four-wheeled vehicle.

[0002]

2. Description of the Related Art For example, in a four-wheeled vehicle, an engine is mounted in a front engine compartment, and this engine has a clutch and a transmission arranged on one side of an engine body. This engine can be mounted vertically or horizontally. For example, if the engine is mounted vertically in a rear-wheel drive vehicle,
The power is transmitted from the transmission located on the rear side of the engine body to the differential through the propeller shaft, and the power is transmitted from the differential to the left and right rear wheels for driving.

Further, for example, when an engine is laterally mounted on a front-wheel drive vehicle, power is differentially transmitted from a transmission arranged on the side of the engine body, and the power is transmitted from the differential to the left and right front wheels. Drive.

[0004]

By the way, in the engine of such a vehicle, since the clutch is arranged close to the transmission on one side of the engine body, the transmission capacity of the clutch is affected by the thermal influence of the transmission. There is a problem that it drops.

Further, for example, in a vertically installed engine, the engine body, the clutch and the transmission are arranged in the front-rear direction of the vehicle body, so that the clutch and the transmission arranged on the rear side of the engine body get into the feet of the driver's cab, It is difficult to secure the foot space. For this reason, when the engine is moved to the front side, there is a problem that the engine hood becomes higher by that amount.

Further, for example, in a horizontal engine, the engine body, the clutch, and the transmission are arranged in the left-right direction of the vehicle body, and the clutch and the transmission are located on one side of the engine body. Deviating from
The weight could not be evenly distributed to the left and right front wheels.

The present invention has been made in view of the above circumstances, and an object thereof is to provide an engine of a vehicle which can improve transmission power of a clutch and can be properly mounted in a vertical or horizontal position.

[0008]

In order to solve the above-mentioned problems, an engine of a vehicle according to the present invention has an intermediate shaft arranged substantially parallel to a crankshaft in an engine body, and the crankshaft is provided on one side of the engine body. A clutch for transmitting the power from the intermediate shaft to the intermediate shaft is arranged, and a transmission for changing the power from the intermediate shaft is arranged on the other side of the engine body.

[0009]

In the present invention, the clutch is located on one side of the engine body and the transmission is located on the other side, and the clutch is located away from the transmission. Therefore, the clutch is prevented from being affected by the heat of the transmission. It

Further, in a vertically installed engine, for example, by arranging the clutch on the front side with respect to the engine body, the transmission can be moved to the front side by that amount, and it is easy to secure a space at the foot of the driver's cab. Become. Moreover, since the clutch located on the front side is lower than the engine body, the engine hood can be lowered.

Further, for example, in a horizontal engine, the clutch is located on one side of the engine body and the transmission is located on the other side, and the clutch and the transmission are arranged on the left and right sides of the engine body. It can be aligned with the center, and the weight can be evenly distributed to the left and right of the vehicle body.
