Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for connecting an engine and an auxiliary machine in an automobile in which an engine and a power transmission device are arranged in series.

[0002]

2. Description of the Related Art A power transmission device (that is, a clutch or a clutch and a transmission, etc.) driven by an engine is often arranged in series with the engine as disclosed in, for example, Japanese Patent Laid-Open No. 5-58171. . The term "series arrangement" as used herein means that the engine and the power transmission device are arranged such that the drive shaft of the engine and the input shaft of the power transmission device are located on a substantially straight line.

On the other hand, an auxiliary machine driven by an engine (that is, an alternator, a power steering pump, an air conditioner pump, etc.) is generally an auxiliary machine drive output on the side opposite to the output end of the engine drive shaft on the power transmission device side. It is designed to be connected to the end.

[0004]

Therefore, in an automobile in which the engine and the power transmission device are arranged in series as described above, a space for disposing the engine and the power transmission device including the above-mentioned auxiliary machinery is ensured. It is difficult to do so, and therefore the degree of freedom in layout of the auxiliary machine is necessarily limited.

On the other hand, in a so-called vertical engine, as disclosed in Japanese Utility Model Laid-Open No. 63-159322, the accessories are arranged in front of the engine and are connected by a propeller shaft. If so, it is possible to improve the degree of freedom in the layout of the auxiliary equipment by the distributed arrangement, but it is usually not easy to secure such a long space in the engine drive axis direction. Especially in so-called horizontal engines.

The present invention has been made in view of the above circumstances, and provides an auxiliary machine connecting structure capable of increasing the degree of freedom of auxiliary machine layout in an automobile in which an engine and a power transmission device are arranged in series. It is intended to be provided.

[0007]

According to the present invention, in general, an engine, including its intake and exhaust system members, has a larger cross-sectional area perpendicular to the drive shaft than a power transmission device. Therefore, the engine is arranged in series with the engine. In view of the fact that a dead space is likely to occur in the vicinity of the side portion of the power transmission device, the above-mentioned object is achieved by adopting the auxiliary equipment arrangement structure using this dead space.

That is, according to the present invention, as described in claim 1, in an automobile in which an engine and a power transmission device for transmitting a driving force of the engine are arranged in series, the engine and an auxiliary device driven by the engine And a structure in which the auxiliary machine is provided in the vicinity of a side portion of the power transmission device, and a drive shaft of the auxiliary machine is provided so as to extend in parallel with a drive shaft of the engine. It is characterized in that it is connected to an auxiliary machine driving output end on the side opposite to the power transmission machine side output end of the engine drive shaft via an auxiliary machine transmission shaft.

The above "power transmission device" is not particularly limited as long as it is a device for transmitting the driving force of the engine, and for example, only a clutch, an assembly of a clutch and a transmission or the like can be adopted, and The "clutch" conceptually includes a fluid clutch, a torque converter, and the like.

The "side portion" of the power transmission device means an end portion of the power transmission device in the direction orthogonal to the drive axis.

[0011]

As described above, in the present invention, the accessory is provided near the side of the power transmission device, and the drive shaft of the accessory extends parallel to the engine drive shaft. Since it is connected to the auxiliary drive output end on the side opposite to the power transmission device side output end of the engine drive shaft via the auxiliary transmission shaft, It is possible to realize the auxiliary machine connecting structure with a high degree of freedom in layout by effectively utilizing the dead space generated in the above, and to secure the auxiliary machine drive in that case.

Therefore, according to the present invention, in an automobile in which an engine and a power transmission device are arranged in series, it is possible to secure the drive of the auxiliary machine and increase the flexibility of the auxiliary machine layout.

Particularly, as described in claim 2, the engine and the power transmission device are arranged between a pair of side frames extending in the front-rear direction of the vehicle body on both sides of the vehicle body. When the direction of serial arrangement of the devices is set in the vehicle width direction, it is not possible to secure a long space in the engine drive axis direction, and therefore it is particularly effective to adopt the configuration of the present invention.

In the above structure, as described in claim 3, the surge tank of the engine is provided in the vicinity of the accessory transmission shaft, and the surge tank is provided with the shaft support portion for supporting the accessory transmission shaft. Therefore, it is possible to eliminate the need to newly provide a member for supporting the accessory transmission shaft.

In this case, as described in claim 4, a connection part of the surge tank with the intake system member of the engine is provided so as to extend parallel to the engine drive shaft, and an idler pulley can be rotated at this connection part. If the idler pulley is used for winding the accessory drive belt, it is possible to eliminate the need to newly provide a member for supporting the idler pulley.

Further, as described in claim 5, the surge tank is provided above the engine, the intake port of the engine is provided at a side portion of the engine, and the auxiliary machine transmission shaft is provided in the intake system member as the surge tank and the surge tank. If it is provided between the engine and the intake manifold portion that forms between the intake ports, it is possible to provide an auxiliary machine transmission shaft arrangement structure that effectively uses the dead space.

Further, as described in claim 6, when the engine is a dry sump type engine, a catch tank for supplying engine oil is provided, and this catch tank also has a intake tank portion and an engine. If it is provided between them, it is possible to further effectively use the dead space, and it is also possible to improve the safety at the time of a vehicle collision (engine oil outflow prevention).

When the engine is a dry sump type engine having a slant arrangement as described in claim 7, the accessory transmission shaft is provided in a space formed near the lower portion of the engine by the slant arrangement. With this, it is possible to provide an auxiliary machine transmission shaft disposition structure that effectively uses the dead space.

As described in claim 8, when the power transmission device is a clutch, the intake port and the exhaust port of the engine are provided on the same side of the engine, and the intake pipe connected to the intake port. The exhaust pipe connected to the exhaust port and the exhaust port are provided so as to form a space below the intake pipe and above the exhaust pipe, and the transmission is provided in this space. It is possible to suppress heat damage from the intake pipe to the intake pipe.
