DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for disposing auxiliary equipment for a vehicle.

[0002]

2. Description of the Related Art Japanese Patent Laid-Open Publication No. 1-2
As shown in Japanese Patent No. 40323, it is generally known that a radiator as an auxiliary device is disposed at a predetermined interval in front of a vehicle body of an engine and a transmission arranged sideways.

[0003]

However, in the above-described arrangement structure, the radiators are arranged at a predetermined interval in front of the vehicle body such as an engine, so that the engine room is arranged in the longitudinal direction of the vehicle body. It has to be one of the causes of long extension. For this reason, when it is assumed that the entire length of the vehicle body is constant, it is difficult to increase the size of the cabin. The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a vehicle auxiliary machine arrangement structure that can reduce an engine room in a vehicle longitudinal direction as much as possible.

[0004]

In order to achieve the above object, according to the present invention (the invention according to claim 1), a transmission is provided at a side of an engine arranged horizontally, and an axial center of the transmission is provided. Is arranged in the same state with respect to the axis of the engine, a differential device is juxtaposed on the rear side of the vehicle body of the transmission, and a radiator is arranged on the front side of the vehicle body of the engine and the transmission. In the structure for disposing auxiliary equipment, the engine and the transmission and the differential are arranged such that a vertical distance between an axis of the engine and the transmission and an axis of the differential is equal to the distance between the two axes. The transmission is arranged in a step space formed by the engine and the transmission so as to be longer than the distance between the centers in the vehicle longitudinal direction. The radiator in the vehicle body front side is arranged, on the lower side of the engine and the transmission, it is constituted that an exhaust pipe extending from the engine is disposed. Preferred embodiments of the first aspect are as described in the second and third aspects.

[0005]

According to the first aspect of the present invention, the step space formed by the engine and the transmission is effectively used for disposing the radiator. Therefore, the engine room can be reduced as much as possible in the longitudinal direction of the vehicle body. Also, the engine and transmission and the differential may have a vertical distance between the axis of the engine and transmission and the axis of the differential longer than the longitudinal distance between the two axes. Since the engine, transmission, and differential are arranged side by side, the engine, transmission, and differential are arranged side by side in the vehicle longitudinal direction. It can be narrowed compared to the case of doing so. For this reason,
The engine room can be shortened in the vehicle longitudinal direction. In addition, the engine and transmission,
Based on the above-described arrangement with the differential, the step space formed by the engine and the transmission is expanded upward, and accordingly, the radiator can be expanded upward. Therefore, when the radiator is expanded upward as described above, the cooling performance of the engine cooling water can be improved. Furthermore, with the engine and transmission,
Based on the above-described arrangement relationship with the differential device, a new space is formed below the engine and the transmission and on the vehicle body front side of the engine and the transmission, and the new space is formed. It can be effectively used as a space for disposing an exhaust pipe extending from the engine. According to the second aspect of the present invention, since the intake system of the engine is provided outside the vehicle body rear side region of the radiator, in addition to producing the same operation and effect as in the first aspect, the intake system is also provided. Since the air does not reach the air flow area that has passed through the radiator, it is possible to prevent the intake air from being heated. For this reason, the charging efficiency of the intake air can be improved. According to the third aspect of the invention, the same operation and effect as those of the second aspect can be obtained with a specific configuration.

The compressor 20 is mounted on an oil pan (oil pan rail) 19 via a bracket 21 as shown in FIGS. 7 and 8, and the compressor 20 is positioned so as to enter the new space 18. I have.

As shown in FIG. 3, FIG. 4, FIG. 6, and FIG.
2 is extended, and a bank 11 on the rear side of the body of the engine 7 is provided.
An exhaust pipe 23 extends from the opening. The exhaust pipe 22 extends downward from the bank 10, while the exhaust pipe 23 wraps around the engine 7 above the transmission 9 and is connected to the exhaust pipe 22. It is summarized. The common exhaust pipe 24 extends under the power plant 6 and extends rearward of the vehicle body. The common exhaust pipe 24 passes through the new space 18 on the way. A pre-catalyst 25 is interposed in each of the exhaust pipes 22 and 23, and a main catalyst 26, a flexible pipe 27, a main silencer 28, and the like are sequentially provided in the common exhaust pipe 24 from the upstream side to the downstream side. Is interposed. Of these, the main catalyst 26
As shown in FIGS. 4 and 7, the main catalyst 26 is attached to the lower part of the power plant 6 (transmission 9) via a metal bracket 29.
The new space 1 is located below the power plant 6 (below the vicinity of the junction between the engine 7 and the transmission 9).
8.

As shown in FIGS. 1 to 3 and FIG. 6, a radiator 30 is provided in the step space 12 at the front side of the vehicle body of the transmission 9. Radiator 3

As a result, the vehicle compartment can be expanded on the assumption that the entire length of the vehicle body is constant.

Further, by providing the above-described arrangement relationship between the differential device 16 and the power plant 6, the power plant 6 is moved from the previous position (conventional position), and as a result, the power plant occupied as it is. -A part of the unit installation space becomes a new space 18, and the new space 18 can be used as an installation space for engine room installation parts. For this reason, the compressor 20 disposed in the new space,
With respect to the common exhaust pipe 24 and the main catalyst 26, the degree of freedom of arrangement can be increased.

Furthermore, not only is the main catalyst 26 disposed near the power plant 6, but also because the main catalyst 26 is attached to the power plant 6 via the metal bracket 29, Is transferred to the main catalyst 26 through convection, conduction, and the like, and the main catalyst 26 can work effectively.

Further, when the radiator 30 is disposed, the radiator 30 is disposed in the step space 12 on the vehicle body front side of the transmission 9 so that the step space 12
, The engine room 4 can be shortened in the vehicle longitudinal direction. In this case, the power plant 6 is lifted and the step space 12 is raised.
Is expanded upward, so that the radiator 3
0 can be expanded upward. For this reason, when the radiator 30 is expanded upward, the cooling performance of the engine cooling water can be improved.

In addition, an intake system such as a surge tank 35, a downstream intake pipe group 36, an upstream intake pipe 37, an air cleaner 38, and an intake pipe 39 is disposed outside the radiator 30 outside the vehicle body rear area. Because it is installed, the intake system
Therefore, it is possible to prevent the air from being heated by the air passing through the air, thereby improving the charging efficiency of the intake air.
