BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for disposing a cooling water pipe for a vehicle, which can be applied to a vehicle equipped with a water-cooled engine.

[0002]

2. Description of the Related Art In a vehicle such as an automobile, a transmission is connected to a cylinder block of an engine.
It is common to make these into an integrated structure (J.
-29639, JP-A-63-73524, etc.). Then, a stiffener is used as a member for making the connection harder. By the way, in a vehicle in which an engine is disposed at a front portion of a vehicle body, a structure in which a part of a cooling water pipe of the engine passes through a lower portion of a transmission is often used.

This will be described with reference to FIG. 1 is an engine, 2 is a cylinder head, 3 is a cylinder block, and 4 is an oil pan. An exhaust manifold 5 is attached to the cylinder block 3, and an exhaust pipe 6 is connected to an end of the exhaust manifold 5. A transmission 7 is firmly connected to the cylinder block 3 by bolts (not shown). A cooling water pipe 8 through which engine cooling water passes is supported by a retainer 9 at a position below the transmission 7 near the exhaust pipe 6.

[0004]

When the cooling water pipe 8 is disposed in such a position, the cooling water pipe naturally projects downward from the transmission 7 and is therefore close to the road surface, so that it is close to the front wheel. There is a possibility that the pebbles and the like hit by the ball may be damaged by hitting. To prevent this, a cover is mounted. However, a large space is required in layout, and the mounting structure of the cover is complicated, which increases the weight and increases the cost.

The present invention has been made in view of this point, has a simpler structure than the conventional one, and has a cooling water pipe which is not affected by stepping stones or the like and has a heat shielding effect from an exhaust pipe. It is an object of the present invention to provide a structure for disposing a cooling pipe for a vehicle.

[0006]

According to the present invention, as a means for solving the above problems, the cylinder block side portion of the transmission connected to the cylinder block of the engine and the cylinder block are reinforced with a stiffener. A space is formed between the stiffener, the lower portion of the cylinder block, and the transmission, and a cooling water pipe for the engine is disposed in the space.

[0007]

With this configuration, the cooling water pipe is located in the space formed between the stiffener and the lower portion of the cylinder block and between the transmission and the vehicle, so that even if the front wheels scatter pebbles, etc., they do not hit. become.
Also, unlike the case where the transmission is supported at the lower part, the height from the road surface is increased, so that a protective cover or the like is not required.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 1 to 3 by attaching the same reference numerals to the same members as in FIG. Between the lower part of the cylinder block 3 of the engine 1 and the lower part (bottom part) of the transmission 7, a stiffener 10 having a shape obliquely descending from the cylinder block 3 side to the transmission 7 side as shown in the figure is arranged. It is attached to the cylinder block 3 by bolts 11 and to the transmission 7 by bolts 12. Thereby, the degree of coupling between the cylinder block 3 and the transmission 7 is reinforced.

[0009] The shape of the oil pan 4, as shown door
Lance Mission 7 deeply on the opposite side, by as transmission 7 side is shallow, the stiffener 1
0 is provided in the lower part of the stiffener 10 in the space 13.
And a space 14 above the stiffener 10. A part of the exhaust pipe 6 is provided in the space 13, and a part of the cooling water pipe 8 is provided in the space 14. As a result, the cooling water pipe 8 is located at a substantially triangular portion surrounded by the oil pan 4, the transmission 7, and the stiffener 10, and is substantially parallel to the exhaust pipe 6 located below the stiffener 10. In FIG.
5 is a radiator, 16 is a cross member of the vehicle body, and 17 is a radiator hose connecting the cooling water pipe 8 and the radiator 15.

The arrangement structure of the vehicle cooling water pipe configured as described above has a problem in that the stiffener 10 is located below the front part of the cooling water pipe 8 so that pebbles hit by the front wheels and obstacles on the road are caused. The stiffener 10 protects the cooling water pipe 8 against objects and the like. Therefore, a cover for protecting the cooling water pipe 8 is not required, and the freedom of layout and the weight can be reduced.

[0011]

[Effects of the Invention] The present invention has a vehicle cooling water pipe structure constructed as described above. Therefore, the layout of the stiffener and the cooling water pipe allows the cooling water pipe to be mounted without a cover or the like. The cooling water pipe can be protected from stepping stones and obstacles. In addition, the stiffener can provide a heat shielding effect from the exhaust pipe. By arranging the cooling water pipe in such a layout, the length of the cooling water pipe can be shortened compared to the conventional one that passes through the lower part of the transmission, so that the weight and cost are reduced. Can be done.
