Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a structure of an oil pan provided below an automobile engine.

(Prior Art) When the drive system of an automobile is FF and the engine is placed horizontally,
Since the exhaust manifold is installed on the front side of the car body because it needs to be cooled by the running wind, the exhaust pipe is installed close to the underside of the oil pan under the engine while it is extended to the rear part of the car body. Has been.

Further, in the above-mentioned type, there is a problem that the oil in the oil pan is thermally deteriorated due to the heat radiation from the exhaust pipe, so that a shielding member is usually provided between the oil pan and the exhaust pipe.

On the other hand, there has been a problem in that the so-called power plant vibrations cause noise in the vehicle interior when the connecting portions in the longitudinal direction of the respective constituent parts of the automobile such as the engine tend to move away during operation, which is a vibration source.

In order to solve this problem, it is known to reduce the power plant vibration by increasing the coupling force of the connection part of each component of the engine. (For example, the actual exploitation Sho 59-681
However, even in the case of the above, there is a problem that if the number of auxiliary machines serving as a vibration source is increased, the effect of reducing vibration cannot be sufficiently achieved.

(Purpose of the Invention) The present invention has been made in view of the above problems, and the purpose thereof is to utilize an existing shielding member provided between the oil pan and the exhaust pipe. It is to reduce power plant vibrations more effectively without increasing costs.

(Constitution of the Invention) The present invention for achieving the above object is an engine oil pan provided with an exhaust pipe adjacent to an oil pan located under a cylinder block connected to one end of an engine clutch housing. In the structure, a shielding member is provided between the oil pan and the exhaust pipe, and an upper surface and one end surface of the shielding member are fixed to a lower surface of the cylinder block and an end surface of the clutch housing, respectively. It is a structure.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

The engine is installed horizontally in the engine room of an FF type automobile, an oil pan (2) made of cast aluminum is provided at the lower end of the cylinder block (1) of the engine, and the exhaust pipe (3) is further provided with an engine. Of the exhaust manifold provided on the front side of the oil pan (2), and is bent and passes through a recess (2a) formed in the oil pan (2) to extend toward the rear of the vehicle body.

That is, the exhaust pipe (3) is provided close to the oil pan (2).

Reference numeral (4) is a shield member made of an iron plate, which is formed along the recessed portion (2a) of the oil pan (2) as shown in FIG. 3, and has flanges (6), (7) on its upper surface and one end. ) Is provided.

(5) is a clutch housing, one end of which is connected to the end surface of the cylinder block (1).

In the shielding member (4), the flange (6) on the upper surface is fixed to the lower surface of the cylinder block (1) and the flange (7) at one end is fixed to the end surface of the clutch housing (5) by bolts as shown in FIG. To be done.

In FIG. 1, the clutch housing (5) is shown by a chain double-dashed line, and the reference numeral (8) is a side frame.

With the above configuration, the shielding member (4) is attached so as to straddle the cylinder block (1) and the clutch housing (5), so that the connection between the cylinder block (1) and the clutch housing (5) is reinforced. As a result, power plant vibration can be significantly reduced.

In the illustrated state, the shielding member (4) is attached to the oil pan (2) in a joined state, but if the oil pan (2) is damaged, the engine oil drips onto the exhaust pipe (3). If it is possible to prevent the above, the shielding member (4) may be attached in a state of being separated from the oil pan (2).

(Advantages of the Invention) Since the present invention has the existing shielding member provided between the oil pan and the exhaust pipe fixed across the cylinder block and the clutch housing, the power can be increased without increasing the cost. Plant vibration can be effectively reduced.
