Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a support structure for an air cleaner of an engine mounted horizontally.

[Prior Art] Front engine As in a front-drive vehicle, in a horizontally mounted engine with the front-rear direction of the engine oriented in the width direction of the vehicle, conventionally, the nose of the air cleaner is passed above the engine.

However, in such a conventional structure, although the size of the entire engine in the vehicle width direction can be suppressed to be relatively small,
The height of the engine is increased by moving the air cleaners upwards, making it difficult to adapt to recent vehicles where low vehicle height and low bonnet are desired.
Further, when the air cleaners are passed over the engine, the air cleaners are directly exposed to the high temperature rising airflow from the engine body, so that there is a problem that the temperature of the intake air may rise excessively.

[Problems to be Solved by the Invention] The present invention focuses on the above-mentioned problems, removes the air cleaner nanoses from above the engine and properly supports the air cleaner nanoises, suppresses the overall height of the engine, and reduces the intake air temperature. The purpose is to prevent the excessive rise of.

Further, in supporting the air cleaners, it is also an object to prevent the air cleaners from being easily disengaged by vibration or the like, and to easily block the vibrations from the engine body side.

In addition, as a conventional technique related to the present invention,
No. 216 and No. 60-51314, a fixing structure using a clip nut, and No. 57-142146, a cover supporting structure with an elastic body are disclosed. The arrangement and its supporting structure are not disclosed.

[Means for Solving Problems] The support structure of the air cleaner of the present invention, which meets the above-mentioned object, has a nose of an air cleaner in a laterally mounted engine with the front-rear direction of the engine oriented in the width direction of the vehicle. It is extended to the side, and consists of an air cleaner that is supported by a timing belt cover.

This support is performed, for example, by providing an air cleaner nanoise support portion integrally formed with the timing belt cover on the side surface of the timing belt cover and supporting the air cleaner nanoises on the air cleaner nanoise support portion.

In addition, it is desirable that the air cleaners are supported on the air cleaner supporter via an elastic body. Further, a U-shaped groove opening toward the rear side of the engine is formed in the air cleaner nano-bearing portion, a clip nut is inserted into the air cleaner nano-bearing portion from the front side of the engine, and the clip nut is inserted into the air cleaner nano-bearing portion and screwed into the clip nut. The air cleaners may be supported by the air cleaner supporter via the corresponding bolts.

[Operation] In such an air cleaner support structure,
Since the air cleaner is extended to the front side of the timing belt cover, the air cleaner is not directly related to the total height of the engine, and the total height of the engine is substantially the height of the engine itself. Therefore, the overall height of the engine can be kept low as compared with the conventional case where air cleaners are provided above the engine. Further, since the high temperature rising airflow from the engine does not come to the front side of the timing belt cover, the intake air temperature is surely prevented from rising excessively. The air cleaners are supported by the timing belt cover. Since the timing belt cover is a mounting component that is formed separately from the cylinder block and the cylinder head of the engine body, the supporting portion for the air cleaner is easily provided.

Also, if the air cleaner support is provided on the side of the timing belt cover and near the bolt hole for mounting the timing belt cover, the air cleaner is supported near the part firmly fixed to the engine body by the mounting bolt. Therefore, the supporting strength is sufficiently secured. Further, if the air cleaners are supported via the elastic body, vibrations can be appropriately blocked between the engine cleaner and the engine body, and loosening and the like can be prevented. Further, a U-shaped groove opening toward the rear side of the engine is formed in the air cleaner chain support portion provided on the side surface of the timing belt cover, a clip nut is inserted from the front side of the engine, and the clip nut is inserted into the air cleaner chain support portion. If the air cleaner is supported by a screwing bolt such as a stud bolt, the stud bolt is disengaged toward the front side of the engine at the portion where vibration in the engine front-rear direction mainly occurs. It is regulated by the bottom of the groove, and it is prevented from coming off to the rear side of the engine by the clip nut or by hitting the timing belt cover with the air cleaner nanoses themselves, so that the bolts can be efficiently removed with a simple structure, and therefore the removal of the air cleaner nanoes can be prevented. Is prevented , Ensuring of the support is achieved.

[Embodiment] Hereinafter, a preferred embodiment of the present invention will be described with reference to the drawings.

1 to 6 show an air cleaner nanoz support structure according to an embodiment of the present invention. In the figure, 1
Shows an engine main body mounted laterally with the front-rear direction of the engine facing the width direction of the vehicle, and 2 shows an air cleaner. The air cleaner 2 is provided with an air cleaner 3 for guiding intake air to the main body of the air cleaner 2, and the air cleaner 3 is extended to the front side of the timing belt cover 4. Therefore, the air cleaners 3 are not passed over the engine body 1.

In the middle of the air cleaner, the hot air pipe (hot air hose) 6 connected to the exhaust manifold 5 is connected, and the exhaust manifold 5 is connected.
The hot air warmed by is introduced appropriately. Also, in the middle of Air Cleaners 3,
A bellows pipe 7 is interposed so that vibration transmission can be appropriately blocked at this portion.

The air cleaner'nose 3 extended to the front side of the timing belt cover 4 is provided on the side surface 4a of the timing belt cover 4, and is supported by the air cleaner's support 8 formed integrally with the timing belt cover 4 made of resin. It As shown in FIGS. 3 to 5, the air cleaner support 8 is provided on the side surface 4a of the timing belt cover 4 and in the vicinity of the mounting boss 10 having the mounting bolt holes 9 for the timing belt cover 4. Has been. The upper surface 8a of the air cleaner's support portion 8 is formed as a flat seat surface.

A U-shaped groove 11 that opens toward the rear side of the engine is formed in the air cleaner support 8, and the inside of the U-shaped groove 11 near the bottom 12 of the groove 11 is formed in a through hole 13. There is. A clip nut 14 is inserted into this air cleaner support 8 from the front side of the engine. The clip nut 14 is composed of a plate-shaped body 14a having a generally U-shaped elasticity, and has a nut portion 14b on the lower surface side thereof.
The elasticity of the air cleaner pinches the supporting portion 8 between them. A stud bolt 18 is screwed into the nut portion 14b of the clip nut 14 as shown in FIG. Then, the stay 17 fixed to the air cleaners 3 is fixed by tightening the nut 18a through the collar 15 and the elastic bodies 16a and 16b as cushioning materials, whereby the stay 17, the elastic bodies 16a and 16b, the collar 15, The air cleaner nanoses 3 are fixedly supported by the air cleaner nanoise support portion 8 via the clip nuts 14.

In the device configured as described above, since the air cleaner nanose 3 is extended to the front side of the timing belt cover 4, as is apparent from FIG. The engine height can be kept low compared to when the engine is passed over. Further, since the high-temperature ascending airflow from the engine body 1 does not directly hit the air cleaner nanoses 3, the air cleaner nanoises 3 are prevented from being heated to a high temperature, and the excessive rise of the intake air temperature is surely prevented.

Further, since the air cleaner nano 3 is supported by the timing belt cover 4 and the supporting portion 8 is provided in the vicinity of the mounting boss portion 10 that is firmly fixed to the engine body 1 side, the support strength of the air cleaner nano 3 itself is sufficient. Secured. Further, the U-shaped groove 11 is formed so as to open toward the engine rear side, the clip nut 14 is inserted from the engine front side, the stud bolt 18 is inserted into the through hole 13, and the clip nut 14 is screwed into the clip nut 14. To be done. In this part of the structure, the support of the air cleaner is ensured unless the stud bolt 18 is removed. In this portion, vibration is likely to occur mainly in the engine front-rear direction (XX direction in FIGS. 5 and 6), but the movement of the stud bolt 18 toward the front side of the engine is caused by the bottom of the U-shaped groove 11.
Since it is regulated by 12, the disengagement in this direction is surely prevented, and the movement toward the engine rear side is regulated by the clip nut 14 or by the air cleaner nano 3 itself hitting the timing belt cover 4. Therefore, the stud bolt in the front-back direction of the engine
18 disengagement (removal) is prevented, and air cleaner Nano's 3
The stable support state of is secured.

The groove or hole provided in the air cleaner support 8 may have the shape shown in FIGS. 7 to 9, for example. FIG. 7 shows a U-shaped groove 19 which is open toward the front side of the engine.
The figure shows only the one provided with the through hole 20, and FIG. 9 shows the one provided with the U-shaped groove 21 opened in the lateral direction.
However, in the structure shown in FIG. 7, the above-described groove bottom portion 12 does not provide the detachment preventing action, and in the structures shown in FIGS. 8 and 9, the portions where holes and grooves are formed at the time of molding the timing belt cover are not formed. Since it is necessary to pull the mold upward or sideways, the structure of the mold may be complicated and the molding process may be complicated. That is, the timing belt cover 4 can be easily formed by simply pulling out the molding die to the front side and the rear side of the engine, as shown by the mold dividing parting line 22 at the time of molding in FIG. By adopting the direction of the U-shaped groove 11 as shown in the embodiment, the ease of molding can be ensured as it is. Therefore, it is best to make the U-shaped groove 11 open toward the rear side of the engine.

Further, since the air cleaner nanoses 3 are supported via the elastic bodies 16a and 16b, vibration transmission between the air cleaner nanoises 3 and the engine body 1 side is appropriately blocked, and the air cleaner nanoises 3 are appropriately protected. The looseness of the supporting part is also prevented. Further, in this embodiment, the bellows tube 7
The vibration transmission can be further suppressed because the is installed.

[Effect of the Invention] As described above, in the air cleaner support structure of the present invention, since the air cleaner nanos is extended to the front side of the timing belt cover and supported by the timing belt cover, the overall height of the horizontal engine is reduced. Can be kept low, and an excessive rise in intake air temperature can be prevented.

Further, by supporting the air cleaner nanoses through the elastic body, the loosening of the supporting portion is prevented, the air cleaner nanoses themselves are appropriately protected, and the durability thereof is improved.

Furthermore, if the air cleaner chain support section has a combined structure of a U-shaped groove that opens toward the rear side of the engine and a clip nut that is inserted from the front side of the engine, loosening and disengagement of the air cleaner chain support section will be more reliable. It is prevented and a stable support state is secured.
