BACKGROUND OF THE INVENTION
The present invention relates to a fuel filter mounting structure, and more particularly to a fuel filter mounting structure provided in a fuel supply pipe in an engine room.
[0002]
[Prior art]
In recent years, FF (Front engine Front drive) type drive systems have become mainstream in automobiles. In such FF type vehicles, the engine is directed toward the vehicle body width direction in the engine room (that is, the vehicle body). It is mounted by mounting horizontally (substantially perpendicular to the front-rear direction).
[0003]
The engine is supplied with fuel from a fuel tank via a fuel supply pipe. The fuel supply pipe is provided with a fuel filter for filtering impurities such as dust contained in the fuel supplied from the fuel tank to the engine.
[0004]
For example, in Patent Document 1, a fuel filter is provided on the front surface of the dash panel that is provided in the vertical direction of the vehicle body and that is on the vehicle body front side of the dash panel that partitions the engine room and the vehicle compartment. There is disclosed a fuel filter mounting structure that is disposed through a bracket while being covered with a protector.

It is a principal part enlarged view which shows a mode that the attachment structure of a filter changes when a load is added. 1 and 3, the lower side of the drawing indicates the front side of the vehicle body.
[0015]
In FIG. 1, reference numeral 10 denotes an entire engine room. Between a pair of front side members 11, 11 extending in the vehicle body front-rear direction on both sides in the vehicle body width direction, an engine 12 and the engine 12 are provided side by side. A transmission 13 that transmits the driving force is mounted by mounting portions 14a and 14b provided on the left and right in the vehicle body width direction.
[0016]
In the engine room 10, a fuel supply pipe (not shown) for supplying fuel from a fuel tank (not shown) to the engine 12 is disposed, and the fuel tank is fed from the fuel tank to the engine 12. A fuel filter 15 is provided for filtering impurities such as dust contained in the fuel.
[0017]
The fuel filter 15 is a bracket 16 as a fixing means having a strength weaker than the strength of the fuel filter 15 on the vehicle body rear side of the transmission 13 in one of the pair of front side members 11, 11. It is arranged via.
[0018]
In the case of the present embodiment, a protector 17 is provided on the periphery of the fuel filter 15 as a protection means that is stronger than the bracket 16 so as to surround the periphery. The protector 17 is a bracket. 16 is attached using a technique such as welding.
[0019]
Further, an air cleaner 20 is disposed near the dash panel 19 provided on the vehicle body rear side and in the vehicle body vertical direction with respect to the strut housing 18 provided on both sides in the vehicle body width direction in the engine room 10. A battery 21 is disposed on the front side of the vehicle body.
[0020]
In the present embodiment, an air cleaner 20 is disposed in the vicinity of the dash panel 19 and a battery 21 is disposed on the front side of the vehicle body from the air cleaner 20. The arrangement of the air cleaner 20 and the battery 21 is reversed, that is, the battery 21 is arranged in the vicinity of the dash panel 19, and the air cleaner 20 is arranged in front of the vehicle body from the battery 21. Needless to say, it is good.
[0021]
Thus, in this fuel filter 15 mounting structure, the fuel filter 15 is disposed on the vehicle body rear side of the transmission 13 of the front side member 11, and the air cleaner 20 is disposed on the vehicle body rear side of the strut housing 18 and in the vicinity of the dash panel 19. In addition, since the battery 21 is disposed on the front side of the vehicle body relative to the air cleaner 20, it is possible to increase the degree of freedom of modeling the headlamp (not shown) and reduce the front overhang of the vehicle body.
[0022]
Specifically, as shown in FIG. 2, the fuel filter 15 is disposed above the steering rack 22 by a bracket 16. At this time, the bracket 16 is a component mounted in another engine room 10, for example, A bolt 24 or the like is attached to the front side member 11 toward the side of the vehicle body so as to be positioned above the stabilizer 23 or the like.

[0024]
Since the engine 12 and the transmission 13 move rearward around the mount portion 14a opposite to the broken mount portion 14b, the fuel filter 15 disposed at the rear of the vehicle body of the transmission 13 includes the load F ₂ applied in the direction indicated by the arrow.
[0025]
At this time, since the fuel filter 15 is covered with the protector 17 as described above, direct interference between the fuel filter 15 and the transmission 13 moving backward can be prevented.
[0026]
Then, energy caused by the load F ₂ is transmitted to the bracket 16 through the protector 17, as shown in FIG. 4 that the same reference numerals are added to corresponding parts in FIG. 2, this by being absorbed into the bracket 16 In order to deform the bracket 16, a bent portion 16 a is formed in the bracket 16.
[0027]
More specifically, as shown in FIGS. 5A to 5C, when a load F ₂ is applied to the protector 17 surrounding the fuel filter 15, the protector 17 has a lower portion 17 a below the bracket 16. After coming into contact with the placed stabilizer 23, the lower portion 17a is used as an axis to be pressed in the vehicle body width direction.
[0028]
As a result, the bracket 16 is deformed into a V-shape on the paper surface of FIG. 5 and translates the fuel filter 15 in the vehicle body width direction, so that the fuel filter 15 is damaged by interference with the transmission 13 that has moved backward. Can be prevented beforehand.
[0029]
Incidentally, a drain 25 for draining water is usually provided in the lower part of the fuel filter 15, and this drain 25 is covered with a protector 17 from the maintainability of opening the drain 25 and draining water at the time of inspection or the like. However, when the engine 12 and the transmission 13 are moved rearward, the drain 25 interferes with the steering rack 22 located below the fuel filter 15 and the fuel filter 15 is damaged. There is also.
[0030]
However, in the present invention, the lower portion 17a of the protector 17 is in contact with the stabilizer 23, thereby avoiding interference between the drain 25 provided below the fuel filter 15 and the steering rack 22 positioned below the fuel filter 15. Therefore, the fuel filter 15 can be prevented from being damaged.
[0031]
As described above, according to the mounting structure of the fuel filter 15, the fuel filter 15 is disposed on the rear side of the vehicle body from the transmission 13 in one of the pair of front side members 11, and the vehicle body from the strut housing 18. By arranging the air cleaner 20 on the rear side and in the vicinity of the dash panel 19, and further arranging the battery 21 on the front side of the vehicle body from the air cleaner 20, the degree of freedom of modeling of the headlamp and the front overhang of the vehicle body are reduced. Reduction can be enabled.
[0032]
At the same time, according to the mounting structure of the fuel filter 15, the fuel filter 15 is mounted by the bracket 16 having a weaker strength than that of the fuel filter 15. _Even when the engine 12 or the transmission 13 moves backward with the addition of ₁ , the bracket 16 is deformed before the fuel filter 15, and the position of the fuel filter 15 is moved in the vehicle body side direction. Therefore, the fuel filter 15 can be prevented from being damaged.
[0033]
In addition, since the bracket 16 is disposed at a position where the stabilizer 23 as a component mounted in the other engine room 10 is disposed below the bracket 16, the lower portion 17 a of the protector 17 is connected to the stabilizer 23. By contacting, it is possible to avoid interference between the drain 25 provided below the fuel filter 15 and the steering rack 22 positioned below the fuel filter 15, thereby preventing the fuel filter 15 from being damaged in advance. Can do.
[0034]
Further, according to the mounting structure of the fuel filter 15, the fuel filter 15 is protected by the protector 17 having a strength stronger than that of the bracket 16, so that the direct connection between the fuel filter 15 and the transmission 13 moving backward is possible. An advantage that interference can be prevented can also be obtained.
