Description

[Detailed explanation of the idea] The present invention relates to a fuel tank mounting device for a motorcycle.

In order to make the installation work of the fuel tank easier than in the past, for example, referring to FIG. A mounting device has been developed that allows the tightening work to be performed at an easily accessible location.

However, in the conventional mounting device, as shown in FIG. 3, for example, the left and right end portions of the second bracket 13' are integrally welded to the left and right frame vibrators, which causes the following problems.

In other words, the second bracket 13' gets in the way, and the battery 33 and air cleaner 3 are placed under the second bracket 13'.
4 was difficult to install and to inspect and repair after installation.

Moreover, in order to enable inspection and repair of the air cleaner 34, etc., the height H of the second bracket 13' is made higher than necessary over almost the entire left and right width, so that the upper surface of the air cleaner 34, etc. and the second bracket 13 are made higher than necessary. It was necessary to ensure that the space between ′ was wide enough to allow at least a hand to be inserted.

However, if the height H of the second bracket 13' is increased, the thickness of the cushioning material of the front seat must be made thinner, resulting in a problem of poor riding comfort.

The present invention is intended to solve the above-mentioned problems, and its purpose is to (1) facilitate the assembly of the tank to the vehicle body; (2)
The installation of the battery, air cleaner, etc. placed under the front seat facilitates inspection and repair work, and (3) improves the cushioning properties of the front seat by ensuring sufficient space for the front seat. First, the present invention will be explained based on the drawings.

In Fig. 1a, which is a partial side view of a two-wheeled motor vehicle, 1 is a head pipe at the front end of the frame, 2 is a front frame pipe extending rearward from the head pipe 1 in a slightly curved shape, and 3 is a part extending from the head pipe 1 toward the rear and downward. This is a lower frame pipe that extends, and from a portion of the front frame pipe 2 near the rear end of the fuel tank 5, a pair of left and right substantially horizontal frame vibrators extend rearward.

A support shaft 7 extending left and right is formed on the rear side of the upper end of the lower frame pipe 3, and a pair of left and right bottomed cylindrical rubber dampers 8 are fitted on the outer periphery of the support shaft 7.

The fuel tank 5 is formed into a left and right bifurcated shape so that it can straddle the front frame vibe 2 from above. A front-opening U-shaped bracket 10 is formed on each of the two, and the U-shaped bracket 10 is fitted onto the rubber damper 8 from the outside.

A flat plate-shaped first bracket 12 extending rearward is welded to the center portion of the left and right width of the rear end of the tank 5, for example, to the rear end of the tank bottom plate 11 facing the front frame pipe 2 from above. The rear end of the first bracket 1 is connected to the first bracket 1.
2. The first bracket 12 is attached to the frame vibro via a mounting device comprising a second bracket 13 that supports the first bracket 12 from below and support brackets 14 provided on a pair of left and right frame vibros.

That is, in FIG. 1b, which is an enlarged partial cross-sectional view of the arrow A portion in FIG. 1, a support bracket 14 is formed (welded) on the upper side of the left and right frame vibros and extends rearward along the frame vibros. The support bracket 14 has a U-shaped cross section (FIG. 2), and one first nut portion 16 on the left and right sides for attaching the second bracket is provided on the lower surface of the earthen wall at the front end of the support bracket 14. In the latter half of the support bracket 14, two second nut portions 17 are provided on each of the left and right sides for attaching the battery case.

In FIG. 2, which is a cross-sectional rear view taken along line II-II in FIG. By screwing into the portion 16, the second bracket 13 can be detachably attached to the support bracket 14.

A planar seat 20 projecting upward is formed at the center of the left-right width of the second bracket 13, and a third nut portion 21 is formed (welded) on the lower surface of the seat 20.

A bolt insertion hole 24 is formed in the first bracket 12, and a cylindrical damper rubber 2 is inserted into the bolt insertion hole 24.
3 is fitted into the damper rubber 23, and a collar 22 having a brim at the upper end is fitted into the inner peripheral side of the damper rubber 23.

That is, the first bracket 12 is fixed to the seat 20 by screwing the tank mounting bolt 25 inserted into the collar 22 from above into the third nut part 21.

Note that an annular groove is formed on the outer peripheral surface of the damper rubber 23, and the engagement between the annular groove and the first bracket 12 allows
The damper rubber 23 is removed from the first bracket 12 to prevent it from falling.

A pair of left and right front seat stoppers 26 are integrally formed (welded) with the second bracket 13 on both the left and right sides of the catch seat 20, and these stoppers 26 are connected to the second seat stoppers 26 as shown in FIG. 1b.
It extends rearward from the bracket 13, and is bent so that a portion on the rear side of the rear end edge of the second bracket 13 is slightly higher than the second bracket 13.

That is, by inserting the forward-protruding retaining piece 28 formed at the lower end of the front seat 27 into the lower side of the stopper 26 from behind, the upward movement of the front end of the front seat 27 is restricted. ing.

30 is a damper arranged between the lower surface of the front seat 27 and the frame vibro.

A second nut portion 17 is attached to the rear half of the support bracket 14.
A battery case 35 is attached by a bolt 31 (FIG. 1b) that is screwed into the battery case 35.

Also, an air cleaner 34 (
Figure 1a).

According to the present invention having the above configuration: (1) Since the second bracket 13 is detachable from the support brackets 14 of the left and right frame vibros, by removing the second bracket 13 from the support bracket 14, the air cleaner 34 and battery can be removed. 33 on the front lower side of the front seat 27 or battery 33
This makes it easier to inspect and repair items such as equipment.

To explain in more detail, as shown in FIG. 2, a pair of left and right support brackets 14 are provided, both support brackets 14 are formed independently on the left and right frame vibros, and the second bracket 13 spanning between both the vibros is formed as described above. It is detachably attached to both support brackets 14.

That is, since the second bracket 13 covering the upper side of the air cleaner 33 etc. between both frame vibrators is detachable,
By removing the second bracket 13 from the support bracket 14, there is no longer a member covering the top between both vibrators.
As a result, the air cleaner 33 is placed between both vibros.
Also, inspection and repair work on the battery 34 becomes easier.

(2) Since the second bracket 13 is detachable from the support brackets 14 of the left and right frame vibros, it is not necessary to secure a large space between the second bracket 13 and the upper surface of the air cleaner 34, etc. This means that inspection and repair work can be carried out by moving the second bracket 13 as close to the top surface of the air cleaner 34 as possible.
The height of the bracket 13 can be kept low.

Therefore, the thickness of the cushioning material of the front seat 27 can be ensured sufficiently, and a comfortable ride can be ensured.

(3) Since the first bracket 12 and the second bracket 13 are arranged at a position behind the fuel tank 5, that is, at a position where they can be easily seen and easily reached, the work of attaching the fuel tank 5 can be easily performed.

(4) Since the battery case support part is integrally formed at the rear of the support bracket 14 and the support bracket 14 is used for fixing the battery case, the number of parts is reduced, which facilitates installation work and parts management. .

Furthermore, the strength of the support bracket 14 is also increased.

Furthermore, if the front seat stopper 26 is integrally fixed to the second bracket 13 and the second bracket 13 is used to fix the front seat 27, the number of parts required to attach the fuel tank 5, front seat 27, and battery case 35 can be greatly reduced. This makes the mounting structure simpler and the cost lower.

In FIG. 3, the same parts as those shown in FIG. 2 are given the same numbers as in FIG.
