本考案は自動二輪車に装備された負圧倍力装置
のバキユームタンクに関するものである。[Detailed Description of the Invention] The present invention relates to a vacuum tank for a negative pressure booster installed in a motorcycle.
負圧倍力装置の負圧室はバキユームホースを介
して負圧源である吸気マニホールドに連通させて
常に負圧に保つ必要がある。 The negative pressure chamber of the negative pressure booster must be communicated with the intake manifold, which is a negative pressure source, via a vacuum hose to maintain a negative pressure at all times.
しかるに自動二輪車は小排気量の原動機を使用
しているものが多く、負圧源の容量が小さいこ
と、又取付スペースや外観上の観点から比較的小
型であるため、負圧倍力室の負圧室の容積が小さ
いこと等により使用によつて低下した負圧の復帰
に時間を要することから、別途にバキユームタン
クを設けて負圧を常に確保する必要がある。 However, many motorcycles use motors with small displacement, so the capacity of the negative pressure source is small, and the negative pressure source is relatively small in terms of installation space and appearance. Because the volume of the pressure chamber is small, it takes time to restore the negative pressure that has fallen due to use, so it is necessary to provide a separate vacuum tank to always ensure negative pressure.
しかし、自動二輪車にバキユームタンクを車体
に取付けることは取付スペースの問題があり、又
車体重量の増加につながることになる。 However, attaching a vacuum tank to the body of a motorcycle poses a problem of installation space and also leads to an increase in the weight of the vehicle.
そこで本考案は上記の点に鑑みなされたもの

ことにある。 Therefore, the present invention was developed in view of the above points, and the pipes constituting the vehicle body frame are connected airtightly to form a plurality of independent chambers within the vehicle body frame, and each of these chambers is connected to a negative pressure source. The feature is that each chamber communicates with the negative pressure chamber of the negative pressure booster, and the purpose is to use the existing body frame as a vacuum tank and to increase the volume of the vacuum tank. It's because we made it bigger.
以下図示の一実施例について説明すると、車体
フレーム１は複数のパイプ１ａ，１ｂ，１ｃ等を

る。 To explain one embodiment shown below, the vehicle body frame 1 is constructed by airtightly welding a plurality of pipes 1a, 1b, 1c, etc.
The interior is made up of independent chambers 2a, 2b, and 2c.
車体フレーム１の前方にはフロントフオーク３

いる。 A negative pressure booster 6 is attached to the front fork 3, and a push rod arm 8 that pushes a push rod 7 of the device 6 is connected to a brake cable 10 whose one end is connected to the brake lever 9 of the handle 4. The output side of the negative pressure booster 6 is connected to the brake hose 11 from the discharge port of the hydraulic cylinder 6a having a reserve tank (not shown).
It is connected to the front brake device 12 by.

負圧室と夫々連通している。 Each chamber 2a, 2b, 2c in the vehicle body frame 1 communicates with an intake manifold 14, which is a negative pressure source, via a hose 13a, 13b, 13c, and each chamber 2a, 2b, 2c is connected to a vacuum hose 1.
It communicates with the negative pressure chamber of the negative pressure booster 6 via 5a, 15b, and 15c, respectively.

こともできる。 As described above, in this invention, the constituent pipes of the vehicle body frame are connected airtightly to form multiple independent chambers, and each chamber is used as a vacuum tank, so the volume can be increased. Therefore, even if the negative pressure booster is used frequently, there is no risk of a decrease in negative pressure, and there is no need to newly install a vacuum tank, so the weight of the vehicle can be reduced.
