Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an intermediate fitting for a brake hose. More specifically, the present invention relates to an intermediate metal fitting for a brake hose (hereinafter simply referred to as an intermediate metal fitting) for suitably fixing an intermediate portion of a brake hose used for a vehicle or the like to another member (vehicle body or the like).

[0002]

[Prior Art]

 A brake hose for an automobile has one end connected to a caliper and the other end connected to a hydraulic source such as a master cylinder. Then, the brake hose (generally made of rubber) may repeatedly come into contact with other members such as the differential gear due to the vibration of the automobile, and that part may be damaged, causing problems such as oil leakage. On the other hand, due to recent changes in vehicle body structure, suspension design issues, etc., there is a demand in the automobile industry to change the extension direction of the brake hose at a steep angle.

A bent metal pipe is used as a brake hose that satisfies the above requirements and is fixed to another member to suppress vibrations. A brake hose with a fixed hose, so to speak, with an intermediate pipe is known. In such a conventional brake hose with an intermediate pipe, a mounting portion for forming another member such as a groove or a collar is formed on the outer periphery of the brake hose fixing metal fitting on one end side of the intermediate pipe.

[0004]

[Problems to be solved by the device]

 In the above conventional brake hose, since the attachment part to other members is limited to the vicinity of the one connection part between the intermediate pipe and the brake hose, it is difficult to position in a narrow space, so it takes time and effort to attach it. . There are also cases where it cannot be installed. Further, it is notable that vibration of the intermediate pipe itself cannot be prevented and is damaged by fatigue, which is remarkable especially in the case of a long intermediate pipe. In addition, when it is necessary to bend multiple points of the intermediate pipe, it is extremely difficult to install.

The present invention has been made to solve such a problem, and an object thereof is to provide an intermediate metal fitting that effectively suppresses vibration of the intermediate metal fitting itself and is extremely easy to mount.

[0006]

[Means for Solving the Problems]

 The brake hose intermediate fitting of the present invention includes a curved metal tube, brake hose fixing fittings provided at both ends of the metal tube, and at least one other member fixed to an intermediate portion of the metal tube. And a mounting member.

The mounting member may be made of a metal plate-shaped member having mounting holes, and may be fixed to the metal pipe by brazing.

[0008] Fixing portions for other members may be formed at both ends of the metal tube, which are connected to the brake hose fixing fitting, respectively.

[0009]

[Action]

 Since the intermediate metal fitting of the present invention fixes the attachment member to the intermediate portion of the metal tube, it can be attached at an appropriate location and can suitably cope with various design changes. When it is necessary to use a longer metal tube and when it is necessary to bend the metal tube in a three-dimensionally complicated manner, it is possible to cope with the situation by providing a plurality of mounting members. Moreover, there is an advantage that the vibration of the intermediate fitting can be effectively suppressed as compared with the conventional intermediate pipe fixed only at one end side.

[0010]

【Example】

 Next, the intermediate fitting of the present invention will be described with reference to the accompanying drawings.

FIG. 1 is a partially cutaway perspective view showing an embodiment of an intermediate fitting of the present invention, FIG. 2 is a perspective view showing a state where a brake hose is fixed to the intermediate fitting of FIG. 1, and FIG. 3 is an intermediate view of the present invention. It is a perspective view showing other examples of metal fittings.

In FIG. 1, reference numeral 1 denotes an intermediate metal fitting, and fixing metal fittings 3 for fixing a brake hose are respectively connected to both ends of a curved metal pipe 2 at two positions, and an intermediate portion of the metal pipe 2. The attachment member 4 to another member is fixedly attached.

The fixture 3 is a double pipe as shown, and the inner diameter of the inner pipe 5 is substantially the same as the inner diameter of the metal pipe 2. Then, as shown in FIG. 2, after the brake hose H is inserted into the gap between the inner pipe 5 and the outer pipe 6, the outer hose of the outer pipe 6 is clamped to be caulked. The outer pipe 6 and the inner pipe 5 are connected to each other and the fixing metal member 3 and the metal pipe 2 are connected to each other by brazing or the like.

As shown in FIG. 1, the mounting member 4 is composed of a plate-shaped metal member having a mounting hole 7 formed therein, which is also fixed to the metal tube 2 by brazing or the like. Then, a bolt or the like is inserted into the mounting hole 7 and fixed to a bracket or a machine frame (not shown) of another member.

In the present embodiment, the metal tube 2 is curved at two places, and one mounting member 4 is fixed to the intermediate portion of the curved portions at the two places. It is not limited to. It can be appropriately changed according to the mounting space of the intermediate metal fittings and the type of the mating member. For example, the curved portion of the metal pipe may be provided at one place, or at three or more places, and the attachment member may be fixed to two or more at appropriate places of the metal pipe.

As described above, if the intermediate fitting 1 is used, it is possible to easily cope with the case where the brake hose needs to be complicatedly curved in the engine room of the vehicle. Also, no matter how long the intermediate fitting is, it is possible to suitably suppress the vibration.

The intermediate metal fitting 11 shown in FIG. 3 has, in addition to the above-mentioned mounting member 4, both brake metal fittings 12 of the brake hose, and fixing portions 13 to other members. This fixing part is composed of a groove 14 and a collar 15 formed on the outer periphery of the fixing metal fitting 12, and has a convenient shape for fixing to another member (not shown) with a fixing band, a hook or a wire. Has been done. Since it is effectively fixed using the mounting member 4, it is not necessary to use the fixing portion 13 unless it is particularly necessary.

[0018]

[Effect of the device]

 The intermediate fitting of the present invention can easily cope with various bending postures required for the brake hose, can be easily attached to other members, and can further effectively suppress the vibration.
