Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an automobile brake hose, and more particularly to a brake hose having an intermediate fitting.

[0002]

[Prior art]

 Brake hoses for automobiles are supplied with joint fittings fastened at both ends by caulking, etc., and are assembled to predetermined parts of the automobile body on an assembly line. However, the installation space for the brake hose is extremely limited, and in recent years various sensors and harnesses have been assembled together, making the assembly process more and more complicated.

Therefore, in terms of performance, it is desired to develop a brake hose which has sufficient reliability similar to the conventional one and is further excellent in assembling workability. By the way, with one brake hose having joint fittings fastened at both ends, the hose may be bent more than necessary and buckled when it is installed by bypassing an obstacle in the middle. Even if the buckling does not occur, it is extremely difficult to assemble the both ends by bypassing the obstacle.

Therefore, for example, Japanese Utility Model Publication No. 60-128856 discloses a brake hose having a structure in which two hoses are connected by an intermediate fitting having a bent pipe. According to the brake hose thus connected by the intermediate metal fitting, it is possible to assemble around the obstacle without deforming the hose which causes buckling.

[0005]

[Problems to be solved by the device]

 However, in the conventional brake hose as disclosed in the above publication, both ends of the intermediate metal fitting are fastened to the hose by crimping. Since the workability is extremely poor if the caulking is performed on the assembly line of the automobile, such a brake hose is generally supplied with the hoses previously crimped and fastened to both ends of the intermediate fitting. Then, on the assembly line, it is only necessary to assemble the fittings on both ends of the brake hose to other parts.

However, it is difficult to assemble the brake hose bent at such an intermediate portion, and it may be difficult to bypass the obstacle in a small work space. The intermediate metal fitting is usually held by a clip or E-ring on a bracket or the like extending from the vehicle body. However, in this case, it is necessary to insert the hose into the mounting hole of the bracket from one end and move the hose by the length up to the intermediate metal fitting, and it cannot be said that the assembling workability is good either. In addition, the protruding brackets hindered the assembly work and the number of parts such as clips increased.

The present invention has been made in view of such circumstances, and an object thereof is to further improve the workability of assembling a brake hose having an intermediate fitting.

[0008]

[Means for Solving the Problems]

 The brake hose of the present invention for solving the above-mentioned problems includes a first hose, a cap portion fixed to one end of the first hose, a bending pipe integrally formed with the cap portion, and the other end of the bending pipe and the bending pipe. An intermediate metal member formed of a first threaded joint portion integrally formed with the first threaded joint portion and a bracket formed integrally with the first threaded joint portion and protruding from the first threaded joint portion; A second hose that is fixed to a second screw joint part that is screwed to the joint part, and a second hose that is screwed to the first screw joint part and connected to the intermediate metal fitting. And

[0009]

[Action]

 In the brake hose of the present invention, one end of the intermediate fitting is the first screw joint portion. Therefore, when assembling this brake hose to the vehicle body, the first hose having the intermediate fitting is first assembled to the vehicle body with the first screw joint portion and the second screw joint portion separated, and then the first screw joint portion is assembled to the vehicle body. The second screw joint portion and the first screw joint portion are screwed together while the first screw joint portion is held by a wrench or the like to prevent rotation. The end of the second hose opposite the end with the second threaded joint is usually assembled to the vehicle body thereafter.

Further, in the brake hose of the present invention, the bracket projects from the first screw joint portion. Therefore, by attaching this bracket to the vehicle body with bolts or the like, the intermediate fitting can be directly assembled to the vehicle body. That is, since the intermediate metal fitting can be assembled to the vehicle body before the second screw joint portion is screwed into the first screw joint portion, it is easier to handle as compared to the conventional integrated brake hose. It will be easy. Moreover, if the bracket is temporarily fixed, it is easy to adjust the overall position when the second screw joint portion is screwed.
