Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a flexible hose wiring structure, such as a brake hose, which is installed between a fixed side and a moving side that moves vertically and horizontally.

[Prior Art] As shown in FIG. 6, the brake body 11 disposed on the wheel side 4a is supplied with pressure oil (brake oil) from a pressure source 12 provided on the vehicle body side 3a. A fixed pipe 15 is installed between the hydraulic port 13 provided on the brake body 11 side and the mounting bracket 6a fixed to the shock absorber 14 on the wheel side 4a. Further, between the mounting bracket 5a fixed to the vehicle body side 3a and the mounting bracket 6a on the shock absorber 14 side, a flexible member such as a brake hose 1 made of a rubber hose is provided.
Is erected. A fixed pipe 16 is connected between the mounting bracket 5a and the pressure source 12. The wheel side 4a reciprocates in the up-down direction and moves left and right by the tire cutting angle when changing directions. The brake hose 1 needs to be routed with an appropriate slack so that the brake hose 1 does not fully extend even when the brake hose is moved up and down and left and right, and is formed of a flexible member as described above.

FIG. 7 shows a conventional wiring structure of the brake hose 1, and the brake hose 1 is usually installed between the mounting brackets 5a and 6a without twisting the axis thereof.

[Problems to be Solved by the Invention] The space in which the brake hose 1 is installed is generally narrow, and since there are various types of peripheral members such as brackets and mounting bolts, the brake hose 1 interferes with them. Fear arises. In particular, when the brake hose 1 is routed as shown in FIG. 7, the operation range of the brake hose 1 is widened, and the risk of interfering with peripheral members increases. Therefore, it is necessary to reduce the space in the engine room, the trunk room, etc., and prevent the brake hose 1 from interfering with each other.

In the prior art, Japanese Patent Laid-Open No. 57-8 discloses a solution to the above problems.
Some are disclosed in 0961. This technology supports the supporting part of the hose bracket of the brake hose installed between the vehicle body side and the wheel side in the front-back direction of the wheel,
It has a structure in which the brake hose is bent in a horizontal U-shape that is convex in either the front or rear direction. This prevents the brake hose from significantly tilting toward the vehicle body side and the wheel side even when the vehicle body side and the wheel side support points are brought close to each other when the wheel is moved up and down or when steering, saving space and preventing interference. The effect of can be improved. However, this technique cannot be applied to all vehicles, and depending on the vehicle structure, it is difficult to install the brake hose in the above state as it is, and it is necessary to newly provide a special member.

The present invention is small in vibration due to vertical and horizontal movements of wheels, can save space, can save a large space in an engine room or a trunk room, and can be implemented easily and inexpensively for all vehicles. An object is to provide a flexible hose wiring structure.

[Means for Solving the Problems] In order to achieve the above object, the present invention fixes one mounting end to a fixed side and the other mounting end to a moving side that moves up and down and left and right. A flexible hose wiring structure is formed by attaching any one of the mounting ends of a flexible hose to the other mounting end in a twisted state.

[Operation] The flexible hose is installed between the fixed side and the moving side in a twisted state in a free state in which there is no vertical movement or horizontal movement.
For this reason, bending rigidity and torsional rigidity are increased, and blurring during movement is suppressed.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

FIGS. 1 and 2 show a state in which the brake hose 1 is twisted and installed in a direction away from the obstacle 2 when there is a fixed obstacle 2 in the vicinity of the arrangement of the brake hose 1. is there. That is, when the brake hose 1 is installed as it is, it is installed in a straight line between the fixed side 3 (vehicle body side) and the moving side 4 (wheel side). It is possible to move away from 2, and the risk of interference is reduced accordingly.

FIG. 3 shows a state in which the mounting bracket 5 on the fixed side 3 and the mounting bracket 6 on the moving side 4 are twisted by an angle θ when mounted, and the brake hose 1 is bent into a wavy shape as shown in the drawing. Can be installed. As a result, the rigidity is increased as compared with the case where the mounting brackets 5 and 6 are mounted in a straight line, and the blur of the brake hose 1 with respect to the displacement on the moving side 4 is reduced.

As shown in FIG. 4, the brake hose 1 comprises a hose portion 7, end fittings 8 formed at both ends of the hose portion 7, and a screw portion 9 extending from the end fitting.

On the other hand, as shown in FIG. 5, the mounting brackets 5 and 6 are formed with elongated holes 10 into which the end fittings 8 are fitted. For the brake hose 1, attach the end fitting 8 to the long holes 10 of the mounting brackets 5 and 6.
And is fixed to the mounting brackets 5 and 6 with the screw portion 9 and attached. Therefore, the brake hose 1 can be attached by twisting the hose portion 7 by inclining the end fitting 8 or the elongated hole 10.

4 (a), (b), and (c), the end fitting 8 on the right side of the drawing is tilted by an angle θ and fixed to the hose portion 7. Further, FIG. 5 shows a case in which the elongated hole of the mounting bracket 6 is inclined by an angle θ. Therefore, the mounting bracket having the long hole 10 which does not incline the brake hose 1 shown in FIG.
When the brake hose 1 is installed and fixed between 5 and 6, the brake hose 1 is twisted by that amount, and the brake hose 1 having the end fitting 8 which does not incline to the opposite is attached to the mounting bracket shown in FIG.
When it is installed and fixed between 5 and 6, a twist corresponding to the angle θ of the mounting bracket 6 is given. Of course, as shown in FIG. 4, the brake hose 1 having the inclined end fitting 8
May be attached to a mounting bracket 6 having a slender elongated hole 10 as shown in FIG.
The brake hose 1 in which both end fittings 8 are inclined is fixed by being installed between the mounting brackets 5 and 6 having the non-inclined elongated holes 10 or both the mounting brackets 5 and 6 having the inclined elongated holes 10. Of course, it does not matter even if a twist is given.

The rigidity can be increased by twisting the brake hose 1 as described above, but the initial stress acts on the brake hose 1 to that extent. Then, the movement of the brake hose 1 changes in the vertical and horizontal directions, and the stress acts. Therefore, if the curvature is too small, the brake hose 1 may be buckled.
Therefore, even if the curvature of the brake hose 1 is the smallest, the inner radius of the brake hose 1 is
It is necessary to set the angle θ so that it is 10 mm or more.

It has been proved that the above wiring structure suppresses the shake of the brake hose 1 within a range of several mm to 10 mm.

Although this embodiment has described only the brake hose,
It can also be applied to electrical wire harnesses, piping such as vinyl tubes, and wiring.

[Effects of the Invention] As is clear from the above description, according to the present invention, the following effects can be obtained.

(1) Since the flexible hose is twisted and attached to the fixed side and the moving side, the rigidity is increased, and the shake of the flexible hose can be suppressed to a small amount with respect to vertical movement and lateral movement on the moving side.

(2) Since the shake is reduced, the space can be saved correspondingly, and the space of the engine room and the trunk room can be increased.

(3) The present invention imparts an initial twist to the brake hose at the time of installation, does not require a special member, can be implemented easily and inexpensively, and can be applied to all vehicles as it is.
