DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for holding a hydraulic tube arranged in an engine room of a vehicle.

[0002]

2. Description of the Related Art In a conventional vehicle, a brake tube extending from a brake master cylinder or the like in an engine room is arranged in a lateral direction of the vehicle along a wall of the engine room. Install a special protector between the engine and the engine, especially its accessories, so that it does not interfere with the brake tube, or the pressure oil in the brake tube may be damaged by heat dissipated from the engine. It is necessary to cover the brake tube with a heat shield so as not to receive it, and because the protector and heat shield are provided, the structure in the engine room becomes complicated and maintenance is difficult. In addition to having an adverse effect, there was a problem that the appearance in the engine room also deteriorated.

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a simple structure in which a hydraulic tube arranged in an engine room of a vehicle interferes with equipment in the engine room,
The purpose is to prevent heat damage.

[0004]

SUMMARY OF THE INVENTION Therefore, a holding apparatus for a hydraulic tube according to the present invention includes a dash panel for separating a vehicle compartment and an engine room, a dash silencer attached to the dash panel on the engine room side, and the dash panel. includes a holder for holding the hydraulic tubes disposed between the dash panel and the dash silencer, air layer is formed between the upper Symbol dash silencer and the retainer.

[0005]

[Action] That is, they are arranged holder for holding the hydraulic tubing between the dash panel and the dash silencer, since the air layer is formed between the dust Tsu shoe silencer and the holder, the hydraulic tube holder When it is held by the existing dash silencer, the engine room side is covered and protected from the equipment in the engine room, and the heat damage to the hydraulic tube is automatically prevented, so the hydraulic tube protector and heat shield plate Becomes unnecessary, and it can be suppressed that the inside of the narrow engine room is further narrowed to protect the hydraulic tube.

[0006]

BRIEF DESCRIPTION OF THE DRAWINGS FIG.
The same parts will be described with the same reference numerals. 1 to 3, a dash panel 3 that separates a vehicle compartment 1 from an engine room 2 has an engine room 2 on the engine room 2 side.
A plate-shaped dash silencer 4 that suppresses noise inside the vehicle from being transmitted to the vehicle interior 1 is arranged, and a recess 5 extending in the lateral direction of the vehicle is formed on the vehicle interior 1 side of the dash silencer 4. A plurality of weld bolts 6 fixed to the dash panel 3 at intervals in the lateral direction elastically penetrate the boss portions 8 of the resin tube clips 7 arranged in the recesses 5, respectively. And the resin clip 9 is pressed into the tip of the weld bolt 6 or the nut is screwed in, so that the dash silencer 4 is fixed to the dash panel 3 and each tube clip 7 is inserted into the recess 5. Supported by.

[0007] Each tube clip 7 is formed with a claw 10 which extends from a brake master cylinder 11 installed in the engine room 2 or is not shown in the case where the brake lines for the front and rear wheels are in the X arrangement. Brake tubes 12 extending from the dual type proportioning valve are respectively disposed in the recesses 5 of the dash panel 3 and retained by engaging with the claws 10 of the respective tube clips 7. As a result, an air space 13 is secured between the dash silencer 4 and the brake tube 12.

In the above device, the brake tube 1
Since the engine room 2 is covered with the existing dash silencer 4 on the engine room 2 side, the brake tube 12 is protected from interference with engine accessories during engine rolling and when the engine is mounted in the engine room 2. The brake tube 12 is also prevented from being damaged during maintenance of the engine, and the dash silencer 4 automatically protects the brake tube 12 from heat damage, so a protector and a heat shield for the brake tube 12 are separately provided. There is no need at all, and therefore, the inside of the narrow engine room 2 is not further narrowed to protect the brake tube 12 and the like, so that the structure inside the engine room 2 is simplified, and the maintainability can be easily improved. ,
In addition, the appearance in the engine room 2 can be improved.

Further, since the air layer 13 is secured between the dash silencer 4 and the brake tube 12 by the tube clip 7, the action of the dash silencer 4 to prevent the heat damage of the brake tube 12 is caused by the air layer 13. The presence becomes more remarkable, and there is an effect that the brake tube 12 can be reliably protected from the heat in the engine room 2.

Further, the tube clip 7 for holding the brake tube 12 is supported by the weld bolt 6 for fixing the dash silencer 4 to the dash panel 3, and there is no need to separately install a support mechanism. And the cost increase can be easily suppressed.

[0011] When it is necessary to install a retaining clip of the brake tube 12 in a fixture with different positions of the dash silencer 4 against the dash panel 3, as shown in FIG. 4, car dash silencer 4 Room
Tube clips 7 holding the brake tubes 12 are arranged at intervals in the lateral direction of the vehicle in recesses 5 formed on one side and extending in the lateral direction of the vehicle, and the resin clips attached to the dash silencers 4 respectively. When the clip 20 elastically passes through the tube clip 7, the tube clip 7 is supported in the recess 5, and each brake tube 12 is inserted into the recess 5 while securing an air layer 13 between the tube clip 7 and the dash silencer 4. And, as in the previous example,
The dash silencer 4 protects the brake tube 12 and prevents heat damage thereof.

A shielding member is disposed continuously from the dash silencer on the engine room side along the body panel on the left front side of the dash panel, and a brake tube extending from the dash panel to the left front wheel is provided between the body panel and the shielding member. Even if it is arranged to be held by a holder equivalent to the brake tube holder in each of the above embodiments, the same operation and effect as those of the above embodiments can be obtained, and It goes without saying that the clutch tube may be held similarly instead.

[0013]

In the hydraulic tube holding device according to the present invention, the hydraulic tube disposed in the engine room of the vehicle is protected from the equipment in the engine room by the existing dash silencer, and the heat damage to the hydraulic tube is prevented. Is also automatically prevented, so there is no need for a protector or heat shield for the hydraulic tube. Therefore, it is possible to easily prevent the hydraulic tube from interfering with the equipment in the engine room or receiving heat damage by a simple configuration. be able to.
