Description

[Detailed Description of the Invention] The present invention particularly relates to an improvement of a brake hose clamp provided on the front fender of a tricycle or the like.

A brake mechanism, particularly a front brake mechanism, in a tricycle or the like uses a brake hose to connect a brake lever attached to a handle grip and a brake caliper that sandwiches a brake disc attached to a front wheel. This brake hose is held by a clamp on a part of the vehicle body.

By the way, when the front fender is attached and fixed to the lower part of the bottom bridge, a clamp is attached to the side of the fender to loosely insert and hold the brake hose so that the brake hose does not loosen and protrude to the side of the vehicle when the front wheel moves up while driving. It is formed in one piece.

Conventional clamps of this type have been integrated with the front fender to form a loose insertion hole for the brake hose in consideration of the moldability of the front fender, but they have the following drawbacks. That is, when assembling a tricycle, for example, it is easier to assemble the front fender after assembling the brake hose, etc., but this cannot be done with the conventional clamp structure, resulting in poor assemblability. In addition, it is not easy to remove or install the clamp structure during maintenance, and although moldability is taken into consideration, there are significant disadvantages in terms of ease of assembly, ease of maintenance, etc.

The purpose of the present invention is to eliminate such defects, and to provide a clamp for a vehicle brake hose that can be molded into one piece, hardly increases the cost of molding, and is easy to assemble and maintain. .

In order to achieve this purpose, the present invention is applied to a clamp for a brake hose of a vehicle, such as a tricycle, in which a guide slit is formed on the side of a front fender, and its main structure is as follows. One end of the clamp is formed integrally with the fender, the other end is made detachable from the fender by screwing, etc., and the brake hose is taken in from the other end of the clamp,
It is characterized by being removable.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

In the drawings, Fig. 1 is a schematic perspective view of a tricycle to which the brake hose clamp according to the present invention is applied, Fig. 2 is a side view of the front part of the tricycle showing the front brake mechanism, and Fig. 3 is a schematic perspective view of the tricycle to which the brake hose clamp according to the present invention is applied. FIG. 3 shows a perspective view of the brake hose clamp according to the invention.

First, in order to clarify the present invention, the schematic structure of a tricycle will be explained with reference to FIG. The tricycle designated by reference numeral 1 has a body frame 2, and the front part of the body frame 2 is equipped with a head pipe 3 (Fig. 2), and this head pipe 3 has both top and bottom bridges 4 and 5. A front fork 6 is supported, a front wheel 7 for steering is supported at the lower part of the front fork 6, and a handle 8 is attached to the upper part of the top bridge 4. On the other hand, the engine 9 is mounted on the lower part of the vehicle body frame 2, and
A pivot point was extended to the rear at the lower rear. A pair of left and right driving rear wheels 10, 10 are supported by a rear fork,
A shock absorber is interposed between the rear fork and the body frame 2, and a fuel tank 11 is located at the front of the upper part of the body frame 2, and a seat 1 is located behind this.
2 is attached to each. The front fork 6 is composed of a pair of left and right front fork members 13, 14. The lower parts of the front fork members 13, 14 are vertically movable bottom cases 15, 16, and the upper parts are fixed fork pipes 17, 18. Both the top and bottom bridges 4 and 5 are installed between the fork pipes 17 and 18, and a front fender 19 is attached to the bottom of the bottom bridge 5. On the other hand, a brake lever 20 is disposed near the grip 8a of the handle 8, and a brake caliper 23 that sandwiches a brake disc 22 attached to the axle 21 of the front wheel 7 is connected to the lever 20 by a brake hose 24. It constitutes a brake mechanism 25. In addition. Reference numeral 26 indicates a headlight.

Next, the brake mechanism 25 and the main parts of the present invention will be specifically explained with reference to FIGS. 2 and 3. Note that the same parts are given the same reference numerals throughout each figure to clarify the structure.

First, a master cylinder 27 (FIG. 1) is disposed on the handle 8 near the brake lever 20, and the upper end of the brake hose 24 is connected to this. The brake hose 24 goes downward and is first held and fixed by an upper clamp 28 fixed to the bottom bridge 5 whose position relative to the master cylinder is immovable.
It is held by a clamp 29 according to the present invention provided at the top and extends downward. The lower part of the brake hose 24 is held and fixed by a lower clamp 30 provided on the bottom case 15, which is movable relative to the upper clamp 28, and the lower end of the brake hose 24 is connected to a brake caliper 23 fixed to the bottom case 15. join to. This brake mechanism 25 is hydraulic, and the brake hose 24 is formed as a tube having an oil passage inside. However, brake lever 2
By operating 0, the brake caliper 23 and the brake disc 22 come into frictional contact and exhibit a well-known braking function of braking the brake disc 22.

Now, in Fig. 2, the front wheel 7 moves upward while driving.
Assume that the vehicle has moved to the position of the front wheel 70 indicated by the imaginary line. In this case, the lower clamp 30 is also clamp 300.
The brake hose 24a between the upper clamp 28 and the lower clamp 30 is loosened, for example, as a brake hose 240a shown by a phantom line.
Therefore, due to this slack, the brake hose 24
0a is held by the clamp 29 so that it does not protrude to the side of the vehicle body.

Such a clamp 29 is constructed according to the present invention, and preferably includes a connecting line between the upper and lower clamps 28 and 30 at the rear side of the front fender 19, and extends a predetermined distance rearwardly from the line as in the embodiment. Form across the width. Specifically, front fender 1
The front end of an elongated clamp piece 31 along the side of the clamp piece 9 is bent inward to be integrally formed with the front fender 19, and a mounting piece 33 having a mounting hole 32 is integrally formed inside at the rear end. . On the other hand, for example, a recess 34 is provided on the side of the front fender 19 corresponding to the mounting piece 33, and a bracket 36 having a mounting hole 35 corresponding to the mounting hole 32 is integrally formed within this recess 34.

With this structure, the rear end of the clamp piece 31 becomes a free end, and since the clamp piece 31 is relatively long and thin, it moves elastically in the direction of the arrow A-A', and when moved inward, the clamp piece 31 and the bracket are connected to each other. 3
6 overlap, and the respective mounting holes 32 and 35 are arranged coaxially. However, the mounting holes 32 and 35
Insert the collar 37 into the collar 37, pass the bolt 38 through the collar 37, and tighten with the nut 39 to form a guide slit S, which is a space closed by the clamp piece 31, and the brake hose is inserted into the slit S. 24a is inserted loosely. In addition, such a clamp 29 includes a collar 37, a bolt 38, and a nut 39.
Front fender 19 by press molding etc.
It can be integrally molded, or it can be attached separately by welding or the like.

Therefore, attach the rear end of the clamp piece 31 to the bracket 3.
6 and open outward, the brake hose 24a can be easily installed and removed from here. When the brake hose 24a is held by the clamp 29, the brake hose 24a
a can freely move back and forth within the slit S. Moreover, the upper and lower clamps 28 and 3
0. In addition, since the clamp 29 is disposed substantially in a straight line, the brake hose 24a can be smoothly bent.

In addition, although the above embodiment is applied to a three-wheeled motor vehicle, it can also be applied as a brake hose clamp for other vehicles in general, including two-wheeled motor vehicles, and arbitrary changes to the shape etc. are beyond the scope of the present invention. It's not something to deviate from.

As is clear from the above explanation, the brake hose clamp according to the present invention has one end of the clamp integrated with the fender, and the other end is configured to be detachable from the fender by screwing, etc., so it is easy to assemble. In other words, the fender can be attached after the brake mechanism including the brake hose has been assembled, and the ease of assembly can be improved by simplifying the assembly work.

Further, the fender can be easily removed and attached during maintenance, and the degree of freedom can be increased.

Furthermore, although it has the above advantages, it can be implemented at conventional levels in terms of moldability, and there is almost no increase in cost, so that it can be provided as a clamp for a brake hose for a vehicle that has excellent practical value.
