JP2510697Y2 - Front fork - Google Patents

Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a front fork that serves as both a shock absorber and a fork that is interposed between the body of a motorcycle and the axle and that damps vibrations from the road surface, and in particular the front The present invention relates to a mounting device for a fender mounting bracket provided on a fork.

[Prior Art] As this type of front fork A, for example, one having a structure shown in FIG. 2 has been developed.

This is because a wheel side tube 2 is slidably inserted in a vehicle body side tube 1, an axle bracket 3 is inserted in the lower outer periphery of the wheel side tube 2, and a brake caliper mounting boss 4 is attached to the axle bracket 3. The fender mounting boss 5 is integrally provided.

The brake caliper is attached to the boss 4 and arranged so as to fit inside the wheel, and the mudguard fender is arranged above the wheel via the boss 5.

[Problems to be Solved by the Invention] When replacing a wheel, it is necessary to remove the wheel from the vehicle body, but a fixed fender is connected to the axle bracket 3 via a boss 5, while the other boss is used. Four
Since the brake caliper attached via the is located inside the wheel, it will interfere with the brake caliper when the wheel is removed.

Therefore, since the axle bracket 3 cannot move, it is necessary to remove the brake caliper from the boss 4 and then remove the wheels. On the contrary, in order to attach the wheels, it is necessary to attach the wheels first, and then attach the brake caliper to the boss 4, which makes the attaching and detaching work of the wheels very troublesome.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a new front fork that does not require the brake caliper to be attached / detached at the time of attaching / detaching a wheel and has improved operability.

[Means for Solving the Problems] In order to achieve the above object, the structure of the present invention is such that a wheel tube is slidably inserted into a vehicle body tube, and a bracket for mounting a fender is provided on the outer periphery of the wheel tube. In a front fork equipped with an axle bracket, insert a stopper on the outer periphery of the wheel side tube while facing the axle bracket, rotatably insert a fender mounting bracket on the outer periphery of this stopper, and place the lower part of the stopper on the axle bracket. It is characterized in that it is screwed onto the inner periphery of the upper part of the stopper so that the bracket for mounting the fender is sandwiched between the flange of the stopper upper part and the upper end of the axle bracket.

[Operation] Since the axle bracket can rotate independently of the fender mounting bracket, the axle bracket can be rotated to a position where it does not interfere with the wheels while the brake caliper is attached when the axle is replaced.

[Embodiment] A front fork according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 shows an embodiment of a front fork according to the present invention.

The front fork according to the present invention includes a vehicle body side tube 1
The inner tube, which is the wheel-side tube 2, is slidably inserted into the outer tube, which is the same as the prior art shown in FIG. 2, which constitutes the inverted front fork A. The vehicle-body-side tube 1 is attached to the vehicle body through the bracket. The wheel-side tube 2 is connected to the wheel via the eye 6.

A cylindrical axle bracket 7 is inserted in the lower outer periphery of the wheel-side tube 2, the brake caliper mounting bosses 9, 9 are integrally provided on the axle bracket 7, and a large diameter portion 7a is provided above the axle bracket 7. Step 8
And are formed. The axle bracket 7 may be formed integrally with the eye 6. Although a screw is engraved on the inner circumference of the large diameter portion 7a, a screw is simply engraved on the inner circumference of the upper portion of the axle bracket 7 and an arbitrary annular gap is provided between the upper portion and the wheel side tube 2. You can keep it.

A cylindrical fender mounting bracket 10 is provided on the outer circumference of the wheel side tube 2, and a stopper 11 is arranged between the inner circumference of the bracket 10 and the outer circumference of the wheel side tube 2. The bracket 10 and the stopper 11 are inserted into the outer circumference of the wheel side tube 2 in advance before mounting the axle bracket 7.

A screw 11a is engraved on the outer periphery of the lower portion of the stopper 11, and an engaging portion 11 formed of a groove or a hole is formed on the upper portion of the stopper 11.
A collar 11b having c is provided, and the large-diameter portion 7a of the axle bracket 7 is rotatably engaged with the screw 11a by rotating the stopper 11 by biting a tool on the locking portion 11c. ing.

As a result, the fender mounting bracket 10 is sandwiched between the collar 11b and the upper end of the axle bracket 7, and the fender mounting bracket 10 is prevented from slipping upward.

The bracket 10 has bosses 12 and 12 for mounting fenders.
Are provided integrally.

When mounting or removing the wheel from the vehicle body, the axle bracket 7 is rotated so that the brake caliper does not interfere with the wheel. When the axle bracket 7 is formed integrally with the eye 6, the eye 6 is removed from the axle and the axle bracket 7 and the eye 6 are rotated together.

Since the fender mounting bracket 10 is installed between the two front forks A and A, the bracket 10 itself does not rotate.

Therefore, for example, when removing a wheel, the axle bracket 7 is rotated, the brake caliper connected to this bracket 7 is rotated to a position where it does not interfere with the wheel, and then the wheel is extracted.

[Effect of the Invention] According to the present invention, the bracket for mounting the fender and the axle bracket are separated, and both are relatively rotatably screwed together. Therefore, even if the bracket for mounting the fender is fixed, the axle bracket is fixed. Only can rotate alone. Therefore, when removing the wheels from the vehicle body or when attaching the wheels to the vehicle body, the positions of the axle bracket and the brake caliper attached to the axle bracket can be rotated and displaced with respect to the attachment / detachment direction of the vehicle body, and the brake caliper interferes with the wheel. do not do. Therefore, it is only necessary to rotate the axle bracket when attaching and detaching the wheels, which has the advantage of significantly improving operability.
