Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial field of application) The present invention relates to a cable guide device for a motorcycle using an inverted front fork.

(Prior Art) Generally, in a motorcycle, a meter cable for driving a speedometer thereof is arranged so as to be parallel to a front fork from a rotary take-out portion attached to a front wheel. Therefore, when the vehicle actually travels, there is a problem in that the front fork expands and contracts, so that the cable has play and is caught in the tire.

Therefore, conventionally, a cable guide is provided on a front fender or the like.

That is, FIG. 3 is a partial view of the front fork portion of the conventional motorcycle, in which the inner tube fixed to the upper bracket 3 and the lower bracket 4 is attached to the outer tube 2 having the front wheel 1 attached to the lower end. The lower end of the tube 5 is elastically inserted.

The front wheel 1 is equipped with a rotary take-out portion 6, and the lower end portion of a meter cable 7 is connected to the rotary take-out portion 6. The meter cable 7 extends upward along the outer tube 2 of the front fork and is provided with a cable guide 9 provided on the front fender 8.
Guided by the top of the steering shaft 10
Is connected to a speedometer 11 mounted on the upper side of.

Even if the front wheel 1 moves up and down while traveling, the meter cable 7 is guided by the cable guide 9, so that the cable is not caught in the front wheel 1 or the like.

Further, in an off-road type motorcycle, the suspension stroke is large and the movement of the meter cable 7 is large. Therefore, in this case, the outer tube 2 is provided with a cable guide extending rearwardly.

(Problems to be solved by the invention) However, in the case of an off-road vehicle that uses an inverted front fork in which the upper part of the inner tube with the front wheel attached to the lower end is elastically inserted into the outer tube, Since the inner tube that makes the same movement is the sliding portion, it is impossible to provide a cable guide on it. Further, when the guide is projected from the axle holder part to the vicinity of the tire, the guide becomes too long, and there is a problem in that the guide comes into contact with other parts during traveling or the like.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a cable guide device capable of reliably guiding and protecting a cable even in an off-road vehicle using the inverted front fork.

[Constitution of device]

(Means for Solving the Problem) In a cable guide device for an inverted fork truck in which an upper portion of an inner tube having a front wheel attached to a lower end portion is telescopically inserted into an outer tube, a cable guide device for an inverted fork truck is provided with two long and short portions below the outer tube. The loop-shaped cable guide is attached, and the cable guide with a long length in the direction orthogonal to the center line of the front fork is arranged above and the cable is inserted through both cable guides. And

(Operation) While the vehicle moves up and down, the cable also moves up and down, but in this case, the cable is guided and protected by the cable guide, and the cable is prevented from being caught in the front wheel or the like. Moreover,
Since the lower cable guide of the upper and lower cable guides has a shorter length in the direction orthogonal to the center line of the front fork, the cable is more slack in the upper cable guide portion, and the cable is wheel-shaped. Surely protected against.

(Embodiment) An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

FIG. 1 is a side view of the motorcycle for off-road use, in which a front wheel 22 is suspended at the lower end of an inverted front fork 21 steered by a bar handle 20.

That is, the outer tube 25 is fixed to both sides of the upper bracket 23 and the lower bracket 24 to which the bar handle 20 is attached, and the upper portion of the inner tube 26 is inserted into the outer tube 25 from below so that the upper tube can extend and contract. Has been done. A front wheel 22 is suspended from the lower end of the inner tube 26, and a front fender 27 that covers the front wheel 22 is attached to the outer tube 25.

A vertically long plate-shaped protector 28 is disposed on the front side of the inner tube 26. The lower end of the protector 28 is fixed to the lower end of the inner tube 26, and the upper part of the protector 28 is slidably inserted and supported in the guide hole by the guide member 29 mounted on the outer tube 25.

By the way, on the guide member 29, two loop-shaped cable guides 30a and 30b are provided so as to protrude rearward.
The two cable guides 30a and 30b are arranged one above the other, and the upper cable guide 30a has a relatively long length in the direction orthogonal to the axis of the front fork 21 and is oriented substantially horizontally. , Lower cable guide 30
b is shorter than the upper cable guide 30a and is directed obliquely downward.

On the other hand, a meter cable 31 connected to a rotary take-out portion (not shown) attached to the front wheel 22 is sequentially inserted through the cable guide 30b and the cable guide 30a and extends upward to be connected to a speedometer (not shown).

Then, when traveling, the meter cable 31 also moves in the vertical direction according to the vertical movement of the front wheel 22. However, in this case, since the meter cable 31 is guided by the upper and lower cable guides 30a and 30b, the meter cable 31 does not touch the left and right and is not wound around the front wheel 22 or the like.

Further, in the case where there is one cable guide, as shown by the dotted line in FIG. 2, the cater cable may largely bend below the cable guide, and it may swing to the front wheel side. This is not the case because the book cable guides 30a, 30b are provided. Moreover, since the length of the lower cable guide 30b in the direction orthogonal to the axis of the front fork 21 is shorter than that of the upper cable guide 30a,
As shown in the figure, slack tends to occur in a portion above the lower cable guide portion, and the slack portion of the meter cable hardly affects the front wheel or the like.

[Effect of device]

As described above, in the present invention, the two long and short loop-shaped cable guides are attached to the lower portion of the outer tube so that the cable guide having a long length in the direction orthogonal to the axis of the front fork is located above. Since the cables are inserted into both cable guides, the cable is guided by the two upper and lower cable guides while the vehicle is running and the suspension stroke is large. There is no such thing. Moreover, since the lower cable guide is shorter than the upper cable guide, the slack of the cable due to the vertical movement of the front wheel is largely generated in the upper cable guide portion. Therefore, this slack hardly affects the wheel or the like, and the cable can be surely protected.
