Description

DETAILED DESCRIPTION OF THE INVENTION [Objective of the Invention] (Industrial Application Field) The present invention relates to a front fender device for a straddle-type four-wheeled vehicle that is integrally formed on the left and right sides.

(Prior Art) As shown in Figs. 5 and 6, a straddle-type four-wheeled vehicle is powered by a pair of left and right front wheels 1 that are steered by a bar handle 3 and an engine 4 mounted at the lower center of the vehicle body. A pair of driven left and right rear wheels 2 are arranged in the front and rear, and a rider riding on a rear upper seat 5 operates a bar handle 5 to travel.

Front wheel 1 and rear wheel 2 are front fender 6 and rear fender 7
covered with The front fender 6 and the rear fender 7 are integrated on the left and right, and the middle part is a front body cover 8,
It is formed as a rear body cover 9. An electrical component box 10 is recessed in the front upper surface of the front body cover 8, and batteries and other electrical components are centrally housed therein, and a box cover 11 is attached thereto.

Since the rod handle 3 is connected to the upper end of the steering wheel @ 12, the steering shaft 12 is arranged in a positional relationship that vertically passes through a part of the electrical component box 10, and the steering shaft is attached to the bottom of the electrical component box. A space hole will be opened for you to pass through. A brake lever, a clutch lever, a starter switch, etc. are arranged on the bar handle 3, and the brake cables, clutch cables, starter switch conductors, etc. connected thereto are routed from the center of the handle along the steering shaft 12. It hangs downward and is guided to the brake, clutch, or starter relay.

Therefore, the above-mentioned wiring and wires may pass through the electrical component box 10, and they may interfere with the electrical components and their wiring, causing trouble, and the wiring and wires themselves may turn with the steering shaft, causing the vehicle to move. When it moves with the ribs, etc., it may rub against the edge of the space hole and be damaged, which may lead to malfunction or cutting accidents.

(Problem to be Solved by the Invention) In this way, when electrical components are installed in the center of the front fender of a straddle-type four-wheeled vehicle, they interfere with the wiring and wiring that run vertically along the steering shaft. death!・There were problems in that it caused problems, and that the mating wiring and the wiring itself were easily damaged.

The present invention provides a fender device for the front 1 of a straddle-type four-wheeled vehicle, which can protect the wiring and wiring along the steering shaft from interfering with electrical components and from being damaged. The purpose is to

(Structure of the Invention) (Means for Solving the Problem) In order to achieve the above object, a front I/fender device for a straddle-type four-wheeled vehicle according to the present invention provides a front body cover portion that covers the front portion of the vehicle body below the handlebar. It is integrally formed from the front fender to the front fender that covers the left and right front wheels.
In a front fender device of a straddle-type four-wheeled vehicle in which an electrical equipment box for centrally accommodating batteries and other electrical equipment is recessed in the front upper surface of a part of the front part 1 to the body power bar, and a box cover is attached. , on the bottom of the above electrical equipment box,
A space hole is provided for the steering shaft to pass through, and a rib-like protrusion that rises from the base of an arc-shaped cross section is integrally formed on the periphery of the space hole.

(Function) With this arrangement, electrical components and their wiring are placed outside the outer periphery of the rear protrusion, and even if the cables and wiring that run along the steering shaft curve and swell, they will not be received on the inner circumferential surface of the rib-shaped protrusion. Therefore, there is no possibility that the two will interfere and cause trouble.

In addition, even if this wiring is in contact with the rib-like protrusion and turns with the rotation of the steering shaft or moves due to vibrations of the vehicle, the root of the rib-like protrusion will have an arcuate cross-sectional shape. Because of this, it is not damaged and can function stably.

(Example) DESCRIPTION OF THE PREFERRED EMBODIMENTS The drawings showing embodiments of the present invention will be explained below.

Reference numeral 21 indicates the front fender of a straddle-type four-wheeled vehicle, and left and right front fender portions 22 that cover both curved wheels.
and a front body cover part 23 connecting therebetween and covering the front part of the vehicle body are integrally formed and attached to the frame by means not shown. 24 indicates the front upper end of the frame.

A steering shaft 25 for steering the front wheels is pivotally supported on the front surface of the front upper end 24 of the frame, and an electrical component box 26 is recessed in the front body cover portion 23 in front of the steering shaft 25. Inside the electrical equipment box 26, on its bottom 26a, are a battery 27, CDI 28, starter relay 29, neutral relay 30, and reverse relay 3.
1 etc. are arranged intensively. Ignition coil 3
2. The rectifier 33 is placed in front of the front end 24 of the frame. A box cover; 34 is attached to the electrical component box 26.

A space hole 35 through which the steering shaft 25 passes is located at the rear of the bottom surface 26a of the electrical component box. The space hole 35 is formed in a semicircular shape centered on the steering shaft 25, and a rib-like projection 36 is integrally extended around the periphery of the space hole 35. As shown in FIG. 3, this protrusion 36 is set so that a base 36a rising from the bottom surface 26a of the electrical component box has an arcuate cross-sectional shape.

Furthermore, a bracket piece 37 that protrudes further upward is extended from the intrusive end of the rib-like protrusion 36, and small electric components such as the neutral relay 30, reverse relay 31, and other fuse boxes are attached to this bracket piece 37. It will be done. As shown in FIG. 4, the bracket piece 37 has a protrusion 38 formed on its upper edge to prevent handling of attached electrical components.

A mounting bracket 39 for a j-bar handle is fixed to the upper end of the steering shaft 25. Brake levers, clutch levers, starter switches, etc. are arranged on the bar handle, and the wiring and wiring 40, 41, 42 of the brake cables, clutch cables, starter switch conductors, etc. connected thereto are attached to the mounting bracket 39. From the through hole 43 along the steering shaft 25, the space hole 3
5 and is connected to a brake, clutch, starter relay 29, etc.

It is constructed as above, and the wiring and wiring are 40°41.4
If 2 is greatly curved, it comes into contact with the inner circumferential surface of the rib-like protrusion 36 and is guided or regulated to prevent further expansion. Therefore, there is no interference with electrical components or their wiring arranged outside the outer periphery of the rib-like protrusion 36, thereby preventing trouble from occurring.

As shown in FIG. 3, the contact between the wiring 40, 41, 42 and the rib-like protrusion 3G can reduce surface pressure since the base 36a has an arcuate cross section. As the steering shaft 25 rotates, the wiring 40, 41, 42 constantly swings and also moves due to vibrations of the vehicle. ! Although scratches are common, such contact will not cause damage, and malfunctions and cutting accidents can be prevented.

〔Effect of the invention〕

As mentioned above, the straddle-type four-wheeled vehicle according to the present invention has a fluorocarbon!・
The fender device has n stages of space holes through which the steering shaft passes through on the bottom of the electrical equipment box recessed in the center front of the front fender, and a rib-like protrusion that rises at the base of an arc-shaped cross section is integrally formed around the periphery. This has the effect of preventing the wiring and wiring along the steering axis from interfering with electrical components and their wiring, as well as preventing them from being damaged and leading to malfunctions, and preventing the occurrence of active and passive troubles. be.
