Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a mounting structure for a Zetsuken plate mounted on a bar handle type vehicle such as a motorcycle having an inverted front fork.

[Conventional technology]

Conventional front forks used in bar-handle type vehicles such as motorcycles include an upright front fork in which an upper inner tube is telescopically inserted into an outer tube placed below, as well as a front fork in which both tubes are arranged in reverse. It has an inverted front fork.

This front fork has a pair of outer tubes fixed to both sides of both top and bottom bridges that are rotatably provided on a head pipe at the front of the vehicle body frame, and a pair of inner tubes placed below are telescopically fitted into the outer tubes. The front wheel is suspended between the lower ends of both inner tubes.

Among these types of motorcycles, motocross motorcycles have a Zetsuken plate on the front side of both the top and bottom bridges, and off-road types that can be driven on public roads have a Zetsuken plate on the front. Some vehicles are equipped with plates, and these plates are attached to both bridges with screws.In addition, in these vehicles, in order to drive on rough roads such as unpaved roads, there are stones installed at the front of the inner tube. It is equipped with a protector to prevent splashing and mud.

[Problem that the invention attempts to solve]

However, when installing the Zetsuken plate described above, it is troublesome to align the screw holes and insert the screws, and the protector moves up and down as the inner tube expands and contracts. Since there is a risk of contact with other people, improvements have been desired.

The present invention was developed against the background of the above circumstances, and aims to provide a mounting structure for the Zetsuken plate that can be easily mounted and prevents contact with the protector.

[Means for solving problems]

In order to achieve the above-mentioned object, the present invention provides a bar handle type vehicle equipped with an inverted front fork in which inner tubes located below are telescopically inserted into a pair of outer tubes fixed to both sides of a top bridge and a bottom bridge. The lower part of the number plate disposed on the front side of the vehicle body of both bridges is curved toward the outer tube side near the bottom bridge, and an insertion piece is connected to the lower part of the number plate, It is characterized in that a slit which is open at the top is formed in the lower outer tube, and an insertion piece of the number plate is inserted and supported in the slit.

[Effect]

According to the above configuration, the slit allows the positioning of the Setsuken plate, making it easy to install, and since the lower part of the Setsuken plate is formed in a curved manner near the bottom bridge toward the outer tube side, the inner Contact with the upper end of the protector due to upward movement of the plate is avoided.

〔Example〕

An embodiment in which the present invention is applied to a motocross motorcycle will be described below with reference to FIGS. 1 to 3.

The motorcycle 1 has a front wheel 6 covered by a front fender 5 suspended on the lower end of an inverted front fork 4 which is steered by a bar handle 3 at the front of a body frame 2, and a front wheel 6 covered by a front fender 5. A rear wheel 10 is suspended below the rear fender 7 provided by a swing arm 8 and a rear suspension 9.

Further, a fuel tank 11 is disposed at the upper part of the vehicle body frame 2, a seat 12 is arranged at the rear of the fuel tank 11 over the upper part of the rear fender 7, and an engine 13 is arranged in the internal space of the vehicle body frame 2 below the fuel tank 11. A radiator 14 is installed in front of the vehicle.

The inverted front fork 4 has a head pipe 20 fixed to the front part of the vehicle body frame 2, and a top bridge 21 and a bottom bridge 22, which are rotatably supported via a steering stem (not shown), and a pair of outer tubes. 23, 23 are fixed, and inner tubes 24, 24 disposed below are telescopically inserted into both tubes 23, 23, respectively.

A number plate 25 is attached to the front of both bridges 21 and 22, and a bar handle 3 is fixed to a handle holder 26 protruding from the top of the top bridge 21. The front fender 5 is sandwiched between the inner tubes 24 and 2.
At the lower end of 4, there is a disc brake 2 along with the front wheel 6.
7 is installed.

The front wheel 6 is pivotally supported by a front axle 30 that is horizontally suspended between lower brackets 28 and 29 fixed to the lower ends of the inner tubes 24 and 24. Between the front wheel 6 and one of the lower brackets 28, a disc rotor 3 that rotates integrally with the front wheel 6;
1 is disposed, and a caliper 32 for controlling the day rotor 31 is disposed at the rear of the bracket 28.
is installed.

In addition, at the front of each inner tube 24, 24,
Protectors 33, 33 protect the tube 24 and the brake hose 37, which will be described later, from flying stones and splashing mud.
are provided for each.

This protector 33 is formed by bending a vertically long plate material into a generally arcuate cross section, and has a guide holder 34 whose lower end is fixed to the front part of the lower brackets 28 and 29 and whose upper part is fitted into the outer tube 23.
The protector 33 is thereby held movable up and down as the inner tubes 24, 24 expand and contract.

A brake hose 37 is disposed between the caliper 32 and a hydraulic master cylinder 35 fixed to the bar handle 3, which supplies the pressure fluid in the hydraulic master cylinder 35 generated by gripping the brake lever 36 to the caliper 32. It is set up.

This brake hose 37 runs from the front of the brake plate 25, passes through a longitudinal groove 33a provided at the front side of the outer tube 23 on the left side of the vehicle body and the center of the inner side of the protector 33, and extends to the front part of the lower bracket 28 at the lower end. The caliper 32 is further guided rearward from the inside of the lower bracket 28.
connected to the liquid inlet.

The outer tubes 23, 23 are integrally formed with plate support parts 38, 38, respectively, which protrude toward the front side of the vehicle body at the lower part of the bottom bridge 22, and the plate support part 38 has a slit 39 that opens on the upper surface 38a. is drilled.

Further, the Zetsuken plate 25 supported by the plate support part 38 has lower pieces 25a, 25a extending to cover the front part of the bottom bridge 22.
a, 25a are respectively curved in the vicinity of the outer tube 23, and the lower part thereof is bent into a crank shape to form insertion pieces 25b, 25b at the lower end. is placed on the upper surface 38a of the plate support portion 38, and the insertion piece 25b is inserted into the slit 39.
The upper center part is screwed into the top bridge 21 with a screw 40 to attach it.

In the present invention, as shown in the above embodiment, the lower end of the number plate is temporarily fixed by the plate support member, so the number plate can be positioned, the upper part can be easily screwed, and it can be mounted with high accuracy.

In addition, even if the inner tube expands and contracts while driving and the protector moves upward, the lower piece is curved close to the outer tube to avoid contact between the upper end of the protector and the Zetsuken plate, and to prevent the protector from coming into contact with the Zetsuken plate. There will be no scratches on the Ken plate.

Incidentally, the attachment of the Zetsuken plate of the present invention can also be applied to the front plate of off-road type vehicles, etc.

[Effect of idea]

As described above, the present invention has the lower part of the Zetsuken plate arranged on the front side of the vehicle body of both the top and bottom bridges of an inverted front fork curvedly approaching the outer tube side near the bottom bridge, and an insertion piece is arranged in a row at the lower part of the Ken plate, and a slit opening at the top is formed in the outer tube at the lower part of the bottom bridge;
Since the insertion piece of the number plate is inserted and supported in the slit, the number plate can be easily positioned, the number plate can be mounted with high precision, and the installation work efficiency is improved.

In addition, when a protector is provided at the front of the inner tube, the lower part of the Setsuken plate is curved toward the outer tube to avoid contact with the upper end of the protector, which moves upward as the inner tube expands and contracts. There will be no scratches on either side of the protector.
