Abstract

PURPOSE:To provide a motorcycle rear wheel rim mud removing device which can prevent mud from accumulating by fitting spatula pieces to the inside surfaces of the right and left forks of a rear fork suspending a rear wheel, arranging the tips of spatula pieces in adjacency to the rim peripheral surface of the rear wheel, and scraping off mud accumulated on the peripheral surfaces of the rim with spatula pieces through the rotation of the rear wheel. CONSTITUTION:Spatula pieces 14 whose tips are made upward, are fitted in tightness and so as to be position-adjustable longitudinally, to the inside surfaces of the right and left forks 5 of a rear fork 1 for fitting rotatably a rear wheel 6 at the rear end by means of a rear axle, and the tips of spatula pieces 14 are arranged in adjacency to the peripheral surfaces of the rim 8 of the rear wheel 6.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a motorcycle rear wheel rim mud dropping device.

[0002]

2. Description of the Related Art Some motorcycles, which are called motocross type motorcycles, mainly run on an off-road with a bad road surface. This kind of motorcycle sometimes runs in a mud, etc., and in this kind of place, the mud jumped up by the front wheels is scattered backwards, and the mud accumulates on the peripheral surface of the rim of the rear wheels.

[0003]

When mud accumulates on the rim of the rear wheel, the weight of the rear wheel becomes heavy, and the unsprung weight of the cushion that suspends the rear wheel increases, so that steering stability deteriorates. However, there is an inconvenience that the rider's fatigue increases. or,
As the weight of the rear wheels increases, the braking performance of the rear wheels also deteriorates.

In view of such a point, the present invention has a spatula piece attached to the inner side surfaces of the left and right forks of the rear fork on which the rear wheel is suspended, and the tip of the spatula piece is disposed close to the peripheral surface of the rim of the rear wheel. An object of the present invention is to obtain a rear wheel rim mud removing device for a motorcycle that can scrape mud accumulated on the peripheral surface of the rim by rotation of a rear wheel with a spatula piece so as to prevent the mud from accumulating.

[0005]

In order to achieve the above object, a rear wheel rim mud dropping device of a motorcycle according to the present invention includes a left and a right hawk of a rear hawk having a rear axle rotatably attached to a rear end thereof. The spatula piece with the tip facing upward on the side face is tightened so that the position of the spatula piece can be adjusted forward and backward, and the tip of the spatula piece is arranged close to the peripheral surface of the rear wheel rim.

[0006]

[Function] When the rear wheel rotates, the mud that adheres to the peripheral surface of the rim is scraped off by the spatula piece, so that it is possible to prevent the mud from accumulating on the peripheral surface of the rim, and the rear wheel retains the mud. It is possible to prevent the product from becoming heavier. Also, the rear wheels adjust the tension of the driven chain by moving the rear axle to the rear side. Then, according to the chain adjustment, the spatula piece is also moved to the rear side and fastened to prevent it from hitting the rim.

[0007]

Embodiments of the present invention will be described below with reference to FIGS. The rear hawk 1 has its front end pivotally attached to the frame 2, and the lower ends of the cushion units 4 are connected to each other via the links 3. Both ends of the axle 7 are fastened. The rear wheel 6 has a tire 9 fitted on the outer periphery of the rim 8. Also, the sprocket 11 and the rear wheel 6 of the engine 10
Engine 1 with the chain 13 wrapped around the sprocket 12
The rear wheel 6 is driven at 0.

Then, spatula pieces 14 with their tips facing upward are fastened to the inner surfaces of the left and right forks 5 of the rear fork 1. The spatula piece 14 is provided with front and rear long holes 15, and the tip of the spatula piece 14 is adjusted so as to be close to the peripheral surface of the rim 8.

When the rear wheel 6 rotates, the mud adhering to the peripheral surface of the rim 8 can be scraped off by the spatula piece 14, and the mud can be prevented from accumulating on the rim 8. When the tension of the chain 13 is adjusted by moving the rear axle 7 back and forth, the fastening position of the spatula piece 14 is adjusted back and forth accordingly. The spatula piece may be formed by using a synthetic resin or a light alloy. Further, the spatula piece may be set as an optional part for lace or the like.

As described above, since the present invention is configured as described above, the mud adhering to the peripheral surface of the rim can be scraped off with a spatula piece by the rotation of the rear wheel, and the mud can be adhered to the peripheral surface of the rim. Can be prevented from accumulating. As a result, it is possible to prevent the weight of the rear wheels from increasing due to mud, maintain good steering stability, and reduce rider fatigue.
