Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a brake pedal for a motorcycle.

0002

[Prior Art] In a motorcycle, a shaft hole provided at the base of a brake pedal is rotatably attached to a bracket attached to the lower side of the frame using a support shaft. Using the tip of your toe, you press down on the tip of the brake pedal to rotate the brake pedal and operate the brakes on the rear wheels. A hook plate is fastened with bolts or a pin is planted on the brake pedal, and one end of the return spring is hooked to the hook plate or pin so that the brake pedal returns to the specified position by the elasticity of the return spring. I have to. Further, one end of the spring of the stop lamp switch is hooked to the hook plate or pin, and when the brake pedal is depressed, the stop lamp switch is connected and the stop lamp at the rear of the vehicle body is turned on. For example, JP-A-61-1603
See Publication No. 82.

[Problems to be Solved by the Invention] Brake pedals are made of steel by forging, etc., and in addition to drilling a shaft hole at the base by cutting, a screw hole or press-fit hole is required to attach the hook plate or pin. It is necessary to process the part. Further, a grease injection hole is formed in the shaft hole so that lubricating grease can be injected therein, and a grease nipple or plug bolt is screwed into the entrance of the grease injection hole. As described above, there are disadvantages in that there are many parts to be machined, parts to be attached are required, the number of processing steps and assembly steps are large, and the cost is high.

[0004] In view of the above, the present invention provides a hook plate that is fastened to the grease injection hole provided in the shaft hole of the brake pedal so that the return spring and the spring of the stop lamp switch can be latched. The objective is to obtain a brake pedal for a motorcycle that requires fewer assembly parts and can reduce costs.

[0005]

[Means for Solving the Problems] In order to achieve the above object, the brake pedal of the motorcycle of the present invention has a shaft hole provided at the base of the brake pedal that is rotatably mounted to a bracket of the frame by a support shaft. Then, provide a grease injection hole in the shaft hole, pass the hook plate through the grease nipple or plug bolt that is screwed into the entrance of the grease injection hole, and tighten it together.Hang one end of the return spring and the stop lamp switch spring on the hook plate. The reason is that I tried to stop it.

[0006]

[Operation] When you press down on the tip of the brake pedal, the brakes on the rear wheel are activated via the brake rod, allowing you to brake. The spring for the stop lamp switch is also pulled at the same time, connecting the stop lamp switch and lighting the stop lamp installed at the rear of the vehicle. When you stop pressing down on the brake pedal, the return spring returns it to its original position. The shaft hole of the brake pedal is lubricated with grease injected from the grease injection hole. The hook plate that holds one end of the return spring and stop lamp switch spring can be fastened with a grease nipple or plug bolt that is fastened to the entrance of the grease injection hole, so there is no need to use a screw hole or pin to attach the hook plate. , the structure can be simplified.

[0007]

Embodiments Hereinafter, embodiments of the present invention will be explained with reference to FIGS. 1 to 5. The brake pedal 1 is formed from a steel material by forging or the like, and has a shaft hole 2 bored in its base. The brake pedal 1 is rotatably attached to a bracket 4 attached to the lower side surface of the frame 3 by a support shaft 5. A brake rod 7 is connected to an arm 6 at the base end of the brake pedal 1, and is connected to a master cylinder 8 of a rear wheel brake. A grease injection hole 9 is bored in the brake pedal 1 so as to communicate with the shaft hole 2 from the outside. Grease is injected into the grease injection hole 9, and a grease nipple 10 or plug bolt 11 is screwed into the inlet. And hook plate 12
A grease nipple 10 or plug bolt 11 is passed through the hole provided in the hole, and the hook plate 12 is fastened to the brake pedal 1 with the grease nipple 10 or plug bolt 11. One end of the return spring 13 is hooked to the hook plate 12, and the spring 1 of the stop lamp switch 14 is hooked to the hook plate 12.
Hook one end of 5.

A grease nipple 10 is screwed onto the entrance of the grease injection hole 9 which communicates with the shaft hole 2 of the brake pedal 1.
Alternatively, since the hook plate 12 that hooks the return spring 13 and the spring 15 of the stop lamp switch 14 can be fastened with the stopper bolt 11, a screw hole for attaching the hook plate 12 to the brake pedal 1 is not required, and the number of machining steps can be reduced. Also, there is no need for special bolts for fastening the hook plate 12, reducing the number of parts and the number of assembly steps.

[0009]

As explained above, since the present invention is constructed as described above, the return spring and the stop lamp switch can be controlled by the grease nipple or plug bolt installed at the entrance of the grease injection hole leading to the shaft hole of the brake pedal. Since a hook plate for hooking the spring can be attached, there is no need for special screw holes or bolts for attaching the hook plate, and the number of processing and assembly steps can be reduced, leading to cost reductions. or,
Maintenance is also improved because there are fewer parts.
