Foot brake structure for minisize motorcycle

Abstract

The invention provides a foot brake structure of a small motorcycle vehicle, which can realize the miniaturization of the foot brake structure, increase the degree of freedom in design, and reduce processing hours and costs. In the foot brake structure of this small motorcycle vehicle, a pair of left and right pedals (31) supported by the main frame (18) are arranged between the handlebar and the front and rear double seats, and the brakes for the rear wheels that brake the rear wheels are operated. The brake pedal (33) of the device can be rotatably installed on the main frame (18), and the pedal part (33b) of the brake pedal (33) protrudes from the pedal (31) and is configured. The pedal (31) constitutes the vehicle frame The support plate (81) of a part of (11) is supported, and the fulcrum (34) of pedal (33) is provided with on the support plate (81), and this fulcrum (34) is configured on the main frame 18 from the side. above and below the pedal (31).

Description

technical field [0001] The invention relates to an improvement in the structure of a foot brake of a small motorcycle vehicle. Background technique [0002] As a conventional foot brake structure for a scooter, there is known a structure in which a rear wheel brake is operated by operating a foot brake pedal protruding above the pedal (for example, refer to Patent Document 1). [0003] Patent Document 1: (Japanese) Patent No. 3447470 [0004] FIG. 1 , FIG. 3 , and FIG. 4 of Patent Document 1 will be described below. [0005] The main pipe 3 is disposed below the footboard Ps of the scooter so as to extend in the front-rear direction of the vehicle, and a cylindrical shaft guide 8 is attached to the main pipe 3 through the main pipe 3 in the vehicle width direction. The brake shaft 9 Rotatably inserted into the shaft guide 8, a foot brake pedal BP is installed at one end of the brake shaft 9, and a relay rod 11 is installed at the other end of the brake shaft 9, and the rel...

AI Technical Summary

Problems solved by technology

[0007] When the distance between the brake shaft 9 and the foot pedal Ps is large, the distance between the brake shaft 9 and the tread surface f becomes longer. As a result, the foot brake pedal BP becomes large, and the structure supporting the foot brake pedal BP also becomes large. , resulting in increased weight and occupying a larger space

In addition, when the shaft guide 8 is attached to the large-diameter, thick-walled main pipe 3, processing is very difficult, so the degree of freedom in design is reduced, and processing man-hours and costs are increased.
