Rear brake treadle assembly of motorcycle

Abstract

The invention discloses a motorcycle rear braking pedal assembly. The front end of a rear braking pull rod is articulated with the upper end of a connecting plate through a pin; one end of a return spring is hitched on the pin, and the other end of the return spring is connected with a rear leg rest right support tube of a frame; a bushing is arranged in a space between the rear leg rest right support tube and a muffler; a rear braking pedal shaft is perpendicularly welded on a plate surface of the lower end of the connecting plate; the rear braking pedal shaft passes through the bushing from inside to outside, and a protruding part of the rear braking pedal shaft is sleeved with a rear braking pedal; the rear braking pedal keeps away from the muffler, and the lowest part of the rear braking pedal is not lower than the bottom surface of the muffler. The pedal assembly fundamentally overcomes the defects that a rear braking structure in the prior art is short in ground clearance, limited in regulation distance, easy to interfere with the muffler, etc., eliminates the potential safety trouble that overturn is caused by the too short ground clearance of the lowest point of the rear braking pedal in braking process, and improves the safety performance of motorcycles in running process to a great extent.

Description

technical field [0001] The invention belongs to the technical field of motorcycles, and in particular relates to a motorcycle rear brake pedal assembly. Background technique [0002] At present, the general motorcycle rear brake pedal assembly is made of components such as rear brake pull rod, fixed shaft, return spring and rear brake pedal. The fixed shaft is arranged at the bottom of the vehicle frame, the rear brake pedal passes below the muffler, and its tail is looped on the fixed shaft so that the rear brake pedal can rotate relative to the fixed shaft. The afterbody of rear brake pedal is welded with connecting plate, and this connecting plate is hinged with the front end of rear brake pull rod through pin shaft, and the rear end of rear brake pull rod is connected with rear brake rocking arm. One end of the return spring is articulated on the pin shaft connecting the rear brake pull rod and the connecting plate, and the other end is articulated on the vehicle frame....

AI Technical Summary

Problems solved by technology

Since the rear brake pedal passes under the muffler, its distance from the ground is low and the adjustment distance is limited, so it is easy to interfere with the muffler

Especially when driving on roads with poor road conditions, it is easy to cause a rollover accident due to the rear brake pedal touching the ground, which greatly affects the safe driving performance of the motorcycle

However, similar improved technologies on the market mostly use the eccentric shaft rotation structure, but the eccentric shaft is easy to interfere with other parts, and there are defects such as brake failure and laborious braking.
