Abstract

Disclosed is an efficiency-improved bicycle with energy-accumulating and vibration-absorbing, comprising a frame. A front wheel and a handle are arranged on the frame; a central shaft, an oval main wheel disc and a footplate are arranged at the lower part of the frame. The invention is characterized in that a shaft seat and a transmission shaft are arranged at the upper rear part of the frame; an eccentric wheel and a transmission wheel are arranged on the transmission shaft; the eccentric wheel is connected with the main wheel disk by chain; a rear wheel frame is hinged with the shaft seat; a rear wheel is arranged on the rear wheel frame; a flywheel is arranged on the rear wheel; the flywheel is connected with the transmission wheel by chain; a vibration-absorbing spring is arranged between the rear wheel frame and the frame. The invention has the advantage that the up and down as well as back and forth vibration absorbing can be realized; the foot pedal vibration can be avoided when the rear wheel meets obstacle, thereby making the riding smooth and comfortable; the effective time of doing work is lengthened to increase the treading efficient; the tightness change of the chain is counteracted to make the chain in proper tense at all the time; the main wheel disk dimension is reduced to make the transmission ratio between the main wheel disk and the flywheel meet the human engineering principle, and to achieve an effortless and more comfortable treading.

Description

technical field

[0001] The invention particularly relates to a two-wheeled vehicle with energy storage, vibration reduction and efficiency enhancement. Background technique:

[0002] Bicycles and two-wheeled electric vehicles are common means of transportation for ordinary people in my country. Existing bicycle, two-wheel electric vehicle damping structure are to install damping spring on the vehicle frame, to produce damping effect. This damping structure only plays up and down damping effect to the vibration that wheel runs into convex, concave obstacle generation, can not solve the front and back vibration that two-wheeled vehicle produces when meeting convex, concave obstacle. In addition, the wheels of existing bicycles and two-wheeled electric vehicles are all circular. When the pedal arm of the bicycle is pushed to a nearly horizontal position, the pedaling torque exerted by the rider is the largest, and the work done by the applied force is the largest. The speed o...
