Abstract

The utility model relates to a bicycle which improves a drive mechanism on the basis of the unchanged basic structure of the existing bicycle. Both sides of a medial axis are provided with big sprocket gears which replace the existing bicycle thighs. Each of the big sprocket gear is driven by the dynamic force of a vertical line segment between an upper guide wheel and a lower guide wheel of a front chain to rotate in order to drive a small sprocket gear equivalent to a big wheel disk of the existing bicycle to rotate, and drives a back wheel to rotate forward through a back chain to realize driving. A pedal driver does reciprocating motion upwards along a sliding rod, and the vertical section of the front chain is driven by a unidirectional controller always to do rectilinear motion downwards. The bicycle is characterized in that two feet of people do straight reciprocating motion in the direction of the resultant force of the gravity and the pedal force at both sides of the bicycle and do not do circle motion and arc-shaped motion; the leg part has small bending, is not easy to tire, and is capable of exerting; particularly, because a power arm is always in a maximum state and is not changed when the bicycle climbs a slope and encounters an obstacle or conducts a cycle racing, the climbing, racing and cross-country capability is enhanced, and the bicycle has labor saving and no dissipation power.

Description

Bicycle

A kind of bicycle that relates to the vehicle.

Existing bicycle has two thighs.As people by bike the time, alternately scrunch pedal with both feet, make thigh drive sprocket wheel and make circular movement around axis, sprocket wheel drives flywheel by chain and drives trailing wheel and rotate, with what realize driving.Because the bicycle of this structure is to make circular movement by both feet could realize driving, so leg curvature is big, fatiguability; In climbing or when running into obstacle, left and right thigh is being vertically to gravity direction when identical, and power arm is zero, and pedal continues to make forward that power arm changes from small to big on the gravity direction, again from large to small, is always becoming, and the forward direction effort of driving, decreases merit, waste physical efficiency.The purpose of this utility model is existing bicycle is carried out technological improvement, provides a kind of leg curvature little, and both feet are pedaled and done straight reciprocating motion, and power arm is constant forever, and cross-country, pulling force and hill climbing ability be strong, laborsaving, do not decrease merit, do not waste the bicycle of physical efficiency.
