Abstract

A bicycle with upper and lower pedals and double chain driving features that the upper and lower pedals drive the bicycle with two chains, comprises a right foot pedal, a right sliding groove, a firststeel rope, a right chain, a right sprocket, a left foot pedal, a left sliding groove and a first pulley, wherein the right foot pedal is connected with the right sliding block through a right crankshaft, the right sliding block is connected with the right sliding groove through a right roller, the right sliding groove is connected with a vehicle frame through a pin, and the right roller is connected with the right sliding block through a right roller connecting shaft; The right slider is connected with the first steel rope, the first steel rope is connected with the right chain through the first pulley, and the second pulley is connected with the right chain; The right chain is connected with the right sprocket, and the right sprocket is connected with the vehicle frame through a sprocket connecting shaft; The right chain is connected with the third steel rope, the third steel rope is connected with the third pulley, the right chain is connected with the left chain through the thirdsteel rope, and the third pulley is connected with the left chain; The left chain is connected with a second steel rope through a first pulley, and the second steel rope is connected with a left slider. The invention adopts the upper and lower pedal type double chain driving, avoids the chain dropping problem caused by the chain separating from the tooth plate in riding, and has higher riding efficiency.

Description

technical field [0001] The invention belongs to the field of bicycles, and in particular relates to an upper and lower pedal type double chain drive bicycle. Background technique [0002] Today, with serious environmental pollution, bicycles, as a low-carbon and environmentally friendly means of transportation, play an irreplaceable role in the urban transportation system. For traditional chain bikes with chainrings, when the chain is severely worn or the chain lubrication is poor, it is easy for the chain to fall off the chainring during riding, causing the chain to drop. The riding efficiency is not high, and the maintenance requirements for the bicycle are relatively high. . SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide an upper and lower pedal-type double-chain driving bicycle to solve the above-mentioned problems in the background art. [0004] In order to achieve the above purpose, the present invention provides the following ...
