Laborsaving bicycle utilizing rider dead weight

Abstract

The invention relates to a laborsaving bicycle utilizing a rider dead weight. The laborsaving bicycle comprises a bicycle and is characterized in that a gear box is mounted at the back part of the bicycle; an output shaft of the gear box is connected with a back wheel; a pair of pedals are arranged on the left and right sides of the bicycle; each pedal is connected to an input shaft of the gear box via a long arm; the tail end of the long arm is connected with the input shaft via a unidirectional ratchet; a return spring is connected to the long arm; the left and right long arms are connected with each other via a connection belt; the connection belt is wound on a pulley; the output shaft of the gear box is in a connection with a back wheel shaft via a unidirectional ratchet; the output shaft of the gear box is connected with a gear on a back wheel loop via a unidirectional ratchet. The laborsaving bicycle utilizing rider dead weight has the advantages that the bicycle is driven to advance forward by utilizing the rider dead weight, and labor-consuming leg pedaling is avoided.

Description

technical field [0001] The invention relates to a bicycle, in particular to an energy-saving bicycle utilizing the rider's own weight. Background technique [0002] At present, as the global energy shortage and emissions intensify, and the environment deteriorates, more and more people feel the importance of energy conservation and emission reduction, but if people drive less, what means of transportation should be used instead? Especially in cities, many people commute to and from get off work relatively short distances. If they can replace cars with bicycles, it can greatly reduce the pressure on urban roads, reduce consumption and reduce emissions. However, the existing bicycles mainly rely on people's legs to drive the bicycle forward, and in a circle of the pedals, only a quarter of the fan is exerted by the legs, and the rest are useless. , so it is very difficult to ride, and the distance is a little longer, such as more than 5 kilometers, people may not be able to be...
