Soft bearing type folding bicycle

Abstract

The invention discloses a soft bearing type folding bicycle which comprises a front section rod frame, the front end of the front section rod frame is movably connected with the front end of a rear section rod frame, the rear portion of the rear section rod frame is connected with an end cylinder, a saddle rod is sleeved with the end cylinder and inserted into a V-shaped supporting rod, the V-shaped supporting rod is connected with the lower surface of the rear section rod frame, and the lower end of the V-shaped supporting rod is connected with a shaft cylinder; a rotating shaft is sleeved with the shaft cylinder through first bearings which are symmetrically arranged, the two ends of the rotating shaft are symmetrically sleeved with first bevel gears, the first bevel gears are meshed with second bevel gears, the front end of a transmission shaft is sleeved with the second bevel gears, and the rear end of the transmission shaft is sleeved with third bevel gears and is sleeved with anend shell through third bearings, and the third bevel gears are arranged in the end shell and engaged with fourth bevel gears; the fourth bevel gears are sleeved at the shaft end of a rear wheel, thefront end of the front section rod frame is connected with a front fork frame in a penetrating mode, and a spring is arranged at the top of the sleeve and is pressed by a nut connected with the main pipe of the front fork frame. The soft bearing type folding bicycle is compact in structure and novel and unique in thought, the traditional chain transmission is improved by changing the force transmission direction through shaft transmission gear engagement, and the bicycle frame is high in bearing capacity.

Description

technical field [0001] The invention relates to the technical field of bicycle machinery, in particular to a soft load-bearing folding bicycle. Background technique [0002] A bicycle, also known as a bicycle or bicycle, is usually a small land vehicle with two wheels. After a person rides on the car, it is powered by pedals, which is a green and environmentally friendly means of transportation. As an environmentally friendly means of transportation, it is used for transportation and travel; more and more people use bicycles as fitness equipment for cycling and exercising; bicycles themselves are also a competitive sport. [0003] Among the 25 components of a bicycle, including the frame, tires, pedals, brakes, and chains, the basic components are indispensable. Among them, the frame is the skeleton of the bicycle, which bears the greatest weight of people and goods. According to the working characteristics of each component, it can be roughly divided into guiding system,...

AI Technical Summary

Problems solved by technology

[0004] Due to the fact that the chain of the traditional chain-driven bicycle will break, the chain will fall off, etc. during the riding process, and the chain may "bite" the trousers and skirts when it meshes with the face plate, which will bring trouble and inconvenience to the riding. At the same time, when the rear wheel is loaded, its main body frame is fully rigidly connected, and the load is easy to deform. Therefore, this application discloses a shaft-driven bicycle to improve and solve the disadvantages of traditional bicycles
