Abstract
The utility model belongs to a bicycle device, and particularly relates to a chainless bicycle, which overcomes the technical disadvantage of a chaindriven bicycle and provides a stable, accurate, highly efficient, portable and comfortable chainless driving structure. The driving structure of the chain-less bicycle is composed of main components, such as pedals 3, a crank 2, a centre shaft 1, a drive pulley 4, a synchronous tooth-shaped belt 5, a driven pulley 6, an overrunning clutch 17 and a rear shaft 7, wherein the crank 2 and pedals 3 are installed on the centre shaft 1, the driving pulley 4 is installed on the centre shaft 1, the driven pulley 6 is installed on the rear shaft 7 and is provided with the overrunning clutch 17 formed by engaging an inner teeth ratchet with a ratchet pawl, and the driving pulley 4 and the driven pulley 6 are connected by the synchronous tooth-shaped belt 5. The device has large transmission power, light weight, simple structure, good vibration absorption performance, small noise and easy maintenance.
Description
Affiliated technical field
The utility model belongs to bicycle device, particularly a kind of chain-less bicycle.
Background technology
At present, bicycle brings many facilities for people's life, and known bicycle transmission system is a chain-driving.But there is following shortcoming in chain-driving: transmission is not steady; Noise is arranged when riding; After severe wear and the stretching, can take off chain, phenomenon of rupture; Need time-based maintenance, lubricated; The chain cover protection need be set, for dustproof, cleaning; Complex structure, pollution clothes.
Summary of the invention
The purpose of this utility model is to overcome above technical deficiency, and a kind of steady, accurate, easy no chain-driving mode is provided.The technical scheme that its technical matters that solves the utility model adopts is: chain-less bicycle adopts the Synchronous Belt Drives system to substitute chain drive system, this driving system is with pedal, axis, driving pulley, synchronous cog belt, driven pulley, overriding clutch, rear axle is being formed of primary member, connect driving pulley by synchronous cog belt, the transmission system of driven pulley, have crank is installed on the axis, pedal, comprise by synchronous cog belt and connecting, driving pulley is installed on the axis, driven pulley is installed on the rear axle, is provided with by internal tooth ratchet and pawl ingear overriding clutch in the driven pulley of installing on the rear axle.
The beneficial effects of the utility model, compare with the chain-driving bicycle and to have: the power of transmission is big, accurately, steadily; The intensity height; In light weight; Simple in structure; Good shock-absorbing characteristic is arranged, and noise is little, and is non-slip; Wear-resistant, the life-span is long; Excellent oil resistant, low temperature resistant, heat-resisting, ageing-resistant characteristic are arranged; Be easy to maintenance; Cleaning, attractive in appearance, efficient, light, comfortable.
Description of drawings
Fig. 1 is integral structure figure of the present utility model.
Fig. 2 is the Synchronous Belt Drives schematic diagram.
Fig. 3 is the A-A section-drawing of Fig. 2.
Among the figure: 1. axis, 2. crank, 3. pedal, 4. driving pulley, 5. synchronous cog belt, 6. driven pulley, 7. rear axle, 8. spoke, 9. bolt, 10. rim, 11. cover tires, 12. saddles, 13. vehicle frames, 14. handlebars, 15. front forks, 16. front axles, 17. overriding clutchs
The specific embodiment
In Fig. 1, scrunching power is applied on the pedal (3), pass to driving pulley (4) by crank (2) and axis (1), driving pulley (4) drives driven pulley (6) by synchronous cog belt (5), driven pulley (6) drives rear axle (7), trailing wheel rotation by overriding clutch (17), realizes travelling forward of bicycle then.
In design, synchronous cog belt can be selected polyamine fat or rubber thermoplastic material for use, and belt wheel is selected non-metallic material, metallic material or composite material for use, transmitting ratio 2-4, the number of teeth 30-80 of driving pulley (4), the number of teeth 16-20 of driven pulley (6).
