Abstract
The invention relates to a lever bicycle, which is driven by a transmission mechanism consisting of a lever mechanism and a ratchet wheel mechanism instead of the prior transmission mode of a chain, gears and centre shafts. The lever bicycle has the advantages of obvious labor-saving effect, high riding speed, simple structure, novel and unique shape, long service life, simple process and obviously reduced production cost compared with the prior structure.
Description
Lever bicycle of the present invention belongs to machinery and bicycle designs, manufacturing technology field, is the renewal product of bicycle.
Bicycle is the widely used walking-replacing tool of wage-earners and ordinary people, and along with the flourishing and development of reform and opening-up, domestic economy, various brand bicycles all sell well, and especially younger generation follow the fashion, and constantly reject the old for the new especially.Yet settled the present, no matter which kind of brand bicycle all be unable to do without chain, sprocket wheel, caused to make complicated integral structure, and member is various, fault rate height, maintenance difficult.Chain, sprocket wheel wearing and tearing comparatively fast need frequent oiling, replacing.Need close protection to avoid greasy dirt with chain.Not fundamentally reform and innovation of standard bicycle for many years, market is very strong to the requirement that bicycle updates.
The objective of the invention is to develop a kind of bicycle laborsaving, that driving is quick, simple in structure, novelty is unique that scrunches,, promote the update of bicycle product to meet the need of market.
Technical scheme of the present invention is thoroughly to abandon chain, sprocket wheel, adopts leverage to cooperate ratchet device to form lever-ratchet interlinked mechanism and drives bicycle.Concrete measure is:
1 usefulness lever has replaced former kicking one's legs, and its lever length is 3～5 times of the former length of kicking one's legs, and the fulcrum and the rear axle of lever are hinged, and ratchet is packed on the rear wheel hub, and ratchet is hinged on the lever.Drive lever and center on axially lower swing of back when stretcher is scrunched power, ratchet then pushes away ratchet drive trailing wheel and rotates forward.
2 install spring reverse motion on the lower fork beam on the lever, its mandrel passes pressure spring, and lower fork oral area and lever are hinged, and last threaded shank is by nut, packing ring lock pressing spring.Swivel nut can be adjusted spring expansive force and control lever amplitude of fluctuation, can adjust and scrunch distance.When the stretcher power that scrunches was eliminated, under reset attachment spring expansive force effect on the lower fork beam, packing ring, nut drove mandrel, lever is upwards swung and stagnate in the extreme higher position.
3 ratchet outer covers are packed in lower fork Liang Houzhoukou place, at the inboard ratchet starting point of ratchet outer cover and the ratchet boundary baffle plate that is connected.When lever was stagnated in the extreme higher position, the ratchet that is hinged on the lever was thrown off ratchet, retreats on the washer that is fixed on the ratchet outer cover, and trailing wheel promptly is in free rotary state.
Lever-ratchet interlinked mechanism and spring reverse motion respectively are two covers, and be relatively independent, not chain mutually, is symmetrically distributed in the bicycle rear both sides.
The leverage that the present invention relates to is the single physical construction of tube, the ratchet device that relates to is that present ordinary bicycle adopts physical construction for a long time, so-called lever-the ratchet interlinked mechanism then is the combination of these two kinds of mechanisms, and the technical personnel in every machinery or bicycle designs, manufacturing field all can be understood, grasps and realize.
Compare with traditional ordinary bicycle, driving force for bicycles of the present invention greatly increases, thereby scrunches easily, and the labor-saving effect is very remarkable; Use the identical power of scrunching, road speed can increase substantially.Integral structure is simple, form member and reduce, thereby fault rate reduces, and maintenance capacity reduces, long service life; Production technology is simplified, and quality guarantees that easily integrated cost reduces.Solved and scrunched that distance can be adjusted, both feet scrunch simultaneously and hand push technical matters such as freely advance and retreat, had graceful function more.Owing to abandoned chain, sprocket wheel, and then cut axis, chain and associated member such as closed, changed former appearance, changed body frame structure for automotive on a large scale, it is moulded novel unique to make, thereby has adapted to the requirement that updates in market, by younger generation, wage-earners and ordinary people are loved.
Bicycle in China's production and marketing for many years, the supporting enterprise of each member spreads all over the world, the carrying out and implementing of national standard, each supporting enterprise product quality all can satisfy customer requirements.Practicing midwifery enterprise need only processing and manufacturing vehicle frame of the present invention, lever-ratchet interlinked mechanism and spring reverse motion, but all the other each members all external coordination solve.Therefore, fixed asset investment is few, and development and operation speed is fast.If be exactly bicycle production or the supporting enterprise product of the present invention of practicing midwifery originally, then need not to add production facilities or other fixed asset investment, economic benefit and social benefit will be very considerable all.
The invention will be further described below in conjunction with accompanying drawing.
Fig. 1 is an outward appearance sketch of the present invention.(fork guard, back shelf, front ﹠ rear mudguard and annexes such as lock, lock do not draw)
Lever when Fig. 2 is in the extreme higher position for stretcher of the present invention-ratchet interlinked mechanism view.
Lever when Fig. 3 is in extreme lower position for stretcher of the present invention-ratchet interlinked mechanism view.
In Fig. 1 and Fig. 2,1 is stretcher, and 2 is lever, and 3 is spring reverse motion, and 4 is ratchet, and 5 is catch, and 6 is ratchet.
Shown in Figure 1, when the power that scrunches on the stretcher 1 was eliminated, under the 3 medi-spring expansive force effects of reset attachment on the lower fork beam, packing ring, nut drove mandrel, lever 2 is upwards swung and stagnate in the extreme higher position.At this moment, the ratchet 4 that is hinged on the lever 2 is thrown off ratchet 6, retreats on the washer 5 that is fixed on ratchet 6 outer covers, and trailing wheel promptly is in free rotary state.
Shown in Figure 2, when stretcher 1 is scrunched power, drive lever 2 around the back axial lower swing, 4 on ratchet skids off baffle plate 5 and contacts and push away ratchet 6 drive trailing wheels with ratchet 6 and rotate forward.Nut on the rotating spring reset attachment 3 can be adjusted the amplitude of fluctuation of spring expansive force and control lever 2, can adjust and scrunch distance.
Claims (4)
1 one kinds of lever bicycles is characterized in that adopting leverage to cooperate ratchet device to form lever one ratchet interlinked mechanism and drive bicycle, have thoroughly abandoned chain, sprocket wheel, and then have cut axis, chain and associated member such as close.Its lever-ratchet interlinked mechanism type of drive is equally applicable to disabled person's three-wheel vehicle of manual tricycle, f-w-d.
