Abstract
A kind of bicycle drive, this device have a transmission gearbox that is linked together with vehicle frame, are provided with crank-swinging mechanism, overriding clutch in transmission gearbox---gear type one-way driving mechanism or ratchet---gear type one-way driving mechanism and speed-changing mechanism.Transmission gearbox is to having adopted transmission shaft mechanism between the drive wheel.
Adopt bicycle of the present invention, the crank reciprocally swinging, variable-ratio is without chain, than ordinary bicycle riding speed height, laborsaving, safe, comfortable.
Description
Before the present invention, drive the driving device of bicycle, record to some extent in patent documentations such as GB2086320A and GB2127111 by the pedal crank motion.
The mechanism structure of being put down in writing in bicycle drive of the present invention and the above-mentioned patent documentation is inequality.More than the body function of recording and narrating in the above-mentioned patent documentation, profile is just clean, flexible arrangement, can be arranged on the diverse location of vehicle frame, and can be widely used in mechanically by manually driven.
Main points of the present invention are, have adopted a transmission gearbox that is connected on the vehicle frame.The crank-swinging mechanism that in transmission gearbox, forms by the garden finishing bevel gear cuter that is meshed by three, overriding clutch-gear type one-way driving mechanism that the garden stud wheel that is meshed with two pairs by two overriding clutchs is formed, the ratchet-gear type one-way driving mechanism that perhaps adopts the garden stud wheel that is meshed with two pairs by two ratchets to form.Adopt a pair of garden bevel drive at the transmission gearbox mouth, the bicycle drive wheel adopts a pair of garden bevel drive, in the middle of two pairs of garden finishing bevel gear cuters, by the driven off by shaft transmission shaft of a transmission mechanism.In transmission gearbox, speed-changing mechanism can also be set.The box speed-changing mechanism of various structures can be applied in the transmission gearbox, still can adopt chain-driving between transmission gearbox mouth and drive wheel.
Crank-swinging mechanism in the transmission gearbox mainly is made of three garden finishing bevel gear cuters that are meshed.Two non-conterminous garden finishing bevel gear cuters are linked together with the axle that crank is housed respectively.When certain crank during, by the garden bevel drive, another crank is swung in the opposite direction, and realized the action of crank reciprocally swinging to the swing of direction.
Overriding clutch-gear type one-way driving mechanism in the transmission gearbox mainly is made of the garden stud wheel that two overriding clutchs are meshed with two pairs.The interior ring of two overriding clutchs is linked together with the axle that crank is housed respectively.The gear ring outer shroud of overriding clutch is the gear ring of a garden stud wheel.The gear ring outer shroud of two overriding clutchs, be meshed with two garden stud wheels respectively, when certain crank during, drives an equidirectional rotation of overriding clutch that is linked together with this crank, the garden stud wheel rotation that the gear ring outer shroud drive of overriding clutch is meshed with it to the swing of direction.By crank-swinging mechanism, another crank is swung in the opposite direction, with the overriding clutch idle running that this crank is linked together, realize that folk prescription is to transmitting movement.
In ratchet-gear type one-way driving mechanism in the transmission gearbox, be that the overriding clutch in overriding clutch-gear type one-way driving mechanism is changed into ratchet.The ratchet outer shroud also is the gear ring outer shroud, and other structure is identical.
The embodiment indicated below in conjunction with accompanying drawing is described in further detail the present invention.
Figure one is an outside drawing of using first embodiment of the present invention.Transmission gearbox b and vehicle frame a are linked together.When crank C reciprocally swinging, give drive wheel Motion Transmission by the d of transmission shaft mechanism again by the crank-swinging mechanism in the transmission gearbox b, overriding clutch-gear type one-way driving mechanism or ratchet-gear type one-way driving mechanism, speed-changing mechanism.
Figure two is driving device kinematic sketch of mechanisms of first embodiment of the invention.Figure three, figure four are driving device expansion drawings of first embodiment of the invention.
In three garden finishing bevel gear cuters that are meshed 10,11,14, garden finishing bevel gear cuter 10 is connected on the crank shaft 5, and garden finishing bevel gear cuter 14 is connected on the crank shaft 19.When crank 6 during, crank 18 is swung in the opposite direction by garden finishing bevel gear cuter 10,11,14 to the swing of a certain direction.Two crank shafts 5,19 are bearing in respectively on the bearing that is installed in casing 12 and bearing brackett 13.Gear 11 is installed on the bearing of bearing brackett 13.Bearing brackett is connected on the casing 12.
The rotation of axle 3 is passed to axle 1 to motion by variable gear 2.Garden finishing bevel gear cuter 21 is linked together with axle 1, and garden finishing bevel gear cuter 22 is bearing on the bearing of casing 12 and is meshed with garden finishing bevel gear cuter 21.Garden finishing bevel gear cuter 30 is connected on the live axle skin 33, and garden finishing bevel gear cuter 28 is bearing on the gear stand 29 and is meshed with garden finishing bevel gear cuter 30.Plunging joint 23,27 and 24,26 is linked together with garden finishing bevel gear cuter 22,28 and transmission shaft 25 respectively.Gear stand 29 and axletree 32 are connected on the vehicle frame 31.The rotation of transmission gearbox axis 1 passes to drive wheel by above-mentioned transmission shaft mechanism, drives cycle racing.
Figure four is outside drawings of using second embodiment of the present invention.Transmission gearbox b and vehicle frame a are linked together.When crank C reciprocally swinging,,, give drive wheel Motion Transmission by chain-driving d and e again motion output transmission gearbox by the crank-swinging mechanism in the transmission gearbox b, overriding clutch-gear type one-way driving mechanism or ratchet-gear type one-way driving mechanism.F is a seat, and g is a backrest.
Figure six is driving device kinematic sketch of mechanisms of second embodiment of the invention.Figure seven is driving device expansion drawings of second embodiment of the invention.
In three garden finishing bevel gear cuters that are meshed 4,5,6, garden finishing bevel gear cuter the 4, the 6th lumps together into positive body structure with loops in crank shaft, the overriding clutch.When crank 1 during, crank 9 is swung in the opposite direction by garden finishing bevel gear cuter 4,5,6 to the swing of a certain direction.Two garden finishing bevel gear cuters 4,6 are bearing in respectively on the bearing brackett of casing 15 and vehicle frame 12.
The gear ring outer shroud 3,7 of overriding clutch is meshed with garden stud wheel 13,11 respectively. Garden stud wheel 13,11 14 combines into positive body structure with axle, when crank 1 during to a certain direction swing, drives the gear ring outer shroud 3 equidirectional rotations of overriding clutchs by rolling body 2.The garden stud wheel that is meshed with gear ring outer shroud 3 drives axle 14 and rotates in the opposite direction.Turn to identical with garden stud wheel 11 mating teeth circle outer shrouds 7 with garden finishing bevel gear cuter 4.Make the overriding clutch idle running that is bound up with garden finishing bevel gear cuter 6 by rolling body 8, realize that folk prescription is to transmitting movement.Sprocket wheel 10 is connected on the axle 14, makes the Motion Transmission in the transmission gearbox give drive wheel by chain-driving, and drives cycle racing.
Figure eight is axial view of overriding clutch among the present invention.The 7th, ring in the overriding clutch, the 8th, rolling body, the 9th, overriding clutch gear ring outer shroud.
Figure nine is axial view of ratchet among the present invention.The 1st, ratchet gear ring outer shroud, the 2nd, ring in the ratchet, the 3rd, ratchet.
