Abstract
A bicycle driven by a conic gear cluster is provided. On a foot middle-axle and a rear wheel axle, conic gears are mounted. A driving shaft is mounted through two bearings on a frame. At two ends of the driving shaft, conic gears are mounted, which engage with the conic gears on the middle-axle and the rear wheel axle. For adjusting speed, the driving shaft is a telescopic shaft that comprises two half axles which are shrunk-on and abut. On the middle-axle, two conic gears of different diameters are overlapped. Additionally, a shifter-fork speed regulator is formed by a shifter fork connected with the driving shaft through a pendulum shaft in a guide groove of a positioning board. Comparing with a bicycle driven by chain of prior art, the utility model is of simple structure, reliable, not liable to damage, reduces maintenance, avoids fatlute contamination of hands in repairing a dropped chain, and allows cleaner use.
Description
Technical field: this practical newline relates to a kind of unpowered vehicle, particularly bicycle.
Background technology: existing bicycle, adopt pedal and chain sprocket drive, because the easy loose or dislocation of chain of chain wheel driving mechanism.Riding often runs into and need mount chain again to sprocket wheel, causes the bicyclist to get full hand greasy dirt, very awkward, and chain is easily loosening, damages, and this is the worn-out sick of chain sprocket drive bicycle existence at present.
Summary of the invention: the objective of the invention is to design a kind of gear cluster driving bicycle, overcome above-mentioned worn-out sick that existing chain sprocket drive bicycle exists.
Technical solution of the present invention is a kind of bevel gear set driving bicycle, mainly form by saddle, vehicle frame, handlebar, front axle, the axis that connects firmly pedal, transmission device, trailing wheel, the transmission device of bicycle is that bevel gear set passes mechanism, connect via bevel gear set between the axis that connects firmly pedal and the hind axle: finishing bevel gear cuter A is housed on the axis, finishing bevel gear cuter B is housed on the hind axle; Transmission shaft two bearings of mat and bearing thereof respectively is installed on the vehicle frame, and the transmission shaft two ends are installed finishing bevel gear cuter C and D respectively; Finishing bevel gear cuter A and finishing bevel gear cuter C engagement, finishing bevel gear cuter B and finishing bevel gear cuter D engagement.
Description of drawings:
Fig. 1 is a bevel gear set driving bicycle structural representation
Fig. 2 is a bevel drive mechanism structure scheme drawing
Fig. 3 is the retractable spindle structural representation of transmission shaft
Fig. 4 is a shift fork regulating mechanism structural representation
The specific embodiment: the utility model further specifies as follows in conjunction with specific embodiments referring to accompanying drawing.
A kind of bevel gear set driving bicycle mainly is made up of saddle (1), vehicle frame (2), handlebar (3), front-wheel (4), the axis (5) that connects firmly pedal, transmission device (6), trailing wheel (7).Referring to accompanying drawing 1.The transmission device of bicycle (6) is the bevel gear set transmission device, connects via bevel gear set between the axis (5) that connects firmly pedal and the trailing wheel (7): referring to accompanying drawing 2, finishing bevel gear cuter A (8) is housed on the axis (5), finishing bevel gear cuter B (14) is installed on the hind axle (15); Transmission shaft (11) difference two bearings of mat and bearing (10) thereof, (12) are installed on the support (2), and transmission shaft (11) two ends are installed finishing bevel gear cuter C (9) and D (13) respectively; Finishing bevel gear cuter C (9) and finishing bevel gear cuter A (8) engagement, finishing bevel gear cuter D (13) finishing bevel gear cuter B (14) engagement.
In order to regulate rotating speed, concentric different finishing bevel gear cuter A (8) and the A of two diameter of closed assembly on axis
1(22) referring to accompanying drawing 2, transmission shaft (10) is made for retractable spindle: referring to accompanying drawing 3, it is that two sections semiaxis butt joints constitute, one semiaxis (16) one ends contain one section hollow tubular axis (17), hollow tubular shaft part (17) is gone up the axial rectangular through hole (18) that there is symmetry on both sides, another semiaxis (20) one ends contain one section mandrel (19), vertical pivot pin (21) is housed on the mandrel (19), mandrel section (19) is set in and constitutes two-semiaxle (16), (20) scalable butt joint in the tubular axis section (17), vertical pivot pin (21) is installed in the rectangular through hole (18), and it is spacing to slide.Also include a shift fork regulating mechanism (23) in the bicycle speed-regulating mechanism, its structure is referring to accompanying drawing 4, shift fork regulating mechanism (23) is to connect transmission shaft (11) by shift fork (24) through L shaped fork (25), L shaped fork is loaded on locating plate (26), (28) different groove (27), (29) constitute in, locating plate (26) is for being horizontally disposed with, go up tangible through hole guide groove (27), locating plate (28) is vertical the setting, on rectangular through hole guide groove (29) is arranged, locating plate (26), (28) all be fixed on the vehicle frame (2), certain point (30) is articulated on the vehicle frame (2) on shift fork (24) stage casing, fork (25) connects firmly with the outer ring of bearing (10), when moving shift fork (24) with palm, stir fork (25) along groove (27), (29) move, the finishing bevel gear cuter C (9) that drives scalable transmission shaft (11) one ends make it can be respectively with axis (5) on two finishing bevel gear cuter A (8) and A
1(22) arbitrary engagement, thus reach the purpose of regulating different rotating speeds.
The utility model has the advantages that because bicycle adopts the bevel gear mechanism driving, than the prior art chain drive, structure Simply, reliably, not fragile, reduce to safeguard, and avoided making because the maintenance chain that comes off causes full hand greasy filth to pollute With cleaner.
