II transmission shaft part: mainly formed by forward flange end cap 12, transmission shaft 13, transmission tube 14, bearing 15, conical gear 17, flat key 31, rear flange end cap 32, bearing 33, flat key 34, conical gear 35.Bearing 15 is packed in rear flange end cap 32 holes, and with bearing 33 in the casing 45 back stomidiums of packing into transmission shaft 13 is supported in transmission tube 14 holes; Conical gear 35, conical gear 17 link with transmission shaft 13, and are meshed with conical gear 36, conical gear 22 respectively by flat key 34, flat key 31 respectively; Forward flange end cap 12, rear flange end cap 32 are connected to a fixed with casing 45 rear ends, back cover 16 respectively by screw 11; Transmission tube 14 is connected with forward flange end cap 12, rear flange end cap 32 respectively by left and right sides screw thread.
The III hind axle part: mainly be made up of parts such as rear axle 18, bearing 19, locknut 20, sediment barrier 21, conical gear 22, ratchet core 23, floral disc 24, bearings 25, ratchet core 23 is fixing by being threaded with floral disc 24; Conical gear 22 connects by ratchet, spring silk with ratchet core 23, to reach the intermittent moment of this mechanism.Sediment barrier 21 plays a supportive role to conical gear 22 by steel ball, and sediment barrier 21 is regulated locking by 2 locknuts 20; The bearing 19 of packing in the ratchet in-core hole is supported in rear axle 18 in floral disc 24 holes with bearing 25 in the floral disc 24 left end holes of packing into.Back cover 16 covers in above parts wherein, and is connected and fixed with rear flange end cap 32.
Transmission process: in the past backward, see from right to left.
When axis 3 clickwises, gear 46 drives clickwise by axis 3 splines, and gear 46 is by flat key 44 driven gears 47 clickwises, and gear wheel shaft 7 is meshed by rotating counterclockwise with gear 47.Gear wheel shaft 7 drives conical gear 36 by flat key 39 and rotates counterclockwise.Conical gear 36 drives conical gear 35 clickwises, and conical gear 35 drives transmission shaft 13 clickwises by flat key 34, and transmission shaft 13 drives conical gear 17 clickwises by flat key 31, and conical gear 17 drives conical gear 22 clickwises.Conical gear 22 drives ratchet core 23 clickwises by ratchet, and ratchet core 23 drives floral disc 24 clickwises by being threaded.Otherwise, when axis 3 left-hand revolutions, conical gear 22 left-hand revolutions as can be known, because ratchet, the effect of spring silk, ratchet core 23 is not driven, floral disc 24 is also motionless.When floral disc 24 clickwises, floral disc 24 drives ratchet core 23 clickwises by being threaded, and owing to ratchet, the effect of spring silk, conical gear 22 is not driven, and axis 3 is also motionless.
Speed change transmission: be rotatably installed in the rot in the bicycle handle bar, drive steel rope 28 motions, outlet seat 29, outlet seat 30 and guide roller 27, offside guide roller by I casing part drive shift fork 2 and move reciprocatingly at declutch shift shaft 1, shift fork 2 also driven gear 46, gear 47, gear 48 along moving reciprocatingly on the spline of axis 3, make gear 46 and gear 42, gear 47 and gear wheel shaft 7, gear 48 and gear 40 correct engagement, reach 1: 2.05,1: 2.9,1: 1.75 middle and high, low transmitting ratio.
Sum up: the conical gear 17,22,35,36 of this mechanism all adopts top system receipts tooth system helical tooths such as Jackie Gleason, its stable drive, noiselessness, tooth root intensity height, long service life; The II of this mechanism transmission shaft partly adopts the flange type of attachment, has to be connected firmly, and gear accuracy of positioning height, service life of gear is long, advantages such as convenient disassembly; This mechanism is the enclosed transmission, and lubricated good, driving efficiency is up to 98%, and be three times of chain gear service life; Casing and back cover are the streamline moulding, simple and direct, attractive in appearance, the cleaning of outward appearance.
Five. embodiment: see accompanying drawing 2, figure is that flange join type gear-driving speed-variable bicycle (with reference to accompanying drawing 1) axis 3 is connected with crank.Casing 45 and vehicle frame welding.Floral disc 24 connects trailing wheel by spoke.Transmission process scrunches pedal forward as previously mentioned, drives crank, axis rotation, promptly is that trailing wheel moves ahead; The tap pedal of kicking backward drive crank, axis rotation, and trailing wheel is motionless; When carrying out, promptly floral disc 24 rotates forward, and Middle axle crank is not driven.Speed-change process by handle pulling steel rope crank motion, makes gear 46 and gear 42 as previously mentioned, gear 47 and gear wheel shaft 7, and gear 48 and gear 40 correct engagement make this car obtain middle and high, low transmission speed ratio.
