Abstract
The present invention relates to a gear transmission mechanism of a bicycle ridden by two persons, which is composed of a back shaft part, a back transmission shaft part, a back middle shaft part, a front transmission shaft part and a front middle shaft part. The mechanism has the advantages of simple and direct appearance, streamline box body, streamline back cover, beautiful appearance and cleanness. Besides, the driving of a faceplate by an arbitrary middle shaft is not interfered by the rotation direction of another middle shaft with randomness.
Description
Technical field:
The present invention relates to bicycle.
Technical background:
Two-person ridden bicycle is chain gear both at home and abroad.There is shortcomings such as easily taking off chain, need often lubricate, sting clothes, greasy dirt is arranged, driving efficiency is low, service life is short in chain gear.And in use two people need scrunch pedal simultaneously, do not have randomness, lack the meaning of the amusement and recreation of riding.
Summary of the invention:
The purpose of this invention is to provide a kind of gear driving mechanism for two-person ridden bicycle:
This mechanism replaces chain gear, has good cunning property (enclosed transmission), and gear-driven efficiency is higher than chain gear, and it is laborsaving to ride, long service life, and in use two people needn't scrunch pedal simultaneously, have randomness, are suitable for amusement and recreation.
The object of the present invention is achieved like this:
A kind of gear drive of two-person ridden bicycle is made up of 5 parts: backshaft skin part, rear propeller shaft part, back axis part, front propeller shaft part, preceding axis part; Axis driving pawl core drives the conical gear rotation by ratchet before it is characterized in that, drive the front propeller shaft rotation by the conical gear engagement, front propeller shaft drives the conical gear rotation of back axis part by the conical gear engagement, the conical gear of back axis part drives back axis ratchet sleeve rotation by flat key, ratchet sleeve drives the conical gear rotation of rear propeller shaft part opposite side by flat key, drive the rear propeller shaft rotation by the conical gear engagement, rear propeller shaft drives floral disc by the conical gear engagement and rotates forward; Two axis places all have ratchet core, ratchet sleeve, reach the intermittent moment at two axis places by ratchet, the effect of spring silk.
The present invention has following actively useful effect:
This gear drive is the sealing gear transmission, and the driving efficiency height has good lubricity, and long service life is three times of chain gear, and outward appearance is simple and direct, streamline casing and back cover, attractive in appearance, cleaning.And the hand of rotation of arbitrary axis is not interfered by the hand of rotation of another axis, has randomness.

IV, front propeller shaft part: mainly formed by parts such as preceding transmission tube group welding piece 22, front propeller shaft 23, bearing 24, flat key 25, conical gear 26, bearing 39, flat key 40, conical gears 41.In before bearing 24, bearing 39 are respectively charged in the stomidiums of journal box body 33 back and in the back in journal box body 16 front aperture, and before front propeller shaft 23 is supported in transmission tube group welding piece 22 holes; Conical gear 26, conical gear 41 are connected with front propeller shaft 23, and are meshed with conical gear 32, conical gear 42 respectively by flat key 25, flat key 40 respectively; Before transmission tube group welding piece 22 front ends and rear end respectively by left and right sides screw thread with preceding middle journal box body 33, afterwards in journal box body 16 be connected to a fixed.
V, preceding axis part: mainly form by parts such as preceding axis ratchet sleeve 27, preceding axis ratchet core 28, preceding axis 29, flat key 30, flat key 31, conical gear 32, preceding middle journal box body 33, locknut 35, bearing cap shim 36, bearing 37, end caps 38.Conical gear 32 connects with preceding axis ratchet sleeve 27 by flat key 31, and conical gear 26 is meshed; Ratchet sleeve 27 connects with preceding axis ratchet core 28 by ratchet, spring silk, to reach the intermittent moment of this mechanism; Bearing cap shim 36 is threaded by locknut 35 and is fixed in end cap 38 holes, bearing 37 pack in bearing cap shim 36 holes with the left side bearing preceding axis 29 is supported in before in the journal box body 33; Preceding axis ratchet core 28 is connected by flat key 30 with preceding axis 29, and end cap 38 is connected and fixed by screw 34 with preceding middle journal box body 33.
Transmission process: see from right to left, see backward in the past.
Preceding axis 29 clickwises, drive preceding axis ratchet core 28 clickwises by flat key 30, preceding axis ratchet core 28 drives ratchet sleeve 27 clickwises by ratchet, ratchet sleeve 27 drives conical gear 32 clickwises by flat key 31, and conical gear 32 drives conical gear 26 left-hand revolutions; Conical gear 26 drives front propeller shaft 23 left-hand revolutions by flat key 25, and front propeller shaft 23 drives conical gear 41 left-hand revolutions by flat key 40; Conical gear 41 drives conical gear 42 clickwises, and conical gear 42 drives ratchet sleeve 47 clickwises by flat key 43.At this moment, because ratchet, the effect of spring silk, ratchet sleeve 47 can not drive shaft gear core 20 rotations in the back, and shaft gear core 20 also can not drive 18 rotations of back axis in the back.And ratchet sleeve 47 drives conical gear 17 clickwises by flat key 21, and conical gear 17 drives conical gear 14 clickwises.In like manner, conical gear 14 drives conical gear 6 clickwises, and conical gear 6 drives conical gear 3 clickwises, and conical gear 3 links to each other by screw thread and drives floral disc 2 clickwises, and floral disc 2 links to each other by spoke and drives back circle clickwise, for moving ahead.When axis 18 clickwises of back, drive back axis ratchet core 20 clickwises by flat key 19, back axis ratchet core 20 drives ratchet sleeve 47 clickwises by ratchet, and ratchet sleeve 47 drives conical gear 17 clickwises by flat key 21.In like manner, floral disc 2 clickwises are for moving ahead.And this moment, ratchet sleeve 47 also drove conical gear 42 clickwises by flat key 43, conical gear 42 drives conical gear 41 clickwises, promptly be conical gear 26 clickwises, conical gear 26 drives conical gear 32 clickwises, and conical gear 32 drives ratchet sleeve 27 clickwises by flat key 31.Since shaft gear core 28 rotations in before ratchet, the effect of spring silk, ratchet sleeve 27 can not drive, axis 29 rotations before preceding middle shaft gear core 28 also can not drive.When floral disc 2 clickwises, promptly be conical gear 17 clickwises, that is be that back axis 18 is not driven, in like manner, preceding axis 29 is not all driven, during current axis 29 left-hand revolutions, axis ratchet core 28 left-hand revolutions before preceding axis 29 drives by flat key 30, because the effect of ratchet, spring silk mechanism, preceding axis ratchet core 28 can not drive ratchet sleeve 27 rotations, promptly are that conical gear 32 is motionless.In like manner, when after axis 18 left-hand revolutions, conical gear 17 is not driven, preceding axis 29, floral disc 2 are not all driven.
Embodiment:
See Fig. 2, figure is the double gear driving bicycle of riding.Please be simultaneously with reference to Fig. 1, preceding axis 29, back axis 18 all are connected with crank, and preceding middle journal box body 33 usefulness screws and vehicle frame are connected to a fixed, journal box body 16 and vehicle frame welding in the back.Floral disc 2 connects the back circle by spoke.Transmission process as previously mentioned, it promptly is to drive trailing wheel to move ahead that preceding Middle axle crank rotates forward, it promptly is that the driving trailing wheel moves ahead that back Middle axle crank rotates forward, and the hand of rotation of two axis does not interfere with each other.This is double when riding gear driving bicycle when carrying out, and promptly floral disc 2 rotates forward, and two axis are not all driven.
