Abstract
The utility model discloses a two-chain bicycle without a flywheel. The utility model relates to a tool used for riding instead of walk. The two-chain bicycle without a flywheel mainly solves the transmission form of transmission bicycles to cause the transmission bicycles to stress uniformly with labor saving for increasing speed ratio and line speed. The two-chain bicycle without a flywheel is composed of a bicycle frame, a foot pedal half shaft assembly and a ratchet transmission assembly without a flywheel. The half shaft of the two-chain bicycle without a flywheel have two R-shaped rolling groove surfaces, clockwise and anticlockwise screws are used for regulating a spring bowl and gaps among rolling balls, the ratchet shaft of the two-chain bicycle without a flywheel is provided with circular triangle R-shaped tooth grooves at equal intervals, needle rollers and the rolling balls are embedded in the grooves, and the foot pedal half shaft drives the bicycle to run by under the action of pedaling force via a left and a right chains driving the chain wheel disk of the ratchet shaft. The transmission structure of the two-chain bicycle without a flywheel has uniform stress and labor saving, and compared with traditional bicycles, the two-chain bicycle without a flywheel has high speed.
Description
The utility model relates to walking-replacing tool, specifically a kind of bicycle that does not have flywheel.
In the prior art, traditional bicycle is for there being flywheel strand bicycle, various on this basis no chain-drive bicycles are also in continuous development, it mainly is to solve laborsaving or improves speed ratio, but this class bicycle all is to carry out transmission by the version of gear mesh, its complex structure, the selection of processing and material all have is strict with, and therefore not having the chain-drive bicycle does not also enter practicality and stage of popularization at present.
The purpose of this utility model provides a kind of bicycle that does not have the flywheel duplex structure, alleviates the bicycle own wt to reach, and improves speed ratio and linear speed, makes bicycle running more laborsaving.
Realize that specific design scheme of the present utility model is, the double-stranded bicycle of this no flywheel, comprise part compositions such as vehicle frame (1), foot-operated semiaxis assembly (2), no flywheel ratchet drive assembly (5), its foot-operated semiaxis assembly (2), be divided into left and right two ends, semiaxis (E) is provided with two-sided R shape rolling groove, the gap that the bullet bowl is regulated ball (D) in the R rolling groove is regulated by positive and negative silk in two ends, to reduce semiaxis (E) axial motion and radial runout, guarantee the tram of chain sprocket (11) and chain (10).Be provided with the roll adjustment piece (21) of captive joint on the semiaxis shell, and be provided with chute (23) in the centre, it is connected with contiguous block on the following vehicle frame pipe (1), and regulates the degree of tension of chain (10) by chute (23).
No flywheel ratchet drive assembly described in the utility model, form by flower-drum (15), ratchet shaft (8), antifriction-bearing box (12), its ratchet shaft (8) is provided with equidistant circular triangle R teeth groove, teeth groove is embedded with needle roller or ball (14), and tooth dedendum is equal to or greater than needle roller or ball diameter.Ratchet shaft (8) passes flower-drum (15), the rolling gap is regulated with positive and negative silk ball end cap (13) in its two ends, simultaneously ratchet shaft (8) passes and is fixed on antifriction-bearing box (12) location of back vehicle frame on left and right, two ratchet chain sprockets (9) are separately fixed at ratchet shaft (8) two tops, connect foot-operated chain sprocket (11) and ratchet shaft chain sprocket (9) by chain (10) respectively.
The utility model is owing to foot-operated adopt the semiaxis assembly structure, and left and right foot-operated in-line, and one in front and one in back, so pedal power is even, and ratchet shaft is subjected to left and right sides chain drive simultaneously, so stress equalization and laborsaving.Its speed ratio is 1:3, and linear speed is 5655n/n.Being also advantageous in that of ratchet shaft made the double-stranded axle of passing a bridge in addition, makes the rear main wheel center shaft, makes three kinds of purposes of unidirectional flywheel-type clutch ratchet shaft.Therefore the design-calculated preceence of this drive assembly is tangible.
Further use description of drawings structure of the present utility model below.The double-stranded no flywheel of accompanying drawing 1 the utility model is the figure of speed of a motor vehicle body structure diagrammatic sketch voluntarily.Among the figure, (1) vehicle frame, (2) semiaxis assembly, (3) seat cushion, (4) frame of standing, (9) ratchet shaft chain sprocket.Accompanying drawing 2 is the utility model driving device assembly structure scheme drawings.Among the figure, (1) vehicle frame, (2) semiaxis assembly, (5) the frame regulation cock of standing, (6) sprocket pin, (7) sprocket pin binding bolt, (8) ratchet shaft, (9) ratchet shaft sprocket wheel, (10) chain, (11) ride chain sprocket, (12) antifriction-bearing box, (13) positive and negative silk bearing is regulated end cap, (14) ratchet shaft needle roller, (15) flower-drum, (16) bearing box, (17) are foot-operated, (A) axle bearing shell, (C) positive and negative silk is regulated bullet bowl, (D) ball, (E) semiaxis.Accompanying drawing 3 be flower-drum in the utility model accompanying drawing 2, ratchet shaft A-A to sectional structure chart, among the figure, (8) ratchet shaft, (15) flower-drum, (18) ratchet shaft R needle roller groove, (14) needle roller.Accompanying drawing 4 is that the utility model semiaxis assembly B-B is to sectional structure chart.Among the figure, (20) fixing piece, (21) captive joint roll adjustment piece, (22) chain tension governing screw, (23) regulating block chute transferred.
The utility model is when implementing, the bicycle axle assembly, the two-semiaxle assembly with captive joint roll adjustment piece (21) welding, fixing piece and the following vehicle frame transferred welds, and pass the regulating block chute with bolt and be fixed as one, ratchet drive assembly, two ends antifriction-bearing box are welded on the vehicle frame of back, and ratchet shaft need adopt the high material of hardness to make.
Claims (1)
- The double-stranded bicycle of a kind of no flywheel, by vehicle frame, foot-operated semiaxis assembly, no flywheel ratchet drive assemblies etc. are partly formed, and it is characterized in that foot-operated semiaxis assembly is divided into left and right two ends, and its semiaxis is provided with two-sided R shape rolling groove, the gap that the bullet bowl is regulated ball in the R rolling groove is regulated by positive and negative line in two ends, be fixedly connected with the roll adjustment piece on the semiaxis shell, and be provided with chute in the centre, it is connected with fixedly accent piece on the following vehicle frame pipe; No flywheel ratchet drive assembly, by flower-drum, ratchet shaft, antifriction-bearing box is formed, its ratchet shaft is provided with equidistant circular triangle R teeth groove, the R teeth groove is embedded with needle roller or ball, tooth dedendum is equal to or greater than needle roller or ball diameter, ratchet shaft passes flower-drum, the rolling gap is regulated with positive and negative silk ball end cap in its two ends, the antifriction-bearing box location on being fixed on about the vehicle frame of back is passed at the ratchet shaft two ends simultaneously, and two ratchet chain sprockets are separately fixed at ratchet shaft two tops, connects foot-operated chain sprocket and ratchet shaft chain sprocket by chain respectively.
