Abstract

The utility model discloses a semiautomatic single-chord boosting bicycle. The bicycle is characterized in that a chord-force spring case arranged on a bicycle frame, a spring box arranged in a gear case, and a drive back stop gear share the same shaft; the shaft is hollow and is movably sheathed on a chording wheel shaft; a chording back stop gear is arranged on the chording wheel shaft, and the chording back stop gear and the drive back stop gear are matched with a power device, a driving device, a speed changing device, a gearing device, a chording device and a braking device. The bicycle can alternately match and use chord force and manpower to replace single manpower for ridding according to actual need and has the advantages of easiness and comfort, time saving, labor saving, quickness and convenience.

Description

S. A. monochord morpet

The utility model relates to technical field of bicycles, specifically adds a little parts on existing bicycle, with reach laborsaving, power-assisted, fast, voluntarily purpose.

Except the existing bicycle, fuel oil, combustion gas, electric car, no matter which kind of specification, model strictly speaking, all can not be bicycle, can only be bicycle, rickshaw, effort, time-consuming, speed is slow.

The purpose of this utility model is to provide a kind of bicycle, and it can be according to actual needs, and string power is that spring force, manpower alternately are used, and replaces simple manpower and rides.

The technical solution of the utility model is achieved in that S. A. monochord morpet, and it mainly comprises compositions such as engine installation, driving device and speed change with matching, brake, string holder, vehicle frame, tire, it is characterized in that:

A. clockwork spring case, gear case and vehicle frame are fixed;

B. string power clockwork spring will place in the going barrel, and two is affixed with going barrel, the wheel shaft that winds up respectively, and it is affixed with the check gear that winds up that the wheel shaft that winds up passes main brass;

C. brake disc or slice, thin piece are fixed on the going barrel, and going barrel, active check gear and main brass are affixed, initiatively check gear and variable gear engagement;

D. the wheel shaft that winds up is fixed with clockwork spring case, gear case respectively by bearing;

E. variable gear, transmission gear and transmission shaft are affixed, transmission shaft and the socket of countershaft cover;

F. mesomerism gear and countershaft the cover affixed and with the check gear mesh that winds up;

J. shifting gear only with move, can not rotation and loose joint on driven shaft, be equipped with in the preceding driven gear and fly son, the back driven gear is affixed with driven shaft, and by chain or transmission shaft respectively with the flower tooth, fly the tooth biography and connect.

The utility model adopts on the basis of the bicycle of original each model, install an accessory equipment additional, do not change primary car structure, do not change the former custom of riding, by engine installation, driving device and speed change with matching, brake, string holder, can be according to actual needs, string power, manpower alternately are used, replace simple manpower and ride free and relaxed, time saving and energy saving, rapid and convenient.

Fig. 1 is a structural representation of the present utility model.

The utility model will be further described below in conjunction with drawings and Examples.

The utility model installs an accessory equipment additional on the basis of existing bicycle, be specially: clockwork spring case 25, gear case 24 fix with vehicle frame, string power clockwork spring 2 places in the going barrel 3, two is affixed with wind up wheel shaft 8 and going barrel 3 respectively, brake disc or slice, thin piece 4 are fixed on the going barrel 3, going barrel 3, active check gear are that ratchet 7 is fixed in respectively on the main brass 5, and main brass 5 is fixed in the joint portion of clockwork spring case 25 and gear case 24 by bearing 6.The check gear that winds up is that ratchet 9 is affixed with the wheel shaft 8 that winds up, and wheel shaft 8 two of winding up are fixed on the tank wall of clockwork spring case 25 and gear case 24 by bearing 1 and bearing 10 respectively.Variable gear 14, transmission gear 16 is affixed with transmission shaft 13, and 13 1 of transmission shafts are fixing with gear case 24 by bearing 12, and one is overlapped 19 sockets with countershaft, and countershaft cover 19 is affixed with mesomerism gear 18, and fixing with gear case 24 by bearing 11.Variable gear 14 and initiatively check gear 7 engagements, the mesomerism gear 18 and check gear 9 engagements of winding up.Shifting gear 17 and driven shaft 15 loose joints, driven shaft 15 by bearing fixing on gear case, preceding driven gear 21 be equipped with fly son at interior, back driven gear 22 and driven shaft 15 affixed and by preceding chain or transmission shaft 20, rear chain or transmission shaft 23 respectively with flower tooth 26 and fly tooth 27 and pass and connect.28 is tire among the figure.

The utility model installs, check errorless, foot-operated earlier riding, pin brake facing 4, stir shifting gear 17 and mesomerism gear 18 engagements, pedal drives flower tooth 26, preceding chain 20 is made left-hand revolution, driven gear 21 was made rotation in the same way, back driven gear 22 before preceding chain 20 drove, shifting gear 17 is coaxial with preceding driven gear 21, so do to rotate in the same way with speed, back driven gear 22 by rear chain 23 with fly tooth and pass and connect, fly the tooth rotation, drive wheel and advance, simultaneously, shelves are lived gear 17 and mesomerism gear 18 engagements, the mesomerism gear 18 and check gear 9 engagements of winding up, the check gear 9 that winds up is affixed with the wheel shaft 8 that winds up, so the wheel shaft 8 that winds up is made left-hand revolution, because of an end of clockwork spring 2 affixed with the wheel shaft 8 that winds up, so clockwork spring 2 tightens.Treat clockwork spring 2 epipodiums, stir shifting gear 17 and transmission gear 16 engagements, releasing of brake sheet 4, going barrel 3 rotations, because of active check gear 7 coaxial with going barrel 3, so initiatively check gear 7 is done to rotate in the same way with speed, variable gear 14 meshes with active check gear 7 again, so variable gear 14 is made cw and is quickened rotation, because of transmission gear 16 coaxial with variable gear 14, so transmission gear 16 is done to rotate in the same way with speed, this moment, shifting gear 17 meshed with transmission gear 16, so shifting gear 17 is made conter clockwise with the speed rotation, because final drive gear 22 is coaxial with shifting gear 17, so back driven gear 22 is done to rotate in the same way with speed, and drive by rear chain 23 and to fly tooth 27, fly tooth 27 and drive wheel revolutionss.Fly son because of being equipped with in the preceding driven gear 21, so, can step reinforcing or transfixion arbitrarily.

Pin brake disc or slice, thin piece 4, car is a stagnation of movement, opens brake disc or slice, thin piece 4, and car promptly moves ahead.As not needing power-assisted or acceleration, shifting gear 17 can be dialled in Neutral Position, bicycle promptly recovers routine and rides.
