Abstract
The utility model relates to a variable speed gear, comprising a shaft transmission apparatus which consists of umbrella-shaped gear clusters(1,2), a spline shaft with spine tooth(6) and a spline shaft(12). The utility model is characterized in that one of the spline shaft is connected with more than two variable gears(2, 4) which mesh with a toothed disk(15), the center of the toothed disk is fixed and connected with a driven shaft(16), and the other end of the spline shaft(12) is connected with a variable controller through a shift fork(8). The variable and transmission structure of the utility model is easy and light, which has advantages of flexible speed transmission, operation in closed state, pollution-free and anti-erosion nature as well as safe and reliable usage.
Description
(1) technical field: the utility model relates to a kind of variable speed bicycle, particularly a kind of driven off by shaft variable speed bicycle.
(2) background technology: variable speed bicycle mainly is the bicycle of chain gear, through people's long-term endeavour and improvement, market leading product and mature technology have been become, driven off by shaft variable speed bicycle is still among research and development, as a kind of Chainless bicycle variable-speed drive, mainly comprise initiatively castellated shaft and the hub splines that is enclosed within on the active castellated shaft, its both sides are suit one active multiplying wheel also, when the need speed change, hub splines is got to the another side variable-ratio from one side, this variable-speed drive structure more complicated, at least set up two multiplying wheels, but do not have expendable weight, in addition if under steam hub splines is got to another side, the difficult and gouging abrasion easily of engagement from one, influence service life, thereby be difficult to apply.
(3) summary of the invention:
The purpose of this utility model is that design is a kind of simple in structure, in light weight, can free under steam shifted bicycle.
Design plan of the present utility model is, a kind of shaft drive derailleur, it comprises by umbrella shape wheels, interior ratchet castellated shaft and castellated shaft forms driving device, a termination that it is characterized in that castellated shaft has two above variable gears, variable gear is meshed with a fluted disc, the center of fluted disc and axle drive shaft Joint; The other end of castellated shaft is connected with variable-speed controller by a shift fork.
The advantage of above-mentioned design plan is variable gear and fluted disc are made sealing state, and speed change and driving device move at sealing state, change-speed box is not easy to wear, is difficult for polluting the dirt thing, and prolong service life, shifted by the gear change hand lever on the handlebar, safe and reliable.

(5) specific embodiment:
The utility model is made up of shaft gearing and shaft type transmission system, and as shown in Figure 1, driving device comprises crowngear A and crowngear B, internal ratchet castellated shaft (6) and castellated shaft (12).Crowngear A and crowngear B engagement links, and A gear (1) axle is affixed with hind axle, the engagement that links to each other with flywheel shaft of B gear (2) axle.Between crowngear B and interior ratchet castellated shaft, establish the flywheel of forming by inner ratch gear (6), support tooth (3) and compression spring (4), the compression spring two ends are the support tooth on band inclined-plane, and the tooth of support up and down (3) of flywheel is with inner ratch gear (6) can nibble the clutch state that can divide.
Transmission system comprises castellated shaft (12), vertebra deformation speed gear (A) and vertebra deformation speed gear (B), double fluted disc (15) and axle drive shaft (16) composition, as shown in Figure 2, two variable gears of castellated shaft (12) one terminations (13,14), two vertebra deformation speed gear A, B are meshed with two radial teeth of row (22) on the rotary fluted disc (15) respectively.Fluted disc (15) center and pedal center shaft are the axle drive shaft Joint.Two variable gears (13,14) and fluted disc (15) are driven axle sleeve (19), fluted disc lid (23) and drive shaft sleeve (24) sealing of surrounding, and variable-speed drive is not stain by the dirt ash, so that the speed change ensuring smooth transmission increases the service life.
Variable-speed controller is made up of shift fork (8), pull bar (11), coil spring (10) drag-line and drag-line handle, one end of shift fork (8) and castellated shaft (12) join, the other end and pull bar (11) join, retracing spring (10) is placed in outside the pull bar (11), the other end of pull bar (11) links to each other with drag-line, and drag-line is connected with drag-line handle on being located at handlebar.
Speed change is by stirring the drag-line handle on the handlebar, make drag-line affect pull bar (11) reach, make shift fork (8) that floral axis is moved forward simultaneously, castellated shaft (12) is pulled out from second gear vertebra deformation speed gear (13), enter in one grade of vertebra deformation speed gear (14), finish speed change, if drag-line is loosened by second gear to a grade, under action of the spring, reset, finish by one grade of speed change to second gear.
Transmission process is to drive fluted disc (15) by pedal axle drive shaft (shown in the arrow of Fig. 1) to rotate, and passes to castellated shaft through vertebra shape tooth and rotates, and gives flywheel through interior sour jujube axle (6) transmission again, and crowngear (1,2) is given in the inner ratch gear transmission of flywheel, drives rear wheel and rotates.
The flywheel working process is as follows, and from rotation drive female splines inner ratch gear (6) rotation of castellated shaft (12), support tooth (3) drives umbrella shape tooth (2) and rotates under the effect of coil spring (4).Because of support tooth (3) is one-way only operation,, just changeing crowngear (1, the 2) work that drives when spring (4) inner ratch gear (6) and support tooth (3) engagement when outwards upholding.When wheel reversing, spring (4) inwardly shrinks inner ratch gear (6) jump out of mesh, and flywheel dallies.
