The bicycle changes the gear position inthe form of kicking type, so that the change of chain wheels is realized and the gear shifting is achieved.
Description
Technical field
The utility model relates to a kind of bicycle, and especially a kind of employing kicks two grades of double-stranded bar variable speed bicycles of formula.
Background technology
At present, the sprocket wheel that known bicycle again can not speed change, the Regular Bicycle of chain gear also have the mountain bike and the racing car of the sprocket wheel chain gear of variable-ratio, also have the bicycle of some other mode transmissions.The bicycle of sprocket wheel chain gear that generally can not speed change, most transmission multiplying powers of 48 teeth/21 teeth that adopt are ridden, and run into to go up a slope and when having than the weight body again, and are just very hard.And the mountain bike and the racing car of the sprocket wheel chain gear of variable-ratio because vehicle, structure, purposes and cost is different, are not suitable for the vehicle as loads.
The utility model content
In order to solve the problems of the technologies described above, the utility model proposes a kind of two grades of double-stranded bar variable speed bicycles of formula that kick, it changes the position of shelves with the form that kicks, thereby realizes the change of sprocket wheel, realizes gearshift.
The technical scheme that the utility model adopted is: a kind of two grades of double-stranded bar variable speed bicycles of formula that kick, comprise that left foot pedals that nut, left foot push off, front bowl, axis, support that bowl, ball, backstop bowl, nut, right pedal nut, right crus of diaphragm push off, right sprocket wheel, left sprocket wheel and vehicle frame, but place, the axle center of described axis is provided with the displacement axle of sway, fixedly install block key on the described displacement axle, on the described axis opening is set, described block key stretches out from this opening with right sprocket wheel or left sprocket wheel and is connected; Perforate also is set on the described axis, setting nut is installed in this perforate and by power assistant spring bonded assembly locating dowel pin, secondary notch cuttype groove is set on the described displacement axle, this groove contacts with described locating dowel pin.
As a kind of optimal way of the present utility model, described displacement axle one end is installed foot valve, other end mounting spring.
As a kind of optimal way of the present utility model, foot valve is installed at described displacement axle two ends respectively.
The beneficial effects of the utility model are: it can not only be ridden and loads as Regular Bicycle, and has increased a low gear, can be more easily laborsaving when upward slope or loads.Its core component is the speed change axis.The form of speed change axis has two kinds: a kind of is to adopt unidirectional propelling foot valve, and locating dowel pin blocks the displacement axle, the sprocket wheel of block key card master the inside; Advancing foot valve, locating dowel pin is upspring, and the displacement axle is ejected by spring, and the sprocket wheel of block key card master outside is realized gearshift; Another kind is to adopt two-way propelling foot valve, and corresponding locating dowel pin blocks the displacement axle, and corresponding block key blocks the sprocket wheel on opposite, advances foot valve from another side again, and corresponding locating dowel pin blocks the displacement axle, and corresponding block key blocks the sprocket wheel on opposite, thereby realizes gearshift.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is made further specific description in detail.
Fig. 1 is first kind of structural representation that kicks two grades of double-stranded bar variable speed bicycles of formula;
Fig. 2 is that the A-A of Fig. 1 is to partial enlarged drawing;
Fig. 3 is second kind of structural representation that kicks two grades of double-stranded bar variable speed bicycles of formula;
The specific embodiment
The utility model has proposed a kind of two grades of double-stranded bar variable speed bicycles of formula that kick, as depicted in figs. 1 and 2.Front bowl 3 contacts with vehicle frame 20, supporting bowl 9 directly twists on the axis, support and establish row's ball between bowl 9 and the front bowl 3, regulate the position of supporting bowl 9 and left sprocket wheel 18, front bowl 3 and vehicle frame 20 are adjacent to, thereby realize separating of axis and car body, and fixed the position of axis 5, axis 5 can freely rotate.Regulate the position of backstop bowl 12, make and support bowl 9, left sprocket wheel 18, right sprocket wheel 17 each other by the ball isolation, left sprocket wheel 18, right sprocket wheel 17 are separated with axis 5 also can freely rotate; Respectively one on nut about 13 prevents each the parts slippage on the axis 5.Porose on axis 5, installing in the hole is locating dowel pin 4, power assistant spring 7 and setting nut 6, is used for regulating the dynamics of power assistant spring 7.Axis 5 two ends are made similar Xie block structure and right crus of diaphragm and are pushed off and 16 cooperate, and transfer torque, right pedal nut 14 directly are screwed to and are used for fixing right crus of diaphragm 16 positions that push off on the axis 5, avoid 16 slippages that push off of the pin right side.
The utility model comprises two kinds of throw-over schemes altogether:
First kind of speed change scheme as shown in Figure 1, this moment, block key 11 stuck right sprocket wheel 17, axis 5 is being with right sprocket wheel 17 to rotate, and rotates thereby drive trailing wheel by chain; With foot valve 15 foot valves, displacement axle 8 just is pushed into, and locating dowel pin 4 blocks the groove of displacement axle 8 under the effect of power assistant spring 7, and this moment, block key 11 blocked left sprocket wheel 18, and axis 5 is being with left sprocket wheel 18 to rotate, and rotates thereby drive trailing wheel by chain; Promote foot valve 15 more inwards, locating dowel pin 4 is upspring, and displacement axle 8 is got back to initial position under the effect of spring 19, and block key 11 blocks right sprocket wheel 17 once more, thereby has realized speed change.
Second kind of speed change scheme as shown in Figure 3, the locating dowel pin on this moment the right sticks the groove of displacement axle 8, block key 11 sticks left sprocket wheel 18, axis 5 is being with left sprocket wheel 18 to rotate, and rotates thereby drive trailing wheel by chain; With kicking foot valve 15, the locating dowel pin 4 on the right is upspring, and displacement axle 8 moves to left, and the locating dowel pin 4 on the left side just blocks the groove of displacement axle 8, and block key 11 just blocks right sprocket wheel 17, and this moment, axis 5 was with right sprocket wheel 17 to rotate, and rotated thereby drive trailing wheel by chain; With kicking foot valve 15, the locating dowel pin 4 on the left side is upspring again, and displacement axle 8 moves to right, and the locating dowel pin 4 on the right blocks the groove of displacement axle 8, and block key 11 sticks left sprocket wheel 18, gets back to initial condition, thereby has realized speed change.
This that the utility model proposes kicks two grades of double-stranded bar variable speed bicycles of formula and can not only ride and loads as Regular Bicycle, and increased a low gear, can be more easily laborsaving when upward slope or loads.
