Bicycle because it is economical, convenient, flexible, pollution-free, it is free to stop, and is extensively adopted by the family of China and individual.Although along with the improvement of people's life, main flow walking-replacing tool and machinery of riding instead of walk constantly upgrade, from bicycle to bus, from bus to motor bike, again from motor bike to sedan, this development tendency is just in the ascendant, but society, nature, the economic dispatch problems such as incident energy shortage, environmental pollution, traffic congestion are becoming the powerful resistance of this development tendency of restriction also.Can predict, in the decades in future, no matter in the city of China or rural area, most population is also used as the most basic walking-replacing tool by bicycle.
Bicycle belongs to one and simply to ride instead of walk machinery, through the development of centuries, although technically very mature and stable, be difficult to occur technical important breakthrough again, but, bicycle commercially available at present still has following shortcoming: its pedal power mechanism utilizes foot-operated 360 degree of circulations to drive wheel to advance, foot-operated circulation is driven by foot and inertial rotation realizes, to go to level attitude by topmost position dextrorotation be the process that foot-operated power arm increases gradually foot-operated, and to go to lowermost end position in foot-operated continuation by above-mentioned level attitude dextrorotation be the process that foot-operated power arm reduces gradually, when foot-operated be in top and lowermost end position time its power arm be zero, this just makes bicyclist cannot to exert a force work done, can can only be passed through by the inertia of vehicle itself, when riding on the slope that the gradient is larger, also need to overcome larger vehicle self resistance, it is foot-operated by above-mentioned zero power arm position that this just makes bicyclist to make like a cork, ride to climbing and bring extreme difficulties.
Summary of the invention
Technical problem to be solved in the utility model is for above-mentioned the deficiencies in the prior art, a kind of bicycle reciprocating pedal driving actuating unit is provided, it effectively can solve the drawback that existing pedal power mechanism needs to utilize inertia by its zero power arm position, climbing is ridden lighter.
The technical scheme that the utility model adopts is: a kind of bicycle reciprocating pedal driving actuating unit, comprise the fixed muffle fixing with cycle frame, rotary sleeve is connected on quill in above-mentioned fixed muffle and rotary sleeve and is connected on interior axle in above-mentioned quill, the position that described fixed muffle given prominence to by described quill is provided with the first pedal unit and the first ratchet, described quill is provided with the first Bringing-back mechanism for making described first ratchet reset, the position that described interior aixs cylinder goes out described quill is provided with the second pedal unit and the second ratchet, described interior axle is provided with the second Bringing-back mechanism for making described second ratchet reset.
As preferably, described fixed muffle and described quill are by ball or bearing rotary socket, and described quill and described interior axle are by ball or bearing rotary socket.
As preferably, described first pedal unit and described second pedal unit are separately positioned on the left and right sides of cycle frame.
As preferably, described first ratchet and described second ratchet are disposed side by side on the same side of cycle frame, and simultaneously for driving bicycle wheel disc to rotate.
As preferably, cycle frame is provided with limit base, described interior axle is provided with the limited post coordinating with above-mentioned limit base and limit above-mentioned interior axle rotational angle.
As preferably, described first Bringing-back mechanism is retracing spring, and its one end is arranged on cycle frame or fixed muffle, and its other end is arranged on the race, inner of described first ratchet.
As preferably, described second Bringing-back mechanism is retracing spring, and its one end is arranged on cycle frame, and its other end is arranged on described interior axle.
The beneficial effects of the utility model are: because the utility model adopts said structure, both sides are foot-operated avoids zero power arm position all the time, foot-operated being operated drives wheel disc to advance, pedal force then can automatically restore to original position after disappearing under Bringing-back mechanism effect, realize reciprocating pedal driving process, solve traditional footstep mechanism to need to utilize inertia just by the problem of zero power arm position, climbing is ridden lighter.

Detailed description of the invention
Below in conjunction with the accompanying drawings and the specific embodiments the utility model is described in further detail.
As shown in Figure 1, a kind of bicycle reciprocating pedal driving actuating unit, comprise the fixed muffle 2 fixing with cycle frame 1, rotary sleeve is connected on quill 3 in above-mentioned fixed muffle 2 and rotary sleeve and is connected on interior axle 4 in above-mentioned quill 3, rotation socket can be carried out by ball or bearing between fixed muffle 2 and quill 3 and between quill 3 and interior axle 4, also rotation socket can be carried out by alternate manner, as long as it can realize the object that quill 3 freely can rotate in fixed muffle 2 and interior axle 4 can rotate in quill 3, in the present embodiment according to user demand and adopt between space requirement determination fixed muffle 2 and quill 3 ball carry out rotation socket, and adopt bearing to carry out rotation between interior axle 4 and quill 3 to be socketed.
The position that described fixed muffle 2 given prominence to by described quill 3 is provided with the first pedal unit 5 and the first ratchet 6, described quill 3 is provided with the first Bringing-back mechanism 7 for making described first ratchet 6 reset, the position that described interior axle 4 gives prominence to described quill 3 is provided with the second pedal unit 8 and the second ratchet 9, and described interior axle 4 is provided with the second Bringing-back mechanism 10 for making described second ratchet 9 reset.First pedal unit 5 and the second pedal unit 8 are separately positioned on the left and right sides of cycle frame 1, form left-hand tread plate and the right-hand tread plate of bicycle respectively.First ratchet 6 and the second ratchet 9 are disposed side by side on the same side of cycle frame 1, and simultaneously for driving bicycle wheel disc 11 to rotate, be more convenient for driving bicycle wheel disc 11 to rotate, first ratchet 6 and the second ratchet 9 can be two independent ratchet structures, also can be the ratchet structures of the outer race global formation of the first ratchet 6 and the second ratchet 9.Cycle frame 1 is provided with limit base 12, described interior axle 4 is provided with and coordinates with above-mentioned limit base 12 limited post 13 limiting above-mentioned interior axle 4 rotational angle.Limited post 13 is after rotating along with interior axle 4, and when pedal unit turns to extreme lower position, the limited seat 12 of limited post 13 stops, the range stepped under namely reaching pedal unit.
As preferably, described first Bringing-back mechanism 7 is retracing spring, and its one end is arranged on cycle frame 1 or fixed muffle 2, and its other end is arranged on the race, inner of described first ratchet 6.Described second Bringing-back mechanism 10 is retracing spring, and its one end is arranged on cycle frame 1, and its other end is arranged on described interior axle 4.
Because the utility model adopts said structure, both sides are foot-operated avoids zero power arm position all the time, foot-operated being operated drives wheel disc to advance, pedal force then can automatically restore to original position after disappearing under Bringing-back mechanism effect, realize reciprocating pedal driving process, do not need just can realize self-return through zero passage power arm position, solving traditional footstep mechanism needs to utilize inertia just by the problem of zero power arm position, climbing is ridden lighter.
The above, be only the utility model preferred embodiment, therefore can not limit with this scope that the utility model implements, the equivalence namely done according to the utility model claim and description change with modify, all should still belong in scope that the utility model patent contains.
