Description
Technical field
The utility model relates to a kind of bicycle driver.
Background technology
Existing bicycle is common in bicycle and three-wheel vehicle.The actuating device of existing bicycle mainly is made of left and right foot-operated actuating arm (all disposing pedal), driving arm axle, sprocket wheel, chain, rear axle and flywheel (being the overriding clutch that has the gear teeth on the wheel rim), left and right foot-operated actuating arm is all captiveed joint with the driving arm axle with sprocket wheel, and be rotating shaft all to drive arm axle, chain is meshed with sprocket wheel and flywheel simultaneously, rotate by foot-operated actuating arm drive sprocket, give flywheel through chain with transmission of power again, and then make flywheel drive the rotation of trailing wheel axle sleeve, realize driving to the bicycle trailing wheel.When above-mentioned existing actuating device is worked, the both feet of human body need be stepped on left and right pedal and make it to do circular movement, final effect analysis from the application of force, only when pedal moves to the place ahead that drives arm axle, human body could produce the actv. rotating torque to driving arm axle to stepping on of pedal, and then drive sprocket wheel rotation, simultaneously, have only when pedal move to the place ahead of driving arm axle and foot-operated actuating arm and horizontal angle than hour, the arm of force of stepping on power just is tending towards maxim, and it is maximum that the rotating torque of generation also promptly is tending towards.And when foot-operated actuating arm and horizontal angle are big (that is with vertical direction on angle hour), even pedal is positioned at the place ahead that drives arm axle,, so also can only produce less rotating torque because it is less to step on the arm of force of power.The efficient of above-mentioned existing bicycle driver is lower, and the bicyclist comparatively requires great effort in use, thereby awaits improving.
The utility model content
The purpose of this utility model is that the actuating device to existing bicycle improves, and a kind of application of force better effects if, the laborsaving fast unit of bicycle that efficient is higher are provided.
The laborsaving fast unit of bicycle of the present utility model has the wheel axle sleeve, first pedal, second pedal, the first foot-operated actuating arm, the second foot-operated actuating arm and can be with described first, the second foot-operated actuating arm is articulated in the driving arm axle on the vehicle frame, first pedal and second pedal are separately positioned on an end of the first foot-operated actuating arm and an end of the second foot-operated actuating arm, it is characterized in that being provided with first drive sprocket, second drive sprocket, driving chain wheel, the drive sprocket supporting structure, the driving chain wheel supporting structure, first chain drive-belt, second chain drive-belt, driving chain, first flywheel and second flywheel, the wheel shaft of the wheel shaft of described first drive sprocket and second drive sprocket supports by the drive sprocket supporting structure, the wheel shaft of described driving chain wheel is supported by the driving chain wheel supporting structure, described first flywheel and second flywheel are individually fixed in the two ends of wheel axle sleeve, one end of described first chain drive-belt is fixed on the first foot-operated actuating arm, the other end of described first chain drive-belt is walked around first drive sprocket successively, first flywheel and being connected with an end of driving chain, one end of described second chain drive-belt is fixed on the second foot-operated actuating arm, the other end of described second chain drive-belt is walked around second drive sprocket successively, second flywheel and being connected with the other end of driving chain, described driving chain is wound on the driving chain wheel, the gear teeth of the gear teeth of first drive sprocket and first flywheel all are meshed with the cuff link of first chain drive-belt, the gear teeth of the gear teeth of second drive sprocket and second flywheel all are meshed with the cuff link of second chain drive-belt, and the gear teeth of described driving chain wheel are meshed with the cuff link of driving chain.
In the utility model, above-mentioned drive sprocket supporting structure and driving chain wheel supporting structure all can be axle bearing seat (inside can be provided with bearing) or similar structures such as axle bearing frame, cramp bar.
When using the laborsaving fast unit of bicycle of the present utility model, can be connected with bicycle frame driving arm axle, utilize drive sprocket supporting structure and driving chain wheel supporting structure to make the wheel shaft of the wheel shaft of first, second drive sprocket and driving chain wheel supported on vehicle frame respectively, and with the axle sleeve of the axletree cover in this device as cycle wheel (be generally trailing wheel, but also can be front-wheel).Like this, when alternately stepping on first, second pedal (being commonly called as left and right pedal), just can drive the bicycle motion.For example, when stepping on first pedal downwards, the first foot-operated actuating arm will be that rotating shaft turns an angle to drive arm axle, and spur first chain drive-belt motion thus, the sport of first chain drive-belt is rotated first drive sprocket and first flywheel, thereby realizes the driving to wheel axle sleeve and cycle wheel.Because first chain drive-belt links to each other with an end of driving chain, the driving chain other end links to each other with second chain drive-belt again, one end of second chain drive-belt then is fixed on the second foot-operated actuating arm, and this just makes between first, second foot-operated actuating arm and has realized interlock.When the first foot-operated actuating arm moved downward, because the existence of this interaction relation, second foot-operated actuating arm was corresponding is pulled up, thereby is convenient to allow the bicyclist that position second pedal is thereon stepped on downwards.When the bicyclist stepped on second pedal downwards, move downward and can make second drive sprocket and second flywheel of second pedal rotated, and continue the driving of realization to wheel axle sleeve and cycle wheel.Similar with the motion of first pedal, moving downward in the process of second pedal, can the first foot-operated actuating arm be pulled upwardly by the effect of driving chain again, step on first pedal downwards for the bicyclist.Move in circles thus, just can realize continuous drive bicycle.
Because the motion of the pedal of the utility model device is for upper and lower circular motion but not circular movement, and pedal is to the foot-operated actuating arm application of force time, foot-operated actuating arm and horizontal angle are less usually, for driving arm axle, the arm of force of pedal application force is longer, and the moment of generation is corresponding bigger, therefore, compared with the aforementioned existing similar products, device of the present utility model has the labour-saving advantage.
Content of the present utility model further illustrates with the following Examples, but content of the present utility model is not limited only to content related among the embodiment.
