On, right crus of diaphragm steps down on the 4th pedal 501, and the first pedal 400, the second pedal 401 are opposite together with first slide 21
Make axially to reciprocatingly slide back and forth in the first guide rail 20, the first stampede part 40 drives 42 turns of the first driving wheel by the first transmission belt 41
It is dynamic, and then intermediate propeller shaft 6 is driven to rotate, third pedal 500, the 4th pedal 501 are opposite together with second slide 31
Make axially to reciprocatingly slide back and forth in the second guide rail 30, the second stampede part 50 drives 52 turns of the second driving wheel by the second transmission belt 51
It is dynamic, and then intermediate propeller shaft 6 is driven to rotate, intermediate propeller shaft 6 passes through the transmission of third transmission belt 8 and the 4th driving wheel 70 again,
Drive shaft of rear wheel 7 is imparted power to, and then drives rear wheel.Four sets of straight line stampede bodies are reduced to two sets of straight lines to trample
After mechanism, the left and right foot of left side bicyclist needs to make forward or backward simultaneously straight reciprocating motion, and the right crus of diaphragm of the right bicyclist needs
To make straight reciprocating motion forward or backward simultaneously, when one rides, bicyclist's seat is intermediate, and left foot steps down in the second pedal 401
On, right crus of diaphragm steps down on third pedal 500, and left and right foot does not need to keep synchronizing forward backward, because what is matched with left foot is
First guiding mechanism 2, the second guiding mechanism 3 matched with right crus of diaphragm, and in riding by two-person, the left and right foot of bicyclist shares one
A guiding mechanism, it is therefore desirable to left and right foot be kept to synchronize forward backward.
Embodiment 2
In embodiment 1, the first transmission belt 41 and the second transmission belt 51 are passed by the transmission driving rear-wheel of intermediate propeller shaft 6
Moving axis 7, and in the present embodiment, it is not provided with intermediate propeller shaft, setting and the first transmission belt 41 directly on drive shaft of rear wheel 7
The first driving wheel matched and the second driving wheel matched with the second transmission belt 51, by the first transmission belt 41 and the second transmission
Band 51 directly drives drive shaft of rear wheel 7.
In conclusion the bicycle drive in the utility model subtracts four sets of straight line stampede bodies in the prior art
It is less two sets of straight line stampede bodies, and corresponding two sets of straight line stampede bodies have carried out structure to the stampede part being matched therewith and changed
Into reducing manufacturing cost and manufacture difficulty to enormously simplify structure.
The principles and effects of the utility model creation, and the reality that part uses only is illustrated in the above embodiments
Example is applied, is rather than limited the present invention；It should be pointed out that for those of ordinary skill in the art, not departing from this
Under the premise of utility model concept, various modifications and improvements can be made, these belong to the protection of the utility model
Range.
