Description

Bicycle with lengthened arm pedal rod

Technical Field

The utility model belongs to the technical field of the bicycle, concretely relates to lengthened arm pedal lever bicycle.

Background

The bicycle in the current market is in pedal type chain wheel transmission, two pedal rods are vertically and fixedly distributed, and two pedals are alternately treaded and circularly move around a chain wheel.

Such designs are relatively simple and easy to operate, but tend to be relatively short due to the limited ground height of the foot bars, and therefore, to a relatively low power output. The rider can ride on the flat ground, and the rider feels hard when encountering a slope or a load.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the above problem, providing an extension arm pedal lever bicycle, the length of pedal lever extends to rear axle position department, and rack and pinion meshing transmission power increases output, makes to ride more lightly.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides an extension arm pedal pole bicycle, includes pedal pole, front wheel axle, rear wheel and frame, install saddle and handle on the frame, install big sprocket on the frame, the sprocket shaft position department of big sprocket installs the pinion, one-way bearing is installed at the center of pinion, little sprocket is installed to the rear wheel axle position department of rear wheel, big sprocket and little sprocket pass through the chain and connect, the pedal pole includes left pedal and right pedal, the other end of pedal pole is connected to rear wheel axle position department, the bottom of pedal pole is equipped with the torsional spring.

Preferentially, the method comprises the following steps: the frame is provided with an upper limit clamp and a lower limit clamp;

preferentially, the method comprises the following steps: the pinion is meshed with the left rack and the right rack;

preferably: the transmission structure of the pinion and the left rack and the right rack can also be applied to a manpower tricycle, a water bicycle and an electric power-assisted bicycle.

Compared with the prior art, the beneficial effects of the utility model reside in that:

the utility model provides a lengthened arm pedal lever bicycle comprises pedal lever, front wheel axle, rear wheel and frame, and the length of pedal lever extends to the central point department of putting of little sprocket, the bottom of pedal lever is equipped with the torsional spring, and the central point department of putting of pinion has installed one-way bearing, and one-way bearing locks when pedal lever forward motion. Pinion and left rack, right rack intermeshing provide power transmission for the gos forward of bicycle, have increased output for it is lighter to ride.

in the figure, 1, a front wheel, 2, a frame, 3, a large chain wheel, 4, a saddle, 5, a right rack, 6, a pinion, 7, a chain, 8, a rear wheel, 9, a small chain wheel, 10, an upper limit clamp, 11, a lower limit clamp, 12, a left rack, 13, a one-way bearing, 14, a front wheel shaft, 15, a handle, 16, a left pedal, 17, a right pedal, 18, a chain wheel shaft, 19, a torsion spring, 20 and a rear wheel shaft.

Detailed Description

In order to make the technical solution of the present invention better understood by those skilled in the art, the present invention will be further described with reference to the following specific embodiments, which are provided as illustration only and are not intended to limit the present invention.

The bicycle with the long arm pedal lever comprises a pedal lever, a front wheel 1, a front wheel shaft 14, a rear wheel 8 and a frame 2, wherein the frame is provided with a seat 4 and a handle 15, the frame 2 is provided with a large chain wheel 3, a small gear 6 is arranged in the large chain wheel 3, a one-way bearing 13 is arranged at the center of the small gear 6, a small chain wheel 9 is arranged at the position of a rear wheel shaft 20 of the rear wheel 8, and the large chain wheel 3 is connected with the small chain wheel 9 through a chain 7; the pedal rod comprises a left pedal plate 16 and a right pedal plate 17, the other end of the pedal rod is connected to the center of the small chain wheel 9, a torsion spring 19 is arranged at the bottom of the pedal rod, and an upper limiting clamp 10 and a lower limiting clamp 11 are mounted on the frame 2.

A pinion 6 is arranged at the position of a sprocket shaft 18 of the large sprocket 3, and the pinion 6 is meshed with the left rack 12 and the right rack 5 and is used for providing power transmission to the front part of the bicycle; the transmission structure of the pinion 6 and the left rack 12 and the right rack 5 can also be applied to vehicles such as a manpower tricycle, a water bicycle, an electric power-assisted bicycle and the like.

The utility model relates to a lengthened arm pedal lever bicycle, the one-way bearing locks when the pedal lever moves forward, the pedal lever motion drives the small sprocket to rotate, after the pedal power of any one side of left foot board or right foot board loosens, the pedal lever can bounce upwards to return to the high position under the effect of torsional spring, because install the one-way bearing, therefore, there is not reverse motion resistance and obstacle; the pedal rod on the other side adopts hysteresis motion, so that the pedal rods on the two sides can alternately move, and the bicycle is driven to move forwards. When the load is larger or the gradient is larger, the pedal rods on the two sides can also be simultaneously stepped down, the maximization of the output power is realized by concentrating the force, and the bicycle is lighter, more comfortable and more long-distance to ride.

The present invention is not described in detail in the prior art.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
