Abstract
The utility model relates to a lever pedal type gear drive bicycle belongs to the bicycle field, adopts gear drive's technical scheme. Its characterized in that also has gear transmission set spare, footboard power component and footboard reset assembly, gear transmission set spare has two groups, and every group comprises a bull wheel, pinion, ratchet and axle, and the bull wheel excircle is the ratchet, and its interior circle be with little gear engagement's gear wheel, the pinion of two groups fix respectively the both sides of bicycle trailing axle and with big gear engagement, power component by the footboard, step on arm, pawl and pressure spring and constitute, footboard reset assembly includes pulley and tightrope cable, and the pulley is fixed on the frame and can be rotated, and tightrope cable process compresses tightly the outer disc of pulley, and its both ends are fixed on stepping on the arm. This scheme enables the gear drive with big drive ratio for speed and can not demeshing can alleviate hard with the longer arm of stepping on, has overcome sprocket, chain drive's shortcoming for the bicycle.
Description
Technical field
A kind of lever pedal gear-driving pedal car that this utility model is related to belongs to bicycle field(Including two-wheeled,
Three-wheel and carriage), it is a kind of laborsaving, quick running vehicle.
Background technology
Bicycle it is with a long history, mainly as running vehicle, the use range of the bicycle of on-electric is wide, use
Number is more, and its primary structure includes:Vehicle body frame, wheel, brake member, handle and driving member, existing bicycle driving member generally by
Sprocket wheel, chain drive, this kind of kind of drive has a disadvantage that:1st, transmission distance is big;2nd, the center of two sprocket wheels and chain is easily deviateed
Same plane, causes de- chain;3.Transmission resistance is big;4.Gear ratio is little.
The content of the invention
The utility model proposes a kind of lever pedal gear-driving pedal car, its purpose is to overcome bicycle chain
The gear-driven shortcoming of bar.
This utility model adopts gear-driven technical scheme.
For this purpose, this practical drive mechanism employs pedal gear transmission mode.
A kind of lever pedal gear-driving pedal car, including bicycle, it is characterised in that also gear-driven assembly, dynamic
Power component and pedal return unit, gear-driven assembly has two groups, is made up of bull wheel, little gear, ratchet and an axle per group, bull wheel
Cylindrical is ratchet, and its inner circle is the gear wheel engaged with little gear, bull wheel axle be fixed on gear-box and can pivoting, two
Group gear-box is connected and is fixed on vehicle frame, and two groups of little gear is separately fixed at both sides and and the gear wheel of bicycle hind axle
Engagement;Power Component by pedal, step on arm, ratchet and holddown spring and constitute, ratchet can be stepped on merging to be fixed on rotating shaft with ratchet
On arm, holddown spring two ends are separately fixed to be stepped on arm and ratchet;Pedal reset assembly includes pulley and flexible lines, and pulley is fixed
Simultaneously can rotate on vehicle frame, pulley periphery is passed through and compressed to flexible lines, its two ends is separately fixed at left and right and steps on arm.
This utility model can use the gear drive of big speed ratio, plus fast speed and without departing from engagement, can use longer
Arm is stepped on, mitigation is exerted oneself, overcome the shortcoming of bicycle sprocket wheel, chain drive.
Description of the drawings
Fig. 1 is the assembling schematic diagram of lever pedal gear-driving pedal car component;
Fig. 2 is gear-driven assembly pedal power component drawings;
Fig. 3 is pedal reset assembly figure.
Figure number:Rear axle 1, little gear 2, gear wheel 3, bull wheel 4, ratchet 5, ratchet 6, rear wooden fork 7, trailing wheel 8, pedal 9, step on
Arm 10, vehicle frame 11, pulley 12, soft rope 13, little axle 14, spring 15, Large Gear Shaft 16, gear-box 17.
Specific embodiment
Now technical solutions of the utility model are illustrated with a concrete example, Fig. 1-3 shows that the lever pedal gear of this example is passed
The structure and mutual relation of each component of dynamic bicycle.Including gear-driven assembly, pedal power component and pedal reset assembly;
Gear-driven assembly includes gear wheel 3, little gear 2, ratchet and axle, and the inner circle of the wheel hub of bull wheel 4 has gear wheel, and outer wheel hub has spine
Wheel 5, little gear is mounted in the both sides of rear axle 1 and can rotate, and gear wheel 3 is arranged on the both sides of rear wooden fork 7 and energy with Large Gear Shaft 16
Rotate;Gear wheel pedal power component includes pedal 9, steps on arm 10, ratchet 6, holddown spring 15 and little axle 14, and pedal 9 is fixed on
The end of arm 10 is stepped on, stepping on arm 10 and being fixed on Large Gear Shaft 16 and can rotate, the little axle 14 of ratchet 6 is fixed on steps on arm 10 and can be around little axle
14 rotate;Pedal reset group gear-driven assembly, pedal power component and pedal reset assembly;Gear-driven assembly includes canine tooth
Wheel, little gear, ratchet and axle, the inner circle of wheel hub has gear wheel, and outer wheel hub has ratchet;Gear wheel pedal power component includes stepping on
Plate, ratchet, holddown spring and axle;Pedal reset assembly includes pulley and flexible lines, and pulley 12 is fixed on vehicle frame 11, flexible lines
13 Jing pulley grooves are fixed on to be stepped on arm 10.
During cycling, foot is firmly pushed wherein while step on arm 10, ratchet 6 is entered the groove of ratchet 5 and is pressed by spring 15
Tightly, then ratchet 5 orders about bull wheel 4 and rotates, and bull wheel 4 rotates the little gear 2 being engaged with and promotes rear axle 1 to march forward;
At the same time, the 13 Jing pulleys of soft rope 12 stepped on arm 10 pull another side to step on arm 10 and move up, and the ratchet 6 stepped on arm 10 overcomes
The pressure of spring 15 is exited from the groove of ratchet 5;Now, this is stepped on downwards with another foot and step on arm, to drive another group of gear to pass
Dynamic component operation, such left and right foot is alternately trampled, and bicycle is continuously advanced.
