Abstract
Bicycle of ratchet footboard that elasticity resets and operating method, it utilizes station appearance health gravity acting, and it is big to have drive power, and power conversion efficiency is high, footboard elasticity advantage such as reset for faster from road speed, mission radius multiplication, satisfy people light convenient, fast, mission radius big, green's the requirement of riding. Two ratchet footboard bilateral symmetry, the syntropy is parallel to the both sides of half -turn before big sprocket are installed at the same angle of inclination. The ratchet end is fixed at big chain dish centre of turning circle axis, and the footboard end is reciprocal circular motion about the axis is done, the drive cycling. The ratchet footboard is connected with the elastic component of fixing on the frame, after the acting, by the spring -driven of elastic component, replys to initial position.
Description
Technical field:
The utility model relates to a kind of bicycle and method of operation thereof of ratchet pedal of elastic reset, belongs to technical field of bicycles.
Background technology:
Bicycle is the vehicular traffic pedaled with manpower, step on, its structure is simple, be easy to manipulation, from heavy and light, be free to come and go, deposit use between convenience, short time, short distance very convenient, in the 1950's to the beginning of this century, be all the topmost trip instruments of Chinese.
Along with the development in city, the construction of functional area, city size is increasing, and the distance of people's trip is more and more far away, and add the quickening of rhythm of life, the defect of this conventional vehicles of bicycle also exposes out: the speed of a motor vehicle is slow; Require great effort by bike, consume individual energy, discomfort is fit to do the remote vehicle.
The speed of a motor vehicle is slow, and topmost reason of requiring great effort by bike is exactly that the mode of operation of the crank group of big chain plate causes:
1, the power conversion efficiency of stepping on is pedaled not high.
Existing bicycle is when riding, and bicyclist must step with both feet the sprocket wheel rotating and a pair reverse crank is housed, and by crank, the pedalling force of people is changed into rotary torsion, is delivered to flywheel by chain, then drive bicycle rear to advance.Crank produces the size of torsion, does not singly depend on the size of pedalling force, also depends on the size of the action direction line of power and the vertical distance-arm of force L at big chain plate center of gyration axis center.When crank is in front half-turn level attitude, arm of force L is maximum, and people pedal the power of stepping on can make chain wheel export acrotorque; And when being horizontal both sides, pedal the reduction of the arm of force of the power of stepping on and big chain plate center of gyration axis, the torsion that chain wheel exports reduces; When crank is in plumb position, pedal the power of stepping on through big chain plate center of gyration axis center, the arm of force is 0, steps on even if now firmly pedal, and chain wheel also torsionless exports.Half-turn after side crank proceeds to, the crank of opposite side enters the front half-turn position of acting, repeats the acting of above process.Proceed to rear half-turn crank not do work, opposite side pedal step on power effect under be turned back to plumb position above axis gradually, then enter next round acting process, go round and begin again.Visible, only have within the scope of descending each 45 ° in the horizontal plane, pedal and step on power loss reduction, chain wheel can be made to export more maximum torsion.
2, pedal step on power source be worth discussion.
Existing bicycle adopts riding in sitting posture, scrunches main contraction by people's thigh and buttocks muscles and produces power.When only having thigh firmly to step on pedal, chain wheel just outputting torsion drives bicycle.When thigh is not exerted oneself, chain wheel also torsionless exports.Human bady gravitational failing is transformed into the propulsive effort of bicycle.Only at upward slope, during propulsive effort wretched insufficiency, people just can leave a saddle, utilize body weight to drive bicycle.And rely on thigh and buttocks muscles to shrink to drive, long-distance thigh and the buttocks of riding can feel pain.
Can design a kind of rational in infrastructure, power transmission efficiently, all or mainly utilize body weight mark time traveling, fast, the new bicycle of suitable far away, near trip that radius of action is large? make to ride no longer hard, and fast power-saving environmental protection, give bicycle new vitality.
Summary of the invention:
From analyzing above: the crank that standard bicycle sprocket wheel is oppositely installed is intermittent acting; The torsion that acting exports therebetween is extremely uneven, and only within the scope of front half-turn horizontal surface up and down each 45 °, chain wheel exports acrotorque; Human bady gravitational failing is transformed into the propulsive effort of bicycle.
The ratchet bicycle with pedal of elastic reset of the present utility model is a kind of camber beam bicycle, and the crank that standard bicycle hinge wheel is oppositely installed is made into the ratchet pedal of the elastic reset of a pair cocurrent and parallel, the leg pedal power of standard bicycle sitting posture is done work, change into stand-type, with the gravity acting of own body weight.
The ratchet end of the ratchet pedal of the ratchet bicycle with pedal of elastic reset of the present utility model is fixed on big chain plate center of gyration axis, and pedal end is free end.Under health weight, pedal end does circular motion downwards around axis.Pedal rotates hinge wheel by shaft driving pawl, drives car motion.The corresponding hinge wheel corner of the upper and lower stroke S of pedal is about about 90 °, and L is the longest for the arm of force, and power waste is minimum, and chain wheel exports acrotorque.When side pedal travel is to lower limit position, centre of body weight is transferred on other one leg by bicyclist, steps on the ratchet pedal stepping on opposite side and enters acting process.Because of force of gravity, be in lower limit position pedal under the elastic force effect of elastic component, automatically return to upper extreme position, prepare the acting process entering next round, go round and begin again.
The utility model solves the technical scheme that its technical matters adopts:
The ratchet bicycle with pedal of elastic reset, is characterized in that: cancelled by the upper pipe of standard bicycle spider, retain the curved beam type bicycle of pipe, seat pipe; The crank that standard bicycle hinge wheel is oppositely installed is made into the ratchet pedal of a pair elastic reset in the same way; Two pieces of ratchet pedals are symmetrical, cocurrent and parallel, are arranged on the both sides of half-turn before hinge wheel with identical leaning angle; The ratchet end of the ratchet pedal of described elastic reset is fixed on big chain plate center of gyration axis, and pedal end is free end, and pedal end does reciprocal circular motion around axis; The ratchet pedal of described elastic reset is connected with the elastic component be fixed on vehicle frame, and after acting terminates, driven by the elastic force of elastic component, ratchet drive spindle automatically returns to initial position; Described elastic component is extension spring; Described elastic component is leaf spring; Described elastic component is gas spring; Described elastic component is stage clip; Described elastic component is torsion spring; Support with crossbeam is fixed on vehicle frame, the lower limit position of rack beam restriction ratchet pedal.
The beneficial effects of the utility model are: the ratchet bicycle with pedal design of elastic reset is rationally simple and direct, and gravity acting is more laborsaving, power is larger, and speed is faster, and radius of action doubles, meet that people are light, convenient and swift, radius of action is large, environmental protection, the requirement that the green of back to nature is ridden.
