Abstract

The invention belongs to a force storage device, especially relating to a force storage device which can improve the property of bicycle. The force storage device comprises a centre shaft sleeve and a centre shaft, between the buck wheel and the chain wheel being equipped with a spring board, and the two ends of the centre shaft being equipped with a foot linkage and a spring carrier. At usage, the foot linkage is stamped down by foots force and lifted by the spring carrier continuously, the continuous arc up-down alternative motion rotates the centre shaft and the buck wheel and winds continuously the spring bent plate, the force of every time is stored to change into rebound force and then release to the chain wheel, and the chain wheel forces the chain evenly and continuously to drive the bicycle. The device saves force, it is convenient, the speed per hour is high, and it is suit for single-leg people. The structure of the device is sample, the cost is low, and it is easy to produce.

Description

Force storage device

(1) technical field

The invention belongs to that a kind of screen resilience stores and release gear again, the force of explosion when being particularly suitable for storing bicycle running and scrunching then is used to the strength that stores the needs that travel automatically.

(2) background technology

As everyone knows, scrunch in the time of by bike all has very big force of explosion at every turn, however bicycle can not quicken suddenly, so these forces of explosion have only fraction to be utilized, other has all slatterned.Present bicycle has improved much than before, and it is faster more laborsaving that change-speed box can be ridden bicycle, the semi-mechanization state that has been improved to that has, and still, the force of explosion that is lost when scrunching never obtains utilizing.Therefore, bicycle needs a kind of force storage device that can the force of explosion when scrunching by bike stores especially, the rotation reinforcing of giving bicycle chainwheel then, and it is more laborsaving to allow bicycle ride.

(3) summary of the invention

Force storage device of the present invention, the force of explosion that will be wasted when at every turn scrunching by bike stores exactly, gives the rotation reinforcing of bicycle chainwheel then automatically, and it is faster, more laborsaving to allow bicycle running get up.

Force storage device of the present invention has an axle sleeve, an axis, but the pedal connecting rod that arc pumps is installed at the two ends of axis; The spring plank that can hold up pedal connecting rod is at any time installed in vehicle frame Upper shaft sleeve both sides; On the axis near the position screw thread of axle sleeve fixedly diving board take turns; In order to stop the contrarotation of axis and diving board wheel,, the roller bearing arrangement of clutch is installed all between axis and the pedal connecting rod, between diving board wheel and axle sleeve: the roller bearing arrangement of clutch by: holder, roller bearing are formed by, spring leaf four parts outward in roller bearing, the roller bearing; Sprocket wheel and diving board wheel are installed side by side; Between sprocket wheel and the diving board wheel reelable spring bent plate is installed, the outer ring of spring bent plate is fixed on the diving board wheel, and inner ring is fixed on sprocket wheel.

That does not stop in the time of by bike scrunches down pedal connecting rod, what spring plank did not stop again holds up pedal connecting rod come, the arc that pedal connecting rod does not stop up and down reciprocatingly scrunches, rotated axis and diving board wheel, the diving board of rotation is taken turns continuous winding spring bent plate outer ring, the force of explosion that the spring bent plate that twines sends when scrunching at every turn stores, the extremely strong bounce that produces is discharged to sprocket wheel by inner ring, sprocket wheel utilizes the bounce of spring bent plate, uniformly, continuous having an effect to chain, make chain rotate the drive bicycle quick continuously.

In order to make each turning unit firm and rotation is good, between axis and the axle sleeve, between axis and the pedal connecting rod, between axis and the steel plate wheel, steel plate take turns and sprocket wheel between, all install bearing or entad circumference put steel ball.

Force storage device of the present invention, simple and practical, cost is little, easily installation and maintenance, requirement on machining accuracy is not high, easily makes, and is fit to produce the appointed condition of former bicycle fully.During use, the cyclist no longer takes turns to scrunch as the pin rotation of traditional mode left and right sides, but both feet scrunch arbitrarily, can about single leg replace firmly, also can exert oneself together by both legs.Such design, it is laborsaving not only to reach the cyclist, also is particularly suitable for single leg people's use.

Figure two is depicted as the assembling cross-sectional view of diving board wheel assembly of the present invention

Figure three is depicted as the roller bearing arrangement of clutch position cross-sectional view among the present invention

Figure four is depicted as the spring plank position structural representation among the present invention

Among the figure: 1. axle sleeve, 2. axis, 3. pedal connecting rod, 4. roller bearing, 5. holder in the roller bearing, 6. roller bearing leans on outward, 7 spring leafs, and 8. diving board is taken turns, 8-1. diving board wheel inner chamber outer ring, 9. sprocket wheel, 9-1. sprocket wheel inner chamber inner ring, 10. spring bent plate, 11. diving boards wheel outer ring, 10-2. diving board wheel inner ring, 11. spring planks

(5) specific embodiments

As described in figure one to figure four is a kind of embodiment of the present invention, now specifies in conjunction with the accompanying drawings.Force storage device of the present invention has the axle sleeve (1) of fixing and a cycle frame, and axis (2) is installed in the axle sleeve, and pedal connecting rod (3) is installed at the axis two ends; On the axis near the position of axle sleeve fixedly diving board take turns (8), sprocket wheel (9) is installed in diving board and takes turns a side, mounting spring bent plate (10) between sprocket wheel and the diving board wheel, diving board inner chamber outer ring (8-1) is fixed in the outer ring of spring bent plate (10-1), and spring bent plate inner ring (10-2) is fixed in sprocket wheel inner chamber inner ring (9-1).Between above-mentioned pedal connecting rod and the axis, and axle sleeve and diving board wheel between, the roller bearing arrangement of clutch of being made up of by (6) and spring leaf (7) outward holder (5), roller bearing in roller bearing (4), the roller bearing all is installed.On the vehicle frame of above-mentioned axle sleeve both sides, the fixing spring plank (11) that can hold up pedal connecting rod at any time.

During use, cyclist's both feet can up and down reciprocatingly scrunch along camber line arbitrarily, the force of explosion that at every turn scrunches, can both drive axis and diving board wheel forces the rotation of spring bent plate to hold power, scrunch the bounce of being put aside continuously and can drive sprocket wheel drive wheel revolutions continuously, sprocket wheel drives wheel revolutions continuously, and bicycle can gradually quicken continuously.

Claims (1)

1. A power storage device, which has a shaft sleeve (1) fixed to the bicycle frame and a central shaft (2) wherein, it is characterized in that: the spring wheel is fixed adjacent to the shaft sleeve on the central shaft (8), the spring plate wheel is connected with the sprocket (9) through the spring bent plate (10); a pedal connecting rod (3) and its spring support are respectively installed on the two ends of the central axis along the arc to and fro plate (11); between the pedal connecting rod and the central shaft, between the bushing and the spring plate wheel, are installed with a roller (4), a roller inner support (5), a roller The axle is leaned on (6), and the roller clutch device that spring leaf (7) forms.
