Technical Field

The invention relates to a bicycle, in particular to a light and fast bicycle capable of being freely switched by pedaling.

Background

As is known, the pedal of prior art's bicycle is whole circle pivoted, the people is at the in-process of changeing bicycle pedal a week with the pedal, divide area and the non-area of applying force, the pedal all exists area of applying force and non-area of applying force about promptly, so must influence the speed of riding, in addition, prior art's bicycle is only pedaled forward, the bicycle just moves ahead, monotonously no enjoyment, consequently, design one kind and not have the non-area of applying force freely step on freely and switch light swift bicycle at will, be the technical problem that needs to solve at present.

Disclosure of Invention

The invention aims to solve the technical problem of providing a light and fast bicycle capable of being freely switched by pedaling without a non-stressing area.

The first technical scheme for solving the technical problems of the invention is as follows:

Step on freely and switch light swift bicycle at will, which comprises a vehicle rack, it violently manages I to be equipped with on the underbeam of frame, it is equipped with axle I through rotary part soon in violently managing I, except installing the sprocket that corresponds with the epaxial flywheel of trailing axle on axle I, it installs two vertical roller wheels of flywheel formula still to symmetry on axle I, be fixed with the pole on the vertical roller wheel outer lane of flywheel formula, be equipped with the footboard in the outer end of pole, front end at the underbeam is equipped with vertical trunnion, horizontal roller wheel is equipped with on vertical trunnion top spin, horizontal roller wheel and the vertical roller wheel of two flywheel formulas are stirred the formula and are meshed. Due to the guiding effect of the transverse cone (7), when one pedal is treaded downwards, the other pedal moves upwards, so that different pedals are alternated, and the pedals treaded by two feet are always in a stress application area.

As a preferable scheme of the first technical scheme of the invention, the transverse cone is a sharp-tooth cone or a rectangular-tooth cone; likewise, the flywheel type longitudinal roller cone is a sharp tooth type roller cone or a rectangular tooth type roller cone.

As a preferable mode of the first technical means of the present invention, the transmission wheel is a flywheel or a sprocket.

the second technical scheme for solving the technical problems of the invention is as follows:

Step on freely and switch light swift bicycle at will, which comprises a vehicle rack, violently manage I and violently manage II on the underbeam of frame, be equipped with axle I through rotary part soon in violently managing I, be equipped with axle II through rotary part soon in violently managing II, install two vertical gear wheels of flywheel formula in I symmetry of axle, be fixed with the pole on the vertical gear wheel outer lane of flywheel formula, be equipped with the footboard in the outer end of pole, front end at the underbeam is equipped with vertical trunnion, horizontal gear wheel is equipped with horizontal gear wheel at vertical trunnion top spin, horizontal gear wheel and the vertical gear wheel of two flywheel formulas stir the formula meshing, install the sprocket that corresponds with the epaxial flywheel of trailing axle at axle II, gear I is still installed on axle II, gear II is still installed at axle I, gear I and gear II. Due to the guiding effect of the transverse cone, when one pedal is treaded downwards, the other pedal moves upwards, so that different pedals are alternated, and the pedals treaded by two feet are always in a stress application area.

as a preferable mode of the second technical means of the present invention, the transmission wheel is a flywheel or a sprocket.

In a preferred embodiment of the second aspect of the present invention, the diameter of the gear ii is larger than the diameter of the gear i. Because the diameter of gear II is greater than the diameter of gear I, and the gear ratio is bigger promptly, tramples the footboard the same number of times in the same time, and the bicycle runs sooner.

In a preferred embodiment of the second aspect of the present invention, gear i is on the left side of shaft ii, and likewise gear ii is on the left side of shaft i.

As a preferable scheme of the second technical scheme of the invention, the transverse cone is a sharp-tooth cone or a rectangular-tooth cone; likewise, the flywheel type longitudinal roller cone is a sharp tooth type roller cone or a rectangular tooth type roller cone.

Compared with the prior art, the pedal can be half-pedaled (the pedals are alternated at the stress application area one by one) or fully pedaled (the pedals move along with the chain wheel in a whole circle like riding a common bicycle), half-pedaled is adopted when the bicycle goes up a slope or is accelerated, the pedals are pedaled by two feet and are always in the stress application area, and the bicycle runs faster; when full pedaling is adopted, one rotates forwards and the other rotates backwards, the entertainment of riding the bicycle is increased, but the chain wheel always rotates forwards no matter the bicycle rotates forwards or backwards; and because the transverse gear wheel is in poking type engagement with the two flywheel type longitudinal gear wheels, the friction resistance is small, and the labor is saved.

Detailed Description

as shown in figure 1, the light and fast bicycle capable of being freely switched by pedaling comprises a frame, wherein a transverse pipe I1-1 is arranged on a lower beam 1 of the frame, a shaft I2 is rotatably arranged in the transverse pipe I1-1 through a rotating part, two flywheel type longitudinal cones 4 are symmetrically arranged on the shaft I2 besides a chain wheel 3 corresponding to a flywheel on a rear wheel shaft, a rod 5 is fixed on the outer ring of each flywheel type longitudinal cone 4, a pedal 5-1 is arranged at the outer end of the rod 5, a longitudinal trunnion 6 is arranged at the front end of the lower beam 1, a transverse cone 7 is rotatably arranged on the longitudinal trunnion 6, and the transverse cone 7 is in poke-type engagement with the two flywheel type longitudinal cones 4. The driving wheel is a flywheel or a chain wheel. Due to the guiding effect of the transverse cone 7, when one pedal 5-1 is trodden downwards, the other pedal 5-1 moves upwards, so that different pedals 5-1 are rotated, and the pedals are always trodden by two feet in a stress application area.

The transverse cone 7 is a sharp tooth type cone or a rectangular tooth type cone; likewise, the flywheel type longitudinal roller cone 4 is a sharp tooth type roller cone or a rectangular tooth type roller cone.

As shown in figure 2, the light and fast bicycle capable of being freely switched by free pedaling comprises a bicycle frame, a transverse pipe I1-1 and a transverse pipe II 1-2 are arranged on a lower beam 1 of the bicycle frame, a shaft I2 is screwed in the transverse pipe I1-1 through a rotating part, a shaft II 8 is screwed in the transverse pipe II 1-2 through a rotating part, two flywheel type longitudinal cones 4 are symmetrically arranged on the shaft I2, a rod 5 is fixed on the outer ring of each flywheel type longitudinal cone 4, the outer end of the rod 5 is provided with a pedal 5-1, the front end of the lower beam 1 is provided with a longitudinal trunnion 6, a transverse cone 7 is arranged on the longitudinal trunnion 6 in a rotating way, the transverse cone 7 is in poking engagement with the two flywheel type longitudinal cones 4, a chain wheel 3 corresponding to a flywheel on a rear wheel shaft is arranged on the shaft II 8, a gear I9 is further arranged on the shaft II 8, a gear II 10, a gear I9 and a gear II 10 are further arranged on the shaft I2. The driving wheel is a flywheel or a chain wheel. Due to the guiding effect of the transverse cone 7, when one pedal 5-1 is trodden downwards, the other pedal 5-1 moves upwards, so that different pedals 5-1 are rotated, and the pedals are always trodden by two feet in a stress application area.

The diameter of the gear II 10 is larger than that of the gear I8. Since the diameter of the gear II 10 is larger than that of the gear I8, namely the speed change ratio is larger, the bicycle runs faster by treading the pedals the same number of times in the same time.

Gear I9 is to the left of shaft II 8, as is gear II 10 to the left of shaft I2.

The transverse cone 7 is a sharp tooth type cone or a rectangular tooth type cone; likewise, the flywheel type longitudinal roller cone 4 is a sharp tooth type roller cone or a rectangular tooth type roller cone.
