Description
Technical field
The utility model relates to a kind of driving device that is used for bicycle, a kind of specifically driving device of pedal type bicycle up and down reciprocatingly.
Background technology
Traditional bicycle drive all is that the rotary pedals formula is travelled, be both feet slam respectively two foot-operated before and after rotation trample and drive trailing wheel and rotate and travel, because both feet respectively all will be from the top down and are firmly stepped on backward and pedal, particularly step on backward must collude backward to draw just with leg when pedaling and to make bicycle walking, do not meet the state of nature that human body is exerted oneself, cause human consumption excessive thus, be easy to generate fatigue.
Summary of the invention
The utility model provides a kind of driving device of pedal type bicycle up and down reciprocatingly, only needs both feet up and down reciprocatingly to trample respectively bicycle is travelled easily.
The utility model comprises frame, stretcher and ratchet, the technical scheme that is adopted is: there is a cover commutation gear pair front portion in frame, the set respectively outer end, crank semiaxis both sides of this commutating tooth wheel set is connected with stretcher with the increment toggle-action lever by the telescoping crank bar, the sold inside the country tooth post that semi-circle gear sheet that commutating tooth wheel set both sides are fixed is provided with respectively with about the teeth twisting of two ratchets, a side outer end of described sprocket wheel axis is equipped with and is used for the floral disc sprocket wheel that rotating-wheel travels.
Described commutating tooth wheel set is two cone gears that the branch both sides are oppositely arranged, between adopt one or two relative taper reversing gear to carry out twisting to combine.
The telescoping crank bar of described frame both sides is can stretching structure, and an end of this telescoping crank bar is connected on the crank semiaxis of both sides, and the other end is connected with the axostylus axostyle of stretcher respectively.
Square toggle-action lever one end that increases of described both sides links to each other with the axostylus axostyle of stretcher respectively, and the other end is connected the both sides of frame respectively by pivot pin.
After the utility model is installed and is used for bicycle, during use, only need both feet to pump respectively and can make bicycle running by internal transmission transmission trailing wheel, owing to only need pump, keep strokes when walking with the people, the state of kinematic motion that meets human body natural's falling bodies, gravity by human body can allow bicycle running, the consumption that makes it human body reduces, solved and pedaled the problem that just can travel after present bicycle must be exerted oneself, can be widely used in installing and using of various bicycle and mans and three-wheel vehicle.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the utility model structural representation.
Fig. 2 installs the structural representation that is used for bicycle for the utility model.
In the accompanying drawing: 1, stretcher, 2, the telescoping crank bar, 3, increase the square toggle-action lever, 4, the commutating tooth wheel set, 5, the semi-circle gear sheet, 6, ratchet, 7, sold inside the country tooth post, 8, the crank semiaxis, 9, frame, 10, the floral disc sprocket wheel, 11, the sprocket wheel axis.
The specific embodiment
Shown in accompanying drawing 1 embodiment: there is a cover commutation gear pair 4 front portion in frame 9, the set respectively outer end, crank semiaxis 8 both sides of this commutating tooth wheel set 4 is connected with stretcher 1 with increment toggle-action lever 3 by telescoping crank bar 2, the sold inside the country tooth post 7 that semi-circle gear sheet that commutating tooth wheel set 4 both sides are fixed 5 is provided with respectively with about the teeth twisting of two ratchets 6, a side outer end of described sprocket wheel axis 11 is equipped with and is used for the floral disc sprocket wheel 10 that rotating-wheel travels.Commutating tooth wheel set 4 is two cone gears that the branch both sides are oppositely arranged, between adopt one or two relative taper reversing gear to carry out twisting to combine.The telescoping crank bar 2 of frame 9 both sides is can stretching structure, and an end of this telescoping crank bar 2 is connected on the crank semiaxis 8 of both sides, and the other end is connected with the axostylus axostyle of stretcher 1 respectively.Square toggle-action lever 3 one ends that increase of both sides link to each other with the axostylus axostyle of stretcher 1 respectively, and the other end is connected the both sides of frame 9 respectively by pivot pin.
Shown in accompanying drawing 2 embodiment: in the frame 9 of bicycle, crank axis 8 outsides institute bonded assembly telescoping crank bar 2 with increase square toggle-action lever 3 and link to each other with stretcher 1, take turns sheet 5 for semicircle in the floral disc sprocket wheel 10 that sprocket wheel axis 11 external side ends are adorned.During running condition, a stretcher is stepped on for 1 time, another stretcher 1 upwards lifts in the effect of commutating tooth wheel set 4, when operating so repeatedly, the semi-circle gear sheet of being fixed 5 promptly drives ratchets 6 by sold inside the country tooth post 7 and rotates to same direction, about promptly form continuous running state under the effect of two semi-circle gear sheets 5.
Foot-operated crank semiaxis 8 both sides institute bonded assembly telescoping crank bar 2 is designed to automatic telescopic structure about the utility model, with the principle of work that increases after square toggle-action lever 3 cooperates be: utilize the front and back offset distance that increases square toggle-action lever 3 and telescoping crank bar 2, when stepping stretcher 1, telescoping crank bar 2 just can extend gradually with the center of rotation that increases square toggle-action lever 3, when turning over, shortens gradually again after increasing square toggle-action lever 3 axle center by the telescoping crank bar, making it left and right sides stretcher 1 is the center of circle to increase square toggle-action lever 3, reciprocally swinging in its half cycle only, and telescoping crank bar 2 when reciprocally swinging thereupon by the flexible stroke of adjusting automatically.
Described commutating tooth wheel set 4 is two cone gears that the branch both sides are oppositely arranged, and be provided with a crank semiaxis 8 separately, the commutation cone gear twisting that can adopt one or two to be oppositely arranged between two cone gears, when the stretcher 1 of both sides is stepped on downwards, rotate by 8 bonded assembly cone gears of crank semiaxis thereupon, between the commutation cone gear cone gear backward rotation that then drives opposite side the stretcher 1 of an other side is upwards lifted, under when stepping on another stretcher, then drive on the other direction and lift, promptly form continuous transmission and so forth and make bicycle running.During enforcement, when the commutation cone gear between two cone gears is set to relative two, can adopt up and down relatively or front and back are oppositely arranged cone gear twisting with both sides.
The utility model structure design is ingenious rationally, utilizes the mode of human body walking deadweight to make bicycle running, and is laborsaving, driving efficiency is high, applicable to the transmission device of various bicycle and mans.
