Abstract
The utility model discloses a bicycle driving device, comprising a drive sprocket meshed with a bicycle chain, an eccentric wheel arranged in the drive sprocket, a centre shaft penetrating through the eccentric wheel, two pedals arranged at two ends of the center shaft, and a connection block for connecting one pedal with the drive sprocket, wherein the drive sprocket is provided with a first positioning column and a second positioning column arranged opposite to the first positioning column, the connection block is provided with a first sliding chute matched with the first positioning column in a sliding manner, each pedal is provided with a second sliding chute matched with the second positioning column in the sliding manner, and an angle is kept between the two pedals. Since the eccentric wheel is arranged, and the angle is kept between the two pedals, when one pedal is in a vertical position, the other pedal can be in an inclined position; therefore, when the pedals are stepped down, the labor can be saved, and the directions of movement of the pedals are kept consistent thus the loss of kinetic energy is reduced; and furthermore, the movement of the pedals can transmit through small force arm areas rapidly so that the movement efficiency can be greatly improved.
Description
Technical field
The utility model relates to a kind of bicycle driving device.
Background technology
Existing bicycle driving device is by axis, be installed in foot-operated composition of sprocket wheel and crank-type on the axis.Because sprocket wheel is circular fluted disc, axis is arranged on the center of circular fluted disc.When foot-driven lever rotated near vertical position, its arm of force was very little, and this moment, its driving efficiency was extremely low.A kind of in addition firmly answering directly stepped on actuating device, though solved the problem of above-mentioned low efficiency transmission, in motion process, wants continuous conversion sense of motion because of riding, and its kinetic energy rejection is more, and sport efficiency is reduced.
The utility model content
The technical matters that the utility model will solve provides a kind of simple in structure, the bicycle driving device that sport efficiency is high.
For solving the problems of the technologies described above; The utility model adopts following technical scheme: comprise and cycle chain ingear drive sprocket; And be arranged on the eccentric wheel in the drive sprocket; And run through eccentric axis, and be arranged on two of the axis two ends foot-operated, and be used to connect wherein the contiguous block of foot-operated and a drive sprocket; Second registration mast that said drive sprocket is provided with first registration mast and is oppositely arranged with first registration mast, said contiguous block are provided with first chute with the first registration mast bearing fit; Said foot-operated second chute that is provided with the second registration mast bearing fit, said two are provided with angle between foot-operated.
Further, said riding comprises the pipe link that cooperates with axis, and is arranged on the pedal on the pipe link.
Further, said contiguous block is arranged on the axis with respect to the other end of chute.
Further, said eccentric wheel comprises and is positioned at the in-to-in tight pulley, and is arranged on the peripheral activity wheel of tight pulley; Said drive sprocket is affixed with movable wheel.
The bicycle driving device of the utility model, owing to be provided with eccentric wheel, said two are provided with angle between foot-operated; When wherein one when riding at vertical position; Another is ridden can be in obliquity, and laborsaving when stepping on, it had both kept foot-operated sense of motion consistent. to reduce kinetic energy rejection; Make foot-operated motion rapidly through little arm of force district again, can improve sport efficiency greatly.
Description of drawings
Fig. 1 is the block diagram of the utility model bicycle driving device.
The specific embodiment
In the present embodiment; With reference to shown in Figure 1, this bicycle driving device comprises and cycle chain ingear drive sprocket 1; And be arranged on the eccentric wheel 2 in the drive sprocket 1; And run through the axis 3 of eccentric wheel 2, and it is foot-operated 4 to be arranged on two of axis 3 two ends, and be used to connect wherein one foot-operated 4 with the contiguous block 5 of drive sprocket 1; Second registration mast 11 that said drive sprocket is provided with first registration mast 10 and is oppositely arranged with first registration mast 10, said contiguous block 5 are provided with first chute 50 with first registration mast, 10 bearing fits; Said second chute 51 that is provided with second registration mast, 11 bearing fits of riding is provided with angle between said two foot-operated 4.During motion, foot-operated 4 drive drive sprocket 1, the first registration mast 10 through contiguous block 5 moves in first chute 50, and second registration mast 11 moves in second chute 51, drives drive sprocket 1 and rotates.When wherein one when riding at vertical position, another foot-operated can be in obliquity, laborsaving when stepping on, it had both kept foot-operated sense of motion consistent. to reduce kinetic energy rejection; Make foot-operated motion rapidly through little arm of force district again, can improve sport efficiency greatly.Certainly, also can on contiguous block 5, slide post be set, drive sprocket 1 is provided with the chute with the slide post bearing fit, can reach same purpose.
Wherein, said foot-operated 4 comprise the pipe link 40 that cooperates with axis 3, and are arranged on the pedal 41 on the pipe link 40.Said contiguous block 5 is arranged on the axis 3 with respect to the other end of chute 50.Said eccentric wheel 2 comprises and is positioned at in-to-in tight pulley 20, and is arranged on the peripheral activities wheel 21 of tight pulley 20; Said drive sprocket 1 is affixed with activity wheel 21.Said axis 3 comprises overcoat, and is arranged on the interior cover in the overcoat, overcoat and foot-operated connection wherein, and interior cover and another are ridden and are connected.
The bicycle driving device of the utility model, owing to be provided with eccentric wheel, said two are provided with angle between foot-operated; When wherein one when riding at vertical position; Another is ridden can be in obliquity, and laborsaving when stepping on, it had both kept foot-operated sense of motion consistent. to reduce kinetic energy rejection; Make foot-operated motion rapidly through little arm of force district again, can improve sport efficiency greatly.
Below the utility model is done a detailed description; The above is merely the preferred embodiment of the utility model, when not limiting the utility model practical range; Be allly to do impartial change and modify, all should still belong in the utility model covering scope according to the application's scope.
