In the figure: 1 front wheel, 2 rear wheels, 3 steering handle, 4 pedal base, 5 gear box, 6 bevel gear, 7 left bevel gear, 8 right bevel gear, 9 left one-way clutch, 10 right one-way clutch, 11 big gear, 12 small gear, 13 rotating rod, 14 pedal, 15 rotating shaft, 16 transmission shaft.

Detailed Description

The invention will be further described with reference to the following drawings and specific embodiments:

as shown in fig. 1 to 4, a pedal bicycle includes a front wheel 1, a rear wheel 2, pedals to which a rotation shaft 15 is connected, and a driving structure including a gear pair connected to the rotation shaft 15, a transmission shaft 16 connected to the gear pair, and a driving gear group connected to the transmission shaft 16; the driving gear set comprises a bevel gear 6, a left bevel gear 7 and a right bevel gear 8 which are meshed with the bevel gear 6, the bevel gear 6 is coaxially connected to the rear wheel 2, one-way clutches are arranged at the axle centers of the left bevel gear 7 and the right bevel gear 8, the one-way clutches are connected with the transmission shaft 16, and the directions of the two one-way clutches, which can control rotation, are opposite.

Specifically, the frame structure of the pedal bicycle is integrally formed, and the pedal bicycle further comprises a steering handle 3, a pedal base 4 and a gear box 5 so as to form a finished bicycle structure; wherein, the gear pair is installed in the gear box 5, and the axis of rotation 15 rotationally connects on the running-board base 4, and running-board base 4 and gear box 5 fixed connection, gear box 5 and the frame fixed connection of rear wheel 2. The running-board is including connecting dwang 13 on axis of rotation 15 and being used for trampling and two footboard 14 of level setting, footboard 14 fixed connection is at the both ends of dwang 13, footboard 14 sets up with dwang 13 symmetry axis of rotation 15 to make both feet conveniently trample.

As shown in fig. 2, the gear pair includes a gearwheel 11 and a pinion 12 engaged with the gearwheel 11, the axis of the gearwheel 11 is connected with a rotating shaft 15, and the axis of the pinion 12 is connected with a transmission shaft 16; when the two pedals 14 are stepped on, the rotating shaft 15 is driven to rotate clockwise and anticlockwise alternately, so that the large gear 11 drives the small gear 12 to rotate, and the transmission shaft 16 is driven to rotate clockwise and anticlockwise alternately through the output of the small gear 12. The pedal bicycles of different speeds are set by setting the gear ratio of the large gear 11 and the small gear 12 to control the number of output revolutions of the small gear 12.

As shown in fig. 3, the axes of the left bevel gear 7 and the right bevel gear 8 are respectively provided with a left one-way clutch 9 and a right one-way clutch 10, the left one-way clutch 9 and the right one-way clutch 10 are both connected with a transmission shaft 16, and the bevel gears 6 are both meshed with the left bevel gear 7 and the right bevel gear 8. Specifically, when the transmission shaft 16 rotates counterclockwise, the transmission shaft 16 is locked with the left one-way clutch 9 and unlocked with the right one-way clutch 10, so that the transmission shaft 16 drives the left bevel gear 7 to rotate counterclockwise and further drives the bevel gear 6 to rotate clockwise, thereby driving the rear wheel 2 to rotate clockwise to advance the pedal bicycle; when the transmission shaft 16 rotates clockwise, see fig. 4, the transmission shaft 16 is locked with the right one-way clutch 10 and unlocked with the left one-way clutch 9, so that the transmission shaft 16 drives the right bevel gear 8 to rotate clockwise, which in turn drives the bevel gear 6 to rotate clockwise, to drive the rear wheel 2 to rotate clockwise, so as to advance the pedal bicycle.

When the bicycle is used, two feet step on the pedals 14, and the pedals are alternately stepped up and down with force, so that the rotating shaft 15 alternately rotates clockwise and anticlockwise, and the bicycle is driven to advance under the action of the gear pair and the gear set.
