Detailed Description

The technical scheme of the present invention is further described in non-limiting detail below with reference to the examples and the accompanying drawings.

The bicycle for driving the running gear by reciprocating the boom by the rope-driven movable pulley according to the present invention as shown in fig. 1 to 4 mainly comprises: wheels (1, 7); a frame (2); a main drive sprocket (3); chains (6, 10, 13, 33, 37, 63, 78); a gear box (9, 31); bevel gears (15, 16, 24, 26, 38, 41, 44, 45); a swing lever bracket (20); a power transmission shaft (21); swing levers (22, 23); movable pulleys (28, 30, 49, 50); swing lever ratchet shafts (42, 47); rear swing lever ratchet sleeves (43, 46); a rear power transmission shaft (48); fixed pulleys (53, 69); a traction rope (54, 56, 57, 70, 71, 72); intermittent winches (59, 60, 75, 76); a rear collision stopper (64); a winch shaft (73); a front small sprocket (74); front pawl impact blocks (8, 80);

the movable pulleys (28, 30, 49, 50) are arranged on movable pulley brackets (8, 29) fixed at the lower ends of the swing levers (22, 23), and the use of the movable pulleys saves half of driving force, so that a rider feels easier in the riding process.

The traction ropes (54, 56, 57, 70, 71, 72) pull the movable pulleys (28, 30, 49, 50) at the lower ends of the swinging levers (22, 23) to swing around the lever swinging shafts (25), and the generated torque is a value obtained by multiplying the traction force of the traction ropes by the length of the swinging shafts from the lower ends to the upper ends of the swinging levers, and the longer the length of the swinging shafts from the lower ends to the upper ends of the swinging levers is, the larger the value is.

The change value is that the length of the swinging lever is adjustable according to the requirement of a user, the diameter of the bevel gears (24, 26, 44, 45) arranged on the top swinging shaft (25) is not changed, and the product value of the traction force of the traction rope multiplied by the value of the length of the swinging shaft from the lower end to the top of the swinging lever is far larger than the reverse moment generated when the wheel running resistance is reversely pushed to the meshing of the bevel gears (26, 45) arranged on the swinging shaft (25) and the bevel gears (24, 44), so that the rear wheel (7) obtains huge driving torque.

The bicycle is provided with a set of speed increasing mechanism which consists of a series of chain wheels, chains, a speed changing mechanism and cone pulleys, and when the bicycle runs on a flat road surface and needs to run at high speed, the speed increasing mechanism is realized by changing the corresponding chain transmission of the speed changing mechanism. When the vehicle is running on a sloping road or an uneven road surface and needs to run normally, the vehicle can still be realized by changing the corresponding chain transmission of the speed change mechanism.

The movable lever ratchet shafts (42, 47) and the swing lever ratchet sleeves (43, 46) arranged at the upper ends of the swing levers (22, 23) only play a role in unidirectional transmission, when the swing levers (22, 23) swing from front to back, the pawls stir the lever swinging shafts (25) to rotate, when the swing levers (22, 23) swing from back to front, the pawls do not stir the lever swinging shafts (25) to rotate, and therefore stirring force generated by reciprocating swing of the swing levers (22, 23) stirs the lever swinging shafts (25) to rotate in one direction only.

The swinging directions of the two swinging levers (22, 23) are alternately performed, wherein when one swings from front to back, the other swings from back to front, so that the lever swinging shaft (25) can always rotate in one direction.
