Embodiment Construction

[0014] exist figure 2 The medium-use transmission chain (6) connects the pinion gear (3) at the left end of the universal joint shaft and the large gear (1) on the left pedal shaft, and on the same straight line, fixes the fixed frame (4) between the universal joint shaft and the large frame ), and fix the left end of the cardan shaft.

[0015] exist image 3 Middle use drive chain (4), connect cardan shaft right end pinion (2), and front wheel pinion (3), on the same straight line. With transmission chain (8), connect pedal shaft right large gear (1), and rear wheel pinion (7), on the same straight line. Fix the pinion at the right end of the universal joint shaft and the fixed mount (5) of the semicircular structure, and fix the right end of the universal joint shaft.

[0016] Structural success statement

[0017] When turning the pedal shaft, the large gear on the right side of the pedal shaft drives the rear wheel to rotate through the chain. The large gear on the le...

Abstract

The invention belongs to traffic tools for riding instead of walking. The problem how to change a single-wheel stress type bicycle into a double-wheel stress type double-wheel bicycle is solved; small gears of the same type are arranged on a front wheel, a rear wheel, the left end of a universal shaft and the right end of the universal shaft; large gears of the same type are arranged on the left face and the right face of a pedal shaft; a semicircular structure is formed between a front wheel fork and a directional cylinder; the universal shaft is arranged in the semicircular structure; the middle folding point of the universal shaft and the central point of the directional cylinder are arranged on the same straight line; the small gear at the right end of the universal shaft and the small gear on the front wheel are connected to the same straight line through a transmission chain; the small gear at the left end of the universal shaft and the large gear on the left face of the pedal shaft are connected to the same straight line through a transmission chain; and the large gear on the right face of the pedal shaft and the small gear on the rear wheel are connected to the same straight line. The left end of the universal shaft is fixed to a bicycle frame; the right end of the universal shaft is fixed to the front wheel fork and the directional cylinder and rotates within the direction range; if the direction is changed, the shape of the universal shaft is changed accordingly, but force across the universal shaft cannot be changed. Therefore, the double-wheel stress type two-wheel bicycle is formed.

Description

technical field [0001] The invention belongs to a vehicle for walking instead of walking. Background technique [0002] At present, the known bicycles are all rear wheels bearing force, and only the rear wheel can bear the force. In this single force bearing type bicycle, only the rear wheel is driven by the driving force transmitted by the chain to become the driving wheel. The front wheel cannot be driven by the chain, it only becomes a drag wheel. In this way, not only the riding speed is slow, but once the chain is broken, it will not work normally, which causes a lot of inconvenience. Contents of the invention [0003] In order to overcome the shortcomings of the existing single-wheel force-bearing bicycles that are slow in speed and unable to work normally when the chain is broken, the present invention provides a two-wheel force-bearing two-wheel bicycle, which not only overcomes the slow speed, but also increases the speed. , and when one chain is broken, the oth...
