Problems solved by technology

[0002] Bicycles need more torque when accelerating. However, the existing bicycles all have a fixed transmission ratio structure. In order to take into account both high and low speeds, the transmission ratio of the active and passive sprockets of ordinary bicycles is 2, and the minimum transmission ratio of the active and passive sprockets of mountain bikes is only 2. is 0.69, under the condition of limited pedaling force, the obtained driving torque is also very limited, and it needs to be realized by manipulating the transmission mechanism, so that the acceleration of the bicycle is limited to a certain extent

Embodiment Construction

[0021] Such as figure 1 As shown, the one-way wheel 2 that is provided with teeth is installed on the wheel (not shown), and one end of the return spring 3 is connected with the vehicle frame (not shown), and the other end is connected with the chain 1, and the chain 1 is bypassed The toothed one-way wheel 2 is connected to the vehicle frame after extending a distance to the vehicle frame. One end of the rocker arm 4 is provided with a foot pedal 5 hinged thereto, and the other end is provided with a force-applying wheel 6, the middle of which is hinged with the vehicle frame. , The applying force wheel 6 is in contact with the chain 1, and now the pedal 5 is in the initial state of not being stepped on.

[0022] Such as figure 2 As shown, the one-way wheel 2 that is provided with teeth is installed on the wheel (not shown), and one end of the return spring 3 is connected with the vehicle frame (not shown), and the other end is connected with the chain 1, and the chain 1 is ...

Abstract

The invention discloses a giant force bicycle. The bicycle comprises a frame, traction belts driving one-way wheels to rotate are arranged on the left side and the right side of each wheel respectively, one end of each traction belt is connected with a return spring fixed to the frame, the middle of each traction belt bypasses the corresponding one-way wheel to extend towards the frame by a certain distance and then is connected with the frame, and pedaling force is applied to a certain point of an extending section of each traction belt. The transmission ratio of a pedal is gradually increased from zero along with the increase of the stroke, and a huge traction force is obtained for the one-way wheel at the initial stage of treading.

Description

technical field [0001] The invention relates to the technical field of human-powered bicycles, in particular to a Juli bicycle. Background technique [0002] Bicycles need more torque when accelerating. However, the existing bicycles all have a fixed transmission ratio structure. In order to take into account both high and low speeds, the transmission ratio of the active and passive sprockets of ordinary bicycles is 2, and the minimum transmission ratio of the active and passive sprockets of mountain bikes is only 2. is 0.69, under the condition of limited pedaling force, the obtained driving torque is also very limited, and it needs to be realized by manipulating the speed change mechanism, so that the acceleration of the bicycle is limited to a certain extent. Contents of the invention [0003] In order to solve the above problems, the present invention discloses a Juli bicycle, the transmission ratio of which gradually increases from zero during a pedaling stroke, and t...
