Problems solved by technology

In practical applications, the force of the soles of the cyclist's feet always falls on the pedal shaft, driving the sprocket to rotate. During the working process, the length of the power rocker arm cannot be changed to obtain different power, so for the cyclist Said that the operation is heavy, consumes a lot of physical energy, and is prone to fatigue

Embodiment Construction

[0011] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0012] see figure 1 , a multi-stage variable force bicycle has a rocking arm 1, one end of the rocking arm 1 is connected with an intermediate shaft, and a pedal shaft 2 is installed at the other end of the rocking arm 1. One-way transmission device 4 is housed on pedal shaft 2, links with pedal 3 through one-way transmission device 4. The front of the above-mentioned pedal 3 is wider than the rear. The above-mentioned one-way transmission device 4 is a one-way bearing transmission device or a ratchet transmission device. Above-mentioned one-way transmission device 4 is left and right two groups of structures, and its structure is identical, and direction is opposite. The power rocker arm 1 on both sides of the bicycle is set relatively 180 degrees, and when one of the pedals 3 was in the high position, the other pedal 3 was in the low position. Whe...

Abstract

The invention relates to a multi-level inotropic bicycle. One end of a rocker is connected with a middle shaft, the other end of the rocker is provided with a pedal shaft which is provided with a one-way transmission device and connected with a pedal through the one-way transmission device, and power rockers at both sides of the middle shaft of the bicycle are arranged at an opposite angle of 180 degrees. When the soles of a rider forwards tread the pedals in a high position at any angle or height, linkage between either pedal shaft and either rocker can be locked under the action of the one-way transmission device, and the length of a force arm is the addition of the length of the rocker and the front width of either pedal so as to save labor. A stretching device is arranged in front of either pedal, and linkage between a pedal shaft and a rocker is unlocked when the pedal reaches the position so that the pedal can backwards rotate around the pedal shaft. The invention has the advantages of simple structure, easy manufacture, reliable operation, easy control, low physical agility consumption and obvious labor-saving effect and is suitable for use on various bicycles and relative machinery.

Description

technical field [0001] The invention relates to a transmission mechanism, in particular to a multi-stage variable-force bicycle which adopts a one-way transmission device between a bicycle pedal shaft and a pedal. Background technique [0002] Existing bicycle product, its pedal power transmission mechanism is made up of the central shaft of bicycle and the rocking arm that is contained on the central shaft two ends, pedal axle, pedal. The connection between the rocker arm, the center shaft and the pedal shaft is a rigid connection; the connection between the pedal shaft and the pedal is a live connection. This type of pedal can freely rotate 360 ​​degrees around the pedal shaft. The length of the moment arm of this type of power rocker arm is also fixed. In practical applications, the force of the soles of the cyclist's feet always falls on the pedal shaft, driving the sprocket to rotate. During the working process, the length of the power rocker arm cannot be changed to o...
