Problems solved by technology

Similar improvements in the prior art also include that they only take some labor-saving and speed-up measures to overcome the dead angle of pedal rotation or the speed ratio between the pedal and the wheel, but the labor-saving effect is not good.

Embodiment Construction

[0027] like figure 2 , 3 , 4, 5, 6, 7, 8, a power saver for transmission machinery, a power saver is installed between the driving wheel 1 and the driven wheel 2, and its structure is as follows: the driving wheel 1 drives a support The driving shaft 4 on the power saver box 3 and the vertical driving shaft 4 are provided with 10 pressure bars 5 that are evenly distributed along the axial direction and have equal horizontal angles, and a lever 6 is arranged horizontally corresponding to the pressure bars 5. The fulcrum 7 of the lever 6 Fixed on the labor saver box 3, the end of the power arm 6.1 of each lever is driven downward by the pressure bar, and the end of the resistance arm 6.2 of each lever is hinged upward with a sliding link 8, each sliding link 8 Through a driving member 9 , corresponding to the position of each pressure lever 5 , it is respectively connected to the driven shaft 10 , and the driven shaft 10 is supported on the power saver box 3 . The pressure le...

Abstract

A labour economizer which is designed based on the lever principle sets driving shaft built by a couple of pressure lever at motive force arm end of lever and sets driven shaft built by a couple of driving structural component at drag force arm end of lever. In the course of one cycle rotation of the driving and driven shafts, each sliding side rod can only push the driven shaft for one angle rotation so that the labour economizer will achieve the optimum effect of labour economizing when the rotary radius formed by the pressure lever and formed by the driving component is the same. To set it on the rickshaw, it will save mush more manpower than the rickshaw set with the economizer in existing technique under the same speed ratio.

Description

Technical field: [0001] The invention relates to a labor-saving device for transmission machinery, which is especially suitable for the transmission device of wheeled vehicles driven by human power. technical background: [0002] Ordinary bicycles, tricycles, four-wheeled vehicles, disabled vehicles and other human-driven machinery, the transmission device is to rely on left and right pedals or manual wheels to drive the wheel, and drive the flywheel coaxial with the wheel through the chain, so that the vehicle can run. The transmission device of the rickshaw makes the rider feel very free, especially in the case of a large speed ratio, so the speed is slower. The labor-saving solution in the prior art, such as c N2146423Y, discloses a labor-saving bicycle, which is aimed at the left and right pedals on the same plane. A ratchet wheel is installed between the central shaft and the pedal, and a coordinated swing device is installed between the pedal and the frame, so as to o...
