A kind of rickshaw, gymnastic apparatus transmission gearshift, comprise and be arranged at the transmission shaft in the casing and be arranged at drive wheel on the transmission shaft, characteristics are that first, second, third transmission shaft coaxial line is arranged side by side, two ends are connected in casing, the first, the 3rd transmission shaft two ends wherein are movably connected on casing, are provided with power input device after casing is stretched out in the first transmission shaft end;
First drive wheel engagement on the power output wheel on first transmission shaft and second transmission shaft, the 3rd drive wheel on second drive wheel on second transmission shaft and the engagement of the 4th drive wheel on the 3rd transmission shaft or second transmission shaft and the engagement of the 5th drive wheel on the 3rd transmission shaft;
The lower end of gearshift is movably connected on the 4th, the 5th drive wheel, top stretch out casing and with its flexible connection, the upper end is provided with the gearshift spanner;
The end that described the 3rd transmission shaft stretches out casing is provided with the 6th drive wheel.The 6th drive wheel is sprocket wheel or belt pulley (being configured according to the needs that use vehicle or gymnastic apparatus).
The further improvement project of the utility model is, the 4th, the 5th drive wheel on the 3rd transmission shaft is a duplicate gear, and the connecting sleeve of between is provided with a ring recess mouth, and the lower end of gearshift is positioned at notch.
The utility model further improvement project is, the transverse section of described gearshift is the bar of circle or rectangle, and the lower end is 90 degree bendings, bending head and is and is horizontally disposed with, and its length is less than width of rebate.The gearshift spanner of gearshift is connected with Returnning spring.
The utility model further improvement project is, the 3rd transmission shaft transverse section is rectangle or is polygonal, the junction surface of the 4th, the 5th drive wheel and its coupling, and be Spielpassung with it.
The utility model compared with prior art has following obvious advantage:
The utility model adopts the mode of multiple sets of teeth wheel transmission, can carry out shift speed change by the gearshift spanner as required, realizes the branch of " soon " " slowly ", satisfies people's demand.Simultaneously, owing to adopt gear transmission mode, in gearshift is used, can not take place as falling the chain phenomenon in the sprocket driving.The utility model adopts " one " word formula arranging method, has reduced the power of existing angle loss during gears such as " triangles " is arranged, and has the labour-saving advantage.
The utility model can be used for bicycle, electric bicycle, tricycle for the disabled, and equipment such as fitness equipments.
