Problems solved by technology

[0002] Mechanical stepped transmissions for automobiles have disadvantages such as interruption of power transmission when shifting gears, additional impact force on the drive train, changes in driving resistance directly changing the working conditions of the engine, and the need to separate and engage the clutch every time shifting gears, thereby increasing Reduce the labor intensity of the driver and reduce the service life of the engine and drive train parts
Cars equipped with automotive mechanical continuously variable transmission not only save fuel but also have good acceleration performance, but they are all directly driven by friction, and there are limitations on friction coefficient and unit pressure of parts, so they cannot transmit large power. The transmission efficiency and working reliability cannot meet the requirements of automobile performance, so it is limited to use in miniature automobiles with small displacement.

Embodiment Construction

[0011] please see figure 1 - Fig. 6, each component and the connection relationship among them have been as above. The power is input by the power input shaft 1, through the intermediate gear 2, the driving sprocket 3, the transmission chain 4, and the driven sprocket 5 drives the outer meshing planetary sprocket 6 coupled with it to rotate around the variable radius wheel 7, thereby pushing the movable The variable radius rotating arm 8 and the integrated power output shaft connected with it rotate so as to output power. The speed and torque at which the outer meshing planetary sprocket 6 rotates around the variable radius wheel 7 and the variable radius rotating arm 8 and the power output shaft rotate for a week are related to the radius of the variable radius wheel 7 at that time. When the variable radius wheel 7 is at the maximum radius, the outer meshing planetary sprocket 6 has the longest circumference around it, and is at the two ends of the variable radius arm 8. At ...

Abstract

The mechanical meshing transmission stepless speed variator is for vehicle use. The stepless speed variator includes power input shaft, chain wheel transmission part connected with the input shaft via intermediate gear, outer meshed planetary chain wheel controlled by the driven chain wheel, variable-radius rotating arm connected integrally with the power output shaft, variable-radius chain meshed to the outer meshed planetary chain wheel, variable-radius wheel internally connected to the variable-radius chain and rotating around the outer meshed planetary chain wheel, roller wheel fixed on the variable-radius rotating arm, hydraulic servo part inside the variable-radius rotating arm to make the outer meshed planetary chain wheel mesh with the variable-radius chain, radially moving chainwheel with overrunning clutch, and elastic sliding block-guide rail mechanism. It has the advantages of great transmission moment, high transmission efficiency and reliable, etc.
