Abstract

The invention discloses a continuous power infinitely variable speed transmission mechanism, which comprises a reverse synchronous gear and a positive synchronous gear which are respectively in gear engagement with a power keeping input shaft, a first planetary gear train and a second planetary gear train which are connected through a speed-regulating power input shaft, and a transmission gear engaged with an output shaft keeping gear, wherein a bidirectional synchronizing clutch is arranged between the reverse synchronous gear and the positive synchronous gear and is connected to the second planetary gear train through the clutch; and the transmission gear is connected with the first planetary gear train through an output switching clutch and is connected with the second planetary gear train through a second internal gear. The full-range infinitely variable speed of the output shaft from the reverse maximum speed to the positive maximum speed can be realized by means of the speed change of the speed-regulating power input shaft and the engagement and disengagement of the clutch only under the condition that the rotating speed and the rotating direction of the power keeping input shaft, the output speed is stably changed and no power is interrupted in the whole process. The variable speed in the reverse direction is performed in the same mode.

Description

technical field [0001] The invention relates to a transmission mechanism, in particular to a continuous power continuously variable transmission mechanism for wheeled machinery. Background technique [0002] The characteristic of gear transmission is that the transmission ratio is fixed. If the output element has a relatively large speed range, it is often necessary to design a gearbox with multiple transmission ratios. When the gears are switched, due to the asynchronous speed of the components, the two gears cannot transmit power at the same time, and need to be disengaged first and then engaged, resulting in the interruption of the output power. Also due to the speed out of sync, shifting gears will cause a mechanical shock. If the shock is reduced, more transmission ratios are required, which will make the control more complicated. [0003] In wheeled machinery, hydraulic torque converters and manual shift gearboxes are currently used as travel speed control devices. A...
