Introduction of continuously variable mechanism

　　A continuously variable mechanical device is a transmission device.In the first embodiment, the input shaft and the output shaft are mounted on a common shaft and can rotate relative to each other, a plurality of idlers mesh with gears on the output shaft, and each idler is connected to the output through a connecting rod and a unidirectional gear brake. The swing plate on the shaft is associated.

　　In the second embodiment, the power can be directly transmitted from the input shaft to the output shaft, or can be transmitted through a predetermined low speed ratio mechanism or a hydraulic torque converter (which can continuously change the speed ratio from XNUMX to the low speed ratio) .The torque converter utilizes the interaction of the retractable pawl and the static pressure to make the torque change automatically in response to the load of the output shaft, or change with the change of the input shaft speed.

　　A frame mounted on the second rod and fixedly connected to it; a pin shaft mounted on the frame, which is perpendicular to the second rod and maintains a certain distance, the above-mentioned pin shaft is set perpendicular to the third shaft In the plane, its center line is transverse to the second helical gear; the third helical gear is rotatably mounted on the pin shaft and meshes with the outer circumference of the second helical gear; a rotating mechanism connected to the frame makes it The frame on the second rod rotates.
