Gearbox body with clutch function

Abstract

The utility model discloses a gear box body with a clutch function. An inner cavity of the gearbox body is transversely provided with an output shaft, and the surface of the output shaft is sequentially and fixedly sleeved with speed change mechanisms from right to left. Through the arrangement of the speed change mechanism, the output shaft can rotate to drive the planetary gear, the internal tooth gear, the second-gear synchronizer and the third-gear gear to rotate along with the output shaft, and then the second-gear synchronizer and the third-gear gear are pushed to move on the driven shaft by controlling the shifting fork to swing left and right. When the second-gear synchronizer moves to be meshed with the inner tooth gear to obtain power of the output shaft to drive the driven shaft to rotate along with the output shaft to transmit torque, similarly, when the second-gear synchronizer and the third-gear and fourth-gear synchronizer are not meshed with any gear of the output shaft to achieve power separation, the power of the output shaft cannot be transmitted to the driven shaft, and the driven shaft cannot rotate autonomously to achieve clutch idling.
