Abstract
A variable-torque transmission capable of automatically regulating rotation speed is characterized in that the transmission can achieve continuous transmission by alternately driving a power output shaft through at least three groups of transmission mechanisms; a cross shaft fixed on a swing rod drives a transmission rope to pull a one-way clutch on the power output shaft to rotate so as to achieve stepless speed regulation in a large range; a torque regulating cam II fixed on the cross shaft of the swing rod is connected with a torque regulating cam I hinged on a bracket through a rope; a torque regulating wheel coaxially fixed on the torque regulating cam I is connected with a torque regulating spring fixed on the bracket through a pulling rope fastened on the torque regulating wheel in a hanging manner, so that the cross shaft changes along with the loads relative to the center distance of the power output shaft so as to acquire corresponding output torque. An engine using the variable-torque transmission has the advantages of stable operation, reliable operation, high efficiency, no flameout, and long service life. When the cross shaft is superposed with the central line of the power output shaft, the power output shaft stops to serve as a clutch so as to obviate the need of additional clutches, and the variable-torque transmission has the advantages of more reasonable structure, wide application, etc.
