The invention discloses a high-speed-ratio stepless speed change unit. The high-speed-ratio stepless speed change unit is characterized in that an input shaft is embedded into a bearing hole in the inner wall of a speed changing box through shaft shoulders at the two ends of the shaft to be fixed, and a driving wheel is fixed to the input shaft; a variable torque adjusting mechanism built-in linear motor is connected to a radial spoke guide rail of a driving wheel in a sleeving manner; a control signal is transmitted to the variable torque adjusting mechanism built-in linear motor through a sliding ring, and a variable torque adjusting mechanism is controlled to move along the radial spoke guide rail; a crank of a slider-crank mechanism is connected with the variable torque adjusting mechanism through a knuckle bearing; the crank and a slider of the slider-crank mechanism are connected through a knuckle bearing; the slider of the slider-crank mechanism is connected with a rack of a driving rack set; a gear in
