The invention relates to the technical field of traction machines, in particular to a traction machine which comprises a transmission mechanism, a traction wheel and a brake wheel, the transmission mechanism is arranged in the radial range of the brake wheel and comprises an input shaft, an output shaft and a transmission module, and the output shaft is connected with the traction wheel; the transmission module comprises an input gear arranged on the input shaft; the output gear is arranged on the output shaft; the reduction gear set comprises a first-stage gear, a transmission shaft and a second-stage gear, the first-stage gear and the second-stage gear are both arranged on the transmission shaft and synchronously rotate with the transmission shaft, and the first-stage gear is in external meshing transmission with the input gear; the secondary gear is in external meshing transmission with the output gear, and the input shaft and the output shaft are arranged on the same side of the transmission shaft. The two-stage gear transmission structure is adopted, the transmission efficiency is improved, the reduction gear set is arranged on the same side of the input shaft and the output shaft, the space in the radial direction of the brake wheel is effectively shortened, and the high-speed and small-sized improvement of the traction machine is achieved.
