1. An integrated drive system, comprising:
an electric machine having a housing and an output shaft;
a planetary gear transmission mechanism having a first-stage planetary gear mechanism and a second-stage planetary gear mechanism configured such that torque is distributed across the first-and second-stage planetary gear mechanisms; and
a wheel comprising a rim and a cover plate that is fixedly connected to the rim,
wherein the first-stage planetary gear mechanism is configured to output a first output torque that is transmitted to the wheel and a second output torque that is transmitted to the second-stage planetary gear mechanism,
wherein the second-stage planetary gear mechanism is configured to output a third output torque that is transmitted to the wheel,
wherein the planetary gear transmission mechanism is mounted in a space enclosed by the rim, and
wherein a brake disk is mounted on a side of the cover plate facing toward the electric machine.
