An electric ATV motor integrated rear axle comprises a left rear axle cylinder and a right rear axle cylinder. A differential motor is connected between the left rear axle cylinder and the right rear axle cylinder, a left semi-shaft is arranged in the left rear axle cylinder, a left
disc brake is mounted on the left rear axle cylinder, the left
disc brake is provided with a left
disc brake plate in a matched mode, a right semi-shaft is arranged in the right rear axle cylinder, a right disc
brake is mounted on the right rear axle cylinder, and a right disc
brake plate is arranged on the right disc
brake in a matched mode. The electric ATV motor integrated rear axle has the beneficial effects that a
power unit, a reducing mechanism, a differential mechanism, a transmission mechanism and a braking mechanism are integrated to be a whole, transmission components such as a chain, a chain wheel, a chain wheel seat and a transitional transmission gear shaft are omitted, the torque is increased, the transmission moment force is large, transmission is smooth and steady, the transmission
friction loss is greatly reduced, the output
power loss is small, the service life is long, and maintenance is convenient; and during turning of an electric ATV, through differential transforming of the differential motor, safe, reliable and stable steering is ensured.
