Electric ATV motor integrated rear axle

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of motorcycles, in particular to an electric ATV motor integrated rear axle. Background technique [0002] At present, the commercially available electric ATV transmission system is that the electric motor is assembled on the ATV car body. The power of the electric motor drives the small sprocket output through the power output shaft, and then is transmitted to the rear axle of the ATV through the reduction mechanism composed of the small sprocket, chain, and large sprocket. , thus driving the ATV wheel to rotate. The above mechanism has the following disadvantages: through the secondary speed change, it is necessary to increase the sprocket, chain, and other transmission components to drive the rear wheel spindle, the manufacturing cost is high, the friction loss of parts is large during the transmission process, and the transmission chain is easy to fall off from the sprocket. The loss of output dynamic r...
