Abstract
The present invention discloses a drive rear axle of an electric vehicle, relates to the field of accessories of electric vehicles, and especially relates to a drive rear axle of an electric vehicle. The drive rear axle of the electric vehicle adopts a transmission structure of a motor, a first speed reducer and a differential. The motor is arranged in a way of being perpendicular to the semiaxis of the electric vehicle, and driving and driven gears of the first speed reducer are formed by cold extrusion processing, the motor and the differential are connected through the first speed reducer, and the first speed reducer is closer to the center of gravity of the differential, so that the transmission effect is more stable. According to the drive rear axle of the electric vehicle, the transmission chain is shortened, the transmission efficiency is improved, the structure is more compact, the drive rear axle of the electric vehicle can be directly applied to electric vehicles after the product is formed, the power of the motor is fully utilized on the premise of guaranteeing the traffic safety, and the energy conservation and environmental protection effects are achieved.
Description
Technical field
