Novel electric axle assembly

Abstract

The invention discloses a novel electric axle assembly which comprises a transversely-placed drive motor and a hollow motor power output shaft. The left end of the motor power output shaft protrudes out of the left side wall of the drive motor, and the right end of the motor power output shaft is arranged in the drive motor. The inner portion of the left end of the motor power output shaft is fixedly connected with a differential mechanism. The power output ends on the left side and the right side of the differential mechanism are connected with a first axle shaft and a second axle shaft. Theleft end of the first axle shaft is fixedly connected with a planetary reducer, and the second axle shaft transversely penetrates through the motor power output shaft to be fixedly connected with a planetary reducer. A planetary reducer planet carrier of each planetary reducer is connected with a wheel. The novel electric axle assembly is excellent in performance, the length of a transmission chain of an electric automobile assembly can be remarkably shortened, the transmission efficiency of the electric automobile assembly is improved, transmission efficiency losses are reduced, and the passenger capacity and the endurance mileage of an electric automobile are effectively increased.

Description

technical field [0001] The invention relates to the technical field of electric vehicle manufacturing, in particular to a novel electric axle assembly. Background technique [0002] At present, electric vehicles are the development direction of traditional energy vehicles because of their advantages such as energy saving and environmental protection, compact structure, and small mass-to-volume ratio. They have been widely used in people's work and life. Increasingly demanding. [0003] Electric vehicles are currently developing rapidly, and their battery life has always been the focus of users' concern. At present, everyone's main concern is mainly focused on batteries, because the capacity and power density of batteries are the main determinants of vehicle battery life. At the same time, at present, the powertrain of electric vehicles generally adopts the traditional internal combustion engine vehicle power transmission structure, specifically: the motor is arranged in the...

Problems solved by technology

Therefore, in this design, the transmission chain of the electric vehicle assembly is relatively long, which leads to a large loss of transmission efficiency, low transmission efficiency, and greatly reduces the space utilization of the vehicle chassis, which cannot achieve the powertrain of the electric vehicle. The light weight and the maximization of battery layout space increase the energy consumption per unit load of electric vehicles, which ultimately seriously affects the passenger capacity and cruising range of electric vehicles.
