The invention belongs to the technical field of vehicle driving, and particularly relates to an anti-explosion coaxial integrated electric drive axle which comprises a double-output-shaft motor, a cavity is formed in the center of a motor rotor of the double-output-shaft motor, an intermediate shaft is arranged in the cavity in a penetrating mode, and the intermediate shaft is not in contact with the inner wall of the cavity; the left end of the motor rotor is connected with the differential, a left half axle gear of the differential is fixedly connected with the left connecting shaft, a right half axle gear of the differential is fixedly connected with the intermediate shaft, the right end of the intermediate shaft is fixedly connected with the right connecting shaft through the right brake gear ring, and the parking brake friction plate is slidably mounted on the outer side of the right end of the motor rotor through a spline. According to the electric drive axle, the motor rotor with the cavity is adopted, the left connecting shaft, the motor rotor and the right connecting shaft are designed to be coaxial through the middle shaft, the occupied space of the electric drive axle is greatly reduced, the transmission stage number is reduced, and the transmission efficiency is greatly improved. Meanwhile, due to the fact that the integration level of the electric drive axle is high, the structural design of the chassis is simple, and the electric drive axle is convenient to install.
本发明属于车辆驱动技术领域,具体涉及一种防爆同轴式集成电驱桥,包括双输出轴电机,双输出轴电机的电机转子的中心具有空腔,空腔内穿设有中间轴,中间轴与空腔的内壁不接触;电机转子的左端连接差速器,差速器的左半轴齿轮固定连接左连接轴,差速器的右半轴齿轮固定连接中间轴,中间轴的右端通过右制动齿圈固定连接右连接轴,电机转子的右端的外侧通过花键滑动安装有驻车制动摩擦片。本发明通过采用具有空腔的电机转子,利用中间轴将左连接轴、电机转子和右连接轴设计成为同轴,大大减小了电驱桥的占用空间,减少了传动级数,大大提升了传动效率。同时因为电驱桥集成度高,使得底盘的结构设计也较简单,电驱桥安装方便。
