The invention discloses a variable-mode electric drive axle using a bidirectional transmission electromagnetic clutch, which comprises a drive motor I, a drive motor II, a left half shaft I, a right half shaft I, a spur gear differential mechanism, a first-stage speed reducer I, a first-stage speed reducer II, a second-stage speed reducer I, a second-stage speed reducer II, a mode switching actuator I and a mode switching actuator II, and a one-way clutch I, a one-way clutch II and the like. A driving part of the mode switching actuator I is connected with the output end of the first-stage speed reducer I, a first driven part is connected with the left half shaft I, and a second driven part is connected with the input end of the second-stage speed reducer I; and the connection condition of the mode switching actuator II is symmetrical to that of the mode switching actuator I. By controlling the working states of the mode switching actuator I and the mode switching actuator II, the variable-mode electric drive axle using the two-way transmission electromagnetic clutch can be switched among a distributed drive mode, a centralized drive mode and a fault-tolerant drive mode when a single-side motor breaks down.
本发明公开了一种使用双向传递电磁离合器的变模式电动驱动桥,包括:驱动电机Ⅰ,驱动电机Ⅱ,左Ⅰ半轴,右Ⅰ半轴,正齿轮差速器,一级减速器Ⅰ,一级减速器Ⅱ,二级减速器Ⅰ,二级减速器Ⅱ,模式切换执行器Ⅰ,模式切换执行器Ⅱ,单向离合器Ⅰ,单向离合器Ⅱ等。模式切换执行器Ⅰ的主动部分与一级减速器Ⅰ输出端相连接,第一从动部分与左Ⅰ半轴相连接,第二从动部分与二级减速器Ⅰ输入端相连接。模式切换执行器Ⅱ的连接情况与模式切换执行器Ⅰ相对称。通过控制模式切换执行器Ⅰ、模式切换执行器Ⅱ工作状态,能使所述使用双向传递电磁离合器的变模式电动驱动桥在分布式驱动模式、集中式驱动模式和单侧电机故障时的容错驱动模式三种模式间切换。
