    • An electric drive unit includes an electronic control and monitoring module integrally connected to an electric motor. The housing of the electric motor has a double-walled construction to form a water jacket with cooling water passages therein. The electronic module includes at least one high power component that requires cooling. This component is mounted directly on a cooling insert that extends through a recess in the electronic module housing and is inserted in an opening provided in the outer wall of the motor housing. In this manner, the cooling insert is integrated into the water jacket of the motor housing and is directly cooled by the cooling water flowing in the cooling passages. A very compact and reliable construction is achieved, in which the electric motor and the electronic module share a common water cooling circuit. External water hoses and external electrical connections between the electric motor and the electronic module are avoided.
    • 电驱动单元包括与电动机一体连接的电子控制和监视模块。 电动机的壳体具有双层结构,以形成其中具有冷却水通道的水套。 电子模块包括至少一个需要冷却的大功率部件。 该部件直接安装在延伸穿过电子模块壳体中的凹部的冷却插入件上,并插入设置在电动机壳体的外壁中的开口中。 以这种方式,冷却插入件集成到电动机壳体的水套中,并且通过在冷却通道中流动的冷却水直接冷却。 实现了非常紧凑和可靠的结构,其中电动机和电子模块共享公共的水冷却回路。 避免了电动马达与电子模块之间的外部水软管和外部电气连接。
