A modular hybrid transmission provides improved support of a rotor and an improved cooling layout for a stator. The modular hybrid transmission has a rotating assembly and a housing assembly. The rotary assembly includes a rotor assembly, a rotor-carrying hub supporting the rotor, and an input shaft. A rotor carrier hub is rotationally fixed to the input shaft. The housing assembly accommodates the rotating assembly and includes a housing having an outer wall, a stator assembly connected to the outer wall, and a radially extending fixed wall extending from the outer wall toward the output shaft. The fixed wall includes an axially extending wall portion extending parallel to an outer surface of the input shaft, and the radial ball bearing supports the input shaft on the axially extending wall portion. The two stator cooling paths form a channel in the housing.

    一种模块化混合传动装置,其提供了对转子的改善的支撑以及提供了用于定子的改善的冷却布局结构。该模块化混合传动装置具有旋转组件和壳体组件。旋转组件包括转子组件、支撑转子的转子承载毂、和输入轴。转子承载毂旋转地固定在输入轴上。壳体组件容纳旋转组件,并且包括具有外壁的壳体、连接至外壁的定子组件、以及从外壁朝向输出轴延伸的径向延伸的固定壁。固定壁包括平行于输入轴的外表面延伸的轴向延伸的壁部分,并且径向滚珠轴承将输入轴支撑在该轴向延伸的壁部分上。两个定子冷却路径在壳体中形成通道。
