The invention relates to a bridge driving system. The bridge drive system includes: a motor housing including a first axial end and a second axial end; the motor cover is connected to the first axial end, and the motor cover and the motor shell are configured to jointly define a first cavity; a transmission housing connected to the second axial end, where the transmission housing and the motor housing are configured to collectively define a second cavity; and a cooling liquid storage unit located at the bottom of the bridge driving system and including: a first baffle plate disposed on a side of the motor cover facing the motor housing and forming a first slit between the first baffle plate and the first axial end; the second baffle is arranged on the side, away from the motor cover, of the motor shell, a second slit is formed between the bottoms of the motor shell, and the first baffle and the second baffle define a third cavity in the axial direction; and the first cavity is in fluid communication with the first cavity through the first slit and is in fluid communication with the first cavity and the second cavity through the second slit.
本发明涉及电桥驱动系统。电桥驱动系统包括:电动机壳体,包括第一轴向端和第二轴向端;电动机盖,其连接到第一轴向端,其中,电动机盖和电动机壳体构造成共同限定第一腔体;变速器壳体,其连接到第二轴向端,其中,变速器壳体和电动机壳体构造成共同限定第二腔体;和冷却液储液单元,其位于电桥驱动系统的底部并且包括:第一挡板,其设置在电动机盖的朝向电动机壳体的一侧上,并且与第一轴向端之间形成第一狭缝;和第二挡板,其设置在电动机壳体的远离电动机盖的一侧上,并且电动机壳体的底部之间形成第二狭缝,其中,第一挡板和第二挡板沿轴向限定第三腔体,其通过第一狭缝与第一腔体流体连通并且通过第二狭缝与第一腔体和第二腔体流体连通。
