An electric vehicle drive unit includes an inverter, a gear box, an electric motor coupled to the inverter and to the gear box, a cooling jacket, and coupled to the gear box, a main coolant inlet, a coolant outlet, and an external passive air bleed device. The cooling jacket has a cooling chamber and surrounds at least a portion of the electric motor. The main coolant inlet couples to the cooling jacket. The coolant outlet is located at a lower portion of the gear box. The external passive air bleed device runs between an upper portion of the cooling jacket and the coolant outlet. The inverter may couple to a first side of the gear box and the electric motor may couple to a second side of the gear box such that the inverter and the electric motor reside on opposite sides of the gear box.

Passive air bleed for improved cooling systems

A system that has electrically or electro-pneumatically actuated aerodynamic structures. An electric or electro-pneumatic actuator is employed, which receives signals from an existing anti-lock braking system (ABS) controller to determine when actuation occurs. Other systems are also provided that feature electric or electro-pneumatic actuation, including underbody skirts and scoops, as well as inflatable tractor-trailer gap sealing devices, adjustable tractor-trailer gap sealing flaps and inflatable trailer upper streamlining devices. Electronic control units (ECUs) for aerodynamic system control interfacing with alternate sensors for calculating speed are also provided. Satellite navigation, platooning awareness and managed pressure reserve capability can be employed with the aerodynamics ECU.
