Pumbaa PMEA40000Z Central E-axle

• Parametric design calculations
• Dimension chain check analysis
• Transmission check analysis
• Tooth shape error study
  

Advantage 1: Layout space advantage

Dual motors, dual AMT gearboxes, active lubrication system, etc. are highly integrated; The external interface is simple, which is convenient for the whole vehicle layout;

Advantage 2: High efficiency and energy saving

Helical gears replace helical bevel gears, and the mechanical efficiency can reach 98%; Using high-efficiency oil-cooled motor and active lubrication system, the system efficiency can reach up to 93%;

The weight is significantly reduced, and the weight is reduced by more than 400Kg compared with the central pure electric drive system (double-axle structure);

Advantage 3: Control strategy advantage

Torque assist can realize power without interrupting gear shifting;

It can realize heavy-load ramp-up shifting and improve operational efficiency; Optimize the control strategy and improve driving comfort;
