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
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);
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;
