Too big advantage is not accounted for compared with electric-machine directly-driven technology in property.
Although 3, the technical solution that motor is combined with AMT speed changers is solving climbing and is accelerating that in starting vehicle can be effectively improved
Performance reduces motor volume, weight, but AMT speed changers need complete set gearshift controller and perfect operation to control
Strategy, in practice, due to needing to carry out speed regulating control shift in AMT shift processes, to precision of fuzzy controller and rotating speed
With more demanding, cause ring gear that can not mount into tooth set to cause to shift gears there are power interruption, adjustment of rotational speed control are inaccurate
Failure equivalent risk so that technology effect in practice is poor, and because AMT mechanical structures itself generate failure and other reasons,
Overall failure rate is higher.
4, the technology that DAT two speed transmissions combine can reach wanting for shift seamless connection by friction shift control mode
It asks, shift quality and stable ride comfort obtain larger raising, in demonstrating on board and engine bench test, product stability and electricity
Consumption etc. is superior to AMT configuration schemes, but there are vulnerable parts to be arranged between speed changer and motor for the assembly, and Maintenance and Repair are tired
Difficult problem；Simultaneously such as transmission fluid leakage, easily the brake-shoe of shift and clutch disc are polluted so that shift process
Friction plate or brake hub skid and failure of shifting gears.
In conclusion all there is different problems, motor in the driving device of existing new energy pure electric vehicle application
Fail to reach reliable and stable requirement in properties of product, maintaining, reliability etc. with after transmission combination.
