  • 6RA40特性

    ·同轴行星轮系变速器

    ·液力变矩器带打滑控制的锁止离合器

    ·配有内置TCU的液压控制单元

    ·自我诊断功能

    ·换挡响应时间短

    ·整体设计有效提高燃油经济性

  • 6RA40 FEATURES

    ·6-automatic forward gears

    ·1 selectable reverse gear

    ·Coaxial planetary transmission

    ·Hydrodynamic converter with controlled converter lock-up clutch(GWK)

    ·Hydraulic control unit with integral electronic transmission control(EGS/TCU)

    ·Electronic-hydraulic shift point position and gear shift control

    ·Mechanical gearshift option with 7 optional selector lever positons

    ·Short response time shifting

    ·Self-dianosis

    ·Fuel economy

  • 控制器主要控制功能

    ·自动变速

    ·T变速器自我保护:低档互锁、超速档互锁、倒档互锁

    ·错误换挡(例如:发动机转速4000rpm,从N-D,N-R)市,ECU可根据变速器的请求降低扭矩

    ·缺省/紧急模式
    当ECU失效时(断电),下列档位将被使用
    1-3档失效时,接合第三档
    4-6档失效时,接合第五档;
    重新启动时接合第三档

    ·Can通讯功能

  • MAJOR TRANSMISSION CONTROL

    ·Transmission Function

    ·Transmission self-protection function:Downshift interlock,over speed interlock and reverse Gear interlock

    ·Misuse shifts(e.g.changing form N-D,N-R,at engine speed 4000 rpm) are conteracted by the engine controller which reduces the engine torque on transmission

    ·Default/emergency mode
    If the ECU fails(no power), the following forward gears will be engaged.
    Failure in 1st-3re gear Emergency gear:3rd
    Failure 4th-6th gear Emergency gear:5th
    3rd gear is engaged following a restart.
