n characteristics, different from other battery, the battery, need not only external constantly supply of fuel and electricity can continuously steadily. Fuel cell vehicles (FCEV) can be matched with the car engine performance and fuel economy and emission in the aspects of superior internalbustion vehicles. Keyword: drive axle differential bridge reducer Bridge shell This is an ANSYS optimum design for driving axle housing of a offroad vehicle. Firstly, the author established a threedimensional model of the driving axle. States of stress in different working conditions were analyzed. Furthermore, the maximum pressure of driving axle was achieved. And then, the threedimensional model was imported into ANSYS, with some other manipulations, such as meshing, adding degree of freedom, applying surface loads, etc. States of stress of driving axle were calculated with the results exported. Finally, this paper carried out the optimum design according to the target of minimizing the qualitative properties and homogenizing the distribution of stresses. The Confirmatory analysis showed that this design measured up to the engineering requirement. This invention relates generally to a powertrain for a vehicle, and, more particularly, to a powertrain having multiple power sources including an electric motor for driving a set of vehicle electric powertrains have been developed that include an electric motor and an internal bustion (IC) engine, which can operate independently or in bination depending on the driving conditions, the state of charge of a traction battery, and the power source that most efficiently meets the current power demands imposed by the vehicle electric hybrid vehicles available mercially are front wheel drive vehicles, in which only the front wheels are driven. Hybrid electric powertrains being developed for use in fourwheel drive vehicles allow both the motor and engine to transmit power to a rear set of driven packaging an electric motor drive unit for a rear axle it is preferable to use a lay shaft power flow such that the motor drive unit is placed on the rear axle centerline. Such electric hybrid drive systems, however, present packaging difficulties to the vehicle designer, particularly when layshaft gearing is used to transmit power from a longitudinal drive shaft to a rear need exists for a hybrid electric powertrain in which one axle is driven by an electric motor or an IC engine in bination with the motor. To minimize cost, an electric machine would provide all hybrid functions including electric energy generation, electric vehicle launch, engine starting, electric boosting of engine power, and regenerative braking. A drive unit for a hybrid electric motor vehicle includes an engine, an electric machine including a rotor, a layshaft gearset including an input driveably connected to the engine and an output, for transmitting power between the input and the output and producing a first speed differential that causes a speed of the input to e
