宝马X6 E72混合动力车型实际上是在传统宝马X6车型的基础上增加了电动机、高压蓄电池和供电控制装置,从而实现了混合动力,起到节能和提高驾驶性能的作用。宝马X6 E72混合动力车型采用的是宝马Active Hybrid混合动力技术,它是通过主动变速器(图1)将发动机与电动机的动力输出进行混合的,主动变速器不再是单纯的传动系统,而是车辆的动力源之一。宝马X6 E72混合动力车型的主动变速器与传统自动变速器一样,自动变速器输入端和输出端之间传动比不同。从驾驶人的角度来说共有7个前进挡位。在自动变速器内部,这7个前进挡位通过4个固定的基本挡位和具有可变传动比的两个模式实现。在4个固定的基本挡位中,发动机和 BMW X6 E72 hybrid is actually based on the traditional BMW X6 models added a motor, high voltage battery and power supply control devices, enabling hybrid, energy saving and improve driving performance. The BMW X6 E72 hybrid uses the BMW Active Hybrid hybrid technology, which mixes the power output of the engine with the motor through an active transmission (Figure 1) that is no longer a purely powertrain but a One of the power sources. Active Transmission in BMW X6 E72 Hybrid Like conventional automatic transmissions, the transmission ratio is different between the input and output of the automatic transmission. From the driver’s point of view a total of seven forward gear. Inside the automatic transmission, these seven forward gears are realized by four fixed basic gears and two modes with a variable gear ratio. In four fixed basic gear, the engine and
