混合动力总成系统具有混合动力变速器、内燃机、电动发电机和带有至少一个可驱动的驱动轮的传动系统,混合动力变速器设置用于接收内燃机的驱动功率、即内燃机驱动功率和接收电动发电机的驱动功率、即电动驱动功率以及将至少一种或两种驱动功率输出给传动系统,且混合动力变速器还具有至少三个挡位,这三个挡位由至少两种不同类型的挡位构成,混合动力变速器具有可切换的变速器、即换挡变速器,其设置用于提供所述三个挡位中由第一类型挡位构成的至少一个挡位、即固定传动比挡位,由第一类型挡位构成的这种挡位分别具有针对内燃机和电动发电机相对于传动系统接头的由换挡变速器的结构类型确定的传动比,且混合动力变速器还具有转速叠加变速器,其设置用于提供所述三个挡位中由第二类型挡位构成的至少一个挡位、即动力分流挡位,这样的动力分流挡位是关于内燃机接头和传动系统接头具有可变转速传动比和固定扭矩传动比的挡位,且可变转速传动比在混合动力变速器中借助由内燃机提供的转速和由电动发电机提供的转速的转速叠加构成,混合动力变速器具有至少一个运行模式,在该运行模式中仅在不同类型的挡位之间实施换挡。
A hybrid gearbox has a shift gearbox including at least one fixed ratio gear having a gear ratio both for the internal combustion engine and the electric motor-generator with respect to a power train connection, and speed superposition gearbox which is designed to provide a power-split gear having a variable speed ratio and a fixed torque ratio with respect to the internal combustion engine connection and the power train connection, wherein the variable speed ratio is formed by a modulation of a speed provided by the internal combustion engine on a speed provided by the electric motor-generator. The hybrid gearbox has at least one operating mode in which gear changes are only carried out between the fixed-ratio gear and the power-split gear.
