The invention discloses a transverse torque vector transmission of a three-motor hybrid electric vehicle. The transverse torque vector transmission comprises a first driving motor, a second driving motor, an engine, a generator, a left middle shaft system, a right middle shaft system and a planet row transmission system. On the basis of a dual-motor hybrid power speed reducer, torque vector distribution and engine power coupling are achieved through a planet row transmission system and a driving motor, torque can be accurately transmitted to each driving wheel, the harsh requirement of people for vehicle controllability is effectively met, and through application of a plurality of working modes, the reliability of the hybrid power speed reducer is improved. By means of the method, the vehicle can adapt to various working conditions, it is guaranteed that the vehicle has good fuel economy, the torque vector distribution function is achieved, the steering effect of the vehicle is improved, the dynamic performance of the vehicle is stabilized, the vehicle is helped to bend, the operation intensity of a driver is reduced, the insufficient steering phenomenon of the vehicle can be reduced, and the dynamic performance of the vehicle is improved.

    本发明公开了一种三电机混合动力汽车横置扭矩矢量变速器,包括一号驱动电机、二号驱动电机、发动机、发电机、左侧中间轴系、右侧中间轴系、行星排传动系;在双电机混合动力减速器的基础上,通过一个行星排传动系,增加一个驱动电机,实现扭矩矢量分配并耦合发动机动力,可以将扭矩精确地传输到每个驱动轮上,有效地实现人们对车辆操控性的苛刻需求,通过多个工作模式的应用,本发明能使车辆适应多种工况,保证车辆具有很好的燃油经济性,并且具有扭矩矢量分配功能,增加车辆的转向效果,稳定车辆的动态表现,帮助车辆入弯,减小驾驶者的操作强度,并可降低车辆的转向不足现象,提升车辆的动态性能。
