Zusammenfassung:The invention provides a four-wheel drive force distribution apparatus which is used for improving acceleration performance and turning performance of a vehicle. A four-wheel drive force distribution apparatus for distributing drive forces to the wheels of a four-wheel drive vehicle, in which the distribution of drive force to the front inside wheel (2a) and the distribution of drive force to the rear inside wheel (3a) are adjusted based on a ground load of the front inside wheel (2a) and a ground load of the rear inside wheel (3a) when the vehicle is turning, and the distribution of drive force to the front inside wheel (2a) compared with distribution of drive force to the rear inside wheel (3a) is reduced the smaller the ratio of the ground load of the front inside wheel (2a) to the ground load of the rear inside wheel (3a) during turning. 本发明提供四轮驱动力分配装置,用于使车辆的加速性能以及转弯性能提高。在向四轮驱动车辆的各车轮分配驱动力的四轮驱动力分配装置中,当车辆转弯时,基于前内轮(2a)的接地载荷与后内轮(3a)的接地载荷来调整向前内轮(2a)的驱动力分配量与向后内轮(3a)的驱动力分配量。转弯中的前内轮(2a)的接地载荷相对于后内轮(3a)的接地载荷的比例越小,则
