现今,汽车厂商在高扭矩输出车型上越来越多地采用了四驱技术,除了对车辆主动安全性大幅度提升以外,在极端路面上的操控能力也提升不少。近几年,各大汽车厂商开发的全新四驱系统效率更高、体积更小且重量更轻,前后轴扭矩分配更为宽泛,结构也更为简单。甚至有些厂商已经将四驱系统的核心组件中央差速器集成到了变速器中,譬如斯巴鲁和奥迪。即便有了如此多的进步,但上述机械式四驱系统依然存在不少“硬伤”。在我看来即便投入—块钱在机械式四驱系统上都是多此一举。
Today, automobile manufacturers are increasingly using four-wheel drive technology in high-torque output models. In addition to a substantial increase in the active safety of vehicles, the handling capability on extreme road surfaces has also increased a lot. In recent years, the new four-wheel drive system developed by major automobile manufacturers is more efficient, smaller and lighter, with a wider distribution of torque on the front and rear axles, and a simpler structure. Even some manufacturers have integrated the central differential of the four-wheel drive system into the transmission, such as Subaru and Audi. Even with so many advances, but the mechanical four-wheel drive system there are still many “flawed.” In my opinion, even if invested - bucks in the mechanical four-wheel drive system are superfluous.
