Super four-wheel drive can not only drive alone in the rear drive state, but also drive in the four-wheel drive state. The key is to switch between two-wheel drive and four-wheel drive, which can be switched directly at high speed without stopping running. In addition, the super-selected four-wheel drive has&; Ldquo axle differential &; Of course, in the four-wheel drive state, the principle is more similar to the full-time four-wheel drive, and you can turn on any highway.
I think for many fans, the super-selected four-wheel drive system is no stranger. It was invented when the second generation Pajero (1992) was born. Do I think the superselective four-wheel drive system is backward? I think the super-selected four-wheel drive has been continuously polished and modified, and has been used to this day, becoming the most advanced and best four-wheel drive system.
Usually, the 2H mode can be selected to save fuel on paved roads, but the two-wheel drive mode cannot be realized for well-known vehicles equipped with TOSON central differential, such as overbearing and land patrol.
On wet and rainy ground, roads and mountain roads, you can choose 4 hours, which is full-time four-wheel drive. With the central differential, full-time four-wheel drive is naturally realized. The power distribution of front and rear axles is 50:50 (first generation) and 33:67 (second generation), which can improve the maneuverability of complex road conditions and the driving stability of vehicles.
On unpaved ground (sand, muddy roads, etc. ), you can choose to use 4HLC, which is equivalent to the high-speed four-wheel drive of a hard-core part-time four-wheel drive off-road vehicle. At this time, the central differential of the vehicle is locked, the power distribution of the front and rear axles is maintained at 50:50, and the front and rear outputs are constant.
Finally, 4lc is used to get out of trouble or climb a big slope, which is equivalent to a low-speed four-wheel drive of a hardcore part-time 4wdSUV. At this time, the central differential of the vehicle is locked, and the power of the front and rear axles is also 50% of each output. At the same time, the transfer box is switched to low gear, and the torque is amplified to 1.9 times.
