4WD four-wheel drive form, if according to the different structure can be divided into time-sharing four-wheel drive, full-time four-wheel drive, timely four-wheel drive and other common forms. There is also a maverick four-wheel drive form, because the functions are too complete and powerful, it is difficult to divide according to the previous standards, it is Mitsubishi's exclusive technology: super selection four-wheel drive.
Time-sharing four-wheel drive is known for its ruggedness, and full-time four-wheel drive is also favored by many people for its high adaptability and convenient operation. The super-selected four-wheel drive can be described as the culmination of two.
So what is the advantage of super selection four wheel drive? The essence of super select four-wheel drive is a set of full-time four-wheel drive, but it can be switched to a 2WD two-wheel drive form similar to time-sharing four-wheel drive to increase economy; secondly, it can switch 2WD and 4WD at any time below 100km/h, and even open or close the central differential lock directly without stopping at the same 100km/h; its 4H gear when the central differential can adjust the front and rear torque distribution at any time, more active, This extends the ASTC active stabilization and traction control system.
Mitsubishi Pajero Jinchang is an all-terrain vehicle that performs well on road, Gobi, desert and polar xian off-road conditions. From the initial design goal, Pajero Jinchang was tasked with multiple road conditions, and the road conditions targeted by the Super Select 4WD (Super Select 4WD system, abbreviated SS4) were also equipped.
The first generation of ultra-selected four-wheel drive system adopts mechanical structure, highlighting reliability, and the gears are divided into 2H, 4H, 4HLc and 4LLc, that is, two-wheel drive, four-wheel drive, four-wheel drive lock-up and low-speed four-wheel drive lock-up mode. Among them, the three modes of 2H, 4H and 4HLc can be switched when the speed is less than 100km/h, and the road can use 4H, the front and rear torque is distributed according to 50:50, and the torque distribution is adjusted by the VCU when skidding.
In 1999, the third generation of Pajero was launched and equipped with a modified super-selected four-wheel drive system, which is what we call the second generation. Compared with the first generation, the operation changed from mechanical to electronic, and the torque distribution of the front and rear wheels in 4H mode became 33:67. At the same time, the VCU in the second generation of super-selected four-wheel drive has also become an electronically controlled adhesive coupling, which is more active and fast, and in 2004, a new equipment was added to PAJERO - M-ASTC, that is, Mitsubishi active stability traction control system. The second-generation Super Select Four-Wheel Drive system has been used to this day, and is equipped with the fourth generation of Pajero and Pajero Jinchang.
The excellence of the super-selected 4WD is the integration of full-time 4WD and time-sharing 4WD, which takes into account economy, handling and off-road performance. The key to this is the addition of 2WD & 4WD selection mechanism, and the second is the addition of VCU adhesive couplings in parallel to the central differential, and these two points are the same in the first and second generation of super-select four-wheel drive, and are also the technical highlights of super-select four-wheel drive.
