What do the 4HLC and 4LLC on the handle of Mitsubishi V73 four-wheel drive mean?

Judging from Pajero's four-wheel drive structure, the central differential is purely mechanical+hydraulic coupling, and the V97 also has a rear axle differential lock, while the V93 does not. So: \ x0d \ x0d \ 2h, I won't talk about it, rear wheel drive. \ x0d \ x0d \ 4h mode (high-speed four-wheel drive, differential lock unlocked), which should be a hydraulic coupling when working, and transmit power through the viscosity of expanding liquid, \x0d\ 1. If the differential lock on the rear axle is not opened, then the differential on the front and rear axles should be opened, which should be harmless to the car and free to accelerate the corner. This is the working state of its design. Provide better grip. On the slippery road surface that is not particularly serious, the fine gravel road surface. Provide better handling. \x0d\2。 If the rear axle differential lock is opened (it is best not to use it on high-speed or expressway), the rear wheels will be worn, especially the tires on the outside of the curve when turning, and driving at high speed will seriously affect driving safety. This will also unnecessarily increase the burden of the rear axle differential lock. \x0d\ Long-term 4H mode may keep viscous coupler in high temperature and high pressure state for a long time, which will test its reliability. However, this is also its normal work. If something goes wrong, it only means that there is something wrong with the quality of the viscous coupler. \ x0d \ x0d \ 4hlc (high-speed 4-wheel drive with differential lock) mode, the central differential is mechanically locked, and the hydraulic coupler no longer works. \x0d\ 1。 If the rear axle differential lock is not opened, the differential between the front and rear axles should be opened, which should not cause any harm to the car. This is also the working state of its design, and it can bend at high speed. The front and rear axles get the same power. On the wet pavement, the fine gravel pavement provides more stable four-wheel traction than 4 hours. \x0d\2。 For example, for 4H, if the differential lock of the rear axle is opened, the rear wheel will be worn, which is normal in off-road conditions, but it will seriously affect the driving safety when driving at high speed. Therefore, when driving on the highway, do not open the differential lock of the rear axle. At this time, it is best to turn off the M-ASTC, because it conflicts with the differential lock on the rear axle. In extreme cases, M-ASTC will apply braking and increase power to different wheels at the same time, but the differential lock will lock them. It will do harm to both sides. \x0d\ Mechanical differential lock is very reliable and generally won't be damaged. \x0d\\x0d\4LLc (low-speed 4-wheel drive with differential locking) mode, the central differential is locked mechanically, so it is impossible to cut into this mode during movement, and it is necessary to stop. At this time, M-ASTC is automatically closed. \x0d\ 1。 If the rear axle differential lock is not opened, the differential between the front and rear axles should be opened, which should not cause any harm to the car. This is also its designed working state, and it can only travel at a speed of less than 30 kilometers. Provide maximum traction. The front and rear axles get the same power, providing more powerful four-wheel traction on muddy and bunker roads. \x0d\2。 If the differential lock of the rear axle is opened, the rear wheel will wear. Of course, no one will care about the wear and tear caused by tire skidding under low-speed off-road conditions. At this time, the slipping tire will have little wear because it has no adhesion. This is also its normal working state. When the differential lock of the rear axle is opened, both rear wheels will rotate at the same speed regardless of whether they slip or not. So as long as one rear tire has adhesion, it can get out of trouble. \x0d\ But at this time, if both rear wheels are stuck in the mud and only one front wheel has grip, the bobcat is likely to sweat. . . M-ASTC is closed, and the front wheels can't brake the skidding tires. Only ABS can provide intermittent braking, which may have little effect. The front axle power is transmitted to the skidding front wheels. Can be changed to 4HLc+ rear axle differential lock, M-ASTC on, manual 1 gear. Let's try to get out of trouble. 3 Ling closed the M-ASTC probably to protect the M-ASTC and the rear axle differential lock. But I don't know if I can use 4LLc in extreme cases, and manually open M-ASTC, and close M-ASTC immediately after getting out of trouble? Comrades who know it can discuss it together. \x0d\\x0d\ Regarding the V93, since there is no rear axle differential lock, when 4LLc is opened, M-ASTC will automatically close. At this time, its off-road ability may not be as strong as when 4HLc is turned on. Low-speed four-wheel drive does not have ASTC to brake the skidding wheels, and can only get out of trouble by low speed, large traction and large inertia. It can be seen that the positioning of V93 is slightly different from that of V97, and the positioning of V93 is more inclined to urban and general field road conditions. Thanks to the configuration of the differential lock on the rear axle, the V97 can be full of confidence in bad field road conditions. \x0d\\x0d\ Regarding the rear axle differential lock of V97, even in off-road state, if there is no traffic jam, it is best not to open it, which will wear the tires. Therefore, the positioning of the V97 once again shows that it needs a professional car owner. Not everyone can drive well. No matter how you drive the V93, it generally won't damage the vehicle. Car owners can drive well and play well without professional knowledge. \x0d\\x0d\ So Bobcat's: central differential lock, rear axle differential lock, ASTC, their collocation is used by all owners of Bobcat, so it should have a good experience after owning it. In this way, we didn't mistreat this big toy. Compare some off-road vehicles in Europe and America, such as Touareg, Cayenne and Land Rover. The independent configuration of Bobcats fixes several mode combinations, which is silly and much more fun and flexible. Because it can be combined freely, it can cope with more road conditions. Generally, this free combination only appears in very professional vehicles, such as Shepherd and Mercedes-Benz G-Class.
