I've been writing about lion's manipulations all this time, although they're not strictly “car diaryes”, but they're really the feelings that i've accumulated over a long period of time and through a variety of circumstances, and it's still interesting for you to get to know more about the lion. It is time to talk about one of its core techniques — full-time four-way。
The neutral shift of the limits to the properties
Full-time round drive (full-time all wheel drive) is a symmetry technique across the sbaru family, but the manner in which each sbaru model actually achieves full-time four. On the power lion system, the top 2. 5 gt, 2. 0 and 2. 5 cvt models, the manual block type, have three different full-time four-way drivers, the difference being the form of the central differential and the ratio of the pre- and post-power distribution, of which 2. 5 gt and 2. 0i are based on 50:50 power distribution, while 2. 0 and 2. 5i matching cvt are based on 60:40 power distribution。
The full symmetric four-way system in sbaru has a more even ratio of pre- and post-drive power distribution than those developed on a previous or back-drive basis, which can be understood as a “pure four-drive” rather than a one-sided or back-drive. So, in the extreme dynamics of the bend, sbaru can achieve a truly typical “neutral shift” — increasing the oil door in the bend, and you feel that the rotational force is equal, neither pushes, throws, nor throws. It gives you the comfort and confidence to press the door when you bend, and the more you give it to the car, the more proactive it is in the direction of the wheel. Of course, it has limits, and if the gas door is too big, the tires will break the limit and slide, but the slides of the back and forth wheel are basically at the same time, so even if it's going to slide out, it's going to slide out, instead of stomping out of one head or pulling out the ass -- - that's exactly what it feels like when the lions go over the edge of our field。
What's full-time four-way
Some people drive into sbaru's car and turn around and say, "stand! Indeed, in a state of transition that is generally far from the limits, the sense of stability is entirely attributable to the chassis. The advantage of a full-time four-way drive can only be demonstrated at the limit, which has two effects。
The first is to increase the strength of tyres. Since the full-time 4-wheel drive divides power to four wheels rather than to two wheels, the full-time 4-wheel drive is less likely to slide because of the speed that leads to the driving wheel breaking ground, and is less likely to lose control of the tires (often driving wheeles) breaking ground in an environment of over-extension and low intensity (rain, snow, sand)。
The second function is “hidden” and may not be well understood. Since the pre- and post-four-hour power distribution ratio is fixed in a relatively small range (e. G., 50/50 or 60/40 in sbaru, even a reversible sti is no more than 35/65), if not in a dynamic state, the four wheels are “linked” to the engine through a full-time four-way traditional system. When vehicles want to lose control, this “linking” can have a disproportionate effect in limiting the speed of wheeling before and after, limiting the full freedom of rolling of the wheel before and after, so that the car is by nature moving towards a stable state of straightness, which makes it more difficult for the vehicle to have a large swing and turn back。
For that reason, sbaru had introduced esp-type electronic stabilization systems more passively on the early generation of old-age lions and panthers, because full-time and early-life esps were similar to esps to prevent vehicles from turning their tails, except that it could not help drivers slow down like esps, or security was less effective than esps, and sbaru had to adapt to the tide to develop its own electronic stabilization system, vdc. We've tested the force lions for emergency diversion and found that even when the vdc was shut down, the attitude of the vehicle was more constricted when it went out of control, and that it was not easy to “show”, which was the effect of full-time push-over。
Compared with other four-pronged advantages and disadvantages
Finally, the full-time four-way approach is different from the other four. A full-time four-way drive must be dynamic at all times in the back and back of the wheel and can function instantaneously in a state of sudden extremes. In many cities, suvs use “smart four-way” or “timely four-way”, which is two-way at a time when a maximum condition (drive slide) is detected before a four-way is activated. This “slutch” four-drive approach to road manipulation and active safety does not help, but only increases the pull at low speeds and prevents vehicles from slipping onto bad roads. So we talk about increasing manipulation on good roads, which must be full-time four-way, because only full-time four-way reaction is fast enough (which, strictly speaking, is not required)。
What's wrong with full time? The most direct is fuel consumption. As a result of the constant effort to provide four wheels, power losses are greater and have a negative impact on speed and economy. This is also the reason why most of the other manufacturers are developing smart four-way systems that, in due course, “slugger”. For a producer like sbaru, who insists on full-time four-way drive, full-time four-way, users must try to minimize its shortcomings while promoting full-time four-way advantage. This has forced sbaru to invest more in energy efficiency performance in engines and gearboxes to compensate for the negative effects of full-time round-trip. The actual fuel consumption of our strong lion 2. 5i has reached a level of excellence comparable to that of the yalk 2. 4, accelerability and a level of 2. 4 and 2. 5 litres of natural inhalation, and it is clear that sbaru has done quite well on the engine and on the cvt gearbox so that they can preserve the full-time four-way tradition of their faith, which i dare say they have succeeded。
