Automotive structural very complex, but principle a word can say clear: an internal combustion engine and a tire connected can start to run after.
One only? Can only and a tire the connection?
Of course. Only this time the car in direction may not too good grasp it.
A? Car is not four wheels?
If we can keep balance of words, one, two, three, all can. Six eight also no problem, if you like, make him a hundred dozens of only the car to create record wheel.
Output can be directly connected to engine tires?
Of course. This time the car could not so good driving, and possibly starting some lack of smooth - run fixed was hardly surprising. Because the internal combustion engine low rotation speed when cannot output enough torque. Motor does not exist this problem, so it can be done directly on the wheels, this is the so-called "wheel edges motor".
This is the power. Very simple?
The engine and tire how to connect? In fact, how even can, say, or one of the wheels connected only to connect two, diagonal style may also come a whimsical, give the car a few more to pack his only wheels, like this.
Well, usually symmetric words may be more easy to control the car. So, car drive mode later turned into a such three:
After all the flooding, precursor, displacement.
There are some other spy car, is like this:
These belongs to the special purposes, such as military vehicles or skidoos, usually special car definition can ignore their presence.
Of course, the engine installed in what position, it also has all kinds of different solutions, most of the car's engine outfit in the head, called "lead", from this name, I think you can easily to suss out "buy" and "rear" what is going on. These and vehicle design, dynamic performance and balance is closely linked. And it is very common. For example, the early bus often adopts front engine is designed, it is right that bulges lymph driver below content. New bus had mostly used in the rear and buy design.
Farther down will be involved in dealing with the relative position of the axle shaft etc, it's deep, slowly.
Back to drive form.
Precursor (FF), is the power of the engine front wheel, shuttled directly by "pull" rear wheel just ran. The benefit is designed so that it can be the crew cabin floor design gets lower and flat, no necessary prerequisite hind drive shaft made "the piece." bulge Of course some former drove didn't remain this manner, like stupid soar team, incredibly let vent-pipe formed "beat", back center can also take?
Precursor characteristic is to understeer. Don't worry, in fact, understeer is usually stability good pronoun, so difficult in high speed cornering happen, even if high speed to recovery, as long as less confidence suddenly just keep the power. But the shortcoming also come, because the reason, when layout, because the barycenter uphill backward-shift, front wheel adhesion drops, more likely to happen to skid. So you snow slope gets up time, must light oil. Snow level road started hanging second try (actually it is some cars bring when selling "snow mode").
Precursor won't lateral spreads? Not. Its lateral spreads, if it happens, more dangerous than hind drive. Because of its whole layout makes gravity in front, when high-speed braking, rear axle lotus ahead to lock and cause lateral spreads, this makes the operation is not easy to control, you may find just still understeer car suddenly became oversteer. Nevertheless, also need not worry too much about, ESP popularization after, this problem is no longer exist.
When turning more to a little oil, then gently shake handshandle brake can cause the sliding. This is the most simple lateral spreads - in fact most open civil car have claimed their mastery of the "floating" is this movement. I can reliably tell you, this is not the necessary conditions of drift, drift is against dozen direction. The more difficult and dangerous, turn head again.
After this very simple, displacement, rear wheel drive! The engine on the front is in three different after the combination. Cheaper cars, engine installed in front, expensive porsche or ferrari new push in the California became more expensive or the like F1 and most top sports car, acquired after all. Of course the rear will not necessarily expensive, lead of also uncertain cheaper, exceptions.
Here say first lead hind drive (FR), this is ordinary people could afford the most common civil car. It compared with pioneers, the biggest advantage is that horsepower can do much, because as the front wheel and drove before driving wheel and steering wheel so that it cannot afford big power, at present is the usual practice in less than SanBaiPi. Then flooding have born between front axle SanBaiPi Idaho evenly distributed, after flooding for sports car just started just, five hundred female? Or LiuBaiPi? No problem. Some crazy American muscle cars will have been increased to a thousand horsepower, don't know how they open. Anyway I don't control, a car will start spinning it.
The driving feeling after flooding far above precursor, only drivers and front-seat crew member's counterweight especially ideal, when will show neuter turn or slight understeer, this kind of driving feeling is very good, open before the people used to drive will immediately feel lighter, direction flexible headlights. But lateral spreads are also more likely to appear, as long as you turn of bigfoot throttle, when the basic can immediately experience the feeling of rear lose adhesion. So, for most is concerned, the driver abraao after flooding is not a choice.
If you want to pursue some fun, after flooding is best choice. For example, there is a left turn in front of normal turn-in is firmly before the heart in bend down and then left the accelerator play direction, etc when on the exit route headlights acceleration3. This is the standard of best practices. But if your car capacity is sufficient, can be so open: in the "right" place first toward right-handers wheel, rapid headlights slightly towards the left when we play wheel, quickly at the rear of the car will produce the trend to the right, then the accelerator, the play deep (at right), the direction you eyes will appear short singular sight, the world in happen lateral movement! The outside person looks, you this time there will be in a state of unthinkable, wheel clearly to the right, but the car was driven to the left.
This is a right turn the drift action, attention to its front wheel is to the left.
This theme related photos as follows:
This is difficult, the general car drift action before hanging not so hard, differential locking rear axle and not so share, so, you'd better not try, will have an accident. Differential locking is what? Well, very simple, is a can produce relative sliding thing, can take care of it.
Actually to control car with more vividly described more essence is controlling the car, but that my personal gravity limited, belong to truly understand, will not be absurd navel-gazing level. In this respect the world a newbest man is Hamilton, he can quickly adapt to the car and find its limit, in the control almost nobody can bend and, this belongs to the talent, I'm afraid I never made out.
Raider. This is the more simple. The power of the engine are passed on to the four wheels, after flooding can now than precursor for greater motivation, then raider can bear larger than the power after flooding -- anyway don't tube much besides four also didn't have much, still can make better use of four tire grip, thus obtained an absolute advantage in started to snow, such as wet ground of nature is handy. So the place like the in northern Europe, buggies accounted for sales advantage proportion. And ran mud car is exclusively buggies.
In steering characteristics, raider will have a tendency to understeer.
Of course, raider and points, the high-speed low-speed timeshare full-time by not list.
Finally, simply to summarize. Assuming a depot will the same chassis the same engine car produced three, respectively is precursor, hind drive, raider, engine can provide SiBaiPi horsepower, so:
The weight of the transmission system is the most light, which in turn increases precursor.
Who accelerated faster?
And accelerating performance is the most slow, which in turn increases precursor. But ran straight line acceleration first rushed to key in accordance with the order, not because the highest speed is not necessarily the raider, perhaps faster, drive after flooding because of losses small.
Ran track?
Most is the slowest precursor, flooding and raider is difficult points in the same caliber, need the driver's preference and road conditions and calm, no certain answers. In most cases I'll vote for the tickets, after flooding because raider can let you steadily on the circuit out of the best lines, the lateral spreads after flooding may make you lose time, but also have the opportunity to let you on a faster bending direction. And, for sharp curve, properly use before more than bent slowing recovery can keep high speed and uninterruptable power output, this in detail and variable is too much, no certain answers.
How do I distinguish buy car is precursor or after flooding?
When we looked around, the whole market you can see cars most were the pioneers. Without him, manufacturing and the cost of maintenance is depot primary consideration. And the crew to flat floor is more practical.
Of course, if be sure, usually propaganda page will be identified. FF, or "lead precursor".
Adhere to the manufacturer, after flooding the few German BMW and M, Japan factory RuiZhi crown, TOYOTA, NISSAN's infinite is probably can see on market at present in the rear.
If you care to size, the bus is mostly the displacement, open a after twenty or thirty people can sit car, the traffic jam car to go to work when still can stand up exercise, is great! When is the parking there could be trouble, some parking lot may refuse you enter, and some parking lot you simply can not open in.
After flooding and raider which good?
Small cars, a high proportion of the raider can make full use of grip. But in order to provide a fun, usually turn with will power distribution tuned tend to rear wheel, create some oversteer characteristics, like the EVO or the SUBARU mitsubishi Impreza. But these cars in the size is compact, with audi A6 price is the price of intermediate configuration, so much for not similar to the person, the road performance obviously it is not what good choice.
But from another point, if you intend to briefly forget the speed limit, in some safe sections try roadside scene becomes fuzzy is what feeling, this small car becomes quite have the cost-effective option. And those than it costs double compared the car also opened. This is why the racing from London or Salt Lake City group of a can find them figure's sake.
The Audi TT is technical flow performance eugenic. Electromagnetic suspension, active steering, and relatively rough original Japanese cars, except I didn't open than ever, nothing too big failing. See is seen, but other people's car, the heart to itch also have to take it easy. Besides if only to open, TT by spectrum with the jetta I see also nothing more low, perspective respectively, maintenance TuoDe are also more likely to die, fill your price of a paint you can buy computer. So this story tell us, money is a good thing. If money still is complaining about not happiness, "the goddamn pack to force committed.
