Drift is defined
drift (drift, drifting) racing term, refers to a point so that the front of the vehicle body and have a greater angle between the actual direction of motion, the vehicle body slip cornering series of operations.
The conditions of drift
drift of blame in the end is a: the rear wheels lose most (or all) grip, while the front wheels to maintain grip (can only lose small portion, preferably the additional grip); then as long as there is a certain wheel lateral force, the car drift, can drift. The method
There drift
1. The straight road running direction of play after pulling the handbrake
2. The pull handbrake cornering
3. The straight road after running braked hard hit direction
4. braked hard cornering
5. when sufficient power to drive (or rear wheel drive force distribution ratio tends to drive the rear four-wheel drive) pedal to the metal when the speed is not high and the direction of play .
where 3,4 is the use of weight transfer (transfer weight to the rear wheel), a method of least hurt the car. 1,2 only for front-drive and four-wheel drive rally racing, but also it can avoid paying for, unless you’re afraid of broken car. Note 1 and 2, 3 and 4 separately, because the movement route of the car will be very different. Important: general drift cornering and cornering, as there are speed limit, and drift cornering speed limit of a maximum possible cornering a little higher than normal, hard ground drift cornering speed limit is lower than the average cornering!
As can eventually drift, with a coefficient of friction between the tire and the road surface, vehicle speed, braking force, the size of the throttle, the size of the front wheel angle, vehicle weight distribution, wheel base tread, suspension hardness and the like related to a number of factors. Such as rain, snow drift driving want is easy, but does not want to drift more difficult; the higher the driving speed, the easier flick (it is the first safe driving is not to drive fast oh); the direction of play quickly, too easily drift (called master taught me driving too fast, oh I do not hit the steering wheel); the smaller the track wheelbase, the higher the body, the more powerful weight transfer, the more easily flick (also easy to roll!); front suspension anti-roll the role of the weaker, more easily flick.
The flickControl
If it is to drift with the handbrake, then when the car rotate to your desired angle, it should release the handbrake.
drift in the middle of the task is to adjust the body posture. Because the road surface unevenness, the degree of bending line, cornering characteristics of the car and other factors will often change. So drivers often have to control the steering wheel, accelerator, brake, clutch and even (not recommended) to make cars with the driver in accordance with the desired route.
to point out the principle: let the wheel slip long distance, it should minimize the friction between the wheels and the ground; make small slide wheels, it should increase the frictional force. The method of reducing friction of said front, so that a wheel is rotated too slowly or too quickly, a wheel is reduced between the positive pressure surface; a method of increasing the frictional force is opposite.
wherein the slow rotation of the wheel so that the method that is the step on the foot brake or the hand brake (Again: the foot brake is applied to the four wheels, the handbrake is applied to the rear wheels regardless of whether the handbrake. other acts on the wheel of the car, I know there are racing all my handbrake said the situation)
step on the foot brake: four wheels will slow down and eventually lose more after the front wheel or friction wheel lose more friction can not be generalized.
handbrake: frictional force is not lost while the rear wheel loses large friction, it can easily cause the oversteer. Because both the foot brake, handbrake has deceleration effect, so the car will soon stop skidding.
The real drift
And if you want a long distance wheel slip, the only way is to make high-speed idling wheel must be fitted with LSD, the only car with sufficient power to do so . LSD Why should it? Because the body will tilt the car drifts, the wheel pressure on the ground outside of the large and small the pressure inside the wheel. LSD does not occur inside of the vehicle drive wheel idling, the outer rotation driver slowly case. The wheels turn slowly and ground friction between the large, sliding the car will stop soon.
into the precursor vehicle, rear wheel drive, four-wheel drive, the driving force of the wheels is not possible high-speed idling. Then the first long-distance drive the rear wheels do not skid, if the drive wheels (i.e., front wheel) high idle, than the rear wheel side slip, angle of driftDegree decreases, so do not drive long distances before drift. Four-wheel drive car is clearly possible. After driving it? After the front-wheel drive is not driving force, but the front wheels can be placed at an angle to the sliding direction of the vehicle body, so the drive can drift long distances.
slip away before the start of the sliding speed related, usually more slippery slower, finally stopped, but if the venue permits, controlled, it is theoretically possible to make unlimited long skid. Because there is still a slipping wheel acceleration used, and the sliding resistance of the ground by the tires, when the balance of these two actions, the vehicle speed is not reduced. E.g. Donut (spinning around) is an infinitely long drift, of course, may be made infinite turning radius larger drift.
