The reason why should four-wheel drive opel tech2 on the last to say that because of the type of four-wheel drive, performance vary. Its English name is a 4 Wheel Drive. Purposes can be divided into two types: road four-wheel drive and off-road four-wheel drive. From
the sub-type of actuator can be divided into four kinds: full-time
four-wheel drive, time 4WD, timely four-wheel drive and ultra-election
four-wheel drive.
First
of all, we come to understand as road four-wheel drive, four-wheel
drive high-speed driving on the highway will bring any benefit. Usually
we common two driver, whether it is the precursor or rear-wheel drive,
the output power of the engine is borne by two wheels, which means each
wheel is to bear 50% of the drive force. Each
of the wheels of the four-wheel-drive models get a power of 25%, which
means that each wheel assumed torque output is reduced by half. Then
in the case of the same engine power, the four-wheel drive models than
two driven due to the power output of each wheel borne small, so the
probability of slip is reduced. Larger effective traction can be
opcom op com obtained in the acceleration.
Equipped with a high-power engine saloon cars like four-wheel drive to increase the output of effective traction. Audi assembly of more than 8-cylinder engine models are equipped with a full-time four-wheel drive to get better power. The Benz E BMW5 system the four-wheel drive version. Of
course, the improvement of the effective traction and a greater benefit
is that you can enhance the vehicle's climbing performance. The
center of gravity moved the car uphill, the front wheel load decreases,
so very easy to slip before the drive even after the drive, and can
lead to tire easily slip due to positive pressure decreases uphill tire
adhesion reduce. Each
of the wheels of the four-wheel drive models bear only about 25% of the
power, so the chance to reduce skidding, climbing performance improved
significantly.
As
off-road four-wheel drive, as mentioned above, in addition to climbing
performance can improve off-road, non-road conditions through
performance. In
fact, it is easy to understand, the ordinary two-wheel drive car, if
the drive wheels the mire slip, the whole car lost power. The
four wheels can provide traction, then the two wheels after falling
into the quagmire of the other two wheels include the
ford vcm ids ability to provide
traction and allow the car to get rid of the plight of the anchored.
