Zorluk: OrtaSkid Control and Recovery

A loaded semi-truck navigating a wet interstate curve experiences a sudden drive-wheel skid as the rear of the tractor swings out toward the right shoulder. What is the correct initial procedure to regain directional control?

  1. A
    Steer sharply to the left away from the sliding direction while maintaining engine power.
  2. B
    Switch on the engine brake retarder to maximum setting to slow the drive axle.
  3. Release the accelerator, depress the clutch pedal, and steer right toward the direction the rear wheels are sliding.Cevap
  4. D
    Apply firm and continuous service brakes to force the vehicle to an abrupt halt.

Cevap

The driver must release the accelerator, depress the clutch, and steer toward the right in the direction of the skid.
Releasing the accelerator removes driving torque from slipping drive wheels, and depressing the clutch allows the wheels to roll freely. Steering into the skid (to the right when the rear slides right) realigns the front and rear wheels, enabling the tires to regain traction and arrest the slide.

Adım Adım Çözüm

1
Remove foot from accelerator and depress the clutch pedal.
Disengages driveline torque and mechanical braking from drive wheels.
The drive wheels must be allowed to roll freely so they can regain traction with the road surface.
2
Steer toward the right in the direction the rear of the vehicle is sliding.
Realigns the tractor's front wheels with the path of the sliding rear axle.
Turning in the direction of the skid arrests lateral momentum and prevents the vehicle from spinning out.
3
Counter-steer back smoothly as the vehicle comes back in line.
Stabilizes the vehicle along its intended trajectory.
Failing to counter-steer once traction is regained causes a secondary skid in the opposite direction.
