★ What is understeering and oversteering
The understeer of undercarriage vehicles is often understeered. The performance is that the actual steering angle of the aerial working vehicle in the bend is smaller than that of the front wheel, that is, the front wheel has appeared to the outside. The steering is excessively known as the tail flick. The actual turning angle of the work vehicle in the curve is larger than that of the front wheel, that is, the rear wheel has moved to the outside.
★ Causes of understeer and oversteer
There are many factors that cause under-steering or over-steering in high-altitude vehicles. The resulting adhesion of tyres and roads is a constant value. Changes in centrifugal force and driving force will cause changes in resultant forces. When the resultant force is greater than the adhesion force, the tires It will slide along the direction of the force. If this tire is on the front wheel, then there will be understeer. If this tire is on the rear wheel, then there will be oversteer.
