These are the reactions of a vehicle that are often misunderstood or not correctly interpreted Oversteer and Understeer. For this reason, tuningblog clarifies something in the following article.
What is oversteer?
The Oversteer represents a physical reaction of the car that occurs during the Cornering occurs. Oversteering causes the rear of the vehicle to slip away, with the slip angle of the rear wheels being greater than that of the front wheels. When it comes to putting this reaction into words, many drivers refer to the vehicle's behavior as spongy or lose. By the way, we call it Drift, but that's another topic ^^. But how can a car actually oversteer? For example, one of the most common reasons is too much Gas give during and / or too much Speed when driving through the curve. Especially for rear-wheel drive vehicles. In most cases, it is helpful to take back the steering movement and to take off the gas at the same time. Also subtle Countersteering can help until the situation "normalizes" again. vehicles with ESP / traction control hardly tend to break out in the curve.
What is understeer?
As for slip angle, when understeering is,,,,, of the front wheels greater than the one with the rear wheels - exactly the other way compared to oversteering. In this case one speaks of "pushing". This is because many have the feeling that the car is literally being pushed outwards by the front wheels within the curve. This effect is further intensified when further accelerated what the resulting load change (Front to rear axle) underlying.
The best way to counteract understeer is to keep your foot slightly takes off the gasbecause the weight is shifted to the front wheels. The front wheels now adhere better again, instead of sliding friction there is now static friction. As standard, most vehicles tend to understeer. If you feel uncomfortable and take your foot off the gas, the front wheels turn more strongly, which is considered safer and also easier to control. When the car leans in the curve, the suspension on the is compressed outer Side of the curve, which in turn is the spring of the inner Side relieved. The suspension on the outside moves in the compression direction and that on the inside in the pulling direction.
Vehicle damping - tuning tips
By using the rebound damping force of the front inner Increase the shock absorber, the main load when cornering is on the behind lying outer Dampers. This gives you more stability and directional stability when exiting a curve. The dampers installed in the front have the main influence on the handling when exiting a curve. The rebound damping force of the rear inner shock absorber increase, results in the car leaving the curve over the one in front outer damper unrolls. If you have the rebound damping force of both built in front Increasing the dampers results in a tighter overall driving behavior. The exact opposite is in increasing the rebound damping force of the two rear Damper the case.
However, you should always remember that it not the weight changes when the load changes by adjusting the rebound damping force. The load change is only here delayed. In addition, you should only make such adjustments to the extent that bad driving characteristics be eliminated. If the changes are too great, in the worst case scenario, this can lead to more devastating handling problems!
