所谓卡姆圆其实就是 轮胎附着力 的一种简单表现形式。 如图1所示，假设一只轮胎可以提供的抓地力为一个卡姆圆，当我们正常行驶时，单独的前后驱动力和侧向驱动力都包含在卡姆圆内，此时轮胎可以提供有效附着力，促使车辆正常形式；而如果当正向和侧向的两个驱动力的合力超出卡姆圆时，轮胎则超出了所能承受的极限，发生失控。 我们平时所看到了漂移表演都属于这种情况。 卡姆圆，汽车在单一前进的时候，受到了前进的：摩擦力，而车辆进行转弯的时候，则出现了另 …

The circle of forces, traction circle, friction circle, [1] or friction ellipse[2][3][4] is a useful way to think about the dynamic interaction between a vehicle's tire and the road surface. The diagram below shows the tire from above, so that the road surface lies in the xy - plane.

2025年2月7日 · Kamm’s Circle 是一种用于描述车辆侧向动力学的图形工具，主要用于分析车辆在不同侧向加速度下的轮胎侧向力和侧向滑移角的关系。 定义 ： Kamm’s Circle 是一个以车辆侧向加速度为半径的圆，表示在给定的侧向加速度下，轮胎侧向力的最大可能值。

2015年1月1日 · The tire forces at the point of contact (tires–road) are responsible for changing direction; actuators readjust them. The frictional coefficient μ and the contact force F z, both parameters of the Kamm circle, define the limits for the maximum horizontal tire forces at …

Friction circle (based on the assumption that a tire can develop equal limiting longitudinal and lateral forces) gives you: - The maximum longitudinal force that the tire can develop while it...

2018年2月23日 · 上圖為輪胎的合力圓（Kamm Circle），為了方便理解我們可以假設在一個條件下，輪胎的最大的抓地力是 10，也就是圖一中黃色圈的合力圓，機車如果要安全行駛在道路上，則其縱向力（因為加速／煞車）與橫向力（因為轉彎）相加起來的合力必須在 10 以下，一旦 ...

The circle is named Kamm circle and represents the maximum total friction force that can applied in the contact patch. If the driver only brakes, in straight line, all the available friction force will be used in longitudinal direction Xw, to slow the vehicle down. If the braking force exceeds this limit, the wheel will lock and slip.

Friction Circle Theory (Kamm) This theory about the transferable forces from the tire to the road surface goes back to Wunibald Kamm. After several years of activities at Daimler and other industries, he founds the Research Institute of Automotive Engineering and aircraft engines at the Technical University of Stuttgart, as it was named in the ...

The thing is called "Kamm's Circle" - it is just phyiscs but it is simple to understand. Have a look: Centrifugal forces are built up in every steering manoeuvre while driving, then being absorbed again by the lateral guidance forces in the wheels. Kamm's Circle is a model illustrating the distribution of forces on the wheels and the connection ...

2021年9月11日 · This can be illustrated by using the so called Kamm circle of friction. Refer to the figures below of a vehicle accelerating forward (up in the figure) and cornering to the right. $F_{Lat}$ is the centripetal force and $F_{Lon}$ is the tangential force.
