What is the function of the kingpin inclination angle?
1 Answers
The function of the kingpin inclination angle is: The kingpin inclination angle allows the car wheels to automatically return to the straight position after steering. The larger the angle, the stronger the return effect, but the harder it is to turn the steering wheel, and it increases tire wear. It also makes steering easier. Below is relevant information: 1. The kingpin inclination angle refers to the acute angle formed by the projection of the car's steering knuckle kingpin axis (or the connecting line between the upper and lower ball joints of an independent suspension) and the vertical line on a plane perpendicular to the vehicle's longitudinal symmetry plane. When viewed from the front or rear of the car, the kingpin axis tilts inward towards the body, and this angle is called the kingpin inclination angle. 2. When the wheel rotates around the kingpin, the lowest point of the wheel would theoretically sink below the road surface. However, in reality, the lower edge of the wheel cannot sink below the road surface. Instead, the steering wheel and the entire front part of the car are lifted to a corresponding height. This effect causes the car's own gravity to help the steering wheel return to its original central position, making it easier to reset the steering wheel.
