What is the function of the kingpin inclination angle?
1 Answers
The function of the kingpin inclination angle is: The kingpin inclination angle enables the vehicle's wheels to automatically return to the straight position after steering. The larger the inclination angle, the stronger the self-centering effect, but it makes steering the wheel more laborious and increases tire wear. It also facilitates easier steering. Below is relevant information: 1. The kingpin inclination angle refers to the acute angle formed by the projection of the vehicle's steering knuckle kingpin axis (or the connecting line between the upper and lower ball joint centers of an independent suspension) and the vertical line on a plane perpendicular to the vehicle's longitudinal symmetry plane. When viewing the tire from the front or rear of the vehicle, the kingpin axis tilts inward toward the vehicle 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 vehicle are lifted to a corresponding height. This creates an effect where the vehicle's own gravity helps the steering wheel return to its original straight position, making it easier to reset the steering wheel.
