What are the effects of excessive or insufficient kingpin inclination angle?
1 Answers
An insufficient kingpin inclination angle will cause the vehicle to drive unstably, while an excessive kingpin inclination angle will result in heavy steering. Below are additional details: 1. Abnormal kingpin inclination: If the kingpin inclination becomes abnormal due to reasons such as deformation of the spring steel plate, bending or twisting of the I-beam, or deformation of the frame, it will significantly affect the stability of the vehicle's steering wheels. When the steering kingpin inclination angle is set too small, turning the steering wheel becomes very easy, especially at lower speeds, thereby losing the stabilizing effect of the kingpin inclination. Steering stability can only be maintained by the kingpin inclination, making it easy to lose control during vehicle braking. 2. Load on the vehicle's front axle: When returning to straight-line driving, the steering wheel may feel too light or too abrupt, causing the steering wheels to wobble. Therefore, when selecting the inclination angle, it should be based on the specific condition of the vehicle, rather than solely relying on the original wedge piece of the kingpin inclination angle. Often, when repairing old vehicles, their frames, front leaf springs, front beams, and other major components may have deformations or inaccuracies.
