What is the function of the kingpin inclination angle at the tire?

[DeHaley]

The functions of the kingpin inclination angle at the tire are: 1. Automatic return of the front wheels, making steering operation easier and reducing the impact force on the steering wheel; 2. Maintaining the stability of the vehicle's straight-line driving; 3. Making steering more effortless for the driver. The kingpin inclination angle refers to the acute angle of the projection, on a plane perpendicular to the vehicle's longitudinal symmetry plane, of the connecting line between the centers of the upper and lower swing arm ball joints of a vehicle or independent suspension with respect to the vertical line. The functions of the tire are: 1. Supporting the entire weight of the vehicle and bearing the load; 2. Transmitting traction and braking torque, ensuring the adhesion between the wheel and the road surface; 3. Reducing and absorbing vibrations and impact forces during driving, preventing severe vibrations and premature damage to vehicle components; 4. Adapting to the high-speed performance of the vehicle and reducing driving noise, ensuring driving safety, handling stability, and comfort.
