SUMMARY

The self-correcting behavior of the steering wheel in vehicles is primarily due to the inertial effect and the caster angle of the front tires. The caster angle, which is the angle of the pivot axis, is designed so that the contact patch of the tires is positioned behind this axis. This configuration generates a steering torque during cornering that naturally returns the steering wheel to its neutral position. Understanding these dynamics is essential for grasping vehicle handling characteristics.

PREREQUISITES
  • Understanding of vehicle dynamics
  • Knowledge of caster angle and its effects
  • Familiarity with steering systems in automobiles
  • Basic physics principles related to inertia
NEXT STEPS
  • Research the effects of caster angle on vehicle stability
  • Explore the principles of vehicle dynamics in detail
  • Learn about different steering system designs and their characteristics
  • Investigate the role of tire contact patches in vehicle handling
USEFUL FOR

Automotive engineers, mechanics, driving instructors, and anyone interested in understanding vehicle handling and dynamics.

Why the steering wheel comes back to its main position automatically to some extent after the car has been turned...??

Inertial effect. Car wants to go in straight line.
 
The front tires have caster, meaning that the pivot axis is angled and/or offset so that the contact patch is "behind" the pivot axis, and the side load due to cornerning creates a steering torque on the tires that tends to center the steering.
