Study Notes
Primary Functions of Running Gear
- The primary functions of the running gear of a ground vehicle include supporting the vehicle's weight, transmitting traction and braking forces to the ground, and stabilizing the vehicle's motion.
Forces and Moments Affecting Motion
- The major forces and moments affecting the motion of a ground vehicle, aside from aerodynamic and gravitational forces, are applied through the running gear and include vertical loads, longitudinal traction forces, lateral cornering forces, and rolling resistance.
Importance of Running Gear-Ground Interaction
- An understanding of the interaction between the running gear and the ground is essential because it affects the vehicle's performance, safety, and efficiency.
Tires in Road Vehicles
- Tires are universally used in road vehicles due to their ability to provide a flexible, adaptable interface between the vehicle and the ground.
Essential Functions of Tires
- The essential functions that tires are generally required to fulfill in the running gear of a ground vehicle include:
- Supporting the vehicle's weight
- Providing traction and braking forces
- Absorbing shock and vibrations
- Maintaining directional stability
- Withstanding vertical and lateral forces
Key Function of Tires
- The key function of tires in ground vehicles is to provide a flexible, adaptable interface between the vehicle and the ground, enabling the transfer of forces and moments while maintaining traction and stability.
