Study Notes

Steering Principle

The steering system in automobiles enables the vehicle to change direction by turning the wheels
It involves the conversion of rotary motion of the steering wheel into linear motion of the wheels
The steering system is crucial for safe and efficient vehicle operation

Suspension Systems

Suspension systems absorb shocks and vibrations, providing a smooth ride and maintaining vehicle stability
Types of suspension systems:
- Leaf spring suspension: uses a longitudinal leaf spring to absorb shocks
- Coil spring suspension: uses a coil spring to absorb shocks
- Torsion bar suspension: uses a torsion bar to absorb shocks
- Air suspension: uses compressed air to absorb shocks

Braking System

The braking system slows or stops the vehicle by converting kinetic energy into heat energy
Key components of a braking system:
- Brake pedal: actuates the braking system
- Master cylinder: converts non-hydraulic pressure into hydraulic pressure
- Brake caliper: houses the brake pads and applies pressure to the rotor
- Brake rotor: rotates with the wheel and is slowed by the brake pads
- Brake pads: convert kinetic energy into heat energy

Wheels and Tires

Wheels are metal rims that support the tires and rotate with the vehicle
Tires are the rubber components that contact the road and provide traction
Key specifications of wheels and tires:
- Wheel diameter and width
- Tire size and type (e.g. radial, bias-ply)
- Tire pressure and load-carrying capacity
