Component identification

Component Identification

Chassis System Components

  • The chassis is the main supporting structure (frame) of a vehicle to which all other components are attached.
  • Suspension system refers to the collective name for all the parts that connect the vehicle to its wheels.
  • Steering system allows the driver to guide the vehicle.
  • Braking system slows or stops the vehicle by converting kinetic energy into heat.
  • Transmission system transmits power from the engine to the wheels.
  • Exhaust system directs harmful exhaust gases out of the vehicle.

Differentiating Between Components

  • Different components can be identified based on their location, function, and appearance.
  • Tyres are large, round, rubber components attached to the wheels and in contact with the road.
  • Brake discs are circular and metallic, located around the wheel hub.
  • The axle is a long metal component stretching between the wheels.
  • The gearbox—part of the transmission system—typically sits beneath the engine and is encased in a large metal housing.

Component Function

  • Tyres deliver traction and absorb road shocks.
  • Brake discs work together with brake pads to slow or stop the vehicle.
  • The axle bears the weight of the vehicle and its cargo, and also allows for the wheels to rotate.
  • The gearbox controls power output from the engine to the wheels, allowing for optimised performance at different speeds.

Key Component Features

  • Characteristics of different components can help in identification.
  • For instance, the gearbox is typically large and metallic with input and output shafts.
  • The brake disc usually shows evidence of wear from braking friction.
  • Tyres will have a tread pattern designed for optimised grip and water displacement.

Role of Components in Vehicle Operation

  • Understanding the role of each component in overall vehicle operation helps in identification.
  • For example, components related to movement—including the gearbox and axle—are part of the drivetrain.
  • Brake discs are part of the braking system and play a key role in vehicle safety.
  • Tyres play a critical role in vehicle movement, performance and safety.
  • Subsystems, like the exhaust system, help to safely get rid of waste products from the vehicle.
