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.
