This lesson introduces the fundamental components that connect a vehicle to the road: the wheels and tyres. In Ghana, where road conditions can be challenging and vehicle maintenance is crucial for safety and business, understanding these parts is not just an academic exercise—it's a vital life skill. From the family car to the tro-tro or the cargo truck, every vehicle relies on its wheels and tyres. This lesson will break down their functions, types, and the important information written on them, empowering learners to make safer and more informed decisions about transportation.
A. The Vehicle Wheel
The wheel is the strong, circular metal component that the tyre is mounted on. It has three primary functions: Supports the vehicle's weight: It bears the entire load of the vehicle. Transfers power: It transfers the driving and braking forces from the axles to the tyres. Connects to the vehicle: It provides a mounting point (the hub) to attach to the vehicle's suspension system.
Parts of a Wheel: A typical wheel consists of two main parts joined together: the rim and the disc/spider. Rim: The outer edge of the wheel where the tyre is seated. It has a specific shape with "bead seats" to hold the tyre securely. Disc (or Spider): The central part of the wheel that connects the rim to the axle hub. The bolt holes for the lug nuts are in the disc. Hub: The very centre of the disc, which fits over the vehicle's axle.
*(Teacher's Note: Use a diagram or a real wheel to point out these parts.)*
