Define an “axle” of a vehicle:
- The vehicle’s back beam to which the vehicle’s spare wheel is connected.
- A shaft which transmits the rotary motion from the gearbox to the engine.
- Correct answer: Shaft or system of shafts running the width of the vehicle attached to the wheels.
- The vehicle’s front part, designed to absorb the impact of low-speed collisions
Why this is the answer
The correct answer in the official bank: Shaft or system of shafts running the width of the vehicle attached to the wheels.
An axle is a shaft or system of shafts running across the width of the vehicle, on which the wheels are mounted on both sides of the vehicle. In a heavy vehicle and a bus it is important to know this term, because the number of axles and the permitted weight on each axle affect the load and safety. The front part designed to absorb light impacts is the bumper, not the axle.
