Motor car chasis, 1904.
© Science Museum / Science & Society Picture Library
Working model (scale 1:14) of a stripped down chasis illustrating the car's components. Powered by its engine, the motor car relies on its transmision system to transfer the engine's power to the driving wheels. The transmision system includes most of the car's components: clutch, gearbox, universal joint, drive shaft, differential and half shafts. The car's braking ability comes from a series of levers and brake drums linked together by rods. This early car is also equipped with a cooling system and an exhaust system.
