Of course it is :) It's nice-nicer-nicest. And remember-there's no such thing as a real word.. If a word is used and people understand it, then it is just as real â¦ as any word in any dictionary, or any word approved by your English teacher!
In British English, the term drive shaft is restricted to a transverse shaft that transmits power to the wheels, especially the front wheels. A drive shaft connecting the gearbox to a rear differential is called a propeller shaft, or prop-shaft. A prop-shaft assembly consists of a propeller shaft, a slip joint and one or more universal joints.
The engine is rigidly mounted, but the propellor shaft must be flexible to allow for movement of the back axle. In a front-engined rear-wheel-drive car, power is transmitted from the engine through the clutch and the gearbox to the rear axle by means of a tubular propeller shaft. The rear axle must be able to move up and down on the suspension according to variations of the road surface.
