Torque is supplied from the engine, via the transmission, to a drive shaft (British term: ‘propeller shaft’, commonly and informally abbreviated to ‘prop-shaft’), which runs to the final drive unit that contains the differential. A spiral bevel pinion gear takes its drive from the end of the propeller shaft, and is encased within the housing of the final drive unit. This meshes with the…

The differential is found on all modern cars and trucks, and also in many all-wheel-drive (full-time four-wheel-drive) vehicles. These all-wheel-drive vehicles need a differential between each set of drive wheels, and they need one between the front and the back wheels as well, because the front wheels travel a different distance through a turn than the…

Advantages of Rear Wheel Drive- 1.    Better handling in dry conditions – accelerating force is applied to the rear wheels, on which the down force increases, due to load transfer in acceleration, making the rear tires better able to take simultaneous acceleration and curving than the front tires. 2.    More predictable steering in low traction conditions (ie: ice or gravel) because the steering…

Advantages of Front Wheel Drive- 1.    Interior space: Since the powertrain is a single unit contained in the engine compartment of the vehicle, there is no need to devote interior space for a driveshaft tunnel or rear differential, increasing the volume available for passengers and cargo. 2.    Cost: Fewer components overall 3.    Weight: Fewer components mean lower weight 4.    Fuel economy: Lower weight means…

A differential is a device, usually, but not necessarily, employing gears, capable of transmitting torque and rotation through three shafts, almost always used in one of two ways: in one way, it receives one input and provides two outputs—this is found in most automobiles – and in the other way, it combines two inputs to create an output…

It is a device for transmitting rotation between shafts by means of the acceleration and deceleration of a hydraulic fluid (such as oil). Also known as hydraulic coupling. Structurally, a fluid coupling consists of an impeller on the input or driving shaft and a runner on the output or driven shaft. The two contain the…

Friction Clutch Friction clutches are the most commonly used clutch mechanisms. They are used to transmit torque by using the surface friction between two faces of the clutch. Dog Clutch A dog clutch couples two rotating shafts or other rotating components not by friction, but by interference. Both the parts of the clutch are designed…

·         It should be able to transmit the maximum torque of the engine. ·         It should engage gradually to avoid sudden jerks. ·         It should be able to dissipate a large amount of heat generated during clutch operation. ·         It should be dynamically balanced, particularly in the case of high-speed engine clutches. ·         It should have a suitable mechanism to…

A Clutch is a machine member used to connect the driving shaft to a driven shaft, so that the driven shaft may be started or stopped at will, without stopping the driving shaft. A clutch thus provides an interruptible connection between two rotating shafts. Clutches allow a high inertia load to be stated with a small power. Clutches…

Air Brake System is the brake system used in automobiles such as buses, trailers, trucks, and semi-trailers. George Westinghouse created air brakes for utilizing it in trains for railway service. A secured air brake was patented by him on 5th, March 1872. At first air brake is produced for use on trains and now it is…
