Manual Transmission  A manual transmission, also known as a manual gearbox or standard transmission,  is a type of transmission used in motor vehicle applications. It uses a driver-operated clutch engaged and disengaged by a foot pedal (automobile) or hand lever (motorcycle), for regulating torque transfer from the engine to the transmission; and a gear stick operated by foot (motorcycle) or by hand (automobile).

The differential sits between the wheels, where the drive shaft connects with the axle. Depending on whether your vehicle is front-wheel drive, rear-wheel drive or four-wheel drive, the differential is on the front, rear or both axles. In addition to differentials , four-wheel drive cars have a transfer case .

The riding comfort and handling qualities of an automobile are greatly affected by the suspension system, in which the suspended portion of the vehicle is attached to the wheels by elastic members in order to cushion the impact of road irregularities. The specific nature of attaching linkages and spring elements varies widely among automobile models. The best rides are made possible by independent suspension systems , which permit the wheels to move independently of each other. In these systems the unsprung weight of the vehicle is decreased, softer springs are permissible, and front-wheel vibration problems are minimized. Spring elements used for automobile suspension members, in increasing order of their ability to store elastic energy per unit of weight, are leaf springs , coil springs, torsion bars, rubber-in-shear devices, and air springs.   Download Lecture Slides from the Following Link: Suspension system 1   Suspension system 2   Download suspension vide...
