Synchronized Transmission

Manual transmissions in modern passenger cars use synchronizers to eliminate the need for double-clutching. A synchro’s purpose is to allow the collar and the gear to make frictional contact before the dog teeth make contact. This lets the collar and the gear synchronize their speeds before the teeth need to engage as shown in figures….

Double Clutching

Double-clutching is a driving technique solely used in manual transmission vehicles. Double-clutching was common in older cars and is still common in some modern Race Cars.  To understand how it works, the most important thing to know is that there are three systems involved: the engine, the clutch, and the transmission. Your engine produces power, the…

Working of Manual Transmission

When you start a manual transmission car, before you turn the key, you disengage the clutch by pressing down on the clutch pedal. This disconnects power flow between the engine’s input shaft and transmission. This allows your engine to run without delivering power to the rest of the vehicle. With the clutch disengaged, you move the gearshift into first gear….

Manual Transmission

The first transmission invented was the manual transmission system. A manual transmission, also known as a manual gearbox or standard transmission (informally, a “manual”, “stick shift”, “straight shift”, or “straight drive”) is a type of transmission used in motor vehicle applications. It generally uses a driver-operated clutch, typically operated by a pedal or lever, for regulating torque transfer…

Need For a Transmission

The need for a transmission in an automobile is a consequence of the characteristics of the internal combustion engine. Engines typically operate over a range of 600 to about 7000 revolutions per minute (though this varies, and is typically less for diesel engines), while the car’s wheels rotate between 0 rpm and around 1800 rpm. Furthermore,…
