A Simple Explanation of How A Transmission System Works – Part III of III

Transmission Operation Diagram

Double-clutch

Double-clutching was a common clutch mechanism in older automobiles and is used in some race cars even today. Initially, you push the clutch pedal and de-couple the engine and the transmission. The collar, thus, goes into neutral because there is no pressure on the dog teeth. When you take your foot off the pedal, the engine is connected to ensure you have the right speed. To engage the dog teeth, the next gear and the collar have to rotate at the same speed. When this is achieved, you push the pedal again and lock the collar to a new gear. This process of pushing the clutch twice at every gear change is called double-clutching.

Synchronizer

Modern transmissions eliminate the need for double-clutching by using synchronizers. A synchronizer enables frictional contact of the collar and gear before engaging the dog teeth. Thus, the speed is synchronized before the dog teeth make contact voiding the double-clutch.

Manual transmissions are simple, cost-effective, lightweight, and more efficient than the automatic. But the automatic transmission allows you to have a hassle-free drive without having to worry about changing gears. The communication between the numerous components is what drives the transmission system. It is remarkable how a few simple twists and draws can put your vehicle into motion and control its speed.

The design and implementation of transmissions vary from one manufacturer to another. The overall mechanism, however, remains the same.
