In a few of the latest cars out there, you can change gears simply by pressing a button, turning a knob or toggling a little joystick. Yet at the same time, Variable Speed Drive Motor plenty of different vehicles still require drivers to use one foot for the clutch pedal and another for the gas, all while using one hand to manipulate the gear-change lever through a definite design of positions. And several other current cars don’t have any traditional gears at all in their transmissions.

But whether or not a vehicle includes a fancy automatic, an old-college manual or a modern-day consistently variable transmitting (CVT), each unit has to do the same work: help transmit the engine’s output to the traveling wheels. It’s a complicated task that we’ll make an effort to make a little simpler today, starting with the basics about why a tranny is needed in the first place.
Let’s actually begin with the typical internal combustion engine. As the fuel-air mix ignites in the cylinders, the pistons begin upgrading and down, and that movement can be used to spin the car’s crankshaft. When the driver presses on the gas pedal, there’s more fuel to burn in the cylinders and the whole process moves faster and faster.

What the transmission does is change the ratio between how fast the engine is spinning and how fast the driving wheels are moving. A lesser gear means optimum functionality with the wheels moving slower than the engine, while with an increased gear, optimum performance includes the wheels moving quicker.
With a manual transmission, gear shifting is handled by the driver via a gear selector. A lot of today’s vehicles have got five or six ahead gears, but you’ll discover older models with from three to six forward gears offered.

A clutch is used to transmit torque from a car’s engine to its manual tranny. The various gears in a manual tranny allow the car to visit at different speeds. Larger gears offer plenty of torque but lower speeds, while smaller gears deliver much less torque and allow the car travel quicker.
