In some of the latest cars in the marketplace, you can change gears simply by pressing a button, turning a knob or toggling a little joystick. Yet simultaneously, plenty of different automobiles still require motorists to use one foot for the clutch pedal and another for the gas, all when using one hand to manipulate the gear-change lever through a distinct design of positions. And several other current vehicles don’t possess any traditional gears at all in their transmissions.
But regardless of whether a vehicle includes a fancy automatic, an old-college manual or a modern-day continually variable transmitting (CVT), each unit has to do the same job: help transmit the engine’s result to the generating wheels. It’s a complicated task that we’ll make an effort to make a bit simpler today, starting with the fundamentals about why a tranny is needed in the first place.
Let’s actually begin with the typical internal combustion engine. As the fuel-air blend ignites in the cylinders, the pistons begin moving up 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 quicker and faster.
What the transmission does is change the ratio between how fast the Variable Speed Drive Motor engine is spinning and how fast the driving wheels are moving. A lesser gear means optimum overall performance with the wheels moving slower compared to the engine, while with an increased gear, optimum performance comes with the wheels moving quicker.
With a manual transmission, gear shifting is handled by the driver via a gear selector. A lot of today’s cars have got five or six ahead gears, but you’ll discover older models with anywhere from three to six ahead gears offered.
A clutch can be used to transmit torque from a car’s engine to its manual transmitting. The various gears in a manual transmitting allow the car to travel at different speeds. Bigger gears offer plenty of torque but lower speeds, while smaller gears deliver less torque and allow the car travel more quickly.
