In a few 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-shift lever through a distinct pattern of positions. And several other current vehicles don’t have any traditional gears at all in their transmissions.
But regardless of whether a vehicle has a fancy automatic, an old-school manual or a modern-day continuously variable transmitting (CVT), each unit must do the same job: help transmit the engine’s output to the generating wheels. It’s a complex task that we’ll make an effort to make a bit simpler today, you start with the basics about why a transmission is needed in the first place.
Let’s actually start with the normal internal combustion engine. As the fuel-air mixture ignites in the cylinders, the pistons begin upgrading and down, and that motion is utilized to spin the car’s crankshaft. When the driver presses on the gas pedal, there’s more fuel to burn off in the cylinders and the complete process moves quicker 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 performance with the tires moving slower compared to the engine, while with a higher gear, optimum performance comes with the wheels moving quicker.
With a manual transmission, gear shifting is handled by the driver with a gear selector. Many of today’s cars have got five or six Variable Speed Drive Motor forward gears, but you’ll find older models with from three to six forward gears offered.
A clutch can be used to transmit torque from a car’s engine to its manual tranny. The many gears in a manual transmission allow the car to visit at different speeds. Bigger gears offer plenty of torque but lower speeds, while smaller sized gears deliver much less torque and invite the car travel more quickly.
