In some of the newest cars out there, you can shift gears simply by pressing a button, turning a knob or toggling a small joystick. Yet simultaneously, plenty of different automobiles still require motorists to make use of one foot for the clutch pedal and another for the gas, all while using one hand to control the gear-change lever through a definite design of positions. And many other current cars don’t possess any traditional gears at all within their transmissions.
But regardless of whether a vehicle includes a fancy automatic, an old-school manual or a modern-day continuously Variable Speed Drive Motor variable transmitting (CVT), each unit has to do the same work: help transmit the engine’s output to the traveling wheels. It’s a complex task that we’ll make an effort to make a little simpler today, you start with the basics about why a transmitting is needed in the first place.
Let’s actually start with the typical internal combustion engine. As the fuel-air mixture 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 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 overall performance 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. Many of today’s cars possess five or six forward gears, but you’ll find older models with from three to six ahead gears offered.
A clutch is utilized to transmit torque from a car’s engine to its manual transmitting. The various gears in a manual tranny allow the car to travel at different speeds. Bigger gears offer lots of torque but lower speeds, while smaller gears deliver much less torque and invite the car travel more quickly.
