variable speed transmission

In some of the most recent cars out there, you can change gears by simply pressing a button, turning a knob or toggling a small joystick. Yet simultaneously, plenty of different vehicles still require drivers to make use of one foot for the clutch pedal and another for the gas, all while using one hand to control the gear-shift lever through a definite pattern 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-school manual or a modern-day continually variable transmission (CVT), each unit has to do the same job: help transmit the engine’s output to the traveling wheels. It’s a complicated task that we’ll try to make a little simpler today, you start with the fundamentals about why a transmission is needed in the first place.
Let’s actually begin with the normal internal combustion engine. As the fuel-air mix ignites in the cylinders, the pistons start moving up and down, and that motion is utilized to spin the car’s Variable Speed Transmission crankshaft. When the driver presses on the gas pedal, there’s more fuel to burn off in the cylinders and the whole 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 lower gear means optimum overall 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 via a gear selector. Many of today’s vehicles possess five or six forwards gears, but you’ll discover older models with from three to six forwards gears offered.

A clutch can be used to transmit torque from a car’s engine to its manual transmission. The many 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 much less torque and allow the car travel more quickly.
