How Do Car Gearboxes Work?


The main component of a transmission in a car is the gearbox. The gears that are in car gearboxes are made to activate or set in motion when the gearshift or the gear selector is activated. The gearbox in the car will provide the driver with gear reduction from a motor that is in high-speed to a much slower speed, but with a more powerful production system.

The car will propel forward when the gearbox converts the speed of the engine into torque. To give the car the maximum amount of torque and speed it needs, each category of the gears have a corresponding gear designed that works appropriately with the gears

Most often the gearboxes are designed to increase the torque while also reducing the speed of the drive-shaft of the engine in the car. This happens when the drive-shaft in the gearbox rotates at a much slower speed than the drive-shaft of the engine. Because of the reduction in speed, this will convert the energy produced into speed thrust, and this causes the drive-shaft of the gearbox to rotate producing more power, which leads to increased torque.

When it comes to manual transmissions in cars, the gearbox design is much simpler and requires the manual movement of a sliding gear, which is the main shaft of the gearbox and uses a shifter to change gears. The gear lever and the shifter are attached, which allows the sliding gear to move. When the clutch is activated, the sliding gear will disengage out of the existing position and will slide along the gearbox to reengage in a lower or higher gear.

The most modern manual gearboxes will have a diagonal gear design, and they will sit alongside the main gears of the car. This ensures that the sliding gear is coordinated with the main gears of the car. This coordination allows the sliding gear to effortlessly engage with the rest of the main gears. This will prevent the gears from conflicting with each other and causing damage to the transmission.

With automatic gearboxes, it is similar to a manual gearbox only that the transmission system will select the appropriate gear automatically. The driver will not have to shift the gears; it will do it on its own. There is a hydraulic system in the automatic gearbox, and it will detect the pressure of the fluids in the engine to select the proper gear for the car. With an automatic gearbox, it will use a torque converter rather than a clutch.
