The Gearbox is an interactive puzzle kit to help learn and better understand the working and principles of a 4- speed manual Gearbox.

A mechanical gearbox is a reducer that provides speed and torque conversions from a motor to the driving wheels.

After assembly, you can experiment with the Ugears manual Gearbox, by turns, choose I, II, III, or reverse with a kinematic pair of gears with different ratios and, rotating the actuator handle clock-wise, you can watch and control the rotation speed of the layshaft and drive shaft. In the Position “N” – idle in which both clutch gears of layshaft remain uncoupled and idling; the First Gear makes the layshaft and gears rotate with the lowest speed; the Second Gear lets the drive shaft along with the flywheel rotate with an average speed and the Third Gear allows the layshaft and all gears rotate with the highest speed. Switch on the Reverse gear and see how the driving clutch gear moves to the left towards gear “R” and connects to it transferring the rotation to the lower gear arrangement and propelling the layshaft and all gears to rotate in reverse.

When and who invented it
The invention of the gearbox belongs to the famous German engineer Karl Benz.

Usage
A gearbox is mainly used in the automobile industry as a part of the car transmission mechanism that transfers torque from the engine’s shaft to the wheels.
