Description: Friction drives are transmission systems that use friction to transfer power. The simplest form consists of two shafts with rotationally symmetrical Rolling elements that roll against each other. High-performance metallic components are kept apart by films of lubricant. Transmission can be varied via the rolling radii of the friction gears due to their conical shape, which also ensures that the Friction-based connection is not broken. Friction gears are used as continuously variable transmission systems. The disadvantage to these systems is that, unlike mechanically interlocking alternatives, they exhibit slip to a greater or lesser degree. This reduces their efficiency. However, there is no need for switching pauses due to missing switching stages. The drive always runs with the best fuel economy at any one time and lowest emissions. In certain designs, there is no need for a starting clutch. Since slippage occurs when the system is overloaded, a safety Clutch is automatically integrated into friction drives.
