käigupõhised

Käigupõhised is an Estonian term that translates to "gear-based" or "transmission-based" and is commonly used in the context of mechanical systems, particularly vehicles. It refers to a system where power is transmitted and controlled through a series of gears. This is most frequently encountered in the operation of transmissions, both manual and automatic, in automobiles and other machinery.

In a vehicle's transmission, käigupõhised describes the mechanism by which different gear ratios are selected to alter the torque and speed delivered to the wheels. This allows the engine to operate within its optimal power band across a range of driving conditions, from starting from a standstill to maintaining high speeds. Manual transmissions require the driver to actively select gears, often using a clutch pedal and a gear stick, while automatic transmissions handle this process autonomously.

The concept of käigupõhised extends beyond automotive applications. It can be found in various industrial machines, bicycles, and any mechanical device that requires controlled power transmission through rotating elements. The design and implementation of käigupõhised systems are crucial for efficiency, performance, and durability of the machinery they are part of. Understanding the principles of gear ratios, meshing, and lubrication is fundamental to the engineering of these systems.
