Getriebekühlung

Getriebekühlung refers to the systems and methods used to manage the temperature of a transmission in a vehicle or machinery. Transmissions, especially automatic transmissions, generate significant heat during operation due to friction between moving parts and the viscosity of the transmission fluid. Excessive heat can degrade the transmission fluid, leading to reduced lubrication, increased wear, and potential component failure.

Common Getriebekühlung systems involve circulating transmission fluid through a heat exchanger, often referred to as a transmission cooler. This cooler can be integrated into the vehicle's main radiator (a "radiator-type" cooler) or be a separate unit mounted in front of the radiator, exposed to airflow (an "auxiliary" or "stand-alone" cooler). As the hot transmission fluid flows through the cooler, it transfers its heat to the surrounding air or coolant, thereby lowering the fluid's temperature.

The cooling system may also include a thermostat to regulate fluid flow, ensuring optimal operating temperatures. In some high-performance applications or heavy-duty vehicles, electric fans might be employed to enhance cooling efficiency when the vehicle is stationary or moving at low speeds. Proper Getriebekühlung is crucial for extending the lifespan and maintaining the performance of the transmission.
