Special solutions for temperature simulation in electromobility
Over the coming decade, CO2 limit values will be increasingly tightened in important automotive markets. The fact that both legal requirements and customer preferences vary from country to country means that the new electromobility business unit of the automotive and industrial supplier Schaeffler is working with a variety of different drive solutions. Schaeffler has achieved great market success with double clutch and hybrid modules for hybrid vehicles in which the electrical drive is located between the combustion engine and the transmission. The automotive supplier is reacting to the greater susceptibility that electric drives have to failure when compared to combustion engines by carrying out tests under extreme temperature conditions.
In order to be able to guarantee proper and durable functioning of separating clutches, for example, the components need to be subjected to endurance testing under environmental conditions that are as realistic as possible and also to fluctuating extreme temperatures. At the same time, during the tests there is also temperature measurement, measurement of drag torque at various temperatures and functional measurements.
