Method for determining spring pre-stress at spring-bearing-arrangement for balancing thermal conditioned position changes in motor car-axle drive, involves measuring spring force after arrangement is rotatable in housing
Method for determining spring pre-stress at spring-bearing-arrangement for balancing thermal conditioned position changes in motor car-axle drive, involves measuring spring force after arrangement is rotatable in housing
The method involves impacting a spring-bearing arrangement against spring force in an accelerated manner in an installation condition. The spring force is measured as an application value of spring pre-stress after the spring-bearing arrangement is freely rotatable in housing (2). The pre-stress is determined using a hydraulic pressure sensor (22) under consideration of a piston effective surface, where the hydraulic pressure sensor is provided in a hydraulic variable pressure impacted piston-cylinder unit in a tensioning device (14).
