Air spring bag testing method for e.g. commercial vehicle, involves filling air spring bag with air upto specific pressure through air connection, and determining pressure drop in bag within preset time period

摘要

The method involves filling an air spring bag (1) with air upto a specific pressure through an air connection (2). Pressure drop in the bag within a preset time period is determined, and the air connection to the bag is locked by a stop-valve (3) during the time period Air pressure of the bag is measured by a pressure sensor (4). A measuring signal of the pressure sensor is guided to a control unit. An independent claim is also included for a device for performing an air spring bag testing method, comprising a control unit.
