Abstract
Abstract In the laboratories of Czech Technical University in Prague a new inertia test stand was designed and realised. Its main purpose is to test the behavior and endurance of the internal shift mechanisms of passenger car gearboxes. In this paper we present further usage of the test stand, which consists of measurement of gearbox losses. The gearbox on the inertia test stand cannot be loaded; therefore the target is the measurement of losses resulting mainly from splash lubrication and some additional gearbox friction (e.g. friction in shaft sealing, bearing losses). The most typical passenger car mechanical five speed gearbox for transversal position of the drivetrain was chosen for this experiment.
