Continuously variable transmissions, CVT's, are used where the stepless change of torque and/or speed is necessary. While this kind of transmission was first used only in general industrial drive assemblies, nowadays almost all car producers worldwide are providing passenger cars preferably with embracing-CVT's. Through the employment of CVT's, benefits like increased driving comfort, reduced noise emission and fuel consumption can be obtained in comparison to conventional manual or automatic transmissions. Considering the demands of costs, lightweight and performance the comparative testing of load capacity of the available CVT-systems on the market, built with embracing organs, gives the transmission developers helpful information. In continuous work a test rig based on the principle of power circulation was developed at the FZG in order to test the load capacity of continuously variable embracing-transmissions. The mechanic and hydraulic function of the test rig, the construction of three variator systems (embracing organs, sheaves) and the test method are described. The results of constant load tests in three different working points of the variator by variation of the load are discussed. In this connection a differentiation of the damages, - breakage of the chains/belt and scuffing on the sheaves -, is shown. Basing on the test results of constant load tests woehler diagrams and the results of multiple load tests of one embracing organ are presented. The results are part of an extensive research project realized at the FZG in order of the Forschungsvereinigung Antriebstechnik e. V. (FVA) [1] and a valuable basis for further development of variator systems.
