US Patent 8635904 Torque-application test stand for transmissions

A torque-application test stand in which a belt drive or chain drive having two fixed belt stations and having one belt station which is movable in a linear manner between the two fixed belt stations is provided. A telescopic universal-joint propeller shaft for length compensation is arranged between the belt station which is movable in the linear manner and a bearing support for a test object. The belt station which is movable in the linear manner is moved during testing, thus producing a superimposed rotary motion of the universal-joint propeller shaft connected to the test object.
