Researchers at Penza State University (PSU) have developed and patented a test bench for mechanical and continuously variable transmissions (CVT). The invention is ready for implementation in automobile production.
According to Alexandra Generalova, Associate Professor of the Department of "Transport Machines", the CVT test bench consists of a frame with a traction electric motor, a loading electric motor connected to the transmission output shaft. The design also includes a control unit that smoothly changes the load and displays the readings on the screen.
Testing know-how in the automotive industry usually takes place on open proving grounds, which requires additional funding. It is expected that the test bench created at PSU will reduce the cost of testing CVTs, as it allows testing in laboratories and at enterprises. It is possible to test gearboxes for both Russian and foreign cars, the university summarized.
