Transmission efficiency is one of the main limiting factors on metal belt CVT large-scale assembly car. Metal belt CVT transmission efficiency has been invested in this paper, and, test-bed has been established by L13A3 engine, MB-CVT, brake, input sensor, output sensor, coupling and half shaft. Efficiency test results show that, with the decrease of transmission ratio, CVT efficiency first increases and then decreases. The range of efficiency is nearly 45%-89% in increases part (i>1), the range of efficiency is nearly 85%-89% in decrease part (i<1), the efficiency reaches the highest when transmission ratio is 1. The conclusions are in consistent with others conclusion, whereby demonstrating that the established transmission efficiency test-bed is rational and that the experiment results are reliable.
