Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to a test device and a test method for the transmission efficiency of a plug-in hybrid transmission. Background technique [0002] Today, with increasingly stringent fuel regulations, major automakers are trying their best to seek and break through high-efficiency powertrains, especially deep hybrid models have gradually become one of the trends. Among them, the measurement of shafting torque is an indispensable and important mechanical performance test item in machinery industry, especially shipbuilding, automobile, aircraft, lifting and military enterprises. It not only provides accurate theoretical data for industrial design, but also directly provides The inspection makes an evaluation of the technical performance. [0003] The current torque testing methods are mainly divided into two types, one is the frequency measurement method, and the other is the strain ...
