Problems solved by technology

In recent years, there are many devices for measuring the output power of automobile chassis without disassembly, such as hydraulic dynamometer, electric dynamometer and eddy current dynamometer. The technologies are relatively mature, but the equipment for measuring the power of automobile engine without disassembly is relatively rare. Many disassemble the engine from the car to obtain its power through the bench method, which is more troublesome

Description

technical field [0001] The invention relates to a measuring device for a transmission system of an automobile, in particular to a measuring device and a measuring method for transmission efficiency of an automobile transmission system without disassembly. Background technique [0002] There are various forms of automobile transmission system, and the mechanical type is more extensive. With the continuous advancement of technology, the hydraulic transmission system is becoming more and more popular. In order to reduce the fuel consumption of automobiles, one of the means is to improve the transmission efficiency of the transmission system, reduce the energy consumption of the automobile itself, and make the maximum use of engine power. The transmission efficiency of the mechanical transmission system is about 90%, which is the highest among all transmission methods. The same car has slight ups and downs with different assembly, use, and maintenance. It is difficult to accura...
