Abstract

The invention relates to an online detection electric-loading test bed for a car hand-gear gearbox and an operating method thereof. The test bed comprises a test bed main body and a motor case body, an electric driving control system, a computer measurement and control system, and an oil supply system, and is characterized in that a clutch unit is connected behind a torque revolution speed transducer of the test bed, a tray sliding table is arranged under a tested gearbox, and the tested gearbox has a structure with two output shafts. The test bed and the operating method thereof have the following advantages: conductively closed power feedback loading is adopted for saving energy sources; an input shaft driving motor and an output shaft driving motor of the tested gearbox on the test bed are the power input and the power output of each other; and under the state of seamless smooth conversion electric driving and regenerative power generation, the four-quadrant work is realized; a structure that motors are separated from a machine tool main body is adopted, and the motors are arranged in an independent case body; the test bed is applicable to the tests of various models of hand-operated and automatic gearboxes; an industrial control computer system and a measurement and control instrument are adopted to realize the automatic control for test procedures; the test bed has perfect interlocking protection function; and a quantitative oil feeding and discharging system is adopted.

Description

(1) Technical field: [0001] The invention belongs to an electric load detection device for a car gearbox, in particular to an electric load test bench for on-line detection of a car manual gearbox and a working method thereof. (2) Technical background: [0002] The electric loading test bench for on-line inspection of manual transmission of cars is an indispensable equipment for the off-line inspection of gearbox products in the manufacturer. It performs loading inspection tests on the gearbox assemblies one by one. The testing object of this test bench is the car manual transmission and so on. Carry out a drive test on the gearbox under loading conditions, that is, to detect the torque, transmission ratio, noise or noise and smoothness of shifting gears transmitted by each gear of the gearbox at a given speed in the test specification, as well as the gear drop under the specified torque, Out of gear or out of gear detection, so as to judge the factory qualification of the ...
