Abstract

The invention relates to a low-noise energy-saving test bed for the offline detection of 55KW-stage electric loading for an automobile gear-box and an operating method thereof. The test bed comprises a test bed main body, a motor box body, an electric transmission control system, a computer measuring-controlling system and an intensive oil supply hydraulic station, and is characterized in that a noise measuring device is arranged on the tested gear-box and a tray sliding table is arranged under the tested gear-box; and a gear shift device and a handle gear shift force operation measuring device are arranged on the right side of an operator who faces to the test bed. The test bed has the advantages of providing large torque up to 140Nm and meeting requirements on 30 to 100 percent of the factory detection of the loading of the gear-box with multi-specification variety types in the range of between 90 and 350Nm, reducing noise of a machine tool to be lower than 80dB through motor noise isolation and other noise reduction measurements, adjusting center distances and vertical dropping distances of input / output shafts to adapt to positioning and mounting of the gear-box with different variety specifications, adopting electric sealing power to feed back loading for energy conservation, and adopting an industrial control computer system and a measuring instrument to realize automatic control of a testing process.

Description

(1) Technical field: [0001] The invention belongs to an electric loading detection device of an automobile gearbox, in particular to a low-noise and energy-saving off-line detection 55KW electric loading test bench for an automobile gearbox and a working method thereof. (two) background technology: [0002] The low-noise and energy-saving off-line inspection of automobile gearboxes, the 55KW electric loading test bench can provide a high torque of up to 140Nm, which can meet the needs of 30~100% factory inspection of multi-specification and model gearboxes with rated torques ranging from 90 to 350Nm. And the noise of the machine tool body can be reduced to below 80dB. The test bench is an indispensable equipment for the off-line inspection of gearbox production, and the loading inspection test is carried out on the gearbox assembly one by one. The testing object of this test bench is the car manual transmission and so on. Carry out a driving test on the gearbox under loadi...
