Power takeoff rack test device and test method thereof

Abstract

The invention discloses a power takeoff rack test device and a test method thereof, and belongs to the technical field of transmission test. The driving motor is connected with the input end of the first-gear speed increasing box, the output end of the first-gear speed increasing box is connected with the input end of the torque rotating speed sensor, the output end of the torque rotating speed sensor is connected with the power takeoff rack service life testing mechanism, and the power takeoff rack service life testing mechanism is connected with the dynamometer. The clutch gear shifting mechanism is connected with the tested transmission, and the power takeoff gear shifting mechanism is connected with the tested transmission. The tested transmission is checked; the power takeoff rack service life test mechanism is assembled, connected and tested, and a test result is obtained; and the power takeoff rack test device is assembled, connected and tested, and a test result is obtained. The special function under specific conditions can be achieved, and application in the fields of special vehicles, agricultural vehicles and the like is wider and wider; and the power takeoff gear engaging and disengaging test and service life test requirements of a special automobile power takeoff can be met, and then the blank in the field is filled up.

Description

technical field [0001] The invention relates to a power take-off bench test device and a test method thereof, belonging to the technical field of transmission tests. Background technique [0002] Mechanical products are widely used in people's life and production. Like all products, mechanical products have a limited service life. And a lot of practical experience shows that the failure of most mechanical products is caused by the failure of a certain part or some parts. [0003] The power take-off is mainly equipped with shafts, gear teeth and housings, etc. Therefore, it is very necessary to perform bench fatigue test assessment on the above components to ensure the service life of the power take-off. [0004] At present, some models of T18R transmissions have been equipped with power take-offs and occupy a certain amount of the market. Although the new models T19R and T25R also have plans to be equipped with power take-offs, the reliability test assessment based on the b...
