Abstract
The invention provides an overrunning clutch reliability test method and a test bed, and belongs to the test method of a clutch. The method comprises the following steps of: constructing a speed changing box assembly performance test bed, wherein a power source and loading equipment adopt alternating-current variable frequency motors, and the rotating speed and the rotating torque of each of the alternating-current variable frequency motors can be regulated; detecting the transmission efficiency of a speed changing box assembly; and drawing a relation curve between the transmission efficiency and the output rotating speed of the speed changing box according to a test result, wherein a phase change point in the curve represents working states of separation and combination of the overrunning clutch. Seven components of the special test bed, namely a power alternating-current motor, an input rotating torque and rotating speed sensor, a transmission shaft, a speed changing box torque converter assembly, an output rotating torque and rotating speed sensor, a six-gear transmission box and a loading alternating-current motor are connected in sequence. The overrunning clutch reliability test method and the test bed have the advantages of truly representing the working condition of the overrunning clutch and facilitating the speed changing box performance test and the overrunning clutch reliability index test.
Description
Technical field
The present invention relates to a kind of test method of clutch coupling, particularly a kind of overrunning clutch reliability test method and test-bed.
Background technology
Overrunning clutch is a vitals of two hydrotransmitter assemblies, and it can regulate twin-turbine torque converter I and II turbine working condition automatically according to the shovel loader working condition requirement.Along with the market demand, the shovel loader tonnage increases gradually, and to the also raising thereupon of reliability requirement of overrunning clutch, so the reliability performance of overrunning clutch is also as one of important performance assessment criteria of transmission assembly combination property.
Overrunning clutch producer generally all is equipped with special-purpose overrunning clutch Performance And Reliability testing table at present, but when overrunning clutch and transmission assembly co-operation, its working condition influences bigger with fluid torque-converter stressing conditions difference, the load condition that can not truly reflect overrunning clutch, the fail-test of overrunning clutch is finished on wheel box performance test basis.
Summary of the invention
The objective of the invention is to provide a kind of: the overrunning clutch reliability test method and the test-bed that can truly reflect the load condition of overrunning clutch.
The object of the present invention is achieved like this: at first build the transmission assembly testing stand for performance test, power source and loading equipemtn all adopt ac variable-frequency electric motor, the rotating speed of ac variable-frequency electric motor and torque can be regulated, detect the transmission efficiency of transmission assembly, test result is depicted as the relation curve of transmission efficiency and wheel box output speed, and the transformation temperature in the curve map reflects that overrunning clutch separates and the duty of combination.
The special-purpose test-bed of realizing test method of the present invention includes: power alternating current generator (1), input torque speed probe (2), transmission shaft (3), wheel box torque converter assemblage (4), output torque rotary speed sensor (5), six grades of transmission cases (6) and loading alternating current generator (7), power alternating current generator (1), input torque speed probe (2), transmission shaft (3), wheel box torque converter assemblage (4), output torque rotary speed sensor (5), six grades of transmission cases (6) and loading alternating current generator (7) are linked in sequence.
Beneficial effect, owing to adopted such scheme, this test method is on the basis that records transmission assembly transmission efficiency and wheel box output speed relation curve η=f (n), record transmission assembly fluid torque-converter I and II turbine works independently and cooperative transformation temperature, i.e. transmission assembly output speed, output torque at this moment; Make near the interval periodic duty of transmission assembly transformation temperature, to overrunning clutch carry out " engage-＞separate-＞engage " the periodic duty process, can truly reflect the load condition of overrunning clutch to have reached purpose of the present invention.
Advantage: for the working condition of true reflection overrunning clutch, take into account the test of overrunning clutch reliability index when making things convenient for the transmission assembly performance test, the invention provides a kind of overrunning clutch reliability test method and test-bed based on transmission assembly.
