The content of the invention
The purpose of the present invention is in view of the shortcomings of the prior art, to propose a kind of transmission selector fork strength test system, Solving transmission selector fork in the prior art, caused deformation lacks the test hand that can quantify in the course of the work The problem of section.
The technical proposal of the invention is realized in this way:
A kind of transmission selector fork strength test system, it is characterised in that:System includes execution unit, data acquisition list Member, working condition analogue unit and data processing unit, the execution unit are a forcing press, and the data acquisition unit is Displacement transducer and pressure sensor, the working condition analogue unit by base, fixed guide pole, quick change press head, adjusting sleeve, Pressing plate, shift fork axle and guide sleeve are formed, and data processing unit is made up of microcomputer and data processor, and during test, speed changer changes Keep off shift fork to be arranged in shift fork axle, pressing plate is installed on two prong faces of transmission selector fork, pressure is housed on forcing press Sensor, head are connected with pressure sensor, and the prong face of transmission selector fork is vertical with test pressure, and forcing press drives Head applies pressure at right angle by pressing plate, and pressure caused by test passes through pressure sensor and displacement sensing with displacement information Device is connected with the data processing unit, and related data is handled by data processor, and the output data curve in microcomputer And test result.
Further, the forcing press is screw rod leading screw forcing press, and the screw rod leading screw of forcing press drives head to pass through pressure Plate applies pressure at right angle.
Further, head front end contact portion is designed as the structure of " sphere ", and head front end is inlayed high hard Spend ball.
Further, the working condition analogue unit can be by changing different quick change press heads, shift fork axle and guiding Set, which is realized, tests all kind transmission selector fork intensity.
Further, the pressure sensor uses bidirection press sensor.
Further, institute's displacement sensors use high-precision angular displacement sensor.
According to above technical scheme, during test, transmission selector fork is arranged in shift fork axle, in transmission selector fork Two prong faces on pressing plate is installed, transmission selector fork face is vertical with test pressure, screw rod leading screw drive head pass through Pressing plate applies pressure at right angle.Pressure is delivered in pressure sensor by head caused by test, and displacement is passed by screw rod leading screw It is delivered in displacement transducer.Pressure sensor and displacement transducer are connected with the data processing unit, and data are by data Manage program processing, by result in microcomputer output data curve and test result, by control system according to pressure signal and displacement Signal judges whether the intensity of transmission selector fork meets standard.
Head front end of the present invention contact portion is designed as the structure of " sphere ", makes to act on shift fork prong face Power all the time perpendicular to prong face;The structure of high hardness material is inlayed in head front end, reduces because head contacts point deformation And caused error, measuring accuracy are high, distinguishable pressure precision is 0.01KN, and distinguishable displacement accuracy is 0.01mm.
Present invention survey is applied widely, and current all commercializations can be realized by changing quick change press head, shift fork axle and guide sleeve The test of car transmission selector fork;The working condition analogue unit of the present invention simulates transmission selector fork real work The state of journey, the performance of acquired test data energy actual response shift fork.
