The reliability testing device has the advantages that reliability index appraisal of the gear clutch can be conducted after the performance testing of speed-changing box is finished, a scaffold does not need to be set to appraise the gear clutch, and the load of the gear clutch is closest to the actual condition.

Description

Wheel box gear clutch coupling reliability test
Technical field
The utility model relates to a kind of clutch test device, particularly a kind of wheel box gear clutch coupling reliability combined test apparatus.
Background technology
Wet clutch is widely used in the homemade Powershift transmission at present, realizes gear shift, the commutation of wheel box.Wherein the reliability of the groundwork element of clutch coupling such as friction element and elastic recoil element is most important, directly has influence on the functional reliability of wheel box.The special clutch testing table can be accomplished the examination to the clutch coupling Performance And Reliability now, but present wheel box such as fixed axle gearbox, use a plurality of clutch couplinges, its function, operating mode are incomplete same, reliability testing to clutch coupling, can not consider simultaneously with the matching state of wheel box hydraulic pressure, mechanical system and test, so the reliability testing of clutch coupling is preferably based on transmission assembly and finishes.
The utility model content
The purpose of this utility model is will provide a kind of can consider the wheel box gear clutch coupling reliability test of testing with the matching state of wheel box hydraulic pressure, mechanical system simultaneously.
The technical scheme that its technical matters that solves the utility model adopts is: this test unit comprises interchange loading motor (1), input torque speed probe (2), torque converter transmission assembly (3), output torque rotary speed sensor (4), six grades of many grades of casees (5), exchange loading motor (6) and automatically controlled shift control valve (7), exchange loading motor (1), input torque speed probe (2), torque converter transmission assembly (3), automatically controlled shift control valve (7), output torque rotary speed sensor (4), six grades of many grades of casees (5) with exchange loading motor (6) and be linked in sequence, output torque rotary speed sensor (4) has been linked in sequence in the side of automatically controlled shift control valve (7), six grades of many grades of casees (5) with exchange loading motor (6).
Beneficial effect, owing to adopted such scheme, this test unit is according to the operating mode of the different gears of wheel box, utilize loading motor to simulate the operating load of different gears, wheel box periodic duty between different gears, gear shift cycling, utilize virtual instrument as Software Development Platform, with the gear switch of the automatically controlled shift control valve of motor pulses control wheel box, it is arranged in data acquisition and electric machine control system.In the gearbox gear-shift process, the automatically controlled shift control valve control signal of the control signal of motor and wheel box same frequency, same-phase, realization Electric Machine Control and gear shift are carried out simultaneously.Its course of work is that wheel box is when gear shift, by regulating the pulse signal of control motor, excitation gearbox gear-shift, realization gear shift and Electric Machine Control synchronous operation.When the wheel box gear switch, the gear clutch coupling is finished the action that engages or separate, and can consider simultaneously with the matching state of wheel box hydraulic pressure, mechanical system and test, and has reached the purpose of this utility model.
Advantage: can carry out the examination of gear clutch coupling reliability index after finishing the wheel box performance test, not need to set up separately stand examination gear clutch coupling, gear clutch coupling load is near truth.
Description of drawings
Fig. 1: wheel box gear clutch coupling fail-test arrangenent diagram.
Among the figure, 1, exchange loading motor; 2, input torque speed probe; 3, torque converter transmission assembly; 4, output torque rotary speed sensor; 5, six grades of many grades of casees; 6, exchange loading motor; 7, automatically controlled shift control valve.
Embodiment
Embodiment 1: this test unit comprises interchange loading motor 1, input torque speed probe 2, torque converter transmission assembly 3, output torque rotary speed sensor 4, six grades of many grades of casees 5, exchange loading motor 6 and automatically controlled shift control valve 7, exchange loading motor 1, input torque speed probe 2, torque converter transmission assembly 3, automatically controlled shift control valve 7, output torque rotary speed sensor 4, six grades of many grades of casees 5 with exchange loading motor 6 and be linked in sequence, output torque rotary speed sensor 4 has been linked in sequence in the side of automatically controlled shift control valve 7, six grades of many grades of casees 5 with exchange loading motor 6.
Method of work is as follows: be operated in the I shelves in the 0-A section, the A-B section is operated in the II shelves, and A and B point are respectively shift points.Wheel box begins operating in the I shelves, and along with load is elevated to M1 by 0, the wheel box output speed drops to n1 ' by n1, when load reduces gradually until zero load, the wheel box output speed rises to n1, changes to the II shelves at the A point, gearbox speed is elevated to rotation speed n 2, subsequently A-B change procedure 0-A as described above.
The control valve control signal of wheel box and loading motor loading spectrum signal are realized synchro control by measurement and control program, so wheel box the A point finish the I shelves->the II shelves, the B point finish the II shelves->the I shelves, wheel box always works in separately in the gear operating loading scope.
