Described test-bed both sides are provided with the support platform of protrusion, place active drive motor and driven drive motor on the support platform.
Described pressure transducer is ring-type.
The utility model utilizes shift fork, and rotatablely moving of motor is converted into rectilinear motion, promotes pressure sensor connecting piece and then promotes circular pressure sensor and release bearing, thereby realize separation and the bonding operation of clutch coupling.The worm type of reduction gearing that links to each other with release bearing drive motor output terminal has auto-lock function, thereby mechanism is unlikely to backward rotation when disconnection fault occurring in system.
Clutch friction pad wear self-adaptation part is equipped with the circular pressure sensor behind release bearing, engage snap-in force before and after detecting wearing and tearing
fChange, according to formula
Can obtain clutch coupling carry-over moment information, thereby provide Data support to electric-control system, make it according to different operating modes, adjust joint opportunity and speed.
When clutch coupling need to engage, the circular pressure sensor is according to eliminating idle motion, proportion distribution variation synchronous, synchronously ending phase in the engaging process of snap-in force signal intensity monitoring line traffic control clutch friction plate after wearing and tearing, the drive motor of release bearing is under the control of controller, control algolithm requirement according to each zygophase, with certain rotating speed rule rotation, make release bearing under the cooperation of shift fork, spacing pallet etc. along rectilinear motion, thereby the motion of control release bearing makes the driving and driven part of clutch coupling engage according to optimum rule.When clutch coupling will separate, the reverse rotation of release bearing drive motor, release bearing is also done motion in the other direction, makes clutch separation.
Superior effect of the present utility model is:
1) circular pressure sensor of the present utility model carries out real-time status detection and record, in order to the engaging process of friction disc wear is analyzed and improved, the working environment of real simulation clutch coupling;
2) corresponding component of this testing table all can rotate according to computer control signal, has simulated better the working condition of clutch coupling in the real vehicle;
3) this testing table has adopted half scheme in kind: clutch part adopts in kind, be equipped with corresponding sensor, car load partly adopts computer simulation model, can detect the abrasion condition of clutch coupling and adjust clutch coupling to engage opportunity, speed, can understand again the clutch coupling operating mode to the impact of Full Vehicle System.
