Working principle of the present utility model:
On the one hand, for the technological scheme being provided with linking type marking scale, when stepping on dynamic clutch, the push-plate of clutch booster promotes linking type marking scale and moves right, if the distance moved right is larger just show that the degree of wear of clutch disk is larger, when clutch disk wearing and tearing are excessive, linking type marking scale can trigger dress sensor probe thereon and produces signal and export signal lamp or the instrument panel of operator cabin to, can point out replacing clutch disk immediately.By sensor probe, this technological scheme also senses that clutch booster promotes the stroke of clutch friction plate clutch position, just by controlling the stroke of reading to friction plate clutch position of this signal and feed back simultaneously after stroke being transferred to AMT system with analog amount or CAN signal mode.
In addition, this technological scheme can also realize the clutch number of times of clutch in automatic fault diagnosis and omnidistance record car load running process and state and be supplied to Tachographs in real time.Wherein, automatic fault diagnosis comprises and carries out automatic decision to clutch mechanism structure failure and carry out self-inspection to sensor fault.Working principle about mechanical failure self-inspection is: in clutch pedal bottom, clutch separation switch is housed, its Main Function closes to making clutch separation switch during limit position when stepping on dynamic clutch pedal, illustrates that now clutch has been in complete separated state.Driver is when carrying out clutch separation, when stepping on dynamic clutch pedal to touching clutch separation switch during limit position, meanwhile clutch separation switching signal also can send to ECU immediately, if now stroke signal is not transferred to ECU with analog amount or CAN signal mode or is transferred to the stroke signal value of ECU too small by sensor, can judge that a whole set of mechanical structure of this clutch there occurs mechanical failure.Working principle about sensor self-inspection is: when beyond when the peak set or minimum, the signal value of sensor can judge that sensor there occurs fault.In addition, when stepping on dynamic clutch pedal and namely not touching clutch separation switch to limit position, the stroke signal value of sensor but reaches the stroke signal value that could export when only having clutch to be separated completely, now also can judge that sensor there occurs fault.
Surveyed and statistic data result according to moving vehicle shows, frequent traveling is at the vehicle of urban area buty shifting, the wearing and tearing of its clutch push-plate are all very serious, cause the reason of this phenomenon, general is all due to the operation of driver's cruelty or unreasonable operation, cause clutch not being separated completely or not engaging the operation just carrying out gear shift or open out completely, cause clutch disk excessive wear.This technological scheme is by clutch position during sensor record gear shift and send it to Tachographs, can educate in time, remind and correct the improper operation behavior of driver; Also can be recorded the separation number of times of clutch in whole driving conditions simultaneously by sensor, thus remind driver to carry out maintaining in time to the associated structural component of clutch in good time.
On the other hand, for the technological scheme being provided with non-linking type marking scale, when stepping on dynamic clutch, the push-plate of clutch booster promotes non-linking type marking scale and moves right, if the distance moved right is larger just show that the degree of wear of clutch disk is larger, when clutch disk wearing and tearing are excessive, non-linking type marking scale can trigger dress sensor probe thereon and produces signal and export signal lamp or the instrument panel of operator cabin to, can point out replacing clutch disk immediately.
