Embodiment
Describe embodiment of the present utility model below in detail, described embodiment's example is shown in the drawings, and wherein same or similar label represents same or similar element or has the element of identical or similar functions from start to finish.Be exemplary below by the embodiment who is described with reference to the drawings, only for explaining the utility model, and can not be interpreted as restriction of the present utility model.
As shown in Fig. 1, Fig. 5, Fig. 7 and Fig. 9, clutch generally includes clutch housing 2, disengaging yoke 5, release sleeve and release bearing assembly 6, diaphragm spring 7, clutch cover 8, platen 9, driven disc, transmission input shaft 12 and flywheel 13.The working principle of clutch is: driver normally travels while not stepping on clutch pedal, diaphragm spring 7 utilizes the elasticity of self by platen 9, the friction plate of driven disc 10 to be pressed on flywheel 13, because motor rotates by bent axle flywheel driven 13, therefore, friction plate 10 on driven disc can be delivered to the torsion of flywheel 13 on driven disc by frictional force, driven disc just can drive transmission input shaft 12 to rotate by spline, thus by the transmission of power of motor to speed changer; When driver steps on after clutch pedal, clutch pedal drives disengaging yoke 5 to move by mechanical drag-line or hydraulic mechanism, disengaging yoke 5 promotes or pulls release sleeve and release bearing assembly 6, release sleeve and release bearing assembly 6 promote or pull diaphragm spring 7, make platen 9 unclamp the friction plate to driven disc, the friction plate 10 of driven disc just separates with flywheel 13, although separating rear flywheel 13 still rotates, but due to the friction plate 10 of driven disc with divided flywheel from, therefore flywheel 13 will can not drive driven disc rotation, and engine power just cannot be delivered to speed changer.
Based on above-mentioned working principle, as shown in Fig. 1 to 10, clutch control device of the present utility model comprises the inductor 11 that puts in place that weares and teares, controller 3, alarm 14 and Engine ECU 1, wherein, these wearing and tearing put inductor 11 in place for exporting the signal that puts in place that weares and teares, these wearing and tearing inductor 11 that puts in place is embedded in the inside of friction plate 10 in advance, and and distance between the outer surface of friction plate 10 equals the wear allowance of setting, it is for friction plate 10 is installed on to the rivet on follower that this distance should be less than this rivet of rivet head 15() and the outer surface of friction plate 10 between distance, to avoid rivet head 15 to contact with flywheel 13, result in greater loss, wherein, the outer surface of friction plate 10 is the surface relative with flywheel 13 of friction plate 10, at this, because the friction plate of driven disc 10 allows to be worn under normal circumstances, friction plate only just there will be fault in the time may wear to a certain degree, lose function, therefore need to set the degree of wear of wear allowance sign friction plate, corresponding the purpose of this utility model, there are ablation, wearing and tearing in the corresponding friction plate of this wear allowance, but position when also thoroughly not burning or not may wear to the limit.This controller 3 receives the wearing and tearing signal that puts in place for the signal input port that puts in place by the wearing and tearing that arrange, and in the time receiving wearing and tearing and put signal in place by the alarm signal output ends mouth output alarm signal that arranges with change signal by the state signal output port output state arranging.The Enable Pin of alarm 14 is electrically connected with alarm signal output ends mouth, to report to the police in the time receiving described alarm signal, remind driver's clutch to start fault, Please drive carefully and go repairing in time, and this alarm 14 is for example warning light, buzzer or the combination of the two.The state signal input port of this Engine ECU 1 is electrically connected with the state signal output port of controller, make Engine ECU 1 know that friction plate may wear to wear allowance, on this basis, those skilled in the art can Engine ECU 1 start limp-home function receiving after condition change signal, to reduce engine power output, vehicle can be repaired by low speed driving to maintenance station.Above controller 3 can be installed in clutch housing 2, also can be installed on any position of the vehicle outside clutch housing 2.
In order to form Redundancy Design, clutch control device of the present utility model can also comprise at least two wearing and tearing inductor 11 that puts in place, at least two wearing and tearing inductor 11 that puts in place can upwards be uniformly distributed around the week of transmission input shaft 12, as long as it is output alarm signal and condition change signal that controller 3 receives by wearing and tearing wearing and tearing that inductor 11 the exports signal that puts in place that puts in place, lost efficacy and cause clutch control device to lose efficacy because of the inductor that puts in place of part wearing and tearing wherein avoiding, for controller 3, each wearing and tearing signal that puts in place is the relation of phase "or", adopt under normal circumstances two Redundancy Design.
Embodiment 1:
As illustrated in fig. 1 and 2, above-mentioned wearing and tearing put inductor 11 in place for being surrounded by the wire of insulated hull, wire is embedded in friction plate 10 in advance with the orientation parallel with the outer surface of friction plate 10, wearing and tearing put in place the conductor of distance corresponding lead between the outer surface of inductor 11 and friction plate 10 and the distance between the outer surface of friction plate 10, wire transfers to controller 3 via a collecting ring 4 by the wearing and tearing signal that puts in place, particularly, the interior ring of this collecting ring 4 with limit its in relative rotation mode be installed on transmission input shaft 12, be that collecting ring 4 is followed transmission input shaft 12 and rotated together, the interior ring of collecting ring 4 is electrically connected with wire, the outer shroud of collecting ring exports the wearing and tearing signal that puts in place to controller 3, at this, the outer shroud of collecting ring 4 can be fixedly mounted in clutch housing 2.In the time of friction plate 10 normal work, as shown in Figure 3, do not form earth-return; In the time that friction plate 10 wears up to the wear allowance of setting, as shown in Figure 4, the insulated hull of wire is worn through, and the conductor of wire inside contacts with flywheel 13, is connected with the ground wire of motor by flywheel 13, forms earth-return, and then produces the signal that puts in place that weares and teares.
Because friction plate 10 needs 200-300 ℃ of high temperature man-hour in hot-forming adding, and friction plate also can produce high temperature at work, is greater than 400 ℃ of high temperature resistant wires so wire 11 can be selected, for example, be AF-400 type high temperature resistant wire.For example, if the wear allowance of setting is 2.1mm, making the distance between the outer surface of conductor in wire and friction plate 10 is 2.1mm substantially, if ignore the thickness of insulated hull, making the distance between the outer surface of wire and friction plate 10 is 2.1mm substantially, " substantially " herein refers to allow to exist detect error, and the error allowing can be selected according to the control accuracy of the clutch control device of design.
