Fig. 1 is the schematic plan of clutch compressing disc assembly according to an embodiment of the invention.Fig. 2 is the schematic perspective view of the assembly of clutch compressing disc shown in Fig. 1.The assembly of clutch compressing disc shown in Fig. 1 comprises front platen 1 and rear platen 2.Front platen 1 is by axially extended connecting bolt 6(and/or connecting pin) be connected to described rear platen 2.In the illustrated embodiment in which, four connecting bolts 6 are shown.But the present invention is not limited thereto, the quantity of connecting bolt 6 can be arranged as required, such as, it is two, three, five etc.
Front platen 1 is for transmitting power to reducer input shaft.Rear platen 2 is for receiving the power from engine output shaft, and it can rotate along driving sense of rotation R.In normal operating conditions, rear platen 2 drives front platen 1 to rotate along driving sense of rotation R, thus, power is passed to the input shaft of retarder from motor.Be less than the abnormal conditions of transmission input shaft rotating speed at engine output end rotating speed under, front platen 1 drives rear platen 2 to rotate along driving sense of rotation R, and now, the relatively rotation place relation between front platen 1 and rear platen 2 as shown in Figure 1.Now, the clockwise side contacts of circular hole 23 on the sidewall of connecting bolt 6 and rear platen 2.
As shown in Figure 1, between circular hole 23 hole on connecting bolt 6 and rear platen 2, there is gap, thus front platen 1 can be relatively rotated relative to rear platen 2 between the first relatively rotation place (normal operation position) and the second relatively rotation place (position shown in Fig. 1).
At described first relatively rotation place, the sidewall of connecting bolt 6 contacts with the counterclockwise side (namely against the side of sense of rotation R) of circular hole 23 on rear platen 2, and rear platen 2 drives front platen 1 to rotate along driving sense of rotation; At described second relatively rotation place, front platen 1 drives rear platen 2 to rotate along driving sense of rotation.Advantageously, the hole front platen 1 and/or rear platen 2 holding connecting bolt 6 is circular hole, thus guides the relative rotary motion of front platen 1 and rear platen 2 better, and the front platen 1 of maintenance and rear platen 2 is coaxial.It is pointed out that the differential seat angle between described first relatively rotation place and the second relatively rotation place is very little, such as, be less than 0.5 degree, 1 degree, 3 degree or 5 degree.Preferably, angle is less than 0.5 degree.
Fig. 3 is the schematic perspective view of the front platen of the assembly of clutch compressing disc shown in Fig. 1.Fig. 4 is the schematic plan of front platen shown in Fig. 3.Before diagram, platen 1 has the first backstop 11, first elastic bolster guide 12, circular hole 13 and the first receiving groove 14.Circular hole 13 and connecting bolt 6 closely cooperate.First receiving groove 14 provides holding space for holding Detecting element etc.
Fig. 5 is the schematic perspective view of the rear platen of the assembly of clutch compressing disc shown in Fig. 1.Fig. 6 is the schematic plan of rear platen shown in Fig. 5.After diagram, platen 2 has the second backstop 21, second elastic bolster guide 22, arcuate socket 23 and the second receiving groove 24.Arcuate socket 23 allows connecting bolt 6 to slide within it, thus allows front platen to rotate between described first relatively rotation place and the second relatively rotation place relative to rear platen.The two ends of arcuate socket are semicircle orifice, and radial both sides are that interior connection circular arc is connected circular arc with outer, and described interior connection circular arc is connected the center of circle of circular arc and the center superposition of rear platen with outer, thus guide the slip of connecting bolt 6 or alternative pin.Second receiving groove 24 provides holding space for holding Detecting element etc.

Pressure transducer 3 is used as detection device to detect the relatively rotation place of rear platen and described front platen, and sends testing signal.See Fig. 8, pressure transducer 3 is arranged between the first backstop 11 on front platen 1 and the second backstop 21 on rear platen 2.First backstop 11 and the second backstop 21 circumference spaced apart.In fig. 8, the first backstop 11 on front platen 1 is close on the right side of pressure transducer 3, passes on left sensor spring 4 and associates with the second backstop 21 on rear platen 2.When the spacing of the first backstop 11 and the second backstop 21 reduces, the decrement of sensor spring 4 increases, and the pressure that pressure transducer detects increases, and the relatively rotation place after representing between platen 2 and front platen 1 is close towards described first relatively rotation place.When the spacing of the first backstop 11 and the second backstop 21 increases, the decrement of sensor spring 4 reduces, and the pressure that pressure transducer detects reduces, and the relatively rotation place after representing between platen 2 and front platen 1 is close towards described second relatively rotation place.In the position that sensor spring 4 decrement is maximum, the relatively rotation place after representing between platen 2 and front platen 1 is in described first relatively rotation place.
Be understandable that, can change the first backstop 11 and the second backstop 21 position in the circumferential, now, in the position that sensor spring 4 decrement is maximum, the relatively rotation place after representing between platen 2 and front platen 1 is in described second relatively rotation place.In the case, at described first relatively rotation place, the pressure that described pressure transducer detects is minimum value; At described second relatively rotation place, the pressure that described pressure transducer detects is maximum value.This makes larger pressure representative need the abnormal conditions of monitoring: engine output end rotating speed is less than transmission input shaft rotating speed.
It is pointed out that sensor spring 4 also can be arranged between the side of pressure transducer 3 and the first backstop, now, the opposite side of pressure transducer 3 is against the second backstop.In an alternative embodiment, pressure transducer 3 is arranged between the first backstop 11 and the second backstop 21 with ralocatable mode, and two at pressure transducer are provided with sensor spring.
Range sensor can also be adopted to detect the circumferential relative position between described first backstop and described second backstop backstop, and send testing signal.Because angle is very little in relative rotation, thus determine that angle change is point-device with linear measure.
Advantageously, described pressure transducer or range sensor are wireless type pressure transducers.Thus be conducive to the transmission of testing signal, avoid wire harness and rotating member to interfere.
See Fig. 8, further with the first spring backstop 12 on front platen 1, further with the second spring backstop 22 on rear platen 2.Between described first spring spring backstop and described second spring backstop, be provided with limit spring 5 as elastic device, described elastic device applies elastic force F1 and F2, and described front platen and described rear platen are remained on described second relatively rotation place.Advantageously, limit spring 5 is pressurized helical spring, thus structure is simple, work is more reliable.Limit spring 5 can reduce the impact after when motor runs between platen 2 and front platen 1.In a preferred embodiment, described elastic device applies elastic force and described front platen and described rear platen is remained on described first relatively rotation place.
The present invention also provides a kind of vehicle, and described vehicle comprises clutch compressing disc assembly as above.
Advantageously, described vehicle comprises control unit further, described control unit receives the testing signal of described detection device, when the relatively rotation place of platen and described front platen departs from described first relatively rotation place in the rear, increases the fuel delivery to motor.Realized the supply of fuel oil by engine control system, thus reduce the impact because engine speed declines suddenly to related components and occupant.
Adopt clutch compressing disc assembly of the present invention, the relatively rotation place of front platen and rear platen can be detected, judge the phase difference of engine output end and transmission input shaft thus, determine that engine output end rotating speed is less than the situation of transmission input shaft rotating speed, thus corresponding measure can be taked in time, change this situation as early as possible.
