In this embodiment, grooves are formed on one side of four lugs uniformly distributed around the middle pressure plate 12, and the adjusting block 35 is fastened at the grooves by screws. In particular, the adjustment block 35 is secured to the intermediate platen 12 by an adjustment block washer 36 and an adjustment block set screw 37. The main pressure plate and the middle pressure plate can obtain equal free gaps in the clutch separation process through the adjusting block, meanwhile, the transmission plate clamping plate is utilized to protect the transmission plate, and abrasion and deformation caused by frequent contact between the adjusting block and the transmission plate are avoided.
The working process of the invention is as follows:
in operation, the self-adjusting clutch special for the AMT automobile is in a normally combined torque transmission state, and engine torque is transmitted to an input shaft of a gearbox through the clutch;
in the separation process, the separation finger end of the diaphragm spring 2 is pushed to the flywheel direction along the axis, the large end of the disc area of the diaphragm spring 2 releases the pressing force to the adjusting ring 13 and the main pressure plate 9, the adjusting ring 13 and the main pressure plate 9 are unloaded, and the main pressure plate 9 moves to the gearbox direction along the axis under the action of the resilience force of four groups of driving plates 28 connected to four lugs of the cover 1 and the main pressure plate 9, for example:
assuming that the backward movement amount of the main pressing plate 9 is 1, the inner driven plate 39 moves along with the backward movement, and meanwhile, the middle pressing plate 12 also moves towards the direction of the gearbox under the resilience action of four groups of transmission plates 28 connected to four lugs of the connecting ring 11 and the middle pressing plate, and because four adjusting blocks 35 respectively fixed at four grooves uniformly distributed around the middle pressing plate 12 abut against the middle positions of corresponding transmission plate clamping plates 29, the backward movement distance of the middle pressing plate 12 is 1/2 of that of the main pressing plate 9, so that the clearance = 1-1/2 = 1/2 generated between the main pressing plate 9 and the middle pressing plate 12 is always equal to the free clearance obtained by the inner driven plate 39 and the outer driven plate 38. At this time, the outer driven disk 38 is disengaged from the engine flywheel surface as it moves rearward, and does not transmit engine power, completing the complete decoupling function.
During the coupling process, the main platen 9 is moved along the axis in the direction of the engine flywheel, followed by the inner driven disk 39, the intermediate platen 12, and the outer driven disk 39 in the direction of the engine flywheel until the coupling is completed. When no wear occurs in the friction plates of the outer driven plate 38 and the inner driven plate 39 during torque transmission, the wear self-adjusting compensation mechanism does not make compensation adjustment. When the friction plates of the outer driven plate 38 and the inner driven plate 39 are worn during the combined torque transmission process, the main pressure plate 9 and the intermediate pressure plate 12 move along the axis towards the flywheel surface, and the moving distance is the total wear thickness of the friction plates.
Because the front end of the elbow of the pressing piece 24 fixed on the main pressing plate 9 is always pressed on the head of the abrasion collection hook 6, the distance between the abrasion collection hook 6 and the flywheel surface is a fixed value, and when the pressing piece 24 moves along the axis along the main pressing plate 9 to the flywheel surface, the rear end of the elbow of the pressing piece 24 and the arc inclined surface at the upper end of the arc toothed piece 26 generate a gap. When the clutch is separated, the large end of the diaphragm spring 2 releases the pressing force applied to the adjusting ring 13 and the main pressure plate 9, the adjusting ring 13 and the arc-shaped tooth piece 26 rotate slightly clockwise by an angle towards the flywheel surface along the axial direction relative to the main pressure plate 9 under the action of the tension force of the large tension spring 21 and the small tension spring, the teeth of the tooth block 10 which is pressed and embedded on the rear end surface of the main pressure plate 9 by a plurality of small teeth at the lower end of the arc-shaped tooth piece 26 move relatively by a tooth pitch and then are meshed, namely, the gap between the rear end of the elbow of the pressing piece 24 and the arc-shaped inclined surface at the upper end of the arc-shaped tooth piece 26 is eliminated, and one-time compensation is completed. The diaphragm spring 2 is restored to the initial position when the clutch is re-engaged, and wear adjustment compensation is always achieved during the dynamic process from when the clutch is disengaged to when it is engaged again.
In summary, the invention has the following beneficial effects:
1. the invention can ensure that the working position of the diaphragm spring 2 and the distance between the separating finger end and the working surface of the flywheel are kept unchanged, the axial dimension is not increased, and the working position of the diaphragm spring 2 and the distance between the separating finger end and the working surface of the flywheel are increased along with the abrasion of the friction plate after the friction plate of the common push clutch is abraded, and the axial dimension is increased.
2. The invention can keep the diaphragm spring 2 at the initial installation position in the whole use process, thereby ensuring that the working pressing force of the clutch is not changed, solving the difficulty of pneumatic control of the heavy AMT clutch and ensuring the control precision of the clutch position and the stability of the clutch transmission torque.
3. The diaphragm spring 2 in the invention keeps the initial installation position in the whole service life, namely the working pressing force of the clutch is not changed after the friction plate is worn, so the thickness design of the friction plate can be increased, the service life is prolonged, and the service life can reach more than three times of that of a common clutch.
4. According to the invention, the diaphragm spring 2 maintains the initial installation position in the whole service life, namely, the clutch working pressing force is not changed after the friction plate is worn, so that the separating force is not changed, and compared with the normal diaphragm spring clutch, the separating force needs to be increased, so that the clutch control mechanism is relatively small in stress and easy to ensure rigidity.
5. The automatic wear adjusting mechanism is simple and reliable in structure, few in added parts and convenient to control cost;
6. the double-pressure-plate clutch has the advantages that the double-pressure-plate clutch absorbs working heat at the same time, the heat dissipation performance is obviously superior to that of a single-plate clutch, the thermal friction loss of the clutch is reduced, and the service life is longer.
In a word, the self-adjusting clutch special for the AMT automobile provided by the invention has the advantages that on the premise that the axial dimension is controlled to be unchanged and the radial dimension is not increased, the torque transmission capability of an engine or a motor is obviously improved, the reliability and the service life of a high-power AMT commercial automobile are improved, and the self-adjusting clutch has a good application prospect.
