Description
Technical field
The utility model relates to a kind of clutch of automobile.
Background technique
Clutch between the motor and gearbox of automobile, and usually and the engine crankshaft flywheel be installed together, the output shaft of clutch is exactly the input shaft of gearbox.Automobile is from the process that starts to walk to go, and the driver can step on or release the clutch pedal as required, motor is separated with gearbox or engages, to cut off or to transmit the power of motor to the gearbox input.
According to the difference of the torque kind of drive, automobile clutch is divided into friction clutcch, magnetic clutch, fluid coupling, and wherein friction clutcch is divided into two kinds of dry type and wet types again.
The dry type friction clutcch is widely used in manual transmission (Manual Transmission; Abbreviation MT), mechanical automatic gearbox (Automated Mechanical Transmission; Be called for short AMT) and double clutch gearbox (Dual Clutch Transmission is called for short DCT).
See also Fig. 1 a, existing dry type friction clutcch mainly comprises friction plate 5, platen 30 and diaphragm spring 2.Wherein, friction plate 5 is loss parts, is used for contacting with flywheel 6 or separating, and follows flywheel 6 during contact and rotates together, does not rotate during separation.An immovable point 20 a bit is fixed in the centre of diaphragm spring 2, and one of which end 2a contacts with release bearing, and the other end 2b then is fixed on the platen 30.
See also Fig. 1 a, this is the schematic representation that friction plate 5 when not wearing and tearing, clutch pedal unclamp.This moment, release bearing did not have active force to an end 2a of diaphragm spring 2, the other end 2b extruding platen 30 of diaphragm spring 2, thus friction plate 5 is pressed on the flywheel 6 the clutch transmits torque.
See also Fig. 1 b, this is the schematic representation that friction plate 5 when not wearing and tearing, clutch pedal are operated.The position of diaphragm spring 2 when the position of diaphragm spring 2 when dotted line representes that clutch pedal unclamps among the figure, solid line represent that clutch pedal is stepped on.This moment a release bearing squeeze film flat spring end 2a of 2; Because some fixed-site in centre of diaphragm spring 2 are at immovable point 20 places; Thereby the right-hand perk of the other end 2b of diaphragm spring 2 in Fig. 1 b, and drive platen 30 and move right, make between platen 30 and the friction plate 5, reach the effect of no impacting force between friction plate 5 and the flywheel 6; Thereby the effect of zerofriction force, clutch are not transmitted and are turned round.
See also Fig. 2, this is the schematic representation that friction plate 5 wearing and tearing backs, clutch pedal unclamp.The position of friction plate 5 wearing and tearing rear film springs 2 is represented in the position of diaphragm spring 2 when dotted line representes that friction plate 5 does not wear and tear among the figure, solid line.Because the thickness attenuation of friction plate 5 makes the other end 2b of platen 30 and diaphragm spring 2 all to the direction of friction plate 5 displacement arranged.Because some fixed-site in centre of diaphragm spring 2 are at immovable point 20 places, thereby the right-hand perk that an end 2a of diaphragm spring 2 can be in Fig. 2.Usually the center fixed point of diaphragm spring 2 less than the arm of force apart from release bearing, for example is 1:3 apart from the arm of force of platen 30.Therefore as long as friction plate 5 has wearing and tearing, the thickness that an end 2a of diaphragm spring 2 is always worn away greater than friction plate 5 to the distance of right-hand perk; Promptly along with the continuous wearing and tearing of friction plate 5, the position of an end 2a of diaphragm spring 2 will be constantly to right-hand perk.
In case let slip the clutch, the actuator between clutch pedal and release bearing can give active force of release bearing, makes an end 2a of release bearing squeeze film flat spring 2.But after friction plate 5 wearing and tearing; Variation has taken place in the position of one end 2a of diaphragm spring 2; This moment need be according to the position of the position adjustment release bearing of an end 2a of diaphragm spring 2, separates bearing when guaranteeing that clutch combines fully not produce the influential active force of diaphragm spring impacting force.
Because the wearing and tearing of friction plate, diaphragm spring generation deformation causes the Separating force of clutch to change.Normally behind the friction disc wear, the Separating force of clutch increases.Use like this that onesize Separating force can not make clutch separation fully when not wearing and tearing.
For improving the problems referred to above that cause owing to friction disc wear, existing various gearboxes all have solution.
The common way of manual transmission is to adjust once the immovable point position of said actuator at regular intervals, can solve the problem that the position of an end 2a of diaphragm spring 2 changes like this, but can't adjust the size of Separating force.
Mechanical automatic gearbox then adopts the self-regulation push rod to adapt to the position of an end 2a of diaphragm spring 2 usually, is aided with the maximum separation power that strengthens.For example, separate bearing output action power when friction plate 5 weares and teares and be not F1 and can satisfy friction plate 5 and be separated with flywheel 6, it is that F2 can satisfy friction plate 5 and is separated F2＞F1 with flywheel 6 that friction plate 5 separates bearing output action power when wearing and tearing fully.The mechanical automatic gearbox active force that will adjust the output of said actuator is always F2 so.The shortcoming of this scheme is: increase self-regulation push rod makes and also can reduce the reliability of whole actuator by complex structure in said actuator.The maximum separation power that strengthens clutch actuating mechanism has improved the requirement to actuator, has improved the car load energy consumption simultaneously.
Double clutch gearbox perhaps adopts automatic compensatory device in said actuator, perhaps in said actuator, add self study, self adaption means.Which kind of solution all exists complex structure, the big problem of control difficulty.

The working principle of the described automatic compensation clutch of the utility model details as follows.
See also Fig. 3 and Fig. 5, this be the described automatic compensation clutch of the utility model when friction plate 5 does not wear and tear, the schematic representation that unclamps of clutch pedal.This moment, release bearing did not have active force to an end 2a of diaphragm spring 2, and the other end 2b of diaphragm spring 2 pushes secondary platen 3, thereby secondary platen 3 is pressed on the flywheel 6.Under the resilient force of holddown spring 40, main pressure plate 4 presses friction plate 5, and friction plate 5 presses flywheel 6, the clutch transmits torque.All there is not active force between protuberance 321, the main pressure plate side plane 43 in the secondary platen sidewall of roller 8 and its both sides at this moment.
See also Fig. 6 and Fig. 7, this be the described automatic compensation clutch of the utility model when friction plate 5 does not wear and tear, the schematic representation that just has been operated of clutch pedal.Fig. 7 is the local enlarged diagram of roller periphery among Fig. 6.This moment a release bearing squeeze film flat spring end 2a of 2; Because the intermediate portion of diaphragm spring 2 is fixed on the housing 1; Thereby the top perk of the other end 2b of diaphragm spring 2 in Fig. 6, and driving secondary platen 3 upwards liftings, the gap appears between secondary platen 3 and the flywheel 6.Under the resilient force of holddown spring 40, main pressure plate 4 still presses friction plate 5, and friction plate 5 presses flywheel 6, the clutch transmits torque.Still there is not active force between protuberance 321, the main pressure plate side plane 43 in the secondary platen sidewall of roller 8 and its both sides at this moment.
See also Fig. 8 and Fig. 9, this be the described automatic compensation clutch of the utility model when friction plate 5 does not wear and tear, clutch pedal continued the schematic representation stepped on.Fig. 9 is the local enlarged diagram of roller periphery among Fig. 8.When secondary platen 3 after the distance of the L1 that moved up under the drive of diaphragm spring 2, under the resilient force of roller Returnning spring 90, all produce active force between protuberance 321, the main pressure plate side plane 43 in roller 8 and the secondary platen sidewall.Particularly, because roller Returnning spring 90 pushes roller 8 toward the below among Fig. 9, in secondary platen sidewall, just produced support force N between protuberance 321 and the roller 8, the direction of this support force N is perpendicular to the inwall of protuberance 321 in the secondary platen sidewall.This support force N can be decomposed into the component N2 that the radially inner component N1 of substantially horizontal and Vertical direction make progress.Under the effect of radially inner component N1; Protuberance 321 extruding rollers 8 in the secondary platen sidewall; Roller 8 extruding main pressure plate side planes 43, thus frictional force upwards on two surface of contact, all produced, and the size of these two frictional force all becomes big along with the increasing of radially inner component N1.Owing to formed a spatial form wide at the top and narrow at the bottom between the inwall of protuberance 321 and the main pressure plate side plane 43 in the secondary platen sidewall; Therefore along with clutch pedal is continued to step on, protuberance 321 constantly increases with the active force (comprising the frictional force parallel with surface of contact on two surface of contact, said support force N) that main pressure plate side plane 43 gives roller 8 in the secondary platen sidewall.When the upward component of this active force was enough to overcome the elastic force of roller Returnning spring 90, roller 8 left roller chassis 7 and moves upward.When the frictional force that makes progress that then gives main pressure plate side plane 43 when roller 8 constantly increases to and is enough to overcome the elastic force of holddown spring 40, main pressure plate 4 also will move upward, thereby main pressure plate 4 and friction plate 5 are separated, and clutch is transmitting torque not.
When supposing that clearance distance between secondary platen 3 and the flywheel 6 is L1, just produced active force between protuberance 321, the main pressure plate side plane 43 in the secondary platen sidewall of roller 8 and its both sides.This moment, clutch pedal can also continue to step on, and main pressure plate 4 still presses friction plate 5.
When supposing that clearance distance between secondary platen 3 and the flywheel 6 is L3, be the state that clutch pedal is floored, this moment, main pressure plate 4 was L2 with clearance distance between the friction plate 5, obvious L3＞L2.
The described automatic compensation clutch of the utility model is described below when friction plate 5 does not wear and tear, the process of release the clutch pedal is opposite with Fig. 6～process shown in Figure 9 gradually:
When just beginning release the clutch pedal, release bearing begins to reduce to the active force of an end 2a of diaphragm spring 2, and the other end 2b of diaphragm spring 2 begins the moved beneath in Fig. 8, drives secondary platen 3 and also moves downward thereupon.Distance between secondary platen 3 and the flywheel 6 begins to reduce from L3.Because of receiving the effect of friction plate 5 resistances, the speed that main pressure plate 4 moves downward reduces after main pressure plate 4 touches friction plate 5.Continue engage the clutch; Secondary platen 3 continues to move downward; The support force N that protuberance 321 gives roller 8 in the secondary platen sidewall in this process begins to reduce, and the pressure that roller 8 and main pressure plate side plane are 43 also begins to reduce, and the frictional force that produces owing to pressure when 43 of roller 8 and main pressure plate side planes is during less than the elastic force of holddown spring 40; Main pressure plate 4 is pressed on the friction plate 5 under the elastic force effect of holddown spring 40 gradually, and clutch begins transmitting torque.
Along with clutch pedal continues to loosen, secondary platen 3 continues to move downward with roller 8, after roller 8 touches roller chassis 7, and roller 8 stop motions, secondary platen 3 continues to move downward, and the distance between secondary platen 3 and the flywheel 6 will be reduced to L1 gradually.After this contact force that interior protuberance 321 of secondary platen sidewall and roller are 8 is reduced to zero.After clutch pedal loosened fully, secondary platen 3 finally was pressed on the flywheel 6, accomplished the clutch cohesive process.
See also Figure 10, this is the schematic representation that the described automatic compensation clutch of the utility model unclamps at friction plate 5 wearing and tearing backs, clutch pedal.This moment, release bearing did not have active force to an end 2a of diaphragm spring 2, and the other end 2b of diaphragm spring 2 pushes secondary platen 3, thereby secondary platen 3 is pressed on the flywheel 6.The thickness attenuation when though friction plate 5 does not wear and tear, under the resilient force of holddown spring 40, main pressure plate 4 still presses friction plate 5, and friction plate 5 presses flywheel 6, the clutch transmits torque.All there is not active force between protuberance 321, the main pressure plate side plane 43 in the secondary platen sidewall of roller 8 and its both sides at this moment.
The described automatic compensation clutch of the utility model has just been stepped on process at friction plate 5 wearing and tearing back, clutch pedal, has been continued to step on process, souththern pine open procedure, in full accord when continuing release process and then not wearing and tearing with friction plate 5.
Why existing dry type friction clutcch can produce the situation that position, the Separating force size of compression zone 2a constantly changes, and is that the elastic state owing to diaphragm spring 2 can change along with the wearing and tearing of friction plate 5.The utility model described automatic compensation clutch has guaranteed that the elastic state of diaphragm springs 2 all is consistent before and after friction plate 5 wearing and tearing, has guaranteed that therefore the position of the compression zone 2a of clutch, Separating force size are constant, has reached the effect of automatic compensation.
This is because the described automatic compensation clutch of the utility model comprises two cover power delivery systems.First power delivery system is external, shows as Vertical direction, is made up of diaphragm spring 2 and secondary platen 3, does not wherein have wearout parts, thereby external force bearing point, stressed big I remain unchanged.Second power delivery system is internal, comprises two power transmission ways again.The first power transmission way is vertical, be made up of holddown spring 40, main pressure plate 4 and friction plate 5, but the wearing and tearing of holddown spring 40 adaptive friction sheet 5 under the clutch pedal releasing orientation changes.The second power transmission way comprises level and vertical two-part, by roller Returnning spring 90, roller take over a business 9, protuberance 321 and main pressure plate side plane 43 are formed in the roller 8, roller chassis 7, secondary platen sidewall.And the inwall of protuberance 321 is the inclined-plane for flywheel 6 in the secondary platen; Main pressure plate side plane 43 is a vertical surface for flywheel 6; The spatial form wide at the top and narrow at the bottom that both form and the combination of roller 8 are used for bearing the processing procedure that clutch pedal is stepped on, and the influence that not whether worn and torn by friction plate 5.
More than be merely the preferred embodiment of the utility model, and be not used in qualification the utility model.For a person skilled in the art, the utility model can have various changes and variation.All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
