Definitions
- the assistance spring for example in the form of a Belleville washer, can bear on the cover and on the internal end of the diaphragm fingers.
- the Belleville washer which acts on the wear take-up device, is a negative Belleville washer; the load which it provides decreases when the height of its truncated cone decreases then increases - while the other washer
- the flywheel 1 dorsally has a friction face 10 and is shown here partially, knowing that in known manner it has holes centrally for its fixing using screws to the driving shaft.
- the flywheel 1 is in one piece being of moldable material just like the pressure plate 3 which frontally has a friction face 30 facing the friction face 10 of the flywheel 1.
- the bearing zones are offset axially with respect to the central part of the disc 23, the central bearing zone, of large extent, being connected to said central part by a tangential fold, while the peripheral bearing zones are connected to said zone central bearing by oblique folds
- the central bearing zone of large extent, being connected to said central part by a tangential fold
- the peripheral bearing zones are connected to said zone central bearing by oblique folds
- the flywheel 1 can be in two parts and include a support flange fixed at its internal periphery to the driving shaft and at its external periphery to a reaction plate having the friction face 10.
- the cover 8 can then be assembled to the flywheel 1 in two parts using axial orientation lugs coming from its cylindrical peripheral skirt 82. These lugs, in the shape of tenons, are then engaged in mortises formed at the external periphery of the reaction plate or of the support flange.
- the free section of the legs, forming the aforementioned fixing means 81 of the cover 8, can be fixed by crimping, folding down or welding, to the flange or to the reaction plate, as described for example in French patent application 95/12523 filed on October 24, 1995.
- the first tree possibly being a driven tree and the second tree being a leading tree.
- the pressure plate 3 is linked in rotation with the cover 8 by elastic tabs 9 allowing the pressure plate 3 to move axially relative to the cover 8.
- the pressure plate 3 is therefore fixed in rotation with the cover 8 and the flywheel 1, while being axially movable relative to them.
- the tongues 9 are here of tangential orientation and urge the pressure plate 3 towards the bottom 80 of the cover.
- These elastic tabs 9 are therefore axially acting and have a return action.
- the tongues may be of radial orientation.
- the external cylindrical skirt 82 of the cover 8, connecting the bottom 80 to the radial fixing rim 81 is locally perforated for passage of tabs 91, which has the pressure plate 3 projecting radially.
- the tangential tabs 9 are fixed to the 'one of their ends to the legs 91 and at their other end to a radial area 83 of the cover. These tabs 9 are distributed regularly circumferentially, in a known manner; their number, as well as that of the legs 91, depends on the applications, knowing that, for passenger vehicles, use is generally made of three tongues 9 or groups of tongues.
- the first Belleville washer 4 is supported at its outer periphery on the pressure plate 3, as described below. This washer 4 is inclined, in the direction of the cover 8, its concavity being directed towards the pressure plate 3.
- the second Belleville washer 6 rests at its outer periphery on a stamped 85, split or not, formed in the bottom 80 of the cover 8 and directed axially towards the pressure plate 3.
- the second Belleville washer 6 is inclined in the direction of the plate pressure 3, in the opposite direction to the first washer 4, its concavity being directed towards the bottom 80 of the cover 8.
- the clamp 50 here of annular shape, is elastic and elastically tightens the washers 4 and 6 in contact with the rod 5 while being in contact by its branches with the external face of said washers.
- This clamp can alternatively be split into clips.
- the clamp opens or closes.
- the declutching device 7 comprises a transverse plate 41 carrying at its outer periphery the annular rod 5 of force transmission; the transverse plate 41 is connected by its internal periphery to a sleeve 42 mounted to slide axially.
- This declutching device 7 is provided to counteract and overcome at will the elastic action of the Belleville washers 4 and 6 with a view to loosening the friction linings at will.
- the Belleville washers 4 and 6 enable said linings 20, 21 to be clamped between the plates 1 and 3 and constitute the engagement means with axial action urging the pressure plate in the direction opposite to the bottom 80 of the cover 8.
- the sleeve 42 of the declutching device 7 can be moved, for the purpose of the declutching operation, in one direction or the other, that is to say in the direction of the arrow F, the clutch being of the type pulled, or in the opposite direction to that of arrow F, the clutch being of the pushed type .: this depends on the choice of the relative characteristics of the first 4 and second 6 Belleville washers.
- one of the Belleville washers tightens the clutch and is designated below by tightening washer; the other Belleville washer provides assistance with declutching and is designated below as an assistance washer.
- the clutch is shown engaged under the load of the second Belleville washer 6, of assistance, transmitted to the pressure plate 3, via the force transmission means 5, here in the form of a rod, by the first Belleville washer 4 for clamping in support by its external periphery on the support zones 1 14 described below and by its internal periphery on the annular stop 32.
- the washer 6 When acting on the sleeve 42 in the direction of the arrow F, the washer 6 is somehow compressed, its load exerted increasing and its internal periphery being brought closer to the bottom 80 of the cover 8; this compression is assisted by the clamping washer 4 which releases the stored energy, in the engaged position, under the effect of the washer 6, predominant, during the clutch operation.
- the compression stroke of the washer 6 is limited at the disengaging device 7 or, as shown, by a stamped 86 of the bottom 80 of the cover with which the washer 6 comes to cooperate at the end of the clutch release operation.
- the wear take-up device 90 comprises ramp means 111 arranged circumferentially constituted by a sheet metal ring cut and stamped so as to have ramps arranged circumferentially; said ring also has bearing zones 114 constituted by the rounded upper edge of stamped arcs of a circle centered on the axis of the clutch and placed here radially on the outside with respect to the ramps.
- the pressure plate 3 has, here from molding, on its face turned towards the bottom of the cover 8, studs 104 distributed circumferentially at a distance from one another which corresponds to that which circumferentially separates two successive ramps, the studs 104 being intended to cooperate each with a ramp.
- One of the bearing zones 114 of the ramp means 111 is extended at its external periphery by a flange parallel to the axis of the clutch ending in a transverse return, that is to say extending in a plane perpendicular to the axis of the clutch, provided at its periphery with a toothing 118.
- the axis of the ratchet wheel 120 is rotated by a support 112, of cut and folded sheet metal, U-shaped having a core and two wings intended to support the axis.
- the support 112 is adapted to receive an elastic member
- the 131 in the general form of a stick, each end of which has an inward return; more specifically, the longer length of the butt end carries a control tongue 135; the portion of the shortest length of the stock has a return 136, called a non-return pawl, which extends generally parallel to the control tongue 135 while being at a distance from the latter so that, when the elastic member 131 and the ratchet wheel 120 are mounted in the support 112, the non-return pawl 136 and the control tongue 135 each cooperate with a tooth foot, the two teeth concerned here being practically diametrically opposite.
- a helical compression spring is placed between the ratchet wheel 120 and an arm of the support 112, being wound around the axis; the worm 13 and the ratchet wheel 20 are cut in one piece.
- the helical spring constitutes the elastic take-up means; the ratchet wheel 120 is in line with the non-return pawl 136 which, by cooperation with the inclined teeth 121 of the ratchet wheel 120, prevents the ratchet wheel 120, as well as the worm 113, from turning in the opposite direction to that of the hands of a watch, compared to the figure.
- the support 112 carrying the ratchet wheel 120, the worm 113 and the helical spring, being integral with the cover
- the first washer 4 moves relative to it during declutching and re-clutch operations; the first washer 4 carries at its periphery a radial appendage said actuator 145 extending radially outside to cooperate with the elastic member 131; it will be understood that, thanks to this arrangement, during the tilting of the first washer 4 during declutching and re-clutch operations, the actuator 145 moves from the right to the left, relative to FIG.
- the game take-up device which has just been succinctly described operates as explained in the above-cited application with reference; thanks to the take-up device 90, the two washers 4 and 6 keep the same position, in the engaged position, whatever the wear of the linings 20, 21.
- the sheet metal ring of the ramp means 111 which carries the teeth 118, is centered at its internal periphery by a cylindrical step 303 formed in the pressure plate 3; said ring has, towards its inner periphery on the cover side, the bearing zones 1 14 with which the first washer 4 cooperates through its inner periphery.
