Abstract

The invention provides a clutch assembly and a transmission. The transmission utilizes a three clutch module. The clutch module may be pre-assembled before it is assembled into the transmission. All three clutch packs are splined to a common shell at their outer diameter. One of the clutch pistons passes through openings in the clutch pack of one of the other clutches. The common shell is fixedly coupled to a hollow shaft through which the transmission input shaft protrudes. Pressurized fluid to engage the three clutches is routed through axial passageways in the input shaft.

Fig. 2 is three clutch modules that the integration comprising clutch 72,74 and 76 is shown.Quill shaft 90 is transfused to axle 60 and supports, and is fixedly combined to shell 64.Between the sealing elements, the fluid of pressurization flows into the passage in quill shaft 90 from the axial passage input shaft 60, each passage of quill shaft is associated with the special modality in quill shaft.When the molding, some passages can by casting in quill shaft.Other passages are holed after shaping.Some passages axially extend at different circumferential position.Some passage partly can be limited by independent inserting member.
Clutch hub 92 is fixedly joined to sun gear 56.Clutch hub 94 is fixedly joined to the quill shaft 96 being fixedly joined to sun gear 46 and ring gear 38 successively.Clutch hub 98 is fixedly joined to ring gear 48.Clutch hub 98 is by thrust-bearing axially location, and clutch hub 98 is separated with the pad 100 of being located by sun gear 46 with clutch hub 94 by thrust-bearing.
Each clutch comprises clutch pack, and described clutch pack comprises friction plate, at least one in platen and reaction plate.Such as, clutch 72 comprises key and is connected to pressure disk 104 and the reaction plate 106 that the friction plate 102 of wheel hub 92 and key are connected to shell 64.If there is multiple friction plate, the separator disk 108 that they and key are connected to shell 64 interts to be arranged.Snap ring 110 stops reaction plate 106 axial motion.When piston 112 moves to right side, clutch pack is pressed together, and moment of torsion is transmitted between wheel hub 92 and shell 64 by frictional force.
Fluid is provided to the room 114 formed by piston 112, shell 64 and quill shaft 90 by a passage.When the fluid in room 114 is pressurized, it is towards platen 104 forces piston 112.The axial force extruding clutch pack applied by piston, makes moment of torsion be transmitted between wheel hub 92 and shell 64 by frictional force.When pressure is released, Returnning spring 116 forces piston 112 away from platen 104 to be separated with clutch 72.Along with quill shaft 90 rotates, the fluid in room 114 is compressed by causing the CENTRIFUGAL ACCELERATING of the unexpected part joint of clutch 72.In order to offset this possibility, the sustainable balance cylinder 118 to being limited by piston 112, quill shaft 90 and reaction member 120 provides uninflated fluid.
Clutch 74 similar.Friction plate 126 key is connected to wheel hub 98, and arranges with reaction plate 128, separator disk 130 and platen 132 is interspersed.Another passage in input shaft 60 provides fluid to the room 122 formed by piston 124, shell 64 and quill shaft 90.To the pressurized with fluid in room 122, clutch 74 is engaged.When pressure is released, Returnning spring 134 driven plunger 124 away from platen 132 to loosen the clutch 74.Can uninflated fluid be provided constantly to offset centrifugal pressure in the balance cylinder 136 limited by piston 124, quill shaft 90 and reaction member 138.
The piston 124 that clutch pack for clutch 76 is suitable for being allowed for clutch 74 extends through described clutch pack.Reaction plate 140, separator disk 142 and platen 144 are connected to shell 64 at their outward edge key.Each in reaction plate 140, separator disk 142 and platen 144 has opening between the region that itself and friction plate 146 have a common boundary and key.Piston 124 does not need circumferentially to extend whole.Contrary, it has the finger portion of the opening reaching reaction plate 140, separator disk 142 and platen 144.This is feasible, because these elements always rotate with mutually the same speed.Clutch 76 is by providing the fluid of pressurization and combined to the room 148 limited by piston 150, quill shaft 90 and reaction member 138.When pressure is released, Returnning spring 154 forces piston 150 to get back to disengaging configuration.In the balance cylinder 156 limited by piston 150, quill shaft 90 and reaction member 152, not pressurized fluid can be provided constantly to offset any centrifugal joint trend.Quill shaft 90 comprises the axial passage of the fluid that transmission is not pressurized from the independent axial passage input shaft 60 to room 156,136 and 118.
This three clutch modules can be outside case of transmission assembling and as cellular installation sub-component in the transmission.Sub-component can comprise quill shaft 90, shell 64, piston 124,159 and 112, reaction member 152,138 and 120, and for the platen of clutch 72,74 and 76, reaction plate, separator disk and friction plate.The assembling of module is started by mounting casing 64 on quill shaft 90, and installs snap ring to stop axial motion.Then, piston 112, Returnning spring 116 and reaction member 120 are installed, and by snap ring, piston 112, Returnning spring 116 and reaction member 120 are fixed in quill shaft 90.Next step, platen 104, separator disk 108 and reaction plate 106 and friction plate 102 are interted and arrange that ground key is connected to shell 64, wherein friction plate 102 keeps the internal diameter not being fixed to platen 104, separator disk 108 and reaction plate 106.Snap ring 110 is by position for the clutch pack about clutch 72.From the other end work, piston 124, Returnning spring 134 and reaction member 152 are installed and pass through snap ring fixed piston 124, Returnning spring 134 and reaction member 152.Then, piston 150, Returnning spring 154 and reaction member 152 be installed and pass through snap ring fixed piston 150, Returnning spring 154 and reaction member 152.Finally, the clutch pack key about clutch 74 and 76 is connected to shell 64 and is fixed.Wheel hub 92 can be installed in case of transmission before sub-component, and was connected to friction plate 102 along with the fitting key of sub-component.No matter be that before or after installation subassembly, clutch hub 94 and 98 can be connected to friction plate 146 and 126 by key respectively.
