Abstract
The invention provides a clutch of an automatic gearbox with a simple structure and a small axial size. The clutch comprises an inner hub and an outer hub, wherein a supporting arm, which is disposedon a rotating shaft of the inner hub, comprises a side wall vertical to the rotating shaft of the inner hub and a level wall parallel to the rotating shaft of the inner hub. The inner wall of the outer hub and the level wall of the supporting arm are connected with a clutch plate by a spline. A piston is disposed between the level wall and the rotating shaft of the inner hub. A piston claw on thetop of the piston presses against the clutch plate by bending towards the level wall and getting around the level wall. The clutch fully uses the axial space in the inner hub, so the axial size of thewhole clutch is more compact and the size of gearbox is decreased for the purpose of conveniently arranging the gearbox on automobile. The invention further provides a cooling structure of the clutchto completely cool the clutch, ensure the working efficiency of clutch and prolong the service life of the clutch.
Description
Technical field
The invention belongs to field of automobile, specially refer to the clutch of automatic gearbox.
Background technique
The gear of automatic transmission by a plurality of planetary gear set, transmit the friction element of rotating speed and moment of torsion, form as each clutch, break and servo-system thereof, send output shaft to after rotating speed that it transmits fluid torque converter and the moment conversion, to drive automobile.The shelves number of speed changer is many more, the speed ratio of speed changer just can design unreasonablely thinks, vehicle also just can have better fuel economy and cornering ability, but gear is many more, power transmission line from the speed changer input end to output terminal is just long more, make the size of whole speed changer, particularly axial size become big, this just makes the front deck space nervous more.In addition, to disperse the life-span for clutch be very crucial to the heat of clutch in the automatic transmission, after particularly clutch miniaturization, gear are complicated, its cooling is just more important, therefore clutch designing must be considered cooling structure, and guaranteeing has enough cooling liquids can reach clutch plate.
Summary of the invention
The objective of the invention is to propose a kind of simple in structure, clutch that axial dimension is little.
Hub and outer hub in the clutch of automatic transmission of the present invention comprises, key is that the rotating shaft of described interior hub is provided with support arm, described support arm comprises perpendicular to the sidewall of interior hub rotating shaft and the horizontal wall of hub rotating shaft in being parallel to, the inwall of described outer hub, the horizontal wall of support arm are connected with clutch plate by spline, between described horizontal wall and the interior hub rotating shaft piston is installed, the piston wall pawl of described piston head is walked around horizontal wall and is offseted with clutch plate to the outer lateral buckling of horizontal wall.
This piston is placed under the clutch plate, be installed on the arrangement among the hub in the clutch, because piston and clutch plate axially not on same horizontal plane, therefore both axial dimensions can overlap to a certain extent, make full use of the axial space of hub in the clutch, make that the axial dimension of whole clutch is more compact.
The sidewall top of described support arm projects upwards in horizontal wall, and the sidewall top of described clutch plate and support arm offsets.Clutch plate is undertaken spacing by the sidewall top of support arm at axial direction, need be outside clutch snap ring be installed on hub or the interior hub clutch plate is carried out axial limiting, has reduced the number of parts of clutch, makes that the assembling of clutch is simple more, convenient.
By further reducing being taken up space of clutch, above-mentioned clutch is provided with two outer hubs in the same way, described two outer hubs are arranged above and below, described support arm is provided with two horizontal wall in the both sides of its sidewall, be provided with piston under each horizontal wall, the inwall of each outer hub, the horizontal wall of support arm all are connected with clutch plate by spline.Such work that clutch is two planetary pinion set of pieces of may command makes the required clutch quantity of automatic transmission reduce, thereby makes the physical dimension of speed changer compact more, makes the front deck spatial arrangement convenient.
The concrete set-up mode of piston is as follows: described piston is slidingly mounted in the chamber that forms between interior hub rotating shaft, support arm sidewall and the support arm horizontal wall, the baffle plate of piston by a snap ring axial limiting in the interior hub rotating shaft in the piston outside.Just formed a chamber between the baffle plate of piston and interior hub rotating shaft, the piston like this, after filling with hydraulic oil in this chamber, piston just moves to the direction of support arm sidewall under the effect of hydraulic oil, the piston wall pawl is pushed clutch plate to the direction of support arm sidewall, the friction plate of clutch and the combination of antithesis sheet, make the interior hub and the outer hub of clutch form an integral body, thereby transmission of power hub to clutch that will come from hub in the clutch, again by clutch outward hub be passed to related elements or other component of planetary gear set.
For solving the problem of clutch heat radiation cooling, the interior hub rotating shaft of above-mentioned clutch has oil inlet hole, is penetrated with oil-through hole on the horizontal wall of described support arm, and described outer hub has the oil outlet that runs through.When clutch is worked, under action of centrifugal force, in the chamber that forms between hub rotating shaft in cooling liquid enters by oil inlet hole, piston, support arm sidewall and the support arm horizontal wall, enter into the clutch plate place by oil-through hole then, clutch plate is cooled off, throw away clutch by oil outlet at last, finish cooling clutch.
The sidewall of described support arm and horizontal wall are provided with many fluid passages, and the two ends of described fluid passage communicate with oil inlet hole and oil-through hole respectively.On the sidewall of support arm and horizontal wall, special fluid passage is set, can carry out a well guiding to cooling liquid, make the lower cooling liquid of temperature that has just entered clutch can enter into the clutch plate place as early as possible, clutch plate is cooled off, improve cooling effect.Described fluid passage can be made of the thin walled cylinder body on sidewall that is fitted in support arm and the horizontal wall.
Described clutch plate is provided with radial groove, can accelerate cooling liquid flowing on clutch plate like this, strengthens the area of contact of cooling liquid and clutch plate, improves cooling effect.
The clutch of automatic transmission of the present invention is by placing piston under the clutch plate, be installed on the arrangement among the hub in the clutch, make full use of the axial space of hub in the clutch, made that the axial dimension of whole clutch is more compact, made things convenient for the layout of clutch on speed changer; The present invention also provides the cooling structure of above-mentioned clutch in addition, so that clutch can obtain sufficient cooling, guarantees the work effect of clutch, prolongs the working life of clutch.
