Description

[Detailed description of the invention] torque converter The present invention consists of a nine-impeller member and a nine-impeller member that is kicked into a round shape that rotates separately with a common axis oys*. , turbine members, reaction members, and steel members together act as a trombone against the operating fluid. Id-like O+S work■Route (t@r*14・1ma・rklmg　elr・-ro) is limited However, the Kubin member is stationary or rotates at a low speed compared to the #0 speed of the blade foot. When rotating, the torque applied to the turbine/lHt by the housing acts on the impeller. The algebraic difference between the two 0) Reaction in the opposite direction seen by the Al1 body against the reaction member being held) The can part # interacts with the housing in the operating circuit so that it is corrected as follows: In order to do so, this relates to a type of dynamic source pressure type torque turn parter that has guide vanes. . As the (exit) interference IIL of the turbine components increases, the torque will become different and work harder. , so the reaction) Ruta, the reaction Tortuff 1I & 4a K decreases, and then the eclipse K The so-called connection range K11 (with an output speed of 90 degrees of the input speed) is reached. decreases to To avoid the consequent further reduction in output torque, the reaction The moving member is allowed to rotate in the direction determined by such a negative O reaction torquer. ・The II controller acts as a housing joint.・If the output speed is below the connection range. When lowering, the reaction member is again held stationary and the output torque rises above the input torque. rise・ Various designs of such converter fittings are widely used. Generally, the reaction member is It is held against rotation in one direction, and the horizontal roller and inclined table are held in the other direction. Freewheel equipment of either menya type or spray type It is allowed to rotate depending on the position. For successful work over a long lifespan The two-way system described above requires that each set of rollers or wheel chocks enter the work at the same time as the other. complex geometries to ensure that the work load is shared between them. Requires high quality materials and precision manufacturing operations.

In the torque converter joint based on the developed vsox system, the stationary structure and the reaction member are According to the engagement of the abutment surfaces rotationally connected to each other, the reaction member is unidirectionally The converter fittings are held against rotation as the output speed increases over the coupling range. As the contact surface is separated in the axial direction, the output speed decreases below the coupling range. It includes means for engaging the abutment surface when lowered.

The relative axial movement between the six contact surfaces leading to engagement is achieved by one member carrying one set of contact surfaces. and the reaction member by a helical restraint of limited length. . Relative movement along the restraint is determined by the dog torque applied by the dog means. You can start anyway.

Conveniently, the abutment surfaces are formed by tooth surfaces of a toothed clutch. desirable Ino is a toothed clutch that helps the axial separation of the toothed clutch when the output speed increases to the coupling range. The surface on the opposite side of the clutch is inclined with respect to the shaft.

According to another aspect of the invention, a torque converter/luxury coupling is provided, the In some cases, the guide vanes of the reaction member are inclined with respect to the axis, where the reaction member is restrained in the axial direction. KJI is installed for limited movement and cannot be applied by liquid onto the reaction member guide vanes. The axial movement of the reaction member in response to the nine axial components of the reaction member The clutch is arranged to engage and disengage the clutch.

The converter fitting is then Apply a dog torque on the reaction member to increase the axial force exerted on the reaction member. Rounding dog means may advantageously be included. Desirably, the speed is increased 1. The dog means is connected to the reaction member so that the Kl' lag torque is reduced or eliminated when is to respond to the rotational speed of the motor. The dog means rotates with the reaction member. KL including the attached dog member to receive centrifugal force against elasticity; Pushing the dog members inwardly into frictional contact with a fixed external rotating surface, such It is advantageous to increase the centrifugal force which tends to reduce frictional contact.

4 l In the λ embodiment, the dog member is mounted 9 within a cavity in the nop of the reaction member. bites an elastic split ring or band that is held in place and brings it into frictional contact with a non-rotating rotating surface; It is forced to rotate K11 with the reaction member, but it is not possible to rotate it in the axial direction. As the angular velocity of the reaction member increases, the cylinder X-ray band , positioned away from contact with non-rotating surfaces.

It is desirable that a torque converter coupling encompass both aspects of the present invention.

If applicable, use a closing clutch to selectively lock the input member to the output member. You can also prepare.

＠　'j, shown in the figure Nine Torta Converter Fittings Co., Ltd., generally constructed from conventional construction. , it is the impeller member 1. Turbine member 2. and - together with the trochoidal operating circuit 4. It includes a limiting reaction member 3. Three elements 1, 2.3 are guide vanes 1a e 2 a m 3 a is formed together with one set of guide vanes, and each set of guide vanes has an annular core part. Minutes 1, 2, 3bK end, these parts put together the annular core for the operating circuit 4 to form.

According to conventional convergence means, the guide vanes are angled and the blades are bent to form a condenser. It has the required performance of a converter joint, and especially the 8m guide vane of the reaction member 3 is 4, it is inclined to the axis of the joint.

In this embodiment, an external circuit defines the radially outermost portion of the operating circuit. The impeller 1, which is assembled from various components including the rolling casing 6, has an input section. The steel member 80 is fastened to the drive 7/shifter, and the iron member has a sleeve portion 9. engages a recess in an output member of an internal combustion engine (not shown), the internal combustion engine having a Mayer 7 ram. It is connected to the drive flange 7 via a member (not shown).

Turbine member 2, flange 1 connected to output shaft 12 by spline 13 I bolt is tightened to 1.

The inner (left hand) end 14 of the shaft 12 is pivotally supported by a ball bearing 15 in the input member 8, The radial roller thrust bearing 16 is installed at the connection between the 7〉y-gear 11 and the input member 8. It is being The other end of the shaft 12 is pivoted or otherwise supported in a stationary casing 17. The casing includes a sleeve portion surrounding the shaft 12 with a clearance. It has 18. Sleeve 19a, in its half, with straight axial splines 20 and the other half is mounted on the sleeve portion 18 by a suitable bearing 22. is pivotally supported on the hub portion 21 of the flange 11 by. The sleeve 19 is The impeller assembly 1 and the turbine are is placed axially with respect to the ring assembly 2.

The reaction member hub 25 is rotatably attached to the sleeve member 19 by a pair of screws. The flat bushing also allows the knob to move axially on the sleeve 19.

The radially outer surface of the nozzle 25 is fitted with a sedge 2-in to form a central hole in the reaction member 3. It engages a corresponding spline 27 in the hole. 1 engaged during the perforation in the reaction member 3 A pair of spring rings 28 engages opposite end faces of the hub 25 to position the latter with respect to the reaction member. urge

The range of axial movement of the hub 25, and thus of the reaction member assembly, is determined by welding or other means. affixed to sleeve member 19, each forming a race for a respective bearing 24, 23; It is defined by opposite end rings 29 and 30 forming the same. End R/G 30 and No. The proximal end of the tap 25 is formed by a complementary set of shallow claw teeth 31 and 32. has been done.

As can be seen from Figures 3 and 4, each clutch tooth has 19 flanks. k) a substantially radial and axial abutment surface 33 on the other flank 34 of each tooth; is relatively long and gently sloped. The tips 35 of the teeth are narrow and flat, as well. A flat and narrow area 36 is formed at the root of the tooth of the 7th rank 33° 34.

During operation, when the converter coupling operates as a torque converter, the reaction member blades The direction of liquid flow through the roots 3a is at an angle to these vanes and the axial force on the reaction member assembly 3, and the assembly 3 (to the right in the figure) to bring the two sets of teeth 31 and 320 into full alignment. Make it. In this case, the reaction member 3 is connected to the mutual engagement of the contact surfaces 33 on the two sets of clutch teeth. As a result, it is prevented from rotating.

When the speed of the output shaft 12 is out of the connection range and/or the closing clutch (not shown) When engaged and the driving force is directly transmitted between the input member 8 and the shaft 12, the housing The direction of the force exerted on the guide side s3m is that the circumferential component force is reversed and 33 changes to no load, the inclined surfaces 34 ride on each other, and the reaction member 3 Helps move to the left in Figure 1 and wX2, thus the engagement of $ll31,32 This allows the reaction member to rotate in the same direction as the input member.

When it is necessary to move the reaction force **ts in the axial direction, the casing allows it to move onto the reaction member 3. The dog torque that resists the 30 rotations of the reaction member increases the force exerted by the elastic pan P. 41 and cut at position 42 on its periphery. and is lined with a suitable friction material 43, which is in friction with the outer surface of the sleeve member 190. Make contact.

The pan P41 is located in the oil-shaped recess 44 in the hub 26 and in the slot in the hub. 46 in the Beg 4sO quarters to prevent rotation and slots. ) 46 is ten fi! reaction member 3 with respect to peg 4SK, having an axial length at P1; A must! On the outer surface of the sliding member 43 and the sleeve member 19, which allows for axial movement. 4 Seen elastic company provides necessary wtkr torque to resist reaction member 30 rotations Therefore, during the transition between locking and unlocking of the reaction member and vice versa, the reaction member 3 11i can be selected to determine the axial force exerted on the reaction member O1 1 When the rotational speed increases, the centrifugal force will be reduced to the allowable value or the dog torque will be removed. Push the band 41 against its internal elasticity until it is reduced. When the clutch teeth 31 and 32 disengage and allow the reaction member to rotate freely, Their distal surfaces 36 are only separated by a small distance to prevent contact. Although necessary, the tip surface 3s of the Kosho 32 may be damaged in a certain transition state. It is possible to rotate by contacting the tip surface of the tooth 31. In the embodiment shown in FIGS. 5 to 7, the reaction member 3 is located above the sleeve 51. grooved (with a straight spline 52), 2. Chi tooth 32 2 sets of spiral teeth 54 and 5502 are formed on its outer surface. These teeth engage and disengage the sleeve s10 clutch teeth 31 and 32. , by a helical movement of the hub 25' on the sleeve 51.

Therefore, there is no need to allow a specific axial degree of freedom for the reaction member 3, and therefore, The reaction member 3 has a spring ring 28 and an axially inner side of the thrust bearings 23 and 24. Due to the O-engagement with the radially outward extension SSS of the race, it is located in the axial direction and the long part of the skeleton 56 lean against both ends of the sleeve 510.

As the output speed moves through the coupling range, the reaction member 3 reverses its direction of rotation. 1 hub 25 to initiate engagement of clutch teeth 31 and 32 when attempting to houses an elastic friction band 57 in its internal annular recess 44'; It is divided by a barrier 1158 at one point on the periphery and frictionally engages with the sleeve member 19. Ru. One peg 59 is screwed into the hub 25' and near one end of the friction band 57. It has a rounded diameter portion 60 that engages in a slot 61 formed in the. therefore friction The ζO end of the band is moored to the hub against rotational movement, thus allowing the pan P57 and the Despite the frictional engagement with the blade member 19, axial movement of the knob is permitted.

Referring to FIG. 7, it can be seen that the clockwise rotation of peg 59 (and hub 25') Rotation increases the frictional engagement between band 57 and sleeve member 19 and thus ′ increases the dog torque applied by band 57 on 6' and the counterclockwise movement of peg 59 reduces the frictional engagement of the motor III gun P57. , thus reducing the friction dog applied on No. 2 B'. Therefore In addition, the mooring end of the band 57 is rotated in the direction in which the reaction member rotates in the opposite direction with respect to the input rotation. A relatively large dog is chosen to result.゛Sc f’y in 53 and tooth 54, The handling of 55 further includes repulsion through the teeth 54 and 55 and the spiral sedge line 53. Transferring this dog torque to the moving member 3 is shown in FIG. ' is selected to produce an axial force on the jaw 32 to engage the tooth 31.

applied by the housing on the reaction member 3 as the power output rises through the coupling range. The torque is now in the forward direction and the resulting forward rotation of the reaction member 3 is Pull knob 25' to the left in Figure 5 to separate clutch teeth 31 and 32. 31 and 320, which have been reversed and reduced and are still valid. It is performed by dog torque assisted by the slope. 1/in the forward direction As the rotational speed of the reaction member 30 increases, the band device 7 expands in the radial direction and wears out. Reduce or eliminate chafing.

Connection between pad 1 57 and hub 2 B' as in the embodiment of FIGS. In this case, one peg, such as peg 45 in FIG. (by fixing it to the pin 57), in which case the I-P2SI can be A slot is formed for accommodating the hub, and the slot extends fully in the axial direction of the hub. of sufficient length to allow the necessary axial movement of the hub.
