Definitions
- the invention relates generally to torque converters, more particularly to a torque converter blade, and more particularly to a self-locking blade for a torque converter.
- Hydraulic torque converters are used to change the ratio of torque to speed between the input and output shafts of the converter and have the automotive and marine propulsion industry by providing hydraulic means for transmitting energy from a motor to a drive mechanism, e.g. to the drive shaft of an automatic transmission, and to simultaneously compensate for power peaks of the engine revolutionized.
- a torque converter disposed between the engine and the transmission includes three main components: an impeller sometimes referred to as a pump, which is directly connected to the housing of the torque converter and thereby to the crankshaft of the engine; a turbine similar in structure to the impeller but connected to the drive shaft of the transmission; and a stator disposed between the impeller and the turbine, which deflects the flow of hydraulic fluid exiting the turbine and thereby supplies additional motive power to the pump.
- impeller blades are mounted in slots in an impeller shell.
- the housing shell is formed, for example by punching, and then the slots are stamped in the housing shell.
- the slots can be punched in a flat GeHouseschalenrohteil and then molded the housing shell to the actual impeller shell.
- the housing shell must be arched to draw material to the center of the housing shell to prevent thinning of the material during the deformation process. Therefore, it is cheaper to slit after Embossing the housing shell.
- slots are stamped after the housing shell is formed, tighter tolerances can be maintained than if the slots are coined prior to the formation of the housing shell.
- slots are normally stamped perpendicular to the face of the shell, for example using a Koppy machine. The vertically formed slot and the shape of the blade tend to hold or snap the blade within the slot, and thus within the shell, to prevent detachment from the shell until it can be cleaned and soldered or welded at the intended location.
- the operation and maintenance of Koppy machines is complex, so that other embossing options are desirable, for example, the embossing of vertical slots.
- the blades need only be simply inserted into the slots during assembly.
- slits of this type can be stamped with less effort, and the mounting of the blades in the housing shell can be done faster, but the vertical slot surfaces are all in the same plane and have no surfaces for engaging the blade in the slot.
- the blades loosen easily by merely abutting the blade and / or the housing shell.
- the width of the slots can only be as small as the material thickness of the housing shell, since the edge of the material is substantially sheared when embossing the vertical slots.
- the stamping tool or the stamp must be thick enough so that the tool is not unusable.
- the positioning of the blades within the slots is only the first step in the assembly of the impeller.
- Other steps include positioning a turbine ring so that certain blade tabs protrude into slot-shaped openings within the ring, creating the assembly through a rolling process so that the blade passes through their tabs are snapped onto the turbine ring, washing the assembly to remove oil and rust inhibitors used during punching, inserting the washed assemblies into cages, machining the cages, and brazing the washed assemblies.
- the production of impellers can result in up to fifty percent (50%) scrap as blades fall out during washing and rolling.
- a fitter receives no feedback as to whether a bucket is properly seated because there is no resistance between the bucket and the slots.
- a shovel that is a means for supporting the blade during the entire processing of the assembly in a slot that provides feedback on the proper fit of the assembly.

- 1 shows a perspective view of the impeller 20 of a torque converter including a housing shell 22 having a plurality of slots 24 with impeller blades 26 installed therein.
- Each blade 26 includes a tongue 28.
- the plurality of tongues 28 are disposed within respective slots 30 of the central ring 32.
- the assembly is subjected to a rolling process to bend over the plurality of tongues 28 shown in FIG. 1 and thus to support the plurality of blades 26 in the central ring 32.
- the impeller 20 is washed to remove any dirt, oil, chips, etc. that may have accumulated in or on the impeller 20 during machining.
- the blades 26 travel along the edges 36 of the blades 26, i. along the adjacent edge between the blades 26 and the housing shell 22, soldered to the inner surface 34 of the housing shell 22.
- FIGS. 2-9 is a cross-sectional view of the impeller 20 of a torque converter having a plurality of slots 24 disposed on a first peripheral surface of the housing shell 22 of the impeller, while FIGS. 3 and 4 are enlarged cross-sectional views of the portions 3 and 4 of FIG. 2, respectively which show a slot with a bent tongue of the impeller blade 26 disposed therein.

- FIG. 8 is a side view of a second embodiment of the impeller blade 26 that includes a protruding tongue 42
- FIG. 9 is a rear view of the embodiment of the impeller blade 26 shown in FIG. 8.
- Slits 24 are arranged on a circumference defined by the diameter 44, slots 46 are arranged on a circumference defined by the diameter 48, while slots 50 are arranged on a circumference defined by the diameter 52.
- the positions of the slots 24, 46 and 50 are of great importance because the efficiency of the impeller 20 depends on the proper placement of the blades 26 on the inner surface 34 of the housing shell 22.
- the prior art teaches the formation of slots by punching the slots perpendicular to the metal surface such that a portion of the material that can support an inserted impeller blade remains at the entrance of the slot.
- the slots 24, 46 and 50 are formed by punching operations parallel to the axis of rotation 54 of the housing shell 22.
- other means are possible, e.g. Laser cutting or mechanical cutting, and those skilled in the art will appreciate that such means are within the spirit and scope of the claimed invention.
- the blade 26 is installed by inserting the tongue 40 under compressive stress in the first slot 24 and then by inserting the tongue 56 in the slot 46 and the tongue 58 in the slot 50 in the housing shell 22 so that the blade 26 is held within the housing shell 22.
- insertion under compressive stress is meant that a tongue and one or more walls of a slot touch and normal forces occur between the tongue and the walls. That is, the tongues are pressed into the slots so that the tongues at least partially warp and against the walls to press.
- the normal force for insertion under compressive stress is greater than the force in a sliding or friction fit, also referred to as holding, in which there is little or no distortion of the tongue.
- a twisted tongue 40 which is similar to the tongue 38 and is formed by rotation of the tongue 38 about the exiting from the outer edge 36 axis 59.
- the axis 59 is substantially aligned with an axis exiting the outer edge 36.
- Fig. 6b shows a tongue 38 before twisting
- Fig. 7b shows a tongue 40 (the tongue 38 after twisting about the axis 59).
- the slot 24 includes axial walls 60 and 62. While the twisted tongue 40 is in the slot 24, the corners 64 and 66 press against the walls 60 and 62, thus supporting the blade 26 within the housing shell 22. The corners 64 and 66 exert a compressive stress on the walls in a substantially circumferential direction with respect to a torque converter into which the bucket is to be installed, thus supporting the bucket 26 within the housing shell 22.
- the protruding tongue 42 is connected to the blade by a transition piece 70 and includes a leg 72 leaving a gap between the leg 72 and the edge 36 ,
- the leg 72 is additionally rotated about an axis (not shown) that exits the edge 36 through the transition piece 70, similar to the formation of the twisted tongue 40. In some aspects, this axis is aligned similar to axis 59.
- the tapered slot 68 includes walls 74 and 76 and an inclined wall 78. The sloping wall 78 provides a means for guiding the protruding tab 42 upon insertion into the slot 68.
- Twisted tongues may also be viewed from the perspective of corresponding planes.
- the blade 26 in Figures 6a-7b includes a body 86 having a surface 88. Generally, tabs project out of the body 86.
- the tongue 40 includes a surface 90. It can be seen from Figure 7b that the surfaces 88 and 90 are offset from each other.
- the blades 26 in the housing shell 22 are supported in the housing shell 22 by the compressive stress of a tongue as an integral part of the blade 26 on the inner walls of a slot, eg, the slot 24 with the walls 60 and 62.
- a slot eg, the slot 24 with the walls 60 and 62.
- the inserted into the slot 24 tongue must be far enough twisted so that one or more corners are coupled by compression with the inner walls.
- the width from one corner of the twisted tongue to the other corner should be greater than the width of the slot.
- other methods (not shown) of forming a tongue and / or slot are also possible.
- the tongue 42 may include a material that extends in two directions from the transition piece 70 and thereby forms a "T", the tongue 38 may be bent instead of twisting, or the slot 68 may have another bevelled wall as part of Wall 76.
- FIG. 10 shows a cross-sectional view of the torque converter impeller shell 122 having slots 124 and the torque converter blade 126 of the torque converter having integral extended portions substantially tangent to the edge 136.
- FIG. 11 is an enlarged cross-sectional view of the portion 11 of FIG. 10 showing the housing shell 122 and a slot 146.
- the blade 126 includes a tongue 128 that is disposed to engage a central ring (not shown).
- the blade 126 includes an elongate tab 152 that is disposed to engage the slot 146. Similar as in the embodiments described above, first the tongue 138 is inserted into the slot 124, and then the extended tongue 152 and then the tongue 154 are pressed and inserted to the slots 146 and 150, respectively.
- the shoulder 156 When the extended tongue 152 is inserted into the slot 146, the shoulder 156 is pressed against the wall 158 and the corner 160 against the wall 162, thereby supporting the blade 126 within the housing shell 122. That is, the length 164 of the tongue 152 is greater than the width 166 of the slot 146 so that the tongue 152 can not fit into the slot without warping and interference fit.
- FIG. 12 shows a cross-sectional view of a second type of torque converter impeller shell 170 having slots 124 and impeller blade 126 of the integrated elongated part converter substantially tangential to the edge 136.
- FIG. 13 is an enlarged cross-sectional view of the cutout 13 of FIG. 12, showing the housing shell 170 and a slot 172.
- the tongue 138 is first inserted into the slot 124, and then the elongated tabs 152 and 174 are pushed and plugged into the slots 146 and 172, respectively.
- the corner 176 is bent by the slope 178 to the side and then presses against the wall 180.
- the distance between the tongues 138, 152 and 174 and the distance between the slots 124, 146 and 172 is sized so that the end 182 protrudes beyond the wall 180 when the tongues 152 engage the slots 146 so that an interference fit between the end 182 and the wall 180 is achieved. That is, the tongue 174 must be compressed to fit within the slot 172.
- the vane 126 may be connected in compression to the housing shells 122 or 170 using the tongue 152, the tongue 174, or using the tongues 152 and 174, and thereby held.
