[0008] Fig. Figure 1A is a schematic side view of an eccentric traction drive 100 for use in a super turbocharger. The eccentric traction drive 100 comprises one or more holding planetary gears 110, 112, a turbo shaft 102, a charging planetary gear 114, an outer ring 116, and a transmission gear 118.

[0009] The turbo shaft 102 is arranged eccentrically in the traction drive 100. The turbo shaft 102 has one or more shaft traction surfaces 108. The retaining planets 110, 112 are supported by a planet carrier (not in Fig. (1 shown) are held in position and have retaining planetary outer pull surfaces 120, 122 which interact with a shaft pull surface 108 of the turbo shaft 102. The interaction of the retaining planetary outer pull surfaces 120, 122 with the shaft pull surface 108 forms shaft-retaining planetary pull interfaces 134, 136, which transmit a torque between the turbo shaft 102 and the retaining planetary devices 110, 112. The charging planetary device 114 is arranged on one side of the turbo shaft 102 substantially opposite the retaining planetary devices 110, 112. The charging planetary device 114 has charging planetary outer pull surfaces 124. The charging planetary outer pull surface 124 interacts with the shaft pull surface 108 to form a shaft-charging planetary pull interface 138. The shaft-charging planetary cross-sectional area 138 transmits a torque between the turbo shaft 102 and the charging planetary 114. The charging planetary 114 is in a planetary carrier (not in Fig. (1 shown) is mounted such that it permits translational movement normal to the axis of rotation of the charging planet 114. The translational movement of the charging planet 114 can be enabled by using a flexible mounting mechanism such as a charging planet tolerance ring 160. Retaining planet tolerance rings 162, 164 can also be used to mount the retaining planets 110, 112, thereby providing damping of the turbo shaft 102. The tolerance rings can be used in a bore for turbocharger mounting parts. The tolerance rings are generally self-retaining and can be designed to fit within a nominal circumference. The tolerance rings 160 provide flexible mounting of the retaining planets 110, 112, as described in U.S. Patent 8,668,614, dated March 11, 2014, entitled “HIGH TORQUE TRACTION DRIVE,” which is incorporated herein in its entirety by reference. The tolerance rings 160 can be mounted on the recessed parts of the bearing (see Fig. 3, in which the bearings are indicated by reference numerals 350, 352). The tolerance rings are specified in various embodiments of the invention with reference to Fig. 3 explained in more detail.

[0010] In a Fig. In the embodiment of the invention shown in Figure 1A, the retaining planets 110, 112 have retaining planet inner pull surfaces 126, 128 whose diameter is smaller than that of the retaining planet outer pull surfaces 120, 122. Similarly, the loading planet 114 has a loading planet inner pull surface 130 whose diameter is smaller than that of the loading planet outer pull surface 124. The retaining planet inner pull surfaces 126, 128 and the loading planet inner pull surface 130 interact with the annular pull surface 132 of the outer ring 116. Through the interaction of the planetary inner pull surfaces 126, 128 and the charging planetary inner pull surface 130 with the ring pull surface 132 of the outer ring 116, holding planetary ring pull cross-sectional surfaces 140, 142 and a charging planetary ring pull cross-sectional surface 144 are formed, which transmit a torque between the holding planets 110, 112, the charging planet 114 and the outer ring 116.

[0011] In one embodiment of the invention, the retaining planetary outer pull surfaces 120, 122 and the charging planetary outer pull surface 124 can interact with the annular pull surface 132 to form retaining planetary annular pull surfaces 140, 142 and a charging planetary annular pull surface 144. Separate planetary inner pull surfaces 126, 128, 130 enable a greater reduction ratio from the turbo shaft 102 to the outer ring 116 in a more compact package. The diameters of the planetary inner pull surfaces 126, 128, 130 are dimensioned such that the reduction ratio from the turbo shaft 102 to the outer ring 116 via the retaining planetary elements 110, 112 is equal to the reduction ratio from the turbo shaft 102 to the outer ring 116 via the charging planetary element 114.

[0012] The outer ring 118 is arranged eccentrically with respect to the turbo shaft 102, so that a wedge gap exists in which the charging planet 114 is arranged. The distance of section AB 150 (as in Fig. 1 shown) between the turbo shaft 102 and the outer ring 116 is greater than the distance of section CD 152 (as shown in Fig. (1 shown) between the turbo shaft 102 and the outer ring 116. When a torque is applied in any direction via the eccentric planetary drive 100, the charging planet 114 undergoes a translational movement from its nominal position, represented by section AB, and moves into a narrower space between the turbo shaft 102 and the outer ring 116, represented by section CD, so that the normal force across all the traction interfaces 134, 136, 138, 140, 142, 144 increases. The direction of the applied torque affects the direction of movement of the charging planet 114. The torque capacity of the tensile cutting surfaces 134, 136, 138, 140, 142, 144 is proportional to the normal force on these cutting surfaces and thus provides a possibility for an increase in the torque capacity of tensile cutting surfaces 134, 136, 138, 140, 142, 144 when the torque requirement increases.The outer ring 116 is connected to a transmission gear 118, which connects the eccentric planetary drive 100 to a motor system (not shown).

[0013] Fig. Figure 1B is a schematic side view of an eccentric traction drive 100 for use in a super turbocharger, showing a translational movement of the charging planet 114. As in Fig. As shown in Figure 1B, the charging planet 114 is pressed into a wedge gap between the turbo shaft 102 and the outer ring 116 when a torque is transmitted via the eccentric planetary drive 100. The movement is exaggerated for clarity. It should be noted that the translational movement of the charging planet 114 is smaller than shown in Figure 1B. Fig. 1B may be shown. As explained above, section CD 152 (in Fig. 1A) The section between the turbo shaft 102 and the outer ring 116 is shorter than section AB 150, so that the charging planet 114 is effectively clamped between the turbo shaft 102 and the outer ring 116, thereby increasing the normal forces across all the tensile surfaces 134, 136, 138, 140, 142, 144. This increase in normal forces increases the torque capacity of all the tensile surfaces 134, 136, 138, 140, 142, 144, so that the torque-carrying capacity of the eccentric planetary drive 100 increases with an increase in torque demand. The tolerance ring 160 can be used to provide flexible mounting of the charging planet 114.

[0014] Fig. Figure 2 is a schematic, isometric view of a single-diameter eccentric planetary drive super turbocharger 200. The eccentric planetary drive super turbocharger 200 comprises at least two holding planets 210, 212, a turbo shaft 202, a charging planet 214, an outer ring 216 and a transmission gear 218.

[0015] One end of the turboshaft 202 is attached to a compressor 204, and the opposite end is attached to a turbine 206. A shaft pulley surface 208 is arranged in a substantially central part of the turboshaft 202. Holding planets 210, 212 are supported by a planet carrier (not shown in Fig. (2 shown) and have retaining planetary pull surfaces 220, 222 on their outer diameters. Retaining planetary pull surfaces 220, 222 interact with the shaft pull surface 208 to form shaft-retaining planetary pull sections 234, 236. The shaft-retaining planetary pull sections 234, 236 transmit a torque between the turboshaft 202 and the retaining planetary gears 210, 212. The charging planetary gear 214 is arranged substantially opposite the retaining planetary gears 210, 212 with respect to the turboshaft 202. The charging planetary gear 214 has a larger outer diameter than the retaining planetary gears 210, 212. The charging planetary gear 214 is in a planetary carrier (not in Fig. (2 shown) is mounted such that it allows translational movement normal to its axis of rotation. This translational movement of the cargo planet 214 can be achieved using a flexible mounting mechanism such as tolerance rings (not shown). Fig. 2 shown) will be made possible.

[0016] The charging planetary tension surface 224 is formed on the outer diameter of the charging planetary 214. The charging planetary tension surface 224 interacts with the shaft tension surface 208 to form a shaft-charging planetary tension interface 238. The shaft-charging planetary tension interface 238 transmits a torque between the turbo shaft 202 and the charging planetary 214. The holding planetary tension surfaces 220, 222 and the charging planetary tension surface 224 interact with the annular tension surface 232 of the outer ring 216 to form holding planetary annular tension interfaces 240, 242 and a charging planetary annular tension interface 244. The holding planetary ring tensile surfaces 240, 242 and the loading planetary ring tensile surface 224 transmit a torque between the holding planetary surfaces 210, 212, the loading planetary surface 214 and the outer ring 216.

[0017] The outer ring 216 is arranged eccentrically, with the outer ring 216 having a different axis of rotation than the turbo shaft 202, so that a wedge gap exists in which the charging planet 214 is arranged. This corresponds in principle to the wedge gap of Fig. 1, which permits movement of the charging planet 214. When a torque is applied in any direction via the eccentric planetary drive turbocharger 200, the charging planet 214 undergoes a translational movement from its nominal position and moves into a narrower space between the turbo shaft 202 and the outer ring 216, so that the normal force across all the traction interfaces 234, 236, 238, 240, 242, 244 increases. The direction of the applied torque affects the direction of the translational movement of the charging planet 214. The torque capacity of the traction interfaces 234, 236, 238, 240, 242, 244 is proportional to the normal force at these interfaces. Essentially, the torque capacity is proportional to the normal force multiplied by a coefficient of friction. Thus, if the normal force increases, the torque capacity also increases.The torque transmission is related to the slip in the traction drive, which depends on the torque exerted on the turbo shaft 202 or the outer ring 216. The slip increases with the torque until the torque capacity is reached. The outer ring 216 is connected to a transmission gear 218, which connects the eccentric planetary traction drive super turbocharger 200 to a motor system (not shown).

[0018] Fig. Figure 3 is a schematic cross-sectional view of a double-roller thrust absorption eccentric planetary drive super turbocharger 300. The double-roller thrust absorption eccentric planetary drive super turbocharger 300 comprises at least two holding planets 310 (the second holding planet is not shown in the cross-section of Figure 3). Fig. 3 shown and corresponds to the stopping planet 212 of Fig. 2), a turbo shaft 302, a charging planet 314, an outer ring 316 and a transmission gear 318. A turbine 306 and a compressor 304 are also shown.

[0019] The turbo shaft 302 has inclined shaft pull surfaces 308, 309, which are inclined in the same but opposite directions. The compressor 304 is attached to one end of the turbo shaft 302, and the turbine 306 is attached to the other end of the turbo shaft 302. The retaining planet 310 is held in position by a planet carrier 315. The retaining planet 310 has inclined retaining planet outer pull surfaces 320, 322, which interact with the inclined shaft pull surfaces 308, 309 to form shaft-retaining planet pull cross-section surfaces 334, 336. The shaft-holding planetary tension surfaces 334, 336 transmit a torque between the turbo shaft 302 and the holding planetary 310. The charging planetary 314 has inclined charging planetary outer tension surfaces 324, 325, which interact with the inclined shaft tension surfaces 308, 309 to form shaft-charging planetary tension surfaces 338, 339.The shaft-loading planetary traction surfaces 338, 339 transmit a torque between the turboshaft 302 and the loading planet 314. The outer diameter of the loading planet 314 is larger than the outer diameter of the holding planet 310. The inclined traction surfaces 308, 309, 320, 322, 324, 325 position the turboshaft 302 axially and absorb thrust forces from the compressor 304 and the turbine 306 as described in U.S. patent application no. 61,906,938, dated November 21, 2013, entitled "Thrust Absorbing Planetary Traction Drive Superturbo," which is incorporated herein in its entirety by reference.

[0020] The charging planet 314 is mounted in the planet carrier 315 by means of bearings 350, 352 such that the charging planet 314 can move in a translational direction normal to its axis of rotation. The outer ring 316 is arranged eccentrically to the turbo shaft 302, so that a wedge gap is present in which the charging planet 314 is arranged. Ring tensile surfaces 332, 333 interact with the retaining planet inner tensile surfaces 326, 328 and with the charging planet inner tensile surfaces 330, 331 to form retaining planet ring tensile cross-sectional surfaces 340, 342 and charging planet ring tensile cross-sectional surfaces 344, 346. The retaining planetary ring tension surfaces 340, 342 and the charging planetary ring tension surfaces 344, 346 transmit a torque between the outer ring 316, the retaining planetary 310 and the charging planetary 314. The outer ring 316 engages with the transmission gear 318, which couples the eccentric planetary pull drive super turbocharger 300 to a motor system.Due to the arrangement of the holding planet 310, the holding planet ring section surface 342 is not oriented at 180 degrees relative to the loading planet ring section surface 346. The holding planets are positioned as shown in . Fig. 1A is shown not diametrically opposite the loading planet 314. Accordingly, the holding planet ring pull surface 342 is arranged above the shown lowest part of the ring pull surface 332.

[0021] The ring pull surfaces 332, 333, the holding planet inner pull surfaces 326, 328 and the loading planet inner pull surfaces 330, 331 can be inclined so that the outer ring 316 axially passes through the loading planet 314 and the holding planets 310 (and the holding planet corresponding to 212 of Fig. 1A). The retaining planetary gear inner pull surfaces 326, 328 have a smaller diameter than the inclined retaining planetary gear outer pull surfaces 320, 322. Similarly, the charging planetary gear inner pull surfaces 330, 331 have a smaller diameter than the inclined charging planetary gear outer pull surfaces 324, 325. The differences in diameter increase the gear reduction ratio from the turbo shaft 302 to the outer ring 316 in a compact package. The diameters of the retaining planetary gear inner pull surfaces 326, 328 and the charging planetary gear inner pull surfaces 330, 331 enable a speed reduction ratio from the turbo shaft 302 to the outer ring 316 via the retaining planetary gear 310 that is equal to the speed reduction ratio from the turbo shaft 302 to the outer ring 316 via the charging planetary gear 314.

[0022] Applying a torque to the turbo shaft 302 or the outer ring 316 causes a translational movement of the charging planet 314 in the wedge gap between the turbo shaft 302 and the outer ring 316. The translational movement is in Fig. Figure 1B shows that the translational movement causes the charging planet 314 to move into a narrower space between the turbo shaft 302 and the outer ring 316. This results in an increase in the normal force on all tensile interfaces 334, 336, 338, 339, 340, 342, 344, 346 of the eccentric planetary drive super turbocharger 300, thereby increasing the torque capacity of all these tensile interfaces 334, 336, 338, 339, 340, 342, 344, 346. Consequently, the eccentric planetary drive super turbocharger 300 automatically adjusts its torque carrying capacity to the torque throughput requirement during various operating conditions of the engine system.

[0023] The tolerance ring 160 allows for flexible mounting of the charging planet 114 as described above with reference to Fig. 1A and Fig. 1B explains this. As in Fig. As shown in Figure 3, the tolerance rings 360 and 362 are mounted within the bearings 350 and 352. The tolerance rings 360 and 362 can absorb vibration effects from unbalanced turned parts or vibration effects caused by the load planet 314. The tolerance rings 360 and 362 allow the bearings 350 and 352 and the load planet 314 to move within the wedge gap as shown in Figure 3. Fig. 1A and Fig. Figure 1B explains the movement. The tolerance rings 360, 362 are radial springs capable of elastic movement in a radial direction. The tolerance rings 360, 362 can be compressed, allowing the loading planet 314 to move in a translational direction. The tolerance rings 360, 362 can be made of any suitable material that permits elastic movement. In one embodiment of the invention, the tolerance rings 360, 362 can be made of spring steel having a corrugated configuration formed into a ring. The corrugated configuration allows the tolerance rings 360, 362 to be compressed with a specific force, which depends on the thickness and elasticity of the spring steel used in the tolerance rings 360, 362.Because the tolerance rings 360, 362 have a corrugated configuration, the tolerance rings 360, 362 can be bent in a radial direction so that the bearings 350, 352 and the loading planet 314 fit into the wedge gap as in . Fig. 1B can be shown bent.

[0024] Fig. Figure 4 is a schematic cross-sectional view of the embodiment of Fig. 3. The eccentric planetary drive super turbocharger 400 comprises a turbo shaft 302, a charging planet 414, a charging planet (part 1) 450, a charging planet (part 2) 452 and a screw 454.

[0025] The two-part loading planet 414 enables the assembly and pre-loading of the draft cutting surfaces 334, 336, 338, 339, 340, 342, 344, 346 of Fig. 3. The function of the eccentric planetary drive super turbocharger 400 is essentially the same as that of the embodiment of the eccentric planetary drive super turbocharger of Fig. 3. In the embodiment of Fig. The two-part loading planet 414 allows for adjustment of the preload at the traction interfaces 334, 336, 338, 339, 340, 342, 344, 346 during assembly. The two-part loading planet 414 also simplifies the assembly of the eccentric planetary traction drive super turbocharger 400. The loading planet 414 is divided into two parts 450 and 452, which are held together by the screw 454. During assembly, the loading planet parts 450 and 452 are fitted together on opposite sides of the outer ring 316. The screw 454 is then tightened to hold the loading planet parts 450 and 452 together. When the screw 454 is tightened, the charging planetary parts 450, 452 contact the outer ring 316 and the turbo shaft 302 with increased force magnitudes, thereby increasing the normal forces over all the tensile cross-sectional surfaces 334, 336, 338, 339, 340, 342, 344, 346.The screw 454 can be tightened to a desired torque, which sets a desired tensile normal force for all the tensile cutting surfaces 334, 336, 338, 339, 340, 342, 344, 346. The tensile cutting surfaces are in . Fig. 4 not shown and can be used to define the tensile cross-sectional areas of Fig. 3. be similar or identical to these.

[0026] Fig. Figure 5 is a schematic cross-sectional view of a variation of the embodiment of Fig. 3. The double roller thrust absorption planetary traction drive super turbocharger 500 additionally includes retaining planetary teeth 564, inner ring teeth 562 and a retaining planetary ring tooth cut surface 560.

[0027] In one embodiment of the eccentric planetary drive super turbocharger 500, additional torque capacity may be required beyond that provided by the retaining planetary ring tensile surfaces 340, 342. The inner ring teeth 562 and the retaining planetary teeth 564 form retaining planetary ring toothed surfaces 560 between each retaining planetary 310 and the outer ring 316. The retaining planetary ring toothed surfaces 560 have substantially the same diameter as the retaining planetary ring tensile surfaces 340, 342. Accordingly, both surfaces act in parallel to transmit a torque between the retaining planetary 310 and the outer ring 316. In this embodiment, the charging planetary 314 has no additional gears, so there is no interference with the translational movement of the charging planetary 314 in the wedge gap (as in Fig. 1A shown) is given to provide a load for the tensile cross-sectional surfaces 334, 336, 338, 339, 340, 342, 344, 346.

[0028] Fig. Figure 6 is a schematic cross-sectional view of the embodiment of Fig. 5. The eccentric planetary drive super turbocharger 600 additionally includes charging planetary teeth 672 and a charging planetary ring tooth surface 670.

[0029] The charging planet teeth 672 engage with the inner ring teeth 562 to form a charging planet ring tooth surface 670. The charging planet ring tooth surface 670 transmits a greater torque between the charging planet 314 and the outer ring 316 than is possible solely via the charging planet ring tension surfaces 344, 346.

[0030] Fig. Figure 7 is a schematic cross-sectional view of an embodiment of a double-roller eccentric planetary drive super turbocharger 700. The eccentric planetary drive super turbocharger 700 comprises holding planets 710, a turbo shaft 702, a charging planet 714, an outer ring 716 and a planet carrier 715.

[0031] The embodiment of Fig. 7 is the embodiment of Fig. 3 similar. The embodiment of Fig. 7 contains no divided planetary traction surfaces. Each planet has two corresponding inclined or angled traction surfaces that interact with the turbo shaft 702 at an outer part and with the outer ring 716 at an inner part. The outer ring 716 contacts each planet at a smaller diameter than the turbo shaft 702, so that a large downward ratio from the turbo shaft 702 to the outer ring 716 can be achieved with a compact packing, while simplifying the shape of the planets.

[0032] The retaining planet 710 is held in position by the planet carrier 715 and has identically but oppositely inclined retaining planetary tension surfaces 720, 722, which are inclined or angled inwards. The turbo shaft 702 has inclined shaft tension surfaces 708, 709, which interact with outer parts of the inclined retaining planetary tension surfaces 720, 722 to form shaft-retaining planetary tension cross-sections 734, 736. The shaft-retaining planetary tension cross-sections transmit a torque between the turbo shaft 702 and the retaining planet 710. The outer ring 716 has annular tension surfaces 732, 733, which interact with inner parts of the inclined retaining planetary tension surfaces 720, 722 to form retaining planetary annular tension cross-sections 740, 742. The retaining planetary ring tensile surfaces 740, 742 transmit a torque between the retaining planetary 710 and the outer ring 716.The inner parts of the inclined retaining planetary traction surfaces 720, 722, which contact the outer ring 716, have a smaller diameter, so that the overall reduction ratio from the turbo shaft 702 to the outer ring 716 is increased. The charging planet 714 has inclined charging planetary traction surfaces 724, 725, which are essentially the same but inclined or angled inwards in opposite directions. The inclined shaft traction surfaces 708, 709 interact with outer parts of the inclined charging planetary traction surfaces 724, 725 to form shaft-charging planetary traction interfaces 738, 739. And the annular traction surfaces 732, 733 interact with inner parts of the inclined charging planetary traction surfaces 724, 725 to form charging planetary annular traction interfaces 744, 746. The outer ring 716 contacts the charging planet 714 at a smaller diameter than the turbo shaft 702, thereby increasing the reduction ratio from the turbo shaft 702 to the outer ring 716.The shaft-charging planetary tension surfaces 738, 739 transmit a torque between the turbo shaft 702 and the charging planetary 714. The charging planetary ring tension surfaces 744, 746 transmit a torque between the charging planetary 714 and the outer ring 716. The shapes of the inclined charging planetary tension surfaces 724, 725 enable the reduction ratio from the turbo shaft 702 to the outer ring 716 via the charging planetary 714 to essentially correspond to the reduction ratio from the turbo shaft 702 to the outer ring 716 via the retaining planetary 710.

[0033] The charging planet 714 has a larger diameter than the charging planet 710 and is arranged in a wedge gap between the turbo shaft 702 and the outer ring 716. The charging planet 714 is mounted in the planet carrier 715 in such a way that it allows for translational movement. This translational movement of the charging planet 714 is the one described in Fig.The translational movement is similar to that shown in Figure 1B. When a torque is applied to the eccentric planetary drive super turbocharger 700, the charging planet 714 moves into the wedge gap and increases the normal forces on all the traction interfaces 734, 736, 738, 739, 740, 742, 744, 746. This increases the torque capacity of the traction interfaces 734, 736, 738, 739, 740, 742, 744, 746 as the torque requirement increases. Furthermore, the inclined traction surfaces 708, 709, 720, 722, 724, 725 position the turbo shaft 702 axially and absorb thrust forces on the turbo shaft 702 as specified in US 9 670 832 B2 entitled “Thrust Absorbing Planetary Traction Drive Superturbo”.
