Description
The present invention relates to flywheels for automotive engines, and in particular to dual mass flywheels and methods of centering same during balancing processes.
In the prior art, dual mass flywheels are commonly used in automotive engines to reduce the effect of torsional vibration of the engine crankshaft on the transmission. Fig. 1 shows a schematic cross-sectional view of a half structure of a prior art dual mass flywheel taken along a radial direction R. As shown in the drawing, the dual mass flywheel has a disk shape as a whole and includes a main flywheel 1, a sub flywheel 2, an arc spring 3, a flange plate 4, a distance plate 5, a hub core 6, a cover plate 7, and a fixing member 8.
Specifically, the main flywheel 1 has a disk shape and is provided on one side (left side in the drawing) in the axial direction of the sub flywheel 2, and the main flywheel 1 is fixed to an engine crankshaft so that the main flywheel 1 can be rotated by the engine crankshaft.
The sub flywheel 2 also has a disk shape and the sub flywheel 2 is provided on the other side (right side in the drawing) in the axial direction of the main flywheel 1 at a distance from the main flywheel 1 in the axial direction a.
The two arc springs 3 are accommodated in circumferential grooves formed in the radially outer portion of the main flywheel 1, and the positions of the two arc springs 3 are defined in the axial direction a and the radial direction R by both the cover plate 7 and the main flywheel 1. Each arcuate spring 3 extends in a curved manner in the circumferential direction and each arcuate spring 3 extends over a central angle of approximately 180 degrees in the mounted state. The arc spring 3 can rotate along with the rotation of the main flywheel 1.
The flange plate 4 is located between the main flywheel 1 and the auxiliary flywheel 2 in the axial direction a. The radially outer portion of the flange 4 can abut the circumferential end portions of the two arcuate springs 3. Like this, arc spring 3's circumference tip butt ring flange 4 when arc spring 3 rotates for arc spring 3 drives ring flange 4 and rotates when compressing. The flange plate 4 and the auxiliary flywheel 2 are fixed together, and the flange plate 4 is also provided with a centrifugal pendulum structure.
The distance plate 5 has a disk shape, and the distance plate 5 is provided on the other axial side of the flange plate 4 and fixed to the flange plate 4 by a fixing member (rivet) 8.
The hub core 6 is arranged at the other axial side of the distance plate 5, the hub core 6 is connected with an input shaft of the transmission through a spline arranged in a central hole of the hub core 6, and the radial outer part of the hub core 6 is positioned between the distance plate 5 and the auxiliary flywheel 2 and is fixed with the distance plate 5 and the flange plate 4 through the fixing piece 8. The hub core 6 is also fixed to the sub flywheel 2 (for example, by rivets, not shown).
Thus, the dual mass flywheel having the above-described structure is used to effectively damp torsional vibration of the engine crankshaft. In order to effectively damp the torsional vibration of the crankshaft of the engine, the dual mass flywheel needs to be balanced in advance to eliminate the unbalance of the dual mass flywheel during the rotation process. In general, in the process of performing balance processing on a dual mass flywheel, the dual mass flywheel is placed so that the side where the main flywheel is located faces downward and the side where the sub flywheel is located faces upward; and then inserting the middle alignment shaft with smaller top end size into the central hole of the main flywheel from the side of the main flywheel and further extending to the central hole of the hub core so as to simultaneously support the main flywheel and the hub core and realize the centering of the dual-mass flywheel through the middle alignment shaft. A prerequisite for this centering method is that the diameter of the central hole of the main flywheel is larger than the diameter of the central hole of the hub core (the diameter of the addendum circle of the splines of the hub core).
However, in certain dual mass flywheels (such as the one shown in fig. 1), the diameter of the central bore of the primary flywheel is smaller than the diameter of the central bore of the hub. If the above centering method is still used, the dual mass flywheel needs to be placed in such a way that the side of the primary flywheel faces upward and the side of the secondary flywheel faces downward, which requires the dual mass flywheel to be turned 180 degrees relative to the existing centering method. However, there is no workstation on the existing production line that can perform such a turn-over, and the cost of developing such a workstation is very high and requires a lot of time.

An embodiment of a dual mass flywheel according to the present invention is explained below with reference to the drawings. In the drawings, axial, radial and circumferential refer to the axial, radial and circumferential directions of the dual mass flywheel, respectively, unless otherwise specified; the axially one side refers to the left side of fig. 2a, 3a and 4, and the axially other side refers to the right side of fig. 2a, 3a and 4.
The basic structure of the dual mass flywheel according to the present invention is the same as that of the prior art dual mass flywheel shown in fig. 1, and the difference therebetween is that the structure of the distance plate of the dual mass flywheel according to the present invention is different from that of the prior art dual mass flywheel.
(Structure of Dual Mass flywheel according to first embodiment of the present invention)
As shown in fig. 2a and 2b, the dual mass flywheel according to the first embodiment of the present invention includes a main flywheel 1, an auxiliary flywheel 2, an arc spring 3, a flange plate 4, a distance plate 5, a hub 6, a cover plate 7, and a fixing member 8, as in the dual mass flywheel of the related art shown in fig. 1.
In the present embodiment, the main flywheel 1 and the sub-flywheel 2 are provided at a distance in the axial direction a. The arcuate spring 3 is defined between the main flywheel 1 and the cover plate 7. The flange plate 4, the distance plate 5 and the hub core 6 are arranged in this order from the side where the primary flywheel 1 is located toward the side where the secondary flywheel 2 is located. The flange plate 4 and the distance plate 5 are positioned between the main flywheel 1 and the auxiliary flywheel 2, and the flange plate 4, the distance plate 5 and the hub core 6 are fixed together and fixed on the auxiliary flywheel 2 through fixing pieces (rivets) 8.
Further, a main flywheel center hole 11 is formed in a central portion of the main flywheel 1, a distance plate center hole 51 is formed in a central portion of the distance plate 5, and a hub center hole 61 is formed in a central portion of the hub 6. The center axis of the main freewheel center hole 11, the center axis of the distance plate center hole 51, and the center axis of the hub core center hole 61 coincide such that the main freewheel center hole 11, the distance plate center hole 51, and the hub core center hole 61 are aligned in the axial direction a. Further, the diameter of the main freewheel center hole 11 is smaller than the diameter of the hub core center hole 61 (the diameter of the addendum circle of the spline of the hub core 6), and the diameter of the distance plate center hole 51 is smaller than the diameter of the main freewheel center hole 11.
Further, a plurality of hub through holes 62 through which the coupling member passes are formed in a portion of the hub 6 located radially outward of the hub center hole 61, and a plurality of distance plate through holes 52 through which the coupling member passes are formed in a portion of the distance plate 5 located radially outward of the distance plate center hole 51. The coupling member is, for example, a threaded coupling member for fixing the main flywheel 1 to the engine crankshaft, and a mounting hole of the main flywheel 1 for mounting the coupling member is not shown in the figure. Both the size of the hub through hole 62 and the size of the distance plate through hole 52 are larger than the maximum size of the connector so that the connector can smoothly pass through the hub through hole 62 and the distance plate through hole 52. The distance plate through bore 52 is aligned with the hub through bore 62 in the axial direction a. The plurality of hub through holes 62 are evenly distributed in the circumferential direction and the plurality of distance plate through holes 52 are evenly distributed in the circumferential direction.
The distance plate 5 is also formed with a plurality of distance plate fixing holes 53 through which fixing members 8 for fixing the flange plate 4, the distance plate 5 and the hub 6 pass, and the plurality of distance plate fixing holes 53 are located radially outside the distance plate through-holes 52 and distributed along the circumferential direction.
Thus, in the case of the centering method of the balance process described below, it is possible to center the dual mass flywheel by inserting the centering shaft from the side of the main flywheel 1 and passing through the main flywheel center hole 11 and the spacer plate center hole 51 without turning the dual mass flywheel over.
(Structure of Dual Mass flywheel according to second embodiment of the present invention)
As shown in fig. 3a and 3b, the basic structure of the dual mass flywheel according to the second embodiment of the present invention is the same as that of the dual mass flywheel according to the first embodiment of the present invention, except that the distance plate 5 of the dual mass flywheel according to the second embodiment of the present invention is formed with a flange 54 protruding from the opening peripheral edge of the distance plate center hole 51 toward one side in the axial direction (the side on which the main flywheel 1 is located). In this way, the dimension of the centering shaft in contact with the distance plate center hole 51 can be increased when the centering shaft is located in the distance plate center hole 51.
Having described the structure of the dual mass flywheel according to the present invention, the centering method of the dual mass flywheel according to the present invention during the balancing process will be described below based on the dual mass flywheel according to the first embodiment of the present invention.
(centering method of dual mass flywheel in balance process)
As shown in fig. 4, the centering method according to the invention preferably comprises the following steps:
a centering shaft 9 for centering the dual mass flywheel is inserted into the main flywheel center hole 11 from the side (axial side) of the main flywheel 1 of the dual mass flywheel and extends to the distance plate center hole 51; and
the centering shaft 9 is passed through the main flywheel center hole 11 and the distance plate center hole 51, and the centering shaft 9 is simultaneously matched with the main flywheel center hole 11 and the distance plate center hole 51 to center the dual mass flywheel.
Further, the centering shaft 9 includes a first support portion 91 and a second support portion 92 located at a center hole of the main flywheel 1, which are connected to each other, and the diameter of the first support portion 91 is smaller than that of the second support portion 92. After the centering shaft 9 is inserted into the main flywheel center hole 11 from the side where the main flywheel 1 is located and extends to the distance plate center hole 51, the first support portion 91 is located at the distance plate center hole 51 and supports the distance plate 5 from the radially inner side and the second support portion 92 is located at the main flywheel center hole 11 and supports the main flywheel 1 from the radially inner side.
Thus, even if the diameter of the main flywheel center hole 11 of the dual mass flywheel is smaller than the diameter of the hub core center hole 61, the dual mass flywheel can be centered in a similar manner to the prior art centering method without turning over the dual mass flywheel. That is, the dual mass flywheel may be placed in a manner that the side of the main flywheel 1 faces downward and the side of the auxiliary flywheel 2 faces upward, and then the centering shaft 9 with a smaller tip size is inserted into the main flywheel center hole 11 from the side of the main flywheel 1 and further extends to the distance plate center hole 51, so that the centering shaft 9 is matched with the main flywheel center hole 11 and the distance plate center hole 51 to center the dual mass flywheel.
In addition, although the technical solution of the present invention is explained in detail in the above embodiments, it should be noted that:
1. although not illustrated in the above-described embodiment, it is understood that the radial dimension of the first support part 91 can be slightly enlarged by a necessary mechanical structure after reaching the distance plate center hole 51 so that the first support part 91 can closely abut against the distance plate center hole 51 to support the distance plate 5.
2. Although it has been described in the above-described embodiment that the distance plate 5 of the dual mass flywheel is formed with the flange 54 protruding from the opening peripheral edge of the distance plate center hole 51 toward one side in the axial direction (the side where the primary flywheel 1 is located), the present invention is not limited thereto. If the distance between the distance plate 5 and the hub 6 permits, the distance plate 5 may be formed with a flange that protrudes from the opening peripheral edge of the distance plate center hole 51 toward the other axial side (the side where the sub flywheel 2 is located).
