Abstract
Description
Technical Field
[0001] This utility model relates to SOWC coils, specifically a large-size SOWC coil frame and a SOWC coil using the frame. Background Technology
[0002] For automobiles, the one-way clutch (OWC) is a very small component. The OWC ensures that the motor armature shaft can drive the drive gear, which in turn drives the engine flywheel. Once the engine starts successfully and the flywheel speed increases, exceeding the motor speed, the OWC connection automatically disconnects to prevent damage from motor overspeed. The optional one-way clutch (SOWC) is used in the latest 9AT transmissions to reduce energy loss during clutch churning, allowing for smaller transmission size and weight. The SOWC adds a locking device in the other rotation direction, controlled by a hydraulically controlled slide plate, allowing for reverse locking. The SOWC coil provides the driving force in the optional one-way clutch. Currently, SOWC coils are made using resin injection. This injection method requires significant investment in specialized, high-precision, and high-stability injection equipment and verification of epoxy resin matching processes, resulting in a long development cycle and high initial investment costs in the early stages of product development.

[0032] Example:
[0033] Figure 1 It is a large-size SOWC coil bobbin, including a bobbin body 1; the bobbin body 1 has a first stop 101, a second stop 102, and a winding body 103; the first stop 101 can be connected to the pin 2.
[0034] The first stop 101, the second stop 102, and the winding body 103 form an I-shaped structure, which can be used to wind coils.
[0035] The first stop 101 has an inlet hook 14 on the first side of the connecting pin 2 position for hooking one end of the coil 5, and an outlet hook 15 on the second side for hooking the other end of the coil 5. An inlet auxiliary part 11 is provided on the other side of the inlet hook 14 for smooth inlet, and an outlet auxiliary part 13 is provided on the other side of the outlet hook 15 for smooth outlet. A wire-passing auxiliary part 12 is provided between the inlet auxiliary part 11 and the outlet auxiliary part 13 for guiding the end of the coil 5 from the winding body 103 to the outlet auxiliary part 13.
[0036] This utility model designs a coil frame for large-size SOWC coils. It is equipped with an inlet hook post 14 and an outlet hook post 15 to hook the two ends of the coil and prevent it from retracting. The inlet auxiliary part 11, the through auxiliary part 12, and the outlet auxiliary part 13 are provided to facilitate the appearance of the inlet point when winding the wire, ensuring that the cable of the large-size coil can be well wound on the frame and will not fall off automatically.
[0037] Figure 2 yes Figure 1 The enlarged schematic diagram of section A shows that the first baffle 101 has a platform at one position that can connect to the pin 2, and can also set up the inlet hook 14 and outlet hook 15 as the entry and exit points for cables. Combined with... Figure 1 The cable guide 12 is positioned opposite the platform to facilitate the smooth exit of the cable after it is routed out. Figure 2 It can also be seen that the inlet hook post 14 and the outlet hook post 15 are located on both sides of the platform, serving as the outlet end and the inlet end, respectively.
[0038] Figure 3 yes Figure 1 The first angle diagram shows that the wire entry auxiliary part 11 includes a wire entry groove, specifically including a wire entry groove 111 and a transition groove 114. The wire entry groove 111 and the transition groove 114 are used to introduce the coil 5. The wire entry groove 111 is opened on the side of the first stop 101 and starts from the wire entry hook post 14, gradually shifting towards the winding body 103, and finally the end penetrates through the first stop 101. The transition groove 114 is opened on the inner side of the first stop 101. The starting end of the transition groove 114 is connected to the end of the wire entry groove 111. The end radius of the transition groove 114 gradually decreases and extends to the winding body 103.
[0039] The starting end of the cable inlet groove 111 of this utility model is located in the middle of the side of the first baffle 101, and then gradually shifts downward (in the direction shown in the figure) and gradually passes through the bottom surface of the first baffle 101. This structure facilitates the extension of the cable to the winding body 103, so that the winding can be carried out smoothly. The starting end of the cable inlet groove 111 is located in the middle of the first baffle 101, which can form a wrapping effect on the cable, play a traction and guiding role, and further play a limiting role to prevent the cable from falling off.
[0040] The end radius of the transition groove 114 of this utility model gradually decreases and extends to the winding body 103, which can smoothly guide the cable to the position of the winding body 103 to form the starting state of winding, making it easy to start the winding process quickly.
[0041] The wire entry auxiliary part 11 also includes a wire entry limiting part, specifically including an upper limit block 112 and a lower limit block 113. The upper limit block 112 is located on the upper side of the starting end of the wire entry groove 111, and the lower limit block 113 is located on the lower side of the end of the wire entry groove 111. Both the upper limit block 112 and the lower limit block 113 protrude from the edge of the first stop 101.
[0042] This utility model is equipped with an upper limit block 112 and a lower limit block 113, which increase the limiting range by protruding the two limit blocks to prevent the cable from falling off.
[0043] Figure 4 yes Figure 1 The second angle diagram, Figure 5 yes Figure 4 Enlarged diagram of part B in the middle. Figure 6 yes Figure 4 The side view shows that the wire guide auxiliary part 12 includes a wire guide groove, specifically a wire guide groove 121, which is formed on the side of the first stop 101. The first stop 101 has a notch 123 at a position away from the pin 2. The starting end of the wire guide groove 121 is the notch 123, and the end of the wire guide groove 121 extends towards the position where it appears. The wire guide groove 121 is used to introduce the coil 5.
[0044] The cable guide groove 121 of this invention can receive the cable when the winding is about to end, and the cable is wound from the notch 123 into the cable guide groove 121, gradually extending towards the exit position along the cable guide groove 121. The other side of the notch 123 is set as a slope 124 to adapt to the slope generated by the upward winding of the cable, ensuring that the cable passes smoothly. It can be easily wound from the lower winding body 103 position to the upper cable guide groove 121 position, matching the direction of the cable continuing to wind, and the effect is better.
[0045] The cable tray 121 is located in the middle of the first retaining edge 101 and can wrap the cable to prevent it from coming off.
[0046] The wire guide auxiliary part 12 also includes a wire guide limiting part, specifically including a wire guide limiting block 122. The wire guide limiting block 122 is disposed on the lower side of the starting end of the wire guide groove 121 and protrudes from the edge of the first stop 101.
[0047] The cable guide block 122 of this utility model can play a limiting role from below, preventing the cable from falling into the starting end of the cable guide groove 121. The protruding structure increases the limiting range and improves the effect.
[0048] Figure 7 yes Figure 1 The third angle diagram, Figure 8 yes Figure 7 The enlarged schematic diagram of part C shows that the wire exiting auxiliary part 13 includes a wire exiting groove, specifically a wire exiting groove 131, which is formed on the side of the first stop 101. The starting end of the wire exiting groove 131 extends to the wire passing auxiliary part 12, and the ending end of the wire exiting groove 131 extends to the wire exiting hook post 15. The wire exiting groove 131 is used to introduce the coil 5.
[0049] In this invention, the cable outlet groove 131 and the cable passage groove 121 are the same groove, which facilitates the smooth pulling of the cable.
[0050] The cable outlet groove 131 of this utility model can receive the cable end after winding, and confine the cable end within the cable outlet groove 131, which facilitates fast cable exit and prevents the cable from falling off.
[0051] The cable exiting auxiliary part 13 also includes a cable exiting limiting part, specifically including a cable exiting limiting block 133. The cable exiting limiting block 133 is disposed on the upper side of the end of the cable exiting groove 131, and the cable exiting limiting block 133 protrudes from the edge of the first stop 101.
[0052] The cable exit limit block 133 of this utility model can play a limiting role from above, preventing the cable from coming out of the exit groove when it is hooked upwards. The protruding structure increases the limiting range and improves the effect.
[0053] The cable outlet 131 has a clearance slope 132 on its lower side near the end position, and the clearance slope 132 and the end of the cable outlet 131 form a clearance notch 134.
[0054] Since the cable needs to be pulled down and then pulled up to hook onto the outlet hook post 15 when the winding is finished, the clearance notch 134 is set to facilitate the cable pulling down, and the outlet limit block 133 can prevent the cable from coming off when it is pulled up.
[0055] This invention designs a frame for the SOWC coil, around which the coil is wound, allowing the pin to be mounted, thus facilitating winding. The frame is precisely calculated based on the diameter of the enameled wire, and a toothed arrangement is designed to ensure the stability of subsequent winding. After winding, the pin and enameled wire are fused together to achieve conductivity, and the pin head can also be crimped and soldered to the conductor, satisfying the assembly requirements of the terminal conductor outlet.
[0056] Figure 9 This is a schematic diagram of a large-size SOWC coil, including a frame body 1, a pin 2, and a coil 5. The pin 2 is connected to the first stop 101. One end of the coil 5 is hooked on the wire inlet hook post 14 and introduced into the wire inlet auxiliary part 11. After being wound on the frame body 1, it is introduced into the wire passing auxiliary part 12 and the wire exit auxiliary part 13 in sequence, and finally hooked on the wire exit hook post 15.
[0057] After the cable is wound into a coil, both ends of the coil are connected to pin 2, and then... Figure 2 The pressure plate of pin 2 presses down to tightly connect the two ends of the coil to the pin to prevent poor contact, connects the wire 3 to the pin, and encapsulates the entire skeleton body 1 with a plastic layer 3.
[0058] The cable is made of enameled wire.
[0059] like Figure 3 As shown, the first retaining edge 101 is also provided with a filling groove 16 to enhance the strength between it and the plastic layer 3.
[0060] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way.
