Description

Technical Field

[0001] This utility model belongs to the field of automotive component technology, specifically relating to a shock-absorbing automotive driven disc. Background Technology

[0002] According to the technical solution of the driven plate of a shock-absorbing automotive clutch disclosed in CN218863130U, it mainly includes a driven plate body 2, a friction plate 3 and a driven plate hub 4. The outer surface of the driven plate body 2 is provided with a groove 7, and a retaining plate 8 is installed inside the groove 7. The friction plate 3 is connected to the front surface of the retaining plate 8. The rear surface of the driven plate body 2 is provided with a threaded countersunk hole 9, and a bolt 10 is inserted into the threaded countersunk hole 9. The retaining plate 8 and the driven plate body 2 are connected by the bolt 10.

[0003] This patented solution improves upon the inconvenience of replacing friction plates and the excessive use of rivet consumables in traditional driven discs. However, the following problems still exist in practical applications: 1. Using eight bolts to fix the friction plates does not significantly reduce the number of fastening consumables compared to using rivets; 2. Replacing each friction plate requires disassembling the corresponding bolts, which is still time-consuming and labor-intensive, affecting maintenance efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a shock-absorbing automotive driven disc, which fixes the card plate and friction plate in the card slot by the engagement of the positioning rod and the positioning hole. At the same time, the position of the annular plate and the positioning rod is fixed by the screw connection of the extension plate and the preset hole of the slot. This not only reduces the original 8 fixing bolts to a maximum of 3, reducing material waste, but also allows for the unified disassembly and assembly of all card plates and friction plates by the disassembly of the annular plate, saving time and effort and improving maintenance efficiency.

[0005] The specific technical solution adopted by this utility model is as follows: A shock-absorbing automotive driven disc includes a driven disc body and a retaining plate. The side wall of the driven disc body is provided with an annular groove, and an annular plate is movably embedded in the annular groove. An extension plate is uniformly fixed to the edge of the annular plate in a circumferential direction. The number of extension plates is up to three, and the extension plates are detachably connected to the driven disc body by a threaded fastening mechanism. The annular plate has several positioning rods uniformly fixed to its sidewalls, and several through holes uniformly penetrate the annular groove. A positioning hole is provided on one side of the clamping plate, and the positioning rods are fitted into the positioning hole after passing through the through holes.

[0006] The threaded fastening mechanism includes: a through hole located in the middle of the extension plate, and the annular groove having uniformly distributed grooves on its circumferential edge that correspond to and match the extension plate.

[0007] The groove is also provided with a preset hole corresponding to the insertion hole, and the insertion hole is threadedly connected to the preset hole by a fastening bolt.

[0008] The annular plate has through slots located between the two positioning rods.

[0009] The groove is provided with symmetrical pads on both sides, and the pads are located on the same side as the positioning rod.

[0010] The number of perforations matches the number of positioning rods and their positions correspond. The driven disk body has several slots evenly distributed around its circumference on the side opposite to the annular groove, and the retaining plate is movably installed inside the slots.

[0011] A friction plate is fixedly installed on one side of the card plate.

[0012] The technical advantages achieved by this utility model are as follows: by fitting the positioning rod and the positioning hole, the card plate and friction plate are fixed in the card slot. At the same time, by screwing the extension plate and the preset hole of the slot, the position of the annular plate and the positioning rod is fixed. This not only reduces the original 8 fixing bolts to a maximum of 3, reducing material loss, but also allows for the unified disassembly and assembly of all card plates and friction plates by disassembling the annular plate, saving time and effort and improving maintenance efficiency.

Detailed Implementation

[0015] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0016] This utility model provides a shock-absorbing automotive driven disc, based on the structure of patent CN218863130U, mainly improving the rear surface of the driven disc body 2 and the clamping plate 3; the structure of the components other than the rear surface of the driven disc body and the clamping plate in the original patent remains unchanged, and the specific structure can be found in the embodiment of the original patent.

[0017] The improvements of this utility model include: like Figures 1-3 As shown, a shock-absorbing automotive driven disc includes a driven disc body 2 and a retaining plate 3. The driven disc body 2 has a plurality of retaining grooves 204 evenly arranged circumferentially on the side opposite to the annular groove 201. The retaining plate 3 is movably installed inside the retaining grooves 204. A friction plate 302 is fixedly installed on one side of the retaining plate 3. An extension plate 101 is evenly fixedly connected to the edge of the annular plate 1 circumferentially, and the extension plate 101 is detachably connected to the driven disc body 2 through a threaded fastening mechanism. The number of extension plates 101 is at most three. The threaded fastening mechanism includes: an embedded hole 102 penetrating the middle of the extension plate 101; an embedded groove 203 corresponding to the extension plate 101 is evenly arranged circumferentially on the edge of the annular groove 201; a preset hole corresponding to the embedded hole 102 is also provided in the embedded groove 203; the embedded hole 102 is threadedly connected to the preset hole through a fastening bolt 103.

[0018] According to the above structure, the installation and insertion of the card plate 3 and the card slot 204, as well as the structure of the front surface of the driven disk body 2, are the same as the original patent structure and method. When it is necessary to disassemble the card plate 3 and the friction plate 302, the fastening bolt 103 is removed by rotating it, so that it is separated from the preset hole in the groove 203. The slot 105 is convenient for tools or fingers to be inserted, and the annular plate 1 can be removed from the annular groove 201 more conveniently, and the extension plate 101 is also removed from the groove 203.

[0019] See attached document Figures 2-5 A positioning hole 301 is provided on one side of the card plate 3. The positioning rod 104 passes through the through hole 202 and is fitted into the positioning hole 301. An annular groove 201 is provided on the side wall of the driven plate body 2. An annular plate 1 is movably embedded in the annular groove 201. Several positioning rods 104 are uniformly fixed on the side wall of the annular plate 1. A through groove 105 is provided through the plate body of the annular plate 1 between two positioning rods 104. A pad post 106 is symmetrically provided on both sides of the through groove 105, and the pad post 106 is located on the same side as the positioning rod 104. Several through holes 202 are uniformly passed through the annular groove 201. The number of through holes 202 matches the number and position of the positioning rods 104.

[0020] According to the above structure, as the annular plate 1 disengages from the annular groove 201, along with several positioning rods 104 on its sidewall, it also disengages from the originally fitted positioning holes 301 and through holes 202 and is removed. The retaining plate 3 can then be pulled out from the retaining groove 204. When the annular plate 1 is embedded in the annular groove 201, the pad 106 fits against the annular groove 201, providing rigid support to the area near the through groove 105 and improving the structural stability. Similarly, after the friction plate 302 is replaced, the retaining plate 3 is inserted into the retaining groove 204, and the extension plate 101 is aligned with the groove 203 so that the annular plate 1 is embedded in the annular groove 201. The positioning rods 104 pass through the through holes 202 and fit into the positioning holes 301. Finally, the fastening bolts 103 are tightened to complete the reassembly.

[0021] The working principle of this utility model is as follows: the installation and insertion of the card plate 3 and the card slot 204, as well as the structure of the front surface of the driven disk body 2, are the same as the original patent structure and method. When it is necessary to disassemble the card plate 3 and the friction plate 302, the fastening bolt 103 is removed by rotating it to separate it from the preset hole in the groove 203. By inserting the finger or a screwdriver or other tools into the through slot 105, the annular plate 1 can be removed from the annular groove 201 more conveniently, and the extension plate 101 can also be removed from the groove 203. Furthermore, as the annular plate 1 disengages from the annular groove 201, along with several positioning rods 104 (depending on the number of clamping plates 3) on its sidewalls, they also disengage from the originally fitted positioning holes 301 and through holes 202 and are removed. Without the insertion and fixation of the positioning rods 104, the clamping plates 3 can be pulled out from the groove 204. When the annular plate 1 is embedded in the annular groove 201, the pad 106 fits against the annular groove 201, which can provide rigid support for the area near the through groove 105 and improve the structural stability. Furthermore, after the friction plate 302 is replaced, insert the card plate 3 into the card slot 204, then align the extension plate 101 with the groove 203, so that the annular plate 1 is embedded in the annular groove 201, the positioning rod 104 passes through the through hole 202 and engages with the positioning hole 301, and finally tighten the fastening bolt 103 to complete the reassembly.

[0022] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
