Description

Technical Field

[0001] This utility model relates to automotive parts, specifically to a connecting assembly of a connecting sleeve and a gasket for connecting an automotive brake disc and a carbon ceramic disc. Background Technology

[0002] With the development of science and technology, and the progress and innovation of technology, automobile products are changing rapidly, which also puts forward higher technical requirements for stamped parts and fasteners. The connecting sleeves and gaskets used for assembling automobile brake discs and carbon ceramic discs also play a decisive role in the safe driving of vehicles.

[0003] In practical use, existing technologies for assembling brake discs and carbon ceramic discs have problems such as the risk of the shims deflecting within the clearance range, causing them to protrude from the carbon ceramic disc and interfere with the brake disc, as well as poor appearance, which affect the safety of vehicle operation.

[0004] Therefore, there is still room for improvement in the existing connection components between brake discs and carbon ceramic discs. Utility Model Content

[0005] The purpose of this utility model is to provide a high-efficiency connecting assembly for connecting automotive brake discs and carbon ceramic discs, consisting of a connecting rod and a gasket. The outer edge of the gasket is reinforced with an R-angle (Radius Angle, meaning a rounded transition) to ensure it is tightly fixed to the connecting rod, thus preventing the gasket from rotating and protruding from the carbon ceramic disc during use, thereby solving the existing technical problems.

[0006] To achieve the above objectives, this utility model provides a connecting component for a carbon ceramic disc. The carbon ceramic disc is an annular plate, and includes a notch for connecting the connecting component. The connecting component includes a connecting sleeve rod disposed in the notch groove and a gasket disposed on the connecting sleeve rod. The gasket has a square through hole for locking the rod. The outer edge of the gasket facing the notch groove opening includes a left arc, a middle arc, and a right arc. The width of the middle arc is equal to the width of the notch groove opening, and the arc of the middle arc is consistent with the arc of the carbon ceramic disc. The connecting sleeve rod includes a gasket engaging portion, which is inserted into the through hole for connecting the rod. The gasket engaging portion is a square including four rounded transition angles. The diameter of the rounded transition angles is between 88% of the side length of the gasket engaging portion multiplied by the square root of 2 and 90% of the side length of the gasket engaging portion multiplied by the square root of 2.

[0007] According to the preferred embodiment of the present invention, the connecting assembly of the carbon ceramic disc includes a connecting sleeve rod further comprising a bolt assembly bore tube, a rectangular plate, and a large-diameter circular plate. The bolt assembly bore tube, the gasket engaging part, the rectangular plate, and the large-diameter circular plate are formed and fixed in one piece. The center of the bolt assembly bore tube, the center of the gasket engaging part, the center of the rectangular plate, and the center of the large-diameter circular plate are concentric. The rectangular plate is used to engage the notch groove.

[0008] According to the preferred embodiment of the present invention, the connecting component for the carbon ceramic disc is a notch on the outer edge of the carbon ceramic disc.

[0009] According to the preferred embodiment of the present invention, the connecting assembly of the carbon ceramic disc is a pipe with an inner through hole, and the bolt assembly bore tube is used to adjust the length and lock the bolt.

[0010] According to the preferred embodiment of the present invention, the connecting assembly of the carbon ceramic disc has an inner through hole in the bolt assembly bore that connects to the inner through hole of the gasket engagement part, the inner through hole of the rectangular plate part, and the inner through hole of the large circular plate part.

[0011] According to the preferred embodiment of the present invention, the connecting assembly of the carbon ceramic disc has a side length of 9.55mm-9.60mm for the gasket engagement portion and a diameter of 11.88mm-12.21mm for the arc transition angle.

[0012] The design concept of this application is to design a structure in which the gasket will not protrude from the carbon ceramic disc when it deflects within the gap range. The outer edge of the gasket is increased with an R-angle to prevent the carbon ceramic disc from protruding from the gasket when it deflects. The connection between the connecting rod and the gasket has a reduced arc length and an increased contact surface, thereby reducing the allowable gap, making the deflection angle of the gasket smaller, improving vehicle driving safety, reducing risks, and increasing corporate profits.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] First, the gasket in this application will not protrude from the carbon ceramic disc even when it deflects within the gap range;

[0015] Secondly, this application is applicable to both manual and automated assembly. By reducing the arc length of the connection between the connecting rod and the washer and increasing the contact surface, it improves enterprise efficiency.

[0016] This reduces driving risks.

[0017] Of course, implementing any specific embodiment of the content of this application does not necessarily have all of the above technical effects at the same time. Attached Figure Description

[0021] Figure 4 for Figure 3 A left-side view diagram. Detailed Implementation

[0022] The present invention will be described in detail below with reference to the accompanying drawings.

[0023] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The connecting component of this application is used to lock the brake disc and the carbon ceramic disc together, fixing them as a single unit for use in vehicle braking. In the prior art, the gasket used in the application has a risk of the carbon ceramic disc being exposed when it deflects within the gap range due to the gap between the parts, which will affect the safety of vehicle driving. This application adds an R-angle to the outer edge of the gasket so that the outer edge of the gasket extends inward instead of conforming to the arc of the carbon ceramic disc, thus avoiding the exposure of the carbon ceramic disc when the gasket deflects and ensuring driving safety. This design can improve assembly efficiency, is reliable in structure, and is easy to use, and is suitable for both manual and automated assembly.

[0024] Figure 2 In this application, the carbon ceramic disc 10 is an annular sheet, specifically a circular sheet with a diameter of 231.70mm-232.00mm. The carbon ceramic disc 10 includes a notch 11 for connecting the connecting assembly. In this embodiment, the notch 11 of the carbon ceramic disc 10 is a notch on the outer edge of the circumference of the carbon ceramic disc 10. The number of notches 11 is 10, but this cannot be used to limit this application. Any number that can provide stable support should be within the scope of protection of this application. The connecting assembly includes a connecting sleeve 21 disposed in the notch 11 and a gasket 22 disposed on the connecting sleeve 21. Figure 1As shown, the gasket 22 has a square through hole 221 for the locking rod. The outer edge of the gasket 22 facing the notch 11 includes a left arc 222, a middle arc 223, and a right arc 224. In the prior art, the arc of the outer edge of the gasket 22 facing the notch 11 is consistent with the arc of the carbon ceramic disk 10. After assembly, the outer edge of the gasket 22 facing the notch 11 is parallel to the outer edge of the carbon ceramic disk 10. However, after use, there is a risk that the outer edges of the gasket 22 on both sides may deflect and bulge. In this application, the middle arc 223... The width is equal to the width of the notch 11. The arc of the middle arc 223 is consistent with the arc of the carbon ceramic disc 10. In this application, the outer edge of the gasket 22 facing the notch 11 is designed as a three-segment arc of the left arc 222, the middle arc 223, and the right arc 224. In this embodiment, the diameter of the middle arc 223 is the same as the diameter of the carbon ceramic disc 10, which is 231.70mm-232.00mm, while the radii of the left arc 222 and the right arc 224 are both 29.70mm-30.00mm. Figure 1 As shown, the extension directions of the left arc 222 and the right arc 224 are inward, and they will not protrude from the outer edge of the carbon ceramic disk 10 when deflected.

[0025] Please refer to Figure 3 and Figure 4 The connecting sleeve 21 includes a gasket engaging portion 212, which is inserted into the connecting rod through hole 221. The gasket engaging portion 212 is a square including four rounded transition angles 2121. Figure 4 Due to the proportional relationship, the four arc transition angles 2121 appear to be straight lines, but they are actually arc transition lines. The diameter of the arc transition angles 2121 is between 88% of the side length of the gasket engagement portion 212 multiplied by the square root of 2 and 90% of the side length of the gasket engagement portion 212 multiplied by the square root of 2. In this embodiment, the side length of the gasket engagement portion 212 is 9.55mm–9.60mm, and the diameter of the arc transition angles 2121 is 11.88mm–12.21mm.

[0026] like Figure 3As shown, the connecting sleeve 21 also includes a bolt assembly bore tube 211, a rectangular plate 213, and a large-diameter circular plate 214. The bolt assembly bore tube 211, gasket engaging part 212, rectangular plate 213, and large-diameter circular plate 214 are formed and fixed in one piece. The centers of the bolt assembly bore tube 211, gasket engaging part 212, rectangular plate 213, and large-diameter circular plate 214 are concentric, meaning they are on the same straight line. The rectangular plate 213 is used to engage the notch 11, and its rectangular shape allows it to fit the carbon ceramic disc 1. The parallel opposite sides of the notch 11 of the 0 facilitate the insertion of the connecting sleeve 21 into the notch 11 during the locking process of the brake disc and the carbon ceramic disc 10. In addition, the design of the large-cut circular piece 214 can increase the locking strength of the brake disc and the carbon ceramic disc 10. The so-called large-cut circle is the part larger than a semicircle left after cutting a circle. The cut-off part corresponds to the radial outer edge of the carbon ceramic disc 10, so it will not protrude from the outer edge of the carbon ceramic disc 10, causing interference or poor appearance. The large-cut circular piece 214 is stuck on the upper surface of the notch 11 so that the connecting sleeve 21 can lock the brake disc and the carbon ceramic disc 10.

[0027] Figure 3 In this embodiment, the bolt assembly bore tube 211 is a pipe including an inner through hole. The bolt assembly bore tube 211 is used to adjust the length for bolt tightening. Adjusting the length means adjusting the length of the bolt assembly bore tube 211 to accommodate different thicknesses of the brake disc and the carbon ceramic disc 10. The inner through hole of the bolt assembly bore tube 211 connects to the inner through holes of the gasket engagement part 212, the rectangular plate part 213, and the large-diameter circular plate part 214 for bolt passage. The inner through hole of the bolt assembly bore tube 211 is a continuation of the inner through holes of the gasket engagement part 212, the rectangular plate part 213, and the large-diameter circular plate part 214. In this embodiment, during assembly, the brake disc abuts against the carbon ceramic disc 10, and the connecting sleeve 21 penetrates both the brake disc and the carbon ceramic disc 10. The bolt... Figure 3 The left side of the bolt assembly hole tube 211, gasket engagement part 212, rectangular plate part 213 and large round plate part 214 are then tightened with nuts to lock the brake disc and the carbon ceramic disc 10 into a single unit for subsequent assembly onto the vehicle.
