Description

Technical Field

[0001] This utility model relates to the field of vehicle brake technology, specifically to a rubber seal anti-detachment structure for disc brakes. Background Technology

[0002] The disc brake includes a brake caliper body, a pair of push discs, a dust cover, and a screw seal cover. The dust cover is fixed to the cavity of the brake caliper body. A pair of rod holes are opened on the dust cover for the push discs to pass through. The screw seal cover is fixed in the rod holes of the dust cover. Then the push rod of the push disc passes through the screw seal cover. The screw seal cover is used to improve the sealing between the push disc and the dust cover.

[0003] Because most existing screw seal covers are installed into the base plate for waterproofing and sealing by pressing, complete insertion cannot be guaranteed. Furthermore, rubber is elastic, and deformation inevitably occurs during initial insertion. After aging treatment, this deformation releases, creating gaps and contributing to detachment. In addition, cars often encounter muddy or potholed roads after rain. After prolonged downhill driving, the high temperatures of the brake pads or prolonged use can cause the rubber to lose elasticity, altering the tightness between the brake pads and the dust cover, increasing the risk of detachment. This can lead to water ingress and rust in the brakes, significantly impacting their performance. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a structure to prevent the rubber seal of a disc brake from falling off, thereby solving the technical problem that the rubber seal of the previous disc brake was not firmly installed on the base plate and was easy to fall off.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A structure for preventing the rubber seal from detaching in a disc brake is provided, including:

[0007] Dustproof panel, with rod holes opened on the panel body;

[0008] The sealing cover includes an inner sealing element, an outer sealing element, and an elastic folding element. The outer sealing element has an outer step formed on its outside. The outer sealing element is assembled into the rod hole via the outer step. A sealing structure is formed between the outer sealing element and the dustproof plate. The inner sealing element forms a sealing fit with the push plate of the brake.

[0009] A pressure ring is pressed onto the outer seal and is fixedly connected to the dustproof plate, thereby fixing the inner seal to the rod hole of the dustproof plate through the pressure ring.

[0010] Furthermore, the edge of the pressure ring forms multiple connecting edges, and connecting holes are opened on the connecting edges. Screws pass through the connecting holes and the dustproof plate to fix the pressure ring to the dustproof plate.

[0011] Furthermore, a stepped structure is formed between each connecting edge and the pressure ring.

[0012] Furthermore, at least three spot welds are provided between the pressure ring and the dustproof plate to fix the pressure ring to the dustproof plate.

[0013] Furthermore, the edge of the pressure ring forms a downward flange, and a spot weld is provided between the flange and the dustproof plate.

[0014] Furthermore, the outer wall surface of the outer seal that mates with the rod hole has a wavy structure.

[0015] The beneficial effects of this utility model are:

[0016] The disc brake of this utility model has a rubber seal anti-detachment structure. The sealing cover is fixed to the dustproof plate by welding or screwing the pressure ring to the dustproof plate, which prevents the sealing cover from falling off due to high temperature.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] This application provides a rubber seal anti-disengagement structure for disc brakes, which will be described in detail below. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments of this application. Furthermore, in the following embodiments, the descriptions of each embodiment have their own emphasis; parts not described in detail in a certain embodiment can be referred to in the relevant descriptions of other embodiments.

[0030] To address the technical problem of unstable installation of rubber seals on the base plate in existing disc brakes, leading to easy detachment, an embodiment of this application provides an anti-detachment structure for rubber seals in disc brakes. This is described in detail below.

[0031] like Figure 1 , Figure 2 and Figure 5 As shown, a rubber seal anti-disengagement structure for a disc brake includes...

[0032] Dustproof plate 1, with rod holes opened on its body;

[0033] The sealing cover 2 includes an inner sealing element 21, an outer sealing element 22, and an elastic folding element 23. The outer sealing element 22 has an outer step formed on its outside. The outer sealing element 22 is assembled into the rod hole through the outer step. A sealing structure is formed between the outer sealing element 22 and the dustproof plate 1. The inner sealing element 21 forms a sealing fit with the push plate 41 of the brake.

[0034] The pressure ring 3 is pressed onto the outer seal 22 and is fixedly connected to the dustproof plate 1, thereby fixing the inner seal 21 to the rod hole of the dustproof plate 1 through the pressure ring 3.

[0035] like Figure 5 As shown, both the inner seal 21 and the outer seal 22 are provided with metal parts, which are L-shaped structures. The inner seal 21, the outer seal 22 and the elastic folding part 23 are all rubber parts. The entire sealing cover 2 is integrally formed by rubber casting.

[0036] Specifically, as an optional implementation method in this embodiment, such as Figure 1 and Figure 2As shown, the edge of the pressure ring 3 forms multiple connecting edges 31, and connecting holes are opened on the connecting edges 31. Screws 11 pass through the connecting holes and the dustproof plate 1 to fix the pressure ring 3 to the dustproof plate 1.

[0037] In this embodiment, the number of connecting edges 31 is four.

[0038] In this embodiment, a stepped structure is formed between each connecting edge 31 and the pressure ring 3. This stepped structure can be adapted to the sealing cover 2 because the upper end of the outer sealing element 22 of the sealing cover 2 is exposed on the dustproof plate 1, and the exposed part can be located directly below the pressure ring 3.

[0039] In this embodiment, the connecting edge 31 and the pressure ring 3 are an integral structure, and the structure between the pressure ring 3 and the connecting edge 31 is formed by stamping.

[0040] Specifically, as an optional implementation method in this embodiment, such as Figure 5 As shown, the outer wall surface of the outer seal 22 that mates with the rod hole is a corrugated surface 221. The corrugated surface 221 is used to improve the sealing between the outer seal 22 and the rod hole and prevent the outer seal 22 from loosening in the rod hole.

[0041] like Figure 6 The disc brake shown has a dustproof plate 1 installed in the cavity of the brake caliper body 4. Two rod holes are formed in the dustproof plate 1, and two pusher discs 41 move back and forth within the cavity of the brake caliper body 4. The front ends of the pusher discs 41 extend from the dustproof plate 1. The aforementioned rubber sealing anti-detachment structure is installed in the two rod holes of the dustproof plate 1. The sealing cover 2 is now fixed by a pressure ring 3 to reduce gaps caused by deformation and release after aging treatment or high temperature, preventing the sealing cover 2 from falling off.

[0042] Another embodiment of this application provides a rubber seal anti-disengagement structure for a disc brake. This is described in detail below.

[0043] This embodiment is based on the above embodiment, the difference being that the connection method between the pressure ring 3 and the dustproof plate 1 has been changed, such as... Figure 3 , Figure 4 as well as Figure 5 As shown, at least three spot welds (not shown in the figure) are provided between the pressure ring 3 and the dustproof plate 1, and the pressure ring 3 is fixed to the dustproof plate 1 by spot welding.

[0044] Specifically, as an optional implementation method in this embodiment, such as Figure 3 and Figure 4 As shown, the edge of the pressure ring 3 forms a downward flange 32, and a spot weld is provided between the flange 32 and the dustproof plate 1.

[0045] Compared to the screw 11 connection, this fixing method is more convenient, faster, and cheaper, making it suitable for brakes where the seal cover 2 does not need to be replaced. The screw 11 connection is a detachable structure, allowing for later replacement of the seal cover 2.

[0046] All the devices selected in this application (parts whose specific structures are not specified) are general standard parts or parts known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.
