Description

Technical Field

[0001] This utility model relates to the field of precision parts technology, specifically to a precision stretching gasket structure. Background Technology

[0002] In the automotive manufacturing industry, the requirements for assembly precision between various automotive components are increasing day by day. As a basic component that ensures the sealing performance and reasonable gaps between key assemblies such as automotive engines and brakes, gaskets need to maintain the spacing between components, ensure sealing performance, and evenly distribute stress.

[0003] Existing precision stretch-formed ordinary gaskets are prone to dimensional shrinkage and deformation under the high temperature and vibration environment of the braking system, resulting in changes in gasket thickness or uneven surface. This leads to uneven adhesion and stress between the brake pads and the gaskets on the brake disc, resulting in unstable braking performance and affecting driving safety. Utility Model Content

[0004] This invention provides a precision stretching gasket structure that has the advantages of resisting brake thermal fatigue and uneven adhesion between the gasket and brake pad, thus solving the problem that existing gaskets are prone to shrinkage and deformation due to heat, resulting in poor adhesion and braking effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a precision tensioning gasket structure, comprising a gasket body and a brake disc disposed on one side of the gasket body, and further comprising a positioning reinforcement component, a sealing component, and a reinforced edge locking component, wherein:

[0006] The gasket body includes a base layer, the outer side of which is a heat insulation layer, and the outer side of which is a protective outer layer;

[0007] The base layer is made of nickel-based alloy, the heat insulation layer is made of aerogel felt, and the protective outer layer is made of glass fiber reinforced nylon.

[0008] The positioning reinforcement component includes a reinforcing rib with a trapezoidal cross-section. The upper base of the reinforcing rib faces the outside of the pad body, and the lower base is connected to the pad body. The pad body has an inner positioning hole at its center. The inner positioning hole is a conical hole with spiral fine lines on its surface.

[0009] As a preferred embodiment of this utility model, the outer side of the concentrically nested inner positioning hole is provided with a positioning groove, and the positioning groove is a regular polygon.

[0010] As a preferred embodiment of the present invention, the sealing assembly includes a raised sealing ring, which is connected to the gasket body. The sealing ring has a three-stage stepped gradient, with a concave circular groove at the transition of each step.

[0011] As a preferred technical solution of this utility model, the reinforced edge locking assembly includes a locking disc, which is connected to the outer edge of the reinforcing rib, and the surface of the locking disc is provided with wavy peaks and depressions.

[0012] As a preferred technical solution of this utility model, the convex peak extends outward to form a claw, and two layers of rubber discs are fixed at the center of the brake disc. The rubber discs are arranged concentrically, with the upper layer being smaller than the lower layer.

[0013] As a preferred technical solution of this utility model, a positioning block is provided above the rubber disc, the positioning block is fitted with the positioning groove, the rubber disc is fitted with the circular groove, and a conical head is provided above the positioning block, the conical head is fitted with the inner positioning hole and screwed together.

[0014] As a preferred embodiment of this utility model, the rubber disc has an installation edge on its outer side, a rubber filler strip on the top surface of the installation edge, the rubber filler strip being fitted into the recess, and an installation hole on one side of the rubber filler strip being fitted into and locked with the claw.

[0015] Compared with the prior art, this utility model provides a precision tensioned gasket structure with the following advantages: The base layer of the gasket body is made of nickel-based alloy material, which can maintain high strength and good toughness at high temperatures, resist thermal fatigue, effectively cope with the frictional heat generated by the brake disc during braking, and prevent the gasket from shrinking and deforming, thus affecting the braking effect. The aerogel felt material of the heat insulation layer has an ultra-low thermal conductivity, which can block the heat source from spreading to the surrounding area and reduce the impact of thermal shock on the gasket. This structure ensures high precision in the installation position of the gasket body through dual positioning, avoiding uneven contact between the gasket body and the brake pad during braking, which would affect the braking effect. The trapezoidal structure of the reinforcing ribs on the gasket body can effectively disperse the external pressure of the gasket during braking, preventing the edges of the gasket body from turning outward and deforming when under pressure.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0022] Please see Figures 1-4 This utility model discloses a precision tensioning gasket structure, including a gasket body 1 and a brake disc 2 disposed on one side of the gasket body 1, and also includes a positioning reinforcement component 3, a sealing component 4, and a reinforced edge locking component 5, wherein:

[0023] The gasket body 1 includes a base layer 11, an insulation layer 12 on the outside of the base layer 11, and a protective outer layer 13 on the outside of the insulation layer 12;

[0024] Please refer to the appendix. Figure 2 The base layer 11 is made of nickel-based alloy, the heat insulation layer 12 is made of aerogel felt, and the protective outer layer 13 is made of glass fiber reinforced nylon. Specifically, the nickel-based alloy material effectively copes with the frictional heat generated by the brake disc during braking, and prevents the disc from shrinking and deforming, which would affect the braking effect. The aerogel felt material reduces the impact of brake thermal shock on the pads, and the glass fiber reinforced nylon material can reduce pad wear and improve service life.

[0025] Please refer to the appendix. Figure 3 The positioning reinforcement component 3 includes a reinforcing rib 31. The reinforcing rib 31 has a trapezoidal cross section, with its upper bottom facing the outside of the gasket body 1 and its lower bottom connected to the gasket body 1. The gasket body 1 has an inner positioning hole 32 at its center. The inner positioning hole 32 is a conical hole with spiral fine lines on its surface.

[0026] The inner positioning hole 32 is concentrically nested on the outer side and a positioning groove 33 is provided. The positioning groove 33 is a regular polygon.

[0027] In this embodiment, the inner positioning hole 32 of the gasket body 1 forms a precise point contact with the conical head 23 on the brake disc 2 through spiral fine lines, achieving initial rapid positioning. Subsequently, the positioning block 22 and the positioning groove 33 are perfectly matched to achieve secondary angle calibration, thus doubly ensuring the high precision of the gasket body 1 installation position. Example 2

[0028] Based on the above embodiment 1, please refer to the appendix. Figure 3 as well as Figure 4 The sealing assembly 4 includes a raised sealing ring 41, which is connected to the gasket body 1. The sealing ring 41 has a three-step gradient, and each step transition is provided with a concave circular groove 42.

[0029] The reinforced edge locking assembly 5 includes a locking disc 51, which is connected to the outer edge of the reinforcing rib 31. The surface of the locking disc 51 is provided with wavy peaks 52 and recesses 53.

[0030] The protrusion 52 extends outward to form a claw 54. Two layers of rubber discs 21 are fixed at the center of the brake disc 2. The rubber discs 21 are concentrically arranged, with the upper layer being smaller than the lower layer.

[0031] A positioning block 22 is provided above the rubber disc 21. The positioning block 22 is fitted into the positioning groove 33. The rubber disc 21 is fitted into the circular groove 42. A conical head 23 is provided above the positioning block 22. The conical head 23 is fitted into the inner positioning hole 32 and is screwed together. Specifically, the fitting of the rubber disc 21 into the circular groove 42 not only strengthens the sealing contact and increases the stability of the connection between the gasket body 1 and the brake disc 2, but also avoids stress concentration.

[0032] The rubber disc 21 has an installation edge 24 on its outer side, and a rubber filler strip 25 on the top surface of the installation edge 24. The rubber filler strip 25 fits into the recess 53, and an installation hole 26 is provided on one side of the rubber filler strip 25. The installation hole 26 fits into the claw 54 and is locked in place.

[0033] In this embodiment, the claw 54, through the fitting mounting hole 26, prevents the pad body 1 from being displaced by the lateral friction force generated by braking, and the elastic fitting between the recess 53 and the rubber filler strip 25 buffers the impact force received by the pad body 1 during braking.

[0034] The working principle and usage process of this utility model are as follows: First, the base layer 11 of the gasket body 1 is made of nickel-based alloy material, which can maintain high strength and good toughness at high temperature, resist thermal fatigue, effectively cope with the frictional heat generated by the brake disc during braking, and prevent the gasket disc from shrinking and deforming, thus affecting the braking effect. The aerogel felt material of the heat insulation layer 12 has an ultra-low thermal conductivity, which can block the heat source from spreading to the surrounding area and reduce the impact of thermal shock on the gasket. The glass fiber reinforced nylon material of the protective outer layer 13 has high strength and wear-resistant properties, which can reduce the wear of the gasket and improve its service life.

[0035] The inner positioning hole 32 on the gasket body 1 forms a precise point contact with the conical head 23 on the brake disc 2 through spiral fine lines, achieving initial rapid positioning. Subsequently, the positioning block 22 and the positioning groove 33 are perfectly matched to achieve secondary angle calibration, doubly ensuring the high precision of the gasket body 1 installation position and avoiding uneven contact between the gasket body 1 and the brake pad during braking, which would affect the braking effect. The trapezoidal structure of the reinforcing rib 31 on the gasket body 1 can effectively disperse the external pressure of the gasket during braking, preventing the edges of the gasket body 1 from turning outward and deforming when under pressure.

[0036] During positioning, the sealing ring 41 on the gasket body 1 is fitted with the rubber disc 21 of the brake disc 2 through the circular groove 42, which not only strengthens the sealing contact and increases the stability of the connection, but also avoids stress concentration. The protrusion 52 of the locking disc 51 is fitted with the mounting hole 26 through the claw 54 to prevent the gasket from being displaced by the lateral friction force generated by braking. The elastic fit between the recess 53 and the rubber filler strip 25 is used to buffer the impact force during braking and maintain the stability of the overall structure.
