Description

Technical Field

[0001] The utility model belongs to the technical field of ball head accessories, in particular to a wear-resistant gasket for a car ball head. Background Art

[0002] The gasket is a commonly used seal in the automobile tie rod ball head. It is installed on the top of the dust cover and cooperates with the dust cover to seal and protect the head of the ball head.

[0003] like Figure 7 As shown, the automobile ball head gasket in the prior art has a thin structure, is easily damaged under pressure, and has poor wear resistance. Summary of the invention

[0004] The utility model aims to solve the above technical problems existing in the prior art and provide a wear-resistant gasket for a car ball head, which has novel structure, reliable strength, good wear resistance and long service life.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] The wear-resistant gasket for automobile ball head comprises: a gasket body, the gasket body is provided with a middle hole, and is characterized in that: a frame is provided in the gasket body, the frame comprises annular ribs and straight ribs, and the straight ribs are distributed around the annular ribs; a receiving groove is provided on the inner wall of the gasket body, and a solid lubricant is provided in the receiving groove. The wear-resistant gasket has a novel structure, reliable strength, good wear resistance and long service life.

[0007] Furthermore, a metal protective ring is provided on the outer side of the gasket body. During use, the ball pin of the ball head will continuously squeeze the gasket body, causing continuous friction between the outer wall of the gasket body and the dust cover, resulting in wear of the gasket body and poor sealing. The metal protective ring protects the outer wall of the gasket body, is not easy to wear, and is durable.

[0008] Furthermore, the straight ribs are connected to the metal protection ring to form a mutual restraint relationship, which indirectly improves the connection strength between the straight ribs and the gasket body.

[0009] Furthermore, the metal protection ring is bonded to the gasket body, the connection is firm, the fixation is convenient, and the metal protection ring is replaceable.

[0010] Furthermore, convex ribs are provided on the straight ribs, and the convex ribs reinforce the gasket body axially, making it resistant to pressure and collision and not easy to be damaged, thereby extending the service life of the gasket body.

[0011] Furthermore, the surface of the gasket body is coated with a wear-resistant layer, which can be made of a copper-zinc alloy layer, has good wear resistance and is not easy to wear and rust, thereby extending the service life of the gasket body.

[0012] The utility model has the following beneficial effects due to the adoption of the above technical solution:

[0013] 1. The straight ribs play a role in radial reinforcement of the gasket body, so that the gasket body can withstand the radial extrusion pressure of the ball pin. The ring ribs connect the straight ribs into one, forming a reliable reinforcement body with a large reinforcement range and good effect, which effectively improves the structural strength of the gasket body.

[0014] 2. The convex ribs play an axial reinforcement role on the gasket body, and the straight ribs play a radial reinforcement role on the gasket body, which greatly improves the structural strength of the gasket body, is pressure-resistant and collision-resistant and not easy to break, thereby extending the service life of the gasket body.

[0015] 3. The ball pin will generate heat as the ball head rotates. The heat is transferred to the inner wall of the gasket body. The solid lubricant melts due to the heat and lubricates the contact surface between the ball pin and the gasket body, achieving the purpose of wear resistance and realizing the effect of self-lubrication.

[0016] 4. During use, the ball pin of the ball head will continuously squeeze the gasket body, causing the outer wall of the gasket body and the dust cover to constantly rub against each other, resulting in wear of the gasket body and poor sealing. The metal protective ring protects the outer wall of the gasket body. The metal protective ring is not easy to wear and is durable. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] like Figure 1 , Figure 2 As shown, this is an embodiment of the present utility model

[0027] The automobile ball head wear-resistant gasket comprises: a gasket body 1, a middle hole 2 is arranged on the gasket body 1, and a wear-resistant layer is coated on the surface of the gasket body 1. The wear-resistant layer can be made of a copper-zinc alloy layer with good wear resistance and is not easy to wear and rust, thereby extending the service life of the gasket body 1.

[0028] A skeleton 3 is provided inside the gasket body 1, and the skeleton 3 includes annular ribs 4 and straight ribs 5, and the straight ribs 5 are distributed around the annular ribs 4. The straight ribs 5 play a role of radial reinforcement for the gasket body 1, so that the gasket body 1 can withstand the radial extrusion force of the ball pin, and the annular ribs 4 connect the straight ribs 5 into one body to form a reliable reinforcement body with a large reinforcement range and good effect, which effectively improves the structural strength of the gasket body 1.

[0029] The inner wall of the gasket body 1 is provided with a receiving groove, in which a solid lubricant 6 is arranged. The ball pin generates heat as the ball head rotates, and the heat is transferred to the inner wall of the gasket body 1. The solid lubricant 6 melts due to the heat, lubricating the contact surface between the ball pin and the gasket body 1, achieving the purpose of wear resistance and realizing the effect of self-lubrication.

[0030] like Figure 3 , Figure 4 As shown, this is the second embodiment of the utility model

[0031] In the technical solution based on the first embodiment, a metal protective ring 7 is provided on the outer side of the gasket body 1. The metal protective ring 7 can be made of one of iron, copper and aluminum. During use, the ball pin of the ball head will continuously squeeze the gasket body 1, causing the outer wall of the gasket body 1 and the dust cover to continuously rub against each other, resulting in wear of the gasket body 1 and poor sealing. The metal protective ring 7 protects the outer wall of the gasket body 1, is not easy to wear and is durable.

[0032] The metal protection ring 7 is bonded to the straight rib 5 to form a mutual restraint relationship, which indirectly improves the connection strength between the straight rib 5 and the gasket body 1. The metal protection ring 7 is bonded to the gasket body 1, the connection is firm, the fixation is convenient, and the metal protection ring 7 is replaceable.

[0033] like Figure 5 , Figure 6 As shown, this is the third embodiment of the present utility model

[0034] In the technical solution based on the first embodiment, a convex rib 8 is provided on the straight rib 5, and the convex rib 8 axially reinforces the gasket body 1, and cooperates with the straight rib 5 to radially reinforce the gasket body 1, thereby greatly improving the structural strength of the gasket body 1, making it pressure-resistant and collision-resistant and not easy to break, thereby extending the service life of the gasket body 1.

[0035] The above are only specific embodiments of the utility model, but the technical features of the utility model are not limited thereto. Any simple changes, equivalent replacements or modifications made based on the utility model to solve basically the same technical problems and achieve basically the same technical effects are all included in the protection scope of the utility model.
