Description

Technical Field

[0001] This utility model relates to the field of brake cup technology, specifically to a high wear-resistant and anti-aging type brake cup for automobiles. Background Technology

[0002] The vehicle braking system is a key part of ensuring vehicle driving safety, and the performance of the piston cup, as an important sealing element in the braking system, directly affects the braking effect and the reliability of the system.

[0003] Existing technology typically uses bolts to fix the diaphragm cup to the brake lever, so that the diaphragm cup can be quickly pulled back to its original position when the brake lever retracts, so as to prevent the diaphragm cup from failing to return to its initial position in time due to its own elastic lag.

[0004] However, this design often causes the diaphragm cup to be pulled excessively under the inertia of the brake lever's contraction, resulting in minor damage to the internal structure of the diaphragm cup. As braking operations are performed frequently, these minor damages gradually accumulate, causing the sealing performance of the diaphragm cup to decline. Utility Model Content

[0005] To solve the above-mentioned technical problems, a high wear-resistant and anti-aging type automotive brake cup is provided, which solves the problems existing in the background technology.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a high wear-resistant and anti-aging type automotive brake cup, comprising two pump covers symmetrically distributed vertically and a cup body pressed between the two pump covers, a brake rod retracting through the inner wall of the top of the upper pump cover, and an anti-inertia reverse pull mechanism.

[0007] The anti-inertia reverse pull mechanism consists of a buffer-type connecting seat and a limiting coordinating frame. The buffer-type connecting seat is located between the brake rod and the main body of the diaphragm. There are two sets of limiting coordinating frames, which are symmetrically distributed on both sides of the buffer-type connecting seat.

[0008] Preferably, the buffer-type connecting seat includes an assembly seat that is fixed to the top of the diaphragm body by bolts, and a separation seat that is elastically connected to the assembly seat and perpendicularly fixed to the end of the brake lever.

[0009] Preferably, the limiting coordination frame includes a telescopic rod hinged between the outer wall of the mounting base and the inner wall of the pump cover, and an inclined stop frame abuts against the telescopic rod, the stop frame being fixed to the inner side wall of the pump cover.

[0010] Preferably, a T-shaped rod that is fixedly connected to the assembly seat passes through the inner wall on both sides of the separating seat, and a spring is sleeved on the vertical section of the T-shaped rod, with the spring located above the separating seat.

[0011] Preferably, the pump cover consists of an inner layer, a middle layer, and an outer layer. The inner layer is a nitrile rubber layer, the middle layer is a reinforcing layer, and the outer layer is a fluororubber layer. The reinforcing layer is woven from aramid fibers.

[0012] Compared with the prior art, the advantages of this utility model are:

[0013] (1) By setting up the anti-inertia reverse pull mechanism, the inertia reverse pull of the brake rod on the main body of the diaphragm can be effectively limited, thereby avoiding damage to the main body of the diaphragm caused by the reverse pull of the brake rod and improving the service life of the main body of the diaphragm.

[0014] (2) The inner nitrile rubber layer has good oil resistance and sealing properties, which can effectively prevent brake fluid leakage and ensure the normal operation of the braking system. The middle reinforcing layer is woven from aramid fiber. Aramid fiber has the characteristics of high strength and high modulus, which can significantly improve the overall strength and wear resistance of the diaphragm and reduce wear during use. The outer fluororubber layer has excellent aging resistance and can effectively resist the corrosion of ultraviolet rays, high temperature and chemicals, and extend the service life of the diaphragm.

[0020] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0021] Reference Figure 1-3 As shown, the high wear-resistant and anti-aging type automotive brake cup includes two pump covers 1 symmetrically distributed vertically and a cup body 3 pressed between the two pump covers 1. A brake lever 2 is inserted into the inner wall of the top of the upper pump cover 1. It also includes an anti-inertia reverse pull mechanism.

[0022] By setting up an anti-inertia reverse pull mechanism, the inertial reverse pull of the brake lever 2 on the diaphragm body 3 can be effectively limited, thereby avoiding damage to the diaphragm body 3 caused by the reverse pull of the brake lever 2 and improving the service life of the diaphragm body 3.

[0023] Specifically, refer to Figure 1 and Figure 2 As shown, it is worth noting that the anti-inertia reverse pull mechanism consists of a buffer-type connecting seat and a limiting coordinating frame. The buffer-type connecting seat is located between the brake rod 2 and the main body 3 of the piston cup. There are two sets of limiting coordinating frames, which are symmetrically distributed on both sides of the buffer-type connecting seat.

[0024] The buffer-type connecting seat includes an assembly seat 4 that is fixed to the top of the diaphragm body 3 by bolts, and a separation seat 7 that is elastically connected to the assembly seat 4 and is fixed perpendicularly to the end of the brake lever 2.

[0025] The limiting coordination frame includes a telescopic rod 10 hinged between the outer wall of the mounting base 4 and the inner wall of the pump cover 1. The telescopic rod 10 abuts against an inclined stop frame 11 on its body. The stop frame 11 is fixed to the inner wall of the pump cover 1.

[0026] T-shaped rods 8, which are fixed to the assembly seat 4, are passed through the inner walls on both sides of the separation seat 7. A spring 9 is sleeved on the vertical section of the T-shaped rod 8, and the spring 9 is located above the separation seat 7.

[0027] With the setting of buffer-type connecting seat and limit coordination frame, when the brake lever 2 extends into the inner cavity of the pump cover 1 to squeeze the main body 3 of the cup, the brake lever 2 can simultaneously squeeze the separation seat 7 and the assembly seat 4 as a whole, so that the assembly seat 4 pulls the telescopic rod 10 during the downward movement, and the telescopic rod 10 extends and rotates at the same time, so as not to hinder the extension of the brake lever 2.

[0028] When the brake lever 2 retracts in the opposite direction, the brake lever 2 can be simultaneously pulled by the separation seat 7 and the assembly seat 4 to drive the diaphragm body 3 to reset, so as to prevent the diaphragm body 3 from failing to return to its initial state in time due to its own elastic lag.

[0029] After the main body 3 of the leather cup is fully reset by the brake lever 2, the telescopic rod 10 abuts against the stop frame 11. The stop frame 11 can effectively limit the telescopic rod 10 and the assembly seat 4 as a whole, preventing the assembly seat 4 from pulling the main body 3 of the leather cup back along with the inertial contraction of the brake lever 2.

[0030] Furthermore, during the inertial retraction of the brake lever 2, force can only be applied to the release seat 7, causing the release seat 7 to slide along the body of the T-shaped rod 8 and compress the deformation of the spring 9. In this way, by utilizing the elastic force of the spring 9, when the inertial force of the brake lever 2 is eliminated, the release seat 7 can be reset and closely adhered to the mounting seat 4 under the elastic force of the spring 9, which is convenient for secondary use.

[0031] Furthermore, referring to Figure 3As shown, it is worth noting that the pump cover 1 is composed of an inner layer, a middle layer and an outer layer. The inner layer is a nitrile rubber layer 5, the middle layer is a reinforcing layer 6, and the outer layer is a fluororubber layer 12. The reinforcing layer 6 is woven from aramid fibers.

[0032] The inner nitrile rubber layer 5 has good oil resistance and sealing properties, which can effectively prevent brake fluid leakage and ensure the normal operation of the braking system. The middle reinforcing layer 6 is woven from aramid fibers. Aramid fibers have the characteristics of high strength and high modulus, which can significantly improve the overall strength and wear resistance of the brake cup and reduce wear during use. The outer fluororubber layer 12 has excellent aging resistance and can effectively resist the corrosion of ultraviolet rays, high temperature and chemicals, thus extending the service life of the brake cup.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model.
