Description

Technical Field

[0001] The utility model relates to the technical field of automobile braking, in particular to a sealing diaphragm for a master cylinder. Background Art

[0002] The master cylinder sealing diaphragm is a component used in the oil tank container of the car. Its main function is to ensure a good sealing effect between the oil tank cover and the oil tank mouth to prevent the brake fluid stored inside from overflowing or evaporating, and also to prevent external impurities from entering the oil tank and contaminating the liquid. Specifically:

[0003] 1. Prevent leakage: By setting a circle of flexible and oil-resistant sealing ring on the contact surface between the oil pot cover and the oil pot mouth, when the oil pot cover is closed, the sealing ring is compressed and deformed to form an effective sealing barrier to prevent oil from leaking from the interface.

[0004] 2. Isolate air and impurities: The sealing ring can effectively isolate impurities such as moisture and dust in the air from entering the oil pot, which is crucial to ensure the purity and performance of automotive oil, especially for some brake systems that are sensitive to moisture and impurities. In short, to ensure the normal operation of the brake system, the structural design of the oil pot diaphragm is particularly important.

[0005] In order to help the diaphragm better adjust its own shape, thereby ensuring the sealing effect and reducing the possibility of air being sucked into the brake system, and increasing the overall strength and rigidity of the diaphragm, the utility model proposes a sealing diaphragm for a master cylinder.

[0018] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar symbols throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0019] like Figure 1 A sealing diaphragm for a master cylinder shown in the figure comprises a diaphragm 4, which is a prior art, and has an incision 1 formed thereon, a first reinforcing rib 2 installed on one side of the diaphragm 4, and a second reinforcing rib 3 installed on the other side of the diaphragm 4, the first reinforcing rib 2 being used to enhance the sealing effect, and the second reinforcing rib 3 being used to increase the overall strength and rigidity of the diaphragm 4, and reinforcing ribs in the prior art being installed on the other side of the diaphragm 4 and on both sides of the second reinforcing rib 3, and the reinforcing ribs in the prior art are triangular-shaped prior art reinforcing ribs;

[0020] The shape of the second reinforcing rib 3 is set to be trapezoidal, the first reinforcing rib 2 and the second reinforcing rib 3 are integrally formed with the diaphragm 4, the side of the first reinforcing rib 2 away from the diaphragm 4 is arched, the number of the first reinforcing ribs 2 is set to two and they are symmetrically distributed, and the number of the second reinforcing ribs 3 is set to two and they are symmetrically distributed.

[0021] Cutout 1: When the brake system is filled with new brake fluid or the brake fluid is refilled after the brake parts are replaced, the cutout 1 on the diaphragm 4 allows air to be discharged, which is convenient for the exhaust operation of the brake system and ensures that the entire brake line is full of liquid and free of air;

[0022] The first reinforcing rib 2 is to add a reinforcing rib on the back of the original reinforcing rib, which can help the diaphragm 4 to better adjust its shape, thereby ensuring the sealing effect and reducing the possibility of air being sucked into the brake system;

[0023] Second reinforcing rib 3: The original triangular reinforcing rib structure is changed into a trapezoidal one, and the design plane of the reinforcing rib is increased, so that the overall strength and rigidity of the diaphragm 4 are increased.

[0024] The present application relates to a sealing diaphragm 4 component for a master cylinder, which is formed by rubber vulcanization. Through the arrangement of the first reinforcing rib 2, the diaphragm 4, on the basis of ensuring the original sealing performance, enhances the structural stability of the diaphragm 4 by adding the first reinforcing rib 2. The arrangement of the first reinforcing rib 2 protrudes from the diaphragm 4 to prevent rupture or failure under frequent vibration or high pressure conditions. Through the arrangement of the second reinforcing rib 3, the shape is set to be trapezoidal, and the design plane of the second reinforcing rib 3 is increased, so that the overall strength and rigidity of the diaphragm 4 are increased, ensuring that the diaphragm 4 is not easily deformed or damaged, and maintaining a good sealing effect.
