Description

Technical Field

[0001] The utility model relates to the technical field of oil storage pots, in particular to an oil storage pot for an automotive brake master cylinder. Background Technique

[0002] The volume of the brake oil changes with the temperature. Therefore, a vent hole is provided on the brake oil storage pot to maintain pressure balance. The brake oil contacts the outside air through the vent hole. The brake fluid has strong water absorption. If the brake fluid contacts the outside air, the moisture in the air will be absorbed by the brake fluid, increasing the water content of the brake fluid, resulting in air resistance during the operation of the brake fluid, affecting driving safety, and in severe cases, causing brake failure. Content of the Utility Model

[0003] The purpose of the utility model is to solve the disadvantages existing in the prior art, and to propose an oil storage pot for an automotive brake master cylinder.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] Design an oil storage pot for an automotive brake master cylinder, including a pot body. An installation ring is integrally formed in the middle of the inner cavity of the pot body. An airbag is hermetically arranged on the installation ring. An oil inlet pipe is arranged on the side wall of the pot body. The top of the oil inlet pipe is threadedly connected with a sealing screw cap. The top of the pot body is threadedly connected with a top cover.

[0006] Preferably, a sealing ring is arranged on the outer wall ring side of the airbag. A plurality of fastening screws are threadedly connected to the sealing ring. The sealing ring is fixed on the installation ring through the fastening screws.

[0007] Preferably, a connecting pipe is connected to the outer wall of the airbag. The end of the connecting pipe is connected with an inflatable airbag.

[0008] Preferably, the connecting pipe includes a section of rigid pipe and a section of flexible pipe. A jack is opened on the outer wall of the pot body. The rigid pipe passes through the jack.

[0009] Preferably, a filter screen is arranged at the top opening of the pot body. The filter screen is clamped between the pot body and the top cover.

[0010] Preferably, the oil inlet pipe is arranged in an inclined shape. A liquid level sensor is arranged on the sealing screw cap. The liquid level sensor is connected to the automotive main control through a wire.

[0011] An oil storage pot for an automotive master cylinder proposed by the present utility model has the beneficial effects that: by providing an airbag, a sealing ring and a mounting ring, the airbag is arranged at the mounting ring through the sealing ring. Brake fluid is injected into the pot body through the inlet pipe and then into the automotive braking system through the outlet pipe. When the pressure inside the pot body changes, the airbag plays a role in balancing the pressure and at the same time covers the brake fluid in the pot body to prevent moisture from entering the brake fluid, avoiding moisture contamination of the brake fluid. At the same time, the provided filter screen plays a filtering role to prevent dirt from contaminating the brake fluid, ensuring the cleanliness of the brake fluid and enhancing driving safety.
