What is the car brake master pump with pot
Automobile brake master pump with pot is an important part of automobile brake system, its main function is to store brake oil, and transfer brake force through the hydraulic system, so as to achieve vehicle deceleration or stop. The brake master pump is usually located in the engine compartment and is connected to the brake oil pot and brake subpump.
Working principle of brake master pump
When the driver presses the brake pedal, the piston in the brake master pump is pushed by the pedal, which compresses the brake oil. The compressed brake oil is transferred to each brake pump through the oil pipe, and the piston in the pump is pushed to contact the brake pad with the brake drum after the pressure, generating friction, so as to achieve the braking effect. When the brake pedal is released, the brake oil flows back to the master pump, ready for the next brake .
Brake oil can function
The brake oil pot is used to store brake oil and ensure that the brake system has enough hydraulic media. The brake oil pot is designed with pressure balance in mind, allowing air to enter and exit through vents to maintain a stable pressure in the oil pot. Because the air contains water vapor, the brake oil in the brake oil pot will gradually absorb water, which will affect the brake performance, so it is necessary to check and replace the brake oil regularly.
The main function of the brake master pump is to store brake oil and transfer braking force through brake oil.
The brake master pump is one of the core components of the automotive brake system, and its main responsibility is to drive the friction between the brake pad and the brake drum to achieve vehicle deceleration and even standstill. When the driver presses the brake pedal, the piston in the brake master pump is driven by the pedal, and the brake oil pressure is transmitted to the sub-pumps through the action of the push rod. This process spreads the brake shoes outward, ensuring that the brake pads are in contact with the inside of the brake drum, producing a braking effect .
The specific functions of the brake master pump with the pot include:
Store brake oil : The brake oil pot is used to store brake oil to ensure that the brake system has enough hydraulic media to work .
pressure balance : The brake oil pot is designed to allow air to enter and exit to maintain the pressure balance within the brake system. When the brake is pressed on, the air in the brake oil pot is sucked in, and when the brake is released, the air is discharged, so as to keep the system working normally .
prevent air from entering : the lid of the brake oil pot is designed with a vent hole and a sealing gasket to ensure that the outside air can enter when the brake is pressed, and the air can be discharged when the brake is released, so as to prevent air from entering the brake oil and affect the braking effect .
The working principle of the car brake pump with pot mainly includes the following steps:
Brake pedal operation : When the driver presses the brake pedal, the piston in the brake master pump is thrust, and this thrust is transmitted to the brake oil through the push rod.
pressure transfer : brake oil produces pressure in the oil circuit and is transmitted to the brake pump piston of each wheel through the oil pipe.
braking action : the branch pump piston is under pressure to push the brake pads outwardly, so that the brake pads and the brake drum friction, produce enough friction to reduce the wheel speed, to achieve braking .
pressure release : after releasing the brake pedal, the rotation of the wheel will make the piston of the branch pump reset, the hydraulic oil returns to the oil pot of the main brake pump through the pipeline, and the brake can be released .
In addition, the design of the brake master pump with pot also includes some key components and functions:
Piston and push rod : The piston is pushed by the brake pedal and pushes the brake fluid, and the push rod acts as a force transfer.
oil can : Store brake oil to ensure that there is sufficient oil pressure supply during braking.
In terms of maintenance and maintenance, it is recommended to check the level and quality of the brake oil regularly to ensure that the oil is clean and free of moisture, because moisture will reduce the boiling point of the brake oil and affect the braking effect. At the same time, regular replacement of brake oil and cleaning of the brake system can extend the service life of the master brake pump and ensure driving safety .
