The application of automobile brake pumps in life is mainly reflected in their working principle and role in the automobile braking system.
Working principle
The working principle of the brake pump mainly includes two methods: hydraulic braking and pneumatic braking:
Hydraulic braking: When the brake pedal is pressed, the piston in the master brake cylinder is thrust, and the brake oil is transmitted to the pistons of each brake cylinder through the push rod, pushing the brake shoe outward, so that the brake pads and the inner surface of the brake drum produce friction, thereby achieving the braking effect.
Pneumatic braking: The working principle of the pneumatic master brake cylinder is similar to that of the hydraulic type. The difference is that pneumatic vehicles are usually equipped with air tanks, and the gas is directly discharged after the braking is completed.
Role in the automobile braking system
The brake pump is the core component of the automobile braking system, and its main functions include:
Transmitting brake pressure: The brake pump transmits and controls the brake pressure to ensure that each brake can be accurately and effectively executed, thereby achieving the deceleration and stop of the vehicle.
Ensure driving safety: The quality of the brake pump directly affects the braking performance and driving experience of the vehicle. High-quality brake pumps can ensure the stability and reliability of the braking system, thereby ensuring driving safety. Maintenance and troubleshooting
In daily use, the maintenance and troubleshooting of the brake pump are also very important:
Maintenance: Check the working status of the brake pump regularly to ensure its normal operation. Pay attention to the quality and amount of brake fluid to avoid fluid contamination and insufficient fluid.
Troubleshooting: If the brake pump makes an abnormal sound or the braking effect is poor, it may be caused by problems such as piston ring jamming or deformation of the iron plate that fixes the brake pad. At this time, professional inspection and maintenance are required to ensure the normal operation of the brake system.
