Problems solved by technology

Therefore the brake fluid cannot circulate
[0009] 3) The air resistance cannot be completely eliminated by force
Brake calipers will generate heat when braking, lack of cooling measures and settings, high-intensity frequent braking will cause the temperature of the brake calipers to rise sharply, cause the brake fluid to vaporize, generate a large amount of air resistance, and cause brake weakness or failure , there are serious safety hazards and poor reliability factors
[0010] 4) Pollution booster pump
The brake oil pipe is connected to the middle of the brake caliper. Rust or impurities will be generated inside the brake caliper, which will generally gather in the middle and lower parts. When the brake fluid returns to the booster pump, pollution will occur, and serious pollution will cause brake failure.
[0011] 5) Full-effect braking; the air resistance inside the hydraulic system will be generated from time to time, but the method of manually releasing the air resistance cannot always discharge, and the full-effect braking cannot be guaranteed all the time, and there is a problem of low braking efficiency
[0012] 6) Braking and releasing the brakes are slow
In addition to low efficiency and poor flexibility, it will also cause many secondary problems such as heat generation of brake calipers.
[0013] 7) Lack of protection against impurities; the booster pump and the brake caliper are open and interactive, and are easily polluted by impurities, especially destructive impurities, and lack protection settings
[0014] No reports have been found on the forced circulation system and the forced circulation brake system it is built on

Description

technical field [0001] The invention relates to a braking system, in particular to a forced circulation system which can be applied to vehicles such as loaders and can realize full-effect braking through the forced circulation of brake fluid and the constructed forced circulation braking system. Background technique [0002] The working environment of engineering vehicles such as loaders is very harsh, and high-intensity frequent braking is required in a short period of time, so the safety, effectiveness and reliability of the braking system are highly required. Existing brake systems are generally of relatively simple conventional structure, poor in safety, effectiveness, and reliability, and cannot meet the requirements thereof. Existing braking system structure is as shown in the accompanying drawings figure 1 shown. figure 1 Each mark in represents; 1. Combined pressure regulating valve, 2. Air storage tank, 3. Master valve, 4. Afterburner pump, 5. Brake caliper, 6. Br...
