Description

The automatic cycle brake system of automatic circulating system and structure thereof
Technical field
The present invention relates to brake system, especially relate to a kind of can realize and entirely imitate the automatic circulating system of braking and the automatic cycle brake system of structure thereof by braking liquid automatic cycle applicable to vehicles such as loaders.
Background technology;
The residing working environment of the engineering trucks such as loader is very severe, and needs the high strength in the short time frequently to brake, and therefore the safety to brake system, validity and reliability are had relatively high expectations.Existing brake system is all generally fairly simple conventional structure, and safety, validity and reliability are poor, can not meet its requirement.Existing brake system structure is as shown in the Fig. 1 in Figure of description.Each mark in Fig. 1 represents; 1. combined pressure regulating valve, 2. air receiver, 3. main valve, 4. booster pump, 5. brake clamp, 6. brake clamp, 7. booster pump group, 8. brake clamp group, 9. brake clamp group.Its principle of work is:
Add braking liquid: braking liquid is joined in the lubricating cup of booster pump group 7, open the bleeder screw of booster pump group 7, until full the overflowing again of braking liquid locked.Open the bleeder screw of each brake clamp upper end of brake clamp group 5 and 9, until each relief port all has full braking liquid to overflow, then locking one by one.Then examination brake.Braking effect is below standard, repeatedly repeat above process, until braking effect reaches standard.
Braking: step on the pedal of main valve 3, main valve is inflated booster pump group 7, booster pump group output braking liquid is realized braking to brake clamp group 5 and 9 supercharging.
Brake off: unclamp main valve pedal, booster pump group is by total valve exhaust, and braking liquid reduces pressure gradually and is discharged in the oil cylinder of booster pump group, thereby brake off.
Mainly there is following defect in existing brake system:
1) add braking liquid very loaded down with trivial details, work capacity is larger, can not ensure the completely full of braking liquid.
2) braking liquid can not automatic cycle, and when braking, booster pump output braking liquid is realized booster brake.After brake off, braking liquid energy adverse current is returned booster pump inside or lubricating cup.Therefore braking liquid can not circulate.
3) vapour lock cannot thoroughly be got rid of automatically.Hydraulic efficiency pressure system inside or brake clamp are inner can produce vapour lock, and existing system can not be got rid of automatically, needs manual emission, brakes weak or loses efficacy if discharge thoroughly can cause not in time.Brake clamp cooling.Brake clamp is meeting heat-dissipating in the time of braking, lacks cooling measure and setting, and high strength frequently braking can cause brake clamp temperature sharply to raise, cause braking liquid gasification, produce a large amount of vapour locks, cause braking weakness or lost efficacy, have the poor factor of serious potential safety hazard and reliability.
4) pollute booster pump.Brake pipe is docked at brake clamp middle part, and brake clamp is inner can produce corrosion or impurity, generally can be gathered in middle and lower part, in the time that braking liquid is back to booster pump, can produce pollution, when seriously polluted, can cause braking failure.
5) full effect braking; The vapour lock of hydraulic efficiency pressure system inside all can produce constantly, but mode that can manual emission vapour lock but can not discharge constantly, can not all ensure constantly full effect braking, has the problem that brake efficiency is lower.
6) braking and brake off are slower.Main valve is directly booster pump inflation and exhaust, and the inflation extraction flow of main valve is limited, if can be slower away from from booster pump, has braking and the slower problem of brake off.Except the lower alerting ability of usefulness is poor, also can cause the generation of many secondary problems such as brake clamp heat-dissipating.
7) lack the strick precaution to impurity; Between booster pump and brake clamp, be open interactive, be easily subject to the pollution of the especially destructive impurity of impurity, lack protection setting.
