| The clutch booster pumps provides the power for the clutch separation, reduces weariness which the pilot operates, its structure simple, the weight light, the transmission efficiency high, the work is reliable, widely uses in to hit, on the heavy truck. Therefore boosts the reliability which pumps to be extremely important. This article in this kind of foundation, introduced the coupling boosts pumps in the principle, proposed the formula, analyzed with emphasis has boosted pumps the breakdown pattern, and proposed the improvement method, the experiment proved, after the improvement coupling has discharged the original breakdown pattern, each kind of performance and the life had the enhancement. Through we nearly more than year of trying to find out with the practice, to boosts pumps goes into production several kind of major failures which the initial period occurs, carried on massively has opened examines with the fault analysis, repeatedly the proof and the experiment, gradually took the improvement measure and applies to presently produces, enable the quality level which boosted pumps to have the distinct enhancement, while ago, carried on in a steam automobile research institute boosts pumps in the product quality re-check, to my factory, Zhejiang Switzerland stood with Shanxi sets the prairie afire three units to boost pumps the product, has made the performance and the reliable contrast experiment, the result we boosts pumps the product smoothly through the bench test, And surpasses other two factories in certain performance aspects. The practice proved that, boosts in view of above several kinds pumps often sends the improvement measure which the breakdown adopts, has received the quite tangible result, had achieved the anticipated effect, boosts pumps the product the performance and the reliability gradually moves towards stable and is mature. This ten thousand research results induces into following several points: 1. Aims at the diaphragm type coupling the composition and the principle of work carries on the detailed introduction, and summary coupling control mechanism computational method, including clutch pedal free stroke computation, clutch pedal overall travelling schedule computation, clutch pedal strength computation, coupling mode of failure footboard strength computation as well as clutch pedal strength examination. 2. Aims at the coupling to boost pumps the actual effect the reason, develops the coupling breakdown diagnosis method, and refers to several kind of typical couplings to boost pumps, analyzes its common expiration reason, and produces solution. Simultaneously acts according to many years coupling to boost pumps the production experience, summarizes boosts pumps the breakdown pattern, the analysis breakdown reason, proposes the improvement measure. 3.Introductions couplings control mechanism test platform principle and work way. Emphatically elaborated set of advanced couplings boost pump the test equipment, the coupling boost pump the CAT system, to its principle of work, the hardware equipment, the software environment has carried on the detailed analysis. Simultaneously aims at the coupling expiration reason which summarizes, and the improvement carried on the experimental analysis, the analysis result had indicated, the improvement method and the measure had the tangible effect, conforms to "Coupling Boosted Pumps Always Becomes Engineering factor" requirement. Enhanced my factory production coupling to boost pumps in the market the competitive ability, simultaneously has won the customer trust. 4. Pair of clutch will boost pump the future the development direction to make the analysis. |
