Description
Technical field
The utility model belongs to the automobile operation field, is specifically related to a kind of automatic control type servo-steering pumping system.
Background technology
Automobile steering system is for keeping or change the mechanism of vehicle traveling direction, being divided into two kinds of forms of mechanical steering and power steering (being called again servo-steering).Wherein, mechanical steering is to rely on the hand-power of chaufeur to rotate steering handwheel, through deflector and steering gear, makes wheel flutter deflection, and power steering is on the basis of mechanical steering, installs power system additional, and alleviates the hand-power of chaufeur by this system.Automobile assisted power steering system comprises automobile power-assisted steering pump and deflector, drives automobile steering roller to realize the motor turning function, and the effect of automobile power-assisted steering pump is for steering swivel system provides required propulsion source, is " heart " position of steering swivel system.
When automobile during at low speed driving, because friction force is larger, only depend on the muscle power of chaufeur to be difficult to successfully realize turning to, at present, in developed country, the power-assisted steering pump entrucking rate of large roadlice has approached 100%, and domestic many vehicles have started to adopt power steering, adopt separately the automobile of mechanical steering fewer and feweri.
It is several that power-assisted steering pump mainly contains blade, gear type, plunger tpe etc.From current domestic development, promoting the use of maximum is blade-type pump.Vital parts has stator, rotor, oil distribution casing, blade, the pump housing and bonnet etc.Flow-controlling gate and safety valve are housed in the pump housing.When pump work, guiding valve has certain aperture, makes flow reach the regulation requirement, and unnecessary flow is got back to again in the smoking chamber of pump.If oil circuit occurs to stop up or contingency, while making system pressure surpass the maximum working pressure (MWP) of pump, safety valve is opened, and guiding valve is all opened, and all pressure oils are all got back to oil sucting cavity, and system is played to the safety guard-safeguard effect.
When automobile when running at high speed, because friction force is less, do not need power-assisted steering pump to provide power just can successfully turn to, but existing automobile is in the process of moving, and power-assisted steering pump is connected with driving engine always, can't be automatically and the driving engine disconnection, thereby cause the waste of the energy, especially along with the developing rapidly of auto-industry, automobile grows with each passing day in global recoverable amount, wastes more obvious.
The utility model content
The utility model provides a kind of automatic control type servo-steering pumping system, can make as required power-assisted steering pump and driving engine disconnect or combination, thus reduce the load of driving engine and user use the car cost.
