Abstract
The utility model discloses an energy-saving automotive hydraulic power-assisted steering oil pump, which comprises a steering oil pump body and a belt pulley installed on a pump shaft. The belt pulley is provided with an electromagnetic clutch which is electrically connected with a steering gear controller through a clutch lead assembly. The belt pulley with the electromagnetic clutch is additionally installed on the pump shaft of the traditional steering oil pump body, so that working conditions of the steering oil pump can be controlled through engagement and separation of the electromagnetic clutch on the belt pulley. The energy-saving automotive hydraulic power-assisted steering oil pump can work or stop working according to steering requirements, saves kinetic energy of an engine, reduces oil consumption and discharge of carbon dioxide, uses a mature structure at present and does not need improvement, thereby being low in cost and easy to retrofit in the prior art.
Description
Technical field
The utility model relates to a kind of automobile hydraulic power-assisted steering system, especially relates to a kind of energy-saving automobile-used hydraulic power-assisted steering oil pump.
Background technology
Electro-hydraulic servo steering system primary member: petrol storage tank, servo-steering control unit, motor-drive pump, steering box, servo-steering sensor etc., wherein servo-steering control unit and motor-drive pump are integral structures.Principle of work: the electro-hydraulic steering boost system has overcome the shortcoming of traditional hydraulic power-assisted steering system.The Hydraulic Pump that it adopts ends the dependence upon the dynamo belt direct drive, but adopts a motor-drive pump, and the state of the work that it is all is the perfect condition that is gone out according to calculated signals such as the moving velocity of vehicle, steering angles by electronic control unit.Briefly, when low speed turned to greatly, it is more high-power that electronic control unit drives electro-hydraulic pump at high speed running output, and it is laborsaving to make chaufeur beat direction; Automobile is when running at high speed, and hydraulic control unit drives the electro-hydraulic pump with lower speed running, be unlikely to influence spin at a high speed to need save a part of engine power simultaneously.
The automobile power steering oil pump is the dynamical element that provides hydraulic pressure can change and recover vehicle traveling direction to hydraulic power steering device in the automobile steering system, and it serves as that the basis combines the combine valve of pressure-gradient control valve and flow-controlling gate to form with traditional blade-type pump technology.
Conventional steering oil pump type of drive is to be driven through belt pulley by driving engine, and whether the power steerig pump mode of operation can only be determined by engine behavior need work irrelevant with steering pump.
In addition, also have the electric hydraulic power-assisted steering pump, by motor direct-drive, thereby and control the motor operation by control unit and change the power steerig pump mode of operation, though can satisfy according to turning to needs adjustment oil pump mode of operation, complex structure, cost is higher.
One Chinese patent application number is 200610086002.2 to disclose a kind of electrohydraulic power steering pump, and it installs an electromagnetic proportional valve additional in common fluid-link steering oil pump exit, constitutes a later-model integral type electricity liquid power-assisted oil pump.It is to install an electromagnetic proportional valve additional by former power steerig pump, adds electronic controller (CPU) and forms.Thereby technique scheme provide a kind of in use can with the speed of a motor vehicle improve reduce gradually oil pump output oil mass gradually the augment direction dish turn to hand-power.But can not when driving engine moves, work continuously by the conventional steering oil pump, even the also problem of consumption of engine takeoff output need not turn to the time.
The utility model content
The technical matters that the utility model will solve is in order to overcome technological deficiency recited above, a kind of energy-saving automobile-used hydraulic power-assisted steering oil pump to be provided.
In order to solve technical matters recited above, the utility model is taked following technical scheme:
A kind of energy-saving automobile-used hydraulic power-assisted steering oil pump; Include the power steerig pump body and be installed in the belt pulley on the pump shaft; Described belt pulley is the belt pulley of charged magnetic clutch, and described magnetic clutch is electrically connected with the deflector controller through power-transfer clutch lead assembly.
Described magnetic clutch is a dry type monolithic magnetic clutch.
Described magnetic clutch is a dry-type multidisc electromagnetic clutch.
Described magnetic clutch is a wet type multi-disc electromagnetic clutch.
Described magnetic clutch is the slip type magnetic clutch.
The utility model installs the belt pulley of charged magnetic clutch additional on the pump shaft of conventional steering oil pump body, engage and the mode of operation that separates with the control power steerig pump through the magnetic clutch on the belt pulley.When deflector does not have handling maneuver, separate being connected of power steerig pump belt wheel and bearing, make power steerig pump termination work; In case and deflector engages oil pump belt wheel and oil pump bearing when handling maneuver is arranged, and power steerig pump is started working, and power steering is provided.The utility model can make power steerig pump need work perhaps to stop with turning to, and practices thrift driving engine kinetic energy, reduces oil consumption and emission of carbon-dioxide thereby reach; And power steerig pump uses present mature structure; Need not improve,, on prior art, be easy to repacking so total cost is lower.
Description of drawings
Fig. 1 is the utility model power steerig pump structural representation.
Among the figure: 1. power steerig pump body, 2. power-transfer clutch lead assembly, 3. belt pulley.
The specific embodiment
See also Fig. 1; As shown in the figure; Energy-saving automobile-used hydraulic power-assisted steering oil pump includes power steerig pump body 1 and is installed in the belt pulley 3 on the pump shaft, and this belt pulley 3 is the belt pulley of charged magnetic clutch, and magnetic clutch is electrically connected with the deflector controller through power-transfer clutch lead assembly 2.Magnetic clutch leans on joint that the break-make electricity of coil comes control clutch and separates; The magnetic clutch that the utility model adopts is dry type monolithic magnetic clutch, dry-type multidisc electromagnetic clutch, wet type multi-disc electromagnetic clutch or slip type magnetic clutch; Be the magnetic clutch of routine, do not mark the structure of magnetic clutch among the figure.The utlity model has following characteristics: 1) high-speed response: the reception and registration of torsion is very fast, can reach action easily.2) durability is strong: it is all right to dispel the heat, and has used premium-quality material, even high-frequency, high-octane use is also very durable.3) assembling is safeguarded easily: belong to the built-in pole winding silent oscillation of ball bearing of main shaft, also needn't not utilize carbon brush so need middle stamen not taken out, use simple.4) action really: use tabular shell fragment, though there have sharp pounding also can not produce to be loosening, durability is good.
