Abstract
The invention relates to a vehicle steering eccentric valve, which comprises a valve body as three-way valve. Wherein, the upper and lower ends of valve body are independently connected to the oil inlet tube and the oil outlet tube; the valve body can axially rotate between the oil inlet tube and the oil outlet tube; the side outlet of valve body is fixed with a sealing cover; the chamber of valve body is arranged with valve pin; a spring is arranged between the valve pin and the sealing cover; said valve pin can seal the oil line inside the valve body via the spring; the invention can be mounted on the tube from oil pump to the steering gear; when the rotation speed of wheel increases, the valve pin is drawn by eccentric force to move outwards and compress the spring to open the discharge oil outlet; and the oil from the oil pump will discharge pressure by the eccentric valve to reduce the oil flux that flows to the steering gear, therefore, the steering operation in high speed will be hard, to avoid deflection, and improve the driving safety.
Description
Technical field
The present invention relates to a kind of hydraulic control device of motor turning, particularly a kind of motor turning centrifugal valve.
Background technology
Automobile steering device can divide four kinds at present: machinery, hydraulic booster, electric-controlled hydraulic and electronic.Manual steering gear will lean on the direct veer dish of driver to overcome wheel steering resistance, hard steering; Hydraulic power steering gear overcomes the wheel steering resistance by hydraulic coupling, turn to lighter, but its power-assisted and oil pump have direct relation, the ubiquity pivot stud is effort and unstable problem but occurs when automobile when running at high speed.In order to solve the technology that unstable problem appears when the high speed steering in above-mentioned automobile mainly is to adopt electric-controlled hydraulic deflector and electric direction varying device.The electric-controlled hydraulic deflector has increased automatically controlled engine installation on the basis of hydraulic steering gear, to regulate the input torque on the bearing circle under the different moving velocitys, but need on original hydraulic steering gear basis, increase automatically controlled engine installation, the overall structure complexity, cost is higher.Electric direction varying device is by the cornering properties of program controlled motor power-assisted size need to obtain, but electric direction varying device is because thereby the exploitation high power DC electric machine is very difficult electric boosted little, makes it is used for relatively difficulty of autotruck.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of centrifugal valve that turns to that can effectively reduce hydraulic steering gear.
The technical solution adopted in the present invention is:
A kind of motor turning centrifugal valve, comprise valve body, described valve body is a triple valve, the upper and lower end of valve body is connected with oil outlet pipe with oil inlet respectively, valve body can axially rotatablely move between oil inlet and oil outlet pipe, and described valve body side exit is installed with seal cover cap, is provided with spool in the cavity of valve body, be provided with spring between spool and the seal cover cap, described spool has sealed the oil circuit in the valve body under the effect of spring;
Improve as technique scheme, described seal cover cap is provided with set screw, and set screw is passed with the seal cover cap spring and contacted; Be provided with the spacer sleeve of restriction spool shift length in the cavity of described valve body; Be respectively arranged with seal ring between the cavity inner wall of described spacer sleeve and set screw and valve body;
As further improvement in the technical proposal, be respectively arranged with seal ring and bearing between the upper and lower end of described valve body and oil inlet and the oil outlet pipe.
The invention has the beneficial effects as follows: the present invention is connected on oil pump to the pipeline of deflector, when vehicle wheel rotational speed increases, spool is motion and compression spring in the traction of centnifugal force and outwards, open the off-load hydraulic fluid port, make partial pressure oil that oil pump comes out by the centrifugal valve off-load, promptly reduces to the flow of the oil of deflector, thereby turning to when making high speed becomes heavy, can be not unstable, increase the safety of running at high speed.

The specific embodiment
With reference to Fig. 1; Fig. 2; Fig. 3; Fig. 4; a kind of motor turning centrifugal valve; comprise valve body 1; described valve body 1 is a triple valve; on the valve body 1; the lower end is connected with oil outlet pipe 3 with oil inlet 2 respectively; valve body 1 links to each other with rotation shaft of wheel by transmission device; described transmission device can be belt wheel or gear etc.; when transmission device rotates along with rotation shaft of wheel; valve body 1 can axially rotatablely move between oil inlet 2 and oil outlet pipe 3; in order to protect valve body 1 to be provided with protective case by vehicle frame; described valve body 1 side exit is by the seal cover cap 4 that has been threaded; be provided with spool 5 in valve body 1 cavity 11, be provided with spring 6 between spool 5 and the seal cover cap 4, described spool 5 has sealed the oil circuit 12 in the valve body 1 under the effect of spring 6.
The present invention is for the initial pressure of regulating spring 7, and described seal cover cap 4 is provided with set screw 7, and set screw 7 is passed with seal cover cap 4 springs 6 and contacted; In addition, be provided with the spacer sleeve 8 of restriction spool 5 shift lengths in described valve body 1 cavity 11; Better for the sealing effectiveness that makes this product, be respectively arranged with seal ring 71,81 between cavity 11 inwalls of described spacer sleeve 8 and set screw 7 and valve body 1.
This product is respectively arranged with seal ring 21,31 and bearing 22,32 between the upper and lower end of valve body 1 and oil inlet 2 and oil outlet pipe 3, it prevents that effectively fluid from leaking outside, but also reduces the rotational resistance of valve body 1.
Principle of work of the present invention is: the present invention is connected on oil pump to the pipeline of deflector, when vehicle wheel rotational speed increases, spool 1 is motion and compression spring 6 in the traction of centnifugal force and outwards, thereby open the off-load hydraulic fluid port, make partial pressure oil that oil pump comes out by the centrifugal valve off-load, promptly reduces to the flow of the oil of deflector, thereby turning to when making high speed becomes heavy, can be not unstable, increase the safety of running at high speed.
