Abstract
The invention relates to a vehicle steering eccentric hydraulic valve, which comprises a valve body, a valve pin, an eccentric block and a spring. Wherein, the valve body is hollow with a chamber; the valve pin and the eccentric block are inside the chamber to be connected by connecting axle; the spring is connected to the valve pin and the valve body; the valve wall between the valve pin and the eccentric block is arranged with through oil tube that rotationally connected to the oil inlet tube and the oil outlet tube; the valve body via transmission device is connected to the rotation shaft of wheel; the valve body will rotates more quickly along with the higher speed of vehicle speed, and the eccentric block will draw the valve pin to generate larger displacement, the flux of hydraulic oil will be reduced to prevent the defection of steering wheel; but if the vehicle speed is slow, the displacement of valve pin will be small, and the flux of hydraulic oil will be increased and the steering wheel can steer easily. The invention can be improved based on former hydraulic steering device, with lower cost.
Description
Technical field
The present invention relates to a kind of hydraulic control device of motor turning.Especially a kind of centrifugal hydraulic valve for automobile steering.
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.The technology that occurs unstable problem for above-mentioned solution automobile when the high speed steering 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 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.Electric direction varying device is by the cornering properties of program controlled motor power-assisted size need to obtain, but need increase automatically controlled engine installation on original hydraulic steering gear basis, the overall structure complexity, and cost is higher.
Summary of the invention
The object of the present invention is to provide a kind of centrifugal hydraulic valve for automobile steering, install additional on original hydraulic steering gear and get final product, can effectively reduce the unstable problem of hydraulic steering gear, and simple, cheap for manufacturing cost.
The present invention realizes above-mentioned purpose like this:
Centrifugal hydraulic valve for automobile steering is characterized in that comprising valve body, spool, centrifugal and spring, and valve body hollow forms cavity, spool with centrifugal to be arranged at valve cavity interior and be connected by adapter shaft; Spring links to each other with valve body with spool respectively; Valve body wall between spool and centrifugal is provided with the oil pipe of perforation, links to each other with oil inlet and oil outlet pipe are rotatable respectively; Valve body via transmission device links to each other with rotation shaft of wheel.
The invention has the beneficial effects as follows: valve body via transmission device links to each other with rotation shaft of wheel, along with rotation shaft of wheel is rotated, centrifugal under the traction of centnifugal force to by adapter shaft traction spool compression spring, thereby make the flow of spool hydraulic oil inside the Pass oil pipe motion control has; When the speed of a motor vehicle fast more, the valve body rotative speed is also fast more, the displacement of centrifugal traction spool generation is just big more, just spool stops up oil pipe gradually, thereby hydraulic fluid flow rate reduces the unstable problem prevent that the bearing circle driving torque is less and to cause, if but the speed of a motor vehicle is slower, and spool displacement is just more little, hydraulic fluid flow rate increases, and bearing circle turns to easily; The present invention is installed additional on original hydraulic steering gear and is got final product, and can effectively reduce the unstable problem of hydraulic steering gear, and simple, cheap for manufacturing cost.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples:
Fig. 1 is a broken away view of the present invention;
Fig. 2 is a section-drawing of the present invention.
The specific embodiment
With reference to Fig. 1, Fig. 2, centrifugal hydraulic valve for automobile steering comprises valve body 1, spool 2, centrifugal 3 and spring 4, and valve body 1 hollow forms cavity, spool 2 with centrifugal 3 to be arranged at valve body 1 cavity interior and be connected by adapter shaft 5.Spring 4 links to each other with valve body 1 with spool 2 respectively.Valve body 1 wall between spool 2 and centrifugal 3 is provided with the oil pipe 6 of perforation, respectively with oil inlet 7 and 8 rotatable linking to each other of oil outlet pipe.Valve body 1 links to each other with rotation shaft of wheel by transmission device.Valve body 1 links to each other with rotation shaft of wheel by transmission device, and along with rotation shaft of wheel is rotated, centrifugal 3 is drawn spools 2 compression springs 4 to passing through adapter shaft 5 under the traction of centnifugal force, thereby makes the flow of spool 2 hydraulic oil inside the Pass oil pipe 7 motion controls have.When the speed of a motor vehicle fast more, valve body 1 rotative speed is also fast more, the displacement of centrifugal 3 traction spool 2 generations is just big more, just spool 2 stops up oil pipe 7 gradually, thereby hydraulic fluid flow rate reduces the unstable problem prevent that the bearing circle driving torque is too small and to cause, if but the speed of a motor vehicle is slower, and spool 2 displacements are just more little, hydraulic fluid flow rate increases, and bearing circle turns to easily.
Rock in order to prevent that centrifugal 3 and spool 2 from producing when valve body 1 cavity moves, also be provided with the guide 9 of band centre hole in valve body 1 cavity, connect spool 2 and pass this centre hole with centrifugal 3 adapter shaft 5, spring 4 links to each other with guide 9 with spool 2 respectively.Adapter shaft 5 can produce axial motion following of the guiding of centre hole, and simultaneously guide 9 can prevent that also hydraulic oil from entering in centrifugal 3 residing cavity.
In addition, for the ease of the assembling of centrifugal hydraulic valve, valve body 1 cavity is uncovered to centrifugal 3-end.Spool 2, spring 4, adapter shaft 5 and centrifugal 3 can assemble by uncovered.Assembling finishes, and has the seal cover cap 10 should uncovered sealing, prevents that dust etc. from entering in the valve body 1.
