Abstract
Make the ancon joint, the steering knuckle hydraulic actuator of rotating particularly, it has the ring guide channel that is made of jointly actuator lower body 2 and upper body 1 and transmission ring 3, at least one piston (4) can move sealedly at the ring guide channel, and be fixed on the transmission ring (3), and at least one fixed piston (5) is fixed on the lower body (2).This hydraulic actuator allows relative its theoretical axis in ancon joint to bend, and can not produce additional power between this actuator and ancon joint.
Description
The present invention relates to one make the ancon joint, such as steering knuckle, the hydraulic actuator of in less than 360 ° scope, rotating.
In the prior art, making the actuator of the ancon joint rotation of the above-mentioned type is to have straight-line mechanical transmission or hydraulic actuator.The straight line motion of such actuator is given the ancon joint by lever transmission, and the result makes the rotational motion in ancon joint depend on the state in ancon joint, is finished by variable force.
In addition, the known actuator of above-mentioned pattern has one and is fixedly coupled a little on the ancon joint.Like this, when the known actuator of above-mentioned pattern with the ancon joint, when particularly being connected, can produce fault with steering knuckle.Because stressed work the in ancon joint the bending of deviation theory central axis may take place at the time spent, and during because of temperature variation, can cause that also it is flexible.
Then can avoid above-mentioned those shortcomings according to hydraulic actuator of the present invention.This is because the point of action of hydraulic actuator of the present invention is changeless to the distance of ancon articulation center axis.In addition, hydraulic actuator of the present invention, the axial direction in the ancon joint, its tie point is movably, and allows relative its theoretical axis in ancon joint to bend, and can not produce additional power between this actuator and ancon joint.
Hydraulic actuator of the present invention has obtained above-mentioned those advantages by the feature of narrating in the claims.
According to hydraulic actuator of the present invention, use two pistons, one fixing, one removable, can make the ancon joint do rotation greater than 300 °.If the steering knuckle on the actuating ship, then every type piston need be with two.To normal direction of rotation is 2 * 35 ° relatively large ship, and every type piston uses three and is advisable.
Fig. 1 is the axonometric drawing according to hydraulic actuator of the present invention, for the sake of simplicity, analyses and observe at different positions;
Fig. 2 is the horizontal projection according to hydraulic actuator of the present invention, has wherein cutd open half of upper body part;
Fig. 3 is the sectional drawing that passes through piston according to hydraulic actuator of the present invention;
Fig. 4 is the sectional drawing of cutting open along IV-IV among Fig. 2;
Fig. 5 has roughly showed the actuator that has hydraulic part.
Constitute garden annular guide channel jointly by actuator lower body 2 and upper body 1 and transmission ring 3, wherein transmission ring 3 is arranged in the inboard in annular guide channel garden week, garden.It is around an ancon joint, and arranges roughly that with it in the present embodiment, the ancon joint is a steering knuckle 8 with meeting at right angles.
Two pistons 5 radially relatively are fixed on the lower body 2 each other, and two pistons 4 that are fixed on the transmission ring 3 also are radially relatively to be provided with each other, and place between two pistons 5 that are fixed on the lower body 2.All pistons all are equipped with Sealing 11 and fit hermetically with garden annular guide channel at its two ends.
Upper body 1 is fixedly connected on the lower body 2, and transmission ring 3 can be relative to the upper body 1 and lower body 2 rotate hermetically.Therefore, be fixed on the piston 4 on the transmission ring 3, also can in the annular guide channel of garden, move relative to the piston 5 that is fixed on the lower body 2.
Upper body 1 and lower body 2 all have two grooves separately, and these grooves constitute the passage 9,10 of hydraulic fluid jointly.An outlet 13 is arranged near the end of each piston 5 that is fixed on the lower body 2, is provided with a connecting passage 12 at path 10 with between exporting 13.And between the outlet of the same piston the other end and passage 9, be provided with a corresponding connecting passage.Correspondingly be arranged on the connection set on the lower body 2, respectively hydraulic fluid inputed or outputed through passage 9 and 10.
In each bar connecting passage 12, a control valve 14 is set.Therefore, can passage 9 or 10 and garden annular guide channel between set up respectively and link, perhaps at garden annular guide channel be arranged on hydraulic fluid in the lower body 2 and store to set up between the case 15 and link.The structure of control valve 14, on demand, such as certain part at garden annular guide channel break down, when leaking, pressure that can minimizing garden certain part of annular guide channel.
When to any one in the described passage, such as path 10, when exerting pressure, hydraulic fluid just flows in the garden annular guide channel in two spaces that radially are oppositely arranged by connecting passage 12, outlet 13, the piston 4 that promotes simultaneously to be fixed on the transmission ring 3 leaves corresponding piston 5, and at the hydraulic fluid of piston 5 the other ends, outlet, connecting passage by corresponding setting are discharged in the passage 9, and then turn back to hydraulic fluid and store in the case 15, this case links to each other with hydraulic mechanism.The result makes transmission ring 3 move relative to lower body 2, thereby also just promotes two radially positioned opposite, and the pin 7 that is connected with steering knuckle 8 moves.Pin 7 is being installed in the support pads 17 relative to the mode that support pads 17 rotates.Each support pads 17 all so that its can be arranged on relative to the mode that transmission ring 3 axial directions move between two guiding elements 18.Like this, when temperature variation, can allow steering knuckle 8 to produce and shrink or extension.
In these the disclosed embodiments, pin 7 is fixed on the rotor 6, and rotor 6 is connected with steering knuckle 8 rigidly.This by starting passage 9 or 10, can make steering knuckle 8 rotate at both direction according to the most preferred embodiment of hydraulic actuator of the present invention.Therefore, no matter be owing to temperature variation makes pin 7 length change, still owing to the effect of external force, and make the knuckle bending and leave theoretical axis steering knuckle or rudder, all can not between pin 7 and transmission ring 3, produce additional power.Actuator of the present invention had both made tiltingly with respect to steering knuckle, also will can not influence the relation between this actuator and the steering knuckle.But the flexible of rotor 6 can be admitted by support pads 17.
