Abstract
The invention provides a hanging damping valve which comprises a valve body, a valve rod, a bonnet and a pin, wherein the valve rod is inserted in a central hole of the valve body; an excircle of the valve rod and the central hole of the valve body are in clearance fit; the valve rod can do axial movement along the valve body; a lightening hole is formed in the center of the valve rod; a circular bead is arranged at the root of a conical surface of the valve rod; restoration damping holes uniformly distributed in the circumferential direction and compression discharging holes uniformly distributed in the circumferential direction are formed in the valve body; and the valve rod and the bonnet are in threaded connection, then, a through hole is formed, the pin is arranged in the through hole in a penetrating manner, and the pin and the end face joint part of the bonnet are firmly pivoted. A hydraulic damping valve provided by the invention is stable and reliable in working and can effectively improve the vibration attenuation capacity of a hydro-pneumatic spring as proved by practice.
Description
Technical field
The present invention relates to a kind of hang damping valve arrangement, belong to hydraulic system and road vehicle application field.
Background technology
The effect of liquid-springing valve be exactly back and forth flowed in damping hole by liquid, due between liquid internal molecule with
And the friction between molecule and hole wall, convert vibrational energy into heat energy and distribute, so as to the vibration of vehicle of decaying.Civilian goods car
Damping unit damper valve generally adopt choke valve slice structure, form is simple and has certain versatility, but practice have shown that
Then insufficient strength is applied on high motor-driven off-road vehicle, valve block fracture often occurs in Jing causes the situation of failure of apparatus.In addition at present
The liquid-springing valve generally existing overall volume of the manufacturing is larger, and construction is complicated, the defect such as quality is unstable.It is contemplated that
A kind of liquid-springing valve arrangement simple and reliable for structure is provided to solve above-mentioned technical problem.
The content of the invention
The present invention provides a kind of liquid-springing valve, including valve body, valve rod, bonnet and pin, and valve rod inserts the center of valve body
In hole, the cylindrical and valve body centre bore of valve rod is coordinated using gap, and valve rod can axially move along valve body；Valve rod center processes
The conical surface root for having lightening hole, valve rod is provided with fillet, is machined with circumferential uniform recovery damping hole uniform with circumferential on valve body
Compression discharge orifice；Valve rod is threaded connection first with bonnet, processes through hole afterwards, then pin is worn penetrates in through hole, pin and
The end face joint portion riveting jail of bonnet.
Liquid-springing valve provided by the present invention solves above-mentioned the deficiencies in the prior art well, stable and reliable in work,
By facts have proved the damping capacity that can effectively improve suspension.

Specific embodiment
Liquid-springing valve small volume according to the present invention, it is lightweight, it is stable and reliable in work.Its key component includes：
Valve body 2, valve rod 3, bonnet 4, pin 5.
Fig. 1 is the installation diagram of liquid-springing valve of the present invention, and part drawings of the Fig. 2 for valve body, Fig. 3 are the part drawing of valve rod.Will
In the centre bore of the insertion valve body 2 of valve rod 3, cylindrical the 13 of valve rod 3 is coordinated using gap with valve body centre bore 12, and valve rod can be along valve
Body centre bore does axial free movement, is machined with lightening hole 15 in the heart in addition in valve rod, mitigates valve rod with this and is being moved through
Suffered inertia impact in journey, 3 material of valve rod should be made using 40Cr structural alloy steels, to ensure which has enough work strong
Degree.Fillet 16 is provided with 14 root of the conical surface of valve rod 3 in order to reduce stress concentration, radius of corner should be greater than R2.5mm.Valve rod 3 with
Bonnet 4 is connected by screw thread 7 first, is processed through hole 8 afterwards, then is put on pin 5, it is to avoid pin occurs surface in installation process and draws
Wound and stress concentration, cause the phenomenon of fracture failure to occur.To guarantee that the diameter of enough intensity pins 5 should be greater than 3mm, in pin
The end face joint portion riveting jail of nail 5 and bonnet 4.Circumferential uniform recovery damping hole 10 and circumferential uniform pressure are machined with valve body 2
Contracting discharge orifice 9.
Fig. 4 is work sheet of the liquid-springing valve in compression travel, and Fig. 5 is work sheet of the liquid-springing valve in recovery stroke,
In figure, arrow represents the direction of main piston 6, floating piston 11 and liquid stream respectively, and its operation principle is as follows：
In the process of moving, the effect due to hanging flexible member usually requires that damper valve restores stroke Resistance Value to vehicle
It is big compared with compression travel, so that it is guaranteed that the riding comfort of occupant, and the construction featuress of the damper valve have complied fully with suspension damping
The use requirement of characteristic.
During compression travel, as the pressure Operating valve rod 3 of chamber will be in 2 points of position shown in Fig. 4, the conical surface 14 and valve body
From now part fluid will enter 11 side of floating piston by the gap for compressing discharge orifice 9 and between the conical surface 14 and valve body 2
Chamber, another part fluid will enter the chamber of 11 side of floating piston by restoring damping hole 10, due to damper valve throttleng surface
Product is larger, will produce less Resistance Value；When restoring stroke, valve rod 3 is in position shown in Fig. 5, valve rod 3 in the presence of fluid
On the conical surface 14 contact and compress with valve body 2, prevent fluid by compress discharge orifice 9, now fluid can only by restore damping
Realize throttling and producing larger damping force in hole 10.
Liquid-springing valve in the present invention adopts cone valve type linear sealing structure, the sensitivity to impurity pollution in fluid
Little, easy to manufacture, sealing property is excellent, with good promotional value.
It should be noted that skilled person can easily appreciate that, hydraulic lock-up valve involved in the present invention can
It is installed as described above on different types of vehicle, and in the spirit without departing from the present invention being defined by the following claims
In the case of scope, the change and change of various multi-forms can be carried out to the present invention.
