Abstract
The invention discloses a large hydraulic steering oil tank and belongs to the field of a hydraulic oil tank. The large hydraulic steering oil tank comprises a piston rod, a cylinder and a shaft sleeve, wherein the cylinder coaxially sleeves the piston rod; a piston and two stroke sleeves sleeve the piston rod; the piston is fixedly arranged on the piston rod in a welding way; the stroke sleeves are arranged on the two sides of the piston; screw threads are formed on the outer wall of the shaft sleeve; the piston rod is fixed in the cylinder through the screw threads; the piston and the stroke sleeves are sealed in the cylinder. Due to the fact that the piston and the piston rod are fixed in a welding way, the working reliability of the piston rod in a high-oil pressure environment is improved; one stroke sleeve is respectively arranged on each of the two sides of the piston, the stroke of the movement of the piston rod can be effectively limited, and the service life of the steering oil tank is prolonged; due to the fact that the used shaft sleeve has a fixing effect and a sealing effect, the whole oil tank is simple in structure and convenient to mount.
Description
technical field
The present invention relates to a kind of large hydraulic steering cylinder, it belongs to hydraulic jack field.
Background technique
Hydraulic jack is widely used in engineering machinery, and wherein steering hydraulic oil cylinder is generally applied on the engineering vehicles such as fork truck, for Vehicular turn.Steering cylinder in the market, between its piston and piston rod, conventionally adopt steel ball and Cock screw to fix, this means of fixation is for small-sized steering cylinder, assembling is trouble not very, but the parts of large-scale steering cylinder are excessive, just installing has been not easily, and large-scale steering cylinder oil pressure is larger, Cock screw has loosening possibility after long-time use, makes piston no longer firm; And the piston rod of general steering cylinder does not all have special range controlling mechanism, this has caused piston directly and axle sleeve collision, easily damages piston face; General steering cylinder needs multiple part sealed cylinder blocks such as cylinder cap, axle sleeve, has caused efficiency of assembling not high.
Summary of the invention
Technical problem to be solved by this invention is: a kind of large hydraulic steering cylinder is provided, and it has solved the problem more fixedly securing between the piston rod of large hydraulic steering cylinder and piston, has also solved the control piston throw of lever, has simplified the problems such as part-structure.
Technical problem to be solved by this invention takes following technological scheme to realize:
A kind of large hydraulic steering cylinder, it comprises piston rod, cylinder barrel, axle sleeve, described cylinder barrel concentric is enclosed within on piston rod, described upper cover of piston rod has a piston and two stroke covers, wherein piston is fixed on piston rod by welding manner, and stroke is set on piston both sides, and described axle sleeve outer wall is provided with screw thread, by screw thread, piston rod is fixed in cylinder barrel, and piston and stroke cover are sealed in cylinder barrel.
As preferred embodiment, between described axle sleeve and piston rod, ecto-entad is provided with dust ring, shaft seal and steel back lining successively.
As preferred embodiment, between described cylinder barrel and axle sleeve, be provided with successively from outside to inside O RunddichtringO and supporting ring.
As preferred embodiment, between described piston and cylinder barrel, be provided with O RunddichtringO and dual-supporting ring, dual-supporting ring is distributed in O RunddichtringO both sides.
The invention has the beneficial effects as follows: piston and piston rod are fixed by welding manner, promoted the reliability of high oil pressure environment lower piston rod work; A stroke cover is respectively set, the effectively stroke of limited piston bar motion, the working life of prolongation steering cylinder on piston both sides; The axle sleeve using has been taken into account the effect of fixing and sealing, and whole cylinder structure is simple, easy for installation.

Fig. 2 is shaft sleeve part separation structure schematic diagram of the present invention;
Fig. 3 is the structural representation of piston of the present invention, stroke cover part.
Embodiment
For to technological means of the present invention, creation characteristic, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of large hydraulic steering cylinder, it comprises piston rod 1, cylinder barrel 2, axle sleeve 3, cylinder barrel 2 concentrics are enclosed within on piston rod 1, and on piston rod 1, cover has a piston 4 and two stroke covers 5, and wherein piston 4 is fixed on piston rod 1 by welding manner, stroke cover 5 is arranged on piston 4 both sides, axle sleeve 3 outer walls are provided with screw thread, by screw thread, piston rod 1 is fixed in cylinder barrel 2, and piston 4 and stroke cover 5 are sealed in cylinder barrel 2.Between axle sleeve 3 and piston rod 1, ecto-entad is provided with dust ring 6, shaft seal 7 and steel back lining 8 successively.Between cylinder barrel 2 and axle sleeve 3, be provided with successively from outside to inside O RunddichtringO 9 and supporting ring 10.Between piston 4 and cylinder barrel 2, be provided with O RunddichtringO 9 and dual-supporting ring 10, dual-supporting ring 10 is distributed in O RunddichtringO 9 both sides.
Between piston rod 1 and piston 4, fix by welding manner, strengthened both constant intensities on the one hand, improved piston 4 functional reliabilities, simplified on the other hand number of spare parts and the installation time of assembling piston 4.But higher to welding required precision, improve by automation or semi-automatic welding manner.
Stroke cover 5 is set respectively in piston 4 both sides of piston rod 1, the effectively stroke of the side-to-side movement of limited piston bar 1, large hydraulic steering cylinder oil pressure is larger, need to overlap 5 with stroke and protect the complete and injury-free of all parts in steering cylinder.
Axle sleeve 3 combines the function of cylinder cap and the cylinder sleeve of general oil cylinder, can play the effect of fixed piston rod 1, piston 4 and stroke cover 5 can be sealed in to cylinder barrel 2 inside again, and further reduce Assembly part quantity, save installation time, improved working efficiency.
More than show and described basic principle of the present invention and major character and advantage of the present invention.The technician of the industry should understand, and the present invention is not restricted to the described embodiments, and without departing from the spirit and scope of the present invention, the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
