Abstract
The invention discloses a hydraulic spring which comprises a plunger, a leaf spring, hydraulic oil and a cylinder body, wherein the plunger is connected with the cylinder body; two ends of the leaf spring are connected with the plunger and the cylinder body respectively; the plunger is filled with the hydraulic oil; the leaf spring and the cylinder body form an enclosed space. According to the invention, the leaf spring is adopted to construct a volume-changeable hydraulic cavity, and several oil outlet and return holes are formed in the bottom of the cylinder body, so that the hydraulic oil still has better elasticity when being squeezed. The hydraulic spring is simple in structure, can ensure the elastic property during working and also can ensure that the spring is not damaged or cracked in case of overload.
Description
Technical field
The invention belongs to mechanical field, be specifically related to a kind of hydraulic spring grease cup.
Background technique
At present a lot of for spring kind, have metal spring and nonmetal spring etc., metal spring has and is divided into helical spring, dish spring and leaf spring etc., and nonmetal spring is mainly block rubber etc., also has some pure hydraulic type dampers, also can be used as spring.For non-hydraulic formula spring, the helical spring of such as metal species, and the block rubber etc. of non-metal kind, distortion operationally by self provides elastic force, this spring subject matter is the bearing capacity being greater than spring when load, spring is stressed excessive and damage and even rupture because of it, directly produces danger.Larger load can be born for pure hydraulic type damper, can ensure in the case of an overload not destroy, but the elasticity that the spring of this pure hydraulic type presents when being squeezed due to hydraulic oil reduces gradually along with the increase of pressure, and integral, flexible performance is bad.
Summary of the invention
The object of the invention is to the above problem overcoming prior art existence, a kind of hydraulic spring grease cup is provided, adopt simple structure, realize the perfect combination of metal spring and hydraulic spring grease cup, construct a kind of novel spring, namely this spring operationally has good elasticity capacity, can ensure that again in overload be that spring has very high intensity, not fragile.
For achieving the above object, reach above-mentioned technique effect, the present invention is achieved through the following technical solutions:
A kind of hydraulic spring grease cup, comprises plunger, spring sheet, hydraulic oil and cylinder body, described plunger is connected with described cylinder body, and the two ends of described spring sheet are connected with described plunger and described cylinder body respectively, described hydraulic oil is filled in by described plunger, in the confined space of described spring sheet and described cylinder body composition.
Further, described spring sheet has two.
Preferably, described cylinder base is provided with out spill port.
The invention has the beneficial effects as follows:
The hydraulic pressure cavity of the present invention by utilizing spring sheet to construct a variable-volume, and cylinder base several go out spill port, realize hydraulic oil, when being squeezed, still there is good elasticity.This mechanism structure is simple, can ensure elastic performance during spring works, and when can ensure again to transship, spring can not damage or break.
Above-mentioned explanation is only the general introduction of technical solution of the present invention, in order to better understand technological means of the present invention, and can be implemented according to the content of specification, coordinates accompanying drawing to be described in detail as follows below with preferred embodiment of the present invention.The specific embodiment of the present invention is provided in detail by following examples and accompanying drawing thereof.
Accompanying drawing explanation
accompanying drawing described herein is used to provide a further understanding of the present invention, and form a application's part, schematic description and description of the present invention, for explaining the present invention, does not form inappropriate limitation of the present invention.In the accompanying drawings:
Fig. 1 is the structural representation of hydraulic spring grease cup of the present invention.
Number in the figure illustrates:
1, plunger, 2, spring sheet, 3, hydraulic oil, 4, cylinder body.
Embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments in detail, structural feature of the present invention and technology implementation process are described in detail:
A kind of hydraulic spring grease cup, comprise plunger 1, spring sheet 2, hydraulic oil 3 and cylinder body 4, described plunger 1 is connected with described cylinder body 4, the two ends of described spring sheet 2 are connected with described plunger 1 and described cylinder body 4 respectively, and described hydraulic oil 3 is filled in by described plunger 1, in the confined space that described spring sheet 2 and described cylinder body 4 form.
Further, described spring sheet 2 has two.
Preferably, spill port is provided with out bottom described cylinder body 4.
Principle of the present invention:
Utilize spring sheet 2 to construct the hydraulic pressure cavity of a variable-volume, and bottom cylinder body 4 several go out spill port, realize hydraulic oil, when being squeezed, still there is good elasticity.
This spring is when the initial stage of work is little by load, elastic force is provided primarily of spring sheet 2, when load increases gradually, plunger 1 can move down, elastic force and 2, the spring of hydraulic oil play a role jointly, now hydraulic oil can overflow certain hydraulic oil by the spill port that goes out of cylinder body 4 bottom toward cylinder body 4 outside, suitably carry out step-down, solve the problem that when hydraulic oil is squeezed, elasticity can reduce, when load continues to increase, when even transshipping, hydraulic oil is full of whole cavity, spring sheet 2 is not compressive state but resilience even stretches, guarantee can not squeezedly crush, moreover utilize the crushing resistance of hydraulic oil, ensure that Monolithic spring can not be damaged.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
