Abstract

The invention discloses a hydraulic type rigidity-changeable spiral spring which comprises a plunger, a spiral spring body, a cylinder body and a hydraulic oil pipe, wherein the plunger and the cylinder body are positioned at the upper end and lower end of the spring respectively; the spiral spring body is positioned between the plunger and the cylinder body; the hydraulic oil pipe is mounted on the side face of the cylinder body. According to the invention, the hollow spiral spring body is connected with a hydraulic cavity and an external hydraulic device, so that when the spring is squeezed to work, the hydraulic oil distribution is changed to fulfill the purpose of changing the spring rigidity. The hydraulic type rigidity-changeable spiral spring is simple in structure, can ensure that the spring rigidity is changeable, and enables the basic structure of the spring not to change fundamentally.

Description

A kind of hydraulic type stiffness variable helical spring

Technical field

The invention belongs to mechanical field, be specifically related to a kind of hydraulic type stiffness variable helical spring.

Background technique

The helical spring of current stiffness variable mainly contains variable diameters stiffness variable spring and several spring superposition formation of elasticity height two kinds of modes, variable diameters stiffness variable spring existing problems are: one, spring diameter changes to cause and manufactures difficulty, manufacture cost promotes, two, in the place that diameter is less, when stressed larger time can contact, mutual superposition, when load is relatively large, causes diameter smaller part generation plastic deformation; The stiffness variable spring problem that several spring superposition of elasticity height is formed is: one, and the connection difficulty of different spring is very large, insecure, two, for the spring that diameter is less, when stressed larger time can contact, mutually superpose, when load is relatively large, cause diameter smaller part generation plastic deformation.

Summary of the invention

The object of the invention is to the above problem overcoming prior art existence, a kind of hydraulic type stiffness variable helical spring is provided, adopt better simply structure, helical spring and hydraulic pressure are combined, construct a kind of novel spring, this spring operationally rigidity is variable, and can improve as required or reduce rigidity.

For achieving the above object, reach above-mentioned technique effect, the present invention is achieved through the following technical solutions:

A kind of hydraulic type stiffness variable helical spring, comprises plunger, helical spring, cylinder body and hydraulic oil pipe, described plunger and described cylinder body lay respectively at the two ends up and down of described spring, and described helical spring is between described plunger and described cylinder body, and described hydraulic oil pipe is arranged on the side of described cylinder body.

Preferably, described helical spring spring thread is hollow structure, and described helical spring spring thread end coordinates the die cavity formed to link together with described plunger with described cylinder body.

Further, the external hydraulic oil of described hydraulic oil pipe.

The invention has the beneficial effects as follows:

The present invention by the helical spring of hollow and the connection of hydraulic pressure cavity, and with the connection of external hydraulic device, realize spring when being squeezed work, the distribution of hydraulic oil can change, thus reaches the object changing paralysed spring rate.This mechanism structure is simple, can ensure that spring rate is variable, and essence change does not occur the spring basic structure made again.

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 helical spring structural representation of hydraulic type stiffness variable of the present invention.

Number in the figure illustrates:

1, plunger, 2, helical spring, 3, cylinder body, 4, hydraulic oil pipe.

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 type stiffness variable helical spring, comprise plunger 1, helical spring 2, cylinder body 3 and hydraulic oil pipe 4, described plunger 1 and described cylinder body 3 lay respectively at the two ends up and down of described spring, described helical spring 2 is between described plunger 1 and described cylinder body 3, and described hydraulic oil pipe 4 is arranged on the side of described cylinder body 3.

Preferably, the spring thread of described helical spring 2 is hollow structure, and the spring thread end of described helical spring 2 coordinates the die cavity formed to link together with described plunger 1 with described cylinder body 3.

Further, the external hydraulic oil of described hydraulic oil pipe 4.

Principle of the present invention:

The spring thread of helical spring 2 is hollow structure, and the spring thread end of helical spring 2 coordinates the die cavity formed to link together with plunger 1 with cylinder body 3, and hydraulic oil pipe 4 can external hydraulic oil in addition.

Operationally, be squeezed plunger 1 and cylinder body 3 of spring coordinates the hydraulic chamber formed to diminish to this spring, and it is inner that inner hydraulic oil enters helical spring 2 by helical spring 2 end and the connection of cylinder body 3, thus reach the object of change spring rate.In addition can be connected with external means by hydraulic oil pipe 4, realize spring inner fuel feeding or oil spilling, and then change spring rate.

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.
