Description

一种液压弹簧a hydraulic spring

技术领域 technical field

本发明属于机械领域,具体涉及一种液压弹簧。 The invention belongs to the field of machinery, and in particular relates to a hydraulic spring.

背景技术 Background technique

    目前对于弹簧种类很多,有金属弹簧及非金属弹簧等,金属弹簧有分为螺旋弹簧、碟弹簧和板弹簧等,非金属弹簧主要为橡胶块等,还有一些纯液压式阻尼器,也可用作弹簧。对于非液压式弹簧,例如金属类的螺旋弹簧,以及非金属类的橡胶块等,在工作时靠自身的变形提供弹力,这种弹簧主要问题是当载荷大于弹簧的承载能力是,弹簧因其受力过大而损坏甚至断裂,直接产生危险。对于纯液压式阻尼器能够承受较大载荷,在过载情况下能保证不破坏,但是这种纯液压式的弹簧由于液压油在受到挤压时所呈现的弹性随着压力的增大是逐渐降低的,整体弹性性能不好。 At present, there are many types of springs, such as metal springs and non-metal springs. Metal springs are divided into coil springs, disc springs and leaf springs. Non-metal springs are mainly rubber blocks, etc. There are also some pure hydraulic dampers, which can also be used.

Damage or even breakage due to excessive force will directly cause danger. For the pure hydraulic damper, it can withstand a large load, and it can guarantee that it will not be damaged under overload conditions. However, the elasticity of this pure hydraulic spring will gradually decrease with the increase of pressure due to the elasticity of the hydraulic oil when it is squeezed. Yes, the overall elastic performance is not good.

具体实施方式 Detailed ways

下面将参考附图并结合实施例,来详述本发明的结构特点及技术实施过程: Below with reference to accompanying drawing and in conjunction with embodiment, structural feature and technical implementation process of the present invention are described in detail:

    一种液压弹簧,包括柱塞1,弹簧片2,液压油3和缸体4,所述柱塞1与所述缸体4连接,所述弹簧片2的两端分别与所述柱塞1和所述缸体4连接,所述液压油3填充于由所述柱塞1,所述弹簧片2和所述缸体4组成的密闭空间内。 A hydraulic spring, comprising a plunger 1, a spring leaf 2, hydraulic oil 3 and a cylinder body 4, the plunger 1 is connected to the cylinder body 4, and the two ends of the spring leaf 2 are respectively connected to the plunger 1 It is connected with the cylinder body 4 , and the hydraulic oil 3 is filled in the closed space formed by the plunger 1 , the spring leaf 2 and the cylinder body 4 .

    进一步的,所述弹簧片2有两个。 Further, there are two spring sheets 2.

优选的,所述缸体4底部设有出回油孔。 Preferably, an oil outlet and return hole is provided at the bottom of the cylinder body 4 .

本发明的原理: Principle of the present invention:

 利用弹簧片2构造一个体积可变的液压空腔,以及缸体4底部几个出回油孔,实现液压油在受到挤压时仍具有较好的弹性。 A volume-variable hydraulic cavity is constructed by using the spring plate 2, and several oil outlet and return holes at the bottom of the cylinder body 4, so that the hydraulic oil still has good elasticity when squeezed.

该弹簧在工作初期受载荷不大时,主要由弹簧片2提供弹力,当载荷逐渐增大时,柱塞1会往下移动,液压油的弹力和弹簧2片共同起到作用,此时液压油会通过缸体4下部的出回油孔往缸体4外部溢出一定的液压油,适当进行降压,解决了液压油受挤压时弹性会降低的问题,当载荷继续增大时,甚至过载时,液压油充满整个空腔,弹簧片2不是压缩状态而是回弹甚至拉伸,保证不会被挤压破了,再者利用液压油的抗压性,保证整体弹簧不会被损坏。 When the spring is under a small load at the beginning of work, the elastic force is mainly provided by the spring sheet 2. When the load gradually increases, the plunger 1 will move down, and the elastic force of the hydraulic oil and the two spring sheets work together. At this time, the hydraulic pressure The oil will overflow a certain amount of hydraulic oil to the outside of the cylinder 4 through the oil outlet and return hole at the lower part of the cylinder 4, and the pressure will be reduced appropriately, which solves the problem that the elasticity of the hydraulic oil will decrease when the hydraulic oil is squeezed. When the load continues to increase, even When overloaded, the hydraulic oil fills the entire cavity, and the spring leaf 2 is not in a compressed state but rebounds or even stretches to ensure that it will not be squeezed and broken. Furthermore, the pressure resistance of the hydraulic oil is used to ensure that the entire spring will not be damaged. .

以上所述仅为本发明的优选实施例而已,并不用于限制本发明,对于本领域的技术人员来说,本发明可以有各种更改和变化。凡在本发明的精神和原则之内,所作的任何修改、等同替换、改进等,均应包含在本发明的保护范围之内。 The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and changes. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
