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:
一种液压式可变刚度螺旋弹簧，包括柱塞1，螺旋弹簧2，缸体3和液压油管4，所述柱塞1与所述缸体3分别位于所述弹簧的上下两端，所述螺旋弹簧2位于所述柱塞1与所述缸体3之间，所述液压油管4安装在所述缸体3的侧面。 A hydraulic variable stiffness coil spring, comprising a plunger 1, a coil spring 2, a cylinder 3 and a hydraulic oil pipe 4, the plunger 1 and the cylinder 3 are located at the upper and lower ends of the spring respectively, the The coil spring 2 is located between the plunger 1 and the cylinder 3 , and the hydraulic oil pipe 4 is installed on the side of the cylinder 3 .
优选的，所述螺旋弹簧2的弹簧丝为中空结构，且所述螺旋弹簧2的弹簧丝末端与所述柱塞1与所述缸体3配合形成的型腔连接在一起。 Preferably, the spring wire of the coil spring 2 is a hollow structure, and the end of the spring wire of the coil spring 2 is connected with the cavity formed by the cooperation of the plunger 1 and the cylinder body 3 .
进一步的，所述液压油管4外接液压油。 Further, the hydraulic oil pipe 4 is externally connected with hydraulic oil.
本发明的原理： Principle of the present invention:
螺旋弹簧2的弹簧丝为中空结构，螺旋弹簧2的弹簧丝末端与柱塞1与缸体3配合形成的型腔连接在一起，此外液压油管4可外接液压油。 The spring wire of the coil spring 2 is a hollow structure, and the end of the spring wire of the coil spring 2 is connected with the cavity formed by the cooperation of the plunger 1 and the cylinder body 3. In addition, the hydraulic oil pipe 4 can be externally connected with hydraulic oil.
该弹簧在工作时，弹簧受到挤压柱塞1和缸体3配合形成的液压腔体变小，内部的液压油通过螺旋弹簧2末端与缸体3的连接进入螺旋弹簧2内部，从而达到改变弹簧刚度的目的。此外通过液压油管4可与外部装置连接，实现对弹簧内部供油或者溢油，进而改变弹簧刚度。 When the spring is working, the spring is squeezed and the hydraulic cavity formed by the cooperation of the plunger 1 and the cylinder body 3 becomes smaller, and the internal hydraulic oil enters the interior of the coil spring 2 through the connection between the end of the coil spring 2 and the cylinder body 3, thereby achieving change purpose of spring stiffness. In addition, the hydraulic oil pipe 4 can be connected with an external device to realize oil supply or oil overflow to the inside of the spring, thereby changing the spring stiffness.
