Embodiment 1

[0047] Example 1: as Figure 4 to Figure 7 As shown, the multi-segment combined close-fitting rubber profile includes a side straight segment 1 5, an inner concave arc segment 1 6, an outer convex arc segment 7, an inner concave arc segment 2 8 and a side straight segment 2 9 One end of the side straight line segment one 5 is connected with one end of the inner concave arc line segment one 6, the other end of the inner concave arc line segment one 6 is connected with one end of the outer convex arc line segment 7, and the other end of the outer convex arc line segment 7 is connected. One end is connected with one end of the concave arc line segment 2 8 , and the other end of the concave arc line segment 2 8 is connected with one end of the side straight line segment 2 9 . The center of the inner concave arc line segment 1 6 and the inner concave arc line segment 2 8 is located outside the rubber profile, and the circle center of the outer convex arc line segment 7 is located i...

Embodiment 2

[0062] Example 2: as Figure 17 As shown, compared with Embodiment 1, the difference is that a side straight line segment 3 10 is also provided between the convex arc line segment 7 and the concave arc line segment two 8 in the lower rubber profile.

[0063] When a side straight line segment 3 10 is further provided between the convex arc line segment 7 and the concave arc line segment 2 8 in the lower end rubber profile, in the lower end rubber profile, the side straight line segment 1 5 and the side The included angle between the second straight line segment 9 is set as k, and the included angle between the second straight side segment 9 and the third straight side segment 10 is set as j, then the included angle k>the included angle j. In this way, problems such as "wrinkle" deformation and stress concentration can be further avoided.

[0064]In this embodiment, the included angle j is set to be 5-15 degrees, and the radius of the convex arc-shaped line segment 7 in the low...

Embodiment 3

[0065] Example 3: Compared with Example 1, the difference is that a side straight line segment 3 is also provided between the convex arc line segment and the concave arc line segment 2 in the upper rubber profile.

Abstract

The invention discloses a method for preventing the conical spring rubber profile from wrinkling and achieving a variable stiffness and a conical spring. The rubber profile at the upper end and the rubber profile at the lower end of each rubber body in the conical spring are respectively arranged into a multi-line-line combined close-type rubber profile, so that the two side edges of the rubber profile at the upper end of each rubber body can be gradually close to each other in the compression process of the conical spring, so that the two side edges of the rubber profile at the lower end of each rubber body can be gradually close to each other. According to the conical spring rubber profile, the problem that the conical spring rubber profile is wrinkled can be solved, the conical spring rubber profile can be prevented from being cracked due to compression due to compression, the fatigue life of the conical spring is prolonged, the vertical variable stiffness characteristic of the conical spring is realized, and the reliability of the product is improved.

Description

technical field [0001] The invention relates to an improved method for a conical spring and the improved conical spring, in particular to a method and a conical spring for preventing the wrinkling of the rubber profile of the conical spring and realizing variable stiffness and the conical spring, belonging to the technical field of elastic vibration reduction. Background technique [0002] Conical spring is a commonly used rubber-metal composite vibration and noise reduction element, mainly refers to a spring with vibration damping effect combined with metal and rubber. Both metal and rubber have a conical structure. Installed on the body of the primary suspension and secondary suspension of the rolling stock, it is mainly used to bear the load of the body and the frame. The application principle is: when the vehicle is running normally, the conical spring not only bears the vertical load of the frame and the body, but also bears the longitudinal force in the direction of tr...
