Embodiment 1

[0047] Embodiment 1: as Figure 4 to Figure 7 As shown, the multi-segment combination close-to-type rubber profile includes a side straight segment 15, an inner concave arc segment 16, 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-5 is connected with an end of the concave arc-shaped line segment-6, the other end of the concave arc-shaped line segment-6 is connected with an end of the convex arc-shaped line segment 7, and the other end of the convex arc-shaped line segment 7 One end is connected with one end of the inner concave arc line segment two 8, and the other end of the inner concave arc line segment two 8 is connected with one end of the side straight line segment two 9. The circle centers of the concave arc line segment 1 6 and the concave arc line segment 2 8 are located outside the rubber profile, and the circle centers of the convex arc line segment 7 are located inside the r...

Embodiment 2

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

[0063] When there is also a side straight section three 10 between the convex arc line segment 7 and the concave arc line segment two 8 in the rubber profile at the lower end, in the rubber profile at the lower end, the side line segment one 5 and the side line segment one 5 The included angle between the second straight line segment 9 is set to k, the included angle between the second straight line segment 9 at the side portion and the third straight line segment 10 at the side portion is set to j, then the included angle k>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 at 5-15 degrees, and the radius of the convex ar...

Embodiment 3

[0065] Embodiment 3: Compared with Embodiment 1, the difference lies in that a side straight segment 3 is 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 rubber surface of a conical spring from wrinkling and realizing variable stiffness and a conical spring, wherein the method is to set the upper rubber surface and the lower rubber surface of each rubber body in the conical spring to multiple The combination of line segments close to the rubber profile, during the compression process of the conical spring, makes the two sides of the upper rubber profile of each rubber body gradually close together and makes the lower rubber of each rubber body The two sides of the profile can also be gradually brought closer to fit together. The invention can solve the problem of wrinkles on the rubber surface of the conical spring, prevent the rubber surface of the conical spring from being folded and cracked due to compression, improve the fatigue life of the conical spring and realize the vertical variable stiffness characteristic of the conical spring, and improve the product reliability.

Description

technical field [0001] The invention relates to an improved method of a conical spring and the improved conical spring, in particular to a method for preventing the rubber surface of the conical spring from wrinkling and realizing variable stiffness and the conical spring, belonging to the technical field of elastic vibration reduction. Background technique [0002] The conical spring is a commonly used rubber-metal composite vibration and noise reduction component, mainly referring to a metal-rubber combined spring with a vibration-damping effect, and both the metal and the rubber form a conical structure. Installed on the car body of the primary suspension and secondary suspension of the rolling stock, the main function is to bear the load of the car body and 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 vehicle body, ensures the height between the vehicle body and the gro...
