Embodiment 1

[0018] Such as figure 2 , Figure 4 As shown, the present invention comprises connecting plate, is divided into upper connecting plate 4, lower connecting plate 5, is vulcanized with rubber 6 between upper connecting plate 4, lower connecting plate 5, and rubber 6 is that the diameter of upper and lower ends is big, and middle diameter is little. One-piece hourglass-shaped structure, metal sheet 7 is inserted at the intersection of the upper part 10 and the lower part 11 of the rubber 6, which can achieve higher load capacity, fast rebound, excellent vibration damping, small creep, and impact resistance in a limited area , low natural frequency, etc., so that it can meet the use of more working conditions and occasions, and has a compact structure, low manufacturing cost, and can ensure the performance and life of the hourglass spring, and has good economic use value.

[0019] The middle part of the upper connecting plate 4 is provided with a protrusion 9 extending to the lo...

Embodiment 2

[0023] Such as image 3 , Figure 4 As shown, the rubber 6 is a solid structure, which also has a good damping effect.

Abstract

The invention provides a composite sandglass spring structure. Vibration reduction is good, the cost is low, the bearing capacity of a sandglass spring in a limited space can be improved, and application for more working conditions and on more occasions is achieved. The structure comprises connection plates and rubber vulcanized between the two connection plates, the rubber is of an integrated sandglass-shaped structure, the diameters of the upper and lower ends of the rubber are large, the diameter of the middle of the rubber is small, and metal sheets are inserted in the junction of the upper and lower portions of the rubber.

Description

technical field [0001] The invention relates to the technical field of railways and engineering machinery, in particular to a composite hourglass spring structure. Background technique [0002] At present, in the field of railways, in order to meet the requirements of vibration reduction, most of the secondary springs (springs between the carriage and the bogie) use hourglass springs, such as figure 1 As shown, the existing hourglass spring is vulcanized with a rubber body 3 between two connecting plates 1 and 2. The rubber body 3 has a structure with a large diameter at the upper end and a small diameter at the lower end. For industrial or other non-highway applications, due to the low load capacity of a single hourglass spring, it cannot meet some projects with high load requirements, so it is necessary to configure multiple hourglass springs to meet the load requirements, which will lead to increased cost accumulation Moreover, the higher requirements for floor space can...
