Embodiment 1

[0055] Embodiment 1: The viscoelastic suspension mechanism that is used for the traveling mechanism of the large-scale crawler bulldozer of 300kW

[0056] For crawler bulldozers, the mass is 50,000kg (not including the mass of the scarifier), and the working environment temperature is between -40°C and 50°C.

[0057] In order to meet the cushioning performance of the viscoelastic shock absorber under the comprehensive working conditions of construction machinery, the rubber layer is designed with natural rubber. The total height of the rubber layer is designed according to its compression amount. In order to ensure that the bulldozer has good vibration damping effect and good working stability during operation, the maximum compression amount of the rubber layer should be its total height. 15% to 40% is more reasonable. The diameter of the elastic constrained layer 4 is 400mm and the height is 20mm; the diameter of the basic rubber layer 3 is 350mm and the height is 60mm; the d...

Embodiment 2

[0058] Example 2: Support assembly under unloading compartment for heavy dump truck

[0059] The upper half of the viscoelastic shock absorber is installed on the unloading carriage, and the lower half is installed on the frame. Elastic constrained layers 4 of metal materials are respectively used as connectors. The base rubber layer 3 is embedded with a φ0.5mm steel wire mesh; the middle rubber layer 2 and the contact rubber layer 1 are embedded with heat-conducting aluminum foil material wires.

Embodiment 3

[0060] Embodiment 3: The present invention can also be applied in the support of the foundation of large stamping machine tools

[0061] The upper half of the viscoelastic damper is installed on the base of a large press machine tool, and the lower half is installed on the foundation. Elastic constrained layers 4 of metal materials are respectively used as connectors. A φ2mm steel wire mesh is embedded in the base rubber layer 3; a φ0.5mm thermal conductive aluminum wire is embedded in the middle rubber layer 2 and the contact rubber layer 1.

Abstract

The present invention belongs to the field of vibration damper technology for suspension, in the concrete, it relates to a viscoelasticity vibration damper with sandwich. Said viscoelasticity vibration damper is formed from up-down symmetrical two groups of damping buffer pads, said damping buffer pad is composed of elastic constrained layer, basic rubber layer, intermediate rubber layer and contact rubber layer, in the basic rubber layer, intermediate rubber layer and contact rubber layer a metal filling material is added respectively, the central position of damping buffer pad is equipped with a metal supporting column, all the rubber layers are fixedly connected together.

Description

technical field [0001] The invention belongs to the technical field of shock absorbers for suspension devices, and in particular relates to a viscoelastic shock absorber with an interlayer. Background technique [0002] Known large-scale engineering vehicles have the advantages of high productivity and low unit operating cost, so engineering vehicles are developing towards large-scale and super-large. However, the increase in vehicle shape will inevitably cause more and more severe vibration and impact. With the increasingly stringent international environmental protection regulations and the fierce competition in international trade, many countries in the world have taken the vibration and noise indicators of off-road vehicles as technical barriers to restrict imports. Since most engineering vehicles operate on "non-road surfaces" and because of their operational requirements, rigid or semi-rigid suspension mechanisms are often used for vibration reduction. Although these ...
