Embodiment 1

[0038] The combined buffer of polymer elastic elements and metal friction elements is a square shell, the inner wall of the shell 1 is a plane wall, the wedge-shaped block mounting body 4 is a square body, and the outer surface of the square body 2 has 4 symmetrical wedge-shaped grooves and 4 right-angled trapezoidal Body wedge block 5 is matched with the wedge-shaped groove of wedge-shaped block mounting body 4, and the wedge-shaped angle of wedge-shaped groove and wedge-shaped block, namely, the angle between the inclined plane and the horizontal plane is 50°. Seven polymer elastic elements 3 and eight metal spacers 2 Alternately installed on the mandrel 7. Such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 and Figure 6 shown.

Embodiment 2

[0040] It is a combined buffer of polymer elastic elements and metal friction elements in a square shell. There is an isosceles trapezoidal protrusion on the side wall surface of the upper chamber of the shell 1 and the right-angled surface of the wedge block. The wedge block 5 and the upper chamber of the shell The right-angled surface in contact with the side wall is provided with an isosceles trapezoidal groove matching the isosceles trapezoidal protrusion at the position corresponding to the isosceles trapezoidal protrusion on the side wall of the upper chamber, and the isosceles trapezoidal protrusion and the isosceles trapezoidal concave The half-angle of the isosceles trapezoid of the groove is β, π / 2≥β≥0, the β of embodiment 2 is 30°, the wedge-shaped block mounting body 4 is a square body, and the square body 2 has 4 symmetrical wedge-shaped grooves on the outer surface, 4 Right-angled trapezoidal wedge block 5 is matched with the wedge-shaped groove of wedge-shaped bl...

Embodiment 3

[0042] It is basically the same as Embodiment 2, except that the wedge block 5 is divided into two symmetrical blocks from the symmetrical center line of the isosceles trapezoidal groove. Such as Figure 12 , Figure 13 and Figure 14 shown.

Abstract

A high polymer elastic component and metal friction component combined buffer with a polygonal housing comprises a housing, a group of high polymer elastic components, a group of metal spacers, a wedge-shaped block mounting body, a wedge-shaped block body, a press block, a mandrel, a nut and a thread connecting anti-loosening part, wherein the high polymer elastic components, the metal spacers, the wedge-shaped block mounting body, the wedge-shaped block body and the press block are fixedly connected with the housing through the nut and the thread connecting anti-loosening part, which are at the end part of the mandrel. The invention has the beneficial effects that the high polymer elastic component and metal friction component combined buffer has higher energy absorbing rate than the traditional elastomer buffer, and working environments of the elastic components and the metal spacers of the high polymer elastic component and metal friction component combined buffer are better than those of the traditional elastomer buffer; and the high polymer elastic component and metal friction component combined buffer also has the advantages of simple structure, low part number, low manufacturing cost, simple use and maintenance and high reliability.

Description

technical field [0001] The invention belongs to the technical field of mechanical engineering, in particular to mechanical equipment for reducing vibration and alleviating impact, in particular to a coupler buffer for locomotives and vehicles. Background technique [0002] Among the freight locomotive and vehicle coupler buffers currently used at home and abroad, the vapor-liquid and cement buffers have better buffering performance, but the reliability is average; the rubber buffer has a lower capacity; the all-steel friction buffer has high reliability, but the buffer The performance is unstable and discrete; the friction cement and friction hydraulic buffer have excellent cushioning performance, but these two types of buffers have complex structures and poor reliability. [0003] The polymer elastomer (TPEE) buffer has good anti-aging performance, and its sensitivity to temperature is much lower than that of rubber to temperature. It has strong vibration absorption ability...
