Abstract
The invention relates to a double-action buffer. The double-action buffer comprises a shell, a left end cover, a right pull ring, elastomer accommodating cavities, elastomers accommodated in the elastomer accommodating cavities, a central shaft and a middle clapboard, wherein the central shaft passes through the centers of the left end cover and the right pull ring and is in sliding contact with the left end cover and the right pull ring; one end of the central shaft extends out of the left end cover; the middle clapboard is fixedly arranged on the central shaft and divides the inner part of the shell into the two elastomer accommodating cavities to form a stretching side and a compressing side; and the elastomers are arranged in the two elastomer containing cavities. The buffer has the advantages of goof buffering effect, convenient installation, abrasion prevention and good overload protection effect due to an arranged overload protection device.
Description
Technical field
The present invention relates to a kind of passenger train shock absorber, particularly a kind of double-action type energy disperser that is applicable to the light rail hitch.
Background technology
Energy disperser (or bumper) is widely used in each neck city such as automobile, construction machinery and equipment, petroleum machinery, highway bridge, the energy disperser that uses or the kind of bumper are a lot, but mainly contain several big classes such as oil pressure damper, spring damper and rubber absorbers with regard to its working medium.And the energy disperser that is applied to the above-listed workshop of guideway vehicle mainly contains bumper, friction-type energy disperser, rubber draft gear, friction rubber type energy disperser, water bumper and air dashpot etc.Along with the development of railway cause, light rail has begun progressively to build, and the present invention is intended to develop a kind of two-way function energy disperser at Changchun light rail 70% low floor vehicle.
Summary of the invention
The double-acting buffer that the object of the present invention is to provide a kind of semi-permanent car coupler that is used between light rail unit, Changchun to use.
Technical scheme of the present invention is: a kind of double-action buffer, comprise housing, left end cap, right draw ring, elastic body containing cavity, be loaded on the elastic body in the elastic body containing cavity, center shaft and median septum, described center shaft passes the center of left end cap, right draw ring, and with the two moving contact, one end of center shaft stretches out left end cap, median septum is installed on the center shaft, and enclosure interior is divided into two elastic body containing cavities, form tensile side and compressed side, elastic body is positioned at two elastic body containing cavities.
Preferably: be provided with protruding backing plate and flat bolster between described elastic body and left end cap, the right draw ring, and adopt the circular conical surface fit system between protruding backing plate, flat bolster and left end cap, the right draw ring.
Preferably: described double-action buffer is provided with the stretching overload protection device, for the shaft shoulder that is provided with on the center shaft and be positioned at boss on the protruding backing plate.
Preferably: described double-action buffer is provided with the compression overload protection device, for being arranged at the boss on the left end cap and being positioned at the center shaft nut that center shaft stretches out left end cap one end.
Beneficial effect of the present invention is: energy disperser of the present invention is made up of tensile side and compressed side two parts, buffer element is an elastic body, by certain precompressed compression two groups of elastic bodys are assemblied in the housing composition, formed double-action buffer, two groups of energy dispersers are separated by median septum, median septum and center shaft are fixed together, formed the structure that drives median septum compression stretching side or compressed side energy disperser by seesawing of center shaft, good buffer effect, protruding backing plate and flat bolster and end cap or draw ring have adopted the circular conical surface fit system, not only easy for installation, and by the good fix between the conical surface, guarantee that its endoporus does not contact with center shaft, thereby avoided wearing and tearing; Be provided with overload protection device, when stretching overload, the ad hoc shaft shoulder of center shaft can contact with the boss of protruding backing plate, and power is directly passed to housing, and during the compression overload, the center shaft nut can contact with end cap, and power is directly passed to housing, and overload protection is effective.
Description of drawings
Fig. 1 is a sectional structure scheme drawing of the present invention
The specific embodiment
Below in conjunction with description of drawings the specific embodiment of the present invention:
A kind of double-action buffer, comprise housing 1, left end cap 2, right draw ring 3, elastic body containing cavity, be loaded on the elastic body 4 in the elastic body containing cavity, center shaft 6 and median septum 7, described center shaft 6 passes the center of left end cap 2, right draw ring 3, and with the two moving contact, one end of center shaft 6 stretches out left end cap 2, median septum 7 is installed on the center shaft 6, and housing 1 inside is divided into two elastic body containing cavities, form tensile side 5 and compressed side 8, elastic body 4 is positioned at two elastic body containing cavities.Be provided with protruding backing plate 9 and flat bolster 10 between described elastic body 4 and left end cap 2, the right draw ring 3, and adopt the circular conical surface fit system between protruding backing plate 9, flat bolster 10 and left end cap 2, the right draw ring 3.Described double-action buffer is provided with the stretching overload protection device, for the shaft shoulder 11 that is provided with on the center shaft 6 and be positioned at boss 12 on the protruding backing plate 9.Described double-action buffer is provided with the compression overload protection device, for being arranged at the boss 13 on the left end cap 2 and being positioned at the center shaft nut 14 that center shaft 6 stretches out left end cap 2 one ends.
Energy disperser is made up of tensile side 5 and compressed side 8 two parts, is assemblied in the housing composition by certain precompressed compression, has formed balanced structure, therefore, energy disperser single-piece initial pressure is equivalent to 0, and during use, energy disperser is in traction state and compressive state mostly, when being in traction state, center shaft 6 drives median septum 7, the elastic body 4 of median septum 7 compression stretching sides 5, and tensile side 5 elastic bodys 4 are compressed, compressed side 8 elastic bodys 4 are followed spreading, can in time remedy the deformation space that compressed side 8 is vacateed; During compression, compressed side 8 elastic bodys are compressed, and tensile side 5 elastic bodys are followed spreading, can in time remedy the deformation space that compressed side 8 is vacateed; Therefore, integral structure is a double-action buffer.When stretching overload, the center shaft 6 ad hoc shaft shoulders 11 can contact with the boss 12 of protruding backing plate 9, and power is directly passed to housing 1; During the compression overload, center shaft nut 14 can contact with the boss 13 on the left end cap 2, and power is directly passed to housing 1, and overload protection is effective.
