Abstract
The utility model relates to an elastomer type compact buffer comprising a shell, an end cover positioned at one end of the shell, a pull rod inserted in the shell from the end cover, an elastomer spring sheathed on the pull rod, and a limiting device. The pull rod comprises an inner pull rod and an outer pull rod, wherein the outer pull rod is sheathed at one end of the inner pull rod, the elastomer spring is sheathed on the inner pull rod, a base and a front baffle plate are sheathed at two ends of the elastomer spring on the inner pull rod, the front baffle plate props against the end cover and the outer pull rod, and limiting nuts are arranged at the outer parts of one ends of the outer pull rod and the inner pull rod. The elastomer type compact buffer is simple and compact in structure, reasonable in design, convenient for installation and uniform in stress, occupies small space without affecting the self performances, can provide more installation spaces for other components, and has low manufacturing and maintaining cost.
Description
Technical field
The utility model relates to a kind of guideway vehicle shock attenuation device, particularly a kind of city rail tight lock coupler elastomeric-type energy disperser that is applicable to.
Background technology
Energy disperser plays an important role in vehicle operating, when transmitting the train travelling process longitudinal force, play the effect that relaxes longitudinal impulse, thereby, people never stop for the development of energy disperser, the combined buffers of concurrent exhibition steel spring formula energy disperser, water bumper, rubber draft gear and above type buffer etc., development along with the railway cause, the increase of the various functions of train, installing space is also more and more valuable, thereby, how solving this type of problem becomes key, and the energy disperser of developing a kind of close-coupled is significant.
The utility model content
The purpose of this utility model is the shortcoming at prior art, and a kind of reasonable in design is provided, elastomeric-type close-coupled energy disperser.
The technical solution of the utility model is: a kind of elastomeric-type close-coupled energy disperser, comprise housing, be positioned at the end cap of housing one end, from end cap be plugged in enclosure interior pull bar, be set in elastomeric spring and inhibiting device on the pull bar, described pull bar comprises draw-in bar and outside link, and outside link is set in an end of draw-in bar; Described elastomeric spring is set on the draw-in bar, and the two ends of elastomeric spring are set with base and cowl board on the draw-in bar, and cowl board props up end cap and outside link, and the outer setting of described outside link and draw-in bar one end has stop nut.
Preferably: between described outside link and the draw-in bar for being threaded.
Preferably: be provided with anti-rotating pin between described base and the housing, described anti-rotating pin is installed on the base, has the anti-rotating pin open slot on the housing.
Preferably: be provided with intermediate hsg between the described elastomeric spring.
The beneficial effects of the utility model are: the utility model is simple in structure reasonable in design, and compact conformation is convenient to install, stressed even, take up room little and do not influence itself performance, more space can be provided for the installation of miscellaneous part, make and the repair and maintenance cost low.
