Abstract
The utility model relates to a cylindrical tension and compression transformation integrated buffer, which comprises an outer shell body and an inner cylinder body. A tension rod is arranged at the opening section, and reed main bodies are arranged in the cavity body of the inner core body and below the tension rod. Energy absorption cushioning elements are arranged in the cavity body of the inner cylinder body and below the reed main body. The tail end of the reed main body is provided with a piston which extends into the energy absorption cushioning element. The tension rod and the inner core body are installed in a single direction linkage mode, and the energy absorption cushioning element and the inner core body are installed in a single direction linkage mode. Because the tension and compression transformation is integrated in the buffer in a seamless mode, a car is loaded without precompression, the journey and the capacity of the energy absorption cushioning element can be fully used, the tension and compression transformation nearly has no interval and the capacity is equal, a moving element is well lubricated, so that the abrasion is small, the impact force is small, and the comfortability is better when vehicles run.
Description
Technical field
The utility model relates to a kind of guideway vehicle shock attenuation device, the tubular shock absorber that especially a kind of passenger train and city railway vehicle are used.
Background technology
Shock absorber is that vehicle is the most basic, one of most important parts, plays the effect of longitudinal impulse and protection vehicle, driver and conductor and mobile unit between the buffering vehicle.
Worldwide, the used for rail vehicle shock absorber mainly is divided into two big classes: a class stretches and compresses shared same buffer element, and another kind of stretching is closed with compression and used different buffer elements.Buffer element can only work by compression usually.
The major advantage of last class shock absorber is to have made full use of buffer element, compact conformation, but need a kind of switching mechanism that stretching is become compression.And stretch and the shock absorber that compresses shared same buffer element has two kinds of structures: a kind of is that tension and compression switching mechanism utilizes the spacing realization on the car body, and another kind is that tension and compression switching mechanism is integrated in shock absorber inside.Before a kind ofly need realize stretching and the conversion of compression by the element on the car body and position limiting structure, need bigger precompressed compression after the entrucking, lost the part capacity of energy-absorbing buffering element, can't make full use of stroke, bigger gap is arranged when stretching and compressing and converting, and wearing and tearing are big, and impulsive force is big; A kind of shock absorber in back does not need precompressed compression, and the gap when stretching and compressing and converting is very little, and it is also less to wear and tear, and has made full use of the capacity of buffer element, but the structure of existing transfer device is comparatively loaded down with trivial details, and the operational failure rate is higher, and service life is also shorter.
Stretch to close and use the shock absorber of different buffer elements not need switching mechanism, but only utilized half performance of buffer element, generally only be used under the less demanding situation of energy disperser with compression.
Summary of the invention
The purpose of this utility model is the many deficiencies at existing shock absorber existence, provides a kind of tension and compression conversion of tubular construction to be integrated into energy disperser in-to-in novel buffer.
Technical solution of the present utility model is: a kind of tubular tension and compression Transform Sets moulding energy disperser, comprise body skin and inner barrel, described opening part is equipped with pull bar, the cavity of inner barrel is interior, the below of pull bar is equipped with the spring cylindrical shell, the cavity of inner barrel is interior, the below of spring cylindrical shell is provided with the energy-absorbing buffering element, and the end of spring cylindrical shell is equipped with piston, and piston extends in the energy-absorbing buffering element, pull bar and inner barrel single-way linkage are installed, and energy-absorbing buffering element and inner barrel single-way linkage are installed.
Preferably, described spring cylindrical shell only within it portion be provided with elastic element.
Preferably, described inner barrel is a gyro-rotor, and has the spacing square hole that matches with the spring cylindrical shell on the wall within it, also is provided with the boss that prevents that the spring cylindrical shell from outwards moving on the body skin.
Preferably, the inwall of described inner barrel opening part is provided with Ka Tai, and the end of pull bar is provided with the convex edge of matching with Ka Tai, and the single-way linkage that forms inner barrel and pull bar is installed.
The beneficial effects of the utility model are: owing to will stretch and the seamless energy disperser inside that is integrated into of compressing and converting, therefore there is not precompressed compression after the entrucking, make full use of the stroke and the capacity of energy-absorbing buffering element, stretch and during compressing and converting very close to each other basically and etc. capacity, movement parts has good lubricating, it is little to wear and tear, and impulsive force is little, and the vehicle operating comfort level is better.And, owing to only be provided with elastic element, and spring is not set, so structure product more in the past compares greatly and simplifies in its outside in the inside of spring cylindrical shell, fault rate decreases, and also rise appreciably service life.In addition, the utility model both can be used in the shock absorber of the middle atresia of energy-absorbing buffering element, also can be used in the middle porose shock absorber of energy-absorbing buffering element, and Applicable scope is also more extensive.

The specific embodiment
A kind of tubular tension and compression Transform Sets moulding energy disperser, comprise body skin 1 and inner barrel 2, described opening part is equipped with pull bar 5, the cavity of inner barrel 2 is interior, the below of pull bar 5 is equipped with spring cylindrical shell 4, the cavity of inner barrel 2 is interior, the below of spring cylindrical shell 4 is provided with the energy-absorbing buffering element, and the end of spring cylindrical shell 4 is equipped with piston, and piston extends in the energy-absorbing buffering element 3, pull bar 5 is installed with inner barrel 2 single-way linkages, and energy-absorbing buffering element 3 is installed with inner barrel 2 single-way linkages.Described spring cylindrical shell 4 only within it portion be provided with elastic element.Described inner barrel 2 is a gyro-rotor, and has the spacing square hole that matches with spring cylindrical shell 4 on the wall within it, also is provided with the boss that prevents that spring cylindrical shell 4 from outwards moving on the body skin 1.The inwall of described inner barrel 2 opening parts is provided with Ka Tai, and the end of pull bar 5 is provided with the convex edge of matching with Ka Tai, forms inner barrel 2 and installs with the single-way linkage of pull bar 5.
When shock absorber was stretched loading, tensile force was delivered to inner core 2 by pull bar 5, was delivered to buffer element 3 then, was delivered to spring cylindrical shell 4 again, the hitch end that is delivered to housing 1 at last and links with housing 1.
During shock absorber loading by compression, compressive force is delivered to spring cylindrical shell 4 by pull bar 5, is delivered to buffer element 3 then, is delivered to inner core 2 again, is delivered to the hitch end that links with housing 1 at last.
