Abstract
The utility model relates to an elastic bind buffer with split flow energy storage function. The utility model belongs to a buffer device technology field. The current spring and friction spring multi-mechanical form buffers applied on the vehicle hook no longer satisfy the demand of high speed train due to the small volume and heavy abrasion on performance. The utility model is characterized in that the peripheral shed side of a circular buffer shell full of elastic binds is provided with two opposite semicircular accumulators, while an energy leaking hole is arranged near the end part to communicate with the shell cavity. The utility model greatly improves buffing capability and service performance; and in addition, the old buffer can be replaced with the original vehicle hook.
Description
Technical field: the utility model relates to a kind of shock absorber, exactly, is a kind ofly to bear vehicle towed company and hang energy disperser in the coupler device of function, is a kind of elastic cement buffer.
Background technology: along with vehicle load, Gross Train Weight and running velocity increase, and the marshalling yard vehicle allows the raising of coupling speed, the former this mechanical type energy disperser such as spring one friction-type energy disperser, rubber draft gear that is used on the hitch is little because of its buffer capacity, mechanical wear is serious, also produce permanent deformation, shortcomings such as performance shakiness can not adapt to the more large impact power of high speed train and shunting impact's speed of Geng Gao.In recent years, in order to adapt to the operation needs of high speed train, passenger vehicle, lorry, elastic cement buffer occurs, it is big that it has buffer capacity, and resistance is little, simple in structure, stable performance, little, the lightweight advantage of volume.
Summary of the invention: the utility model is to improve by inner structure to seek the further raising of elastic cement buffer buffer capacity, exactly do not change former hitch by the assembling structure condition under, improve buffer capacity.
The utility model is realized in the following manner: the opening part that evenly is full of the cylindric energy disperser housing of elastic cement, the seal cover cap sealing of being located the piston rod that can move freely by centre hole is fastening, can hinder in cavity that the mud shape moves, the piston of band cutoff port is fastened on the piston rod, the housing peripheral skirt, two semicircular cylinder energy storages of symmetry are arranged, and close end is let out and can be communicated with the shell chamber in the hole.
As medium, it has elasticity to this energy disperser with elastic cement, compressibility and flowing power, and its physical and chemical performance has advantages of higher stability in-50～+ 250 ℃ of scopes, antiageing, odorless, nontoxic, environmentally safe.It has the feature of solid and two kinds of attributes of liquid, its kinetic viscosity than normal hydraulic oil big tens to hundred times.Compare with general friction-type energy disperser, its capacity is much bigger, and resistance is little.
Description of drawings: Fig. 1 is the utility model structural principle cutaway view
Fig. 2 is the structural principle lateral plan
The specific embodiment: the opening part that evenly is full of the cylindric energy disperser housing 2 of elastic cement 1, seal cover cap 3 sealings of being located the piston rod that can move freely by centre hole are fastening, can hinder in cavity that the mud shape moves, the piston 4 of band cutoff port is fastened on the piston rod 5.The housing peripheral skirt has two semicircular cylinder energy storages 6 of symmetry, and close end is let out and can be communicated with the shell chamber in hole 7.
In being full of the buffering body of elastic cement material, the piston of band cutoff port, when piston rod is subjected to impulsive force, the elastic cement material produces resistance by compression, the compressive deformation of clay material absorbs impact energy, and by cutoff port with let out can the hole stored energy, because clay properties of materials and increase this version of energy storage, impulsive force is big more, and the capacity of energy disperser also increases thereupon.After the pressure on the piston rod was removed, the elastic cement cubic expansion can reflux in the hole with letting out by cutoff port, makes piston get back to original position.
