Abstract
The utility model relates to a rail vehicle elasticity clay buffer core, including core shell, core protecgulum, clay, piston, piston rod, characterized by: be equipped with the guide ring in the core shell, it is fixed with core shell inner wall that interference fit is passed through to the guide ring outer fringe, and it has 6-8 through -holes to open on the guide ring, be fixed with the guide ring copper sheathing through interference fit in the centre bore of guide ring, the piston setting is on the piston rod, and the both ends of piston rod are located the both sides of piston respectively, form the cross with the piston, and the anterior segment of piston rod passes the core protecgulum, and the back end of piston rod is worn at the guide ring copper sheathing to with guide ring copper sheathing clearance fit. Its advantage is: compact structure, reasonable is convenient for make. Lead through guide ring and copper sheathing support piston rod, at the piston motion in -process, improved the stationarity of motion process greatly, avoided piston and core shell inner wall to take place the problem of interfering, showing and improving fatigue life.
Description
Technical field
The utility model relates to a kind of railway vehicle elastic cement buffer core body, belongs to railway vehicle coupler damping device technical field.
Background technique
Buffer is the vitals of rail vehicles, and the energy-absorbing mode according to buffer can be divided into following a few class usually: friction buffer (containing dry friction type, lubricated type buffer), rubber bumper (containing elastomeric bumpers), elastic cement buffer, hydraulic bjuffer (containing hydro-pneumatic buffer), combined type (combination of several energy-absorbing mode) buffer etc.
Wherein: elastic cement buffer is compared with common buffer, have that structure is simple, striking velocity is high, capacity is large, resistance is stable, plurality of advantages, the function admirable such as stable performance, high-durability reliability, quality are light.Owing to having the incomparable high technology performance of other conventional buffer, elastic cement buffer is a kind of desirable buffer, so obtain popularization rapidly, and remains good growth momentum.
At present, usual railway vehicle elastic cement core body piston rod moves vertically in cylinder body, and easily form larger biasing force, time serious, piston can abrade cylinder inboard wall, and buffer fatigue behaviour is poor.
Summary of the invention
The purpose of this utility model is to provide and a kind ofly can realizes the location of piston rod and the effect of guiding, can prevent again piston rod from bearing excessive unbalance loading loading force, fatigue behaviour is had a distinct increment, ensures the reliability of elastic cement buffer and the Security reliable railway vehicle elastic cement buffer core body of train operation of railway vehicle.
The purpose of this utility model realizes with the following methods:
The railway vehicle elastic cement buffer core body that the utility model provides, comprise core body shell, core body protecgulum, clay, piston, piston rod, it is characterized in that: in core body shell, be provided with guide ring, guide ring outer rim is fixed by interference fit and core body outer casing inner wall, and guide ring has 6 ~ 8 through holes; Guide ring copper sheathing is fixed with by interference fit in the center hole of guide ring, piston is arranged on the piston rod, the two ends of piston rod lay respectively at the both sides of piston, criss-crossing is formed with piston, the leading portion of piston rod is through core body protecgulum, the back segment of piston rod is through guide ring copper sheathing, and with guide ring copper sheathing Spielpassung.
The utility model has the advantages that: compact structure, rationally, be convenient to manufacture.Led by guide ring and copper sheathing support piston bar thereof, in piston movement process, substantially increase the stationarity of movement process, effectively prevent the problem that piston and core body outer casing inner wall interfere, significantly improve fatigue life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of guide ring;
Fig. 3 is the stereogram of guide ring;
Fig. 4 is the structural representation of piston and piston rod.
Embodiment
With reference to accompanying drawing, the utility model comprises core body shell 5, core body protecgulum 1, clay 4, piston 6, piston rod 7, core body enclosure is full of elastic cement 4, guide ring 3 is provided with in core body shell, guide ring outer rim is fixed by interference fit and core body outer casing inner wall, guide ring has 6 ~ 8 through holes 8, makes clay by guide ring free-flow in core body enclosure cavity; In the center hole of guide ring, be fixed with guide ring copper sheathing 2 by interference fit, piston is arranged on the piston rod, and the two ends of piston rod lay respectively at the both sides of piston, form criss-crossing with piston, and piston and piston rod can make integrative-structure.The leading portion of piston rod is through core body protecgulum, and the back segment of piston rod is through guide ring copper sheathing, and with guide ring copper sheathing Spielpassung, piston rod can be slided relative to guide ring copper sheathing.Led by guide ring 3 and copper sheathing 2 support piston bar 7 thereof, therefore in piston movement process, substantially increase the stationarity of movement process, effectively prevent the problem that piston and core body outer casing inner wall interfere, significantly improve its fatigue life.
