Abstract
The invention discloses a buffering device of a ring spring and elastic daub combined structure. The ring spring and elastic daub combined structure is adopted, a flexible spring box cover is arranged at the left end of a spring box, a spring box bottom board is arranged at the right end of the spring box, a piston cylinder is arranged in the center inside the spring box, an elastic daub core body is arranged in the piston cylinder, the piston rod end abuts against the inner wall of the spring box cover, an inner ring spring is arranged outside the piston cylinder, a left-end outer ring spring is arranged at the left end of the external portion of the inner ring spring, and a right-end outer ring spring is arranged at the right end of the external portion of the inner ring spring. On one hand, the impaction energy acted on the ring springs is absorbed through deformation and mutual friction of the ring springs during the compressing and recovering process, and on the other hand, impact force is transferred to the elastic daub core body, a piston of the elastic daub core body compresses the elastic daub core body, and the damping generated by flowing of the daub is used for absorbing the impaction energy.
Description
Technical field
The invention belongs to the shock absorber between the locomotive, Passenger Vehicle, truck vehicle of railroad train, particularly the energy disperser of annual spring and elastic cement composite structure.
Technical background
Energy disperser is used for, between vehicle, playing buffering energy-absorbing function.Be used for transmitting and absorption Lognitudinal Impact of Trains energy, reduce longitudinal impact, the protection vehicle structure, improve Comfortability of Train and quiet degree, belongs to hitch buffering energy-consumption device.
Along with the Ministry of Railways, to the general requirement that railway transportation proposes fast, heavy duty develops, no matter be the speed of a motor vehicle, the load-carrying of load carrying vehicle, the gross load hauled of passenger vehicle, the lorry running velocity all improves constantly.This development form requires more and more higher to the buffer capacity of energy disperser.This type energy disperser meets the requirement of heavy haul transport more than can realizing that buffer capacity reaches 80KJ.
Summary of the invention
The invention provides a kind of a kind of energy disperser of used for rail vehicle, this type energy disperser meets the requirement of heavy haul transport more than can realizing that buffer capacity reaches 80KJ.
Content of the present invention:
The energy disperser of a kind of cup spring and elastic cement composite structure, it is characterized in that: adopt annual spring and the compound structure of elastic cement, at the spring case left end, movable end cap is arranged, at the spring case right-hand member, the spring case base plate is arranged, at spring case Nei De center, it is piston barrel, the in-built flexible clay core body of piston barrel, rod end withstands on the end cap inwall, inner ring is housed outside piston barrel, left end in the inner ring outside is equipped with the left end outer ring spring, and the right-hand member in the inner ring outside is equipped with the right-hand member outer ring spring.
Characteristic advantage of the present invention:
Act on the impact energy of energy disperser, by cup spring, distortion and the phase mutual friction in compression and recuperation is absorbed on the one hand, impulsive force is passed to the elastic cement core body on the other hand, and the piston compression elastic cement of elastic cement core body utilizes the mobile damping produced of clay to carry out apparatus with shock absorbing.Keystone configuration adopts annual spring and the compound structure of elastic cement, and the main technical details of energy disperser is as follows:
Resistance 2450KN
Stroke 73MM
Capacity 80KJ
Absorptivity 75%
The accompanying drawing explanation
Fig. 1 is the energy disperser cutaway view of cup spring and elastic cement composite structure.
In figure: 1 spring case, 2 end cap, 3 base plates, 4 elastic cement core bodys, 5 inner rings, 6 left end outer ring springs, 7 right-hand member outer ring springs, 8 piston barrels, 9 piston rods.
The specific embodiment
A kind of cup spring as shown in the figure and the energy disperser of elastic cement composite structure, adopt annual spring and the compound structure of elastic cement, at the spring case left end, movable end cap is arranged, at the spring case right-hand member, the spring case base plate is arranged, at spring case Nei De center, it is piston barrel, the in-built flexible clay core body of piston barrel, rod end withstands on the end cap inwall, inner ring is housed outside piston barrel, left end in the inner ring outside is equipped with the left end outer ring spring, and the right-hand member in the inner ring outside is equipped with the right-hand member outer ring spring.
The elastic cement core body is placed in the inside of annual spring, and the outside of annual spring is covered with spring case, the damping characteristics of this energy disperser:
Resistance 2450KN
Stroke 73MM
Capacity 75KJ
Absorptivity 75%
Connected by bolt between the spring case of this energy disperser, adopt black nut, prevent the loosening of nut and come off.
