Abstract
An underframe end energy absorbing structure is characterized by comprising an energy absorbing frame, an energy absorbing box and an energy absorbing material. The energy absorbing box is fixed on the energy absorbing frame and consists of a box body, an anti-collision post, an anti-creeping plate, a guide rail and a positioning pin, the anti-collision post is connected with the box body through bolts, and the anti-creeping plate and the guide rail are integrated with the box body through welding. The energy absorbing box and the energy absorbing material are sequentially loaded into a car with slide slots, the energy absorbing material is arranged between the car and the energy absorbing box, and the energy absorbing box is fixed with the car by the positioning pin after assembly. The positioning pin for fixing the energy absorbing box can be cut off by shear force when two cars are in collision, load is applied to the energy absorbing material by the energy absorbing box along the slide slots in the car through the guide rail, energy is released when an energy absorbing block is crushed under action of the load, and accordingly the purpose of protecting the car and passengers is realized.
Description
Technical field
The utility model relates to car body underframe end endergonic structure.
Background technology
Railroad car bodywork intensity existing domestic, international operation is accepted by industry as an extremely important index weighing vehicle performance, UIC566, EN12663, TB1335 etc. are widely used as the standard that guarantees car body strength, under the prerequisite of assurance function, how car body is done the stronger designer's of being striving direction.But the designer often ignores a problem, when hanging over, the so strong vehicle connection of many structures forms a marshalling, the end of up-to-date contact is because without any endergonic structure and device when bumping, and powerful collision energy can only be along car body to the guest room transmission, thereby causes a large amount of personal casualty.
Existing vehicle mainly is hydraulic pressure, rubber, the elastic cement buffer that carries by the hitch itself that connection is hung, and realizes that the ability of the generation of vehicle in operational process absorbs and discharges, and guarantees comfortable, the smooth running of vehicle.And can only be by increase absorption and the release that side buffer solves energy in the underframe end for the vehicle that uses screw coupling.Energy-absorbing curve by hitch and energy disperser; apparent energy absorbing and discharging only can guarantee the less buffering that causes in the vehicle operating process; and in case the huge energy release that produces that bumps will directly cause hitch to damage; and then the car body that causes joining extension directly bumps, and do not play the purpose of passenger's personal safety in protection car body and the car.
The utility model content
Technical problem to be solved in the utility model can absorb the energy absorption device of collision energy when providing a kind of collision happens.
For solving the problems of the technologies described above, the utility model provides a kind of underframe end endergonic structure, it is characterized in that: comprise energy-absorbing framework, energy-absorbing case and energy-absorbing material, the energy-absorbing case is fixed on the energy-absorbing framework, the energy-absorbing case is made up of casing, collision post, anti-creep plate, guide rail, locating dowel pin, the collision post is connected with casing by bolt, and anti-creep plate and guide rail form one by welding and casing.
In the utility model when assembling, pack energy-absorbing case and energy-absorbing material in order into and have in the car body of chute, be energy-absorbing material between car body and the energy-absorbing case, fixes by locating dowel pin and car body at the assembling energy-absorbing case that finishes afterwards.Fixedly the locating dowel pin of energy-absorbing case is sheared power and cuts off when two collision happens; the energy-absorbing case imposes on energy-absorbing material along the car body internal chute with load by guide rail, and in the process with the energy absorbent block conquassation under loading, energy obtains discharging; thereby, play protection car body and passenger's purpose.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the birds-eye view of Fig. 1;
Fig. 3 is the cutaway view along A-A line among Fig. 1.
The specific embodiment
With reference to Fig. 1, Fig. 2, Fig. 3, the utility model comprises energy-absorbing framework 1, energy-absorbing case and aluminium honeycomb energy absorbent block 8, the energy-absorbing case is fixed on the energy-absorbing framework, the energy-absorbing case is made up of casing 4, collision post 7, anti-creep plate 3, guide rail 5, locating dowel pin 6, the collision post is connected with casing by bolt 9, and anti-creep plate and guide rail form one by welding and casing.
During assembling, energy-absorbing case and aluminium honeycomb energy absorbent block being packed in the car body 2 that has chute in order, is aluminium honeycomb energy absorbent block between car body and the energy-absorbing case, fixes by locating dowel pin and car body at the assembling back energy-absorbing case that finishes.When collision happens, two vehicle end anti-creep plates pass through the mutual interlock of groove of convex-concave, thereby prevent vehicle arch camber and stack, and the direction of transfer of load can only vertically be transmitted along car body.Being used for fixing energy-absorbing case composition locating dowel pin when bumping on the energy-absorbing framework of underframe end is cut off by great shear forces; energy-absorbing case composition imposes on aluminium honeycomb energy absorbent block along the chute in the car body with load by guide rail; in the process of load with the energy absorbent block conquassation; energy obtains discharging; thereby protect the integraty of car body, avoid passenger's damage to person.
