Abstract
The invention relates to a center plate for lorry, belonging to the field of rail transporting vehicles. The invention comprises a center plate and a center plate base. The center plate is located on the center plate base. The key technology is that the center plate base comprises a soleplate and a web casted integrally. The web is a wing-shaped structure having a lower limb longer than the upper limb. The center plate has reasonable structure and strong bearing ability.
Description
(1) technical field:
A kind of center plate for lorry belongs to the railway transport vehicle field, particularly relates to the cartridge that railway truck is used.
(2) background technology:
Center plate for lorry is mainly used in the application force that transmits between car body and the bogie truck, is one of critical component of rolling stock.The cartridge on the whole of present most lorries is because of structure problem, and transfer function power causes stress concentration well, and the phenomenon that ubiquity stress is bigger than normal makes cartridge crack easily, influences the cartridge bearing capacity.
(3) summary of the invention:
The problem to be solved in the present invention provides a kind of rational in infrastructure at above deficiency exactly, and load-carrying capacity is strong, reduces the cartridge of maintenance number of times.Its technical scheme is as follows:
It comprises cartridge and center filler, and cartridge is positioned on the center filler.Its gordian technique is that center filler comprises base plate and web, is provided with web in the both sides of base plate, and base plate and web integral casting forming, web are the wing-shaped structure of the following length of side greater than the top length of side.
Compared with prior art the beneficial effect that has of the present invention is:
1, the web of center filler adopts the short wing-shaped structure in length of side top down, has better carrying application force, and the cartridge load-carrying capacity is strengthened.
2, because the web of center filler adopts the wing-shaped structure of the following length of side greater than the top length of side, web and base plate casting constitute low wide and up narrow formula shaped as frame center filler, and be rational in infrastructure, transfer function power better, avoid stress concentration, cartridge is not easy to crack, and has reduced the maintenance number of times.
(4) description of drawings:
Fig. 1 is a structural representation of the present invention;
Fig. 2 is Fig. 1 birds-eye view;
Fig. 3 is a web structure scheme drawing of the present invention.
(5) specific embodiment:
Embodiment one:
Referring to accompanying drawing, the present invention includes cartridge 1 and center filler 2, cartridge 1 is positioned on the center filler 2.Its gordian technique is that center filler 2 comprises base plate 4 and web 3, is provided with web 3 in the both sides of base plate 4 perpendicular to base plate, and base plate and web integral casting forming constitute the shaped as frame center filler, and web 3 is following length of side wing-shaped structures greater than the top length of side.
Embodiment two:
Referring to accompanying drawing, the present invention includes cartridge 1 and center filler 2, cartridge 1 is positioned on the center filler 2.Its gordian technique is that center filler 2 comprises base plate 4 and web 3, both sides at base plate 4 are provided with web 3 perpendicular to base plate, base plate and web integral casting forming, constitute the shaped as frame center filler, what be positioned at cartridge 1 in center filler 2 is provided with gusset 5 all around, and web 3 is following length of side wing-shaped structures greater than the top length of side.
This cartridge adopts the casting of B+ level steel, and intensity is higher.
Claims (2)
