Abstract

The utility model relates to a split abrasion disc of a bogie core disc of a railway vehicle, which is designed particularly for solving the problems that the split abrasion disc has a short service life and has to be replaced frequently. The utility model also adopts the original basin-shaped structure which is synthesized by a disc ring and a disc base, but the disc ring and the disc base are in the structure of a split type. Due to the separation of the disc ring and the disc base, the phenomena of avulsion, crack at the root part of the disc, etc., by the uneven stress and the stress concentration between the disc ring and the disc base can be effectively avoided, which extends the service life of the split abrasion disc, reduces the maintenance load of the railway vehicle, and enables the direct maintenance cost of the components to reduce 50%. The utility model has remarkable effects on reducing the operating cost of the railway vehicle and enhancing the operation safety.

Description

The split type abrasion dish of bogies for railway vehicles cartridge

The utility model relates to the parts on a kind of bogies for railway vehicles, the split type abrasion dish of specifically a kind of bogies for railway vehicles cartridge.

Between the body center plate and truck center plate of bogies for railway vehicles, the abrasion dish all is installed, the wearing and tearing when its objective is between the upper and lower cartridge of bogie truck, buffering vehicle to run kinetic energy, the service life of prolongation bogie truck cartridge in order to the minimizing Vehicular turn.Existing abrasion dish is by coil and tries to get to the heart of a matter and be encircled into peviform, and the center of trying to get to the heart of a matter is porose to be enclosed within on the connection bearing pin of upper and lower cartridge, and coil is suitable for reading straight overhanging rim.The structure design of this abrasion dish is unreasonable, and promptly at Ackermann steer angle, the lateral pressure of the upper and lower cartridge of bogie truck strengthens, its result: the one, and the coil abrasion loss of abrasion dish is often greater than the abrasion loss of trying to get to the heart of a matter; The 2nd, the relative displacement of the upper and lower cartridge of bogie truck when turning, the very easy coil that causes the abrasion dish rhegma of tearing or try to get to the heart of a matter; The 3rd, coil rim suitable for reading is straight overhanging, with the coil unbalance stress time, easily causes stress concentration, causes rhegma.For above-mentioned reasons, make that the service life of abrasion dish is very short, change very frequently, and be unfavorable for protecting the upper and lower cartridge of bogie truck.

The purpose of this utility model just provides the split type abrasion dish of a kind of bogies for railway vehicles cartridge, to prolong the service life of abrasion dish, guarantees the safe reliability of rolling stock operation.

The utility model is achieved in that the abrasion dish still is by the coil and the synthetic peviform of trying to get to the heart of a matter, but coil is split-type structural with trying to get to the heart of a matter, it is cylindric to be that coil becomes, try to get to the heart of a matter and be the disk shape of band centre hole, coil is combined into an abrasion dish with trying to get to the heart of a matter, and places between the upper and lower cartridge of bogie truck by former mode.Because coil is separated with trying to get to the heart of a matter, therefore avoided effectively trying to get to the heart of a matter and coil between because of phenomenons such as tearing of occurring of unbalance stress, stress concentration and packing portion rhegmas, thereby prolonged service life of abrasion dishes, reduced the maintenance load of rolling stock.The coil of split and trying to get to the heart of a matter has constituted independent abrasion circle and abrasion sheet, and can therefore saved material, and the direct maintenance of accessory can reduce by 50% according to using and the abrasion situation is changed respectively.Use of the present utility model to reducing the rolling stock operation cost, improving operation security, has significant effect.

Below in conjunction with accompanying drawing the utility model is further described.

Structural representation when Fig. 1 is the utility model installation.

Fig. 2 is the structural representation of the another kind of implementation of the utility model.

As shown in Figure 1, this split type abrasion dish is to be tried to get to the heart of a matter by cylindric coil 1 and sheet 2 to combine.The body center plate 5 of bogie truck is captiveed joint by bearing pin 6 with truck center plate 4, and coil 1 is contained in all side elevations of upper and lower cartridge, 2 bottom surfaces that are contained in body center plate 5 of trying to get to the heart of a matter.Coil 1 and trying to get to the heart of a matter 2 is combined into and the essentially identical abrasion dish of original structure.Because coil 1 and trying to get to the heart of a matter 2 is separated, so avoided tearing phenomenon arbitrarily because of what unbalance stress or stress concentration occurred.2 diameter try to get to the heart of a matter among Fig. 1 less than the end mouth internal diameter of coil 1, make coil 1 be enclosed within to try to get to the heart of a matter 2 outer ring.Also can be designed to structure shown in Figure 2,2 the diameter of promptly trying to get to the heart of a matter equates with the end mouth external diameter of coil 1, makes 2 end openings that are supported on coil 1 of trying to get to the heart of a matter.In a word, the effect of these two kinds of forms is identical with effect.

For solving answering the heart to concentrate and tearing problem of coil overhanging edge suitable for reading, a kind of settling mode preferably is that the Cross section Design of coil 1 outer 3 suitable for reading becomes circular-arc (as shown in Figure 1, 2), can reduce stress concentration thus, has improved the bulk strength of coil.

The casting mold oil-containing nylon new material manufacturing that this split type abrasion dish can adopt nanotechnology to strengthen is with the toughness and the resistance to abrasion of further raising abrasion sheet and abrasion circle.
