でみろ。In the figure, reference numeral 1 denotes a frame frame constituting a truck, to which is attached an outer cylinder 3 whose inner surface is shaped like a cone, that is, a bell shape. Reference numeral 2 denotes an axle box body attached to both ends of the wheel axle, and a mandrel 5 having an outer peripheral surface formed in a conical shape, that is, a bell shape that can be fitted into the outer cylinder 3, is attached. The mandrels 5 are provided on both sides of the axle box body 2 in the longitudinal direction of the vehicle body, and the outer cylinder 3 is arranged so that its axial center coincides with the mandrel 5 of the bogie frame l. 4 is a ring-shaped roll rubber disposed between the inner circumferential surface of the outer cylinder 3 and the outer circumferential surface of the mandrel 5. That is, the roll rubber 4 is attached to the axle box body 2 via the core metal 5,

第５図により詳述すると、１Ｌず、該分解作業の方法と
しては。The above-mentioned prior art does not have a structure that takes into account the workability when disassembling one bogie, that is, removing the wheel axle from the bogie frame. For example, when grinding the tread surface of a wheel, one operation is performed after disassembling the axle spring device formed between the axle box body and the bogie frame. Figure 4 shows this disassembly work.
To explain in detail with reference to FIG. 5, the method for disassembling the work is as follows.

場合には、該ロールゴムが外筒３から離脱する恐ｎがあ
りた。As shown in Fig. 4, there is a method for removing the mandrel 5 at the press-fitted part into the roll rubber 4, a method for removing it at the part where the mandrel 5 is attached to the axle box body 2 as shown in Fig. Although there is a method for removing at the attachment point to the frame, the method for removing at the attachment point between the outer cylinder 3 and the bogie frame is not normally applied from the point of view of workability, and will therefore be omitted from the following explanation. However, in the method shown in FIG. 4, the inner circumferential surface of the outer cylinder 3 is formed into a conical shape, and the roll rubber 4 is press-fitted into the inner circumferential surface of the inner cylinder 3, so that the pressing force by the mandrel 5 is reduced. If it runs out, the roll rubber 4 moves toward the larger diameter side of the outer tube 3, that is, outward, due to its restoring force, and protrudes from the m section of the outer tube 3, as shown by the dotted line in FIG. In the worst case, there was a risk that the roll rubber would separate from the outer cylinder 3.

At the same time, there was a risk that the mandrel 5 would be pushed out by the restoring force of the roll rubber 4 and fall from the state where it was fitted to the roll rubber 4.
したがって、前述のようなロールゴム４の外筒３からの
はみ出しによって、再組立時に該ロールゴムの位置がず

性が変化する恐れがあった。Therefore, due to the protrusion of the roll rubber 4 from the outer cylinder 3 as described above, there is a risk that the position of the roll rubber will shift during reassembly, changing the support height of the shaft spring device or changing the elasticity characteristics. Ta.
特に、軸ばね装置全体の支持高さが変化すると。Especially when the support height of the entire axial spring device changes.
所期のロールゴム特性が得られず１乗心地および走行安
定性の低下を招く恐れがあった。There was a risk that the desired roll rubber properties could not be obtained, leading to a decrease in riding comfort and running stability.

Since this can be prevented, reassembly work can be carried out easily. Further, since the fitted state of the roll rubber and the mandrel can be maintained during one disassembly due to the fitting holding portion provided at the tip of the mandrel, the work at the time of reassembly can be carried out easily.
以下１本発明による一実施例お４び他の実施例を第１図
および第２図により説明する。Hereinafter, one embodiment, fourth embodiment, and other embodiments of the present invention will be explained with reference to FIGS. 1 and 2.

られている。In FIG. 1, reference numeral 8 denotes an outer cylinder which is attached to the bogie frame like the outer cylinder of the conventional example, and whose inner circumferential surface is formed into a conical shape, that is, approximately 1-shape. Further, a protrusion 9 corresponding to a roll rubber holding portion that protrudes inward, that is, toward the axial center of the outer cylinder 3, is provided at a large diameter portion of the inner circumferential surface, that is, a portion close to the edge of the outer cylinder 3.

９は全周に形成されているが、断続的に設置してもなん
ら問題はない。The size of the protrusion 9 is such that when the roll rubber 4 is press-fitted into the outer cylinder 3 and is not subjected to any other force, the roll rubber can overcome the outward movement force generated by the restoring force of the roll rubber 4 itself. 4. Set the force to hold 4. on the other hand,
The projection s9 also needs to have a size that allows the roll rubber 4 to be easily press-fitted into the outer cylinder 8. Incidentally, in the figure, the projections 9 are formed all around the circumference, but there is no problem if they are installed intermittently.

。Next, numeral 10 denotes a mandrel which is attached to the axle box like the mandrel of the conventional example, and whose outer peripheral surface is formed into a conical shape, that is, a bell shape. Further, at the tip of the core mass 10, a protrusion U corresponding to a fitting holding portion protruding in the radial direction is provided. This protrusion 11 is formed to a size that maintains the fitted state of the mandrel 10 to the roll rubber 4 against the force of pushing out the mandrel 10 due to the restoring force of the roll rubber 4. On the other hand, the protrusion n needs to have a size that allows the mandrel 10 to be easily inserted into the roll rubber 4.
二のような構成において、軸ばね装置を台車、枠と輪軸

。In the second configuration, a case will be described in which the shaft spring device is disassembled along with the separation of the truck, frame, and wheel axle. first,
When separating the roll rubber 4 and the mandrel 10,
Since the roll rubber 4 is prevented from moving outward of the core outer cylinder 8 and is held by the protrusion 9 of the outer cylinder 8, the roll rubber 4 does not protrude outward from the outer cylinder 8. By the way, when separating the roll rubber 4 and the mandrel 10 as described above, it is advantageous not to provide the protrusion 11 of the mandrel 10.
一方、心金１０と軸箱体との間で分離をする場合には、

調整等が不要となり１作業性の向上が図れろ。According to the configuration 2, it is possible to prevent the roll rubber 4 from protruding from the outer cylinder 8 when the shaft spring device described in llr is disassembled, so that the height of the shaft spring device changes after reassembly and the characteristics change. It is possible to prevent deterioration of riding comfort and running stability due to Also, when reassembling the roll rubber 4, the outer cylinder 8
Since it is located at a predetermined position relative to the rubber roll 4, it becomes unnecessary to adjust the position of the roll rubber 4, thereby improving work efficiency.

Since the roll rubber 4 is held in the outer cylinder 8 and the mandrel 10 does not come off from the roll rubber 4, reassembly work can be easily performed and the outer cylinder 8. Since the respective positional relationships between the roll rubber 4 and the mandrel 10 are maintained in a predetermined state, changes in characteristics after reassembly can be prevented.

When the roll rubber 4 is separated between the roll rubber 4 and the mandrel 5, the force of the roll rubber 4 moving outward from the outer cylinder 12 due to the restoring force of the roll rubber 4 itself can be suppressed by the cylindrical part 13. It can prevent protrusion from the tube edge.
一方、心金１４と軸箱体との間で分離する場合。On the other hand, when the mandrel 14 and the axle box body are separated.
