Furthermore, the terms "first", "second", etc. are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first," "second," etc. may explicitly or implicitly include one or more of that feature. In the description of the invention, the meaning of "a plurality" is two or more unless otherwise specified.

In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," "fixedly connected," and "fixedly connected" are to be interpreted broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the creation of the present invention can be understood by those of ordinary skill in the art through specific situations.

As shown in fig. 1 and 2, a compact type bogie wheel includes an outer end cover 1, an inner end cover 2, and a hub 3. The outer periphery of the hub is coated with a rubber layer 4, and the rubber layer can be directly vulcanized on the hub or fixed on the hub in other modes. The hub is hinged on the connecting shaft through a bearing 5, and in order to prevent the bearing from being separated from the connecting shaft, an elastic retainer ring 6 used for limiting the axial movement of the bearing is installed at the end part of the connecting shaft. The inner end cap and the outer end cap are fixedly connected to the inner side and the outer side of the hub through bolts 7 respectively, and in order to make the structure of the device more compact, as shown in fig. 3 and 4, two sides of the hub are shrunk inwards to form an end cap mounting area 8, and the inner end cap and the outer end cap are buckled with the area respectively. The middle part of the inner end cover is provided with a through hole 9, and the connecting shaft penetrates through the through hole to be connected with the hub. In order to prevent that impurity from entering into the bearing between interior end cap and the connecting axle sealed through sealing washer 10 between interior end cap and the connecting axle, specifically do, the middle part of interior end cap is to the sunken sealing washer storage tank 11 that forms of one side, arranges the sealing washer in this sealing washer storage tank, the utility model discloses in, the sealing washer adopts V-arrangement circle sealing member.

In order to form sealing between the inner end cover, the outer end cover and the hub, the inner end cover, the outer end cover and the hub are respectively sealed through O-shaped sealing rings 12, and specifically, the O-shaped sealing rings are installed in grooves 13 on the outer peripheral sides of the inner end cover and the outer end cover.

The loading wheel mounting mode is as follows: the O-shaped sealing ring 12 is arranged on the inner end cover and the outer end cover; fixing the inner end cover and the hub through bolts, and then installing the bearing into the hub to form a hub assembly; then, a sealing ring is arranged on the connecting shaft, and the sealing ring is limited by an annular bulge 14 on the connecting shaft; sleeving the hub assembly on a connecting shaft; then, a circlip 6 is used to fix the end of the connecting shaft to clamp the bearing, and finally, the outer end cover with the O-shaped sealing ring is fastened on the hub by bolts. The bogie wheels and the connecting shaft are mounted as shown on the right side of fig. 4.

The bogie wheels may be mounted in pairs at both ends of the connecting shaft 15 as shown in fig. 3. The mounting mode of a pair of loading wheels is as follows: firstly, the bogie wheel is arranged at one end of the connecting shaft with the annular bulge, then the connecting shaft passes through the through hole of the bogie wheel suspension 16 to be fixedly connected with the connecting shaft, and finally, the other bogie wheel is arranged at the other end of the connecting shaft.

As shown in fig. 5-8, in order to make the connecting shaft pass through the bogie wheel suspension 16 and be fixedly connected with it, the other side of the connecting shaft is provided with a shaft shoulder 17, and a positioning ring 18 is arranged on the connecting shaft and limited by the shaft shoulder. The mounting of the bogie wheels on both sides is therefore slightly different, and the other side requires a positioning ring to be mounted before the sealing ring is fitted, as shown on the left side of fig. 4.

The specific installation of the pair of loading wheels is as shown in fig. 4, wherein two sealing rings in the figure are divided into a left sealing ring and a right sealing ring, and one side of each sealing ring is in contact with the side wall of a sealing ring accommodating groove of the inner end cover; the other side of the left sealing ring is axially limited by a positioning ring 18, the positioning ring is arranged on the connecting shaft and limited by a shaft shoulder 17, and thus the sealing ring is limited between the inner end cover on the left side and the positioning ring 18 and is tightly contacted with the inner end cover to form sealing; and the other side of the right sealing ring is limited by an annular bulge 14 on the connecting shaft.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
