Description

1

The invention relates to railway transport and relates to the construction of the vehicle chassis, namely, the communication units of the axlebox wheelset with the frame of a two-axle vehicle.

The purpose of the invention is to increase the driving characteristics.

FIG. 1 shows a uniaxial vehicle; in fig. 2 - axle box seal with the axis of the wheel pair; in fig. 3 is a diagram of the position of wheel pairs with axle boxes when fitting a vehicle into a curved section of the track; in fig. 4 - swinging rod; in fig. 5 - the mechanism of rotation of the wheelset.

A rail vehicle contains a bush 1, which with the help of a bracket through the rubber metal sleeve 2 and the axis 3 is connected to the swing rod 4. The swing rod 4 with the help of axis 5 connects the frame bracket 6, on the other hand the case of the axle box 1 with eyelets 7 connects to the leash 8. The leash 8 is connected with a finger 9 to a thrust 10 mechanism for longitudinal movement of the axle box and using a finger 11 and rubber shock absorbers 12 to connect with an auxiliary link 13, which with a finger 14 connects to the frame . The spring 15 of the axle suspension with its middle part rests on the body of the axle box and is connected with one side to the axle bracket and the other to the frame of the vehicle with the help of pendulous bolts 16 and prismatic supports 17. The bush 1 with a spherical bearing 18 is mounted on the axis of the wheel pair 19. The spherical surface of the bearing thrust sleeve 20 on the axis of the wheel pair 19 with the collar 21 on the axle box cover 22 creates a seal of the other axle link.

The vehicle operates as follows.

When fitting a biaxial vehicle to a curved section of the track, the wheel sets must be turned so that their axes are directed toward the center of the radius of the curved section of the track (Fig. 3).

The reversal of the wheel sets is made by longitudinal movement of the axle boxes. The axle boxes on the inner side of the arc of the curvilinear section come closer together, and on the outer side they are moved apart by

vehicle loads arising from the passage of a curved section of the track, and transfers the load to the body of the axle box 1, which, through the bearing 18, transfers this load to the wheel pair119.

The spring 15, fixed on the case of the axle box 1 with only one end, through the pin bolt 16 and the prismatic support 17 connected to the bracket 6, easily moves together with the axle box body, while retaining its elastic damping properties.

When the body of the axle box 1 is moved, the axis of the wheel pair 19 due to the spherical bearing 18 rotates unhindered from the axle box of the axle box. In this case, the spherical sealing surface of the bearing thrust bearing 20 with a radius (Fig. 2), whose center coincides with the center of rotation of the spherical bearing, also rotates in the axle box along with the axis of the wheel set, retaining the specified sealing gap. The constancy of the gap provides favorable conditions for the operation of the sealing element located on the top of the axle box, thereby increasing the durability and reliability of the axle sealing element.

Claims (3)

1.The rail vehicle containing the frames, through an elastic element, is supported on the axle boxes of at least one wheel set, which are connected to the frame brackets on the one hand by means of the elastic link, which is equipped with a mechanism for turning the wheelset in the horizontal plane, which includes a hinge connected to the shackle and a leash, which are respectively hingedly connected to the frame and to the other side of one of the axle boxes, while a bond brackets and axle box frame is formed as a vertically disposed rod whose ends elastically supported on the respective brackets. 2. The means according to claim 1, characterized in that the elastic element is made in the form of a spring, the middle part connected to the axle box, and the ends by means of hinged links - with an axle box bracket and an additional frame bracket. 3. The means according to claim 1, characterized in that the bearing of each axle box and the interconnecting surfaces of its stop ring and the cover are spherical with the same curvature. 20 nineteen t nineteen   SFfs sTsjr, S FIG. 2 Phage.Z X FIG L
