In, when especially turning, cause side frame 1 and adapter 3 stuck due to gapless between small guide table 12 and the second notch 32, from
And guarantee rail vehicle normally travel.
Further, as seen in figs. 8-10, axle box rubber packing 2 includes the upper liner plate 21 and lower liner plate 22 being vertically distributed,
Therebetween it is connected with rubber layer 23, wherein upper liner plate 21 includes first horizontal segment 211 and two first tilting sections tilted down
212, two first tilting sections 212 are located at the longitudinal both ends of the first horizontal segment 211；Lower liner plate 22 includes the second horizontal segment
221 are located at longitudinal two of the second horizontal segment 221 with two second tilting sections 222 that tilt down, two second tilting sections 222
End；Therefore, upper liner plate 21, lower liner plate 22 and rubber layer 23 are splayed configuration structure.
In the present embodiment, due to the presence of two vertical tilting sections, so that the axle box rubber packing 2 has lateral, Zong Xianghe
The rigidity in vertical three directions, so as to improve the stability of rail vehicle operation.In actual use, by adjusting tilting section
The area and thickness of angle and tilting section and horizontal segment between horizontal segment enable to the axle box rubber packing 2 to have difference
Longitudinal stiffness and transverse stiffness, thus cross force and longitudinal force that buffer size is different, so that the axle box rubber packing 2 has

Structure avoids re-working side frame 1.
At this point, in conjunction with Fig. 6 it is found that the longitudinal size of drawing strickle guide top plate 111 be greater than first horizontal segment 211 longitudinal size, because
This, the area that above-mentioned set-up mode cooperates drawing strickle guide top plate 111 and axle box rubber packing 2 reduces, and is equivalent to axle box rubber packing 2
Effective active area reduces, and therefore, leads to the reduction of its rigidity, since the longitudinal both ends of the axle box rubber packing 2 have tilting section,
Longitudinal rigidity is still larger, and therefore, the set-up mode that above-mentioned drawing strickle guide top plate 111 is abutted with first horizontal segment 121 leads to axle box rubber
The lateral stiffness of pad 2 reduces.
Based on this, as shown in fig. 6, the both ends of axle box rubber packing 2 transversely protrude from the side frame guide 11, i.e. its transverse direction
