When the axle box rubber packing 3 does not include roof liner plate 33, i.e. two rubber blanket unit split settings, the He of the first rubber blanket 31
Second rubber blanket 32 realizes rubber single pad by the small guide table 11 of side frame 1 with the block (not shown) for being arranged at adapter 2
Member it is horizontal, longitudinal direction and vertically position with being connected.
On the other hand, as shown in figure 9, adapter 2 has four supporting legs 24 positioned at transverse ends and longitudinal both ends, along horizontal stroke
It is the installation sky for being connected with side frame 1 and axle box rubber packing 3 to the space between relative two supporting legs 24 and the body of adapter 2
Between, and the installing space is c-type mounting groove 25.In the various embodiments described above, two longitudinal terminal surfaces of the first rubber blanket 31 and adapter 2
22 contacts, the second rubber blanket 32 contact with two transverse end surfaces 23 of adapter 2.
Because above-mentioned adapter 2 has the two c-type mounting grooves 25 that are distributed opposite to each other of longitudinal direction, and the bottom surface of the mounting groove 25 is along vertical
To distribution, therefore, longitudinal terminal surface 22 is the bottom surface of mounting groove 25, and transverse end surface 23 is the two sides of mounting groove 25, i.e. axle box rubber
The first rubber blanket 31 and the second rubber blanket 32 of rubber cushion 1 are connected in the mounting groove 25, and after clamping, the first rubber blanket 31 is by two
The bottom surface of mounting groove 25 is spacing, spacing by the two sides of corresponding mounting groove 25 with second rubber blanket 32 of one end positioned at longitudinal direction,
