Tread produces remission effect.
With reference to Figure 10, combine Figure 21, Figure 22, illustrate that bolster of the present invention composition inner chamber is through sky
The specific implementation process of weight valve connecting branch.For ensureing that bare weight valve connecting branch 27 can be smoothly
Through the inner chamber of bolster framework 8.2, the one side in bolster framework 8.2 is provided with for bare weight valve
The areole 23 that connecting branch 27 passes, areole 23 in waist circle hole shape, oval hole 23
Length L is 150～160mm, and preferably 157mm, highly H are 65～75mm, preferably 69mm；
Meanwhile, extended internally bottom the wedge groove 8.1 that bolster framework 8.2 two ends are arranged symmetrically with end
Gusset 25, the inner chamber of bolster framework 8.2 is provided with hollow supporting rib 19, hollow supporting rib 19
Two ends are outward extended with middle gusset 26, and middle gusset 26 extends to two end gussets 25
Between, thus form the gap 21 passed for bare weight valve connecting branch 27；Further, intermediate ribs
Plate 26 is less than 37mm, the width in gap 21 with length S1 of end gusset 25 lap
Degree S2 is 30～40mm, preferably 35mm.So bare weight valve connecting branch 27 one end is passed through
The oval hole 23 of bolster framework 8.2 one side penetrates into the inner chamber of bolster framework 8.2, passes through
The gap 21 between middle gusset 26 and end gusset 25 in bolster framework 8.2 inner chamber,
Eventually arrive at outside one end of bolster framework 8.2, it is achieved this bolster composition disclosure satisfy that bare weight valve
Connecting branch is through the function of its inner chamber.
Meanwhile, the lower position in oval hole 23 is welded with fixing bare weight valve connecting branch 27
The bolster supporting plate 24 of one end, one end inner chamber lower plane of bolster framework 8.2 is welded with fixing sky
The interior bearing 8.7 of weight valve connecting branch 27 other end.It addition, interior bearing 8.7 and outer support
8.8 are respectively welded at bolster framework 8.2 with the inner chamber lower plane of one end and bolster framework 8.2
In upper plane, outer support 8.8 props up for the fixing outside being connected with bare weight valve connecting branch 27
Pipe.
