Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in detail.
As shown in Figure 1, the present invention proposes a kind of foundation brake rigging of railway goods train bogie, it comprises two brake beam compositions, 1, two pairs of brake levers 2,3, four brake shoes, 4, two dead lever fulcrums, 5, two lower links 6 and a tie-beam 7.Wherein, two brake beam compositions 1 are arranged in Parallel Symmetric.
Each brake beam composition 1 includes a brake beam frame 11, is fastenedly connected a brake head 12 respectively, is fastenedly connected one end (as shown in Figure 2) of two pillars 13 at the interval, side of brake beam frame 11 at the two ends of brake beam frame 11.Four brake shoes 4 are fastenedly connected respectively on four brake heads 12.
Two lower links 6 are arranged in parallel interval, one end of two lower links 6 and the bottom of first pair of brake lever 2 hinged, the bottom of the other end and second pair of brake lever 3 is hinged.Inner side in the middle part of each brake lever 2,3 is all hinged with the other end of a pillar 13.Wherein, the upper end of first pair of brake lever 2 is hinged respectively by the dead lever fulcrum bearing on a dead lever fulcrum 5 and bolster, forms the fixed end of lever system.The upper end thereof of second pair of brake lever 3, at the two ends of tie-beam 7, forms the travelling end of lever system.A lever connection 71 is fastenedly connected, for transmitting braking force or alleviation power at the middle part of tie-beam 7.
Each brake head 12 all connects one in " U " shape fork 8 (as shown in Figure 3) by a groove, the open end of fork 8 is provided with the mounting hole 81 be connected with the flap seat of truck side frame, brake head 12 is driven to move by fork 8, the friction force that brake beam composition 1 is subject to can be reduced, be convenient to car brakeing or alleviation.
In above-described embodiment, each brake beam frame 11 all adopts i shaped steel to make, and can improve the intensity of brake beam frame 11.As shown in Fig. 2, Fig. 7, cut formation one circular arc transition 111 in the bottom at brake beam frame 11 two ends respectively near the position of wheel, the center of gravity that brake beam can be made to form 1 is positioned at the position away from wheel, thus is conducive to brake beam composition 1 alleviation.
In above-described embodiment, as Figure 1 and Figure 4, each lower link 6 all adopts forging and stamping machine-shaping.The through hole 61 of multiple circle is respectively arranged with, for regulating first pair of brake lever 2 and the articulated position between second pair of brake lever 3 and two lower links 6 at the two ends of each lower link 6.
In above-described embodiment, as shown in Figure 1, shown in Figure 5, each dead lever fulcrum 5 is provided with the through hole 51 of multiple circle, when wheel and brake shoe 4 produce abrasion, for regulating the distance between first pair of brake lever 2 and two dead lever fulcrum seats.
