Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in detail.
As shown in Figure 1, the utility model proposes a kind of brake rigging of railway goods train bogie, it comprises two5, two lower links of individual brake beam 1, two pair of brake lever 4, two dead lever fulcrum of 2,3, four brake shoes of composition6 and a tie-beam 7. Wherein, two brake beam compositions 1 are Parallel Symmetric layout.
Each brake beam composition 1 includes a brake beam frame 11, is fastenedly connected respectively one at the two ends of brake beam frame 11Brake head 12, is fastenedly connected one end (as shown in Figure 2) of two pillars 13 at a side interval of brake beam frame 11. FourIndividual brake shoe 4 is fastenedly connected respectively on four brake heads 12.
Two lower links 6 are parallel interval to be arranged, the bottom of one end of two lower links 6 and first pair of brake lever 2 is hinged,The bottom of the other end and second pair of brake lever 3 is hinged. The inner side at each brake lever 2,3 middle part all with a pillar13 the other end is hinged. Wherein, the upper end of first pair of brake lever 2 is respectively by dead lever fulcrum 5 and a bolsterOn dead lever fulcrum bearing hinged, form the stiff end of lever system. The upper end of second pair of brake lever 3 is hingedAt the two ends of tie-beam 7, form the end that moves about of lever system. Be fastenedly connected a brake bar at the middle part of tie-beam 771, for transmitting brake force or alleviation power.
Each brake head 12 is all connected and one is 8 (as shown in Figure 3) of " U " shape fork by a groove, the opening of fork 8Mouth end is provided with the installing hole 81 being connected with the flap seat of truck side frame, drives brake head 12 to move by fork 8,Brake beam composition 1 frictional force being subject to be can reduce, car brakeing or alleviation are convenient to.
In above-described embodiment, each brake beam frame 11 all adopts i shaped steel to make, and can improve brake beam frame 11Intensity. As shown in Fig. 2, Fig. 7, cut respectively and form one near the position of wheel in the bottom at brake beam frame 11 two endsCircular arc transition 111, can make the center of gravity of brake beam composition 1 be positioned at the position away from wheel, thereby be conducive to brakingBeam composition 1 is alleviated.
In above-described embodiment, as Figure 1 and Figure 4, each lower link 6 all adopts forging and stamping machine-shaping. At eachThe two ends of lower link 6 are respectively arranged with the through hole 61 of multiple circles, for regulating first pair of brake lever 2 and second pairArticulated position between brake lever 3 and two lower links 6.
In above-described embodiment, as shown in Figure 1, shown in Figure 5, on each dead lever fulcrum 5, be provided with the logical of multiple circlesHole 51, in the time of wheel and brake shoe 4 generation abrasion, for regulating first pair of brake lever 2 and two dead lever fulcrum seatsBetween distance.
In above-described embodiment, as shown in Figure 1 and Figure 2, each pillar 13 is all vertical with brake beam frame 11, eachThe end of post 13 is provided with the installing hole being connected with a brake lever, and the axis of installing hole is along brake beam frame 11 lengthDirection arranges. The angle that has ensured like this longitudinal center's face of pillar 13 and longitudinal vertical guide of brake rigging isZero, can prevent that brake beam frame 11 is subject to Lateral Force and is offset.
As shown in Figure 6, Figure 7, when the utility model uses, two brake beams compositions 1 are arranged in to two-wheeled between 9,Each is taken turns brake beam composition 1 of 9 corresponding layout, thereby realizes single shoe brake. When braking, brake beam composition 1Center of gravity away from wheel, fork 8 is in a certain angle with the plumb line of brake beam composition 1, transmits the braking of brake force and drawsWhen bar 71 is subject to brake holding load left, brake force is delivered on second pair of brake lever 3 by tie-beam 7, and secondBrake lever 3 is promoted to two lower links 6 and move right, two lower links 6 promote first pair of brake lever 2 and will act onPower is delivered on two pillars 13 of right side brake beam composition 1, under two pillars 13 on right side and the effect of two forks 8The brake beam that promotes right side forms 1 entirety and moves right. Two pillars 13 on left side brake beam composition 1 are subject to leftBrake force, the brake beam that promotes left side under the effect of left side two pillars 13 and two forks 8 forms 1 entirety to left movement,Thereby make recline respectively corresponding wheel tread of four brake shoes 4 produce braking effect.
When alleviation, the center of gravity of brake beam composition 1 is away from wheel, and fork 8 is certain with the plumb line of brake beam composition 1Angle, the brake bar 71 that transmits brake force is subject to alleviation power to the right, and alleviation power is delivered to second by tie-beam 7On brake lever 3, second pair of brake lever 3 pulls two lower links 6 to left movement, and two lower links 6 pull firstTo brake lever 2 and alleviation power is delivered on two pillars 13 of right side brake beam composition 1, at right side two pillars 13With under the effect of two forks 8, promote right side brake beam and form 1 entirety to left movement. On left side brake beam composition 1 twoPillar 13 is subject to alleviation power to the right, promotes the brake beam in left side under the effect of left side two pillars 13 and two forks 8Form 1 entirety and move right, produce remission effect thereby make four brake shoes 4 leave respectively corresponding wheel tread.
The various embodiments described above are only for illustrating the utility model, and wherein structure, the connected mode etc. of each parts are all passableChange to some extent, every equivalents of carrying out on the basis of technical solutions of the utility model and improvement, all should not arrangeExcept protection domain of the present utility model.
