The specific embodiment
As shown in Figure 1, the integrated brake equipment of railway goods train bogie reinforcement that the utility model embodiment provides comprises preceding brake beam 1, front brake lever 2, preceding drag chain 3, two-way self-regulated stroke reinforcement brake cylinder 4, back drag chain 5, back brake lever 8, back brake beam 9, brake shoe 10.
Wherein, preceding brake beam 1 is isosceles triangular structure with back brake beam 9, is arranged symmetrically in the both sides of truck bolster 21 (referring to Fig. 7).Preceding brake beam 1 is provided with pillar 6 with back brake beam 9, and this pillar 6 is positioned on the midperpendicalar position of above-mentioned equicrural triangle.The preceding brake beam 1 of design-calculated and afterwards brake beam 9 stable and reliable structure, stressed being evenly distributed like this.Preceding brake beam 1 is installed with slide block 7 (referring to Fig. 2) with the right ends of back brake beam 9.Slide block 7 is embedded in the chute 26 on the truck side frame 25 (referring to Fig. 7).Right ends slide block 7 (referring to Fig. 3) inboard of brake beam 1 and back brake beam 9 before brake shoe 10 is installed in.When current brake beam 1 moves with respect to chute 26 with slide block 7 on the brake beam 9 of back, can drive brake shoe 10 and be close to or leave wheel 20 (referring to Fig. 6).
Referring to Fig. 2, Fig. 7, on the pillar 6 of brake beam 1, an end of the upper end of front brake lever 2 and preceding drag chain 3 was hinged before the lower end of front brake lever 2 was hinged on.The other end and the preceding fixed pivot seat 22 on the truck bolster 21 of preceding drag chain 3 are hinged.
Referring to Fig. 2, Fig. 7, the lower end of back brake lever 8 is hinged on the pillar 6 of back brake beam 9, and the upper end of back brake lever 8 is hinged with an end of back drag chain 5, and the back fixed pivot seat 23 on the other end of back drag chain 5 and the truck bolster 21 is hinged.The upper end of brake lever 8 also is provided with the pin-and-hole 24 that can link to each other with hand brake device in the back.When the two-way self-regulated stroke of pneumatic type reinforcement brake cylinder 4 can't be worked, can spur back brake lever 8 through hand brake device, and then drive the braking of miscellaneous part completion wheel 20.Arrow B illustrates the application of force direction of hand brake device among Fig. 2.In addition, also can pin-and-hole 24 be arranged on the upper end of front brake lever 2.
Referring to Fig. 1, the front end of two-way self-regulated stroke reinforcement brake cylinder 4 is hinged on the middle part of front brake lever 2, and the rear end of two-way self-regulated stroke reinforcement brake cylinder 4 is hinged on the middle part of back brake lever 8.Referring to Fig. 4, two-way self-regulated stroke reinforcement brake cylinder 4 comprises brake cylinder 13, step-up system 12 and two-way self-regulated stroke apparatus 11.If step-up system 12 is not set, the brake-force transmission that brake cylinder 13 produces will be dwindled during to brake shoe 10, and the demand of braking force in the time of can not satisfying vehicle parking is the amplification of realization braking force, and the utility model is integrated 1 step-up system 12 on brake cylinder 13.Wherein, two-way self-regulated stroke apparatus 11 is that the patent of CN200920227667.X has been done detailed presentations at application number, repeats no more.As shown in Figure 4, step-up system 12 comprises piston 16, is filled with the cavity of fluid medium 17.Piston 16 areas of braking force mouth are greater than piston rod 18 areas of braking force input end, and the principle of utilizing the fluid pressure to transmit is amplified braking force, and the adjustment of braking force enlargement ratio can realize with the area ratio of piston rod 18 through changing piston 16.In addition, also can realize the amplification of braking force through mechanical booster mechanism.
When brake shoe 10 or wheel 20 abrasion, generally can cause the gap increase between brake shoe 10 and the wheel 20; When brake shoe 10 or wheel 20 renew, generally can cause the gap between brake shoe 10 and the wheel 20 to be reduced.This moment is long or shortening through the automatic accent of two-way self-regulated stroke apparatus 11, can keep the piston stroke of brake cylinder 13 to be stabilized in the dimension limit of regulation.As shown in Figure 5, the boss of control stalk 15 leaves gap A with the limiting block 14 that is installed on the cylinder cap 19, and the dosage of regulating the cavity inner fluid medium 17 of step-up system 12 can determine the size of gap A, thus the piston stroke length of control brake cylinder 13.
A kind of integrated brake equipment principle of work of railway goods train bogie that is adapted to be mounted within on the bogie truck that the utility model embodiment proposes is following:
Implement the wind glancing impact when vehicle, the piston rod 18 that brake cylinder 13 protracts is passed to piston 16 through extrusion fluid medium 17 with the braking force pressure, under the situation that pressure equates; Piston 16 areas are greater than piston rod 18 areas; Thereby the amplification braking force, this moment, piston 16 moved forward under the propelling movement of fluid medium 17, drove two-way self-regulated stroke apparatus 11 and moved; Move thereby drive control stalk 15, make itself and the limiting block 14 that is installed on the cylinder cap 19 produce relative displacement.After gap A eliminates; When piston 16 continued to move, 14 of limiting blocks can stop that control stalk 15 continues to move, and moves thereby trigger two-way self-regulated stroke apparatus 11; Two-way self-regulated stroke apparatus 11 can be transferred long or shortening automatically according to the size of taking turns watt gap; And give back brake lever 8 with force transmission, give front brake lever 2 through two-way self-regulated stroke reinforcement brake cylinder 4 with the application force back transfer simultaneously, before front brake lever 2 drives with back brake lever 8 brake beam 1 with after brake beam 9 in the chute 26 of truck side frame 25, slide; Drive brake shoe 10 and be adjacent to wheel 20, thereby realize car brakeing.
When vehicle is implemented when hand braking; With the hand brake device pulling back brake lever 8 that is connected in the brake lever 8 upper end pin-and-holes 24 of back; Give front brake lever 2 through two-way self-regulated stroke reinforcement brake cylinder 4 with force transmission simultaneously; Brake beam 1 slided in the chute 26 of truck side frame 25 with back brake beam 9 before front brake lever 2 drove with back brake lever 8, drove brake shoe 10 and was adjacent to wheel 20, thereby realize car brakeing.
The integrated brake equipment of railway goods train bogie according to the utility model provides has the following advantages:
(1), simple and compact for structure, easy to assemblyly easily effectively reduce dead weight of vehicle, improved the load-carrying ability of vehicle;
(2), planar friction pair and pivoting friction be secondary few, driving efficiency is high, friction drag is low, can effectively improve vehicle braked efficient and improve release of brake bad;
