Abstract
The utility model provides a novel railway track car brake shoe suspension device. The novel railway track car brake shoe suspension device comprises a brake shoe suspension rod, wherein the upper end of the brake shoe suspension rod is hinged with a pulling rod; a mounting seat is arranged on a car frame; a left suspension rod and a right suspension rod are fixedly connected into a whole; the upper ends of the left suspension rod and the right suspension rod are respectively hinged with the mounting seat through a rotary shaft; the lower ends of the brake shoe suspension rod, the left suspension rod and the right suspension rod are hinged with a brake shoe through a pin shaft; and the left suspension rod and the right suspension rod are positioned on the inner side of the brake shoe suspension rod. According to the novel railway track car brake shoe suspension device, brake shoe suspension adopts two-rod suspension, guide plates are arranged at head parts of two rods, a gap of 1 mm is reserved between each guide plate and the brake shoe suspension rod, and the guide plates are used for limiting swing of the brake shoe suspension rod when a braking operation is performed, so that when the brake shoe is close to a wheel tread, the brake shoe does not swing left and right, is good in stability and does not cause the phenomena of rim braking, partial braking and the like.
Description
Technical field
The utility model relates to a kind of railway track car brake shoe suspension gear.
Background technology
For make rail vehicle can apply brake and alleviation be installed on a whole set of equipment on the rail vehicle, be generically and collectively referred to as railway vehicle brake, the brake shoe suspension type on the current track car in the brake equipment adopts single suspension rod to hang, like this, when the rail vehicle apply brake, easily produce brake shoe stop wheel rim, partially stop, cause wheel wear, the brake shoe unbalance stress produces boss, shortened the service life of brake shoe and wheel, do not possess high speed railway operation demand, waste resource yet, therefore be necessary to improve.
The utility model content
The technical matters that the utility model solves: a kind of railway track car brake shoe suspension gear is provided, brake shoe hangs and adopts two bars to hang, and two club heads are provided with guide plate, leave the gap of 1mm between guide plate and brake shoe suspension rod, during apply brake, guide plate restriction brake shoe suspension rod swings, when the close wheel tread of brake shoe, brake shoe can right not wave, and brake shoe stop wheel rim, the phenomenon such as stop partially can not appear in good stability.
The technical solution adopted in the utility model: railway track car brake shoe suspension gear, comprise the brake shoe suspension rod, described brake shoe suspension rod upper end is hinged with pull bar, described vehicle frame is provided with mount pad, left hanger bar and right hanger bar are fixed with one, described left hanger bar and right hanger bar upper end is hinged by rotating shaft and mount pad respectively, and described brake shoe suspension rod, left hanger bar and right hanger bar lower end are hinged by bearing pin and brake shoe, and left hanger bar and right hanger bar are positioned at brake shoe suspension rod inboard.
Further, described left hanger bar and right hanger bar connect as one by connecting panel, left hanger bar and right hanger bar upper end all are shaped with the pin-and-hole I, and described rotating shaft one end passes the pin-and-hole I, and the rotating shaft other end passes the pin-and-hole II on the mount pad and uses the spring cotter I and packing ring I pinning anticreep.
Further, described mount pad is U-shaped mount pad, and the described rotating shaft other end stretches in the U-shaped groove with spring cotter I and packing ring I pinning anticreep after all passing the pin-and-hole II.
Further, described left hanger bar and right hanger bar upper end all is shaped with guide plate.
Further, the pin-and-hole I inboard of described left hanger bar and right hanger bar upper end all is shaped with boss.
Further, described brake shoe suspension rod, left hanger bar and right hanger bar lower end are by bearing pin and brake shoe is hinged and pin anticreep with spring cotter II and packing ring II.
The utility model advantage compared with prior art:
1, brake shoe hang to adopt two bars to hang, and two club heads are provided with guide plate, and during apply brake, guide plate restriction brake shoe suspension rod swings, and brake shoe just can wigwag motion, and good stability satisfies the operating needs of railway high-speed railway car;
2, avoid occurring brake shoe stop wheel rim, the phenomenon such as stop partially.
