上記交換の際に従来は交換作業が困難であった。Such a brake shoe is known to be one of the largest consumable parts among general brakes. In other words, since the tread brake originally originated from a cast iron brake shoe, even though synthetic brake wheels and sintered alloy brake wheels are now common, the method of attaching the brake shoe to the brake head is a conventional method. According to. Therefore, when the friction material is consumed or the component is damaged, a part to be replaced, that is, a part to be discarded is large. Therefore, improvement is required in terms of processing cost and material cost. Further, in the case of the above replacement, it has been conventionally difficult to perform the replacement operation.

As shown in (b), a friction material (2) is fixed to one surface of a base (15), and a mounting plate (16) for a brake head is provided at the center of the other surface. The structure of the sintered alloy brake shoe is the eleventh
As shown in FIGS. 1 (a) and 1 (b), a friction material (2) is fixed to a reinforcing plate (1) via an adhesive layer (4), and the reinforcing plate (1) is fixed to a base metal (15). Further, a mounting plate (16) is provided similarly to the above. Note that both FIGS. 10 and 11 (17)
Indicates the receiver. In such a conventional synthetic brake shoe or sintered alloy brake shoe, the front part shown in the above drawings is a part which is replaced as a consumable and is discarded, which is a problem in terms of cost. In addition, the base metal was sometimes damaged due to its structure.
本発明はこれに鑑み種々検討の結果、これら問題点を
解消した制輪子および制輪子頭を開発したものである。The present invention has been made in view of the above and, as a result of various studies, has developed a brake shoe and a brake shoe head which have solved these problems.

And two substantially trapezoidal grooves (9) for inserting a removal jig in the same direction as the above. Further, the torque receiving pin (8) pressed by the spring (7) corresponds to X in FIG. 3 shown in FIG.
As can be seen from the sectional view taken along the line X ', a through hole (10) is formed at one end of the spring (7) in contact with the spring (7), and when the torque receiving pin (8) is installed, the through hole (10) is formed. A jig insertion hole (11) is provided in the thickness direction of the brake head (5) extending from (10). FIG. 4 shows a state in which the pin (8) is pressed toward the brake shoe side by the spring (7), and its tip is fitted into the concave portion (3) of the reinforcing plate (1).

易に取り外すことが可能となる。In order to remove such a brake shoe, a pin removing jig (12) having a tapered tip end as shown in FIG. 5 and a substantially U-shaped flat surface shown in FIG. First, as shown in FIG. 7, first, the above-mentioned removal jig (12) is inserted into the jig insertion hole (11) of the bracelet head (5) as shown in FIG. Insert one end on the taper side. At this time, the tapered surface of the punching jig (12) also penetrates the through hole (10) of the pin (8) at the same time, and the pin (8) moves against the pressing force of the spring (7) by the tapered surface. So that the tip of the pin (8) is in the recess (3) of the reinforcing plate (1).
, The brake shoe becomes slidable in the direction of the pair of substantially U-shaped grooves (6). Then, as shown in FIG. 8, the parallel tips of the removal jig (13) are inserted into two grooves (9) having a substantially trapezoidal cross section of the brake shoe head (5) corresponding to one brake shoe. I do. The inserted jig (13) is slid on the reinforcing plate (1) as shown in FIGS. 9 (a) and (b) so that the projection (14) at the tip thereof comes out of the slot on the opposite side. The jig (13) is pulled out by engaging the projection (14) with the edge of the reinforcing plate (1). In this manner, the reinforcing plate (1), that is, the brake shoe can be easily removed.
