Embodiment Construction

[0044] The best mode for carrying out the present invention will be described in detail below with reference to the drawings.

[0045] figure 1 A brake disc pad 10 according to an embodiment of the present invention is shown. The brake disc friction pad 10 is used in a disc brake of a high-speed railway vehicle, and a plurality of disc brake pads 10 are arranged along the rotation direction of the disc brake (not shown). Such as figure 1 As shown, the brake disc friction block 10 has a base plate 12 and a brake lining 14 mounted on the base plate 12 .

[0046] The substrate 12 is configured as a flat plate having an elongated shape extending in a predetermined direction when viewed in plan, and both ends in the longitudinal direction form approximately triangular shapes. The base plate 12 is provided in such a manner that its longitudinal direction is along the rotational direction of the brake disc.

[0047] Such as figure 2 As shown, the substrate 12 is provided with...

Abstract

The present invention holds an elastic member located near a lining in an elastic condition with the temperature rise of the lining. This disc pad comprises the elastic member 40 arranged between a base plate 12 and the lining 14 for permitting the movement of the lining 14 in the direction of approaching the base plate 12 while permitting the tilting displacement of the lining 14, when thrust against a brake disc, and a heat transfer suppressing member 44 arranged between the elastic member 40 and the lining 14. A body 34 of a rivet 30 has an abutting portion 34a for abutting on the base plate 12 and an intermediate portion 34b arranged between the abutting portion 34a and a head 32 and having a smaller diameter than the abutting portion 34a. A gap width S1 between the abutting portion 34a of the rivet 30 and a cylindrical portion 26 is smaller than a gap width S2 between the head 32 of the rivet 30 and the lining 14.

Description

technical field [0001] The invention relates to a brake disc friction block used in a disc brake of a high-speed railway vehicle. Background technique [0002] Conventionally, as a brake disc friction pad used in a disc brake of a railway vehicle, as disclosed in the following Patent Document 1, there is generally known a brake pad that is pressed onto a brake disc and a brake pad that supports the brake pad. structure of the substrate. As described in the literature 1, such as Figure 5 As shown, a recess 83 is formed on the base plate 82, and an annular elastic member 84 is disposed on the recess 83, and the brake lining 81 is inserted into the recess 83 to clamp the elastic member 84 to the brake lining. 81 and the substrate 82. When the brake lining 81 is pressed against the brake disc 85 during the braking operation, the brake lining 81 is displaced relative to the base plate 82 .
