Title:
DISC-BRAKE DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/124150
Kind Code:
A1
Abstract:
A disc-brake device (1) comprises a brake disc (2), a brake lining (3), and a brake caliper (4). The brake lining (3) includes a friction member (9) and a base plate (10) that supports the friction member (9). When a plurality of bolt holes (7) are projected in the direction of an axle (5) onto a rear surface (13) of the base plate (10), a border (16) passes through the area of the projected plurality of bolt holes (7). The brake caliper (4) includes an inner-side pressing surface (17) that imparts a load to an inner-side area (14), and an outer-side pressing surface (18) that imparts a load to an outer-side area (15). The load imparted from the inner-side pressing surface (17) to the inner-side area (14) is different from the load imparted from the outer-side pressing surface (18) to the outer-side area (15). This makes it possible to minimize stress exerted on bolts while also minimizing local temperature increases in the brake disc.
