Abstract
The utility model discloses a multi-working-condition brake block which comprises a metal sheet and a friction block. A thermal insulating layer is arranged between the metal sheet and the friction block. The metal sheet, the friction block and the thermal insulating layer are attached into a whole. The face, facing a brake disc, of the friction block is provided with a first arc grooving set and a second arc grooving set. Arc grooving in the first arc grooving set and arc grooving in the second arc grooving set are U-type grooves. The grooving direction of the arc grooving in the first arc grooving set is radiated externally in the radial direction by using the circle center of the brake disc as the center, and the arc protruding direction is the same as the rotating direction of the brake disc. The grooving direction of the arc grooving in the second arc grooving set is radiated externally in the radial direction by using the circle center of the brake disc as the center, and the arc protruding direction is opposite to the rotating direction of the brake disc. The depth of the arc grooving in the first arc grooving set is larger than that of the arc grooving in the second arc grooving set.
