IPC: F16D65/095
Filed: 1998-03-20
Abstract: PROBLEM TO BE SOLVED: To avoid uneven wear of a pad so as to enhance durability and heat resistance of a piston portion, by attaching a reinforcement member on a reverse face of a back plate stretching along the longitudinal direction thereof and pressing the reverse face of the reinforcement member by the piston. SOLUTION: A brake block 1 is pressed by a piston 4 through a reinforcement member 11 at braking. The brake block 1 tries to warp due to the difference between coefficients of linear thermal expansion of a back plate 3 and a pad 2 by the frictional heat generated at this time. However, the strength and rigidity of the brake block 1 is enhanced by a reinforcement member 11 provided along the longitudinal direction of the back plate 3, inhibiting deformation of the brake block 1. Accordingly, uneven wear of the pad 2 due to braking is prevented. A portion of frictional heat at braking is conducted to the back plate 3 from the pad 2, transmitted to the piston 4 via the reinforcement member 11, and heat is radiated during this process.  Temperature rise of the piston 4, and moreover the temperature rise of hydraulic fluid is prevented, and the durability of a piston seal member is increased.
