Caliper brake
Disclosed is a caliper brake. The caliper brake includes a carrier having a pair of pad plates installed therein to be movable forward and backward; a caliper housing slidably installed at the carrier, and provided with a finger bent downward and configured to pressurize each of the pair of pad plates; and an elastic member installed at the caliper housing and configured to elastically support a lower end portion of each side of the carrier, wherein the lower end portion of each side of the carrier in contact with the elastic member is formed to be inclined.
1. A caliper brake comprising:
a carrier having a pair of pad plates configured to be movable forward and backward and having a pair of arms;
a caliper housing slidably installed at the carrier, and having a finger, which is bent downward and configured to pressurize each of the pair of pad plates; and
an elastic member installed at the caliper housing and configured to elastically support a lower end portion of each of the pair of arms,
wherein the caliper housing has a cylinder in which a piston configured to pressurize the pair of pad plates is arranged to be movable forward and backward in an axial direction of the piston at a rear portion of the caliper housing, and
wherein the lower end portion of each of the pair of arms in contact with the elastic member has an inclined surface inclined upwardly away from the pair of pad plates in the axial direction of the piston.
2. The caliper brake of claim 1 , wherein the lower end portion is inclined in a direction in which the caliper housing slides.
3. The caliper brake of claim 1 , wherein the inclined surface of the lower end portion includes:
a flat portion formed in a direction in which the caliper housing slides; and
an inclined portion, and
wherein the inclined portion has a curved line shape.
4. The caliper brake of claim 1 , wherein the inclined surface of the lower end portion includes:
a flat portion formed in a direction in which the caliper housing slides, and
an inclined portion, and
wherein the inclined portion has a straight line shape.
5. The caliper brake of claim 1 , wherein the lower end portion of each of the pair of arms is arranged and configured such that a distance between a first end of the inclined surface and an axis of the piston is different from a distance between a second end of the inclined surface, which is opposite to the first end in the axial direction of the piston, and the axis of the piston.
6. The caliper brake of claim 4 , wherein the inclined portion curvedly extends further from the straight line shape at a predetermined angle of greater than 0 degree.
7. The caliper brake of claim 1 , wherein the inclined surface has an inclination angle increasing toward the finger.
