Abstract

Equipped with an electromechanical brake: a piston (30) which is mounted in a brake caliper housing (20) in such a way that it is movable forwards and backwards in an axial direction and moves forwards in the axial direction at the time of performing a braking operation in order to press a friction lining (11, 12) which is provided to clamp a disc (10); an actuator (50) that provides a rotational force to move the piston (30); a spindle (40) which is threaded to the piston (30) and rotates by a torque transmitted by the actuator (50) to move the piston (30) axially forwards and backwards; and a guide element (60) which is integrally attached to the brake caliper housing (20) and coupled to the piston (30) to limit the rotation of the piston (30) and to guide the forward and backward axial movement of the piston (30), wherein the guide element (60) is arranged outside the spindle (40), wherein the guide element (60) has a container shape that receives and surrounds the piston (30), and wherein a coupling section (41) is formed on the spindle (40), which is supported in the axial direction by a support section (62) of the guide element (60), and the coupling section (41) has a shape extending radially from the spindle (40) and projecting from it, wherein the support section (62) of the guide element (60) comprises: a receiving section (63) having a shape that receives the coupling section (41) of the spindle (40), and which is formed on the guide element (60), and which supports the coupling section (41) of the spindle (40), which is received in the receiving section (63), on the front side of the coupling section (41); and a bearing (64) which is installed within the receiving section (63) of the guide element (60) between the coupling section (41) of the spindle (40) and an inner surface of the brake caliper housing (20) at the rear of the coupling section (41) and supports the coupling section (41) of the spindle (40) in such a way that the coupling section (41) is rotatable within the brake caliper housing (20) at the rear of the coupling section (41).
