Disc brake having an electromechanical actuator

A disc brake (1) for vehicles, the disc brake comprising:

• two brake linings (4, 4a) and an electromechanical actuator (2) for applying the two brake linings to a brake disc (46) via a rotary lever (7),
• wherein the electromechanical actuator (2) comprises:
• an actuator housing (5),
• a cam disc (10) arranged in the actuator housing (5) on a shaft (6), and a tappet (8) cooperating with the cam disc (10),
• wherein a spring (20) surrounds the tappet (8), the spring (20) being axially arranged with a first end stop on the actuator housing (5), the spring (20) being axially arranged with a second end stop on the tappet (8) and the spring (20) fixes the tappet (8) axially and radially in a starting position (S) of the rotary lever (7), in which the tappet (8) extends parallel to an axial axis (a) of the electromechanical actuator,
• wherein the second end stop of the spring bears against the tappet in the axial direction, such that the spring is compressed axially in response to axial movement of the tappet.

• wherein the electromechanical actuator (2) comprises:
• an actuator housing (5),
• a cam disc (10) arranged in the actuator housing (5) on a shaft (6), and
• a tappet (8) extending along an axial axis (A) and cooperating with the cam disc (10), wherein, tangentially along the tappet (8), a first spring (30) is arranged,
• wherein opposite the first spring (30), tangentially along the tappet (8), a second spring (31) is arranged,
• wherein the first spring (30) and the second spring (31) are configured to retain the tappet (8) axially and radially in a starting position (S) of the rotary lever (7).
