Abstract

A parking brake is disclosed, comprising a brake-actuating electric motor (1), a brake actuating output shaft (2) driven by said electric motor and extending along a second axis (A2), a brake-actuating linkage (4) that is adjustably arranged parallel to a first axis (A1) that substantially extends perpendicularly to the second axis (A2), and a drive connection from the brake-actuating output shaft (2) to the brake-actuating linkage (4). The drive connection is configured in the form of a cam-type cam disk or gate guide (3) that translates the rotation of the brake-actuating output shaft (2) into a translational movement of the brake-actuating linkage (4) through an adjusting element (5) that is guided along a surface (F) of the cam disk or gate guide 93) forming a radial profile. The motor axis (A3) of the brake-actuating electric motor (1) extends substantially perpendicular to the second axis (A2).
