SPRING ACCUMULATOR BRAKE CYLINDER HAVING AN ELECTRIC MOTOR DISPOSED WITHIN THE ACCUMULATOR SPRING

摘要

The invention relates to an electromechanical tensioning device for vehicle brakes, having a spring accumulator brake piston (8) comprising a spring accumulator brake piston rod (18) for clamping and releasing the spring accumulator brake and disposed in a spring accumulator brake cylinder (4) of a spring accumulator brake and that can be actuated by at least one accumulator spring (10) implemented as a coil spring, and comprising an electric motor (40) for tensioning and/or relieving the accumulator spring (10). According to the invention, the electric motor (40) is radially enclosed by the accumulator spring (10) implemented as a coil spring, and the radial enclosing of the electric motor (40) as seen in the axial direction extends at least over an axial segment of the electric motor (40).
