Motor-driven hand-held tool unit has clutch wheel with dogs protruding into intermediate space(s) formed by clamp surfaces and clamp body that is stopped when motor is switched off

摘要

The tool unit has a drive motor for the tool and a brake between them to brake to tool after the motor is switched off. The brake is an idler with a first idler body (1) driven by the motor with a cylindrical clamp surface (7), a concentric second idler body (2) with a second clamp surface (8) and a prismatic clamp body (6) between the clamp surfaces that can be clamped between the surfaces under friction. A clutch wheel with dogs (5) protruding into the intermediate space(s) formed by the clamp surfaces and body is stopped when the motor is switched off..
