Title:
電気機械式に切換可能な形状結合式のフリーホイール、このようなフリーホイールを備えた自動車用の電気機械式のブレーキ、及びこのようなブレーキのエアギャップを調整するための方法
Document Type and Number:
Japanese Patent JP5002011
Kind Code:
B2
Abstract:
The invention relates to an electromechanically switchable form-locking freewheel mechanism for preventing an electromechanical brake from releasing. According to the invention, the freewheel mechanism is embodied in the form of an electric motor in which a pivot angle of the armature is limited, the armature is counterbalanced and has a locking element that cooperates with a gear. The invention permits a compactly designed freewheel mechanism that can be integrated into an electromechanical actuating unit of the electromechanical brake. The counterbalancing of the armature equipped with the locking element prevents external accelerations of the freewheel mechanism of the kind that can occur during driving operation of a motor vehicle from exerting a moment on the armature that could switch off the freewheel mechanism. A method for adjusting the clearance of an electromechanical brake is also provided.
