Patent number: 9539708Abstract: A hand-held power tool has a motor, a tool holder, and a percussion mechanism disposed between the motor and the tool holder in the drive train. The percussion mechanism includes a first shaft and a second shaft. A magnetically conductive ring gear is connected to the first shaft. An inner wall of the ring gear is eccentric to an axis of the second shaft. A magnetically conductive impeller is connected to the second shaft and is arranged to rotate within the ring gear. The impeller is spaced from the ring gear by a first air gap in a first position while being spaced from the ring gear by a second air gap in a second position, the first air gap being smaller than the second one. A magnet array is arranged coaxially to the second shaft. A magnetorheological fluid fills a cavity between the ring gear and the impeller.Type: GrantFiled: October 17, 2012Date of Patent: January 10, 2017Assignee: Hilti AktiengesellschaftInventors: Alexander Hoop, Albert Binder, Michael Wierer, Dieter Profunser

Patent number: 9469019Abstract: A control method according for an impact wrench includes ascertaining whether the impact wrench applies an impact when the drive shaft rotates in a lower speed range. The speed of the drive shaft then is increased to a higher speed range as a function of an ascertained impact during the rotation in the lower speed range.Type: GrantFiled: April 19, 2010Date of Patent: October 18, 2016Assignee: Hilti AktiengesellschaftInventors: Dieter Profunser, Peter Brugger, Jochen Kuntner

Patent number: 9381626Abstract: A hand-held power tool, in particular in the form of a hammer drill or an impact screwdriver, is disclosed. The tool has a tool receptacle attached to an output shaft for receiving a tool, where the output shaft may be set into a rotating and partially percussive motion by a drive shaft and a tangential striking mechanism. The tangential striking mechanism has an anvil allocated to the output shaft and a hammer allocated to the drive shaft. The hammer can be moved axially under the application of the force of a spring and a sliding block guide, and can be struck against the anvil with the rotation of the same. The sliding block guide has a helical control contour which has a first slope in a first section and a second slope in a second section, where the first and second slopes are different.Type: GrantFiled: April 27, 2012Date of Patent: July 5, 2016Assignee: Hilti AktiengesellschaftInventors: Dieter Profunser, Laurent Wahl

Patent number: 8950508Abstract: A handheld power tool, including a tool socket on a drive shaft for purposes of holding a tool, the drive shaft executing a rotating and partially tangentially striking movement using a tangential striking mechanism drivable by a drive. The tangential striking mechanism has an anvil associated with the drive shaft and a hammer associated with the drive, movable with respect to each other so as to strike each other axially when under the effect of the force of at least one first spring, and to strike each other tangentially when the anvil and the hammer are rotated. The hammer has a main mass, and an extra mass that is under the effect of a second spring couplable to the main mass.Type: GrantFiled: November 25, 2011Date of Patent: February 10, 2015Assignee: Hilti AktiengesellschaftInventors: Alexander Hoop, Hans Boeni, Dieter Profunser, Peter Brugger

Patent number: 8833484Abstract: A control method for a power tool and a power tool is disclosed. The control method has an operating mode and a safety mode. In the operating mode, a motor drives a tool receptacle in a rotating manner. In the operating mode, the motor has a power consumption in the amount of at least an operating value. The safety mode is triggered if a sensor device detects a rotational blockade of the tool receptacle. In the safety mode, a clutch that is switchable by electrical signals located in the drive train between the motor and tool receptacle is periodically opened and closed and a power consumption of the motor is reduced as compared to the operating value.Type: GrantFiled: October 25, 2011Date of Patent: September 16, 2014Assignee: Hilti AktiengesellschaftInventors: Albert Binder, Dieter Profunser, Alexander Hoop
