An impact mechanism device for a hand power tool comprises at least one impact mechanism including at least one driven cylinder and at least one piston driven in an axial direction by the at least one driven cylinder via a cam mechanism, and at least one planetary gearing configured to drive the at least one driven cylinder and the at least one piston. The at least one piston is positioned at least partially inside the at least one driven cylinder.

Impact mechanism device

Percussion unit, especially for a rotary hammer and/or percussion hammer, comprising a control unit which is designed for open-loop and/or closed loop control of a pneumatic percussion mechanism, and at least one operating condition sensor unit. According to the disclosure, the control unit is designed to detect at least one percussion mechanism parameter depending on measurement values of the operating condition sensor unit.

Percussion unit

A percussion unit for a rotary hammer and/or percussion hammer includes a control unit that is configured for open-loop and/or closed loop control of a pneumatic percussion mechanism. In at least one operating state in which the control unit changes from an idle mode to a percussion mode, the control unit is configured to adjust at least one operating parameter temporarily to a starting value.

The invention is based on a handheld power tool device, having at least one safety mechanism, which intervenes in an uncontrolled blocking situation, and which has a sensor unit. It is proposed that the sensor unit is provided for directly detecting at least one orientation parameter of a handheld power tool.

Handheld power tool device

The invention relates to a hand-held power tool, especially a rotary hammer and/or chisel hammer. The hand-held power tool is provided with a vibration dampening unit having a first absorber mass unit with a first vibration dampening direction and at least one second absorber mass unit with a second vibration dampening direction. The hand-held power tool in particular has the first vibration dampening direction of the first absorber mass unit disposed as substantially parallel to the second vibration dampening direction of the second absorber mass unit.

Hand-held power tool

The invention relates to a wobble drive of a hand-held machine tool, particularly a drilling or chipping hammer, having a drive shaft, a wobble bearing disposed on the drive shaft, and a wobble plate supported on the wobble bearing. At least two wobble fingers having wobble finger axes being provided on the wobble plate. The invention provides that the axes of the wobble fingers form an angle different from 180&#xb0;.
