  • Publication number: 20240173840
    Abstract: A hand-held power tool includes a drive motor and a transmission. The drive motor includes a drive shaft. The transmission is operably connected to the drive shaft and is configured to be driven by the drive shaft. The transmission includes at least one transmission cover configured to close the transmission at least in portions. The at least one transmission cover is arranged at least partially between the drive motor and the transmission. At least one motor component assigned to the drive motor projects at least in portions into the at least one transmission cover.

  • Patent number: 11787030
    Abstract: A power tool includes a housing in which a drive unit is arranged, and a tool holder for the detachable holding of a tool insert. The tool insert is configured to be driven percussively and/or rotationally. A sensor unit is configured to detect at least one movement variable, and electronics are configured to control or regulate the power tool. The electronics have a percussion detection unit configured to determine a percussion mode based on at least one movement variable and/or a rotation detection unit configured to determine a rotation of the housing. The electronics control the drive unit based on the determined percussion mode and/or the determined rotation of the housing. The electronics have at least two parameter sets for the percussion detection unit and/or at least two parameter sets for the rotation detection unit. The electronics are configured to select one of the at least two parameter sets.

  • Patent number: 11279016
    Abstract: A system includes first and second power tools that each have a percussion mechanism, a motor, and a transmission. The transmission includes a striking mechanism and is configured to transfer a driving motion of the motor to an insert tool held in a tool holder. The transmission has a guide tube that is identical in some regions along a working axis and accommodates a striker. The guide tube is rotatably coupled to the motor by a first transmission unit. The striker is driven to linearly oscillate by a piston of a second transmission unit. A ratio between a diameter of the tool holder and a diameter of the guide tube is 1.8 times greater in the first power tool than in the second power tool. A striking energy of the second power tool is mechanically reduced compared to a striking energy of the first power tool.
