Publication number: 20240075607Abstract: A handheld work apparatus includes a motor, a transmission shaft, a tool, a guide tube, a housing, and a first anti-vibration element. The motor via the transmission shaft drives the tool. The transmission shaft is received in the guide tube. The motor is disposed in the housing. The tool is disposed on a front longitudinal end of the guide tube. The housing is disposed on the rear longitudinal end of the guide tube. The housing at least partially encompasses the guide tube, wherein the guide tube projects from the housing. The first anti-vibration element is disposed such that it acts in a vibration-decoupling manner between the housing and the guide tube. The first anti-vibration element is disposed on that side of the motor facing the tool. The handheld work apparatus includes a second anti-vibration element connecting the motor to the housing in an at least indirectly vibration-decoupled manner.Type: ApplicationFiled: April 26, 2023Publication date: March 7, 2024Inventors: Johannes Menzel, Lars Robert Kraft, Matthias Maier, Denis Ehrler, Felix Moessinger, Marc Schmid

Patent number: 11279016Abstract: 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.Type: GrantFiled: June 1, 2018Date of Patent: March 22, 2022Assignee: Robert Bosch GmbHInventors: Andre Kurz, Thomas Brinkmann, Lars Schmid, Pascal Schmitz, Hardy Schmid, Patrick Heinen, Jan Koalick
