Title: Christian Hartmann: Innovator in Torque Sensing Technology
Introduction
Christian Hartmann is a notable inventor based in Emskirchen, Germany. He has made significant contributions to the field of torque sensing technology, holding a total of 5 patents. His innovative work has been instrumental in advancing the capabilities of various mechanical systems.
Latest Patents
One of Hartmann's latest patents is a magnetoelastic torque sensor featuring a magnetized sleeve as the primary sensor. This torque sensor utilizes the measuring principle of inverse magnetostriction to measure torque on a shaft. The design includes a magnetized sleeve with at least two circumferential portions that are magnetized in opposing directions. These portions interact in a contactless manner with measuring coils to acquire accurate measured values. The sleeve is constructed from a non-magnetic carrier sleeve part, onto which the magnetized portions are attached through deposition welding of a ferromagnetic material.
Another significant patent is the traction mechanism tensioning unit for a traction mechanism drive in motor vehicles. This unit comprises a housing that contains a hydraulic tensioner. The hydraulic tensioner features a cylinder element that is rigidly connected to the housing, with an axially moving piston inside. A compression spring generates an axial tensioning force on the piston within a compression chamber. The hydraulic tensioner is fluidly connected to a pressurized medium supply line via a pressure control valve, ensuring a constant pressurized medium pressure in the compression chamber.
