Title: The Innovative Contributions of Johann Kramer
Introduction
Johann Kramer is a notable inventor based in Leonberg, Germany. He has made significant contributions to the field of automotive technology, holding a total of 6 patents. His work focuses on enhancing vehicle safety and performance through innovative designs.
Latest Patents
One of Kramer's latest patents is a bumper arrangement for motor vehicles. This design features a bumper that can be moved between a rest position and an operating position. A spring acts on the bumper, which is prestressed in the rest position. A locking device secures the bumper in both positions, while a control unit operates the locking device based on signals from an accident detection sensor system. When the locking device is disengaged, the spring propels the bumper into the operating position, allowing it to absorb impact loads from relative velocities up to a predetermined limit in a largely elastic manner.
Another significant patent is a damping body designed to mitigate periodically alternating loads. This damping body utilizes a shape-memory alloy material to control the damping process. It can be sintered from metal grains or constructed from multiple perforated sheet-metal layers. The layers are oriented either transversely or parallel to the loading direction and are fully connected. Additionally, a combination of round pins aligned parallel to the loading direction can be employed as a damping body. The design incorporates hollow spaces within the damping body, which helps to reduce multiaxial stress states that could impair damping behavior.
