Latest Patents

One of Bogdanov's notable inventions is a torque sensor specifically designed for power assist steering systems. This torque sensor effectively senses the applied torque between two relatively rotatable input and output shafts connected via a torsion element. It comprises an input transformer and a rotary transmitter, which is integrally connected to the input shaft for rotation. The rotary transmitter includes multiple transmitter pole segments defined by slots and a transmitter coil that encircles each pole segment. Additionally, a rotary receiver is spaced axially from the rotary transmitter and rotates with the output shaft, providing a robust mechanism for torque sensing.

Another significant patent can be highlighted as the torque sensing apparatus, which is aimed at measuring torque applied to an elongated shaft. This invention utilizes a magnetoelastic element fixed around a portion of the shaft, generating a magnetic field responsive to applied torque. A magnetic member is placed adjacent to this element, facilitated by an alternating power source that drives it into magnetic saturation. This inventive approach features a detector circuit that detects the saturation condition of the magnetic member and provides a corresponding signal indicative of the applied torque.
