Latest Patents
One of his latest patents is a method and apparatus for reducing vibrations transmitted to a vehicle from a wheel unit. This innovation addresses the vibrations generated by wheel units, employing a low pulsating operation that simulates actual vehicle operating conditions. The design takes into account the mass moment of inertia of the wheel unit and rotating components, such as the hub and brake disc. The wheel unit is mounted on a balancing spindle in a measuring apparatus to determine the mass and angular location of balancing weights. The vibrations are measured at speeds that correspond to typical travel speeds of vehicles. Additionally, a loading mechanism applies force to the tire tread surface to simulate roadway conditions effectively.
Another significant patent is a method and apparatus for balancing rotors. This invention considers position inaccuracies of attachment surfaces for components that possess mass on a rotor, such as crankshafts with crankpins. The differences between ideal and actual positions of each attachment surface are determined and factored into the balancing procedure, enhancing the accuracy of rotor balancing.
