Title: Edgar Hetteen: Innovator in Multi-Surface Vehicle Technology
Introduction
Edgar Hetteen is a notable inventor based in Grand Rapids, MN (US), recognized for his contributions to vehicle technology. He holds five patents, showcasing his innovative spirit and dedication to improving vehicle design and functionality.
Latest Patents
One of Hetteen's latest patents is a suspension and drive mechanism for a multi-surface vehicle. This tracked vehicle is designed to produce a ground pressure of no more than 3 psi by increasing the number of contact points on the inner surface of the track. The stiffness of the track is carefully selected to minimize bowing between the idler wheels or rollers, ensuring that the track remains substantially straight. This design enhances the efficiency of power transfer to the track. The drive sprocket is positioned above the ground, simplifying the design while effectively transmitting power to the tracks and preventing derailment. The track is maintained in a constant state of tension on the driver sprocket and roller, further reducing the risk of derailment. The vehicle's undercarriage features torsion axles and sealed bearings, which contribute to lower maintenance requirements. Components of the undercarriage do not necessitate constant greasing and cleaning of the idler wheels. Additionally, the track is beveled to prevent damage to surfaces. The drive sprocket is equipped with roller sleeves that accommodate changes in the pitch line of an elastomeric flat track, ensuring smooth operation. It also includes scrapers and conical shields for self-cleaning, effectively removing debris from the sprocket area.
