Publication number: 20240116318Abstract: Apparatuses, systems, and methods for determining and verifying operational states of fifth wheels. Certain methods for determining the operational state of the fifth wheel may include sensing, with at least one sensor, magnetic flux caused by a magnet on a movable component movable to lock the fifth wheel to a kingpin of a towed vehicle and determining an end position of the movable component based on the magnetic flux. The end position of the movable component is then compared to a threshold position and an operational state of the fifth wheel is determined based on the comparison of the end position of the movable component to the threshold position.Type: ApplicationFiled: December 20, 2023Publication date: April 11, 2024Applicant: Fontaine Fifth Wheel CompanyInventors: Carl Gaufin, Michael Shane Wolfe

Publication number: 20230347694Abstract: A fifth wheel system includes a fifth wheel configured to couple to a kingpin of a towed trailer such that vibrations are generated when the fifth wheel couples to the kingpin. A sensor in operative association with the fifth wheel and configured to sense the vibrations and generates vibration data. A controller receives the vibration data and processes the vibration data to detect a presence or an absence of a predetermined vibration component that occurs when the fifth wheel properly couples to the kingpin. An indicator indicates proper coupling of the fifth wheel to the kingpin when the predetermined vibration component is present.Type: ApplicationFiled: July 10, 2023Publication date: November 2, 2023Applicant: Fontaine Fifth Wheel CompanyInventors: Carl Gaufin, Ryan Fechner

Patent number: 10591009Abstract: A vehicle spring brake having a parking brake housing that defines a parking brake chamber and a service brake housing that defines a service brake chamber. A flexible membrane separates the parking brake chamber from the service brake chamber and flexes into and out of the service brake chamber based upon a pressure differential between an air pressure in the parking brake chamber and an air pressure in the service brake chamber. A pushrod extends out of the service brake housing when the flexible membrane flexes into the service brake chamber and retracts into the service brake housing when the flexible membrane flexes back out of the service brake chamber. A control valve controls the pressure differential to thereby control movement of the flexible membrane and the pushrod.Type: GrantFiled: February 16, 2018Date of Patent: March 17, 2020Assignee: TSE Brakes, Inc.Inventors: Carl Gaufin, Ryan Fechner
