Patent number: 10994581Abstract: A clamp group for a vehicle leaf spring suspension is disclosed. The clamp group secures a longitudinally disposed, leaf spring at separate and distinct locations, between which the leaf spring is undamped and spaced away from the top and bottom pads of the clamp group. Shear stress is reduced and the spring remains active throughout its length.Type: GrantFiled: August 9, 2016Date of Patent: May 4, 2021Assignee: HENDRICKSON USA, L.L.C.Inventors: Michael J. Keeler, Dmitriy Enrikovich Rubalskiy, Scott Allen Massa, Jeffrey R. Zawacki, Michael P. Bloink, Damon E. Dilworth, Matthew J. Van Meter

Patent number: 10611206Abstract: An automatic air suspension control system is provided for use in combination with a vehicle having a non-driven rear axle, a driven rear axle, and an air suspension associated with the rear axles to apply a load to each of the rear axles. The air suspension control system is programmed to maintain the load applied to the non-driven rear axle at a level that is less than the load applied to the driven rear axle until the load applied to the driven rear axle is equal to a threshold amount. The threshold amount may be equal to the maximum load that may be legally applied to the driven rear axle or some lower level. There may be no load applied to the non-driven rear axle prior to the load on the driven rear axle reaching the threshold amount or may be a non-zero amount.Type: GrantFiled: March 12, 2014Date of Patent: April 7, 2020Assignee: Hendrickson USA, L.L.C.Inventors: Jeffrey R. Zawacki, Michael J. Keeler, Ashley Thomas Dudding

Patent number: 9933337Abstract: A wireless sensor for a wheel end assembly of a heavy-duty vehicle is provided. The wheel end assembly includes a wheel hub and a hub cap mounted on the wheel hub. The sensor includes mounting means disposed in the hub cap. Sensing means are mounted on the mounting means to sense at least one condition of the vehicle. A processor is mounted on the mounting means and is electrically connected to the sensing means to process data from the sensing means. Communication means are mounted on the mounting means and are electrically connected to the processor to communicate the processed data to a user. An electrical energy storage device is mounted on the mounting means and is electrically connected to the sensing means, the processor and the communication means, enabling the sensor to be independent from the vehicle power supply. The sensor also accommodates components of a tire inflation system.Type: GrantFiled: September 11, 2015Date of Patent: April 3, 2018Assignee: Hendrikson USA, L.L.C.Inventors: Jay D. White, Jeffrey S. Morris, Keith M. Ernenwein, Matthew Karich, Jeffrey R. Zawacki

Patent number: 8128394Abstract: Tooling assemblies for interfacing with interchangeable molds are provided, each with a tooling body for mounting to a platen of a press of an injection molding machine and for receiving an interchangeable mold block. Interchangeable mold blocks are also provided for forming articles. A series of fasteners fasten each mold block to one of the tooling bodies. Alignment systems are oriented within a perimeter of the mold block to permit expansion of the mold block relative to the tooling body to accommodate varying rates of thermal expansion of the tooling body and the mold block. Methods for assembling a mold, molding an article and interchanging a mold with interchangeable mold blocks are also provided.Type: GrantFiled: March 26, 2009Date of Patent: March 6, 2012Assignee: Delta Engineered PlasticsInventors: Brian L. Desmith, Wilfried Mozer, Jeffrey R. Zawacki
