Patent number: 10851860Abstract: A disc brake rotor and hub assembly for a heavy-duty vehicle. The disc brake rotor and hub assembly includes a hub portion. The hub portion is receivable on, and rotatable about, an axle spindle of a heavy-duty vehicle. A rotor portion includes a disc segment, a mounting segment and a cylindrical sleeve segment connecting the disc segment to the mounting segment. A flange portion connects with the rotor portion and separately with the hub portion. Optionally, the rotor portion connects directly to the hub portion. A smallest inner dimension of the rotor portion is greater than a largest outer dimension of the hub portion to facilitate removal of the rotor portion without removing the hub portion from the axle spindle.Type: GrantFiled: May 22, 2018Date of Patent: December 1, 2020Assignee: Hendrickson USA, L.L.C.Inventors: Jeffrey R. Wittlinger, Jay D. White, Jason Andler, Keith M. Ernenwein, Matthew P. Karich, Jeffrey S. Morris, Sri Satya Teja Kakarla, Chiran Shamser Jbr

Patent number: 10800205Abstract: A hub for a heavy-duty vehicle and for mounting a wheel for relative rotation comprises a substantially cylindrical body having axially opposite end portions and a longitudinal central axis. Each of a pair of bearing receiving bores is formed in the cylindrical body at a respective axially opposite end portion of the cylindrical body. A circumferential envelope has an outer diameter and is formed on the cylindrical body about one of the pair of bearing receiving bores. A flange extends radially outward from the cylindrical body at a location between the pair of bearing receiving bores. A barrel portion of the cylindrical body extends between the flange and the circumferential envelope and has an outer diameter. The hub provides sufficient strength and minimizes weight by incorporating specific longitudinal profiles and ratios and/or relationships of various dimensions of the barrel portion 104.Type: GrantFiled: November 29, 2017Date of Patent: October 13, 2020Assignee: Hendrickson USA, L.L.C.Inventors: Jason Andler, Dane Gregg, Keith Ernenwein, Jeff Wittlinger, Sri Satya Teja Kakarla

Patent number: 8419029Abstract: An air-ride beam-type axle/suspension system for a heavy-duty vehicle with a gross axle weight rating of greater than 23,000 lbs./axle includes a pair of transversely spaced beams. Each one of the beams includes inboard and outboard sidewalls. A large diameter axle extends between and is rigidly connected to the beams via a pair of axle-to-beam connections. Each one of the axle-to-beam connections includes a sleeve having an increased thickness rigidly connected to the axle and the beam. Each sleeve is formed with at least a front and a rear window located between the beam sidewalls. The inboard and/or outboard edges of the sleeve windows are spaced relatively far from the beam sidewalls. The sleeve windows are asymmetrically angled with respect to the horizontal centerline of the axle at design ride height. The axle/suspension system reduces weight while maintaining desired stiffness and durability of the axle/suspension system.Type: GrantFiled: March 9, 2011Date of Patent: April 16, 2013Assignee: Hendrickson USA, L.L.C.Inventors: Brett L. Muckelrath, Donald R. Hester, Sri Satya Teja Kakarla, James J. Patterson, Brian R. Anderson, R. Scott Fulton, Keith D. McComsey, Brian R. Morris

Publication number: 20120193490Abstract: A shock mount support assembly for a shock absorber of a suspension assembly of an axle/suspension system includes a shock support bracket formed with an opening. A fastener is disposed through the opening in the shock support bracket and an eyelet of the lower end of the shock absorber to loose-fit the shock support bracket to the shock absorber, and to the suspension assembly beam in a transverse direction. The shock support bracket includes at least one transversely elongated or oversized opening that aligns with an opening formed in the beam. A fastener is disposed through the pair of aligned openings in order to loose-fit attach the shock support bracket to the beam. During assembly, the eyelet fastener is tightened first drawing the shock support bracket transversely outboardly. The fastener disposed through the shock support bracket-to-beam attachment is tightened, rigidly attaching the shock support bracket to the suspension assembly.Type: ApplicationFiled: January 27, 2012Publication date: August 2, 2012Applicant: HENDRICKSON USA, L.L.C.Inventors: Brett L. Muckelrath, Keith D. McComsey, Sri Satya Teja Kakarla, Ryan J. Lippincott, James J. Patterson, R. Scott Fulton
