Patent number: 11865862Abstract: A disc brake hub and rotor assembly for a heavy-duty vehicle. The disc brake hub and rotor assembly includes a hub receivable on and rotatable about an axle spindle of a heavy-duty vehicle. A rotor is connectable with the hub for rotation with the hub. The rotor includes a disc segment, a flange mounting segment, and a cylindrical sleeve segment connecting the disc segment and the flange mounting segment. A flange is connectable with the flange mounting segment and separately with the hub. The flange mounting segment of the rotor has an inboard facing surface at least part of which is for engaging head portions of wheel studs. The inboard facing surface is substantially planar and free of wheel stud clearance reliefs. A transition region is located between the flange mounting segment and sleeve segment and is also free of wheel stud clearance reliefs.Type: GrantFiled: October 22, 2020Date of Patent: January 9, 2024Assignee: Hendrickson USA, L.L.C.Inventors: Jay D. White, Matthew P. Karich

Patent number: 11204070Abstract: A brake component positioning assembly that is removably connectable to a component of a heavy-duty vehicle. The brake component positioning assembly enables a brake system component to be positioned away from a wheel end of the heavy-duty vehicle to allow removal or servicing of at least one component of a wheel end assembly or the vehicle brake system. In one embodiment, the brake component positioning assembly includes a base block disposed in a cutout of a torque plate. A positioning block slidably engages one or more guide pins received by or disposed through the base block. A positioning bolt threadably engages the positioning block, whereby upon rotation of the positioning bolt, the positioning block and brake system component are positioned away from the bottom block and wheel end. Components of the brake component positioning assembly can be removably connected to each other.Type: GrantFiled: May 16, 2018Date of Patent: December 21, 2021Assignee: Hendrickson USA, L.L.C.Inventors: Jay D. White, Jeffrey R. Wittlinger, Dhawal P. Dharaiya, Matthew P. Karich

Patent number: 11022192Abstract: A tone ring attachment for a disc brake rotor. The disc brake rotor has a disc portion that includes a plurality of circumferentially-spaced lugs. Each one of the lugs has a groove. A discrete tone ring body has a plurality of bosses. Each one of the bosses is receivable in a respective one of the grooves in the lugs. A dart projection extends from at least one of the bosses. The dart projection engages a respective one of the lugs to inhibit relative axial movement and relative rotational movement in at least one direction between the tone ring and the disc brake rotor. A tab is formed on at least one of the bosses. The tab is engageable with a portion of the lug to inhibit relative rotational movement in a second direction opposite the first direction between the tone ring and disc brake rotor.Type: GrantFiled: November 26, 2019Date of Patent: June 1, 2021Assignee: Hendrickson USA, L.L.C.Inventors: Jay D. White, Dhawal P. Dharaiya, Matthew P. Karich

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

Publication number: 20190047535Abstract: An air actuated brake system for use on a heavy-duty vehicle having a frame. Each of a first pair of air actuated brake assemblies is mounted to a first axle supported by the frame. Each of a second pair of air actuated brake assemblies is mounted to a second axle supported by the frame. A source of pressurized air is provided. Valve structure is in fluid communication with the source of pressurized air. The valve structure is located substantially central relative to each of the air actuated brake assemblies. Conduits of substantially equal length and/or volume fluidly connect the valve structure with the first pair of air actuated brake assemblies and with the second pair of air actuated brake assemblies to actuate the air actuated brake assemblies at substantially the same time.Type: ApplicationFiled: August 9, 2018Publication date: February 14, 2019Inventors: R.
