  • Publication number: 20250083473
    Abstract: Wheel hub assemblies and methods of producing a wheel hub assembly are provided. The wheel hub assembly includes a wheel hub fastened to a wheel of a vehicle, the wheel hub having a rotor mounting surface facing an inboard direction, a disc brake rotor having a mounting surface attached to the rotor mounting surface, the mounting surface facing an outboard direction and a bearing mounted inside the wheel hub. The rotor mounting surface is machined after installation of the bearing inside the wheel hub and fixation of the bearing to the wheel hub by a snap ring such that a runout of the rotor mounting surface is less than or equal to 30 ?m.

  • Publication number: 20250012318
    Abstract: A wheel bearing assembly is provided. The wheel bearing assembly includes an outer ring, a wheel hub rotating relative to the outer ring, the wheel hub including a hub flange, an inboard surface of the hub flange facing an outboard surface of the outer ring and spaced a gap apart from the outboard surface of the outer ring in an axial direction, a plurality of rolling elements rotatably coupling the outer ring and the wheel hub, a first spacer disposed between the inboard surface of the hub flange and the outboard surface of the outer ring, and a second spacer disposed between the first spacer and the outboard surface of the outer ring. At least a portion of the first spacer and at least a portion of the second spacer are disposed in the gap.

  • Patent number: 11999207
    Abstract: A spring assembly for a non-rail wheeled or tracked vehicle is provided. The spring assembly includes a piston, and a sleeve with variable thickness. The sleeve is made from an unreinforced synthetic elastomeric material and being free of reinforcing fibers. The sleeve is coupled with a plurality of end components and defines a deformable pressure vessel, and the deformable pressure vessel supplies a support force.

  • Patent number: 11433726
    Abstract: A method for forming an air spring for a vehicle including a frame coupled to the air spring includes heating an elastomeric base material to a melting point of the elastomeric base material, thereby forming a melted elastomeric base material, forming a sleeve from the melted elastomeric base material, the sleeve being substantially free of textile reinforcing fibers, and engaging the sleeve with end components, the sleeve and the end components defining a deformable pressure vessel, where the deformable pressure vessel supplies a supporting force.

  • Patent number: 11351859
    Abstract: The electronic IWE actuator includes an electric motor, a worm gear connected to the electric motor, a ball ramp including a worm wheel configured to engage with the worm gear, a clutch ring configured to engage with a wheel hub of the vehicle, and a shift fork configured to engage with the clutch ring and the ball ramp and move linearly in a direction along an axis of the wheel hub in response to a rotation of the ball ramp. The clutch ring is configured to engage with the wheel hub in response to a rotation of the worm gear in a first direction, and disengage from the wheel hub in response to a rotation of the worm gear in a second direction that is opposite to the first direction.

  • Patent number: 11021187
    Abstract: A steering knuckle is used in a motor vehicle and is typically positioned adjacent a front wheel thereof. The steering knuckle includes a central portion, a steering knuckle arm, an upper portion and a lower portion. The steering knuckle arm, the upper portion and the lower portion may each be contoured with full or partial roulette contoured surfaces (i.e., surfaces defined by roulette curves), and the upper portion may transition from a hollow lower portion to a solid upper portion defining an I-beam. A dual-beam horizontal support is formed in the central portion. The steering knuckle is formed from a casting process, and the roulette curvature of the steering knuckle arm, the upper portion and the lower portion provide draft to the surfaces of the steering knuckle which are perpendicular to the parting line of the casting mold, allowing the steering knuckle to be easily removed from the casting mold.
