  • Publication number: 20250249713
    Abstract: A rocker body assembly includes a rocker body having a top surface with a hook formed thereon and a bore having an oval cross-section formed through the rocker body. The bore includes a crescent-shaped surface adjacent the hook and a primary surface formed on the top surface. A channel formed in the primary surface extends into the oval cross-section of the bore. A J-bolt having a threaded end and a hook end may be slidably disposed through the bore and channel, with a washer and threaded fastener engaging the threaded end to generate a clamping force securing an axle between the hook of the rocker body and the hook end of the J-bolt. The crescent-shaped surface enables rotational alignment of the J-bolt within the bore to accommodate axles of various sizes and is configured to reduce bending stresses and torque applied to the washer, the J-bolt, and the threaded fastener.

  • Publication number: 20250251011
    Abstract: A high strength J-bolt for a saddle-mount is provided for use in attaching the saddle-mount to an axle of a vehicle. The high strength J-bolt can include a round distal end, a tapered and/or round mid-section, and a hook end with a specified inside bend radius and cross-sectional shape configured to accommodate an increased range of axle sizes. A D-shaped cross-sectional shape can be formed for the hook end to provide for increased contact area with the axle, a larger cross-sectional area, and a higher section modulus along a critical bending axis as compared to a non-critical bending axis to maximize a clamping force that can be applied to the axle and militate against mechanical failure of the high strength J-bolt. A hot forging process can be used to form the shape of the high strength J-bolt.

  • Publication number: 20250001818
    Abstract: A coupling system for a bolster and a clamp assembly of a saddle-mount. The coupling system includes an externally threaded member and an internally threaded member configured to threadably engage the externally threaded member. A lock plate includes an anti-rotation feature, an aperture to receive the externally threaded member, and a slot extending from an edge of the aperture. A receiving member is configured to abut the lock plate and receive the externally threaded member, wherein the receiving member is one of the bolster and the clamp assembly of the saddle-mount. A split lock washer is disposed on the externally threaded member and positioned between the lock plate and one of a head of the externally threaded member and the internally threaded member. The split lock washer cooperates with the lock plate to militate against a rotation of the externally threaded member with respect to the internally threaded member.
