A car truck including a first side frame, a second side frame, and an underslung steering assembly connected to the first side frame and the second side frame, configured to reduce, inhibit, minimize, and/or prevent truck hunting and warping.

Underslung steering arm assembly

A vehicle truck includes a first side frame, a second side frame, a bolster, a first yaw separator connected to the first side frame, and a second yaw separator connected to the second side frame. Each yaw separator includes two steering arms and an arm connector assembly. The yaw separators are configured to alter yaw movement of the truck that leads to truck hunting.

Various embodiments provide a stabilizing transom. Various embodiments provide a vehicle truck such as a railroad car truck including a first side frame, a second side frame, a bolster, and a stabilizing transom connected to the first side frame and the second side frame and configured to reduce, inhibit, minimize, and/or prevent truck hunting and warping.

Stabilizing transom

A railroad car articulated split friction wedge assembly including first and second articulated friction wedges, wherein the first friction wedge includes a first body, a first decoupling insert, a first pivot member pivotally moveable with respect to the first body and the first decoupling insert, and a first wear pad removably attached to the first pivot member, and wherein the second friction wedge includes a second body, a second decoupling insert, a second pivot member pivotally moveable with respect to the second body and the second decoupling insert, and independently of the first body and the first pivot member, and a second wear pad removably attached to the second pivot member, which in combination provide required damping, provide high warp restraint, reduce binding, and enable lateral decoupling.

A railroad car truck including a first side frame, a second side frame, a bolster, and a first plurality of warp restraints, each first warp restraint configured to prevent warping of the bolster relative to the side frames. Various embodiments include opposing bearings of each warp restraint that engage each other.

Railroad car truck with warp restraints

A railroad car truck including a first side frame, a second side frame, a bolster, and a plurality of warp restraints that are configured to prevent warping of the bolster relative to the side frames.

A vehicle spring type brake shoe key for connecting a brake shoe to a brake head, wherein the brake shoe key includes a body or shank and a head integrally formed with the body or shank, and wherein the key has a reduced mass head, an alternative configuration head, a surface treatment, or two or more of these modifications that reduces the likelihood that the head will weaken and/or break off the body of the brake shoe key,

A strap tensioning buckle apparatus provides a ratchetless strap tensioning buckle apparatus for tensioning straps utilized in tying down objects. The ratchetless strap tensioning buckle apparatus has a base having a first end and a second end, a linkage pivotally attached to the base at a midpoint thereof, a handle having a first end and a second end, the handle having a shaft at the first end thereof for holding a loop of strap, the shaft further rigidly connecting the handle to the linkage, the handle pivoting via the linkage and moving the shaft in an arc from a first position to a second position, wherein moving the shaft from the first position to the second position tightens the strap and locks the strap in place.

A wheel chock is constructed from metallic material has an elongate primary body construction. The primary body construction has a &#x3a0;-shaped transverse cross-section formed by an upper C-shaped channel construction and a lower planar basal construction. The basal construction has U-shape that extends orthogonally relative to the C-shape of the channel construction. The &#x3a0;-shaped transverse cross-section bears and distributes stress imposed on the primary body construction. The C-shaped channel construction preferably includes a series of apertures for reducing weight and controlling elastic response of the primary body construction. Among these apertures are edge-based apertures, arm-based stress relief slots, and aligned apertures having sequentially decreasing diameters.
