Abstract: An improved bracket and bushing combination for the end of a walking beam forming a part of a wheel suspension system of a large truck. The bracket is a hollow housing having an end opening and side holes for receiving bolts which are threaded into the ends of a bushing after the bushing has been inserted into the housing through the end opening. The bushing is carried at one end of a walking beam, and the bushing is held in the housing by mounting elements which are secured in place over the end opening by bolts and nuts in partial surrounding relationship to the bushing. In one form of the bushing, the shaft of the bushing is concentric to the resilient core member surrounding the shaft. In another form of the bushing, the shaft is eccentric to the core member.

Abstract: A hinge pin of segmented form with its components in threaded connection with one another. The components of the pin include tool receiving surfaces engageable by a wrenching tool for applying torque during assembly and disassembly of the pin. The components are provided with male and female threads.

Abstract: A hinge pin including two substantially identical sections which when assembled form a cylindrical sleeve. Each section has a first end having a cross-section greater than a semi-circle which tapers along its length to a second end having a cross-section less than a semi-circle. When the two sections are joined together, they form a cylindrical sleeve for use as a readily removable hinge pin. Ready removal is effectuated by sliding one section away from the other along their tapered lengths, the taper enabling the average diameter of the sleeve to decrease as the two sections are so slid apart.
