  • Patent number: 7316436
    Abstract: A differential wheel mounting for replacing a standard railroad axle assembly having a wheel seat portion which includes a sleeve having several sliding surfaces fixedly mounted over the wheel seat portion of the axle, a railroad wheel with a running surface for contacting a rail and a plain bearing member detachably mounted to the railroad wheel. The plain bearing member has non-metallic bearing surfaces that mate with the sliding surfaces on the sleeve so that the bearing member and the attached wheel are laterally confined on the sleeve while being rotatable about the sleeve. The plain bearing member sustains both radial and thrust loads during normal operation of a railroad car.

  • Patent number: 6623057
    Abstract: A railroad car wheelset has an axle with one wheel (14A) rigidly attached. This wheel is permitted to rotate by means of journal bearings either on the extreme ends of the axle or inboard of each wheel location. At the other wheel, the axle has smooth surface and a self-lubricating bearing (54) is provided as a part of a hub on the axle. The hub is integral with the axle or press fit thereon. The axle has a boss for preventing the independently rotating wheel from migrating laterally out of proper alignment. A self-lubricating thrust bearing (32) is located between this boss and the side of the wheel to eliminate any possible galling between the two moving surfaces.

  • Patent number: 6598920
    Abstract: A railroad car wheelset (10) has an axle (12) with one wheel rigidly attached as in conventional railroad practice. This wheel (10) is permitted to rotate by means of journal bearings either on the extreme ends of the axle (12) or inboard of each wheel location (14A and 14B). At the location of the other wheel, the axle (12) is provided with a smooth surface and a self-lubricating bearing (24) is provided as a pant of a hub (20) on the axle (12). The axle (12) shaft is provided with a boss (18) or other means of preventing the independently rotating wheel from migrating laterally out of proper alignment A self-lubricating thrust bearing (32) is located between this boss (18) and the side of the wheel to eliminate any possible galling between the two moving surfaces. A removable retainer plate (46) is located on the other side of the independently rotating wheel to prevent the wheel from moving laterally in that direction.

A removable retainer plate is located on the other side of the independently rotating wheel. Adjacent the removable retainer plate is an electrical contactor. The bearings can be comprised of a lubricant coating permanently bonded to the bearing surface of the hub. Latch elements are pivotally secured to the other wheel and engagable with locking elements operatively secured to the axle. A second wheelset has an independently rotatable wheel locked to the axle automatically in one direction.

  • Patent number: 5884956
    Abstract: A modified railroad wheel and axle assembly used to replace conventional railroad wheel and axle assemblies whereupon one end of a railroad axle assembly is machined to receive a modified railroad wheel assembly thereon. The other end of the railroad axle assembly has a conventional railroad wheel member press fit thereon in a non-rotatable condition. The invention is operable to allow one of two spaced railroad wheel members on a railroad axle assembly to be slip rotatable thereon to reduce wear and tear on a railroad wheel member and the railroad rail members on which the railroad wheel member is tracking.

  • Patent number: 4599032
    Abstract: A rolling base assembly for truck cranes which allows movement of the truck crane under load-carrying conditions. The device comprises a fixed chain installed along the centerline of a flatbed trailer. A rolling base, having outboard roller housing assemblies, is caused to crawl along the fixed chain by means of motor driven sprocket devices attached to the rolling base. The roller housing assemblies are designed to move along the standard I-beam construction of a flatbed truck.

  • Patent number: 4575145
    Abstract: Differential mounting for railroad wheels includes an axle with a wheel fitted on one end to rotate with the axle and a second wheel carried adjacent the opposite end of the axle and mounted to rotate relative to the axle. The axle has a raised wheel seat with an axial length approximately the same as the hub of the second wheel which is generally rectangular in cross-section. Fillets define the inboard and outboard ends of the raised wheel seat and a steel sleeve is fitted over the raised wheel seat and includes an annular flange portion shaped to engage the outboard axle fillet. A collar carried within the sleeve engages the inboard fillet. Pressure plates are disposed on the inboard and outboard ends of the sleeve and include opposed stainless steel thrust bearing surfaces contiguous to the annular side faces of the wheel hub which are surfaced with a TEFLON composite, bearing material bonded thereto.

  • Patent number: 4420179
    Abstract: A wheel for rail vehicles with at least one disc which is connected to an axle, and with a wheel rim having a tread or surface surrounding the disc, while the rail tread in engagement with the rim tread results in contacting points of the wheel during straight forward drive of the vehicle located on the tread or track of the rails. At least within that region of the rim which contains the above mentioned rail contacting points of the wheel rim the wheel rim is turnably connected to the disc for turning about an imaginary axis located in about the driving direction of the wheel.
