Abstract: A replaceable replacement spindle assembly for both drive (tractor) axles and trailer axles comprises a spindle and seal ring. The spindle is an elongate cylinder having inner and outer bearing surfaces and a threaded portion at one end. The seal ring is a short annular or tubular component having a circular opening sized to achieve an interference fit on a portion of the spindle adjacent the inner bearing surface. The interfering surfaces of the spindle and the seal ring are complementarily dimensioned and tapered so that the surfaces contact when the spindle is properly positioned in the seal ring. Adjacent the end of the spindle opposite the bearing surfaces and threads is an end region with features such as openings or a channel which receive complementary fasteners such as plugs, short bolts or a through bolt.

Abstract: A fabricated drop axle is described. A pair of axle stub ends is oppositely retained within a saddle having a recess through which accessories can pass.

Abstract: Rail gear may facilitate a vehicle traversing on the rails of a railway. The rail gear may comprise a first rail guidewheel and a second rail guidewheel in rotatable connection with an axle. The rail gear may also comprise a first mount that is restricted from rotating with respect to the axle and a second mount that is configured to rotate with respect to the axle.

Abstract: A railway car axle includes a first stub axle mounted in a rigid hollow sleeve. The first stub axle has opposite inner and outer ends, and the sleeve has a first open end and an oppositely disposed first terminal end. A first bore is defined by a cylindrical wall extending from the first open end to the first terminal end. The first stub axle is journalled in the first bore so as to position the inner end of the first stub axle adjacent the first terminal end and so that the outer end of the first stub axle extends from the first open end. Separate first inner and first outer bearing housings, and corresponding first bearings, are mounted tight to the inner ends of the first stub axle or to outer housing and the first open end of the sleeve respectively so as to allow rotation of the first stub axle relative to the sleeve. A mirror image may be provided for mounting a second stub axle in the sleeve.

Abstract: An axle mounting assembly for a vehicle. The assembly comprises a yoke (24) including a generally U-shaped member defining a slot (26) for receiving an axle with the slot extending vertically and having an upper opening. A member (54) is removable attachable to the yoke to close the opening for removably retaining the axle in the yoke. A block (56) is disposed in the slot and spring biased to effect bearing of the block against the axle for distributing the load between the assembly and other axle mounting assemblies.

Abstract: The invention provides a wheel assembly consisting of first and second spaced apart coaxial wheels. The wheel are mounted on a support structure such that they can rotate relative to one another. A first brake rotor is non-rotatably connected to the first wheel, and a second brake rotor is non-rotatably connected to the second wheel. A brake stator is operable on each rotor to oppose rotation of the two brake rotors simultaneously.

Abstract: A wheel set for rails has a divided axle and two wheels rigidly attached to he respective axle section. The axle sections are interconnected in a force transmitting manner by a clutch for adjusting a differential r.p.m. between the two axle sections. However, the clutch components also permit a relative rotation when the clutch is not energized. The clutch has an inner clutch component and an outer clutch component forming a work gap (7.4) between the clutch components. The work gap extends concentrically to the rotational axis of the shaft and is filled with a magnetizable powder for engaging and disengaging the clutch components which are so mounted to the respective axle section that an axial displacement of the clutch components relative to each other is prevented.

Abstract: Axle assembly for a railway or other types of track riding vehicle including a first axle member fixed to a first wheel to ride on one track and extending longitudinally outwardly from the wheel, with a groove adjacent the outermost end of the axle, a second wheel with a longitudinally, outwardly extending axle shaft fixed at one end to the second wheel where the outer end of the second axle shaft includes a generally cylindrical housing having an open to receive the outermost end of the first axle. A first plate is provided to be received on the open end of the housing and has a central aperture, of diameter generally equal to the diameter of the first axle member, so the first axle member extends therethrough and so the end of the first axle and the groove are located within the housing.

Abstract: A lightweight wheel and axle assembly that reduces unsprung weight thereby improving the ride. The assembly also diminishes hunting and reduces tendencies towards unstable dynamic conditions. The wheel and axle assembly is easily adaptable to conventional three-piece trucks as well as to other truck designs.
