A dead axle of a rail vehicle, a rail vehicle, and a rail transportation system are provided. The dead axle of a rail vehicle includes: an axle body; a running wheel; a guiding frame; a horizontal wheel; and a connecting rod component, including a first transverse pull rod and a second transverse pull rod, where when the rail vehicle turns left, the horizontal wheel cooperates with a rail beam to drive the guiding frame to swing and drive the first transverse pull rod to move together, and the second transverse pull rod is driven by the first transverse pull rod to drive the running wheel to swing to the left, and when the rail vehicle turns right, the horizontal wheel cooperates with the rail beam to drive the guiding frame to swing and drive the first transverse pull rod to move together, and the second transverse pull rod is driven by the first transverse pull rod to drive the running wheel to swing to the right.

The invention relates to a method for producing an axle housing of a vehicle axle, by means of integrally connecting an axle tube (1) to an axle shaft (2) which is positioned on the longitudinal axis (L) of the axle tube, is equipped with bearing surfaces (3) for mounting a vehicle wheel, and has a tube cross-section facing said axle tube (1) which is substantially the same as the tube cross-section of the axle tube. In order to develop a welding method for the production of an axle housing that consists of an axle tube and an axle shaft secured thereto, which method is optimised in terms of the dynamic loads to which the axle housing is typically subjected in a driving operation, the method comprises the following steps: •—arranging the axle tube (1) and the axle shaft (2), with the abutting surfaces of their tube cross-sections positioned coaxially to one another, in a workpiece receiving portion of a welding installation (10), said welding installation additionally comprising an arc welding device (11) and a laser welding device (12) which is operated in parallel, •—continuously miming a weld seam (20) in the peripheral direction of the tube cross-sections, both welding devices (11, 12) being directed, actively and from the outside, onto substantially the same peripheral section of the abutting surfaces, wherein the laser beam (S) meets the outside (14) of the tube at right angles, and intersects the longitudinal axis (L) of the axle tube (1), and •—stopping running the weld seam (20) once this has passed over a peripheral angle of at least 360°. A corresponding axle housing is also disclosed.

A unitized wheelend is provided. The unitized wheelend includes a hub having an inboard side bounded by an oil seal and an outboard side bounded by a retainer releasably coupled to the hub. The unitized wheelend assembly includes an inboard bearing assembly, a spacer, an outboard bearing assembly, and a spindle nut assembly.

A quick replace axle for use on the non-drive axles of a vehicle comprising an outer sleeve and an inner axle wherein the inner axle fits into the outer sleeve and is held in place with a plurality of secure pins. The quick replace axle may also be hydraulic and may include a disk break assembly or a drum break assembly.

A vehicle rigid axle with an axle beam, at the ends of which axle journals or wheel carriers, are arranged, and trailing arms rigidly attached with a spring bracket for supporting an air-suspension bellow, and a method for manufacturing the vehicle rigid axle. An axle beam section extending between the trailing arms, a trailing arm adjoining the axle beam section and the spring bracket are formed by two shell elements connected to each other, which form a hollow body. In an embodiment, the spring bracket is formed by a lower shell element forming an axle beam section extending between the two trailing arms, and the spring bracket is arranged so that the air-suspension bellow mounted on the spring bracket is penetrated by the central longitudinal axis of the axle beam section. Two shell elements made of sheet metal are formed and joined together to form a hollow body.

A spindle for a wheel end assembly includes a first end of the spindle receiving the wheel of a vehicle on a first side of the wheel end assembly, and a second end of the spindle defining a flange and receiving the axle of a vehicle is disclosed. The flange includes a socket joint that receives the axle on the second side of the wheel end assembly. Mounting members extend distally from the second side a first distance to secure the spindle to the wheel end assembly via the flange. The socket joint of the spindle extends from the second side of the wheel end assembly a second distance from the second side. The second distance is greater than the first distance. A third distance represents degree of overlap of the axle by a ratio with respect to the outer diameter of the axle ranging from 8% to 20%.
