A mobile carriage includes a traveling part, a wheel, a bed, a displacement conversion part, and an elastic member. The wheel is provided on the traveling part. The bed is supported by the traveling part to be movable in a traveling direction of the traveling part. The displacement conversion part displaces the wheel relative to the traveling part in accordance with displacement of the bed relative to the traveling part. The elastic member applies a force to return the bed having moved relative to the traveling part to an initial position before the movement. The displacement conversion part displaces the wheel relative to the traveling part in a direction of inertial force acting on the bed.

The suspension further includes a one-piece axle. The axle is disposed through the openings. The axle has a threaded first end engaged with the threaded portion. The axle has an ergonomic grip formed at a second end. The bearing tightly engages an outer surface of the axle in the locked position, thereby rotationally coupling the axle to the dropout.

A low-floor electric axle assembly including: an axle housing, hub motors, planetary gear reducers, hubs, a brake system, C-shaped beams, and a suspension system. Mechanical mounting of the suspension system is compatible with a conventional axle, and arrangement manners of the brake system, the hub motors, and the planetary gear reducers are capable of expanding a width of a coach aisle. Each of the hub motors is arranged coaxially with a rim; a first-stage cylindrical gear drive, bevel gear drive, or hypoid gear drive is removed; an unconventional-structure planetary gear reducer is provided to ensure a high transmission ratio and transmission efficiency; the brake system is arranged at two ends of the axle and at inner sides of the motors, thereby making full use of space at the two ends of the axle, and forming the low-floor electric axle assembly.

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 vehicle wheel axle assembly including: an axle extending along an axial axis having a first end and a second end axially opposed to the first end; a hub shell rotatable about the axle and about the axial axis; a frame element having a dropout for connection with the axle. The axle is a cantilevered axle with a first end removably connected to the dropout. The first end includes an axially outwardly facing first end face. The dropout includes an axially inward facing inboard face and an open slot to receive the axle adjacent the first end, with the open slot including an open entrance portion, a closed terminus region, slot sidewalls extending between the entrance portion and the terminus region. The axle is generally radially inwardly assembled to the open slot through the open entrance.

An axle housing assembly includes an axle housing that includes a center portion and a first arm portion that extends from the center portion. The axle housing assembly further includes a wheel end housing that includes a wheel end body that extends from the first arm portion and a spindle that extends from the wheel end body.

A wheel speed sensing system for a work vehicle having an engine, a transmission, a differential, and an axle, defining a central longitudinal axis and coupled to the differential. The wheel speed sensing system includes a sensor target disposed at the axle and a sensor configured to transmit a sensor signal, wherein the sensor is located adjacently to the sensor target. The sensor target includes a plurality of step splines each having a top surface and first and second planar sidewalls. The sidewalls of the step splines are aligned along a radius extending from the central longitudinal axis, such that the sides are undercut with respect to the top surface. An intersection of each of the sidewalls with the top surface defines an edge forming a relatively sharp transition configured to be sensed by the sensor. A chamfer at the intersection of the sidewalls and the top surface is also contemplated.

A cap is provided for covering the threaded end of a removable spindle, having a cover with thread engaging tabs extending from a reservoir basin. The tabs include surface projections for retaining the cap to the spindle threads. The tabs are formed to fit within available slots of a slotted hex nut connected to the spindle. The cap includes a separately formed skirt or guard to make flexible surface contact with the torsion arm or spindle supporting structure. The skirt can include a sacrificial anode region to provide cathodic protection for the spindle threads and spindle retention nut. The skirt is removable from the cap so that the cap can be reused with a new skirt. The cap is formed to be used with existing spindle assemblies and to be reusable.
