An air reservoir for a steering axle is mounted on a trailer, the steering axle comprising a pair of rotation pivoting wheel assemblies. Each wheel assembly has a rotation plate and a steering arm connected thereto. A rod pivotally connects the steering arms, each wheel assembly being rotatably connected to either end of the axle. An air stabilizer assembly is mounted on the axle and is connected to the rod, the air stabilizer assembly having an inflatable damper assembly thereon. An air supply is fluidly connected to an air inlet on the axle, the air inlet being fluidly connected to the damper assembly. The air stabilizer assembly dampens pivotal movement of the wheel assemblies when compressed air from the air reservoir fills the damper assembly. The air stabilizer assembly allows the wheel assemblies to rotate more freely when pressure of the compressed air within the damper assembly is reduced.

A novel hollow shaft manufacturing method includes the steps of hollow cold-rolling of seamless steel pipe, cutting, annealing and surface treatment, forming by forging, precision machining, and heat treatment. The present invention uses a new process instead of the traditional process. The forging process using high-strength cold-rolled seamless steel pipes has fewer steps than using bar stock: saving three forging passes, one annealing pass and one surface treatment pass, hence saving about ½ in time and cost, shortening the cycle, reducing costs, reducing energy consumption and reducing the three wastes, increasing the stock utilization rate to about 68%, and reducing the inter-process cost calculated by weight. For the same products, using this process can shorten the production cycle.

An axle, for a mining machine, includes one or more segments, each defining a first wall portion, a second wall portion disposed opposite to the first wall portion, a third wall portion, and a fourth wall portion. The third wall portion extends between the first and the second wall portions to meet the first wall portion at a first corner portion and the second wall portion at a second corner portion. The fourth wall portion extends between the first and the second wall portions to meet the first wall portion at a third corner portion and the second wall portion at a fourth corner portion. The second thickness of the second corner portion and the third thickness of the third corner portion are greater than each of the first thickness of the first corner portion and the fourth thickness of the fourth corner portion.

Described herein is an axle assembly and method of fabrication thereof. The axle assembly includes an axle having a first geometric shape housed within an axle housing having a second geometric shape. A shock absorber is located between the axle and the axle housing. The shock absorber supports the axle within the axle housing and comprises a first material and comprises a multi-sided configuration. The first geometric shape and the second geometric shape comprising polygons.

An axle system includes an axle stub, a first connecting section and a second connecting section, wherein the axle stub is embodied on its outer side so as to be essentially rotationally symmetrical about a stub axis and has two ducts which extend parallel to the stub axis in certain regions, wherein the connecting sections lie in a connecting plane which is oriented orthogonally with respect to the stub axis, wherein the axle stub has an attachment region for securing a brake carrier which extends parallel to the connecting plane.

An axle assembly includes a central tube and an axle spindle. The axle spindle is fixed to the central tube. The axle spindle has a tubular first section and a tubular second section extending from the first section. The second section has an outer diameter. The second section has a bearing support surface. A tubular transition section is located between the first section and the second section. An annular shoulder portion is formed in an axial end segment of the tubular transition section adjacent the second section. The shoulder portion has at least one annular profile located in the shoulder portion between the annular shoulder surface and the bearing support surface. The annular profile is defined by a surface with a diameter not less than the outer diameter of the second section. An antilock braking system sensor bracket locator nub is integrally formed in the tubular transition section. An antilock braking system sensor bracket engages the antilock braking system sensor bracket locator nub for proper positioning of an antilock braking system sensor.

The present disclosure relates to an axle beam, in particular an axle bridge, for a motor vehicle, preferably a commercial vehicle. The axle beam has a first axle beam shell and a second axle beam shell which is connected, in particular welded, to the first axle beam shell in order to configure a tubular body. The tubular body has an inner circumferential face with a plurality of flat sections which form a non-round cross section of the tubular body. The axle beam has a reinforcing component which has a non-round cross section, is arranged within the tubular body, and bears at least partially against the flat sections of the inner circumferential face of the tubular body.
