A spring-force adjustable, height-adjustable industrial caster assembly including a mounting plate, a swivel housing that swivels relative to the mounting plate, and a spring assembly having components that are moveable relative to the swivel housing to controllably alter spring deflection and/or caster wheel height, which components can be adjusted by accessing the height-adjustable industrial caster assembly from above, eliminating the need to raise a pallet truck or other moveable assembly to which the caster assembly is coupled, away from the floor to be able to access and adjust the industrial caster assembly.

An axle assembly that includes a differential carrier, a bearing cap, and a lubricant reservoir. The differential carrier has a bearing support. The bearing cap is disposed on the bearing support. The lubricant reservoir is mounted on the bearing cap and is configured to capture lubricant that is splashed by the differential assembly.

A plug for a hubcap includes a base configured to fit into and obstruct a port of a hubcap. The base at least partially defines a cavity therein. The plug also includes a cap extending radially outward from the base. The cap defines an opening therein, the opening extending at least partially radially, and a passage extending axially between the opening and the cavity. The opening is in fluid communication with the cavity via the passage.

The present disclosure relates to a wheel connecting structure and a baby carrier. The wheel connecting structure includes a fixed base, a rotatable base, a rotating shaft and an anti-swing member. The rotatable base is rotatably connected to the fixed base by the rotating shaft. The anti-swing member has an abutting portion. The anti-swing member is arranged on one of the fixed base and the rotatable base, and the abutting portion abuts against the other of the fixed base and the rotatable base. The abutting portion is provided with a lubricating structure.

Methods and systems are provided for adjusting a lubrication system based on an axle configuration of a tandem axle with a disconnect feature. In one example, a method may include adjusting an oil level in an axle sump of a tandem axle based on an axle configuration of the tandem axle (e.g., whether the tandem axle is operating with one of a 6×4 axle configuration and a 6×2 axle configuration), the axle sump selectably coupled to an external reservoir via a first passage and a second passage, the first passage including an electric pump, the second passage including a valve, and the tandem axle coupled to a drivetrain of a motor vehicle. In this way, an amount of oil in the axle sump may be adjusted based on the tandem axle configuration.

An axle assembly for a working machine is provided. The axle assembly has an axle housing comprising a central portion housing a gear, wherein the gear is configured to rotate about an axis and is configured to be partially disposed in a lubricant reservoir, and at least one arm portion extending from the central portion, with the arm portion housing at least one driveshaft. The axle assembly further includes a conduit assembly configured to direct lubricant from the central portion to the arm portion, with the conduit assembly including a lubricant catcher having an inlet disposed in an interior volume of the central portion.

Systems are provided for an axle arm including a lubricant reservoir and a driveshaft. In one example, system may include a lubricant reservoir of an axle arm comprising a fill line at an edge of a driveshaft, wherein a central axis of the lubricant reservoir is misaligned with a central axis of the driveshaft.

Disclosed are systems and methods for reducing friction on a brake arm of a caster wheel brake. A washer can be positioned between the brake arm and the support arm to reduce friction in this area. Lubricant can also be provided between the brake arm and the support arm, and also between the brake arm and the brake cam, to reduce the friction in these areas. The presently disclosed embodiments therefore allow less force to actuate the brake arm as compared to prior art caster wheels.

A hub-integrated inflation system which functions to convert relative motion at the wheel end (e.g., between the axle and the hub or wheel) into a pumping motion. The relative motion is then converted into mechanical or electrical energy, which can be used to actuate a pump of an inflator.
