An assembling device including: a bearing setting unit configured to set a bearing unit such that the bearing unit is coaxial with respect to a hub cylindrical part and can be moved toward the hub cylindrical part, a rotational drive source configured to transmit rotational force around an axis to the bearing unit set in the bearing setting unit; and an inner-ring press-fitting unit configured to externally fit a inner rings of the bearing unit to which the rotational force around the axis has been transmitted, to the hub cylindrical part.

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 in 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%.

A wheel assembly includes a first rim piece for engaging a rotatable axle; and a second rim piece for engaging the rotatable axle. The first rim piece has axially extending curved friction plates for engaging a first side of a spoke structure of a tire. Axially outer ends of the friction plates engage axially extending lugs of the second rim piece to form a single split wheel assembly.

An assembly of an outer ring and a knuckle comprises an outer ring used in a wheel bearing and a knuckle for connecting the outer ring to a suspension system. The outer ring comprises a body having a hollow formed in an axial direction of a rotation axis, a mounting portion extending in an outer radial direction and a circumferential direction of the body and having a plurality of first mounting holes formed thereon, and at least one mating protrusion formed on an outer circumferential surface of the body. The knuckle comprises a step portion configured to mate with the mating protrusion in an axial direction of the body. A plurality of second mounting holes corresponding to the plurality of first mounting holes are formed on the knuckle. The mating protrusion has one of a plurality of mating shapes having different shapes.

A front suspension wheel for mobile robotic devices that can be compressed into or decompressed out of a main body of a mobile robotic device to facilitate driving the mobile robotic device over obstacles, thresholds and the like. The wheel will provide the mobile robotic device with information such as how fast the wheel is traveling. The wheel is easily removable by hand by the user.

Wheels adapted to roll on and across surfaces of fields, for example, as part of irrigation systems of types used in agricultural applications. Such a wheel has an axis of rotation, a center portion comprising a central hub concentrically disposed on the axis of the wheel and multiple spokes radiating from the central hub, and a tread portion circumscribing the center portion. A radially outermost extent of each spoke terminates at a spade that is oriented parallel to the axis of the wheel. The tread portion includes tread plates, each located between and attached to adjacent pairs of the spokes. The spades protrude radially outward between and beyond adjacent pairs of the tread plates.

Disclosed is a wheel airtight rubber ring press-fitting device, consisting of a frame, first servo motors, ball screw pairs, first guide rails, a first cylinder and the like. The device may be used for automatic continuous production. The central axis of an airtight rubber ring coincides with the central axis of the outer rim of a wheel, so that the positioning precision is improved, and high-precision press-fitting is realized. Through cyclic switching of double manipulators, the press-fitting feeding time is nested, the press-fitting cycle is shortened, and the working efficiency is improved.

A hub assembly includes a retainer housing, a retaining member, a biasing element, and an occlusion. The retainer housing includes a wheel mounting sleeve and a pin sleeve. The wheel mounting sleeve includes an axle bore configured to receive an axle. The pin sleeve has a first end and a second end. The pin sleeve includes a conduit between the first end and the second end. The first end is in fluid communication with the axle bore. The retaining member and the biasing element are in the conduit. The retaining member is configured to engage a groove in an axle. The biasing element is configured to bias the retaining member towards the axle bore. The occlusion is proximate to the second end of the pin sleeve. The occlusion is configured to inhibit the retaining member from exiting the conduit at least prior to coupling the hub assembly to a wheel.

An apparatus and methods are provided for a bead-locking wheel for mechanically coupling a tire to a wheel rim of an off-road vehicle. The bead-locking wheel includes a barrel for mounting the tire and a bead lock face for fastening the barrel and tire to a wheel hub of the vehicle. The bead lock face is fastened to a shoulder disposed around an outboard end of the barrel. The shoulder and an outboard flange of the barrel cooperate with a periphery of the bead lock face to mechanically retain an outboard bead of the tire. Mechanically retaining the outboard bead facilitates a relatively low inflation pressure within the tire to accommodate off-road conditions and high tractive forces. The bead lock face maximizes a positive offset and backspacing of the bead-locking wheel to accommodate a relatively wide hub and spindle assembly while maintaining an advantageous steering geometry and track width.

A method of making a wheel assembly using hybrid spokes that combines a synthetic fiber cable with an outer rod segment connected to a rim and an inner rod segment connected to a hub. An anchor is used to connect each end of the fiber cable to a length of conventional rod, preferably through the use of a swaging operation. Each rod segment includes a standard end feature on its free endsuch as a threaded shaft or J-bend. The hybrid assembly can preferably be retrofitted to applications that now use a conventional rod or wire. This allows synthetic fiber cableswith their unique mechanical propertiesto be incorporated in existing designs.
