A telescoping axle arrangement is provided for an agricultural applicator having a frame supported above a ground surface by a ground engaging wheel operatively connected to the frame by the telescoping axle arrangement. A tubular first axle element, and a second axle element slidingly inserted into the first element operatively connect the wheel to the frame, and provide extension and retraction of the axle along a longitudinal axis of the axle. A cylindrical tunnel passing through the first element limits the extent to which the second axle element can be inserted into the first axle element. An inner end of the second axle element is contoured to extend at least partly under the cylindrical tunnel in the second axle element when the second axle element is inserted at a maximum allowed depth into the first axle element.

A wheel support bearing assembly includes a wheel support bearing and a power unit. The power unit is that of an outer rotor design in which a stator is located at an outer periphery of the wheel support bearing and a rotor is located radially outward of the stator. A radial extension of the entire power unit is sized to be radially inward of a peripheral section of a brake rotor. An entirety of the power unit, excluding a mount part thereof to a hub flange, is sized to be situated in an axial range between the hub flange and a mount surface, on an inboard side of the wheel support bearing. The rotor includes an outer shell magnetic body, which is made from soft magnetic material and forms an outer shell of the power unit, and permanent magnets that are provided to the outer shell magnetic body.

An adjustable portal box assembly for selectively mounting a wheel to an off road vehicle in either of two positions. The assembly includes a mounting plate mountable to the suspension of an off road vehicle, and a portal box is mountable to the mounting plate. The portal box includes an input shaft opening for an input shaft, and an output opening for an output shaft. The portal box is mountable to the mounting plate in a first position in which the output shaft is positioned to extend the wheelbase relative to the input shaft, or in a second position in which the output shaft is positioned in vertical alignment with the input shaft.

An auto-leveling drive axle device for a wheel tractor, and leveling method. The device comprises a transmission device and a leveling device. The device of the present invention changes only a vertical position of a drive axle with respect to a wheel, and a wheel shaft distance and wheel center spacing are not changed, thus improving traveling stability of a vehicle.

A portal gear and a method to implement a portal gear for a model vehicle are provided. The portal gear may include a drive shaft attached to an input gear and an axle attached to an output gear. The portal gear may further include a housing to vertically contain the input gear and the output gear. Wherein the drive shaft transfers a rotational torque from an upper location to a lower location via a gear reduction resulting from the input gear rotating the output gear.

A portal hub assembly for raising the chassis of a vehicle. The portal hub assembly includes a portal box and a mounting assembly removably attachable to one side of the portal box. The mounting assembly includes a mounting body forged as a unitary body. A bracket assembly including at least one mounting bracket is selectively attachable to the mounting body to allow the mounting assembly to receive a component of the suspension system of a desired vehicle.

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%.

The twist axle assembly includes a pair of spaced apart trailing arms and a twist beam of which extends in a first direction between the trailing arms. The twist beam includes a pair of end portions and a middle portion. The twist beam further has a pair of side walls and at least one additional wall that extends between the side walls. The side walls in the middle portion are generally parallel with the side walls of the end portions. The twist beam is generally hour-glass shaped with the middle portion having a first width and the end portions have a greater second width. The twist beam also tapers from the first width of the middle portion to the second widths of the end portions for gradually increasing a torsional stiffness from the middle portion to the end portions.

A drive line arrangement for self-propelled agricultural product applicator includes an engine connected to a remotely mounted pump arrangement by a driveshaft that passes through an axle of a frame of the applicator. The axle includes an axle tube extending transversely across the frame and defining front and rear facing surfaces of the axle tube, and a tubular-shaped tunnel fixedly attached to and extending through the axle from the front to the rear facing surfaces of the axle tube, and defining an internal opening of the tunnel for passage of the driveshaft through the tunnel. The tunnel extends beyond at least one of the front and rear facing surfaces of the axle tube to structurally reinforce the axle tube around the opening in the tunnel.

An air disc brake system for a heavy-duty vehicle comprising an axle. A spindle is attached to an end portion of the axle. At least a portion of an air disc brake assembly is supported by the spindle. A suspension beam has an axle support portion connectable with the axle. An end portion of the suspension beam is spaced from the axle support portion for attachment with the heavy-duty vehicle. The suspension beam may pivot about the end portion of the suspension beam. An actuator actuates the air disc brake assembly. The actuator has a movable member to actuate the air disc brake assembly. Structure is associated with the suspension beam for supporting at least a portion of the actuator. A surface defines an opening in the suspension beam through which the movable member may extend or that may receive and support a portion of the actuator.
