A rocking arm structure includes an arm body, a motive wheel assembly connected to the arm body, a caster wheel assembly connected to the arm body, and a shaft assembly connected to the arm body and disposed between the motive wheel assembly and the caster wheel assembly. The two wheel assemblies are configured to revolve in a same direction around the shaft assembly and for example allow a 4-wheeled vehicle/robot to become a 6-wheeled vehicle for stability as required during changes of terrain.

Axle seat assemblies and methods of manufacturing thereof, are provided for attachment to an axle body (15). The axle seat assembly may be comprised of a first piece (42) and a second piece (50). The first piece (42) may have a first wall, a second wall and a first axle seat piece engagement portion providing a first engagement surface. The second piece (50) may have a third wall and a second axle seat piece engagement portion providing a second engagement surface. The first wall and the second wall of the first piece are oriented to engage a front surface of an axle body and the third wall of the second piece is oriented to engage a rear surface (30) of an axle body. The first and second engagement surfaces of the respective first and second pieces of the axle seat assembly are positioned and configured to engage one another to removably and reversibly secure with the use of a fastener the first piece to the second piece to form an axle seat assembly.

A vehicle suspension is provided, including an axle having an axle body with an exterior surface, a main trailing arm shell portion having a first axle engagement surface configured for engaging a first portion of the exterior surface, and a second trailing arm shell portion having a second axle engagement surface configured for engaging a second portion of the exterior surface. Upon assembly to the axle, the main trailing arm shell portion and the second trailing arm shell portion engage more than 180° of a curvature of the exterior surface.

A method for determining an axle load and a suspension system are configured for a vehicle having at least one leaf spring connected at its ends in spring holders of a vehicle body and connected in its central region to a chassis of the vehicle. The following steps are performed: measuring a measurement distance of the vehicle body relative to the chassis; determining whether there is currently a loading or unloading process of the vehicle, determining a relevant hysteresis curve of a pre-stored hysteresis field depending on the determination of a loading or unloading process, and determining a current axle load projection value from the measurement distance and the relevant hysteresis curve. A loading process criterion and an unloading process criterion may be considered. The determined axle load projection value thus serves as a projected or estimated axle load. Furthermore, the hysteresis field can be updated.

A safety strap apparatus for use with a vehicle's super single tire to protect a rim of the tire from damage during a tire blowout is provided. The super single tire and rim are coupled to an axle mechanically coupled to a frame of the vehicle by a shock absorber. The safety strap apparatus includes a strap assembly having a first elongated strap coupled to a second elongated strap, the strap assembly having a left end portion having an overlapped portion with end portions of the first and second elongated straps and a right end portion including another end portion of the first elongated strap, the left and right end portions being coupled together to create a loop. The loop is disposed around top and bottom portions of the shock absorber. Tension in the strap assembly supports the rim above the ground during the tire blowout.

An axle tie rod adapted to be secured to an axle tube of a utility vehicle includes a connecting element and at least one link element, wherein the connecting element has a first connecting section in which a welded connection with the link element can be produced, wherein the connecting element has a second connecting section in which a welded connection with an axle tube can be produced, and wherein the second connecting section is configured to engage around the axle tube.

An axle arrangement for a baler having a chassis includes a first axle having opposite ends and a pair of suspension cylinders, with each suspension cylinder positioned at a corresponding end of the first axle to accommodate generally vertical loads. The first axle is coupled with the chassis to accommodate generally horizontal loads. A second axle has opposite ends and a pair of suspension cylinders, with each suspension cylinder positioned at a corresponding end of the second axle to accommodate generally vertical loads. The second axle is coupled with the first axle to accommodate generally horizontal loads.

A vehicle rigid axle with an axle beam, at the ends of which axle journals or wheel carriers, are arranged, and trailing arms rigidly attached with a spring bracket for supporting an air-suspension bellow, and a method for manufacturing the vehicle rigid axle. An axle beam section extending between the trailing arms, a trailing arm adjoining the axle beam section and the spring bracket are formed by two shell elements connected to each other, which form a hollow body. In an embodiment, the spring bracket is formed by a lower shell element forming an axle beam section extending between the two trailing arms, and the spring bracket is arranged so that the air-suspension bellow mounted on the spring bracket is penetrated by the central longitudinal axis of the axle beam section. Two shell elements made of sheet metal are formed and joined together to form a hollow body.

A spindle sleeve and washer for adjusting the camber, toe, or thrust angle of a vehicle wheel to a desired predetermined angle which allows for use of existing hub and spindle assembly without permanent modification to the vehicle.

A damping air spring and shock absorber combination for heavy-duty vehicle axle/suspension systems includes a damping air spring and a shock absorber both operatively attached to the axle/suspension system. The damping air spring primarily provides damping to the axle/suspension system over a first range of frequencies. The shock absorber primarily provides damping to the axle/suspension system over a second range of frequencies. The first range of frequencies is from about 0.0 Hz to about 6.0 Hz and the second range of frequencies is from about 0.0 Hz to about 13.0 Hz.
