It is disclosed a system for leveling of load between front and rear wheels on a trailer, consisting of a rubber-torsion axle FIG. D with longitudinal members 4 which center is pivotally mounted to the torsion axles pivot arms 7. With a wheel in each end of the longitudinal members, the system is working as a complete bogie unit which has vertical spring motion effect, as shown in FIG. B. For trailers with no need of such spring motion effect, the longitudinal members can be mounted direct to the inner tube 9 in the rubber-torsion element.

Provided is a running device including a frame (11) and a first wheel part (15) and a second wheel part (35) arranged with an appropriate distance therebetween along a running direction (R). The first wheel part (15) includes a first left support arm (17) and a first right support arm (26) arranged on the frame (11) in a manner to be swingable within a plane extending along the running direction (R). The second wheel part (35) includes a second support arm (36) arranged on the frame (11) in a manner to be swingable within a plane perpendicular to the running direction (R). The first left support arm (17) has first left wheels (19, 21) respectively on both sides thereof, and the first right support arm (26) has first right wheels (28, 30) respectively on both sides thereof. The second support arm (36) has a second left wheel (38) and a second right wheel (40) respectively on both sides thereof.

An elastomeric bearing includes an inner member that has a spherical exterior surface and is symmetric about a central axis and a hollow annular outer structure that is axially split thereby forming a first outer segment and a second outer segment. The first outer segment and second outer segment form a substantially cylindrical exterior surface. One or more shim structures are formed around the inner member and are disposed at least partially inside the hollow annular outer structure. The shim structure has a radially outward facing surface and a radially inward facing surface. One or more layers of elastomeric material are disposed on each of the radially outward facing surface and the radially inward facing surface.

A skid-steer delivery autonomous ground vehicle has a drive train and suspension that aids in maneuverability. The AGV has six wheels, each of which is powered by its own motor. The AGV has features that diminish the dragging effect on the wheels, either by choice of wheel features or by taking weight off the front wheels during turning.

A bogie positioning system and method for a work machine. The bogie positioning system adapted to selectively engage a wheel of a work machine to a ground surface through a bogie assembly wherein the bogie assembly may have a front wheel coupled to a rear wheel through a bogie coupling mechanism. The bogie coupling mechanism comprising a beam with a rotary joint. The rotary joint allowing the front wheel to rotate about a rotary axis relative to the rear wheel. The beam is coupled to a chassis of the work machine with at least one actuator coupled to the beam. A control unit is in communication with the bogie assembly, a user input interface, and a plurality of sensors, generating command signals to actuate the actuator based on the input signals, thereby selectively engaging the front wheel or the rear wheel with the ground surface.
