Double-axis oscillating bogie wheels

A wheel assembly for mobilizing a construction vehicle upon a base surface, the wheel assembly comprising:

• a connective member movably connected with the vehicle and configured to be pivotable about a first axis and configured to be pivotable about a second axis extending generally perpendicularly with respect to the first axis;
• an axle attached to the connective member so as to be generally freely pivotable about the second axis and having a longitudinal centerline extending generally perpendicularly with respect to the second axis;
• and
• a wheel connected with the axle and configured to rotate generally about the axle centerline such that when the wheel is disposed generally upon the base surface, the wheel rolls with respect to the surface so as to mobilize the vehicle, the wheel being generally vertically displaceable by at least one of angular displacement of the connective member about the first axis and angular displacement of the axle about the second axis while the vehicle traverses the base surface.

A paving vehicle comprising:

• a chassis having a front end, a rear end, first and second opposing sides and a longitudinal centerline extending between the front and rear ends;
• a first wheel assembly connected with the first chassis side and including an axle, the axle having a central portion, two opposing ends and a centerline extending between the two ends, the axle being configured to generally freely pivot about a first horizontal axis extending through the central portion and generally parallel with respect to the chassis centerline, and two wheels each movably connected with a separate end of the axle so as to be rotatable about the axle centerline, each one of the two wheels being vertically displaceable with respect to the other one of the two wheels by angular displacement of the axle about the first axis while the vehicle traverses the base surface;
• and
• a second wheel assembly connected with the second chassis side such that the first and second assemblies are disposed on opposing sides of the chassis centerline, the second wheel assembly including an axle, the axle having a central portion, two opposing ends and a centerline extending between the two ends, the axle being configured to generally freely pivot about a second horizontal axis extending through the central portion and generally parallel with respect to the chassis centerline, and two wheels each movably connected with a separate end of the axle so as to be rotatable about the axle centerline, each one of the two wheels being vertically displaceable with respect to the other one of the two wheels by angular displacement of the axle about the second axis while the vehicle traverses the base surface.

A bogie wheel assembly for a paving vehicle, the wheel assembly comprising:

• a frame movably connected with the vehicle so as to be pivotable about a first axis;
• an axle having a longitudinal centerline and being movably connected with the body so as to be generally freely pivotable about a second axis, the second axis extending generally perpendicularly with respect to the axle centerline and generally perpendicularly with respect to the first pivot axis;
• and
• a bogie wheel movably connected with the axle so as to be rotatable about the axle centerline, the wheel being displaceable generally within a first plane by pivotal displacement of the frame about the first axis and displaceable within a second plane by pivotal displacement of the axle about the second axis, the second plane being generally perpendicular to the first plane, the wheel being displaceable within the second plane while the vehicle traverses a base surface.
