First Claim
1. A track assembly for a vehicle, the track assembly comprising:
- a track comprising a ground-engaging outer surface, an inner surface opposite to the ground-engaging outer surface, a first lateral edge, and a second lateral edge, the track including flexible material extending to the ground-engaging outer surface, the inner surface, the first lateral edge, and the second lateral edge, the track comprising a wheel-contacting projection that projects from the inner surface and comprises part of the flexible material; and
a plurality of track-contacting wheels to guide the track around the track-contacting wheels, the flexible material of the track flexing around the track-contacting wheels, the track-contacting wheels including;
a leading wheel and a trailing wheel spaced from one another in a longitudinal direction of the track assembly; and
a plurality of support wheels for rolling on a lower run of the track and disposed between the leading wheel and the trailing wheel in the longitudinal direction of the track assembly, wherein;
each support wheel is pivotable about a pivot axis transversal to a widthwise direction of the track assembly;
a first one of the support wheels and a second one of the support wheels are spaced from one another in the longitudinal direction of the track assembly and pivotable relative to one another about the pivot axis; and
respective ones of the support wheels are spaced apart in the widthwise direction of the track by a space configured to receive the wheel-contacting projection of the track.

Abstract
A vehicle wheel assembly is provided which includes a vehicle frame having a first axle, a wheel assembly having a housing with an aperture engaging the first axle and enabling the wheel assembly to pivot in a first plane about a first axis formed by the first axle. A cylindrical member is carried by the housing of the wheel assembly, the cylindrical member and housing are arranged perpendicular to the first axle. A first wheel is pivotably connected to a first portion of the cylindrical member and a second wheel is pivotably connected to a second portion of the cylindrical member. The first wheel and second wheel independently pivot in a second plane about a second axis formed by the cylindrical member. The first axis is arranged perpendicular to the second axis and the first plane is arranged perpendicular to the second plane.
