A ground engaging segment providing a running surface for wheels, endless tracks and the like, which is not pneumatic in nature, thereby not susceptible to puncture, and which is resiliently flexible to offer some resistance to shock. The ground engaging segment comprises a base and a number of removable, hollow, tubular ground engaging elements which extend transversely of the direction of travel of the running surface. Said ground engaging elements include an inner face for engagement to the base and an outer face for contact with the ground surface, and angular shaped side faces between the inner and outer faces allowing for resilient flexibility under normal load conditions. It is preferable that the ground engaging elements are open at their ends to allow for dissipation of heat and are arranged in circumferential rows, defining a chevron pattern, to prevent resultant side thrust imposed upon the running surface. In addition, the ground engaging elements are constructed angularly to provide a line about which the side faces can flex, and include a flexible internal reinforcement, built in to the walls of the faces of the ground engaging element to provide reinforcement for the ground engaging element, while maintaining flexibility.

A durable, closed-loop, mobile, multiple-element support system providing cushioning support on an engaged ground surface, said support system comprising: a) a closed loop member mountable for cyclical movement about a support structure, said closed loop member having a support face; and b) a plurality of ground-engaging load-bearing elements secured on said support face, each of said ground-engaging elements comprising: i) an inner element portion bearing on said support face to transmit ground-engaging loads to said support face; ii) an outer element portion with a discrete outer surface for engaging the ground, said outer element portion being positioned in an outward direction away from said inner element portion and in facing spaced relationship to said inner element portion said outer portion having a thickness in the radial direction with respect to said closed loop member; iii) load-bearing deformable side walls in facing spaced relationship to each other and extending from said outer element portion toward said support face, said deformable side walls having a side wall thickness, a height in the radial direction and a width, said sidewall thickness being smaller than the thickness of said outer element portion, said sidewalls deforming under load to support said closed loop member with said outer element in engagement with said engaged ground surface; and iv) a ventilation cavity defined between said side walls, and between said inner element portion and said outer element portion said ventilation cavity having a cavity height in said radial direction, said height being greater than said thickness of said outer portion and having a clear heat-dissipating volume opening to the ambient at a first orifice, said deformable side walls being constructed to reduce said cavity height in response to the application of a normal ground-engaging load on said outer element and resiliently to absorb said normal load while maintaining a clear heat-dissipating volume in said ventilation cavity.
