Abstract: A connection assembly for an air maintenance tire system is provided. The air maintenance tire system includes an annular air tube, a valve housing and at least one connecting tube that is in fluid communication with the annular air tube and the valve housing. The connection assembly includes a connection housing that in turn includes a first port, a second port and a fluid passageway extending between the first port and the second port. A first compression fitting fluidly connects the annular air tube to the connection housing first port and a second compression fitting fluidly connects the connecting tube to the connection housing second port. The connection assembly enables a secure connection and fluid communication between the annular air tube and the connecting tube.

Abstract: Taught is an apparatus for converting energy in a wheeled vehicle, comprising a wheel rim; a tire; and a plurality of hydraulic plunger cylinders alternatively distributed on periphery of the wheel rim.
Abstract: A simple method of handling thermomechanical coupling for temperature computation in a rolling tire. First, the sensitivity of the tire elastic response to changes in material stiffness is characterized using the “deformation index”. Then, using a commercial finite element program and an appropriate user subroutine, heat generation is expressed as a function of the local temperature using a simple algebraic expression involving the temperature dependent material properties and the deformation indices. Temperatures are computed using the finite element program with the coupling information contained in the user subroutine. The result is a non-iterative method for a fully-coupled thermomechanical analysis of a tire. The effects of compound changes on tire temperature distribution can also be estimated using the deformation index. The method applies to the energy loss and temperature calculations under both steady-state and transient conditions.
