Abstract
An apparatus is provided that has a hub through which a central axis extends in an axial direction, and a support structure located outward from the hub in a radial direction. A shear band is located outward from the support structure in the radial direction, and has a matrix and a plurality of weight reduction elements in the matrix that extend in the axial direction. Each one of the weight reduction elements defines a void and is made of a material composition different than that of the matrix. A tread is located outward from the shear band in the radial direction and is configured for engagement with a road surface.
Claims15
A non-pneumatic tire, comprising:
- a hub through which a central axis extends in an axial direction;
- a support structure that is located outward from the hub in a radial direction;
- a shear band located outward from the support structure in the radial direction, wherein the shear band has a matrix and a plurality of weight reduction elements in the matrix that extend in the axial direction, wherein each one of the weight reduction elements defines a void and is made of a material composition different than that of the matrix, wherein at least some of the weight reduction elements form at least one layer in that the weight reduction elements of the layer are all located the same distance from the central axis in the radial direction and engage immediately successive ones of the weight reduction elements of the layer;
- and
- a tread located outward from the shear band in the radial direction and configured for engagement with a road surface;
- wherein some of the weight reduction elements are located in the layer that is a first layer that is an inner layer of the weight reduction elements in the radial direction, and wherein some of the weight reduction elements are located in a second layer that is an outer layer of the weight reduction elements in the radial direction, wherein the second layer is located farther from the central axis in the radial direction than the first layer is located from the central axis in the radial direction.
