Wheel assemblies with non-pneumatic tires

Abstract

A non-pneumatic tire assembly includes a non-pneumatic tire. The non-pneumatic tire includes an inner circumferential ring and an outer circumferential ring defining an annular space and a cylindrical space inside the inner circumferential ring. A plurality of partitions connect the circumferential rings within the annular space. A ground-contacting tread is located on the outer circumferential ring. A rim, including a plurality of pieces, is located within the cylindrical space. The non-pneumatic tire assembly further includes a hub that is removably connected to the rim.

Description

[0001]This application claims the benefit of U.S. Provisional Application No. 62 / 108,112, filed Jan. 27, 2015, the entire disclosure of which is hereby incorporated herein by reference.[0002]BACKGROUND[0003]1. Field of the Disclosure[0004]The present application is directed to a non-pneumatic tire and a wheel assembly using a non-pneumatic tire, and more particularly, to a non-pneumatic tire for outdoor power equipment.[0005]2. Description of Related Art[0006]Many outdoor power equipment devices are provided with pneumatic, or air-filled, tires made of an airtight inner core filled with pressurized gas. A tread, usually reinforced with steel belting or other materials, covers this inner core and provides an area which contacts the traction surface. At times, these tires are damaged or otherwise caused to be deflated during shipment. At other times, these tires may lose pressure after remaining in a single location for extended periods, such as a snow thrower stored in a shed during ...

AI Technical Summary

Benefits of technology

The patent describes a non-pneumatic tire assembly that includes a non-pneumatic tire, a rim, and a hub. The non-pneumatic tire has an inner and an outer circumferential ring with a cylindrical space between them. The tire also has partitions that connect the rings and a ground-contacting tread on the outer ring. This design eliminates the need for air and reduces the risk of punctures. The assembly is designed for use with vehicles and has improved traction and stability.

Problems solved by technology

At times, these tires are damaged or otherwise caused to be deflated during shipment.

At other times, these tires may lose pressure after remaining in a single location for extended periods, such as a snow thrower stored in a shed during summer months.

This can lead to costly warranty issues.

Furthermore, many power equipment users do not set and maintain proper tire pressure.

This may result in improper machine orientation and / or spatial attitude, thereby creating situations which could result in loss of control or stability of the power equipment device.
