Title:
ICE ADAPTIVE TIRE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2014/031692
Kind Code:
A3
Abstract:
An adaptive tire system can include retractable and extendable bolts for enhancing traction, for example, on ice-covered roadways. The system can include pneumatically operated bolt assemblies mounted inside a tire. The bolt assemblies can include locking devices configured to be biased towards a locked position so as to lock deployable bolts into extended and/or retracted positions without the need for persistently or continuously applied actuation force or energy. The system can include wheel-mounted, manually operated controls or remote and/or automated controls. The system can include rotary unions for transmitting actuation controls from a vehicle body into an associated wheel. The bolts can also be adjustable and can include removable and replaceable tips.
