Variable rim system for vehicle tyre - uses control rods to move profile sections between outer and inner positions.

摘要

The wheel rim system improves wheel grip on ice and snow. It has a profile segment (3) and an elastic profile ring (19). The profile segment is moved outwards and inwards by an actuation rod (2), with a gap (21) between the housing and the tyre. Guide rods (4) abut the base plates (20) and the control of the actuation rod is achieved via the antilock braking system controller, and by sensors which give early warning of temp. changes at the road surface. USE/ADVANTAGE - Variable wheel rim system on vehicle adjusts shape of tyre to match prevailing road surface conditions and is esp. useful with ice and snow.
