Abstract
An emergency ring of elastic material for a vehicle wheel having a one-piece deep bed rim comprises a one-piece annular support body, which via support rings are supported exclusively on the rim bed of the wheel and is spaced apart from at least one side wall region or of a pneumatic tire. Reinforcement inlays are disposed radially such that there is only relatively little compressible elastic material within the reinforcement inlays. High security against rotation of the emergency ring relative to the rim is thereby assured. Moreover, the emergency ring is easily mounted and provides great security against a tire being thrown off, even when cornering with tires with low air pressure.
Claims18
An emergency ring for a vehicle wheel which is composed of a one-piece rim with a rim bed and a pneumatic tire, comprising a one-piece annular elastic body having annular reinforcement inlays and a radially outside portion on which, in an emergency, a radially inside portion of the pneumatic tire remote from tire tread comes to rest, an axially outer side face, axially an inner side face, and a radially inside portion oriented toward the rim bed,
- wherein the radially inside portion of the emergency ring is supported by at least a part of a surface thereof on the rim bed, and at least one of the axially outer and inner side faces is spaced apart from an adjacent side wall region of the pneumatic tire.
