摘要:
The invention relates to an adapter for a rolling assembly having an axis of rotation and comprising a tyre that has two beads (B), a rim (J), said adapter providing the connection between one of the beads and the rim, said rim having two rim seats (7), said adapter having an axially inner end (10) intended to be mounted on the seat of the rim (7) and comprising an internal reinforcing element (16), an axially outer end (15) intended to be mounted on the seat of the rim (7) and comprising an external reinforcing element (15), a body (11) connecting said outer end (9) to said inner end (10) so as to form a single unit and comprising at least one main reinforcement providing the connection between said external reinforcement (15) and said internal reinforcement (16), a substantially cylindrical adapter seat (18) being intended to accept one of said beads (B), an adapter bearing face (21) more or less comprised in a plane perpendicular to the axis. This adapter is characterized in that the reinforcing element (15) of the axially outer end (9) is situated entirely axially on the outside of the bearing face (21), and in that the body (11) comprises, facing the adapter seat (7), a seat annular reinforcement (19).

The cover (1) for vehicle tires comprises fixing means (3, 4) which allow said cover (1) to be fixed to a rim (2) of a tire and is characterized in that said fixing means comprise a plurality of protrusions (3), each one of which is associated with a fixing element (4), each fixing element (4) preferably being housed in the interior of one of said protrusions (3). It allows mounting/removal (under pressure) of the plastic covers from the frontal part of the tire facilitating, to a large extent, the personalization of the tire, after the sale of the vehicle, by means of simply interchanging the plastic covers by the end user and/or car dealership.

Selon invention, un tel dispositif comprend des moyens de modification (10, 11, 101, 111) du périmètre du contour extérieur dudit axe (1).
摘要:
The invention relates to a rimless vehicle wheel comprising a hub and a plurality of cantilevered blades spaced around the hub. Each blade has an inner root extending from the hub, an outer tip, and first and second major blade surfaces extending between the root and tip. Each blade has a stiffness allowing independent flexure, along at least part of its length, between a first unloaded blade configuration and any number of second loaded blade configurations. The depth of at least one blade from front to back in the meridian plane measured proximate the blade tip is greater than the same measurement proximate the blade root. The blades are adapted to flex in the circumferential plane of the wheel. Multi-part sleeves are adhered to the blade tips so as to provide a sacrificial wearing surface.
