A rim, having a rim body with rim flanks, a rim well and a rim base, in which the flanks abut in the radially most inwardly point, and with opposed rim flanges, each extending from one of the flanks up to a radially most outwardly point, so that the rim flanges form opposed side walls with the flanks. The widest spot of the rim body lies beneath the rim well and above a horizontal centerline. The width in the widest spot is at least one quarter larger than a clear rim width between the rim flanges. The side walls show a defined curvature shape with an inflection point which is disposed between the radially most outwardly point and the widest spot and lies external of the rim flange. In the inflection point, a concave curvature makes a transition to a convex curvature lying between the inflection point and the widest spot.

The invention provides a rim for a braked aircraft wheel, the rim comprising an outer circular portion (103) terminated at its ends by flanges (106a, 106b) for receiving a tire, the outer circular portion being connected by a wheel disk (105) to a hub (104) for fitting on an undercarriage axle in order to rotate about an axis of rotation coinciding with a central axis (X) of the rim, the rim being designed to receive a tire on the outside of the outer circular portion and a brake on the inside, on one side of the wheel disk. According to the invention, the outer circular portion (103a) on the side of the wheel disk that is to receive a brake presents, in a plane containing the central axis of the wheel, a profile that has two slopes ?, ? relative to a direction parallel to the central axis on going from the wheel disk to the corresponding flange, and flaring towards the flange.

Road tubeless rims may include a pair of circumferential flanges having inner tire seating surfaces that are nonconcave and angled toward the centerline. Tubeless tires mounted to the illustrative rims may achieve improved sealing performance due to an increased seating area of the rims. A shape and angle of the flanges may shape the tire to achieve an aerodynamic wheel profile.

A bicycle rim assembly includes a rim defining a central plane and comprising annular inner and outer walls. The outer wall includes first and second bead seats separated by a center well. First and second annular projections are spaced laterally from each other relative to the central plane and extend substantially radially outwardly from the outer wall. Each of the annular projections includes a radially outer face and a laterally inner face. Right and left covers are spaced from each other and are preferably coupled to the rim to cover at least a portion of the laterally inner face and the radially outer face of the first and second annular projections, respectively, and also the first and second bead seats, respectively. One or both of the right and left covers can be fiber reinforced. First and second pieces of tape can be overlapped and used to secure the covers to the rim.

A rim (3) for a tire has an axis of rotation DD and a rim seat (31) extended axially towards the outside by a rim flange (32), said rim flange (32) having a first portion (321) that is oriented substantially in a perpendicular plane and is situated radially on the outside with respect to said rim seat (31), characterized in that said rim flange (32) has a second portion (322) that is inclined towards the outside, is situated axially on the outside with respect to said first portion (321) and is situated at least partially radially on the outside with respect to said rim seat (31), said rim having a connecting portion (320) between said first portion (321) and said second portion (322).

The present invention provides a bicycle rim assembly adapted to be coupled to a hub to create a bicycle wheel. The rim assembly includes a rim and a cover coupled to the rim. The rim defines a central plane and comprises an annular inner wall and an annular outer wall cooperating with the inner wall to define a cavity. The rim further includes annular projections spaced laterally relative to the central plane and extending substantially radially outwardly from the outer annular wall. The cover includes sidewalls disposed on lateral sides of the rim adjacent the projections, each sidewall including a lateral inner portion having a lateral thickness. The cover further includes an annular ring portion interconnecting the sidewalls, the annular ring portion including a radial thickness less than the lateral thickness of the lateral inner portion of the sidewalls. Preferably, the rim comprises a metallic material and the cover comprises a non-metallic material. For example, the rim can comprise aluminum or an epoxy matrix composite, and the cover can comprises a polymeric material, such as ultra-high molecular weight polyethylene. In addition, a radial thickness of the entire cover is preferably substantially less than a radial thickness of the entire rim. In one embodiment, the projections include a laterally inwardly facing surface, a laterally outwardly facing surface, and a radially outwardly facing surface. In this embodiment, the cover engages at least a portion of each of the laterally inwardly facing surface, the laterally outwardly facing surface, and the radially outwardly facing surface. Preferably, each annular projection has a smoothly radiused radially outwardly facing surface, and each laterally outwardly facing surface that lies in a radial plane substantially parallel to the central plane.
