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.

A bicycle rim comprises a base member, a cover member, and a spoke attachment member. The base member includes a truss structure that defines at least one opening. The cover member at least partly covers the at least one opening of the base member. The spoke attachment member is a separate member from the base member and the cover member. The spoke attachment member is non-rotatably attached to the base member.

An electromotive drive wheel arrangement for a motor vehicle comprises: a stator that is connectable to a wheel carrier in a rotationally fixed manner and that supports a coil-like winding, and a rotor rotatably supported relative to the stator and configured in the form of a wheel rim and arranged at least partially radially outside around the stator, wherein the wheel rim comprises a rim base and a rim star, connected to each other, wherein the rim base includes at least partially a fiber-reinforced plastic, and in the rim base several magnets are integrated in a material connection, and that the rim star includes at least partially a metal material.

An agricultural machine tool includes a wheel body which includes a hub, a rim and at least two arms which each connect the hub and the rim to each other. At least one aperture is provided between the two arms and the rim, and has a closed contour. The tool includes a component which forms an accessory having a profiled portion having a shape which generally corresponds to the closed contour, and a generally superficial portion which terminates the profiled portion. The profiled portion is introduced at one side of the wheel body into the aperture, closing the aperture by form-fitting cooperation. A set of fixing members ensures the retention of the component in a final position, in which the superficial portion moves into a flush state with the arms, at least in the region of the contour.
