Abstract:
Vehicle wheel, with symmetry of revolution, including a disc and a rim, the rim including a first and a second seat which seats are designed to receive and to hold a first and a second bead of the tire, each seat having a substantially frustoconical bottom locally coinciding with a cone of revolution coaxial with the rim and open towards the other seat, a safety hump extending the bottom of the seat towards the other seat, and an external lip extending the bottom of the seat in the direction away from the other seat, the maximum diameter of the first seat being less than the maximum diameter of the second seat, characterized in that each seat includes, on the side facing the other seat, an adjacent circumferential groove and in that the connecting region where the disc and the rim meet is connected to the said rim on the second seat side.
Abstract:
A vehicle rim, of revolution, intended for mounting a tire and an annular bearing support capable of supporting a tread of the tire in the event of a loss of inflation pressure from the tire. This rim includes a first and a second rim seat, each intended to receive a bead of the tire. Each of the rim seats has a generatrix the axially inner end of which is on a circle of diameter DI greater than the diameter DE of the circle on which the axially outer end is located. The first rim seat is delimited axially to the inside by a protrusion, the external diameter DS of which is greater than the mean diameter DP of a supporting bearing surface of the rim. The supporting bearing surface is formed of at least one substantially cylindrical surface of revolution of mean diameter DP extending axially between the two seats and intended to be in close contact with the bearing support. A circumferential groove is located axially between the supporting bearing surface and the first rim seat, the axial width LG of the groove being adapted to permit the support to pass over the protrusion.
Abstract:
A vehicle rim with symmetry of revolution intended for mounting a tire, including a first seat intended to receive and retain a first bead of the tire; a mounting groove; and a second seat intended to receive and retain a second bead of the tire, the second seat being of an average diameter smaller than the average diameter of the first seat, characterized in that the maximum radial depth of the mounting groove (Hmax) is such that the second bead can negotiate the first seat.
Abstract:
The object of the invention is a rotationally symmetric vehicle wheel rim (26) designed for the mounting of a tyre, comprising a first seat (30) intended to be positioned towards the inside of the vehicle and a second seat (32), the first seat (30) being extended axially towards the second seat (32) by a safety hump (40) and comprising a frustoconical bottom (34) which coincides locally with a cone of revolution (46) open towards the second seat (32) and coaxial with the rim (26), and an inner edge (36) which extends the bottom of the first seat (30) towards the second seat (32), such that on the hump side the inner edge (36) of the first seat (30) is tangential to a cone of revolution (48) coaxial with the rim (26) and open towards the second seat (32, with an apex angle larger than 103°.
