Thrust bearing and suspension for vehicle

A suspension thrust bearing device comprising:

• a bottom cover capable of receiving a bearing surface of a suspension spring and a rolling bearing, and directly contacting a shock-absorbing pad such that the bottom cover limits axial movement of the shock-absorbing pad in both axial directions, the bottom cover comprising a reinforcing framework provided with a bearing collar extending radially relative to the axis of the rolling bearing and placed axially between the rolling bearing and the bearing surface of the suspension spring in order to reinforce the mechanical strength of the bottom cover to the axial loads originating from the forces exerted by the suspension spring, the bearing collar being annular in shape, the reinforcing framework further provided with an inner radial extension, and wherein
• the reinforcing framework comprises an axial portion extending in a direction away from the rolling bearing in axial protrusion relative to the inner radial extension while being situated radially outside the inner radial extension so as to be able to accommodate the shock-absorbing pad, the inner radial extension and the axial portion being respectively capable of reinforcing the mechanical strength of the bottom cover to the axial and radial forces originating from said shock-absorbing pad,
• the reinforcing framework further comprises a connection portion adapted to directly connect the bearing collar to the axial portion and the inner radial extension.
