First Claim
Patent Images
1. A suspension thrust stop drive comprising:
- a cap;
a rolling bearing forming an axial thrust stop, a cup adapted for receipt of a vehicle suspension spring, and an elastic support clock, the rolling bearing being placed between the cup and the elastic support block with said support block being adapted for securement to a vehicle frame, the rolling bearing comprising an upper race placed inside said cap with said cap acting as an interface between said race and the elastic support block in contact with the cap, and a lower race, said cap having means of axially retaining the cup to form a unit assembly, wherein part of the cap covers the periphery of the cup and forms a means of axially retaining the cup relative to the cap, and said cup being made of metal.

Abstract
A suspension thrust-bearing device for a telescopic suspension strut of a motor vehicle which includes a rolling bearing forming an axial thrust stop, a metal cup for accepting a suspension spring, and an elastic support block. The rolling bearing is positioned between the metal cup and the elastic support block which is secured to the frame of the motor vehicle. The rolling bearing includes an upper race placed within a cap which is in contact with the support block, and a lower race. The cap is provided with means for axially retaining the metal cup, to form a unit assembly, and acts as an interface between the upper race and the elastic support block. An outer cylindrical portion of the cap covers the periphery of the metal cup.

15. A suspension thrust stop device for a vehicle, comprising;
-
an elastic support block, adapted for securement to a frame of the vehicle;
a metal cup, adapted for receiving a suspension spring of the motor vehicle; and
a rolling bearing assembly, forming an axial thrust stop, placed between said cup and said elastic support block, said rolling bearing assembly comprising;
a lower race, supported by the metal cup, an upper race, bearings housed between the upper race and the lower race, and said thrust stop device further comprising;
a cap positioned so as to provide an interface between said race and said elastic support block with said cap being in contact with said elastic support block, said cap including an extension covering the periphery of said cup which includes means for axially retaining said cup relative to said cap to form a unit assembly. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34)
providing the bearing assembly in the metal cup; and
capping the bearing assembly with the cap, by snap-fastening the cap on the periphery of the cup with said means of axially retaining and;
wherein no angular orientation of the various components is required for assembly of the thrust bearing device.
