  • Publication number: 20130313766
    Abstract: The present invention relates to a method for manufacturing a suspension bearing device, comprising at least one rolling bearing, a bottom cup and a top cup made of plastic, each in contact with the rolling bearing, and at least one seal suitable for protecting the rolling bearing from ingress of water or of polluting particles. The method is characterized in that it comprises at least one step of positioning a seal made of thermosetting elastomer on a supporting element made of plastic between the bottom cup and the top cup and, for the or each seal made of thermosetting elastomer, a step of curing this seal on its supporting element. The invention also relates to a suspension bearing device and a strut of a motor vehicle.

  • Publication number: 20130299303
    Abstract: A vehicle transmission includes a housing part, a shaft extending from the housing part, and a spring element having a plurality of spring windings wound around the shaft, a first end of the spring element being fixed to the housing part. An actuating means is attached to a second end of the spring element and is configured to twist the second end in a circumferential direction of the spring element to thereby cause the spring element to tighten and frictionally contact an outer circumference of the shaft. The spring element is comprised of a hollow cylindrical metal base body having a helical-shaped incision that defines the plurality of spring windings. The incision may be formed in the hollow cylindrical base body by a plasma beam process, by a laser cutting process, by a flame cutting process or by a water jet cutting process.

  • Publication number: 20130277161
    Abstract: The present invention relates to a suspension bearing device, comprising a rolling bearing forming an axial stop along a main axis and at least one seal adapted for protecting the rolling bearing from ingress of water or of polluting particles. The device is characterized in that it also comprises a bottom cup and a top cup made of plastic, in contact with the rolling bearing, the bottom cup forming a bearing means for a suspension spring, and in that the or each seal is made of thermoplastic overmoulded onto a first element between the cups and comprises a base of substantially annular shape from which extends at least one sealing lip in contact with the second element between the cups. The invention also relates to a strut of a motor vehicle, comprising a damper and a suspension bearing device as mentioned above.

  • Publication number: 20130279837
    Abstract: The rolling bearing, in particular for a power steering mechanism, comprises an inner ring, an outer ring, an elastic sleeve in contact axially and radially with one of said rings, and a housing holding the sleeve. The housing provides an axial portion and two lateral flanges extending the axial portion and mounted in contact against the sleeve to exert an axial prestress on said sleeve.

  • Patent number: 8485734
    Abstract: This ball bearing (1) forms an axial force transmission member and comprises an inner ring (3) and an outer ring (4), and a single series of balls (6) placed in a rolling chamber between the inner ring (3) and the outer ring (4). A first ring (4), amongst the inner ring (3) and the outer ring (4), forms a travel track (411) in a section of a sphere centered on a geometric point (C4) belonging to an axis of symmetry (X4) of this first ring (4). The first ring (4) supports a seal (11) insulating the rolling chamber relative to the outside. The second ring (3), amongst the inner ring (3) and the outer ring (4), is provided with a sealing zone (314) designed to interact with the seal and in the shape of a section of a sphere centered on a second geometric point (C3) belonging to an axis of symmetry (X3) of the second ring. The radii (R3, R4) of the sections of a sphere are different.

  • Publication number: 20120039556
    Abstract: The ball bearing (1) forms a member for transmitting an axial force and comprises an inner ring (3), an outer ring (4), balls (6) disposed in a raceway chamber (5) formed between the inner ring and the outer ring, and an annular shield (8) mounted on a radially inner edge face (32) of a first ring (3). The inner and outer rings (3, 4) are mounted with freedom to pivot mutually about a point (C1) common to the axes of symmetry (X3, X4) of the two rings. The shield (8) extends from the first ring (3, 4) to the vicinity of a portion (43) of the second ring (4) that is centered on said common geometric point (C1), and the shield (8) has an end portion (83) with a surface (831) that is a truncated sphere centered on the common geometric point (C1) or a truncated cone centered on the axis of symmetry (X3) of the first ring (3).

  • Publication number: 20120024618
    Abstract: A bearing assembly is for a mechanism including a housing and a rotatable shaft disposed within the housing. The bearing assembly includes a sleeve disposable within the housing and having an inner circumferential surface defining a bore and a radial surface extending radially inwardly from the inner surface. A bearing is disposed within the bore and includes inner and outer races and rolling elements disposed between the races, the inner race being coupleable with the shaft such that the shaft and the inner race rotate as a single unit. Further, a biasing member biases the outer race generally against the sleeve radial surface or a housing radial surface to prevent axial displacement of the outer race during shaft rotation. Preferably, a retainer couples the biasing member with the outer race to retain the bearing and the biasing member within the bore when the assembly is separate from the housing.

  • Publication number: 20110303506
    Abstract: A clutch-release bearing device includes a bearing having a non-rotating ring, a rotating ring with a rolling portion for supporting rolling elements, a contact portion extending from the rolling portion and radially away from the non-rotating ring, and a guide portion extending toward the non-rotating ring and disposed axially against the contact portion to form a fold, and at least one row of rolling elements disposed between the non-rotating and rotating rings. A wear ring is movably mounted on the guide portion of the rotating ring and is configured to contact the clutch mechanism diaphragm. The ring includes a polymeric body and a stiffening insert configured to stiffen the body, the body having a retaining portion disposed generally axially between the rotating ring rolling and contact portions and configured to axially retain the wear ring in relation to the rotating ring.
