Definitions

  • the invention relates to the field of suspension thrust bearing devices used in particular on motor vehicles in the telescopic MacPherson struts of the steered wheels .
  • the suspension thrust bearing device is usually p laced in the top portion o f the MacPherson strut between a suspension spring and a supporting blo ck secured to the body shell o f the vehicle .
  • the suspension spring is placed around the rod of a damper piston the end of which, usually the end of the piston rod, is secured to the supporting block.
  • the suspension thrust bearing device thus makes it possible to transmit axial forces between the spring and the body shell o f the vehicle while allowing a relative angular movement between a bearing mount of the spring, that is able to rotate, and the supporting blo ck that is fixed and secured to the body shell o f the vehicle .
  • This relative angular movement can arise from a steering o f the steered wheel and/or from the compression o f the suspension spring.
  • Certain suspension thrust bearing devices are fitted with shock- absorbing pads surrounding the rod of the damper cylinder and designed to be compressed between the body o f the cylinder and the device when there are extreme travels of the suspension. This prevents the damper rod from bottoming in the cylinder.
  • Document GB 2 347 906 describes a suspension thrust bearing device comprising a bottom cover made of plastic having a radial extension extending towards the inside of the suspension spring and serving as a bearing surface for the shock-absorbing pad. Such a bottom cover lacks rigidity during impacts generated by extreme travels o f the suspension.
  • Document FR 2 857 906 describes suspension thrust bearing device comprising a rolling bearing mounted on a bottom cover.
  • the bottom cover described comprises a body made of synthetic material and a reinforcing metal insert covered by said cover.
  • the metal insert gives the bottom cover a good mechanical strength to the axial forces generated by the compression o f the shock-absorbing pad.
  • the metal insert is embedded into the body made of synthetic material. This makes it possible to use a raw steel insert and prevents having recourse to corrosion-prevention treatments of the insert.
  • the bottom cover described comprises an annular rib used for centring the spring and separating the bearing surfaces of the spring and of the shock-absorbing pad. When there are impacts generated by the extreme travels of the suspension, the shock-absorbing pad is compressed axially and extends radially. It is noted however that the annular rib can be damaged by the radial expansion of the shock-absorbing pad.
  • Document FR 2 899 154 also describes a suspension thrust bearing device o f a vehicle fitted with a shock-absorbing pad.
  • the device comprises a bottom cover placed between the spring and the shock-absorbing pad on one side and the bearing of the device on the other.
  • a metal cup is interposed between the bottom cover and the shock-absorbing pad.
  • the metal cup is used for the radial confinement of the shock-absorbing pad.
  • This cup is an additional part making assembly o f the suspension more complex.
  • the metal cup must be treated against corrosion.
  • the cup described has a bore for the passage of the damper rod.
  • the invention proposes a suspension thrust bearing device designed to accommodate a shock-absorbing pad and a telescopic strut which remedy the aforementioned drawbacks.
  • One obj ect of the invention is to propose a suspension thrust bearing device with improved mechanical strength to the forces generated axially and radially by the shock-absorbing pad and to do so without making assembly o f the device more complex.
  • the suspension thrust bearing device comprises a bottom cover having a bearing surface capable o f accommo dating a suspension spring and a rolling bearing in contact with the bottom cover.
  • the bottom cover comprises a reinforcing framework, which framework has a bearing collar extending radially relative to the axis o f the rolling bearing and placed axially between the rolling bearing and the bearing surface of the spring in order to reinforce the mechanical strength o f the bottom cover to the axial lo ads originating from the forces exerted by the suspension spring.
  • the framework comprises an inner radial extension and an axial portion extending in a direction away from the ro lling bearing in axial protrusion relative to the inner radial extension and while being situated radially outside the radial extension so as to be able to accommo date a shock-absorbing pad.
  • the inner radial extension and the axial portion are respectively capable of reinforcing the mechanical strength o f the bottom cover to the axial and radial forces originating from said shock-absorbing pad.
  • the framework helps to mechanically stiffen the bottom cover against the axial forces exerted on the inner radial extension, notably by the shock-absorbing pad.
  • the axial portion of the framework of the bottom cover improves the mechanical strength to the forces generated radially, notably by the shock-absorbing pad compressed when there are extreme travels of the suspension. Since the axial portion forms part of the framework of the bottom cover, there is no additional part relative to the framework portion axially stiffening the bottom cover.
  • the assembling o f the bottom cover or of the suspension is therefore particularly simple.
  • the bearing collar prevents the bottom cover from breaking apart radially.
  • the bearing collar and the inner radial extension are substantially parallel and connected together by a connection portion, the radial extension being o ffset axially relative to the bearing co llar on the side away from the ro lling bearing. This makes it possible to reinforce the axial resistance of the bottom cover.
  • connection portion is frustoconical, or partially toroidal with a centre of curvature of the torus situated on the side o f the spring. This means that the suspension spring is better centred relative to the rolling bearing o f the rolling-bearing device.
  • the axial portion protrudes axially from the connection portion.
  • the inner radial extension consists of a plurality of angular sectors.
  • the axial portion consists of a plurality o f lugs placed angularly in alternation with the angular sectors of the radial extension.
  • the framework is made of pressed metal sheet, which makes it possible to obtain a low-cost framework.
  • the bearing collar has a plurality o f through- ho les participating in the attachment of the framework relative to the bottom cover.
  • the bottom cover comprises a body made o f synthetic material overmoulded all round the framework. This makes it possible to avoid treating the metal framework o f the cover against corrosion.
  • the body made of synthetic material prevents any direct contact between the shock-absorbing pad and the edges o f the framework. This also makes it possible to have a cover without sharp outer edges in contact with the shock-absorbing pad, which prevents reducing the service life of the shock-absorbing pad.
  • the body has a continuous annular portion coating the axial portion of the framework.
  • the annular portion reinforced by the axial portion o f the framework, radially confines the shock-absorbing pad which makes it possible to increase the axial stiffness of the shock-absorbing pad after the beginning of the squashing.
  • the body o f the bottom cover comprises a retaining rim protruding from the annular portion in an inner radial direction.
  • the rim is situated at an axial distance from the inner extension, thus axially retaining the shock-absorbing pad.
  • a bellows for protecting the damper cylinder may be attached to the shock- absorbing pad by means of this rim, which simplifies the suspension thrust bearing device.
  • the invention also relates to a telescopic strut comprising a suspension thrust bearing device as described above, a suspension cylinder and a suspension spring coaxial with the rolling bearing and also comprising a shock-absorbing pad one end o f which can rest against the bottom cover in the zone o f the inner radial extension o f the framework while being surrounded by the axial portion o f the framework.
  • Figure 1 is a view in axial section o f a suspension thrust bearing device according to the invention, the section being made along I-I of Figure 2;
  • Figure 2 is a first view in perspective of the metal framework provided in the bottom cover of the device o f Figure 1 ;
  • Figure 3 is another view in perspective o f the same metal framework.
  • the suspension thrust bearing device referenced 1 in its entirety in Figure 1 comprises a rolling bearing 2 mounted between a top cover 3 having reinforcing ribs 3 a on its bore and a bottom cover 4 having reinforcing ribs 4a o f substantially triangular section in the vicinity o f its bore .
  • the device 1 is incorporated into a telescopic MacPherson strut comprising a suspension spring 5 the top turn of which rests on the bottom cover 4 and a suspension cylinder comprising a rod 6 with an axis 6a that is assumed to be vertical.
  • a shock-absorbing pad 7 made o f a flexible material such as a rubber or similar material is mounted on the top portion of the rod 6 inside the turns of the spring 5 and interacts with the bottom cover 4 as will be explained in detail below.
  • the suspension thrust bearing device 1 is connected by means o f the top cover 3 to the body shell o f the vehicle not shown in the figure.
  • the bottom cover 4, with its axis 6a, comprises a body made o f synthetic material overmoulded round a reinforcing framework 8 the structure of which can be seen more particularly in Figures 2 and 3 and which is, in the example illustrated, made of pressed metal sheet.
  • the ro lling bearing 2 is, in the examp le illustrated, a ball bearing. It comprises a top ring 9 made o f pressed metal sheet, a bottom ring 10 also made of pressed metal sheet and a row of balls 1 1 .
  • the ro lling elements formed by the balls 1 1 are placed between raceways formed by the top ring 9 and bottom ring 10, which can be obtained from one and the same metal sheet blank by cutting and pressing by virtue of the fact that the outer diameter of the top ring 9 is substantially equal to the inner diameter of the bottom ring 10.
  • the top ring 9 is in contact via a toroidal surface with the top cover 3 which the top ring 9 matches in shape.
  • the bottom ring 10 also has a toroidal portion the top surface of which forms the raceway for the balls 1 1 and which comes into contact externally with a corresponding toroidal surface of an annular rim 12 o f the bottom cover 4.
  • the top cover 3 with its axis 6, has an outer axial skirt 13 and an inner axial skirt 14.
  • the rolling bearing 2 is comp letely housed between the two skirts 13 and 14.
  • the outer skirt 13 leaves a free space between it and the annular rim 12 of the bottom cover, thus forming a seal o f the labyrinth type for the ro lling bearing 2.
  • the axial skirt 14 has a plurality of hooks 15 directed radially outwards which can interact with the corresponding hooks 1 6 directed radially inwards and forming part of the bottom cover 4. In this manner, the bottom cover 4, the top cover 3 and the ro lling bearing 2 can form a single assembly making it easier to store and handle the suspension thrust bearing device 1 before it is mounted. In operation, a free space is retained between the respective hooks 15 and 16, thus forming a labyrinth seal to seal the rolling bearing 2.
  • the reinforcing framework 8 that can be seen in Figures 1 to 3 , is fully embedded into the bottom cover 4 and has an annular outer bearing co llar 17 extending radially relative to the axis 6a o f the rolling bearing 2 which is also the axis o f the reinforcing framework 8.
  • the bearing collar 17 is placed axially between the rolling bearing 2 and the top turn of the spring 5 which rests on the bottom cover 4 via a toroidal surface 1 8 o f said cover 4.
  • the bearing collar 17 makes it possible to increase the mechanical resistance of the bottom cover 4 to the axial lo ads originating from the forces exerted by the suspension spring 5.
  • the reinforcing framework 8 also comprises an inner radial extension 19 which consists, as can be seen notably in Figure 2, o f three angular sectors 19a, 1 9b and 1 9c distributed evenly, leaving a circular passageway 26 in their centre .
  • the inner radial extension 1 9 is offset radially inwards and axially downwards relative to the outer bearing co llar 17.
  • the angular sectors 19a to 19c are identical to one another and in this instance extend in the circumferential direction over an angular sector of approximately 1 00° .
  • the angular sectors 19a to 19c extend radially inwards.
  • the reinforcing framework 8 also comprises an axial portion 20 consisting o f three lugs 20a, 20b and 20c placed angularly in alternation with the angular sectors 19a, 19b, 19c and extending axially on the side away from the bearing collar 1 7 and from the rolling bearing 2, i. e. axially downwards .
  • the axial portion 20 is offset radially outwards relative to the inner radial extension 19 and radially inwards relative to the outer bearing collar 17.
  • the reinforcing framework 8 is obtained at least cost from a thin metal sheet blank by pressing, the lugs 20a, 20b, 20c being obtained by cutting the inner radial extension 19 and bending the cut elements thus obtained to the axial position that can be seen in the figures .
  • the result of this is that the lugs 20a, 20b, 20c have a trapezoidal shape as can be seen in Figures 2 and 3.
  • the number of these lugs can be modified as can the number of the sectors 19a, 19b, 19c which form the radial extension 19.
  • the reinforcing framework 8 could also be obtained by machining. In this case, it is possible to provide, for the inner radial extension 19 and for the axial portion 20, a generally annular shape.
  • connection portion 21 The outer bearing co llar 17 and the inner radial extension 19 o f the reinforcing framework 8 are substantially parallel and are connected together by an annular connection portion 21 .
  • the axial portion 20 extends axially downwards the bottom end o f the connection portion 21 , the inner radial portion 19 radially extending said end inwards.
  • the connection portion 2 1 is o f toroidal shape, the centre of curvature of the torus being situated towards the outside, that is to say on the side of the spring 5.
  • the connection portion 21 could be frustoconical.
  • each o f the ho les 22 is made in a portion of the bearing co llar 1 7 which is radially in the continuity o f one of the sectors 19a, 1 9b or 19c.
  • These ho les 22 make it possible to improve the coupling of the synthetic material forming the body o f the bottom cover 4, a synthetic material which is overmoulded onto the reinforcing framework 8. Specifically, during the overmoulding operation, the synthetic material which surrounds the whole of the reinforcing framework 8 penetrates the through-ho les 22 as can be seen in Figure 1 .
  • the reinforcing framework 8 is thus completely embedded into the synthetic material forming the body of the bottom cover 4.
  • the axial lo ads originating from the forces o f the suspension spring 5 are absorbed by the bearing collar 17 while the radial loads originating from the spring 5 are absorbed by the connection portion 21 .
  • the body of the bottom cover 4 has, at its bottom end, a continuous annular portion 23 extending axially downwards and into which the lugs 20a, 20b, 20c which form the axial portion 20 o f the reinforcing framework 8 are sunk or embedded.
  • This annular portion 23 axially fo llows a radial portion 23 a inside which the sectors 19a, 19b and 19c are embedded and which has a bore 23b for the rod 6 to pass through.
  • the annular portion 23 comprises, in its bottom portion, a retaining rim 24 which protrudes radially inwards and which is axially at a distance from the inner extension 19 of the reinforcing framework 8.
  • This retaining ring 24 can interact with a protruding circular rib 25 provided on the shock-absorbing pad 7.
  • the interaction of this rib 25 with the retaining rim 24 makes it possible to provide the axial ho ld o f the shock-absorbing pad 7 relative to the suspension thrust bearing device 1 .
  • the top end of the shock-absorbing pad 7 is housed in the annular portion 23 o f the bottom cover 4, an axial space remaining between this top end and the radial portion 23 a.
  • 19a, 1 9b, 19c makes it possible to absorb the axial forces which may be exerted by the shock-absorbing pad 7 on the radial portion 23 a o f the bottom cover 4 during the compression impacts generated by extreme travels of the suspension. Specifically, during such travels, the shock-absorbing pad 7 is compressed axially against the radial portion 23 a o f the bottom cover 4, which also causes it to squash or expand radially outwards in the direction of the continuous annular portion 23.
  • the axial portion 20 o f the reinforcing framework 8 formed by the three lugs 20a, 20b , 20c makes it possible, for its part, to absorb the radial forces generated by the squashing of the shock- absorbing pad 7.
  • the continuous annular portion 23 reinforced by the axial portion 20 o f the reinforcing framework 8 radially confines the shock-absorbing pad 7, which makes it possible to increase the axial stiffness of said shock-absorbing pad after it has begun to squash.
  • the reinforcing framework 8 By virtue of the structure of the reinforcing framework 8 , all o f the axial and radial forces are absorbed which are exerted on the suspension thrust bearing device, at the same time by the suspension spring 5 and by the shock-absorbing pad 7, notably when there are compression impacts applied to the suspension. Moreover, the production of the bottom cover by overmoulding round a metal reinforcing framework makes it possible to prevent any risk of damage to the shock-absorbing pad during the extreme travels of the suspension, since the shock-absorbing pad comes into contact in this case with the synthetic material of the bottom cover 4 and no longer with the rigid material o f the reinforcing framework.
