Definitions
- the invention relates to a steering rear axle of a motor vehicle.
- the invention more particularly relates to a rear axle director of a motor vehicle, comprising two longitudinal oscillating drag arms whose first ends are each hinged relative to a body structure element of the vehicle, of which intermediate parts are connected to each other. other by a cross-member, and whose second ends each receive a wheel support in rotation with a substantially vertical axis, the wheel supports being each connected to first ends of connecting rods whose second ends are connected to a first end of a pivoting beam whose second end is driven by an actuator.
- the spreader is pivotally mounted substantially in the middle of the crossbar, for reasons of purity of the axle.
- the second end of the lifter is connected via a rod to the actuator which is attached to the body structure member.
- This design consisting of a set consisting of a cross member, an anti-roll bar and various reinforcement, is a high cost.
- the cross is made from a stamped sheet, and it comprises in the central part specific stampings for fixing a central pivot of the spreader, and punching allowing the passage of screws ensuring the maintenance of the central pivot.
- This design therefore involves stamping and punching operations of the cross member which increases the cost.
- the invention provides a solution for the implementation of a steering system on a rear axle with a tubular cross member, whereas the state of the art described by the document FR-2 862 937 allows an implantation only on a cross-member in pressed sheet metal. .
- the invention overcomes this disadvantage by providing a support means of the rudder and the actuator that can be grafted onto a bare beam.
- the invention provides an axle of the type described above, characterized in that the spreader and the actuator are carried by a housing which is attached to the cross axle and which is mechanically decoupled from said cross.
- the housing has a first end which is fixed to one of the arms of the axle, a tubular intermediate portion which is arranged without contact around the cross member, and a second tubular end which receives internally a resilient element interposed between the housing and the associated part of the crossing,
- the elastic element comprises an elastic shim made of elastomeric material which is arranged around the sleeper in the second tubular end of the casing,
- the intermediate portion of the casing receives at least one anchor point of the actuator and the second end externally receives a pivot of the pivoting beam
- first and second shells each have substantially the shape of a gutter of transverse orientation and each shell has at each of its longitudinal ends a wing intended to be fixed on a wing opposite the complementary hull,
- each shell associated with the first transverse end of the casing, comprises at least one attachment means to a plate fixed rigidly to one of the arms of the axle,
- each shell has an L-shaped section, the two shells having a U-shaped section intended to receive a branch of the plate between its opposite branches, and contiguous branches of the first ends of each shell each comprise a bore, forming the fastening means, which is to be traversed by a fixing screw which is received in a prison nut secured to the plate,
- FIG. 1 is an overall perspective view of an axle according to a prior art
- FIG. 2 is a perspective view of an axle according to the invention
- FIG. 3 is a detailed perspective view of the housing
- FIG. 4 is a sectional view of the cross member by a plane passing through the axis of the rudder.
- FIG. 1 a steering rear axle 10 made according to a prior art.
- the rear axle 10 comprises two arms 12 drawn longitudinal oscillations whose first ends 14 are each hinged relative to a member (not shown) of vehicle body structure.
- the first ends 14 comprise for example a ball 16 which is received in a cage (not shown) integral with the vehicle body structure element.
- Intermediate portions 20 of the arms 12 are connected to each other by a crosspiece 22, and second ends 24 each receive a substantially wheel-shaped wheel support 26 in a substantially vertical axis "A".
- the wheel supports 26 comprise arms 28 which are each connected to first ends 30 of rods 32 whose second ends 34 are connected to a first end 36 of a spreader 38 which is pivotally mounted on the crosspiece 22 around a pivot 18 and whose second end 40 is intended to be moved by an actuator 42.
- the crosspiece 22 is made from a stamped sheet metal, and it comprises in the central part specific stampings and punchings (not shown) for fixing the central pivot 18 of the spreader 38.
- the invention overcomes this disadvantage by proposing a support means of the rudder 38 and the actuator 42 which can be grafted on a cross member 22 different from the naked cross described above
- the invention provides an axle 10 of the type described above, characterized in that the spreader 38 and the actuator are carried by a housing 44 which is attached to the cross member 22 axle 10 and which is mechanically decoupled from said crossbar 10.
- the housing 44 has a first end 46 which is fixed to one of the arms 12 of the axle 10, a tubular intermediate portion 48 which is arranged without contact around the cross member, and a second tubular end 50 which internally receives a resilient member 52 interposed between the housing 44 and the associated portion of the cross member 22.
- the cross-member 22 is preferably made by stamping a tubular profile of closed section so as to conform it after stamping in a section generally having the shape of a blank.
- the resilient member 52 is preferably made of an elastic shim of elastomeric material which is arranged around the U-shaped section of the sleeper 22 in the second tubular end 50 of the casing 44.
- the wedge 52 locally surrounds the cross member 22 of the axle so as to provide a fixing of the housing 44 which is capable of absorbing the games resulting from the torsion of the crosspiece 22 during the movements of the suspension.
- the intermediate portion 48 of the housing 44 receives at least one anchor point 54 of the actuator 42.
- this anchor point consists of a tab 54 which is welded to the casing 44 and which is intended to be traversed by a pin 56 for fixing the actuator 42.
- the second end 50 of the housing 44 externally receives a pivot 18 of the pivoting bar, arranged substantially in line with the spacer 52.
- the housing 44 has a first upper shell 58 and a second lower shell 60 which are assembled to one another. As illustrated in FIG. 4, the first and second shells 58, 60 delimit a tubular cavity 62 receiving the crosspiece 22.
- the wings 62, 64 may in particular be assembled to one another by welding.
- a first transverse end of each shell 58, 60, associated with the first transverse end 46 of the housing 44 comprises at least one means 66 for fixing to a fixed plate 68 at one of the arms 12 of the axle 10.
- This section "U” shaped is intended to receive a branch 78 of the plate 68 between its opposite branches 74, 76.
- the adjoining branches 70, 72 of the first ends of each shell 58, 60 each comprise a hole 66 forming the fixing means.
- This bore 66 is intended to be traversed by a fixing screw (not shown) which is received in a prison nut integral with the plate 68.
- the invention therefore provides a housing 44 for supporting the rudder 38 and the actuator 41 of a steering rear axle 10 in a simple, efficient manner.
- This attachment makes it possible to overcome effectively the twisting of the crossbar 22 of the axle, which ensures a high precision of the steering control of the axle 10.
