Definitions
- the present invention relates to a system for assisting the mounting of a rear axle of a motor vehicle, and a method of mounting the rear axle with the aid of such a tool.
- Motor vehicles generally include a rear axle fixed under the body, which supports and guides the rear wheels by allowing a movement of the suspensions.
- a known type of rear train called deformable cross train presented in particular by the document FR-A1 -2888559 comprises an axle having a generally "H" shape, comprising on each side of the vehicle a longitudinally disposed suspension arm.
- the front of the suspension arms is connected to the vehicle body by a hinge comprising an elastic connection pivotable along a substantially transverse axis, the rear of these arms supporting the hub of the wheel.
- the central bar of the "H" is a transversely deformable cross member, each end of which is rigidly fixed inside the suspension arms.
- This deformable crosspiece maintains the geometry of the suspension arms, while ensuring torsional deformation along its axis, the anti-roll bar function which limits the roll angle of the body.
- the vehicle body is supported by suspension springs which rest on a tray forming a basket disposed at the rear of each arm, the inner side.
- a telescopic hydraulic damper is installed in parallel, inside or on the side of this spring.
- a known type of tool presented in particular by the document FR-A1 -298961 1, comprises a spring suspension clamp to compress the spring, and bring the suspension arm to the correct height for mounting the 'damper.
- the present invention is intended to avoid these disadvantages of the prior art.
- a system for assisting the mounting of a rear axle of a motor vehicle comprising longitudinal arms fixed by front joints to the vehicle body, and suspension springs attached to these arms, characterized in that it comprises a rigid strap in retaining traction comprising at each end means for hooking on the body and on the train, and an elastic element fixed in parallel with this rigid strap which tends to bring the fastening means closer, the strap rigid tension tensile being provided to achieve a maintenance of the rear axle in a low reference position.
- An advantage of this system is that quickly, simply and economically, by hooking the strap between the body and the train during the attachment of the front linkage axes, taking advantage of the tool holding the train in this position fixing, we obtain a security that prevents the tilting of this train down around the joints beyond the low reference position, by a restraint of this rigid strap tensioned, comprising the elastic member extended.
- This low position is provided to ensure the safety of the various elements attached to the train or surrounding, not to damage them.
- the elastic element arranged in parallel maintains a slight traction on the attachment means, which avoids an unexpected detachment of these means.
- the mounting aid system according to the invention may further comprise one or more of the following features, which may be combined with each other.
- the reference low position of the rear axle substantially corresponds to the beginning of compression of the suspension springs.
- the attachment means on the vehicle body may include a fastening hook having a global shape "U", comprising a side which terminates in a projection provided to maintain a member of this body.
- the attachment means on the rear axle may comprise a fixing hook provided to engage in a recess of the rear axle.
- the elastic element forms an elastic strap which is arranged flat on the rigid strap in tension.
- the invention also relates to a method of mounting a rear axle of a motor vehicle, comprising longitudinal arms fixed by front joints to the vehicle body, and suspension springs and dampers attached to these arms, to using a mounting assistance system comprising any one of the preceding features, comprising the following operations: - The rear axle being held in a fixing position by a tool that positions, the front joints of this train are fixed, and the mounting system is hooked to the box and the train;
- FIG. 1 is a view of a mounting system according to the invention, in a relaxed position
- FIG. 1 is a view of this system in its extended position
- FIG. 3 is a view of a rear axle with a deformable cross member receiving this system in a relaxed position
- FIG. 4 is a view of the rear train receiving this system in its extended position by a traction F.
- FIGS. 1 and 2 show a rigid traction strap 8 comprising, on the left, a fixing hook on the body of the vehicle 2, and on the right a fixing hook on the rear axle 4, forming the system for assisting with the assembly of this train. back.
- the body hook 2 has a global "U" shape, comprising a small side engaged in a loop of the strap, which ends with a holding boss 10, and a large parallel side which also terminates in a boss 12 ensuring a maintenance on an element of the body after the engagement of this hook on this element.
- the train hook 4 has on one side a first hook 14 engaged in a loop of the strap, and on the other side a second hook 16 provided to engage in a recess of the rear axle.
- the rigid strap in tension 8 receives in parallel an elastic element 6 in the form of a strap fixed flat on this rigid strap, which tends to bring the two fastening hooks 2, 4.
- the two straps 6, 8 are arranged in the same plane as the two fastening hooks 2, 4.
- Figure 3 shows a rear axle comprising a longitudinally disposed suspension arm 20, which is fixed at the front to the vehicle body by a ring having an elastic articulation 22 disposed along a substantially transverse axis A.
- the rear part of the suspension arm 20 comprises a cup 24 receiving the lower support of the suspension spring not shown, and a vertical plate receiving the hub 26 of the rear wheel 40.
- the rear axle comprises a deformable cross member 38 arranged transversely, which rigidly connects the two suspension arms 20.
- a hydraulic telescopic damper 28 held in a position partially compressed by a belt 30 disposed along its body, and passing over its ends, has a base 42 attached to the rear axle, and an upper end provided to be secured below of the vehicle body.
- this train In a fixing operation of the rear axle, this train is held in a fixing position by a tool which positions it under the vehicle body, while an operator installs the axes of the elastic joints before 22.
- FIG. 4 shows the rear axle after a withdrawal operation of the positioning tool of this train, the front elastic joints 22 being fixed under the vehicle body.
- this precise reference position maintained by the tension of the rigid strap in tension 8 ensures the safety of the various elements fixed on this train or arranged in the environment, in particular pipes, avoiding a tearing that could be caused by a complementary tilt of this train.
