"Suspension device with torsion bar for motor vehicles" "

The present invention relates to a suspension device with torsion bar for motor vehicles, in which each wheel is at least partially carried by an arm which has one end a longitudinal torsion bar is firmly connected, while the other end of this torsion bar on the cross member of the chassis frame hinged and firmly connected to one end of a transverse lever arranged perpendicular to the torsion bar, the other end of this lever3 on a cross member of the 3 chassis frame

adjustable is anchored »

Various suspension devices of this type with a torsion bar are already known. Such a device is in fact, filed in the French patent on 14 February 1966 at the name of Societe des Automobiles Simca described with the N ⁰ 1,476,691.

With this type of suspension, since the torsion bar has a large tolerance range, it is necessary that the transversely directed lever is brought into an exact angular position. For this purpose the adjusting lever is held supported by one of its ends against a nut with a spherical scope, which nut is screwed on a threaded shank, which in turn is attached to a cross member of the chassis frame, a device is _o with double fluted socket also enables a first relatively precise angular position of the lever in relation to the cross member before the nut is screwed on, _etc.

The present invention relates to improvements in the Installation of the lever, which simplifies the assembly operations of the vehicles on the production chain.

According to a further characterizing feature of the present invention, the joint of the torsion bar consists exclusively of the cross member. from an open cavity or cradle which is provided on the upper portion of the cross member and in which the end of the torsion bar firmly connected to the lever fits tightly and is held in this position and only under the action of Drehbeanspraeirang the torsion bar and the counteraction of the lever on the cross member, as well as the weight of the vehicle.

'Because the cross member is advantageously channel-shaped or inverted TJ is profiled, the lever is at least partially supported between the side walls of the channel-shaped cross member,

Since the lever, as known per se, is firmly connected to the cross member by a bolt arranged on the latter, its free End is hinged to the lever with the help of a joint head, which in turn adjusts the rotational restoring torque of the torsion bar is made possible by the lever, according to another feature of the invention at its end such a fork-shaped design that it can accommodate the joint head by the passage of the bolt zxiischen the Legs of the fork is made possible.

It is therefore not thanks to the improvements of the invention more necessary, in the cross member a hole for inserting a Provide bearing for the rotation of the torsion bar. The manufacture of the

Cross member is therefore, simplified assembly on the manufacturing chain is also significantly simplified, since the torsion bar firmly connected to the suspension arm of the wheel is simple is supported in its cradle, which serves as a bearing provided below the cross member without being used in this bearing needs to be. The adjustment lever can then be used on the torsion bar at any time «, thanks to the fork-shaped design of its free end, know the lever on the firmly connected to the cross member Adjustment bolts can be put on quickly and easily, the nut may already be arranged

-Other purposes, advantages and features of the invention will be will be explained more clearly in the following detailed description, which refers to the accompanying only given by way of example Drawings related

Show in the drawings;

- Figure 1 is a schematic representation in perspective Demolition showing the installation of a suspension device with a torsion bar on a cross member, which is passed through a longitudinal member of the chassis frame is worn, reveals;

- Figure 2 is an enlarged plan view with partial sections and torn off, which runs essentially along the axis of the cross member of Figure 1;

- Figure 3 is a view essentially according to the arrow III of Figure 2;

- Figure 4 is an enlarged view in perspective, showing the formation of the cross member at the anchoring point of the lever of the torsion bar.

According to figure 1, 10 is a longitudinal member of the chassis frame is shown, to which the end 11 of a cross member 12 is attached _o A wheel 13 is fixedly connected to a suspension arm 14 which with the fixedly connected 15 in turn one end of a torsion bar, wherein the the other end 16 of the torsion bar 15 is articulated on the cross member 12 and is firmly connected to a lever 17 _o .

As can be seen better in FIGS. 2 and 3, the articulated connection of the end 16 of the torsion bar 15 on the cross member 12 of the chassis frame by the simple support of this torsion bar end guaranteed in a cavity, which is designed as a cradle 50 and is provided on the lower portion of the cross member 12 only by the torsional stress 01 of the torsion bar 15 and by the Counter torque 02 the lever 17 on the cross member 12, as well as by the

It has been explained in this patent application that the cross member 12 is mounted on the longitudinal members 10 by simply inserting its ends 11 in a metal crucible 19, the metal crucible 19 being welded to the inside 22 of the longitudinal member 10 after a damping element 24 made of rubber has been interposed ¹ In this patent application it has been explained how the cross member 12 is simply inserted in this way and united with the side members by engaging each end 11 of this cross member in the crucible 19 by hurried pressure exerted on the cross member from back to front. In FIG. 2, the rear part is indicated by the letters AR and the front part by the letters AV

Characterized in that according to the present invention, the lever 17 on the torsion bar 15 is locked because it is through its end 55 between the side surfaces 65, 66 of the cross member 12 inserted at least partially is actually prevented any movement of the cross member 11, by achieving an additional safety lock for the cross member on the side members
