- Kzt being the contribution of the torsion of the cylindrical elastic joints to the stiffness of the primary suspension relative to the wheel
- KAr being the radial stiffness of the cylindrical elastic joints
- KPc being the stiffness in compression of the elastic member 38
- KPs being the shear stiffness of the elastic member 38
- L being the length of the connecting rods between the first connection point and the second connection point
- each of the connecting rods 26 and 28 tends to pivot about a substantially vertical axis with respect to the axle box 14 at its second point of articulation, and also with respect to the frame 16 at its first point of articulation.
- the end of axis 56 of the connecting rod will tend to be offset relative to the cylindrical housing 58, by pivoting about a vertical axis (see arrow ⁇ of Figure 3).
- the transverse stiffness of the primary suspension with respect to the wheel is expressed as follows:
- Kya being the contribution of the axial stiffness of the cylindrical elastic joints to the transverse stiffness of the primary suspension

- the primary suspension device At rest, has a height substantially equal to 300 mm.
- the suspension device described above has many advantages.
- rubber-metal sandwiches can work in compression as well as in shear, while a coil spring can only work in compression. It is thus possible to arrange the rubber-metal sandwich-type elastic member with a ⁇ angle significantly different from 90 °, which goes in the direction of reducing the height of the suspension.
- the suspension device can take up more load vertically than with an elastic member consisting of a coil spring.
- each primary suspension device may for example have a height of between 200 mm and 400 mm, preferably between 250 mm and 350 mm and typically equal to 300 mm.
- a preferred position of the rods is to offset them longitudinally symmetrically on either side of the axle, which allows to load the rods equitably in the event of vertical stresses on the wheels in the case where the elastic member is located equidistant between the first connecting points of the connecting rods, as explained above.

- the elastic member may be offset with respect to the connecting rods upwards, downwards, left or right relative to the position illustrated in FIG.
- the connecting rods 26 and 28 may be linked by their respective second connection points 34 and 36 directly to the axles.
- the connecting rods can also be linked by their first point of connection to other fixed parts of the bogie, for example to braking members.
- the rods 26 and 28 may be connected by their second respective connection points 34 and 36 to the housing.
- the casing in this case, extends substantially over the entire length of the axle, from one wheel to another.
- the device may comprise several elastic members 38 interposed in parallel between the two connecting rods.
- the primary suspension devices may not be disposed inward of the truck relative to the wheels, but rather immediately to the outside of the truck relative to the wheels.
- the suspension device can be integrated in a secondary bogie suspension, the second element being in this case the chassis of the bogie, the first element being the body of the railway vehicle in the case of a non-pivoting bogie, and being the bolster the bogie in the case of a bogie pivoting relative to the body.
