Claims
- 1. A vehicle axle crosspiece, comprising:
a first tube having an axis of elongation, the first tube being adapted to have one axial end thereof connected to a first wheel arm situated on one side of a vehicle and the other axial end thereof extending towards the other side of the vehicle; a second tube extending in part axially within the first tube, the second tube being adapted to be connected at the axially outer end thereof to a second wheel arm situated on the other side of the vehicle; at least two antiroll articulations of elastomeric material joining the first and second tubes together, the at least two antiroll articulations being spaced apart in the longitudinal direction of the tubes and being housed between the outside surface of the second tube and the inside surface of the first tube; each of the at least two antiroll articulations having its own radial stiffness and being assigned a coefficient proportional to the respective radial stiffness; and the center of inertia of the at least two antiroll articulations is closer to the first wheel arm than to the second wheel arm.
- 2. The axle crosspiece as claimed in claim 1, wherein the radial stiffness of the antiroll articulation closest to the first wheel arm is greater than the radial stiffness of the articulation closest to the second wheel arm.
- 3. The axle crosspiece as claimed in claim 1, wherein the radial stiffness of the antiroll articulation closest to the first wheel arm is at least 20% greater than the radial stiffness of the antiroll articulation closest to the second wheel arm.
- 4. The axle crosspiece as claimed in claim 1, wherein the radial stiffness of the antiroll articulation closest to the first wheel arm is at least 35% greater than the radial stiffness of the antiroll articulation closest to the second wheel arm.
- 5. The axle crosspiece as claimed in claim 1, wherein the geometric center of the at least two antiroll articulations is offset to the side of the first wheel arm.
- 6. The axle crosspiece as claimed in claim 5, wherein the distance from the geometric center of the at least two antiroll articulations to the first wheel arm is less than 0.45 L, where L denotes the length of the crosspiece.
- 7. The axle crosspiece as claimed in claim 1, wherein the distance between the at least two antiroll articulations is between 0.3 L and 0.6 L, where L denotes the length of the crosspiece.
- 8. A vehicle axle, comprising:
a first wheel arm situated on one side of the vehicle; a second wheel arm situated on the other side of the vehicle; a first tube having an axis of elongation, the first tube being connected at one axial end thereof to the first wheel arm and the other axial end thereof extending towards the other side of the vehicle; a second tube extending in part axially within the first tube, the second tube being connected at the axially outer end thereof to the second wheel arm; at least two antiroll articulations of elastomeric material joining the first and second tubes together, the at least two antiroll articulations being spaced apart in the longitudinal direction of the tubes and being housed between the outside surface of the second tube and the inside surface of the first tube; each of the at least two antiroll articulations having its own radial stiffness and being assigned a coefficient proportional to the respective radial stiffness; and the center of inertia of the at least two antiroll articulations is closer to the first wheel arm than to the second wheel arm.
- 9. The vehicle axle as claimed in claim 8, wherein the radial stiffness of the antiroll articulation closest to the first wheel arm is greater than the radial stiffness of the articulation closest to the second wheel arm.
- 10. The vehicle axle as claimed in claim 8, wherein the radial stiffness of the antiroll articulation closest to the first wheel arm is at least 20% greater than the radial stiffness of the antiroll articulation closest to the second wheel arm.
- 11. The vehicle axle as claimed in claim 8, wherein the radial stiffness of the antiroll articulation closest to the first wheel arm is at least 35% greater than the radial stiffness of the antiroll articulation closest to the second wheel arm.
- 12. The vehicle axle as claimed in claim 8, wherein the geometric center of the at least two antiroll articulations is offset to the side of the first wheel arm.
- 13. The vehicle axle as claimed in claim 12, wherein the distance from the geometric center of the at least two antiroll articulations to the first wheel arm is less than 0.45 L, where L denotes the length of the crosspiece.
- 14. The vehicle axle as claimed in claim 8, wherein the distance between the at least two antiroll articulations is between 0.3 L and 0.6 L, where L denotes the length of the crosspiece.
