Suspension of a vehicle axle and vehicle
A suspension is provided for a vehicle axle, with a twist-beam axle having two trailing arms interconnected via a cross brace, of which each trailing arm comprises a mounting device for the rotatable fastening of the twist-beam axle to a vehicle body, which includes, but is not limited to a bushing and a connecting element, which is formed on the trailing arm and in which the bushing is received such that the twist-beam axle can be pivoted about the longitudinal axis of the bushing. The bushing is fastened to a holder, which can be connected to the vehicle body, and the bushing with its longitudinal axis is arranged in a horizontal vehicle plane.
1. A suspension of a twisted beam axle for a body of a vehicle, comprising:
a cross member of the body of the vehicle;
a Watt linkage;
having two trailing arms connected to the Watt linkage, wherein the Watt linkage further comprises a Watt linkage holder that is configured to connect the Watt linkage to the cross member of the body;
a brace interconnecting the two trailing arms;
a mounting device for each of the two trailing arms that is configured for a rotatable fastening of the twist-beam axle to the body of the vehicle;
a bushing formed on at least one trailing arm of the two trailing arms; and
a connecting element of the bushing that is also formed on at least one trailing arm of the two trailing arms and into which the bushing is received in such a manner that the twist-beam axle is configured to pivot about a longitudinal axis of the bushing; and
a holder fastened to the bushing that is configured to connect to the body of the vehicle, the axis of the bushing being arranged in a horizontal vehicle plane.
2. The suspension according to claim 1 ,
wherein the Watt linkage holder is a sleeve into which the bushing is pressed, and
wherein the sleeve comprises at least one reinforcing rib.
3. The suspension according to claim 1 , wherein the bushing with the longitudinal axis is arranged higher in the vehicle than an axis through a wheel center of a wheel suspension of the two trailing arms.
4. The suspension according to claim 1 , wherein the connecting element is fork-shaped.
5. The suspension according to claim 1 , wherein the connecting element is a U-shaped mount.
6. The suspension according to claim 1 , wherein the connecting element is unitarily connected with at least one of the two trailing arms.
7. The suspension according to claim 1 , wherein the Watt linkage holder is connected to a central link of the Watt linkage and comprises two arms that are configured to fasten to the cross member of the body.
8. The suspension according to claim 1 , wherein a cross brace of the twist-beam axle is a torsion profile that is stiff to bending and torsionally soft.
9. The suspension according to claim 1 , wherein a cross brace is rotatable relative to the two trailing arms.
10. The suspension according to claim 1 , wherein a cross brace is provided on the two trailing arms in a fixed position and non-adjustable.
11. The suspension according to claim 1 , wherein the two trailing arms are at least partially formed from a gray cast iron.
12. The suspension according to claim 1 , wherein the two trailing arms are at least partially formed from a steel plate.
13. The suspension according to claim 1 , wherein the two trailing arms are at least partially formed from a light metal.
14. The suspension according to claim 1 , wherein the two trailing arms are at least partially formed from an aluminum.
15. The suspension according to claim 1 , wherein the two trailing arms are at least partially formed from an aluminum alloy.
16. A suspension of a twisted beam axle for a body of a vehicle, comprising:
two trailing arms;
a spring absorber device fastened to one of the two trailing arms, the spring absorber device further comprising:
an absorber with an absorber mounting device and a spring seat;
a dome element with a first end and a second end,
wherein the absorber is received and is connected to the absorber mounting device, and is also fastenable to the body with the absorber mounting device at the first end,
wherein further the second end comprises another spring seat, which is fastened to the body of the vehicle, and
a spring element that is received in the spring seat of the dome element and the spring seat of the absorber;
a brace interconnecting the two trailing arms;
a mounting device for each of the two trailing arms that is configured for a rotatable fastening of the twist-beam axle to the body of the vehicle;
a bushing formed on at least one trailing arm of the two trailing arms; and
a connecting element of the bushing that are also formed on at least one trailing arm of the two trailing arms and into which the bushing is received in such a manner that the twist-beam axle is configured to pivot about a longitudinal axis of the bushing; and
a holder fastened to the bushing that is configured to connect to the body of the vehicle, the axis of the bushing being arranged in a horizontal vehicle plane.
