Abstract
The present invention relates to a suspension arrangement for a tracked vehicle. The suspension arrangement includes a road wheel arm having a wheel axle portion for supporting a wheel of the vehicle and a pivot axle portion. The road wheel arm is pivotably journalled at the pivot axle portion to a housing that is fixable to the vehicle body. A torsion bar is connected to the pivot axle portion and a torsion tube is arranged to be connected to the vehicle body, with the torsion bar running through the torsion tube and arranged to be connected to the torsion tube. The modulus of elasticity of the torsion tube material is lower than the modulus of elasticity of the torsion bar material such that the maximum suspension travel is increased.
Claims11
A suspension arrangement for a tracked vehicle, said suspension arrangement comprising:
- a road wheel arm having a wheel axle portion configured to support a wheel of the vehicle and a pivot axle portion, the road wheel arm being pivotably journalled at said pivot axle portion to a housing configured to be fixed to a vehicle body;
- a torsion bar being connected to the pivot axle portion;
- and
- a torsion tube being arranged to be connected to the vehicle body, said torsion bar running through the torsion tube and being arranged to be connected to the torsion tube, wherein a modulus of elasticity of the torsion tube material is lower than a modulus of elasticity of the torsion bar material so as to increase the maximum suspension travel.
