  • Torsion axle suspension system apparatus and method
    Patent number: 12441154
    Abstract: A torsion axle assembly for supporting of a vehicle body on an undercarriage, including an elongated inner member having an inner member longitudinal axis; a torsion arm interconnected with the elongated inner member and the undercarriage; an elongated enclosure interconnected with the vehicle body and having an interior space; and resilient material residing within the interior space to support the elongated inner member within the interior space, such that the inner member longitudinal axis resides at an unloaded camber angle to an elongated enclosure longitudinal axis when none of the weight of the vehicle body is borne by the torsion axle assembly and at a loaded camber angle when the weight of the vehicle body is borne by the torsion axle assembly, such that the unloaded camber angle is greater than the loaded camber angle. A vehicle having such a torsion axle assembly and a method are disclosed.

  • Torsion axle suspension system apparatus and method
    Patent number: 12083849
    Abstract: A torsion axle assembly for supporting of a vehicle body on an undercarriage, including an elongated inner member having an inner member longitudinal axis; a torsion arm interconnected with the elongated inner member and the undercarriage; an elongated enclosure interconnected with the vehicle body and having an interior space; and resilient polymeric material residing within the interior space to support the elongated inner member within the interior space, such that the inner member longitudinal axis resides at an unloaded camber angle to an elongated enclosure longitudinal axis when none of the weight of the vehicle body is borne by the torsion axle assembly and at a loaded camber angle when the weight of the vehicle body is borne by the torsion axle assembly, such that the unloaded camber angle is greater than the loaded camber angle. A vehicle having such a torsion axle assembly and a method are disclosed.
