Vehicle Axle Suspension, And Vehicle Comprising Such Vehicle Axle Suspension

A vehicle axle suspension for a vehicle chassis, comprising:

• a tubular axle body having a longitudinal axis;
• resilient suspension arms extending in a longitudinal direction of the vehicle on both sides of the vehicle, and crossing the axle body substantially perpendicular, the resilient suspension arms having an upper side and a lower side;
• bearing brackets arranged on the vehicle chassis, wherein each suspension arm is hingedly connected at a front portion, viewed in a direction of travel of the vehicle, to one of the bearing brackets;
• a pneumatic spring for each suspension arm being operational between the respective suspension arm and the vehicle chassis;
• and
• a clamping assembly associated with each suspension arm, wherein the axle body and the suspension arm are tightened together by the clamping assembly, the clamping assembly comprising at least one upper clamping body engaging the suspension arm and at least one lower clamping body engaging an underside of the axle body;
• wherein the suspension arm comprises a recess on the upper side of the suspension arm to receive at least a portion of the at least one upper clamping body, wherein the recess defines an upwardly facing engagement surface where the at least one upper clamping body engages with the suspension arm, the engagement surface being located at or near a neutral plane of the suspension arm, such that the at least one upper clamping body engages with the suspension arm at or near the neutral plane of the suspension arm, the neutral plane of the suspension arm being the location where the movement of the suspension arm due to bending about an axis parallel to the longitudinal axis of the axle body is minimal.

A vehicle axle suspension of a vehicle, comprising:

• an axle body;
• a resilient suspension arm extending in a longitudinal direction of the vehicle and crossing the axle body substantially perpendicular, the suspension arm having an axle seating portion receiving the axle body;
• a bearing bracket arranged on a vehicle chassis, wherein the suspension arm is hingedly connected at a front portion, viewed in a direction of travel of the vehicle, to the bearing bracket;
• a pneumatic spring being operational between the suspension arm and the vehicle chassis;
• at least one clamping assembly clamping the axle body and a trailing portion of the suspension arm together at the axle seating portion, the clamping assembly comprising a U-bolt extending around an underside of the axle body and a clamping body located at an upper side of the axle seating portion of the suspension arm, the clamping body extending in a transverse direction over an upper side of the suspension arm, the clamping body having on either side a lateral portion provided with a bore for passing through an upwardly extending leg of the U-bolt, the clamping body further comprising a connecting portion interconnecting the lateral portions of the clamping body,
• wherein the suspension arm has at either lateral side an engagement surface, providing a support surface for the lateral portions of the clamping body, wherein the clamping body is only supported at the lateral portions.
