Abstract:
The invention i.a. relates to a load transfer arrangement (10) for a vehicle (12) including a chassis (14) with at least one braked axle (16), the arrangement (10) comprising: a non-driven load axle (18), and an air suspension assembly (20) including at least one air cushion (22) arranged between the chassis (14) and the non-driven load axle (18) in order to transfer load from the braked axle(s) (16) to the non-driven load axle (18), wherein the non-driven load axle (18) is unbraked, and wherein the arrangement (10) further comprises: an evacuation controller (24) configured to provide a pressure release trigger in response to a current or predicted braking event of the vehicle (12), and at least one evacuation valve (26) configured to, in response to receiving the pressure release trigger, evacuate pressure from the at least one air cushion (22) in order to remove load from the non-driven load axle (18) and increase load on the braked axle(s) (16).
