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).
A load transfer arrangement for a vehicle including a chassis with at least one braked axle, the arrangement comprising:
A method for transferring load between at least one braked axle and a non-driven, unbraked axle of a chassis of a vehicle, wherein the non-driven, unbraked load axle is suspended by an air suspension assembly including at least one air cushion arranged between the chassis and the non-driven, unbraked load axle in order to transfer load from the braked axle(s) to the non-driven unbraked load axle, characterized by the steps of:
