Abstract
A multi-axle unit for a semi-trailer that is towed by a tractor vehicle and has at least three axles, at least one of the axles of the multi-axle unit being capable of being configured as a lifting axle and/or steered axle and all axles except for at least one axle being brakable and equipped with axle brakes having axle brake disks, the axle brake disks defining an effective frictional radius that is the same as an effective frictional radius of brake disks of the tractor vehicle. The multi-axle unit, due to the particular configuration of its braking system, has a lower unsprung mass, requires less maintenance outlay, and moreover is more economical to purchase and maintain.
