Abstract

Provided is a vehicle comprising a frame (160), outer axles (118a, 118c) and a middle axle (118b) disposed therebetween, each of the axles being mounted inside said frame (160) on a respective spring suspension (142) with springs (132), and a traction motor (110) coupled only to outer axles (118a, 118c). Only in the suspension (142) of the middle axle (118b) the springs (132) have movable spring seats (138) linked to said springs and configured to adjust the length of said springs to change preloading of the springs (132). Further, the vehicle includes an actuator (170, 1170) connected to said movable spring seats (138) and configured to move said spring seats (138) to adjust the length of the springs; and a controller (114) coupled to said actuator (170, 1170) to control the actuator for adjusting the length of said springs, the actuator being connected on the outer side of the frame. Also provided is a method for dynamic weight redistribution in the above-described vehicle (100) comprising steps of adjusting the length of springs (132) in the suspension (142) of the middle axle (118b) by means of the actuator (170, 1170) to provide variable preloading of the springs and redistribution of the springs preload between axles (118a, 118b, 118c) of the vehicle (100).
