The invention discloses a multi-axle vehicle and a double-front-axle gear and rack type steering system thereof. The steering system comprises a steering shaft, two commutators, two gear and rack steering devices and a universal transmission shaft; an input port of the first commutator is connected with the steering shaft, an input port of the first gear and rack steering gear is connected with a first output port of the first commutator, and two output ports of the first gear and rack steering gear are in transmission connection with steering wheels on the two sides of the first shaft; two ends of the universal transmission shaft are respectively connected with a second output port of the first commutator and an input port of the second commutator; an output port of the second commutator is connected with an input port of the second gear and rack steering gear; and two output ports of the second gear and rack steering gear are in transmission connection with steering wheels on the two sides of the second shaft respectively. The two gear and rack steering gears are reasonably controlled by a steering wheel through structure optimization, the structure is simple and reliable, the transmission efficiency is high, and the transmission smoothness and the operation stability can be comprehensively guaranteed.
