The invention discloses a moving-track adjusting device of a front wheel of a vehicle. The moving-track adjusting device consists of a friction-wheel transmission mechanism and a space four-connecting-rod mechanism, wherein the input shaft of the friction-wheel transmission mechanism and a rear wheel of the vehicle have a fixed transmission ratio, and the transmission ratio of the input shaft to a transmission shaft can be changed through the change of the axial position of a friction wheel shaft, so that the change of the swinging transmission ratio of the front wheel to the rear wheel from infinitely great to infinitely small can be realized in theory; the space four-connecting-rod mechanism can change the swinging angle of the front wheel through the adjustment of the radius of a crank, the length of a telescopic connecting rod, and the length of a threaded rod; the vehicle track is controlled through the cooperative adjustment of the friction-wheel transmission mechanism and the space four-connecting-rod mechanism. Compared with a manual control manner, the moving-track adjusting device disclosed by the invention realizes the accurate control of the moving track of the vehicle by adopting a simple structure design, and is good in adjustability; compared with an electronic control manner, the moving-track adjusting device adopts mechanical transmission, so that the running is reliable; besides, the moving-track adjusting device is simple in structure and low in manufacturing cost.
