The invention discloses a telescopic bridge used for vehicles. The telescopic bridge is characterized by being composed of a hydraulic cylinder (9), a left cover (1), a right cover (2), a left clamping device (7) arranged outside the contact end of the left cover (1) and the right cover (2) and provided with a through hole, a right clamping device (8) arranged on one side of the right cover (2) and provided with a through hole, a driving drive axle shaft (3) arranged in the left cover (1), and the like. A control system of the telescopic bridge is characterized by being composed of the hydraulic cylinder (9), an oil tank (13), a three-position four-way electromagnetic reversing valve (17), an oil filter (14), a check valve (16), an oil conveying overflow valve (27), and the like. By means of the telescopic bridge, the wheel interval can be adjusted; the wheel interval can be decreased when vehicles encounter narrow roads or bridges during driving, and therefore the vehicles can conveniently pass. The wheel interval increasing and decreasing time is short, accuracy is high, abrasion between parts in the stretch-out and draw-back process is quite small, and the service life can be prolonged.
