The invention relates to a crawler-type quick-change walking system for an automobile. The crawler-type quick-change walking system comprises a bearing vertical frame, a driving shaft, an oil-gas automatic tensioning mechanism, and a thrust wheel assembly, wherein the driving shaft is arranged on the bearing vertical frame, and a flange plate and a driving wheel are arranged on the driving shaft;the oil-gas automatic tensioning mechanism is arranged on the bearing vertical frame and includes a tensioning rocker arm, a lower connecting pin, an oil cylinder main body, a limiting pin, a high-pressure energy accumulator, a mounting base, an inflation valve, an oil cylinder mounting groove, a bearing support, a reinforcing rod, a piston rod, an upper connecting pin and a tensioning wheel connecting piece; and the thrust wheel assembly includes a swing shaft, a front herringbone support, a rear herringbone support, a driven thrust shaft and a thrust wheel. A crawler belt is always kept in aproper tensioning state through the tensioning device, problems of impact and vibration generated in a high-speed running process of a rescue vehicle can be effectively solved, and the stability performance, operation comfort and safety of the crawler vehicle are improved.
