Self-adaptation traction force automatic control transfer case

The utility model relates to a self-adaptation traction force automatic control transfer case, this transfer case include the smooth ware of power output gear pair, differential mechanism and accuse, the smooth ware of this accuse is installed in this differential mechanism, and this differential mechanism is equipped with one-way separation and reunion structure respectively with the smooth ware of accuse. The utility model discloses an inside fast poor the interference does not take place for self-adaptation traction force automatic control transfer case, drive efficient, fuel sparingly. Do not receive the interference of electromagnetic wave, salt fog, the difference in temperature, the adaptation face is wide, without electronics and manual control, but the required moment of torsion drive automobile walking of the condition of adhering to of each wheel of automatic adjustment, and each wheel driving power can reach the optimum, has improved the utilization ratio and the complete all-weather operating condition of topography of power greatly, it is applicable in all kinds of large-scale truck and pony cars more than 44.
