The invention relates to a carbon-free trolley steering gear, a fine adjustment long rod is connected with a cross rod through a fine adjustment nut, the cross rod is fixed on a front wheel support, the fine adjustment nut, the fine adjustment long rod, a rotational nut and the cross rod constitute a crank connecting link displacement fine adjustment system, the carbon-free trolley steering gear adopts a crank connecting link mechanism so as to realize trolley steering fine adjustment, by changing the relative positions of the fine adjustment nut and a fine adjustment crank rotation center shaft, the position of the fine adjustment nut, which is on the fine adjustment long rod, realizes the obstacle crossing requirement for different intervals within 700 millimeters to 1300 millimeters, as the crank connecting link mechanism does not have a sliding pair of a sine mechanism, the energy consumption caused by friction is reduced greatly, simultaneously, the precision prescribed is relatively lowered, and thus batch production can be realized.
