FIELD: transportation.
SUBSTANCE: invention is related to steering mechanisms of wheel transport and traction machines, and may also find application in motor industry, tractor construction, machine-tool construction, instrument making, production of weight-lifting machines, where mechanisms are required with preset patterns of their separate work members movement. Steering mechanism comprises tooth gear with master gear (1) and tooth rack (6). Tooth rack (6) is made in the form of two parallel parts that move one along each other. Teeth (7) of racks are installed with the possibility of alternate engagement with gear in radiuses of its dividing circumferences, which makes it possible to obtain an alternation transmission ratio.
EFFECT: makes it possible to improve controllability of transport vehicle due to provision of optimal pattern for variation of transmission ratio of rack steering mechanism, and also to increase traffic safety.
