Abstract
The invention relates to a steering-mode gear transmission of a wheeled locomotive, and relates to steering gear transmission of wheeled locomotives. By the aid of the steering-mode gear transmission, wheels on two sides of the locomotive can reversely rotate, a locomotive body can be pivotally steered or turned around, the shortcoming that a wheeled locomotive in the prior steering art cannot be steered or turned around in narrow places or roads can be overcome, and the wheels on the two sides of the wheeled locomotive can mutually reversely rotate, and the locomotive body can be pivotally steered when places or roads are narrow. The steering-mode gear transmission comprises two steering gear transmission mechanisms which are connected with an existing transmission system. One end of a spline shaft (38) and one end of a spline shaft (39) of steering mechanisms are respectively connected with existing half-axle gears (5) and (6), and spline holes in one end of a bevel gear (25) and one end of a bevel gear (22) are respectively connected with spline heads of existing half axles (11) and (12). The steering-mode gear transmission has the advantages that the two steering mechanisms are respectively provided with steering gear control mechanisms with identical principles and structures, the locomotive can be turned, forwardly straightly move and backwardly straightly move under the control of the steering gear control mechanisms, and the wheels on the two sides of the locomotive can reversely rotate, so that the locomotive can be pivotally steered.
