VEHICLE STEERING MECHANISM (VERSIONS) Russian patent published in 2005 - IPC

FIELD: transport engineering; wheeled and crawler vehicles.

SUBSTANCE: proposed mechanism includes drive shaft with drive from axle drive, right-hand and left-hand drive shafts of final drives coupled with drive shaft through corresponding friction clutches, additional shaft parallel to drive shaft and connected with right-hand and left-hand drive shafts of final drives through two gear trains. Idler wheel is built into one of gear trains, right-hand or left-hand or left-hand one. Other gear train is furnished with controllable clutch to form rigid kinematic coupling between all drive shafts and additional shaft at cornering. According to other design version, idler wheel and controllable clutch are built into one of gear trains, right-hand or left-hand ones.

EFFECT: improved steerability at straight-ahead motion, increased efficiency of transmission, reduced actions required from driver, simplified design of steering mechanism.
