STABILISER OF COURSE OF VEHICLE CHASSIS MOVEMENT ON STEPS Russian patent published in 2015 - IPC A61G5/06 B60T7/12 

FIELD: transportation.

SUBSTANCE: stabiliser of course of vehicle chassis movement on steps includes spring-loaded left and right braking levers (BL) spaced in pairs along the width of the chassis with left and right spring-loaded braking pairs. There is a possibility of independent rotation of BL in longitudinal vertical planes on hinged joints with a common transverse axis under action of forces of reaction of their interaction with a step. There is a possibility of independent board braking of chassis at the specified angular position of BL due to automatic connection of braking pairs. The chassis includes a bearing structure, a propeller and a propulsion plant. The transverse axis is installed as thrusting between boards of the bearing structure. Coaxially to it on the bearings there is a shaft installed as split slantwise, forming board half-shafts with a thrust bearing on their joint in the specified slant cut. Half-shafts and BL are spring-loaded with a pair of thrusting return springs in the axial direction and a pair of thrusting return springs in rotation of the BL around the axis. Each braking pair is built-in between the appropriate half-shaft and the board of the bearing structure of the chassis. BL are fixed by their bases to half-shafts and pressed, via them, by the second pair of springs to stops-limiters of rotation.

EFFECT: increased course stability of climbing staircases and overcoming single profile obstacles, such as steps.
