VEHICLE POLLUTION-FREE CRAWLER PROPULSIVE UNIT Russian patent published in 2000 - IPC

FIELD: transport engineering; crawler vehicles. SUBSTANCE: long-base vehicle pollution-free crawler propulsive unit has link tracks bending in horizontal plane (in plan) made up of rigid links with central horns. Track links are connected to each other by horizontal cross joints. Track link has two parts opposite in length with wedge bevels of opposite end faces. Guide horn is sectional, made in form of vertical joint. The latter should be preferably made as stepped pyramidal member. Tracks are laid over wheels and rolls installed for turning of their axles in azimuth around vehicle kinematical turning center. Provision is made for mounting wheels independently and rolls in pairs on carriages intercoupled by vertical joints and coupled with steering gear. EFFECT: improved conditions of turning of crawler vehicle owing to bending of tracks in horizontal plane, enhanced maneuverability, reliability, economy and ecological characteristics of tracks and propulsive unit as a whole, increased service life. 3 cl, 5 dwg
