FIELD: mechanical engineering. ^ SUBSTANCE: proposed crawler vehicle consists of body accommodating independent drives of motor-sprockets and levers, track bogies connected with body for turning relative to body around their axles aligned with axles of rotation of motor-sprockets engaging with track guide. Track bogies consist of levers connected to vehicle body for rocking relative to body around axles aligned with axles of rotation of motor-sprockets. Axle is secured between ends of levers non-coupled with motor-sprockets. Said axle is parallel to axle of rotation of motor-sprockets, and connecting rod is installed on said axle for rocking. Cheeks are hinge-connected in middle part of levers. Roller is secured for rotation on side surface of one of cheeks nearest to body. Wheels are installed for rotation on end of levers, connecting rod and cheeks. Guides of roller are arranged on side surfaces of vehicle body. Ends of tie-rods are secured in middle part of connecting rod for rotation. Opposite ends of said tie-rods are installed on cheeks for free displacement within the limits of cheek slot. Axes of rocking of connecting rod, cheeks, rotation of roller, wheels and tie-rods are parallel to axes of rotation of motor-sprockets. ^ EFFECT: elimination of drawbacks of four-track vehicles at preservation of profile passability. ^ 19 dwg |
