CRAWLER TRACTOR RUNNING GEAR

摘要

FIELD: transport engineering; crawler tractors with flexible suspension. SUBSTANCE: device has bogies with larger and smaller equalizers hinge-coupled by rocking axle 3. Larger equalizer has socket for trunnion 4 hinge-coupling bogie with tractor frame. Equalizers have sockets in form of cylinders for orientation of spring 7 by external and internal diameters. Bottom of each socket has rectangular ports 8 and 9 whose exceeds diameter of middle portion of rod 10. Ends of rod are threaded. Stops are welded in middle portion of rod to engage with spring sockets. Nut with locknut, pair of spherical washers and aligning spacer 17 are mounted on end of rod. Opposite end of rod carries similar nut with locknut and second pair of spherical washers engaging with cup 20 mounted on rod end and enclosing two opposite cotters 21. EFFECT: possibility to increase rigidity of balancing bogies by locking the spring without demounting. 2 cl, 4 dwg
