VEHICLE SUSPENSION Russian patent published in 1996 - IPC

FIELD: transport engineering; running gears of crawler vehicles. SUBSTANCE: unidirectional equalizers 3,6 (or 4,5) of bogies of each side have levers 14 with axles 15 interconnected by longitudinal tie-rod 16. Axles of levers are parallel with equalizer rocking axles 7 forming parallelogram with the latter. Proposed is longitudinal tie-rod 16 of different design versions: 1) tie rod consisting of two parts connected by flexibly damping member which can be made in form of coil spring 17 or hydraulic shock absorber installed separately or together; 2) tie-rod in form of leaf spring; 3) rigid tie rod. In each case longitudinal tie-rod can be furnished with additional adjusting bushing. EFFECT: increased angular rigidity of suspension without increase in its vertical rigidity. 7 cl, 4 dwg
