METHOD FOR INCREASED IN COMBAT VEHICLE CROSS-COUNTRY CAPACITY AND COMBAT VEHICLE PROPULSOR Russian patent published in 2014 - IPC B62D61/10 B62D61/00 

FIELD: transport.

SUBSTANCE: common bearing surface of wheeled propulsors for heavy military machines moving over loose ground and waterlogged foundations is made convex by sphere with radius of R_sph=D_sph/2=0.5l/sinψ, where D_sph - diameter of spherical surface, l - length of propulsor bearing surface, ψ - angle of propulsor bearing surface half-contact with foundation. Angle ψ=φ, where φ - angle of shear resistance of ground, peat of foundation with damaged structure at maximum in tensile strength pressure $$p_{str.G}^{tens}=2c\cdot \cos \phi /\left(1+{\sin }^2\phi \right)$$ - for ground, for peat - $$p_{str.P}^{tens}=2c\cdot \cos \phi /\left(1+\sin \phi \right),$$ where c=c_str(2-tgφ/tgφ_str), φ=arcsin[2sinφ_str/(1+sin²φ_str)]-φ_str, φ_str and c_str - angle of shear resistance and specific cohesion of foundation material sample of undamaged structure. Wheels are installed at each board of propulsor in two rows with longitudinal shift of rows for wheel radius.

EFFECT: higher cross-country ability of heavy vehicle wheeled propulsors over loose grounds and peat-bogs.
