The invention discloses an
independent suspension system for a super-heavy
chassis. The
independent suspension system for the super-heavy
chassis comprises upper cross arm assemblies, lower cross arm assemblies and hydro-pneumatic springs, wherein the upper cross arm assemblies, the lower cross arm assemblies and the hydro-pneumatic springs are symmetrically arranged at the two ends of an axle. One end of each upper cross arm
assembly is connected with a swing arm support of a
vehicle frame through a first bearing structure. One end of each lower cross arm
assembly is connected with the swing arm support of the
vehicle frame through a second bearing structure. The other end of each upper cross arm
assembly is connected with the upper end of a steering
knuckle through a first spherical hinge device. The other end of each lower cross arm assembly is connected with the lower end of the steering
knuckle through a second spherical hinge device. A supporting lug at the upper end of each hydro-pneumatic spring is connected with a hydro-pneumatic spring support on the
vehicle frame through a first
knuckle bearing structure. A supporting lug at the lower end of each hydro-pneumatic spring is connected with the corresponding lower cross arm assembly through a second knuckle bearing structure. The
independent suspension system for the super-heavy
chassis has the characteristics of being compact in structure, reasonable in arrangement, high in reliability and easy to maintain; and a super-heavy vehicle adopting the independent suspension system has good motor driving performance and rapid passing capacity.
