INDEPENDENT SUSPENSION SYSTEM AND A CRANE THAT HAS SUCH SYSTEM Russian patent published in 2018 - IPC B60G21/05 B60G13/08 

FIELD: transport machinery.

SUBSTANCE: group of inventions refers to an independent suspension system. Crane contains a wheel-type chassis and wheels on both sides of each chassis bridge, connected to the frame by a suspension system. Each of the wheels on both sides of each bridge uses an independent suspension system. Independent suspension system contains two suspension hydraulic cylinders, a steering gear and two swing links arranged in accordance with the wheels on both sides. End on one side of each of the swinging links is pivotally connected with the wheel hub on the corresponding side with the help of a spherical hinge, and the end on the other side of each of the oscillating links is hingedly connected to a fastening member attached below the main speed reducer, using two spherical hinges, respectively, in the longitudinal direction. Each of the suspension hydraulic cylinders contains a piston and cylinder liner corresponding to each other, the protective covers of the inner layer and the outer layer. End of the extension of the piston rod of the suspension hydraulic cylinder is rigidly connected to the frame by means of a flanged end cap. Elastic damping pad is located between the end of the extension of the piston rod and the end cap of the flange type.

EFFECT: it is possible to avoid abrasive wear of the hydraulic cylinder caused by jumps in the up-down axis and angular impacts.
