SUSPENSION OF ROAD ROLLERS OF VEHICLE Russian patent published in 2021 - IPC B60G11/18 B62D55/00 

FIELD: transport means.

SUBSTANCE: invention relates to the suspension of road wheels of vehicles. The suspension of the road rollers of the vehicle includes a supporting road roller, a balancer, a hydraulic damper, and a second hydraulic damper. A vane piston with nozzles is installed in the cylindrical housing of the damper, rigidly connected to the balancer. The balancer, together with stops rigidly fixed inside the cylindrical body, divides the damper into two cavities filled with a magnetic rheological fluid. The stops are equipped with electromagnetic coils connected to an electronic control unit. The unit receives a signal from vibration sensors installed on the vehicle frame. The cylindrical body of the second damper contains a piston with a rod and nozzles. In the upper part of the piston there is a cavity connected by channels with the cavities of the first hydraulic damper. The lower part of the piston is spring-loaded with Belleville spring packages of various stiffness and is mounted on its rod. The vane piston is mounted on a hydraulic damper shaft connected to the balancer.

EFFECT: reduction of dimensions, which makes it possible to reduce dynamic and resonant loads on springs, and this leads to an increase in the travel of the road wheels, durability and an increase in the smoothness of the course in the event of vertical vibrations of the transport.
