VEHICLE DRIVE WHEEL ACTIVE DRIVE Russian patent published in 2022 - IPC B60G11/18 

FIELD: transport machine building.

SUBSTANCE: invention relates to automotive industry. Active wheel drive of the vehicle includes a hollow hub with a blade, stops with channels, a control sensor of torque oscillations, gas-hydraulic accumulators. Blade is fixed on the drive axle of the wheel and forms two cavities, forward and backward stroke. Stops with channels connect the cavities of the hub with cavities of the gas-hydraulic accumulator. Torque oscillation control sensor is arranged on wheel drive axle shaft. Electronic signal from the sensor is transmitted to the electronic control unit and then to the electromagnetic coils mounted in the stop. Viscosity of the magnetic rheological fluid in the hub cavity is changed by means of coils. Hub cavities are connected via controlled adjustable throttles to gas-hydraulic accumulators. Cavity of the forward stroke hub is connected to two gas-hydraulic accumulators, and of the reverse stroke — to one. Gas-hydraulic accumulators have different rigidity and are made with possibility of interaction with electronic control unit.

EFFECT: increase in the operational capabilities of the vehicle is achieved by expanding the dynamic range.
