AUTOMATIC DEVICE FOR REDUCTION OF VEHICLE TRANSMISSION STIFFNESS Russian patent published in 2020 - IPC B60K17/10 

FIELD: transport machine building.

SUBSTANCE: invention relates to automatic device for reduction of vehicle transmission stiffness. Automatic device for reduction of transmission rigidity includes planetary transmission, which reactive link is connected to oil pump drive gear, oil pump is connected to suction and pressure lines, planetary transmission by carrier shaft is connected with gearbox and driven by engine. In pressure main line two-stage controlled throttle is installed, to the input of which safety valve and control valve are connected, damping valve is connected in parallel to throttle, at that there is a hydraulic tank and pneumatic hydraulic accumulator. In the oil pump drive gear moving loads are installed. Device is also equipped with a controller for collecting operational information and rotation sensors, pressure sensors in the pressure main line, cargo position sensors. Cargo position regulator, adjustable throttle valve and controlled throttle control valve are connected with actuators.

EFFECT: higher efficiency and reliability of engine.
