HYDROPNEUMATIC HITCH SYSTEM

摘要

The invention relates to tractor mounted implements hitch systems.  Its purpose is to expand functional capacity of hitch system providing effective vibration damping of tractor aggregate with implement during transport. This is achieved by including throttle in hydraulic line between the hydraulic cylinders and directional control valve, which is connecting hydropneumatic accumulators to the system. In particular constructions of hydropneumatic hitch system the hydropneumatic accumulators have different volume and charging pressure. Hydropneumatic hitch system is recommended to use for vibration damping of the tractor aggregates with large mass implements.
