SYSTEM OF AUTOMATIC TRANSMISSION CONTROL Russian patent published in 2009 - IPC F16H61/00 F16H63/00 

FIELD: machine building.

SUBSTANCE: invention is related to the field of motor transport machine building. System of automatic transmission control comprises pump, hydraulic distributor of modes having three positions, slide type pressure controller, hydraulic distributors of transmissions, pump filter, distributor filter, lubricating throttle, heat exchanger. In the first position hydraulic distributor of modes connects forward manifold and backward manifold to drain cavity. In the second position hydraulic distributor of modes connects forward manifold to the main manifold, and backward manifold to drain cavity. In the third position hydraulic distributor of modes connects forward manifold and backward manifold to the main manifold. Hydraulic distributors of transmissions are arranged as electromagnetic, and supply power fluid via control manifold to hydraulic cylinders of transmission control elements. Slide type pressure controller comprises stem with two pistons - left and right - that separate the stem into three sections. Pump filter is installed in supply channel between drain and controller drain channel. Distributor filter is installed in main manifold between pump and hydraulic distributor of modes. Lubricating throttle is installed in lubricating manifold, through which liquid is supplied to lubrication system. Heat exchanger is installed between lubricating system and lubricating throttle.

EFFECT: higher reliability of automatic transmission.
