SYSTEM FOR ADJUSTING CONTINUITY OF SWITCHING CATERPILLAR AND WHEELED VEHICLE TRANSMISSIONS Russian patent published in 2006 - IPC F16H61/06 B60W10/10 B60K31/00 

FIELD: caterpillar and wheeled vehicles furnished with automatic movement controlling and adjusting system.

SUBSTANCE: system for adjusting continuity of switching transmissions of caterpillar and wheeled vehicles equipped with automatic movement controlling system has internal combustion engine, oil tank, oil pump, electric magnets, slide valves, first friction device, transmission, second friction device, commutation unit, microprocessor control unit, and controlled throttle. Throttle is located in pressure pipeline between oil tank and friction devices and is electrically connected with output of commutation unit whose input is connected to output of microprocessor control unit. Outputs of commutation unit are connected through electric magnets to inputs of slide valves, whose outputs are connected to inputs of friction devices. Adjustment system is further equipped with vehicle movement sensor connected to wheel drive, engine crankshaft rotational speed sensor, device designed for sensing oil pressure in transmission hydraulic control system and connected to inputs of friction devices, device designed for sensing oil temperature in hydraulic system and located in pressure pipeline. Outputs of said sensors are connected to respective inputs of microprocessor control unit.

EFFECT: provision for impact-free switching of transmissions and reduced dynamic loading of transmissions during switching thereof.
