Summary: | The utility model relates to electronic control reversing speed change valves, in particular to a pilot type mechanical pressure regulating electronic control reversing speed change valve used for a bulldozer, namely a novel electronic control speed change valve which controls switch-on and switch-off of a pilot type solenoid valve through electric signals so as to control on-off of main speed change oil ways of clutches of various gears. The novel electronic control speed change valve comprises a pressure regulating valve, a snap back valve, a gear reversing valve and a direction reversing valve which are connected through a hydraulic pump, a pilot control oil way is connected with the gear reversing valve and the direction reversing valve, the pilot control oil way is provided with a gear pilot reversing valve and a direction pilot reversing valve, and an oil outlet of the pressure regulating valve is connected with the gear reversing valve and the direction reversing valve. As each gear is independently pr |
