Structural representation of the present utility model when Fig. 2 is gearbox band power takeoff;
Wherein, 1- operating mechanisms, 2- boosters, 3- clutch control valves, 4- major-minor casees interlock valve, 5- sources of the gas, 6- vehicles Valve, 7- power takeoffs, 8- centre positions cylinder, 9- check valves.
Embodiment
With reference to specific embodiment and Figure of description the utility model is further explained explanation.
The gearbox matching booster of conventional belt major-minor case interlocking structure, during without power takeoff, source of the gas is through major-minor case all the way The gas outlet of interlock valve enters operating mechanism, and another road source of the gas enters booster through clutch control valve.During band power takeoff, all the way Source of the gas supplies vehicle valve, and gas outlet of the gas outlet of vehicle valve first through major-minor case interlock valve enters operating mechanism, and odd-side gearshift is not complete Into when major-minor case interlocking valve air gate have compressed gas, the second gas outlet of vehicle valve compressed gas supplies centre position cylinder and power takeoff; Another road source of the gas enters booster through clutch control valve.So power assisted gearshift device can weaken major-minor case interlock function, to odd-side Synchronizer brings potential safety hazard.
Referring to Fig. 1, when speed changer is without power takeoff, the utility model includes major-minor case interlock valve 4, major-minor case interlock valve 4 Provided with an air inlet and two gas outlets, air inlet connection source of the gas 5, the first gas outlet A of major-minor case interlock valve 4 passes through gas circuit Operating mechanism 1 is connected to, the second gas outlet B of major-minor case interlock valve 4 is connected to clutch control valve 3, clutch by gas circuit Control valve 3 is connected to booster 2 by gas circuit.
Operation principle:When odd-side gearshift is not completed, first gas outlet A of the source of the gas 5 through major-minor case interlock valve 4 enters manipulation machine Structure 1, hinders driver's gearshift, now the second gas outlet B of major-minor case interlock valve 4 is without compressed gas, and booster 2 does not work.Odd-side When gearshift is completed, source of the gas 5 enters booster 2, booster 2 through the gas outlet B of major-minor case interlock valve 4 second, clutch control valve 3 Work, now the first gas outlet A of major-minor case interlock valve 4 will not hinder driver to shift gears without compressed gas.
