Description
Technical field
The utility model relates to power take-off technical field, particularly relates to a kind of employing power take-off selector.
Background technique
The upper dress part with dedicated function has mainly been reequiped in the difference of special purpose vehicle and general-utility car, can complete some special transport and operation function.The upper dress part of most special purpose vehicle is all for power source with the motor of automobile chassis self, by power take-off actuation gear oil hydraulic pump, vacuum pump, plunger pump, light oil oil hydraulic pump, self-priming oil hydraulic pump, water pump, air compressor etc., thus for dumping car, refuelling truck, milk barrow, refuse collection vehicle, suction-type sewer scavenger, support the use with many special purpose vehicles such as car crane vehicle, high-altitude operation vehicle, bulk cement truck, breast board derrick cars.As can be seen here, power take-off seems particularly important in the Design and manufacture of special purpose vehicle.
Power take-off generally adopts automatically controlled gas to handle, and when driver opens the solenoid valve on the power take-off control switch connection chassis of setting in operator cabin, power take-off can be made to enter working state, and now pressurized air is by promoting the piston of power take-off cylinder, makes Power output; Otherwise driver makes power take-off quit work by closing power take-off control switch.At this, the usual very severe of the operating mode due to special purpose vehicle, very easily cause power take-off by mistake in running order because the control unit such as Vehicular vibration or solenoid valve lost efficacy, the personnel that cause injure and property loss.At present, the technological means solved this technical problem adopts two-way gas operation control system to control power take-off action, this kind of two-way gas operation control system comprises gas receiver, power take-off cylinder, the neutral gear position cylinder of cylinder cascade is kept off with transmission range, solenoid valve, air filtering regulator, power take-off control switch and neutral position switch, this power take-off control switch is arranged in operator cabin, its on off state is controlled by driver, when needs power take-off works, driver needs this power take-off control switch is closed, to export the power take-off enable signal being used for Controlling solenoid valve to gearbox controller, this neutral position switch is through the normal electricity of pull-up resistor access, the neutral gear position signal of Controlling solenoid valve is used for gearbox controller through neutral position switch output.Air outlet one branch road of gas receiver is communicated with the suction port of air filtering regulator, pressurized air through air filtering regulator filter and step-down after to the two H air valve air feed on transmission assembly, namely the air outlet of air filtering regulator is communicated with the suction port of two H air valve, another branch road is communicated with through the suction port of solenoid valve with neutral gear position cylinder, being pushed to cylinder piston transmission range being kept off cylinder by the cylinder piston of neutral gear position cylinder under the state connected at solenoid valve makes secondary box of gearbox be on the position of neutral, the suction port of this neutral gear position cylinder is communicated with the gas port of putting into gear of power take-off cylinder, by the pressurized air of non-step-down the cylinder piston of power take-off cylinder to be pushed to the state making power take-off be in put into gear power taking under the state connected at solenoid valve, the moving back of the high gear relief opening of above-mentioned pair of H air valve and power take-off cylinder is kept off gas port and is communicated with, and that thinks power take-off cylinder keeps off the chamber that gas port is communicated with and become the common pressure chamber of always usually pressing with moving back.The working principle of this kind of two-way gas operation control system is: when gearbox controller receives power take-off enable signal and neutral gear position signal, connect solenoid valve, the gas port of putting into gear of the suction port of neutral gear position cylinder and power take-off cylinder is made all to pass into the pressurized air of non-step-down, now, the cylinder piston of neutral gear position cylinder is pushed into and makes secondary box of gearbox be on the position of neutral, the cylinder piston of power take-off cylinder is pushed into state power take-off being in put into gear power taking, as speed-changing lever is now linked into the gear needed for low gear district by driver, namely power take-off enters working state, tooth cover stirred by drive shift fork by the cylinder piston of power take-off cylinder makes tooth cover input gear and hollow shaft are connected as a single entity, make Power output.
Because existing power take-off adopts automatically controlled gas to handle usually, therefore driver controls power take-off action by the power take-off control switch be arranged in operator cabin, so at present also not for the power take-off selector of power take-off configuration.
