Description

Throttle motor structure equipped with locator

Technical field

The utility model relates to the control technology of E-Gas, specially a kind of throttle motor structure equipped with locator.

Background technique

E-Gas is actually throttle valve completely by motor control, and engine controller passes through the tune to throttle valve body It saves and influences engine torque.EGAS control system mainly (is refered in particular to grip on board a dredger, excavated by gas pedal Machine is all using diesel engine, and throttle is to control distributive value and be different from gasoline engine oil door and control air inflow.Driver's cabin throttle Knob size control diesel pump fuel delivery number, throttle is bigger, then diesel pump fuel delivery is big, then the amount of injection is big.), pedal Displacement sensor, ECU (electronic control unit), data/address bus, servo motor and throttle execution mechanism composition, when monitoring that throttle steps on Plate height and position (refering in particular to the variation of grip angle on board a dredger) changes, and pedal displacement sensor moment is by this information It is sent to ECU, ECU carries out calculation process to the data information that the information and other systems transmit, calculates a control signal, leads to Cross route and be sent to servo motor relay, servo motor drives throttle execution mechanism, data/address bus be then responsible for system ECU and Communication between other ECU.Traditional E-Gas structure generally uses electric brush type potentiometer, and traditional potentiometer accuracy is not It is good, and be kept in contact with resistance when brush movement and cause to wear, cause service life not grown.

Utility model content

The shortcomings that in order to overcome the prior art to refer to, the utility model provide a kind of oil equipped with locator of servo motor Door motor structure uses the working condition of new-type locator auxiliary monitoring throttle motor.

The scheme that the utility model is taken in order to solve the above problem is: the throttle motor structure equipped with locator, including oil Door motor, reduction gearbox and locator, the locator include casing and data connector, are equipped with magnetic induction module in the casing And shaft, the data connector connect the magnetic induction module by data line, the top of the shaft is equipped with a magnet, The magnetic induction module is fixed on the top of the magnet, and the magnetic induction module is equipped with magnetic induction sensor and accordingly Detection circuit module, the bottom of the casing is stretched out in the lower end of the shaft, and the bottom of the shaft is equipped with gear；Institute It states throttle motor and locator is installed on the reduction gearbox, the lower end of the shaft is protruded into the reduction gearbox, and is passed through The gear connects the output shaft of the throttle motor.Throttle motor (motor) is connected by gear, throttle motor drives shaft It rotates synchronously, when magnet rotation, the weak voltage of magnetic induction sensor output changes, so as to measure the center point magnetic The rotational angle of iron compares if this voltage is connected to amplifier and carries out AD acquisition using digital filtering and voltage, The revolving speed and angle variable quantity of magnet can be obtained by carrying out quantification treatment to it by the processing system in magnetic induction module.

The reduction gearbox is made of upper box and lower box, and the upper box and lower box are connected by screw to fixation, institute It states locator and is installed on the upper box upper surface, the throttle motor is installed on the lower surface of the lower box.

The gear is removably mounted to the bottom of the shaft by pin shaft, is convenient for changing maintenance.

The shaft is installed in the casing by bearing, and the circlip for connecting the bearing is equipped in the shaft； The circlip is set to the lower section of the magnet.

The top of the shaft is equipped with the counterbore for placing the magnet.

The line outlet for facilitating winding displacement is offered on the casing.

The distance between the magnet and the magnetic induction module are 2.0~5.0mm.

It is equipped with one layer of magnetic shielding cover around the casing, prevents the interference of external magnetic field.

The beneficial effects of the utility model are: the throttle motor structure installation volume equipped with locator of the design is small, knot Structure is novel, is measured based on electromagnetic induction principle, measures the magnetic flux change of shaft by magnetic induction sensor to determine throttle The position of motor and rotation speed change；Break the measurement method of traditional Weight and disk type and potentiometer type, improves measurement accuracy, reliability Good, service life can reach 4~6 years.
