Chinese patent number: ZL97242519.5, name are called in the patent document of " electromagnetic actuator " and disclose a kind of electromagnetic actuator, and its electromagnet coil is that simplex winding coil, sensor are single rotary angle transmitter; Final controlling element beam warp synchronizing bar on the follower lever of position transducer assembly and the final controlling element body joins together, to reach the purpose that the straight line motion of armature is converted to the required rotation of rotary angle transmitter; The final controlling element axle is realized the no gap transmission between itself and pump rack by joiner.Its shortcoming is: the reliability of simplex winding coil and single-sensor work is low; The rotary angle transmitter poor linearity; Sensor elimination very close to each other mechanism; Movement conversion mechanism is complicated, has reduced speed of response, the control accuracy of device.In sum, its performance and reliability can not satisfy the requirement of high-pressure fuel pump of diesel engine to its drive unit.
Adopt the critical component of motor as diesel engine positioning control formula electronic speed regulation final controlling element; Obtained research; Like one Chinese patent application number be in 02243850.5 the patent document; A kind of straight line moving type electronic control dynamoelectric accelerograph final controlling element is proposed, two links, manual adjustment knob, manual/electric change-over switch mechanism, axial limiting body, the circuit for controlling motor that have housing, minisize dc reducing motor, reducing gear, be in transmission connection through screw thread.This structure function is complicated, adopts direct current generator as moving element, and reducing gear does not have backlash eliminator, and the screw thread transmission is difficult to guarantee precision.
One Chinese patent application number is in 200620113604.8 the patent document, to propose a kind of throttle actuator, and this final controlling element comprises: controller, data capture conditioning device, servocontroller and actuating motor.It is simple in structure that this final controlling element adopts actuating motor to have, good reliability, and advantage of high precision, but actuating motor does not have corner spacing firmly, does not have safety protection.
Torque motor is simple in structure, and output torque is big, can realize continuous stall; Technology maturation, weight and volume is little, and commercial Application is preferably arranged; With its main motor element, can realize the diesel engine speed control in the more high-power scope as diesel engine positioning control formula electronic speed regulation final controlling element.Can rotatablely moving of torque motor convert straight line motion into through ball guide screw nat.The friction of ball guide screw nat is little, speed is high, efficient is high.The straight line motion of axle is through the linear bearing transmission, and the friction of linear bearing is little, speed is high.
Summary of the invention
The purpose of the utility model is to provide the linear diesel engine speed regulating actuator based on torque motor that speed of response is fast, guarantee the reliable control of diesel engine speed.
The purpose of the utility model is achieved in that
