Technical field
The utility model relates to the device systems of diesel engine, relates in particular to novel digital electronic governor actuator of diesel engine.
Background technique
Diesel engine needs the speed regulator that can stablize rotary speed of diesel engine, up to this point, overwhelming majority speed regulator remains mechanical governor, because the intrinsic shortcoming of mechanical governor, cause diesel engine oil consumption height, discharge amount of exhaust gas is big, present upgrading regeneration product as the mechanical governor energy-saving and emission-reducing, electronic speed regulator progressively grows up, present Digital Governor for Diesel Engine has three types: the positioning control formula, time-based control and " common rail system ", wherein the time-based control electronic speed regulator is called electronically controlled unit pump again, " common rail system " is a kind of senior electronic speed regulator, and general said Digital Governor for Diesel Engine mainly is meant positioning control formula electronic speed regulator; Positioning control formula electronic speed regulator is divided into 2 kinds of simulation controlling type electronic speed regulator and digital control type electronic speed regulators again, analog electronic speed regulator adopts proportion electro-magnet to drive, volume ratio is bigger, general as an independent equipment, by throttle line control Injection Pump, and original mechanical governor is not cancelled, and cost is also than higher, thereby only suitable relatively large occasions such as diesel generator; Digital Digital Governor for Diesel Engine is little because of its volume, can fully phase out advantages such as mechanical governor, cost are lower, can be used in any occasion that replaces the existing machinery speed regulator; The digital electronic speed regulator is made up of speed probe, E-Gas, ECU (Electrical Control Unit) (ECU) and final controlling element etc., and wherein the final controlling element of digital electronic speed regulator all is driven by stepper motors.And existing stepper motor driven final controlling element all adopts and the similar shifting fork mechanism of mechanical governor, and this structure has two shortcomings, the one, and the arm of force of shift fork is longer, and the moment of required stepper motor is bigger, so need the more powerful stepper motor of adapted; The 2nd, stepper motor rotates the angle of adjusting less (being 16 °～22 °) under this structural condition, and to accurately regulate the fuel injection quantity of oil pump, just must adopt the stepper motor driving circuit of bigger segmentation number, this makes that the volume ratio of electronic speed regulator control unit ECU is bigger, and price is higher.
The model utility content
The utility model adopts shifting fork mechanism at stepper motor driven final controlling element of the prior art, the shift fork arm of force is long, required stepper motor moment is big, adjust angle is little, can't accurately regulate oil pump fuel injection quantity, problem of ultra-high price, and a kind of economic, practical novel digital electronic governor actuator of diesel engine is provided.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
Novel digital electronic governor actuator of diesel engine, comprise frame, stepper motor and tooth bar supporting sleeve are installed on the described frame, on the output shaft of stepper motor gear is installed, gear is meshed with the tooth bar that slides at the tooth bar supporting sleeve, tooth bar one end has connecting pin and the connecting plate that links to each other with injection pump plunger positioning control tooth bar, and the tooth bar the other end is equipped with Returnning spring.Adopt gear ﹠ rack structure, make required stepper motor moment only be 1/4th of shifting fork mechanism, stepper motor rotates the angle of adjusting has then increased by 8 to 9 times, when stepper motor was worked, tooth bar promoted injection pump plunger positioning control tooth bar by connecting pin and connecting plate, thereby regulate the fuel injection quantity of Injection Pump, reach the purpose of adjusting rotary speed of diesel engine, and behind the fuel injection quantity of regulating Injection Pump, make tooth bar reset to original state by Returnning spring and get final product.
As preferably, described tooth bar and the cylindrical shape of tooth bar supporting sleeve.This structure helps accurately processing and installs.
As preferably, the modulus of described gear is 0.5, and the gear number of teeth is 20.This structure is convenient to adjust angle that stepper motor rotates to vantage point.
As preferably, the modulus 0.8 of described gear, the gear number of teeth is 14.The angle that this structure causes stepper motor to rotate is 115 °, thus fuel injection quantity that can the beat setting Injection Pump.
According to the technical solution of the utility model, modern design, simple and reliable for structure, the angle of adjusting the stepper motor rotation is big, can use the stepper motor of smaller power and the step motor drive chip of less segmentation number, cost is low, easy for installation, can directly drive Injection Pump position regulation tooth bar.
