The explanation of the utility model embodiment is not used to herein to limit the protection scope of the utility model.
Please refer to Fig. 1,2, a kind of actuator assembly of diesel engine smart electronics speed-regulating system provided by the utility model, by
Control unit control, and connect with diesel engine 200, diesel engine 200 includes pump rack and oil pump, it is characterised in that：It includes
Actuator 10 and accelerator rod, the accelerator rod include connecting rod 11, rocker arm 12, and actuator 10 includes shell 13 and shell
Direct current generator 110, gear-box 111, output shaft 112, position sensor 113 and the feedback cam 114 in internal portion, direct current generator
110 are vertically installed above bottom, and gear-box 111 is fixed on the side of direct current generator 110, and output shaft 112 is pivot structure company
Logical to be mounted on 13 side of shell and 112 both ends of output shaft protrude from shell 13, feedback cam 114 is mounted on output shaft 112, position
It sets sensor 113 and is mounted on 114 top of feedback cam, rocker arm 12 is connect at least one end of output shaft 112, and connecting rod 11 connects
Rocker arm 12 and pump rack.
Shell 13 is towards being equipped with dial 115 and pointer 116, the pointer 116 outside the two sides at 112 both ends of output shaft
One end connect with rocker arm 12.
The output corner α of the actuator 10, the i.e. rotational angle of rocker arm 12 are 36 °.When rocker arm 12 is from the state of Fig. 1
When completely rotating counterclockwise 36 °, pointer 116 is the graduation position that 100 are turned to from 0 graduation position of dial 115.
Length, that is, L of the rocker arm 12 is：1.8 times of the effective travel b corresponding with the output corner of the actuator of connecting rod 11.
The effective travel b of connecting rod 11 is the effective travel of pump rack, is specially that the rocker arm 12 completely turns
