Abstract

The invention provides an engine speed regulating device which comprises a shifting fork, a pull rod, a rotating speed setting part, a speed regulating lever and a fixing frame, wherein the shifting fork is movably connected with the speed regulating lever; the shifting fork is provided with a ball head and an adjusting part; the ball head is hinged with the pull rod; the rotating speed setting part is movably connected with the fixing frame; the rotating speed setting part is provided with a rocker arm and a crank arm; the speed regulating lever comprises a first connecting part and a second connecting part; the first connecting part is connected with the adjusting part through a correction spring; the second connecting part is connected with the crank arm through a speed regulating spring; and the fixing frame is fixedly connected with the engine. The engine speed regulating device has full-range speed regulating and two-pole speed regulating functions, simple structure, fewer parts and small movement clearance, and the phenomenon of response lag of the speed regulating device can be eliminated; and due to multiple stamping parts, die castings and standard parts, the engine speed regulating device is convenient for mass production.

Description

【Technical field】 [0001] The invention relates to a speed governor, in particular to a speed regulating device of an engine. 【Background technique】 [0002] The existing speed regulating device of the engine is a centrifugal mechanical speed regulating device, which drives the shaft of the governor to rotate through gears, etc., and the governor is provided with a speed regulating fly block and a sliding sleeve. After the speed is set, under the action of centrifugal force, the flying block pushes the sliding sleeve to act on the speed control lever, and makes the rack of the fuel injection pump move to the side to reduce the fuel volume. Side movement, so as to realize the automatic adjustment of the fuel injection quantity of the engine. Yet the speed regulating device of existing engine has following shortcoming: [0003] 1. It is impossible to realize the functions of full speed regulation and bipolar speed regulation at the same time; [0004] 2. The functions of enr...
