Abstract
The invention discloses a diesel accelerator control mechanism. The diesel accelerator control mechanism is characterized in that one end of an accelerator rod is connected with an oil spraying pump accelerator and the other end is fixedly connected with a U-shaped connecting fork through a locking nut. A pin shaft is inserted in a pin hole at an opening end of the U-shaped connecting fork and a round hole of a pull rod shaft for connection and positioning. A groove is formed in the other end of the pull rod shaft; a pull rod is positioned in the groove; and the pull rod shaft and the pull rod are fixed by using a nut. A fixed bracket is mounted in middle of the pull rod shaft, is positioned through two pin holes and pins on the pull rod shaft, and is fixed with a machine body. The pull rod is downwards pushed clockwise, and the pull rod shaft upwards rotates clockwise to synchronously drive the U-shaped connecting fork and the accelerator rod to forwards move; and the oil spraying pump accelerator is opened widely to realize reverse control of downwards moving the pull rod and forwards moving the accelerator rod. The mechanism is arranged outside a diesel engine without being interfered with other parts. Through the connection between a connecting rod and the pin shaft, the mechanism is flexible in movement, easy to be disassembled and convenient for maintenance of other parts of an engine.
Description
Technical field
The invention belongs to engine accessory, be specifically related to a kind of control device of diesel engine throttle.
Background technique
Accelerator control mechanism is the apparatus system controlling engine operating state, and it belongs to the important appurtenances of motor.When Engine Matching car load, in the placement process of this control system, accelerator mechanism is as far as possible simple, smooth and easy.What require commercial car comfort level along with user at present improves constantly, the appurtenances of motor also get more and more, but the spatial volume of assembling motor is limited, so be subject to the impact of engine structure and arrangement spatial position, layout and the trend of accelerator mechanism are very large by the impact of diesel engine crawl space.General custom engine oil door handle pushes away forward as fueling state, but according to the layout of car load, now requires to pull back into refueling, and this just requires and a set ofly turns to accelerator mechanism to realize " oppositely " operation.The present invention just proposes to realize this function.
Goal of the invention
The object of this invention is to provide a kind of diesel engine throttle operating-controlling mechanism, to adapt to the requirement of engine whole vehicle layout, and it is smooth and easy to control power control flexibly, exactly by this mechanism.
Summary of the invention
That diesel engine throttle operating-controlling mechanism, comprises Injection Pump throttle, throttle lever, locknut, U-shaped clevis, bearing pin, pull rod shaft, pull bar, fixed support and bolt etc. for realizing this object the technology used in the present invention structure.One end of throttle lever is connected with Injection Pump throttle, and the other end is fixed in succession by locknut and U-shaped clevis.U-shaped clevis opening end is provided with pin-and-hole, and one end of pull rod shaft has circular hole, and the circular hole of pin-and-hole and pull rod shaft that bearing pin inserts U-shaped clevis opening end connects location.The other end of pull rod shaft is with groove, and pull bar is placed in the position of groove, pull rod shaft and pull bar is fixed with nut.In the middle of pull rod shaft, fixed support is housed, fixed support is by two pin-and-holes in the middle of pull rod shaft and pin location.Fixed support is fixed by two bolts and body.Pushing drawing rod under clockwise direction, makes pull rod shaft clockwise direction is rotated, and drives U-shaped clevis and throttle lever to travel forward simultaneously, Injection Pump throttle is left greatly, realizes pull bar and moves down and Reverse Turning Control that throttle lever is moved forward.
As the structural innovation of one, in the assembly space that motor is narrow, change current engine oil door handle and push away forward as refueling operation.The layout special according to motor, proposes this mechanism a set of and realizes " oppositely " operation, make it pull back as fueling state.
Feature of the present invention and beneficial effect are that accelerator control mechanism is arranged, so can not interfere with other parts according to the structure of diesel engine space outerpace.This structure mainly by connecting rod and pinned connection location, makes the motion of mechanism very flexibly and easily dismantles, also facilitating the maintenance of other parts of motor.
Accompanying drawing explanation
Shown accompanying drawing is stereochemical structure sketch of the present invention.
Embodiment
Structure of the present invention to be further described by embodiment below in conjunction with accompanying drawing.
Diesel engine throttle operating-controlling mechanism, its structure composition is: one end of throttle lever 2 is connected with Injection Pump throttle 1, and the other end is fixed in succession by locknut 3 and U-shaped clevis 4.U-shaped clevis opening end is provided with pin-and-hole, and one end of pull rod shaft 6 has circular hole, and the circular hole of pin-and-hole and pull rod shaft that bearing pin 5 inserts U-shaped clevis opening end connects location.The other end of pull rod shaft is with groove, and pull bar 7 is placed in the position of groove, pull rod shaft and pull bar is fixed with nut.In the middle of pull rod shaft, fixed support 8 is housed, fixed support is by two pin-and-holes 9 in the middle of pull rod shaft and pin location.Fixed support is fixed by two bolts 10 and body.Pushing drawing rod under clockwise direction, makes pull rod shaft clockwise direction is rotated, and drives U-shaped clevis and throttle lever to travel forward simultaneously, Injection Pump throttle is left greatly, realizes pull bar and moves down and Reverse Turning Control that throttle lever is moved forward.
Locknut is used to adjustment and the angle between fixing throttle lever and Injection Pump throttle.Pull rod shaft, pull bar, U-shaped clevis and throttle lever are all Hard link, with the position consistency of the position and Injection Pump accelerator open degree that ensure pull bar.
During assembling, locate with two plain washers after pull rod shaft penetrates fixed support, fixed by two cotter pins.The pull rod shaft the other end is connected with pull bar simultaneously, fixes with nut and spring washer.Throttle lever one end is that outside thread is connected with U-shaped clevis and fixes with locknut, and adjusts length that throttle lever stretches out and the angle with oil sprayer accelerator open degree, then uses nut-locking.Fixed support is fixed on diesel engine body by manipulating mechanism of oil throttle bolt.
The present invention is applied to engineering machinery type diesel engine and is matched with fork truck or tractor, and implementation result is good.
