Description
Technical field
It the utility model is related to a kind of diesel engine speed regulation mechanism.
Background technology
Governor lever is the main speed regulating structure of single cylinder diesel, existing speed control lever for single cylinder diesel engine, is by left and right
The biped body structure that two trailing arms are integrally cast via cylindric connector, it is additionally provided with and biped in the opposite side of cylindric connector
The shifting fork structure that body structural integrity is cast.Such a speed adjusting gear sensitivity is low, and cold start-up is difficult, and idling is high, and speed governing easily occurs not
Surely.Therefore, there is a kind of speed adjusting gear with secondary governor lever, between governor lever and secondary governor lever set extension spring and
Contact, still, this mode, which is started between the elastic force of extension spring and contact, a transfer process, causes engine performance to have interval not
Surely.
Utility model content
The utility model devises a kind of diesel engine speed regulation mechanism in view of the shortcomings of the prior art.
The utility model is realizes object above, using following scheme：A kind of diesel engine speed regulation mechanism, including speed governing thick stick
Bar, secondary governor lever and speed control rod, the governor lever include speed-regulating arm and shift fork, and the junction of the speed-regulating arm and shift fork is set
Have through hole, the speed control rod passes through the through hole, and the secondary governor lever is fixedly connected on the speed control rod, the shift fork and
Secondary governor lever is provided with corresponding contact, and the secondary governor lever is provided with limited post, the shift fork be provided with it is described
The shrinkage pool that limited post coordinates, spring is socketed with the limited post, one end of the spring with the secondary governor lever with fixing
Connection, its other end are fixedly connected with the bottom surface of the shrinkage pool.
Further, the shift fork is provided with reinforcement.
Further, the wall thickness of the secondary governor lever is 3.2mm.
Further, the secondary governor lever is provided with reinforcement.
Compared to the prior art the utility model, has the following advantages that and beneficial effect：Governor lever and secondary governor lever
Between spring by limited post defined position, prevent spring offset from deforming；Contact is separatedly installed with spring, avoids engine
Performance is intermittent unstable.
Brief description of the drawings
Fig. 1 is the utility model structure diagram；
Fig. 2 is Fig. 1 A-A views.
Embodiment
With reference to Fig. 1 and Fig. 2, a kind of diesel engine speed regulation mechanism, including governor lever 1, secondary governor lever 2 and speed control rod 3, institute
Stating governor lever 1 includes speed-regulating arm 11 and shift fork 12, and the junction of the speed-regulating arm 11 and shift fork 12 is provided with through hole 13, the tune
Fast bar 3 passes through the through hole 13, and the secondary governor lever 2 is fixedly connected on the speed control rod 3, the shift fork 12 and secondary speed governing
Lever 2 is provided with corresponding contact 41,42, and the contact 41 wherein on shift fork 12 is handled by high-frequency quenching, to improve hardness,
The secondary governor lever 2 is provided with limited post 21, and the shift fork 12 is provided with the shrinkage pool 14 coordinated with the limited post, the limit
Position post 21 on be socketed with spring 5, one end of the spring 5 is fixedly connected with the secondary governor lever 2, its other end with it is described
The bottom surface of shrinkage pool 14 is fixedly connected.The shift fork 12 is provided with reinforcement.The wall thickness of the secondary governor lever 2 is 3.2mm.It is described
Secondary governor lever 2 is provided with reinforcement.
In diesel engine starting, the thrust acted on speed-regulating arm 11 is small, is not enough to overcome the elastic force for starting extension spring, now
Starting oil mass is larger, diesel engine is smoothly started in a short time.When diesel engine reaches normal thermodynamic state, subtract throttle drop
Rotating speed, when the contact on the contact of secondary governor lever 2 and shift fork 12, injection pump fuel delivery is stable to be fixed, and diesel engine turns
Speed reaches minimum stable engine speed.
Described above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of the utility model technical principle is not departed from, some improvement and modification can also be made, these change
Enter and also should be regarded as the scope of protection of the utility model with modification.
