Description
Technical field
The utility model belongs to the technical field that Injection Pump controls, in particular to a kind of pull bar return mechanism.
Background technique
Diesel engine, when normally working, carrys out moving left and right of regulating tie bar by electronic speed regulator drive motor shift fork parts, thus control Injection Pump fuel delivery number, regulate diesel engine state.But when diesel engine needs to shut down, electronic speed regulator is by power-off, and now pull bar often stops operating thereupon, if when pull bar is parked in non-oil-break position, Injection Pump cannot oil-break, and motor cannot be shut down in time.
Regulating tie bar return, makes Injection Pump be in oil-break position.Pull bar is a kind of transition apparatus connecting Injection Pump and electronic speed regulator.When diesel engine needs to shut down, just must by Injection Pump oil-break.Now just need to act on pull bar by regulating tie bar return mechanism, Injection Pump is in oil-break position.
Model utility content
The purpose of this utility model is that providing a kind of controls by pull bar the pull bar return mechanism that Injection Pump carries out automatic fuel cut-off after electronic speed regulator power-off.
The present invention is directed to the deficiencies in the prior art, a kind of pull bar return mechanism is provided, comprise electronic speed regulator, motor shift fork parts, pull bar and return elastic member, wherein, described motor shift fork parts comprise shift fork pawl, declutch shift shaft and shift fork bulb, described shift fork bulb and declutch shift shaft are separately fixed on shift fork pawl, described shift fork pawl is connected with pull bar, described shift fork bulb is arranged on electronic speed regulator revolvably, described return elastic member is arranged on motor shift fork parts rotatably), its elasticity is rotated along with electronic speed regulator drive motor shift fork parts and tightens up or loosen, described return elastic member, motor shift fork parts and electronic speed regulator are in same rotating center.
Further, described return elastic member is torsion spring, and the rotating center of described torsion spring is arranged on the rotating center of motor shift fork parts.
Further, described pull bar is also provided with the erection column matched with shift fork pawl, described erection column is vertically fixed on pull bar, and described shift fork pawl is connected on erection column.
Further, when Injection Pump is in oil-break state, the deposit moment of described return elastic member is in minimum state.
Further, when Injection Pump is in fuel feeding maximum rating, the deposit moment of described return elastic member is in maximum rating.
The beneficial effects of the utility model:
The utility model is rotated by torsion spring effect drive motor shift fork parts and forms rotary motion, consistent with electronic speed regulator (by stepper motor turning effort) working method and be in same rotating center, thus the contact reaching shift fork bulb and electronic speed regulator is more reasonable.Structure is simple, and facilitate attractive in appearance, return is effective.
