Title: Engine speed control device
Inventor: ARIGA MASAHIRO
IPC: F02D1/04
Filed: 1995-03-30
Abstract: PURPOSE: To prevent a cable from interfering with other parts at the time of controlling maximum engine speed by making a floating arm fixable/ releasable by an actuator together with a stopper in an engine speed control device connected to the load lever of a limit speed governor. CONSTITUTION: In the normal travel state of a tractor, an actuator 21 interlocked with an air suspension holds the tip 18b of a floating arm 18 between an elongated driving rod 21a and a stopper 22. At this time, when a relay lever 13 is rotated through a first cable 12 interlocked with an accelerator pedal, a load lever 17a is rotated through a second cable 14. When air pressure in the air suspension is lowered to lower the vehicle height, on the other hand, the driving rod 21a is put in contracting motion to make the arm 18 rotatable, and the pivot point 13c of the relay lever 13 is shifted by the rotation of the arm 18 so as to suppress the increase of engine speed caused by the depression of the accelerator pedal.
