Abstract

PURPOSE: To prevent generation of tooth beating sounds at the time of idling by detecting the neutral position of main transmission and releasing the engagement between the input gear of the auxiliary transmission and stepless speed change gear.
CONSTITUTION: A neutral detection circuit 13 of main transmission consists of an operating switch 14, a switch 15 closed at the time when the main transmission 3 is at the neutral position, a switch 16 closed at the time the clutch is connected, and a relay 17. On the other hand, a controlling device 18 comprises a vacuum tank 19, a solenoid valve 20 operatd by a neutral signal, a diaphragm device 21, and a ring 22 connected to the central part of an arm 24 operating the shift fork 23 of the auxiliary transmission by means of a pin 24a.
