Abstract
PURPOSE: To enable the actuation of a sub-transmission in accordance with the change of the rear-wheel load by connecting a load sensor to a subtransmission controlling mechanism.
CONSTITUTION: When a signal of "1" is given by a load sensor 21, the signal of "1" is supplied to the 1st operation circuit 28, while a signal of "0" to the 2nd operation circuit 29, and thereby the switch 28a of the 1st operation circuit 28 is turned on, while the switch 29a of the 2nd operation circuit 29 is not turned on and remains in the off state. Therefore, the 1st solenoid 30a of a solenoid mechanism 30 is made to operate to introduce the atmospheric pressure into a chamber A and the negative pressure into a chamber B, respectively, and a rod 16a is driven, whereby a sub- transmission is operated. In this way, the sub-transmission is actuated in accordance with wheel load change.
