Abstract
PURPOSE: To prevent false operation in case of speed change, by continually letting the neutral lock action of a double engagement preventive mechanism precede to the shift action of a range-shift type transmission, in a shift controller for the transmission.
CONSTITUTION: When changing over car speed to a low-speed from a high-speed by operating a knob 61 of a transmission change-over mechanism 18 at a location shown in the figure, a neutral detector 19 is closed because a speed change lever is positioned at a shift location, and a low-speed shift valve 15 does not act. A lock valve 12 is operated to feed air to a neutral fixing device 11, and shift bars 72W74 are fixed to a cover 77 with the motion of a neutral location of the speed change lever. The neutral detector 19 is simultaneously closed and the low-speed shift valve 15 functions, air is sent to the low-speed side 37 of an operating cylinder 32 from a tank 30 and a shift fork 39 moves to the low-speed side. This motion is detected at a contact 48, and the lock valve 12 is released - that is, the shift bars can be operated by means of the speed change lever.
