摘要 |
A vehicle gearbox includes a basic gearbox with a main shaft that is an input shaft to a high-low range gearset joined to the basic gearbox. The basic gearbox has a control shaft, which, rotated in either direction from a neutral position, engages a selected gear. The control shaft is coordinated with a lock-out device which is controlled by a first sensor, which senses the speed of the output shaft from the range gearbox, and a second sensor which senses the engaged range in the range gearbox. An operating device holds the lock-out device in a lock-out position which prevents rotation of the control shaft towards the position for the lowest synchronized gear in the basic box, when the vehicle speed exceeds a predetermined speed in the low range of the gearbox. |
