Title:
【発明の名称】自動変速機における補助出力駆動部の制御方法
Document Type and Number:
Japanese Patent JP2001513730
Kind Code:
A
Abstract:
PCT No. PCT/EP98/01110 Sec. 371 Date Jul. 8, 1999 Sec. 102(e) Date Jul. 8, 1999 PCT Filed Feb. 27, 1998 PCT Pub. No. WO98/39172 PCT Pub. Date Sep. 11, 1998The invention related to a method for engaging power take-offs (28) in automated or partially automated transmissions (6) of commercial vehicles. A signal from the driver corresponding to a wish to engage the power take-off (28) is converted in a control device (34) into a signal for opening an automated clutch (4) between a prime mover (2) and the transmission (6) of the commercial vehicle. Once a predetermined minimum number of revolutions of the input shaft (10) of the transmission (6) is reached, a shifting device (26) is controlled for connecting the power take-off (28) with one transmission shaft (16, 42) that drives the power take-off (28) in order to obtain a closing of said shifting device (26, 52). The clutch (4) is again closed to prevent the teeth (50, 53) of the shifting device (26, 52) from remaining in front of each other. Sensors (32, 36, 40) determine whether the shifting device (26, 52) of the power take-off (28) has fully shifted, whether there is in the power take-off (28) a difference in the number of revolutions between the driving transmission shaft (16, 42) and the driven shaft (30, 72), or whether in the clutch (4) a defined adjustment travel has been exceeded.
