摘要： A transmission with a drive shaft (10), an output shaft (20) mounted coaxially thereto and a countershaft (30), there being provided a first constant gear pair (K1) that can transmit the rotation of the countershaft (30) to the output shaft (20) and wherein respective toothed gear pairs are allocated to the individual gears, the gear pairs optionally transmitting the rotation of the drive shaft (10) to the countershaft (30). A second constant gear pair (K2) can transmit the rotation of the countershaft (30) to the output shaft (20). The toothed gears (1-1, 1-2; 2-1, 2-2; 3-1, 3-2) of a gear of a first group of gears can be optionally select to be operative between the drive shaft (10) and the countershaft (30), the rotation of the countershaft (30) being transmissible via the first constant air (K1) to the output shaft (20). After switching to the second constant gear pair (K2), a gear of a second group of gears, via the second constant gear pair (K2) can be switched to the output shaft (20) by selecting a toothed gear pair (3-1, 3-2) of a gear of the first group and transmitting the rotation of the countershaft (30) via the second constant gear pair (K2).

摘要： A transmission 1 includes: a casing 2 and rotatable shafts 50, 60, 70. A drive gear of a reversing gear train 24 and a drive gear of a first speed gear train 25 are fixed on the input shaft 50. The gear change mechanism for 1st speed operation is constituted by he fixed 1st gear 25, a rotatable 1st gear 22, and a synchromesh device 20 supported on the intermediate shaft 60. The gear change mechanism for reversing operation is constituted by the fixed reversing gear 24, a rotatable reversing gear 21, and the synchromesh device 20. An idle gear 66 is rotatably supported on an idle shaft 65 that is supported by a wall of housing 511 adjacent to the reversing gear.

摘要： When in a change speed mode, the transmission has an input shaft that provides driving power to an axially aligned but separately rotatable output shaft through a countershaft assembly situated alongside the input shaft and containing a series of change speed gears. A special slider assembly located on the input shaft and the output shaft between the input and output gears is in meshing engagement with the output gear at this time to operably connect the output gear with the output shaft. When the slider assembly is shifted to its fully forward direct drive mode, however, the countershaft assembly is decoupled from the input shaft and the slider assembly serves to directly couple the input shaft with the output shaft. The slider assembly is comprised of two relatively rotatably parts, one comprising a slider sleeve that meshes with the output gear when the slider assembly is in its changed speed position and the other comprising a slider collar circumscribing the sleeve that is telescopically received within a socket in the hollow input gear. When the slider assembly is in its direct drive position, the slider collar is fully received within the profile of the input gear and thereby adds no additional length to the transmission.
