摘要:
In the case of a vehicle transmission (2) with two counter shafts placed in a transmission housing (8) for the distribution of load, with one input shaft (4) and one main shaft (20) coaxially aligned with the input shaft (4), a gear (24) is placed in the area between the input shaft (4) and the main shaft (20). The gear (24) is secured by a bearing (26, 28) between the input shaft (4) and the main shaft (20) and secured radially by bearings between the two counter shafts. The bearing (26, 28) constitutes the exclusive axial bearing between the input shaft (4) and output shaft (20). The axial bearing comprises two axial effective roller bearings (26, 28) which lie on opposed sides of a projection (30) of the gear (24).

Multi-speed step-change transmission for commercial vehicles having an one input shaft, a main shaft placed in an axial extension, one countershaft parallel thereto and one intermediate shaft parallel to the two shafts for the reverse gear and the shafts have gear wheels forming the ratio steps of the transmission. The sum of the tip radii of the intermediate gear (3) for the reverse gear and of the main shaft gear (1) for the first gear is smaller than the axial separation (a) between the main shaft (5) and the intermediate shaft (6).

摘要:
A change-speed gearbox of a motor vehicle having a drive input and a drive output shaft which are mounted in a main chamber of a gearbox housing and by which a power flow can be transmitted by the selective actuation of clutches such that, parallel to the drive input and output shafts, an intermediate shaft with an intermediate gearwheel is arranged in an auxiliary chamber of the gearbox housing which communicates with the main chamber, so that when the shifting device is appropriately actuated, a power flow is directed from the drive input shaft, via the intermediate gearwheel of the intermediate shaft, to the drive output shaft to produce a reverse rotation direction of the drive output shaft. The auxiliary chamber, accommodating the intermediate shaft, has a bell-shaped longitudinal section with an oval cross-section.
摘要:
A bearing arrangement for an auxiliary drive output shaft (1), in particular for a PTO shaft (1) in a multi-speed transmission of a commercial vehicle. The auxiliary drive output shaft (1) is driven by an intermediate gear wheel (3) of the transmission and is supported by at least one bearing (7, 10) on the drive input side and a bearing (9) on the drive output side of the auxiliary drive output shaft (1). The bearing on the drive input side is at least one radial bearing (7, 10) and the bearing on the drive output side is a conical-roller bearing (9).

摘要:
A manual transmission having an input shaft whose rotation is transmitted to an output shaft by a selected set of gearwheel pairs, which include gearwheels that are positioned on common axes at an angle to one another. The gearwheel pairs each comprise at least one cone-shaped gearwheel. Rotational direction reversal of the output shaft can be produced, upon actuation of a clutch, by an intermediate wheel which is positioned to one side of the arrangement axes and which engages a mating gear located on the driving side and one located on the driven side. At least one of the mating gears is conical and the intermediate wheel is cylindrical and arranged relative to the mating gears such that a rotational axis of the intermediate wheel is parallel to the lines of contact with the mating gears. The rotational axes of the intermediate wheel and each mating gear intersecting at a common point.
