Problems solved by technology

[0009] Manufacturing splines is usually significantly more expensive than producing a cylindrical surface of sufficient quality for a press-fit joint
[0010] Implementation of the shaft / hub joint by welding - followed by a press-fit operation in assembly - may require significantly higher expenditure in terms of effort and cost than producing a cylindrical surface of sufficient quality

Embodiment Construction

[0055] exist figure 1 , a first embodiment of the shaft arrangement is shown schematically in longitudinal section and is indicated generally by the reference numeral 10 .

[0056] The shaft arrangement 10 has a shaft 12 which may be a solid shaft or a hollow shaft. The shaft arrangement 10 also includes a fixed gear arrangement 14 .

[0057] The fixed gear arrangement 14 has a first fixed gear 16 which has a first fixed gear tooth system 18 on the outer circumference. The first fixed gear wheel 16 also has a first axial side 20 and a second axial side 22 .

[0058] The fixed gear arrangement 14 also comprises a hollow shaft section 24 which extends in the axial direction from the first axial side 20 of the first fixed gear 16 . Preferably, the axial length of the hollow shaft section 24 is at least as long as the axial length of the first fixed gear wheel 16 and preferably less than four times the axial length of the fixed gear wheel 16 . A hollow shaft end of the hollow ...

Abstract

A shaft devcice (10) for a transmission (64) is disclosed, and is provided with a shaft (12) and a fixed gear unit (14). The fixed gear unit (14) is fixed on the shaft (12) through a shaft/hub joint part (30) and is provided with a fixed gear (16) and a hollow shaft portion (24), wherein the fixed gear (16) has a first axial side (20), a second axial side (22) and a tooth system (18), and the hollow shaft portion (24) surrounds the shaft (12) and extends from said first axial side (20) of the fixed gear (16). In the device, the shaft/hub joint part (30) comprises a main connecting portion (32), and the main connecting portion (32) is separated from the second axial side (22) of the fixed gear (16) in an axial direction.

Description

technical field [0001] The invention relates to a shaft arrangement for a transmission with a shaft and with a fixed gear arrangement fixed on the shaft via a shaft / hub joint and with a fixed gear and a hollow shaft section, wherein the fixed The gear has a first axial side, a second axial side and a tooth system, wherein a hollow shaft section surrounds the shaft and extends from the first axial side of the fixed gear. [0002] The invention also relates to a vehicle transmission having a shaft and having at least one fixed gear fixed to the shaft, said at least one fixed gear being connected in a rotatable manner in order to establish a gear stage of the vehicle transmission Movable gears mounted on additional shafts mesh. Background technique [0003] It is known practice in the transmission section of a vehicle to establish transmission stages by means of gear sets comprising loose and fixed gears. In this arrangement, the loose gear can be connected to or disconnected...
