Embodiment Construction

[0022] The illustrated portal drive for a low-floor axle of a vehicle has a gear assembly arranged in a portal housing 4 driven by a differential 1 , the gear assembly has a drive wheel 2 with an intermediate wheel 3 meshes. The intermediate wheel 3 meshes with the driven wheel 23 .

[0023] For the differential 1 only the differential case 7 and the balance shaft 8 are shown, but the balance bevel gears arranged on the balance shaft 8 and the end of the drive shaft 5 facing the differential 1 are not shown drive bevel gear.

[0024] The drive wheel 2 with helical toothing is formed in one piece with the drive shaft 5 , which extends coaxially on one side towards the differential 1 , to form a drive wheel-shaft unit 6 . In this case, the drive shaft 5 protrudes into the door housing 4 through an opening 9 with a circular cross section of the door housing 4 toward the drive wheel 2 . In order that the drive wheel-shaft unit 6 can be inserted with its drive wheel 2 from one s...

Abstract

The invention relates to a portal drive, in particular to a portal drive for a low-floor axle of a vehicle, having a gear wheel arranged in a portal housing (4) driven by a differential (1) assembly, the gear assembly has a drive wheel (2) with helical teeth arranged on a drive shaft (5) rotatably driven by the differential, which meshes with the intermediate wheel (3) to drive the slave Drive wheel (23); opening (9) of the portal housing (4) through which the drive shaft (5) leads from the differential (1) to the drive wheel (2). The drive wheel and the drive shaft are integrally formed as a drive wheel-shaft unit (6), wherein the drive wheel-shaft unit (6) has an annular shoulder (22) on the differential side, the drive wheel-shaft unit utilizes The annular shoulder is axially supported on an annular stop fixedly fitted into an opening (9) of the portal axle housing (4) having a larger cross-section than the drive wheel (2).

Description

technical field [0001] The invention relates to a portal drive for a low-floor axle (Niederflurachse) of a vehicle, having a gear assembly arranged in a portal housing driven by a differential, the gear assembly having a gear assembly arranged to be rotatably drivable by the differential Helical-toothed drive wheel at the drive shaft, which meshes with the intermediate wheel to drive the driven wheel; opening in the door housing through which the drive shaft is led from the differential to the drive wheel. Background technique [0002] In such portal drives it is known that the drive shaft is designed as a splined shaft in the region of its end carrying the drive wheel. After the drive wheel has been installed in the portal housing, the drive shaft is passed through the opening of the portal housing and pushed onto the spline shaft with its coaxial spline sleeve contour and is fastened in this position on the spline shaft . Due to the splined shaft and the splined sleeve, ...
