Problems solved by technology

This results in a very time-consuming installation and removal of the double torsion coupling, because for example other components of the powertrain have to be removed in addition to the double torsion coupling, such as the drive and / or the shaft assembly with the gear set shaft Gearbox
It is particularly difficult to assemble such couplings, often due to the offset between the output shaft of the drive and the input shaft of the shaft-mounted gearbox, partly caused by the structure and partly by the bogie, on the drive and / or manufacturing tolerances on the gearbox resulting in

Embodiment Construction

[0064] exist figure 1 The double torsion coupling according to the invention shown in is essentially composed of two torsion couplings 20 and 30, so that each of the two torsion couplings 20, 30 forms a coupling of the double torsion coupling 1 device half. The two coupling halves or torsion couplings 20 and 30 are connected to one another via a two-part intermediate body 40 .

[0065] The first torsion coupling 20 itself has a first connecting flange 21 via which the torsion coupling can be connected to a torque-generating drive, for example an electric motor. The first connecting flange 21 is connected to one side of the first elastic connecting element 22 . To this end, the first elastic connecting element 22 is screwed to the first connecting flange by means of a plurality of fastening screws 24 arranged distributed around the circumference of the connecting element 22 . To this end, the fastening screws 24 are each guided through bearing bushes 27 which are pressed int...

Abstract

The invention relates to a double-torsional coupling (1) for connecting two shaft ends, in particularly for drive-side use in a rail vehicle, comprises a first torsional coupling (20), a second torsional coupling (30) and an intermediate piece (40) that connects the second torsional coupling (30) with the first torsional coupling (20). Here, the intermediate piece (40) consists of at least first and second portions (41, 42). First and second elastic connecting elements (22, 32) are embodied in each case as a one-piece flexible connecting disc. The invention further comprises a drive train with the double-torsional coupling, and a method for mounting the double-torsional coupling at a drive side arranged in a drive train of rail vehicle spring damping.

Description

technical field [0001] The invention relates to a doppel-torsion coupling for rail vehicles according to the preamble of claim 1 , a drive train with such a doppel coupling according to claim 6 And a method for assembling a double torsion coupling according to the preamble of claim 9 . Background technique [0002] Non-switchable elastic double torsion couplings lead, in addition to torque transmission from one shaft to the other, to axial, radial and angular misalignment at the ends of the two shafts to be connected to each other. Compensate for shifting. Vibration and sound insulation of the shafts to be connected to one another can also be achieved by means of such a double torsion coupling. Such double torsion couplings can be used, for example, in partially spring-damped drive trains of rail vehicles. Here, the drive, for example an electric motor, is suspended on a spring-loaded bogie, while the subsequent gearbox in the power flow is implemented as a shaft-mounted ...
