摘要： The invention concerns a partially sprung drive, in particular for electric traction vehicles, the partially sprung drive comprising a large gear which is mounted on the axle with an encasing gear housing. The partially sprung drive also comprises a small gear mounted in the gear housing. The coupled motor is secured rigidly to the bogie and the gear housing is secured to the bogie in a resiliently elastic manner by means of at least two resilient spring components which are mounted on the bogie such that they are approximately vertical and diametrically opposite the small gear shaft. The transverse line of action of the spring components passes through the centre of the small gear shaft. The object of the invention is to avoid the disadvantages of known drive housings suspended in an oscillating manner on the bogie side and externally of the pinion shaft. A further object is to attain a simple and overall satisfactory solution to the problem of securing the gear housing on the bogie, by means of which solution, in addition to economically minimizing the losses owing to deformation of the coupling, a stabilizing effect can also be achieved in order to save wear on the bearings. To this end, a defined radial pre-tension of the gear housing (3) relative to the wheelset (4/5) can be set via the transverse elasticity of the spring components (6). Advantageously the radial pre-tension can be set via an arrangement of rubber thrust springs with support surfaces above and below the gear housing (3).
