Abstract (en)
[origin: WO2012123438A1] An inboard bearing drive assembly for a rail vehicle chassis comprises an electric traction motor and gear train (50) mounted in an axle hung casing (51) with integral axle bearings (32, 33). The primary suspension (81, 82) is mounted on the casing and preferably offset from the wheelset axle, with the casing being restrained in rotation by a reaction link (40), conveniently coupled to the chassis. One or both axle bearings may be lubricated from the gearbox oil reservoir, and deformation of the casing may be accommodated by dissimilar axle bearings, wherein only one provides an axial restraint.
