Abstract
A rail vehicle bogey includes a transverse chassis (1) carrying the body of the vehicle. Indepently motorized wheels are connected to the chassis via resilient hinges (6) including a pivotable hinge arm which supports a traction motor (20) for independently motorizing each bogey wheel. Each arm supports the traction motor by a cradle defined by two branches of the hinge arm forming a fork and interconnected at one end by a spacer. One fork of each arm constitutes a transmission housing between the motor (20) and a wheel (4), whose axis is offset with respect to the axis of the corresponding independently motorized wheel (4).
