Abstract

A steering wheel (13) for a motor vehicle includes a steering wheel module (1) supporting electrical/electronic subassemblies (18). The steering wheel module is inserted from a front side of the steering wheel into a center of the steering wheel in order to be attached to the steering wheel. A lower end of the steering wheel module forms a torsion module (8) of a torque detection device for a steering power-assist system. The torsion module is operable to receive and be attached to a steering spindle (14) of a steering column on the back side of the steering wheel in order to attach the steering wheel to the steering spindle when the steering wheel module is attached to the steering wheel.
