A steering wheel () for a motor vehicle includes a steering wheel module () supporting electrical/electronic subassemblies (). 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 () 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 () 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.

A connecting device includes first and second housing parts which are rotatable relative to one another and are coupled together to define a space therebetween. At least one flexible cable is provided in the space defined by the housing parts. Each cable includes first and second end sections which are configured to be rolled and unrolled in a spiral or helix on associated contact surfaces of the housing parts, respectively. The end sections normally extend in opposite directions from each other circumferentially around the housing parts so that a U-shaped turning area at which cable movement reverses is formed in the space defined by the housing parts. Magnetic areas are arranged on at least one of each cable, the first housing part, and the second housing part to cause the end sections of each cable to removably adhere to the respective contact surfaces of the housing parts.

Connecting device

A device for fastening a casing tube switch module to a casing tube of a steering wheel shaft when a steering wheel is mounted on the steering shaft. The device including a clamping element and a bearing. The clamping element is arranged coaxially between the casing tube and the switch module. The clamping element exerts a clamping force in a direction extending radially out from the steering shaft. The bearing rotationally decouples the steering wheel from the switch module. The bearing has a stator operable for transferring an axial motion of the steering wheel as the steering wheel is mounted on the steering shaft to the switch module such that the switch module moves axially with respect to the casing tube toward the clamping element and tensions the clamping element to apply the clamping force to fasten the switch module to the casing tube.

A steering column module for a motor vehicle includes functional units such as steering angle sensors and torque sensors adjacently arranged on a steering column. The functional units deliver respective output signals and requiring respective control signals. An electronics unit is connected with an onboard power supply of a motor vehicle for receiving power. The electronics unit is operable for processing the output signals of the functional units and operable for generating control signals for the functional units. A first one of the functional units is connected to the electronics unit via electrical plug-in connector parts with correspondingly arranged counter electrical plug-in connector parts situated on the electronics unit. A second one of the functional units is combined with the electronics unit to form an inseparable assembly.
