Abstract: In a device for the electrical connection of preferably ALS sensors in or on roller bearings of truck wheels, a seat casing is provided for the transfer of the ALS sensor's signals from one side of the bearing ring to the other, which seat casing is located between the bearing ring and, e.g., the shaft. It serves as signal conductor or it is equipped with conductors consisting of wires, flat band conductors, conductive layers, or the like. The connection to the ALS sensor or a plug ring with a connecting cord, occurs preferably by way of slip rings 10, to exclude all operational interference induced by a creeping motion in a circumferential direction of the otherwise fixed bearing ring. In addition, without conductors or a cord the bearing will be simpler to assemble.

Abstract: An electrical connection, preferably for ALS sensors incorporated in wheel bearings, is installed coaxially on the wheel bearing and its side surface. It is equipped, for example, with slip rings which operate in conjunction with the electrical contacts of the ALS sensor which is solidly attached to the wheel bearing. This simplifies the manufacture and handling of the wheel bearing during transportation and assembly. In particular, the risk of damage to the connecting cord is reduced during operation.

Abstract: A device for sealing and generating electrical pulses in a bearing assembly including fixed and rotating bearing rings especially a wheel bearing for motor vehicles. The device consists of a sealing section on the fixed bearing ring with an embedded pulse generator for detecting rotational movement and a sealing section on the rotating bearing ring having cells a certain distance apart from each other which activate the pulse generator. The fixed bearing ring (4, 19) rotates with respect to the sealing section (2) which is secured against rotation by way of a machine element (1, 24), which holds the fixed bearing ring (4, 19).
