A sensor for at least detecting steering torque of a steel steering column includes a magnetic field generating element which is configured to generate a magnetic field. The magnetic field penetrates the steering column so as to magnetize a steel material thereof. The sensor also includes a magnetic field detection element which is configured to detect a magnetic field change caused by a magnetoelastic effect of the magnetized steel material of the steering column when the steering column is subjected to torque stress. An output signal of the magnetic field detection element characterizes steering torque. The sensor also includes a base plate bearing the magnetic field generating element and the magnetic field detection element. The base plate is spaced from and separate from the steel steering column. The magnetic field generating element and the magnetic field detection element are directly mounted on the base plate.

Integrated torque and angle sensor for steering column monitoring with improved performance

A torque-angle sensor includes a torque sensing unit, an angle sensing unit, and a PCB. The torque sensing unit includes a signal input rotor and a signal output rotor. The angle sensing unit includes a driving gear and a driven gear that is fitted round and fixed to one of the signal rotors. The PCB has a torque magnetic field generating unit, an input shaft signal collecting unit, and an output shaft signal collecting unit that sense a rotation angle and torque of the signal rotors. The PCB has an angle magnetic field generating unit and an angle collecting unit that sense a rotation angle of the driving gear and the driven gear. The torque magnetic field generating unit, the input shaft signal collecting unit, the output shaft signal collecting unit, the angle magnetic field generating unit, and the angle collecting unit are configured as coils formed by printed circuits.

Torque-angle sensor for monitoring a steering situation of a vehicle

A torque-angle sensor is mounted on a steering column with a system casing and configured to detect a steering torque and angle of steering wheel steering of a vehicle. The torque-angle sensor includes a top cover, a torque sensing unit, an angle sensing unit, a PCB, a signal output terminal, and a sensor casing. The top cover includes a body, a first fitting part, and second fitting part. The first fitting part is a flange extending from the body towards the sensor casing, and fitted to the sensor casing. The second fitting part is a flange extending in a radial direction and/or axial direction of the body, and fitted to the system casing. In a radial direction of the body, a distance between the second fitting part and a center of the body is greater than a distance between the first fitting part and the center of the body.

A sensor housing for a wheel-sensor device for a vehicle includes a first receiving aperture, a second receiving aperture, a first rotational-speed sensor, a rotary transducer, and a second rotational-speed sensor. The first sensor is configured to be inserted into the first aperture, and the sensor housing with the inserted first sensor is configured to be mounted on the vehicle. The rotary transducer is configured to co-rotate with a vehicle wheel and to trigger a change in a first physical quantity. The second sensor is configured to be inserted adjacent to the first sensor in the first aperture or in the second aperture, and the sensor housing, with the inserted first and second sensors, is configured to be mounted on the vehicle. The rotary transducer co-rotating with the rotating wheel triggers the change in the first physical quantity and a change in a second physical quantity.

Sensor housing for a wheel sensor device, wheel sensor device and connecting component thereof

A device for the production of cable sensors that each have at least one sensor and a cable trimmed to a variably pre-definable length includes at least two processing units, and at least one conveying unit. The processing units are configured to load and cut a cable blank, and are further configured to sequentially convey the cable blank along a pre-defined motion track. At least one deflection unit is positioned between adjacent processing units. Each deflection unit includes at least one deflection element that is in contact with or is configured to contact the cable blank. A displacement unit is assigned to and is configured to modify a position of the deflection element in order to influence a length of the motion track of the cable blank so as to obtain variable lengths of cable.

Device and method for manufacturing cable sensors

A sensor unit for a vehicle includes a sensor circuit, a main part that supports the sensor circuit with at least one sensor contact, a connection cable, and a pot-shaped sleeve. The main part includes a sensor contact, a cable contact, and common contact support. The sensor contact is positioned on a first end of the contact support, and the cable contact is positioned on a second end of the contact support. The sensor contact is electrically connected to the at least one sensor contact via at least one sensor counter contact, and the cable contact is electrically connected to the connection cable via at least one cable contact. The sensor circuit is arranged on an end region of the contact support such that the sensor circuit is oriented in a predetermined detection direction. The detection direction is based on a bending angle of the end region relative to a longitudinal axis of the main part. The pot-shaped sleeve is fixed to the main part, and surrounds the sensor contact and the sensor circuit. The shape of the sleeve is adapted to the detection direction of the sensor circuit.

A sensor unit for a vehicle includes a sensor circuit that is electrically connected to a connection cable via a sensor contact-making-element, a cable contact-making element, and a coaxial contact-making element. The sensor contact-making element includes at least two sensor contacts, and the cable contact-making element includes at least two cable contacts. The coaxial contact-making element is positioned between the cable contact-making element and the sensor contact-making element and includes, at a cable end, a first inner contact point having at least two contacts and, at a sensor end, a second inner contact point having at least to mating contacts.

A sensor subassembly for a vehicle has at least one sensor unit arranged in a cap-shaped plastic part. The cap-shaped plastic part is carried by a retaining bush and seals off the retaining bush at one end. An associated device is configured to measure rotational movement of a wheel bearing. A resilient sealing and compensating element in pressed in between the-shaped plastic part and the retaining bush, in a first sealing area for sealing off a first leakage path, so that the cap-like plastic part, in conjunction with the sealing and compensating element, seals off the retaining bush tightly at one end.
