Description

technical field

[0001] The invention relates to a sensor system for vehicle tires. The invention also relates to a vehicle tire, in particular a solid rubber tire, provided with such a sensor system. Background technique

[0002] WO 2018 / 077502 A1 discloses the practice of using sensor elements in solid rubber tires. The problem here is the connection between the individual sensor elements and the control unit (for example a microcontroller) assigned to the sensor elements.

[0003] This connection is typically via wires or metal conductor strips. However, especially in solid rubber tyres, these wires or metal conductor strips are exposed to strong deforming forces and thus may tear under long-term stress. It is especially important that the sensor element is not intended to be arranged in the region of the rim, and thus not in the vicinity of the control unit, but rather further outside in the tire.

Embodiment Construction

[0058] figure 1 A vehicle tire 1 is shown which is in the form of a solid rubber tire and is arranged on a rim 5 of a wheel system. The vehicle tire 1 has various elastomer layers. However, use in pneumatic tires is also conceivable. In a known manner, the elastomer layers form the bottom layer 4 with steel bars 6 , the intermediate layer 3 and the running layer 2 , each layer having different properties. In particular, the intermediate layer 3 is designed to be relatively elastic in order to minimize rolling resistance and thus reduce heat generation.

[0059] A vehicle tire 1 has in a hole (not shown) a sensor system 10 with a first sensor 11 and a second sensor 12 and a control unit 13 which in the illustrated embodiment is in the form of a microcontroller and arranged or Fastened in the region of the rim 5, for example in a molded-in recess.

[0060] The sensor 11 is arranged in the operating layer 2 and is in the form of a wear sensor. The area 27 of the sensor 11 fo...
