- EP 2 256 032 B1 provides a sensor unit for a spindle drive, which detects a relative movement; analogously, EP 1 832 851 A2 proposes a position transmitter which makes it possible to determine a position using magnets and magnetic sensors.
- general assemblies and measures for the area of torques and control and regulation circuits can also be found in DE 20 2006 005 695 U1 or EP 0 784 174 A2.
- the present invention relates to a track system with a spindle assembly in the railway sector with an integrated sensor according to the preamble of the independent claims.
- Generic spindles include an integral, endocorporeal sensor unit, as the applicant z. B. In DE 20 2020 103 194 Ul proposes. The disclosure of this document is fully claimed for the present invention. Due to the endocorporeal arrangement, sensor assemblies are protected from direct weathering and direct access/direct impact and can provide more reliable and long-term measured values for control and regulation systems. Surprisingly, there are no products in the market for spindle drives in the area of track-guided systems/railway systems that propose or explain sensor technology as described above as an innovative and useful assembly group - especially for track-guided traffic/track systems.
- a track system comprises a spindle assembly with at least one integrated sensor, the at least one sensor being integrated into the spindle assembly via an integral and endocorporeal sensor assembly in the closed interior of the spindle designed for loads in the ton range.
- 'endoskeleton' refers to the arrangement of the sensor assembly inside a body and 'integral' refers to the effective connection to the body itself: the sensor assembly is inserted into the body in such a way that the volume conditions and Volume properties of the body such as elastic deformation, volume conductivity, temperature, temperature gradient, etc. become detectable.
- the body is a spindle; Conductivities, acting forces and temperature can, for example, be detected in their amounts and gradients by the sensor assembly inserted in this way.
- the sensor assembly is thus specifically integrated into the spindle assembly.
- the sensor assembly is integrated in accordance with the teaching of this document in the operationally closed internal volume of a mechanical component of a spindle assembly; the outside tightly enclosing component excludes direct weathering and is designed in the alloy for continuous, long-lasting function, preferably for a function of 25 to 50 years, and thus offers a sensor assembly arranged on the inside the necessary, high-quality protection directly and without further housing or additional measures .
