Embodiment Construction

[0027] figure 1 show Figure 4 The cross-sectional view of the sliding bar 10 in , wherein the sliding bar 10 basically consists of a carbon brush piece 11 and a supporting profile 12 . The sliding bar 10 is fastened on a telescopic arm (not shown here) by means of support angles 13 and 14, so that in the sliding contact section A, overhead wires, also not shown, come into contact with the sliding contact surface 15 of the carbon brush element 11 for the transfer of electrical energy. Also formed in the underside 16 of the carbon brush part 11 is a longitudinal groove 17 into which the tubular profile 18 is inserted. The tube profile 18 is connected via connecting lines 19 to sensor devices in the sensor system of the motor vehicle, not shown here. When the tube profile 18 is opened or snapped off at the tube profile wall 20 , compressed air flows out of the tube profile 18 , whereby the sensor device causes the telescopic arm to lower with the sliding bar 10 and thus separ...

Abstract

The invention relates to a sensor element for a sensor device and a carbon collector having a sensor element, in particular for energy transfer from a contact wire to a vehicle, wherein the sensor element is formed from a fluid-sealed tube profile (18) which can be arranged in a longitudinal recess of a carbon collector, wherein there is at least one predetermined breaking point designed on the tube profile.

Description

technical field [0001] The invention relates to a sensor element for a sensor device, in particular a carbon brush element for energy transmission from an overhead line to a vehicle, and a carbon brush element with a sensor element, wherein the sensor element is formed by a fluid-tight tube profile, The tube profile can be arranged in a longitudinal groove of the carbon brush element. Background technique [0002] Carbon brush parts are often also used as so-called sliding blocks for energy transmission from overhead lines to vehicles, eg locomotives. Furthermore, in the event of severe wear or damage to the carbon brush elements, damage to overhead lines or overhead lines can result. Motor vehicles are therefore usually equipped with sensor devices which cause the sliding block with the carbon brush elements and the telescopic arm to lower when a defined wear limit of the carbon brush elements is exceeded or damage occurs on the carbon brush elements. The sensor device co...
