Actually there is one new type of non-dragging brakes: and I'm to find out if it worth that additional money that it's asked for. It uses electrical mechanism for forced retracting of the pads. But still it's interesting: all the brakes in the world have this problem (air brakes certainly) and...
2BobM3: You just guessed what I’m doing right now! We calculated that we can not just put the strain gauges – the strain is about 0.5microstrains and nobody knows any type of sensor to measure such a strain: it’s just below the normal error of such a measurement. So the minimum strain that can...
Yeah, turning the wheel with a digital (so as to put different measurements in the memory) torque wrench was the very first idea and I will do so: but just to compare the results with a sensors. The problem is that I can detect that parasitic moment even with the wrench - but it will be just a...
Oohh. Thank you. I confused. But still I don’t know how I will measure the torque: the calliper is connected to the brake carrier by means of two bolts (or even sometimes 4) and where am I supposed to stick the sensor and what force will it measure… Here is the pic of the brake
Hm... I was thinking about it and think that in this case with a strain gauges near the mounting bolts I'll measure the torque not on the brake disc, but the torque on the wheel, cause all the forces from the road will be transmited to that strain gauge. I think maybe to put a strain gauge right...
Yeah, but still it's a problem to get information about the brake torque. E.g. I want to have a laptop in the cab that will show me the brake force (so as to measure a torque) in the real-time, during the driving... Actually most of the time (during the ride) the brake force should be 0 N, but...
Does anybody know a method of measuring parasitic drag in the disc brake (pneumatically operated)? It's a kind of parasitic torque that presents in all modern brakes. After applying the brake and when it's released there is still some local contact between the lining and the disc. But after a...
