straight coupling in a drum brake

[Nettuno]

Good morning to all,

study mechanical engineering at the bari polytechnic and are already a user of the forum.
are at grip with the resolution of drum brakes, meaning "resolution", find the right of approach, the circle of breaks to arrive then to find the braking force and therefore the moment.
I would like to show you the design of a brake formed by two strains.
one is to rigid combination (the right one) and the other to free approach (the left one). I can't locate the center of instant rotation of the strain on the left, which would allow me, after connecting it with the center of the drum, to track the perpendicular and find the angle of approach.
Could you give me a few tips?

You got it? can you post the solution?

i'm very interested, too, but i'd like to understand the pattern.
is it a drum with floating or fixed jaws?

hi nettuno and well found!
I'm glad to hear about ours.
A hug.

I'm sorry for the oct

of the 2 strains, one is to rigid combination (the right one) and the other to free approach. I discovered that the free combination strains cannot be found a priori the instant rotation center precisely because the arrangement is free... So the question was wrong. the information that I have on such strain is the force of the hinge to, or rather, its direction that derives from the balance of forces acting on the lever that drives the brake.. .
