Abstract: A braking gear having two turnable levers coupled by a spring and carrying brake shoes which engage the disk of the machine to be braked at both sides thereof and a double-acting hydraulic cylinder mechanically connected with the turnable levers by way of an articulation double-link members. The double-link member has a common articulation joint which is connected with the piston rod of the hydraulic cylinder. The ends of the articulation double-link member are connected with the levers and are acted upon by the spring, coupling the turnable levers, due to which the levers are reliably fixed both when the braking gear is switched on or off.
