Abstract:
1. A device for braking a moving mass, the device comprising: a brake lining; a braking surface; a movably guided coupling element for pressing said brake lining against said braking surface; a brake actuator having a brake cylinder, said brake actuator being filled with hydraulic fluid and connected to said coupling element for generating a pressing-on force to be applied through said coupling element to said brake lining; a pressure transducer to be attached to a frame of the mass to be braked, said pressure transducer having a supporting cylinder filled with hydraulic fluid and a supporting piston interacting with said supporting cylinder; a connecting device connected between said pressure transducer and said brake lining; hydraulic lines communicating between said supporting cylinder and said brake cylinder; and a regulating device setting a braking force as a function of a predefined setpoint value; said supporting cylinder is divided into a supporting chamber and a supporting return chamber by said supporting piston; said regulating device is configured to regulate a difference in pressure between hydraulic pressure in said supporting chamber and hydraulic pressure in said supporting return chamber; said regulating device including: a comparator for comparing a predefined setpoint value Δp said hydraulic lines including a fluidic high pressure circuit and a fluidic low pressure circuit communicating with said brake valve.
