Abstract
An elevator brake regulating apparatus includes brake actuators, a source of pressured fluid and a brake regulating control connected between the actuators and the fluid source. A fastening housing is attached to a carrier frame of a elevator car and has recesses for retaining guides of a brake shoe with elastic pads to provide vertical displacement of the guides under braking. The brake shoe has brake pads for engaging running surfaces of a guide rail. A brake sensor in each brake pad monitors the condition of the brake pad and signals the control to apply pressured fluid to actuate the corresponding brake actuator. Other sensors for speed, acceleration and retardation of the elevator car are connected to the control for selectively applied the pressured fluid to regulate the braking force on the elevator car.
