PLAY ADJUSTMENT IN A HYDRAULIC BRAKING SYSTEM

摘要

An economical, light and reliable hydraulic braking system for braking a moving mass includes a pressure element or press part for pressing onto a brake surface under frictional contact, a brake actuator filled with hydraulic fluid for producing pressure in the pressure element and a spacing device for adjusting play between the pressure element and the brake surface when the brake system is in a released or non-active position. The spacing device includes a hydraulic accumulator for accumulating a predefined volume of hydraulic fluid at a minimum pressure. The hydraulic accumulator can be connected to the brake actuator, thus avoiding the use of mechanical stopping or blocking devices.
