摘要： A brake effort monitor for railcar braking systems includes means connected to receive a brake effort request signal and a vehicle speed signal for generating an energy requested signal. Another device is connected to receive a brake effort actual signal and a vehicle speed signal for generating an actual energy signal. There is a mechanism connected to receive the energy requested signal and add it to one of a previous energy requested signal and a predetermined value for generating an energy requested sum signal. A device is connected to receive the actual energy signal and add it to one of a previous actual energy signal and a predetermined value for generating an actual energy sum signal. A comparator is connected to receive the energy requested sum signal and the actual energy sum signal for generating a performance comparison signal and a storage device is connected to receive at least one of an energy requested sum signal and an actual energy sum signal and a performance comparison signal for storing at least one signal.

摘要： By calculating energy used by friction brake equipment, the amount of friction brake shoe/pad wear is monitored. As amount of energy supplied reaches a percentage of the friction brake shoe/pad energy design limit, and indication for inspection is provided. If the supplied friction energy continues to increase the brake material must be replaced. The software logic limits are tunable for custom configuration by maintainace personnel. This invention measures amount of friction effort supplied with respect to time and distance in a software controller brake system and allows the software to determine when the friction brake material must be replaced on actual data and avoids costly damage from braking with worn out shoes/pads. This invention annunciates through the software when the friction material requires inspection and replacement and provides software logic to indicate remaining material thickness.
摘要翻译：通过计算由摩擦制动设备使用的能量，监测摩擦制动蹄/垫磨损量。由于能量供给量达到摩擦制动蹄/垫能量设计极限的百分比，因此提供了检查指示。如果供应的摩擦能量持续增加，制动材料必须更换。软件逻辑限制可由维护人员进行自定义配置。本发明测量在软件控制的制动系统中相对于时间和距离提供的摩擦力的量，并允许软件确定摩擦制动材料何时必须被替换为实际数据，并避免由于磨损的鞋/垫而产生昂贵的制动损坏。本发明通过软件通知摩擦材料需要检查和更换，并提供软件逻辑来指示剩余的材料厚度。

摘要： A disc brake caliper assembly for moving brake pads straddling the brake disc against each side of a brake disc comprises two tongs pivotably supported. The tongs have brake heads and pads at one end and power nut support pins journaled at the other end. The power nuts are pivotally supported from the power nut support pins. A power screw extends between the tongs and has external threaded ends threaded in the power nuts such that rotation of the power screw will force the power nuts apart thus causing the brake pads to engage the brake disc.
