Abstract

本发明提出一种制动力与退距同时自动补偿的制动器补偿装置,这种装置包括一只补偿电动机和一只定位开关以及其它辅助的机械、电子器件。补偿电机的动作信号产生于定位开关,定位开关动作信号产生于制动弹簧的伸长(压弹)或缩短(拉簧)。补偿电机动动作的结果是使所述弹簧恢复到初始状态。也即:制动片磨损导致制动弹簧失去初始负载长度,弹簧失长后触动定位开关,定位开关使补偿电机转动迫使制动弹簧恢复初长。
The brake compensation device includes a compensating motor, a positioning switch and other auxiliary mechanical and electronic devices. The operation signal of the said compensating motor is produced by positioning switch, and the movement signal of the positioning switch is produced by extension or contraction of the brake spring, and the movement of the compensating motor can make the spring restore its initial state, i. e. the wear-and-tear of the brake pad can make the brake spring lose its initial load length, and the shortened spring touches the positioning switch, said positioning switch makes the compensating motor rotate to force the brake spring restore its initial length.
