Abstract

Un control del sistema de frenado requiere que se accione un primer sistema o sistema de frenado de servicio antes de que se pueda soltar un segundo sistema o sistema de frenado de estacionamiento para impedir movimientos inesperados. Un sensor detecta que los frenos de servicio esten embragados y controla un dispositivo para soltar los frenos de estacionamiento. Un sujetador asegura que los frenos de estacionamiento sigan sueltos. Por ejemplo, un piston y valvula de retencion forman el sensor y el sujetador. Contra el piston trabaja la presion de los frenos de servicio. Por encima de un nivel de umbral la presion de los frenos de servicio acciona el piston para abrir una valvula que proporciona aire a presion a un sistema para soltar el freno de estacionamiento. Una vez liberada, la valvula de retencion dirige la presion para soltar el freno de estacionamiento hacia el piston para mantener abierta la valvula.
