Abstract

Un aparato para detectar e indicar eléctricamente un desgaste del freno de un vehículo, con un servomotor del freno que posee un dispositivo interruptormontado a un bastidor del servomotor con un miembro de resorte que rodea parcialmetne unabarra servomotora y adaptado para entrar en contacto con unaseccion de gran diámetro de la barra servomotora cuando el desgaste del freno hace que la barra servomotora se desplace a una posicion límite para efectuarel servicio mecánico. En condiciones de funcionamiento normal, el miembro de resorte está separado de la seccion de diámetro pequeno de la barraservomotora. El dispositivo interruptor está montado a un primer extremo del miembro de resorte provisto con un primero y un segundocontacto eléctrico quese extienden y hacen contacto eléctrico con una placa de conduccion unida al segundo extremo del miembro de resorte siempre que la barra servomotora delfreno no se haya desplazado hasta el límite para efectuar el servicio mecánico.
