Abstract:
An electrically actuated parking brake system and actuator (102) therefor. The actuator (102) includes a motor (200) having a drive shaft, and a gear train coupled to the drive shaft, wherein the gear train provides at least one mechanical output from the actuator (102). The gear train may include a drive gear (202) coupled to the drive shaft, a driven gear (204) coupled to the drive gear (202), and a planetary gear set (206) coupled to the driven gear (204). Various configurations are provided for isolating actuator components for controlling audible noise, including sub-frame isolation configurations, motor isolation configurations, and gear train isolation configurations.
Abstract:
Aktuator (12, 100, 200), umfassend:einen Motor (202);einen Antriebsstrang, der mit dem Motor (202) verbunden ist,eine Antriebsspindel (114), die mit einer Antriebsmutter (126) verbunden ist und die bei In-Gang-Setzen des Motors (202) die Antriebsspindel (114) zwischen einer ersten und einer zweiten Endlage bewegt, undwenigstens einen Magneten (218) sowie wenigstens einen Magnetfeldsensor, dadurch gekennzeichnet,dass die Antriebsmutter (126) über eine erste und zweite Feder (128, 130) mit einem Kolben (122) verbunden ist,dass der Antriebsstrang ein Ausgangsgetriebe aufweist,das mit der Antriebsspindel (114) und einer Sensorantriebsspindel (214) verbunden ist,dass die Sensorantriebsspindel (214) mit dem Magneten (218) verbunden ist,dass die Sensorantriebsspindel (214) den Magneten (218) zwischen einer ersten und zweiten Endlage bewegt, unddass die erste und zweite Endlage des Magneten (218) axial der betreffenden Endlage der Antriebsmutter (126) entspricht, wobei der Magnetfeldsensor ein Ausgangssignal in Abhängigkeit der Lage des Magneten (218) liefert.
Abstract:
A fuel filler door actuator including a motor, a gear train coupled to the motor and to a latch arm, and a locking cam coupled to the gear train. The locking cam resists movement of the latch arm from an unlocked condition to a locked condition. A manual override cable is disclosed for manually moving the latch arm from the locked condition to an unlocked condition. A push-push mechanism is disclosed for allowing facile opening of a fuel filler door, and a quick connect/disconnect feature is disclosed for allowing facile assembly of the actuator to a fuel filler door housing.
