Abstract
An actuator for an automated transmission in a motor vehicle drive train has a central actuating shaft with a shift finger. Two sleeves are supported concentrically on the actuating shaft and can be driven in mutually independent rotation. Two grooves of opposite helical pitch are arranged on the actuating shaft, and each of the sleeves has at least one inward-directed guide pin engaging one of the grooves.
Claims6
An actuator for an automated transmission in a motor vehicle drive train, comprising:
- a central actuating shaft with a shift finger;
- two sleeves supported substantially concentrically on the actuating shaft and arranged to be driven in mutually independent rotation about the actuating shaft, wherein two grooves of opposite helical pitch are arranged on the actuating shaft and each of the sleeves has at least one inward-directed guide pin engaging one of the groove, the guide pin being an integral part of the sleeve and thus securely attached thereto;
- two motors driving the independent rotation of the two sleeves, each of the two sleeves being driven by one of the two motors;
- and
- two reduction gear mechanisms, each of the two gear mechanisms being interposed between one of the two sleeves and one of the two motors.
