<p>An actuator 102 and vehicle system (100, Figure 1) comprising a motor 204 coupled to a gear train 206. The gear train 206 having a drive gear 208 which has a first gear portion (234, Figure 4) and an integral drive nut portion (236, Figure 4). A drive screw 210 extends through the drive nut portion (236) and is moved linearly relative to drive gear 208 between two positions by action of the motor. The drive screw is coupled to a plunger 108 via at least one spring 806. Preferably an anti rotation feature (212, Figure 6) is attached to the drive screw 210, the anti rotation feature (212) extending into a slot in a housing 222 (Figure 7). A magnet (606, Figure 3) may be attached to the drive screw 210 and may interact with Hall Effect sensors (608, 610, Figure 3).</p> |
