Abstract:
1. An electro-mechanical-brake (EMB) motor assembly comprising: a) an EMB electric motor including a drive shaft with a longitudinal axis; b) a parking-brake latch gear non-rotatably attached to the drive shaft and having a longitudinally extending gear tooth having a notch facing in a circumferential direction; c) a solenoid; and d) a spring operatively connected to the solenoid and having a spring projection which is longitudinally-deflectable against the parking-brake latch gear by energizing the solenoid and which thereafter is retainable in the notch of the gear tooth of the parking-brake latch gear by rotating the parking-brake latch gear to receive the longitudinally-deflected spring projection in the notch , wherein the spring has a substantially annular disk shape, wherein the spring is coaxially aligned with the drive shaft, wherein the spring projection is one of a plurality of substantially-identical spring projections of the spring, and wherein the gear tooth is one of a plurality of substantially-identical gear teeth of the parking-brake latch gear.
