Abstract
A differential lock and parking structure is provided for a dual power source driving speed reducer, that includes first and second shafts, a differential lock mechanism, and a parking mechanism. The first and second shafts are connected to dual power sources, respectively; the differential lock mechanism and the parking mechanism are provided at the tail ends of the first and second shafts; and the differential lock mechanism includes a movable chainring assembly, a fixed chainring assembly, and a fixed armature assembly. The parking mechanism includes a parking gear integrated with a fixed chainring, a pawl assembly, and a parking cam assembly that drives the pawl assembly to realize the conversion between parking-in and parking-out.
