Abstract:
1. A dual electric driving device, comprising: a main driving motor including a driving rotary shaft, and the main driving motor having an upper side and a lower side, a front end of the driving rotary shaft extending downward toward the lower side of the main driving motor and a back end of the driving rotary shaft extending upward toward the upper side of the main driving motor, with a steering gear being mounted on the front end of the driving rotary shaft; an outputting module being correspondingly mounted on the steering gear, the outputting module including a shifting driving shaft being rotatable by a driving force of the steering gear; a clutching and speed reducing driving device being correspondingly sleeved partially onto the back end of the driving rotary shaft of the main driving motor and coaxially rotatable by being engaged with the driving rotary shaft in only one single direction; and an accessory driving motor including a driving shaft, the driving shaft being correspondingly mounted partially through the clutching and speed reducing driving device, and further being able to push the driving rotary shaft in only one single direction to rotate by driving the clutching and speed reducing driving device; wherein the clutching and speed reducing driving device comprises an outer housing, an inner housing, a speed reducing gear train, and a single direction clutching bearing; wherein the outer housing is a hollowing housing with openings on two ends, and an inner gear ring is disposed on the middle portion of the inner ring surface of the outer housing, a plurality of cog structures are disposed on the inner ring surface of the inner gear ring; the inner housing is a housing with hollowing inner and circular outer ring surface, and mounted through the outer housing corresponding the cog structure and correspondingly rotates inside the outer housing, a plurality of openings are located on a periphery of the circular outer ring surface of the inner housing, and the inner housing extends downward to form an attaching frame, a clutching chamber is in the inward concave of the attaching frame; wherein the speed reducing gear train is correspondingly mounted in the hollowing inner of the inner housing, comprising a central gear and a plurality of speed reducing gears, the central gear is correspondingly mounted in the center of the inner housing, a number of the speed reducing gears corresponds to a number of the openings, and the speed reducing gears are correspondingly disposed around a periphery of the central gear and fits to the central gear with each other, each of the speed reducing gears has a disposed location, and each of the disposed locations respectively corresponds to one of the openings, each of the speed reducing gear locally mounts through the openings and fits to the cog structure; wherein the single direction clutching bearing is correspondingly mounted in the clutching chamber, an outer ring of the single direction clutching bearing is coaxially rotatable with the inner housing, and an inner ring of the single direction clutching bearing is correspondingly mounted on the back end of the driving rotary shaft; and wherein the driving rotary shaft correspondingly mounts through both the inner housing and the central gear and is coaxially rotatable with the central gear by being engaged.
