Brief description of the drawings
Fig. 1 is system architecture schematic diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, the utility model is described further.
Be illustrated in figure 1 the structure principle chart of the utility model for the motor auxiliary starting system embodiment of idling start and stop, as seen from the figure, this system comprises the two-way engaging clutch 2 connecting on the output shaft of motor 1, this two-way joint clutch appliance has three power connecting ends, the first power connecting end is for being connected with the output shaft of motor, and the second power connecting end is connected with an accumulated energy flywheel mechanism.
The two-way engaging clutch of the present embodiment is made up of active part 21 (i.e. the first power connecting end), the first secondary part 22 (i.e. the second power connecting end), the second secondary part 23 (i.e. the 3rd power connecting end), hold-down mechanism, operating mechanism (not shown) five parts.Between active part 21 and the first secondary part, 22 and first respectively have a mating face between secondary part 22 and the second secondary part 23, and wherein A is mating face 1, and B is mating face 2; Active part 21 is connected with the output shaft (being flywheel) of motor; The first secondary part 22 is connected with accumulated energy flywheel mechanism; The second secondary part 23 is connected with gearbox input shaft 3.
Two-way engaging clutch 2 has four kinds of working staties, is respectively: mating face 1 engages, and mating face 2 separates; Mating face 1 engages, and mating face 2 engages; Mating face 1 separates, and mating face 2 engages; Mating face 1 separates, and mating face 2 separates.
