Abstract
The utility model discloses a bidirectional automatic overrunning clutch comprising a driving gear, a driven gear meshed with the driving gear and a spline shaft, wherein the driven gear, two unidirectional ratchets and a gear are sleeved with the spline shaft; the two unidirectional ratchets are positioned on the two sides of the driven gear respectively; and the gear is positioned on one side, back to the ratchet, of one of the two unidirectional ratchets. The bidirectional automatic overrunning clutch is novel in design and simple in structure, has a bidirectional automatic clutch function, brings high efficiency and energy conservation to an electric vehicle, effectively protects an electromotor and a controller, brings great convenience for people and promotes scientific and technological development.
Description
Technical field
The utility model relates to a kind of overrunning clutch, relates in particular to a kind of two-way automatic overrunning clutch.
Background technique
Overrunning clutch is the basic part that occurs along with the development of electromechanical integrated product, and it is between prime mover and the working machine or the vitals of the transmission of power between machine intimate driving shaft and the driven shaft and separation function.It is the conversion that utilizes velocity variations or the sense of rotation of driving and driven part, has the voluntarily device of clutch function.General electric vehicle overrunning clutch does not have the function of two-way automatic clutch.
Summary of the invention
In order to address the above problem, the utility model provides a kind of two-way automatic overrunning clutch, can effectively solve the problem of above-mentioned prior art deficiency.
To achieve these goals, the technical solution adopted in the utility model is: a kind of two-way automatic overrunning clutch, comprise driving gear and the driven gear meshing with it, also comprise splined shaft, be arranged with driven gear, two single direction ratchet, gear on the described splined shaft; Two single direction ratchet lay respectively at the both sides of driven gear; Gear is positioned at wherein a single direction ratchet back to a side of ratchet.
As preferably, described splined shaft is provided with the steel ball that resets.
The utility model has the advantage of: modern design, simple in structure, have the function of two-way automatic clutch, bring energy-efficiently to electric motor car, effectively protect motor and controller, bring great convenience to people, promoted simultaneously scientific and technological development.
Description of drawings
Fig. 1 is split-type structural schematic diagram of the present utility model;
Fig. 2 is stereogram of the present utility model.
Among the figure: 1, driving gear; 2, driven gear; 3, splined shaft; 4, the steel ball that resets; 5, single direction ratchet; 6, gear.
Embodiment
Below in conjunction with the accompanying drawings and the specific embodiments the utility model is described in further detail.
Referring to Fig. 1, Fig. 2, a kind of two-way automatic overrunning clutch comprises driving gear 1 and the driven gear 2 meshing with it, also comprises splined shaft 3, is arranged with driven gear 2, two single direction ratchet 5, gear 6 on the described splined shaft 3; Two single direction ratchet 5 lay respectively at the both sides of driven gear 2; Gear 6 is positioned at that wherein a single direction ratchet 5 is back to a side of ratchet, and described splined shaft 3 is provided with the steel ball 4 that resets.
The utility model in use, when driving gear 1 clockwise rotates, driving gear 1 drives driven gear 2 and rotates counterclockwise, driven gear 2 can produce the single direction ratchet that moves axially be fixed on the close gear 6 on the splined shaft 35 automatic connection of rotatings of close gear 6 because of helical teeth, splined shaft 3 driven gears 6 rotate counterclockwise.When the rotating speed of gear 6 during greater than the rotating speed of driven gear 2, promote driven gears 2 near the single direction ratchet 5 of gear 6 and automatically separates with the single direction ratchet 5 near gear, the steel ball 4 that at this moment resets is in disengaged position with driven gear 2 location with two single direction ratchet 5 and makes it not send and contacts sound.When driving gear 1 rotates counterclockwise, driving gear 1 drives driven gear 2 and clockwise rotates, driven gear 2 can produce away from the moving axially and the single direction ratchet 5 automatic connection of rotatings away from gear 6 that are fixed on the splined shaft 3 of gear 6 because of helical teeth, and splined shaft 3 driven gears 6 clockwise rotate.When the rotating speed of gear 6 during greater than the rotating speed of driven gear 2, promote driven gears 2 away from the single direction ratchet 5 of gear 6 and automatically separate with the single direction ratchet 5 away from gear 6, the steel ball 4 that at this moment resets is located driven gear 2 to be in disengaged position with two single direction ratchet 5 and to make it not send and is contacted sound.
Claims (2)
