Abstract
The invention discloses an energy-saving bidirectional clutch, and belongs to the technical field of transmission, especially the field of electric automobiles. The energy-saving bidirectional clutch comprises an inner spiral spline sleeve, an outer spiral spline shaft, driving ratchets, a driven ratchet and a friction spring. The inner spiral spline sleeve penetrates the middle of the driven ratchet, the two driving ratchets are pressed on the two ends of the inner spiral spline sleeve in an interference fit manner, then the friction spring is arranged on the inner side of the advancing driving ratchet, and finally the outer spiral spline shaft is screwed in the inner spiral spline sleeve. The bidirectional clutch function and common overrunning clutch function can be achieved.
Description
Technical field
The present invention relates to technical field of automobile transmission, particularly a kind of device be separated with wheel by live axle, also can be applicable to other transmission fields, and achieves the function surmounting common clutch.
Background technique
Existing electric vehicle is that motor drives, in the process travelled, when unclamping accelerator, motor shuts down, but vehicle body can continue to move ahead due to the reason of inertia, and now wheel drives gearbox and motor rotation, because the gearbox speed ratio of electric vehicle is very large, thus the very large resistance of generation is slided to automobile, reduce coasting distance, waste electric energy.
Summary of the invention
Not enough for overcoming above-mentioned prior art, the invention discloses a kind of energy-conservation twin-direction clutch, electric motor car free sliding can be made, reduce resistance, save electric energy.
The technical solution adopted in the present invention is a kind of energy-conservation twin-direction clutch, comprise internal thread spline cover, outer spiral spline axle, driving ratchet, ratchet and friction spring, internal thread spline cover is passed in the middle of ratchet, at internal thread spline cover two ends, interference fit press-fits two driving ratchets, then friction spring is installed in the inner side of a driving ratchet wherein, friction spring has damping function, is finally screwed in internal thread spline cover by outer spiral spline axle.
The present invention also comprises friction sleeve, elastic spring, steel ball, friction sleeve is arranged on ratchet side, friction spring is between one of them driving ratchet and friction sleeve, direction, the ratchet end face vertical center of circle arranges penetrating circular hole, puts into steel ball, elastic spring, steel ball successively in penetrating circular hole.
Direction, the ratchet end face vertical center of circle arranges three penetrating circular holes, and steel ball and elastic spring is loaded in penetrating circular hole, when making the rotating speed of ratchet exceed input speed of the present invention, two driving ratchets all depart from ratchet, thus realize the function surmounting common clutch.
The interior basifacial of described outer spiral spline axle is parallel spline, and lower end, outside is screw key, and both sides, ratchet outer end are sawtooth tooth, is sawtooth tooth inside driving ratchet outer end, and internal thread spline cover inner face is screw key.
Working principle of the present invention is the cooperation utilizing helical spline, the parallel spline of the inner utilization of helical spline shaft imports power into outside, under the interaction of internal and external screw splined shaft, drive driving ratchet to produce and move axially, thus produce two-way clutch state with ratchet.
Advantage of the present invention:
The complete application machine principle of the present invention, creates the clutch state in kinetic energy transmission process, and without the need to the consumption of other energy, and it is little to rub.Structure is simple, intensity is high, durable.The present invention realizes the function surmounting ordinary clutch, and solve the problem that the coasting distance of current power automobile is near, belong to the blank field of the industry, the present invention also can be applicable to other drive technology fields.
Accompanying drawing explanation
Fig. 1 is sectional drawing of the present invention, and Fig. 2 is left view of the present invention.
Embodiment
As Fig. 1, shown in 2, a kind of energy-conservation twin-direction clutch, comprise internal thread spline cover 2, outer spiral spline axle 1, driving ratchet 8, ratchet 5, friction spring 3, friction sleeve 4, elastic spring 6 and steel ball 7, the interior basifacial of described outer spiral spline axle 1 is parallel spline, lower end, outside is screw key, both sides, ratchet 5 outer end are sawtooth tooth, be sawtooth tooth inside driving ratchet 8 outer end, it is screw key that internal thread spline overlaps 2 inner faces, internal thread spline cover 2 is passed in the middle of ratchet 5, ratchet 5 rotates freely on internal thread spline cover 2, overlap 2 two ends interference fit at internal thread spline and press-fit two driving ratchets 8, internal thread spline cover 2 is fixedly installed togather with driving ratchet 8, ratchet 5 can be engaged with two driving ratchets 8 respectively, then friction spring 3 is installed in the inner side of a driving ratchet 8 wherein, friction spring 3 has damping function, assistance realizes driving ratchet 8 and is engaged with ratchet 5, friction sleeve 4 is attached on ratchet 5 side, friction sleeve 4 and ratchet 5 rub mutually, friction spring 3 is between one of them driving ratchet 8 and friction sleeve 4, direction, the ratchet 5 end face vertical center of circle arranges penetrating circular hole, steel ball 7 is put into successively in penetrating circular hole, elastic spring 6, steel ball 7, internal thread spline overlaps 2 outer surface centers and arranges a circle groove, steel ball 7 snaps in wherein just, now ratchet 5 rotates freely at internal thread spline cover 2, be not engaged with any one driving ratchet 8, finally outer spiral spline axle 1 is screwed in internal thread spline cover 2.
Direction, the ratchet 5 end face vertical center of circle arranges three penetrating circular holes, and in penetrating circular hole, load steel ball 7 and elastic spring 6, when making the rotating speed of ratchet 5 exceed input speed of the present invention, two driving ratchets 8 all depart from ratchet 5, thus realize the function surmounting common clutch.
Claims (2)
