Abstract
Bidirectional clutch is saved the invention discloses one kind, belong to drive technology field, particularly electric automobile field, including internal thread spline set, outer spiral spline axle, driving ratchet, ratchet and friction spring, internal thread spline set is passed through in the middle of ratchet, at internal thread spline set two ends, interference fit press-fits two driving ratchets, and friction spring is then installed on the inside of advance driving ratchet, finally screws in outer spiral spline axle in internal thread spline set.The present invention can realize two-way clutch and surmount the function of common clutch.
Description
Technical field
The present invention relates to technical field of automobile transmission, particularly a kind of device for separating drive shaft with wheel can also be answered
For other transmission fields, and realize the function of surmounting common clutch.
Background technology
Existing electric automobile drives for motor, during traveling, and when unclamping accelerator, motor shuts down, but
It is that vehicle body may proceed to move ahead due to inertia, now wheel drives gearbox and motor operating, due to the change of electric automobile
Fast case speed, so as to produce very big resistance to sliding for automobile, reduces coasting distance, wastes electric energy than very big.
The content of the invention
To overcome above-mentioned prior art not enough, bidirectional clutch is saved the invention discloses one kind, electric car can be made certainly
By sliding, resistance is reduced, electric energy is saved.
The technical solution adopted in the present invention is that one kind saves bidirectional clutch, including internal thread spline set, external spiral flower
Key axle, driving ratchet, ratchet and friction spring, internal thread spline set are passed through in the middle of ratchet, in interior Turbo Flora
Key set two ends interference fit press-fits two driving ratchets, then installs friction spring on the inside of a driving ratchet wherein,
Friction spring has damping action, finally screws in outer spiral spline axle in internal thread spline set.
Present invention additionally comprises friction sleeve, elastic spring, steel ball, friction sleeve is arranged on ratchet side, rub bullet
Spring is located in one of between driving ratchet and friction sleeve, and the vertical center of circle direction of ratchet top surface sets penetrating circular hole, penetrating
Steel ball, elastic spring, steel ball are sequentially placed into circular hole.
The vertical center of circle direction of ratchet top surface sets three penetrating circular holes, and loading steel ball and elastic force in penetrating circular hole
Spring so that when the rotating speed of ratchet exceedes the input speed of the present invention, two driving ratchets are all de- with ratchet
From so as to realize the function of surmounting common clutch.
The inner face bottom of the outer spiral spline axle is parallel spline, and outside lower end is screw key, ratchet outer end two
It is sawtooth tooth on the inside of sawtooth tooth, driving ratchet outer end that side, which is, and internal thread spline set inner face is screw key.
The operation principle of the present invention is the cooperation using helical spline, in the parallel spline of the inner utilization of outer helical spline shaft
Incoming power, under the interaction of interior outer spiral spline axle, drives driving ratchet to produce axial movement, so that and ratchet
Produce two-way clutch state.
Advantages of the present invention：
The present invention applies theory of mechanics completely, the clutch state in kinetic energy transmission process is generated, without other energy
Consumption, and rub it is small.Simple in construction, intensity is high, durable.The present invention realizes the function of surmounting ordinary clutch, solves
The problem of coasting distance of current electric automobile is near, belongs to the blank field of the industry, it is also possible to apply the invention to other transmissions
Technical field.
Brief description of the drawings
Fig. 1 is profile of the present invention, and Fig. 2 is left view of the invention.
Embodiment
As shown in Figure 1, 2, a kind of energy-conservation bidirectional clutch, including internal thread spline set 2, outer spiral spline axle 1, active spine
Wheel 8, ratchet 5, friction spring 3, friction sleeve 4, elastic spring 6 and steel ball 7, the inner face bottom of the outer spiral spline axle 1
For parallel spline, outside lower end is screw key, and the outer end both sides of ratchet 5 are for saw on the inside of sawtooth tooth, the outer end of driving ratchet 8
Teeth, it is screw key that internal thread spline, which covers 2 inner faces, internal thread spline set 2 is passed through in the middle of ratchet 5, ratchet 5 exists
Rotated freely on internal thread spline set 2, covering 2 two ends interference fit in internal thread spline press-fits two driving ratchets 8, inside spin flower
Key set 2 is fixedly installed togather with driving ratchet 8, and ratchet 5 can be engaged with two driving ratchets 8 respectively, then at it
In the inner side of a driving ratchet 8 install friction spring 3, friction spring 3 has damping action, and driving ratchet 8 is realized in assistance
It is engaged with ratchet 5, friction sleeve 4 is attached on the side of ratchet 5, friction sleeve 4 and the rubs mutually of ratchet 5, friction
Spring 3 is located in one of between driving ratchet 8 and friction sleeve 4, and the vertical center of circle direction of the top surface of ratchet 5 sets penetrating circle
Steel ball 7, elastic spring 6, steel ball 7 are sequentially placed into hole, penetrating circular hole, internal thread spline covers the centrally disposed circle of 2 outer surfaces
Groove, steel ball 7 is caught in wherein just, and now ratchet 5 is rotated freely in internal thread spline set 2, not with any one actively
Ratchet 8 is engaged, and finally screws in outer spiral spline axle 1 in internal thread spline set 2.
The vertical center of circle direction of the top surface of ratchet 5 sets three penetrating circular holes, and loading steel ball 7 and bullet in penetrating circular hole
Power spring 6 so that the rotating speed of ratchet 5 exceed the present invention input speed when, two driving ratchets 8 with passive spine
Wheel 5 departs from, so as to realize the function of surmounting common clutch.
