Embodiment 1
As shown in Fig. 1~2, the electromagnetic type dog clutch features of the present embodiment include axis 50, coil block, throw-out collar group
Part, clutch active gear 31 and clutch passive tooth 32.The coil block includes main casing 11, electromagnetic coil 10 and end cap
12.The throw-out collar component includes throw-out collar outer ring 21 and the throw-out collar inner ring 22 that is entrenched in the throw-out collar outer ring 21.The electromagnetic wire
10 setting of circle is closed in the main casing 11 and by end cap 12.The coil block, clutch active gear 31 and from
Clutch passive tooth 32 is sleeved on successively on the axis 50.It is formed with annular between the coil block and the axis 50 and accommodates sky
Between.The throw-out collar component setting is in the annular accommodation space, the interior end in contact of the throw-out collar component and the coil block
And the inner end for capableing of the relatively described coil block moves in the axial direction, and stroke is X.And the throw-out collar component is by 50, axis
Support；The throw-out collar outer ring 21 is adjacent with the clutch active gear 31, and the clutch active gear 31 and clutch quilt
Moving teeth 32 abuts.It is provided with the sliding surface contacted with the axis 50 on the endoporus front-end and back-end of the throw-out collar inner ring 22, and institute
It states and is provided with inner fovea part between the front-end and back-end of throw-out collar inner ring, for accommodating lubricating oil with lubricating contact face.The main casing
11 and 12 closure of the end cap at formed jagged and so that be formed between the electromagnetic coil 10 and the throw-out collar outer ring 21
The air gap of connection.It is both provided with dental inlay tooth in the clutch active gear 31 and clutch passive tooth 32, and described
Dental inlay tooth is inverted cone-shaped structure.The spacing ring 52 of the restricted throw-out collar inner ring axial movement is set on the axis 50.It is described to push away
Ring outer ring is made of magnetic conductive material, and the throw-out collar inner ring is made of non-magnet material.As illustratively, throw-out collar outer ring by
S10 steel is made, and the throw-out collar inner ring is made of aluminium alloy.
It is provided with supply terminals on the electromagnetic coil, after the electromagnetic coil is powered, electromagnetic coil generates electromagnetism
And make the throw-out collar outer ring generate thrust, and the throw-out collar inner ring is pushed to push the clutch active gear and clutch
The passive tooth engagement of device.Baffle and return spring are provided in the clutch passive tooth, described after the electromagnetic coil power-off
The clutch active gear is set to be detached with the clutch passive tooth under the action of return spring.
Fig. 3 gives the principle of the off-state and bonding state transformation of the present embodiment electromagnetic type jaw clutch.Work as electricity
When magnetic coil powers off, it is located at throw-out collar outer ring 21 and throw-out collar inner ring 22 on the inside of electromagnetic coil and is in original state, clutch is actively
Both gear 31 and clutch passive tooth are in discrete state.After electromagnetic coil is powered, in the electromagnetic field that electromagnetic coil generates
Under the action of generate thrust and the throw-out collar outer ring pushed to move, stroke X under the promotion of throw-out collar outer ring as shown, drive
The throw-out collar inner ring moves forward and the clutch active gear is pushed to be moved to close to the direction of the clutch passive tooth
And the two is made to be in bonding state.According to electromagnetic induction principle, the calculation formula of the thrust is as follows：
Wherein：F is thrust, and N is the number of turns of electromagnetic coil, and i is the electrical current of electromagnetic coil, and u is the magnetic conductivity of air,
A is magnetic circuit sectional area, and x is the stroke of throw-out collar outer ring.According to the formula and required thrust size, the form of coil can be designed
With the parameters such as required coil turn.
The action process of the electromagnetic type dog clutch features of the present embodiment is respectively as shown in Fig. 4~8.As shown in figure 4, working as
Electromagnetic coil no power, clutch are off.As shown in figure 5, electromagnetic coil is powered, flux generates, wherein the magnetic line of force
