Fig. 1 is the present embodiment cross-sectional view of the structure.
Specific implementation mode
Invention is further described in detail with reference to the accompanying drawings and examples.
As shown in Figure 1, the present embodiment includes input shaft 23, sun gear 3, planetary gear 5, planet axis 2, pivoted frame 14, internal tooth
Wheel 4, output shaft 1 and casing 17, the output shaft 1 are fixedly connected with the internal gear 4, in the pivoted frame 14 and the internal gear
Between 4 denticle be equipped with the first friction clutch (6,7), between the pivoted frame 14 and the body 17 equipped with second rub from
Clutch (15,16), and it is additionally provided with clutch operating mechanism.
The clutch operating mechanism includes left electromagnetic coil 20, right electromagnetic coil 22, armature 21, left shift fork 9, right shift fork
11, pull rod 19, it is separated by a distance between the left electromagnetic coil 20 and 22 axial direction of right electromagnetic coil to be fixed on the machine
On shell 17, the armature 21 is located between the left electromagnetic coil 20 and the right electromagnetic coil 22,21 both ends of the armature point
It is not connected with upper and lower 19 one end of the pull rod, 19 other end of the pull rod passes through the casing 17 and 11 phase of right shift fork
Connection, the right shift fork 11 and the left shift fork 9 are connect being rotatably assorted radial through bearing 12, the right shift fork 11 with it is described
It is connected with each other by thrust bearing 10 between 9 axial direction of left shift fork, the second clutch pressure is equipped on the right side of the right shift fork 11
Land 14 is equipped with the first clutch pressure land 8 on the left side of the left shift fork 9.
The denticle of the first outside friction disc 7 and the internal gear 4 in first friction clutch (6,7) is slidably connected,
The first inner attrition piece 6 in first friction clutch (6,7) is slidably connected with the pivoted frame 14, second friction clutch
The second outside friction disc 16 in device (15,16) is slidably connected with the casing 17, in second friction clutch (15,16)
Second inner attrition piece 15 is slidably connected with the pivoted frame 14.But in order to process, it is easy for installation, the pivoted frame 14 passes through force transmiting disk 18
It is slidably connected with the second inner attrition piece 16 in second friction clutch.
In addition, in order to control the running temperature of speed reducer, ensure the reliability service of speed reducer and the service life of parts and strong
Degree, box body of speed reducer pass through upper, lower tube connector 24,25 external closed circulation water cooling heat radiating devices.
When left electromagnetic coil 20 must be electric, the electromagnetic force fast speed belt moving armature 21 that left electromagnetic coil 20 generates is moved to the left, so
First clutch pressure land 8 is pressed to and is rubbed outside first by 21 pushing drawing rod 19 of armature, right shift fork 11, thrust bearing 10, left shift fork 9 afterwards
Pad 7 and the first inner attrition piece 6 make the first outside friction disc 7 and the first inner attrition piece 6 combine rapidly, to by output shaft 1, interior
Gear 4 is integrally formed by the way that the first friction clutch (6,7) and pivoted frame are locked, and output shaft 1 realizes 1: 1 transmission, at this point, due to the
The effect that two friction clutches (15,16) do not stress is in discrete state.
When right electromagnetic coil 22 must be electric, the electromagnetic force fast speed belt moving armature 21 that right electromagnetic coil 22 generates moves right, so
Pull pull rod 19, right shift fork 11 that second clutch pressure land 13 is pressed to friction in the second outside friction disc 16 and second by armature 21 afterwards
Piece 15 makes the second outside friction disc 16 and the second inner attrition piece 15 combine rapidly, thus by pivoted frame and 17 second friction clutch of casing
Device (15,16) is locked to be integrally formed, and book speed reducer is conventional planet gear speed reducer, and output shaft 1 realizes that 1: 2.56 deceleration passes
It is dynamic, at this point, due to the effect that the first friction clutch (6,7) does not stress, it is in discrete state.
In conclusion the present invention has the advantage that compared with prior art：
