Go out outside gear housing and receive exogenous power.
The jackshaft, output shaft coaxial line and parallel with input shaft, are equipped with friction plate between jackshaft and output shaft
Clutch, the output shaft other end, which stretches out, externally exports power outside gear housing.First order driven tooth is installed on jackshaft
Wheel, first order driven gear are meshed with the first order driving gear on input shaft.
The directional overrunning clutch inner ring is fixedly connected with output shaft, and outer ring is fixedly connected with second level driven gear,
Second level driven gear is meshed with the second level driving gear on input shaft, first order driven gear and directional overrunning clutch point
Row friction disk clutch both sides.
Preferably, first order driving gear is in normal meshing state with first order driven gear.
Preferably, second level driving gear is in normal meshing state with second level driven gear.
Preferably, second level driving gear and the gearratio of second level driven gear are more than first order driving gear and first
The gearratio of grade driven gear.
The beneficial effects of the present invention are：
Compared with prior art, friction disk clutch formula two-stage self shifter of the invention, which becomes, turns round gear mechanism, mechanical structure
It is simple and reliable, size is small, at low cost, suitable for low cost electric vehicle.Two level automatic gear shifting speed changing torque can be achieved, solve electricity
Motor-car face complex road condition, such as persistently uphill way when, torque deficiency climbs the problem of not going up a slope, while extends the service life of motor.

Specific embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings：
A kind of friction disk clutch formula two-stage self shifter as shown in Figure 1, which becomes, turns round gear mechanism, including：Gear housing 1 and peace
Friction disk clutch two-stage self shifter Bian Niu mechanisms 2 in gear housing 1.
Friction disk clutch formula two-stage self shifter Bian Niu mechanisms 2 as shown in Figure 2 include input shaft 3, jackshaft 4, the
Level-one driving gear 5, first order driven gear 6, friction disk clutch 7, directional overrunning clutch 8, second level driven gear 9,
Two level driving gear 10 and output shaft 11, by normally closed type friction disk clutch 7 and mono-directional overrun formula clutch 8 according to difference
Input torque realize two-stage gear mechanism self shifter.
It is installed with first order driving gear 5, second level driving gear 10 on input shaft 3 successively, input shaft 3 is located at the
The end of 5 exterior portion of level-one driving gear, which is stretched out, receives exogenous power outside gear housing 1.
Jackshaft 4,11 coaxial line of output shaft and parallel with input shaft 3, are equipped with friction between jackshaft 4 and output shaft 11
Slice clutch 7,11 other end of output shaft, which stretches out, externally exports power outside gear housing 1.The first order is installed on jackshaft 4
Driven gear 6, first order driven gear 6 are meshed with the first order driving gear 5 on input shaft 3.
8 inner ring of directional overrunning clutch is fixedly connected with output shaft 11, and outer ring is fixedly connected with second level driven gear 9,
Second level driven gear 9 is meshed with the second level driving gear 10 on input shaft 3, first order driven gear 6 and override type from
Clutch 8 divides row friction disk clutch 7 both sides.
Second level driving gear 10 is in normal meshing state with second level driven gear 9, and gearratio, which is more than to be in, often to be nibbled
The first order driving gear 5 of conjunction state and first order driven gear 6.
Operation principle of the present invention is：
When the input torque of input shaft 3 is less than the setting torque of normally closed type friction disk clutch 7, jackshaft 4 and output shaft 11
Driving output shaft 11 is connected by normally closed type friction disk clutch 7 to rotate, second level driven gear 9 is under the drive of output shaft 11
Rotation, second level driving gear 10 is in normal meshing state with second level driven gear 9, still, due to first order driving gear 5
It is less than the gearratio of second level driving gear 10 and second level driven gear 9 with the gearratio of first order driven gear 6.At this point,
The rotating speed of second level driven gear 9 is greater than the rotating speed of second level driving gear 10, and directional overrunning clutch 8, which is in, surmounts state,
Second level driving gear 10 is transmitted with second level driven gear 9 without torque；
When the input torque of input shaft 3 is more than the setting torque of normally closed type friction disk clutch 7, normally closed type friction disk clutch
7, which start to skid, disconnects, and at this moment the rotating speed of output shaft 11 and second level driven gear 9 is less than the rotating speed of second level driving gear 10,
Directional overrunning clutch 8 engages, and second level driving gear 10 transmits torque drive output shaft 11 with second level driven gear 9 and rotates.
Since the gearratio of first order driving gear 5 and first order driven gear 6 is driven less than second level driving gear 10 and the second level
The gearratio of gear 9, at this point, 11 rotating speed of output shaft realizes that shift speed change increases compared to reducing before gearshift, and then output torque increases
It turns round.
It should be pointed out that embodiment described above is only the preferred embodiment of the present invention, for the art
Those of ordinary skill for, without departing from the principle of the present invention, several improvement can also be made, these improve also should
It is considered as protection scope of the present invention.
