Detailed description of the invention
Below in conjunction with the accompanying drawings the present invention is described in detail.
With reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7 and Fig. 8, a kind of motor-driven jaw clutch formula vehicle backing
Gear structure, including power shaft 1, is arranged on the first sleeve 3 by the first deep groove ball bearing 2 and needle bearing 16 in the middle part of power shaft 1
In, the first sleeve 3 is arranged on fixed flat planar 5, on the left of fixed flat planar 5 on be fixed with jaw clutch 8, the first sleeve 3 is left
Side and the second deep groove ball bearing 11 inner ring are matched in clearance, and the second deep groove ball bearing 11 is by the second sleeve 15 and planet carrier 9 phase
Even, planet carrier 9 is connected with 4 planetary gears 13 by 12,8 the 3rd deep groove ball bearings 14 of 4 planetary gear axles, planetary gear
13 and the outer flank of tooth of power shaft 1, the inner toothed surface of output wheel 10 connected by flank engagement, be connected with shift fork 6 outside planet carrier 9,
Being provided with feed screw nut 7 on shift fork 6, connect the output shaft of motor 4 in feed screw nut 7, the output shaft of motor 4 is as leading screw and leading screw
Nut 7 coordinates；
Planet carrier 9 can engage with the left side tooth of jaw clutch 8 to right translation, the right side tooth of planet carrier 9；Planet carrier
9 can engage with the right side tooth of output wheel 10 to left, the left side tooth of planet carrier 9；Adjust the position of planet carrier 9, planet carrier 9
The right side tooth of left side tooth and output wheel 10 disengage, the right side tooth of planet carrier 9 and the left side tooth of jaw clutch 8 also can simultaneously
Enough disengagings.
The operation principle of the present invention is:
With reference to Fig. 9, power shaft 1 and internal combustion engine and motor being connected during use, output wheel 10 and change speed gear box connect, when needing
Being operated in when reversing gear position, motor 4 is rotated as the power source of gearshift, the output shaft band movable wire of motor 4
Thick stick nut 7 carries out axial translational movement, and the translational motion of feed screw nut 7 passes to planet carrier 9 by shift fork 6, by controlling electricity
Machine 4 just can change the horizontal level of planet carrier 9, when planet carrier 9 to right translation until planet carrier 9 right side tooth with castellated from
When the left side tooth of clutch 8 engages, output wheel 10 rotates with power shaft 1 opposite direction reduction of speed, it is achieved the deceleration gear reversing function of automobile.
When needs are operated in forward gear position, change the horizontal level of planet carrier 9 by controlling motor 4, when planet carrier 9
During to left until the left side tooth of planet carrier 9 engages with the right side tooth of output wheel 10, output wheel 10 is equidirectional with power shaft 1 same
Rotating speed rotates, it is achieved the forward gear function of automobile.
When needs are operated in neutral gear position, change the horizontal level of planet carrier 9 by controlling motor 4, when planet carrier 9 is flat
The right side tooth of the left side tooth and output wheel 10 that move on to planet carrier 9 disengages, the right side tooth of planet carrier 9 and a left side for jaw clutch 8
When side tooth also departs from, the motion of output wheel 10 is no longer relevant with power shaft 1, it is achieved the neutral function of automobile.
