Transmission principle and the operating process of the utility model automatic transmission are:

Be described with the second gear wheel hub motor embodiment of automatic transmission, as shown in Figure 7, it belongs to moment of torsion automatic gear-shifting, the Effector of gear axle assembling is when moment of torsion increases, the active force of helical tooth strengthens, flip sleeve is forced to slide to left end, return spring is compressed, the link press span that flip sleeve is fixed promotes initiatively frame left, initiatively frame relation control frame is moved to the left and the spring of compression is constantly changed the pressure direction from moving frame, when pressure direction changes into moment from left to right from right to left, counteragent device quicks rebound and to promote from moving frame from left to right, the fixing rotation combination of wheel hub be separated with mobile combination the mobile combination movement from left to right transmission COMM communication from moving frame sliding sleeve promotion guide rod and realize one grade of transmission, when when the speed of a motor vehicle after vehicle launch is accelerated, moment of torsion reduces, return spring forces flip sleeve to slide to right-hand member, the link press span that flip sleeve is fixed promotes initiatively frame to the right, initiatively frame relation control frame moves right and the spring of compression is constantly changed the pressure direction from moving frame, when pressure direction changes into moment from right to left from left to right, counteragent device quicks rebound and to promote from moving frame from right to left, the fixing rotation combination of wheel hub be combined with mobile combination the mobile combination movement from right to left transmission COMM communication from moving frame sliding sleeve promotion guide rod and realize second gear transmission.Shown in Fig. 7, one grade is in jointing state, illustrates that automatic transmission is in the slow-revving running state of high pulling torque.

Although carried out foregoing description to the utility model by reference to the accompanying drawings; but the utility model is not limited to above-mentioned embodiment; above-mentioned embodiment is only schematic; instead of it is restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; when not departing from the utility model aim, can also make a lot of distortion, these all belong to the row of protection of the present utility model.
