Pipe, sliding sleeve drive yoke bar, shift fork, forward and backward sliding block and annular allocating slot to push to the left, and the colored pawl left end plane that synchronizes connects
It touches big variable block gear right end plane to also fail into when synchronizing circular hole, piston head pushes right thrust spring continuation to push to the left, directly
When to the cylinder permanent magnet of driving plate lower end close to left Hall switch, Hall switch triggers intelligent controller cutting shifting motor
Power supply drives screw rod and driving plate to stop, and screw rod and driving plate is driven to have self-locking function when stopping, and synchronizes colored pawl and big
Variable block gear is planar friction when relatively rotating, and for the two revolving speed close to when synchronizing, the elastic force promotion of right thrust spring synchronizes colored pawl
Into the synchronization circular hole of big variable block gear, bottom gear engagement is realized；Conversely, when the reversion of the drive shaft of shifting motor, driving plate
It moves right, the cylinder permanent magnet stops close to right Hall switch, shifting motor, and the elastic force promotion of left thrust spring synchronizes flower
Pawl enters the synchronization circular hole of small variable block gear, realizes top gear engagement, elastic force clutch is between bottom gear, neutral gear and top gear
During converting repeatedly, being engaged under flexible drive state for positive and negative clutch part is carried out, and engages close under synchronous regime, institute
The intelligent controller stated, according to the payload of power motor, the variation of revolving speed speed, automatically control shifting motor carry out it is high,
Low speed variable block, time-varying bottom gear of starting to walk, normal speed per hour get higher speed gear, and when upward slope is lower speed gear automatically.
3. automatic spring gear shifting differential speed motor according to claim 1, it is characterised in that: the power motor is 8 extremely interior
The brushless permanent magnet motor of rotor, tach signal come from commutation circuit, dynamic current of the motor load signal from power motor,
The shifting motor is that have brush magneto, and the speed probe is magnetoelectric tachometric transducer, and the intelligent controller is
The dual controller of power motor and shifting motor, intelligent controller is according to setting program, according to operating condition adjust automatically gear, automatically
The revolving speed of motivation of adjustment motor, making middle shaft gear and variable block gear, outlet hole (69) are arranged in power motor left end cap close to synchronous,
Wiring holes is arranged in the left shell half on the right in the protection box, and cable socket (70) are arranged in left shell half left upper end, sets in cable socket
It sets cable plug (71), the connection of cable socket and plug is multi-thread connection, and the output line of power motor passes through outlet hole, along change
Fast device inner walls connecting cable outlet terminal, shifting motor output line pass through wiring holes, connect along case of transmission inner wall
Cable socket terminals connect the intelligent controller output end by cable plug, Hall switch and speed probe it is defeated
Wiring holes connecting cable outlet terminal is passed through in outlet, connects intelligent controller input terminal by cable plug, cable plug connects
Line end connects output bus (72), and output bus connects intelligent controller, provides switching signal, middle shaft gear to intelligent controller
Tach signal, power motor tach signal and motor load signal, intelligent controller control shifting motor forward and backward and stopping,
The revolving speed of power motor is controlled simultaneously.
