The invention relates to a shock-absorption buffer shaft. The shock-absorption buffer shaft comprises an input shaft, an input end cover, a force transfer pin, an input toothed sleeve, an input toothed wheel, a double toothed wheel, a spring, an output toothed sleeve, an output toothed wheel, an output shaft, an output end cover, a limiting bolt, a fastening bolt and an external sleeve. Force is transferred to the input toothed sleeve by virtue of the teeth of the first internal toothed ring of the input toothed sleeve in a manner of compressing a spring through the teeth of an external toothed ring on the input toothed wheel, later the force is transferred to the double toothed wheel by virtue of the teeth of the first external toothed ring of the double toothed wheel in a manner of compressing the spring through the teeth of the second internal toothed ring of the input toothed sleeve, then the force is transferred to the output toothed sleeve by virtue of the teeth of the first internal toothed ring of the output toothed ring in a manner of compressing the spring through the teeth of the second external toothed ring of the double toothed wheel, and then the force is transferred to the output toothed wheel by virtue of the teeth of the external toothed ring of the output toothed wheel in a manner of compressing the spring through the teeth of the second internal toothed ring of the output toothed sleeve, and finally, the output toothed wheel is used for transmitting the torque by virtue of the force transfer pin through the output shaft.

The invention discloses a multi-air-gap axial magnetic flow-magnetic field modulation permanent magnet motor, which comprises a plurality of stators and a plurality of rotors, wherein the stators and the rotors are sequentially in staggered arrangement in the axial direction; the two ends of the permanent magnet motor are two surface-mounted permanent magnet rotors; the other rotors are embedded permanent magnet rotors; the structure dimensions of the plurality of stators are identical; the stators are subjected to two-edge grooving and use annular windings; and each stator sequentially deviates for the mechanical angle of the half groove distance relative to the former stator in the circumference direction. The multi-air-gap axial magnetic flow-magnetic field modulation permanent magnet motor realized according to the invention can comprehensively solve the inherent problems of magnetic field modulation motor torque density limitation and low power factor on the basis of remaining good performance of a magnetic field modulation motor.

The invention relates to a smoothing control for working mode switching and torque of a hydrostatic transmission double-motor vehicle and belongs to a control method for a switching process of a hybrid power vehicle. Distinguishing for a working mode of a vehicle is realized by detecting a vehicle speed and a pedal signal; a hydraulic pump motor and a hydraulic motor are reasonably selected to coordinate and work, thereby promoting the transmission efficiency and pavement adaptability of a serial hybrid power vehicle; and during a process of working mode switching, a method for using an on-line calculating working element to output a torque and dynamically adjust an output torque of a to-be-inserted element is adopted to smoothen the output torque of the whole vehicle, thereby avoiding the phenomena of interrupted driving torque and oversize driving torque during the working mode switching, promoting driving performance and riding comfortableness of the vehicle, and efficiently lowering the cost. The control method has the advantages that the driving performance and riding comfortableness of the vehicle are promoted, the cost is efficiently lowered, a mechanical power distributing device is conveniently arranged, and the torque of a hybrid power engine can be accurately calculated.
