Coaxial reverse power unit without mechanical differential

Abstract

The invention discloses a coaxial inversion power device without mechanical differential, comprising an inner shaft, an outer shaft, a reluctance rotor, a permanent magnet rotor, a stator and a driving device. The outer shaft is sleeved on the inner shaft and is coaxial with the inner shaft. The shaft is arranged, one end of the inner shaft protrudes from the outer shaft, the reluctance rotor is connected with one of one end of the inner shaft and one end of the outer shaft, the permanent magnet rotor is connected with the other one of the inner shaft and one end of the outer shaft, and the permanent magnet rotor is connected with one end of the inner shaft and one end of the outer shaft. The reluctance rotor is coaxially arranged, the stator is arranged coaxially with the reluctance rotor and is arranged on the inner side or outer side of the reluctance rotor opposite to the permanent magnet rotor, and the stator includes a stator iron core and a main winding and auxiliary windings wound around the stator iron core. winding, and the driving device is connected with the main winding and the auxiliary winding to drive the main winding and the auxiliary winding, respectively. The coaxial inversion power device without mechanical differential has the advantages of simple and compact structure, small space occupation, high integration, low failure rate, low vibration and flexible dynamic response, and can realize coaxial rotation of two axes and high efficiency.

Description

technical field [0001] The present invention relates to the technical field of power equipment, and more specifically, to a non-mechanical differential coaxial reversing power device. Background technique [0002] At present, the power generated by the power source of an ordinary coaxial reversing device often needs to pass through the gear differential, so that the power is distributed to the two output shafts that rotate in opposite directions, which not only reduces the transmission efficiency, but also complicates the mechanical differential structure. It is also easy to cause a substantial increase in the system failure rate. [0003] Part of the coaxial reversing device in the related art is realized by combining a hollow shaft motor and a solid shaft. However, using this method to realize the coaxial reversing will easily reduce the integration of the system and increase the system failure rate. Moreover, Larger volume, more inconvenient to use.
