Axial flux joint motor system with integrated oil injection microcirculation cooling

An axial-flux joint motor module, comprising an axial flux joint motor and a two-stage planetary reducer;

• wherein the axial flux joint motor includes a non-driving-end stator, a driving-end stator, and a rotor;
• the non-driving-end stator and the driving-end stator are fixed together;
• the axial flux joint motor adopts direct oil injection cooling for the stator winding and combined oil cooling with the stator core;
• the non-driving-end stator and the driving-end stator share a common oil inlet channel and oil outlet;
• the non-driving-end stator includes a non-driving-end cover, and the driving-end stator includes a driving-end cover;
• the inner surface of the inner cavity of the non-driving end cover is provided with a first spiral-shaped oil passage, which is a single spiral ;
• the outermost circle of the first spiral-shaped oil passage is covered by a first oil thrower;
• the first oil thrower is provided with multiple first oil injection holes spaced circumferentially, which are used to spray the outer end of the stator winding;
• the innermost circle of the first spiral-shaped oil passage is covered by a second oil thrower, and the second oil thrower is provided with multiple second oil injection holes spaced circumferentially, which are used to spray the inner end of the stator winding;
• the middle spiral oil passage of the first spiral-shaped oil passage cools the stator core;
• and
• the inner surface of the inner cavity of the drive end cover is provided with a second spiral-shaped oil passage, which is a single spiral;
• the outermost circle of the second spiral-shaped oil passage is covered by a third oil thrower;
• the third oil thrower is provided with multiple spaced third oil injection holes along the circumferential direction, which are used for injecting oil at the outer end of the stator winding;
• the innermost circle of the second spiral-shaped oil passage is covered by a fourth oil thrower, and the fourth oil thrower is provided with multiple spaced fourth oil injection holes along the circumferential direction, which are used for injecting oil at the inner end of the stator winding;
• the middle spiral oil passage of the second spiral-shaped oil passage cools the stator core.
