Rotary transformer fixed structure and hybrid electric vehicle

Abstract

The invention relates to a rotary transformer fixed structure and a hybrid electric vehicle. The rotary transformer fixed structure comprises a motor and a rotary transformer which is fixed on the outside of the motor, wherein the motor comprises a motor end cover and a motor shaft which can rotatably penetrate the motor end cover through a bearing; the rotary transformer comprises a rotary transformer rotor, a rotary transformer stator fixed ring, a rotary transformer stator, an outer end cover and a rotary transformer lead-out line, wherein the rotary transformer rotor is fixed on the motorshaft which is arranged on the outside of the motor end cover; the rotary transformer stator fixed ring is fixed on the outside of the motor end cover; the rotary transformer stator is fixed on the rotary transformer stator fixed ring and corresponds to the rotary transformer rotor; the outer end cover is flexibly sleeved on the motor shaft and is fixed together with the rotary transformer stator; one end of the rotary transformer lead-out line is connected with the coil of the rotary transformer stator and the other end of the rotary transformer stator penetrates through the outer end cover and then leads out.

Description

【Technical field】 [0001] The invention relates to the application of a rotary transformer, in particular to a rotary transformer fixing structure applied to a hybrid electric vehicle. 【Background technique】 [0002] The resolver can be used to transmit the rotation angle or electric signal in the synchronous servo system and the digital servo system, and can be used as the solution of the function in the solving device, so it is also called the resolver. Although the structure and shape of the resolver are different from ordinary transformers, its basic working principle is exactly the same. The stator winding is equivalent to the primary coil of ordinary transformers, the rotor winding is equivalent to the secondary coil, and the rotor can rotate relative to the stator. However, the traditional resolver is usually installed inside the motor casing, that is, between the stator and the end cover, which brings a lot of inconvenience to its replacement inspection and later main...
