One end of the stator iron sleeve is provided with a flange, which is provided with at least three installation supporting lugs with bolt through holes along a peripheral direction. One of the installation supporting lugs is provided with a first positioning hole, and an end surface of an opening end of the motor housing is provided with at least three bolt holes and a second positioning hole along a peripheral direction. A first step is disposed between an outer wall of the stator steel sleeve and the flange, and the opening end of the motor housing is provided with a second step. The stator iron sleeve is disposed in the motor housing, and heat conduction materials are disposed between the outer wall and the motor housing in a filled manner. The first step and the second step are in a clearance fit, and positioning pins are inserted in the first positioning hole and the second positioning hole. The stator steel sleeve is fixedly disposed on the motor housing by the bolts, the bolt through holes, and the bolt holes. The assembling structure is advantageous in that under the precondition of guaranteeing the good heat dissipation performance of the motor stator, the position precision requirement on the positioning holes, which are disposed in the motor housing and are assembled with the motor and the decelerator, can be guaranteed.
Description
Technical field
The utility model relates to ISG motor, is specifically related to a kind of assembly structure of ISG motor stator.
Background technology
At present, Hybrid Vehicle ISG Motor adopts finger setting, clamping screw to be connected with engine, decelerator, and this connecting-type mode is higher to the position accuracy demand of the location hole on electric machine casing.Publication number is the assembly structure that the patent of CN 102130555 A discloses a kind of electric machine casing and Motor Stator Assembly, and by Motor Stator Assembly hot jacket, in housing, this structure is conducive to the heat radiation of Motor Stator Assembly.But because this kind of assembling form need heat electric machine casing, and heating-up temperature is higher, the position degree of cooling rear motor housing location hole there will be uncertain deviation, thereby makes electric machine casing position of positioning hole degree consistency poor, will cause the assembling difficulty of motor and engine, decelerator.
Summary of the invention
The purpose of this utility model is to provide a kind of assembly structure of ISG motor stator, is guaranteeing that motor stator has under the prerequisite of better thermal diffusivity, can guarantee the position accuracy demand of the location hole that assembles with engine, decelerator on electric machine casing.
The assembly structure of ISG motor stator described in the utility model, comprise electric machine casing and be arranged on the field frame assembly in electric machine casing, field frame assembly comprises stator core and the stator steel bushing setting gradually from the inside to surface, one end of stator steel bushing has flange, on the flange of stator steel bushing, edge is circumferentially provided with the installation journal stirrup of at least three strap bolt via holes, on an installation journal stirrup, offer the first location hole therein, the openend end face of electric machine casing is along circumferentially offering at least three bolts hole and the second location hole; Between stator steel bushing outer wall and described flange, be provided with first step, openend at electric machine casing is provided with second step, stator steel bushing is positioned at electric machine casing, between its outer wall and electric machine casing, be filled with Heat Conduction Material, its first step and described second step matched in clearance, and between the first location hole and the second location hole, and bolt through-hole is corresponding one by one with the position between bolt hole, in first, second location hole, be inserted with alignment pin, stator steel bushing is fixed on electric machine casing by bolt, bolt through-hole and bolt hole.
The utility model is by colding pressing and bolt connects field frame assembly and electric machine casing are assembled, because electric machine casing in assembling process does not need heating, thereby guaranteed the position accuracy demand of the location hole that assembles with engine, decelerator on electric machine casing, from processing the consistency that has guaranteed product, improved the qualification rate of product.By fill Heat Conduction Material between stator steel bushing and electric machine casing, guaranteed that motor stator has good thermal diffusivity.
