Description
Technical Field
The utility model relates to a motor connecting part in electric automobile axle field especially relates to an electric vehicle axle motor connection pad.
Background
At present, motor connecting discs used on axles of electric vehicles are mostly formed by stamping steel plates or casting and post-processing nodular cast iron, and are also formed by casting blanks by using cast steel parts. In the technical schemes, the material utilization rate of the processing after the stamping forming is adopted is low, the manufacturing cost is high, the investment cost of the die is high, the material cost of the nodular cast iron and the cast steel is high, and the overall cost of the motor connecting disc is influenced.
SUMMERY OF THE UTILITY MODEL
The utility model aims at overcoming the above-mentioned not enough of prior art and providing an electronic axle motor connection pad, have simple structure, convenient operation, production low in manufacturing cost, processing and balancing performance are good, long service life.
In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides an electronic axle motor connection pad, characterized by: the novel steel pipe joint comprises a left circular disc, a middle conical round platform and a right circular ring connecting disc, wherein the left circular disc, the middle conical round platform and the right circular ring connecting disc are connected through arc angles so as to avoid stress concentration to form cracks.
The utility model discloses further technical scheme is: the left side end face of the right circular ring connecting disc is a pentagonal or polygonal pit, five or more connecting holes are formed in the periphery of the right circular ring connecting disc, and the right circular ring connecting disc is connected with a flange at one end of a corresponding motor output shaft through bolts.
The utility model discloses a further technical scheme is: the middle of the left circular disc is provided with a through hole, the periphery of the left circular disc is designed into a lace shape, and a plurality of through holes are arranged along the periphery of the left circular disc and are connected with the speed changer through bolts.
The utility model discloses still further technical scheme is: the motor connecting disc is cast by adopting a special casting die, the casting material is HT250, a casting blank needs normalizing treatment, the hardness after normalizing treatment is HB 190-270, and pearlite reaches more than 50%; the blank is not allowed to have the defects of cracks, sand holes, air holes, shrinkage porosity and the like.
Compared with the prior art, the utility model has the following characteristics:
the utility model has the advantages of simple structure, convenient operation, low in manufacturing cost, processing and balance performance are good, long service life and application scope are wide, can satisfy the actual need of many varieties axle.
The detailed structure of the present invention will be further described with reference to the accompanying drawings and the detailed description.
Drawings
