The invention discloses a connecting structure of a motor and an electric power steering oil pump, a power steering system and an automobile, and relates to the technical field of power steering systems. The connecting structure of the motor and the electric power steering oil pump comprises a motor shaft and a pump head shaft, wherein a regular pattern groove is arranged at the front end of the motor shaft along the axial direction, and a pattern shaft used for being inserted into the pattern groove is fixed at the front end of the pump head shaft along the axial direction. According to the invention, the front end of the motor shaft is provided with the regular pattern groove along the axial direction, the pattern shaft used for being inserted into the pattern groove is fixed at the front end of the pump head shaft along the axial direction at the same time, and the pattern groove has a regular pattern structure, so that alignment is not needed when the pattern groove and the patternshaft are assembled. When the assembling angle of the pattern groove and the assembling angle of the pattern shaft are inconsistent, the assembling can be completed only by rotating the motor shaft or the pump head shaft, the installation of the motor and the pump head becomes simple, and meanwhile, the installation steps and installation time of the motor and the pump head can be reduced.
一种电机与电动助力转向油泵的连接结构、助力转向系统、汽车,涉及助力转向系统技术领域,该电机与电动助力转向油泵的连接结构包括电机轴和泵头轴,所述电机轴的前端沿轴向开设有规则的花型槽,所述泵头轴的前端沿轴向固定有用于插入所述花型槽内的花型轴。本发明通过在电机轴的前端沿轴向开设规则的花型槽,同时在泵头轴的前端沿轴向固定用于插入花型槽内的花型轴,由于花型槽具有规则的花型结构,使得花型槽与花型轴在装配的时候无需对准,当花型槽与花型轴的装配角度不一致时,只需转动电机轴或泵头轴,即可完成装配,使电机与泵头的安装变得简单,同时可以减少电机与泵头的安装步骤、安装时间。
