电动的伺服转向装置及其初次装配方法
By introducing an assembly section with a second tooth height lower than the first tooth height and a recessed structure for the shaft through-hole in the rack design, the problem of difficult connection between the pinion shaft and the rack is solved, ensuring the stability and accurate positioning of the electric servo steering device during initial assembly and maintenance.

Abstract
本发明涉及一种电动的伺服转向装置以及一种用于初次装配电动的伺服转向装置的方法。所述电动的伺服转向装置具有用于使车辆的车轮转向的齿条(2)并且具有小齿轮轴(10)，所述小齿轮轴在装配状态中嵌入到齿条的齿列(6)中，并且齿条具有用于初次装配小齿轮轴的装配区段(8)，齿列的一个端部过渡到装配区段中。一方面为了便于初次装配以建立在小齿轮轴与齿条的齿列之间的连接，并且另一方面为了在初次装配之后实施的维修措施中防止松开在小齿轮轴与齿条的齿列之间的连接，齿列的第一齿(7)分别具有第一齿高，并且装配区段具有用于与小齿轮轴共同作用的第二齿(9)，所述第二齿分别具有小于第一齿高的第二齿高。
