The invention relates to a power-assisted drive (18) for a steering system (1) of a motor vehicle, comprising a motor (4) which has a motor housing (41) which is connected to a transmission housing (51) of a transmission (5) by means of a flange connection which is axial with respect to a drive axis (A), according to the invention, the booster drive comprises corresponding flange elements (42, 52) which are arranged on the motor housing (41) and the transmission housing (51) and which each have an axial front face (421, 521) facing away from the housing and a rear face (422, 522) facing away from the housing and axially opposite the front face, the front face (421, 521) and the rear face (422, 522) projecting radially outward, a clamping mechanism (7) acts on the flange elements (521, 522), said clamping mechanism axially clamping the front faces (421, 422) of the flange elements (42, 52) to each other. In order to be able to reduce the production and assembly effort, the invention proposes that the clamping mechanism has at least one clamping element (7) which surrounds the flange element (42, 52) from the outside and has a clamping leg (75) which can be clamped axially from the outside towards the rear surface (521, 522).

    本发明涉及一种用于机动车的转向系统(1)的助力驱动装置(18),包括马达(4),所述马达具有马达壳体(41),所述马达壳体通过关于驱动轴线(A)轴向的法兰连接与传动机构(5)的传动机构壳体(51)连接,所述助力驱动装置包括布置在所述马达壳体(41)和所述传动机构壳体(51)上的、相对应的法兰元件(42,52),所述法兰元件分别具有远离壳体的轴向的正面(421,521)和轴向地与所述正面相对置的、靠近壳体的背面(422,522),其中所述正面(421,521)和所述背面(422,522)径向向外突出,并且夹紧机构(7)作用在所述法兰元件(521,522)上,所述夹紧机构将所述法兰元件(42,52)的正面(421,422)轴向地彼此夹紧。为了能够降低制造和装配耗费,本发明提出,夹紧机构具有至少一个夹持元件(7),该夹持元件从外部包围法兰元件(42,52)并且具有可从外部轴向地朝背面(521,522)夹紧的夹紧腿(75)。
