The invention relates to a steering gear for a steering system of a motor vehicle, comprising a housing, a gear, a pinion, which meshes with the gear, and a pinion shaft, which comprises the pinion. On one side of the pinion, the pinion shaft is mounted in a fixed bearing, which comprises a rotary bearing (11), in which the pinion shaft is accommodated and which is accommodated in a bearing sleeve(15). The fixed bearing (6) also comprises a pivot ring (16), which has an outer ring (18) and an inner ring (17), which are connected to each other by means of one or more torsion webs (19) in sucha way that pivoting about a pivot axis (7) defined by the one or more torsion webs (19) is enabled, the inner ring (17) being accommodated in the bearing sleeve (15) and the outer ring (19) being mounted in the housing. A steering gear of this type is characterized in that the axial width of the torsion webs (19) and of first portions (27) of the outer ring (18) and of the inner ring (17) which are radially adjacent to the torsion webs (19) is smaller than the axial width of second portions (28) of the outer ring (18) and of the inner ring (17) which are adjacent to the first portions (27) inthe two circumferential directions. Thus, motions of the torsion webs (19) and of the first portions (27) based on deformation of the pivot ring (16) can be possible without contact between these parts of the pivot ring (16) and the components axially adjacent thereto.
设置一种用于机动车的转向系统的转向传动机构,该转向传动机构具有壳体、齿轮、与所述齿轮相啮合的小齿轮以及包括所述小齿轮的小齿轮轴,其中所述小齿轮轴在所述小齿轮的一侧上在固定轴承中受支承,所述固定轴承包括旋转轴承(11),在所述旋转轴承中接收所述小齿轮轴并且所述旋转轴承被接收在轴套(15)中。此外,所述固定轴承(6)包括枢转环(16),该枢转环具有外环(18)和内环(17),所述外环和内环通过一个或者多个扭转接片(19)以能围绕着通过所述一个或者多个扭转接片(19)限定的枢转轴线(7)枢转的方式彼此连接,其中所述内环(17)被接收在所述轴套(15)中并且所述外环(19)在所述壳体中受支承。这样的转向传动机构的特征在于,所述扭转接片(19)的轴向宽度以及所述外环(18)及所述内环(17)的在径向上与扭转接片(19)邻接的第一区段(27)的轴向宽度小于所述外环(18)及所述内环(17)的沿着两个圆周方向与第一区段(27)邻接的第二区段(28)的轴向宽度。由此能够实现这一点,即:所述扭转接片(19)及第一区段(27)的、基于枢转环(16)的变形的运动是可能的,而不会出现所述枢转环(16)的这些部件与在轴向上与其邻接的构件的接触。
