摘要： The invention relates to blade for a stator of a torque converter, comprising a first blade segment which is connected to internal and external peripheral sections of the stator, and a second blade segment which is formed separately from the first blade segment and is connected to the circumferential sections. The invention is characterised in that the edges of the blade segments touch each other, overlap, are offset around the circumference and are at least partially folded, punched and cast. Arrangements of the blade segments can be selected such that performance characteristics of the stator, for example, torque ratio, degree of efficiency and output are modified. The invention is further characterised in that the blade segments are aligned around the circumference, and the stator comprises an alignment element that is arranged in a functional manner such that it controls the alignment around the circumference, for example, in response to the pressure of a liquid on the blades in the stator. The invention is also characterised in that the stator comprises axial halves which are formed separately and are rigidly connected together. The blade segments are connected to corresponding halves.
