传统的液力变矩器循环圆大多数由多圆弧组成,对于单级向心涡轮变矩器更是如此。多圆弧型线有其固有的局限性。首先是很难达到沿轴面流线保持过流面积不变,往往出现扩散、收缩或局部波动。其次是各圆弧间虽然相切,但其曲率变化是不连续的,作为流线是不光滑的。多圆弧循环圆的设? Most of the traditional torque converter circular circle composed of multi-arc, single-stage radial turbine torque converter is even more so. Multi-arc line has its inherent limitations. The first is difficult to achieve along the axial flow line to maintain the flow area constant, often appear proliferation, contraction or local fluctuations. Followed by the arc between the tangent, but the curvature change is not continuous, as the streamline is not smooth. Multi-arc circular circle set?
