用于涡轮增压器的运动学上顺应的连杆机构
摘要：
连杆机构在涡轮增压器中的致动器和阀之间延伸。连杆机构包括两个间隔的构件本体，该构件本体具有中心部分，该中心部分具有在可沿着间隔的枢轴平移和绕间隔的枢轴旋转的端部之间延伸的相对的弯曲形状。一个构件朝向另一个构件的平移压缩中心部分，从而增加连杆机构的整体刚度，并且一个构件远离另一个构件的平移在中心部分之间产生间隙，从而允许端部沿间隔的枢轴独立平移以补偿因热和振动引起的致动器和阀门之间的不对齐。在涡轮增压器中的致动器和阀之间延伸的另一连杆机构包括两个平面间隔的构件本体，所述构件本体在可沿着间隔的枢轴平移并且可绕间隔的枢轴旋转的端部之间延伸。两个构件本体具有不同的厚度。
摘要（英）：

A linkage extends between an actuator and a valve in a turbocharger. The linkage comprises two spaced member bodies having central portions with opposing curved shapes that extend between ends translatable along and rotatable about spaced pivots. Translation of one member toward the other member compresses the central portions, increasing overall stiffness of the linkage, and translation of one member away from the other member creates a gap between the central portions, allowing independent translation of the ends along the spaced pivots to compensate for misalignment between the actuator and the valve caused by heat and vibration. Another linkage extending between an actuator and a valve in a turbocharger includes two planar spaced member bodies extending between ends translatable along and rotatable about spaced pivots. The two member bodies have different thicknesses.
