The vehicle tailgate lift assist system includes: a vehicle tailgate adapted to be opened and closed by rotating about a tailgate pivot axis relative to a vehicle body; a coupling device for releasably connecting the vehicle tailgate and the vehicle body; an energy storage device located within the vehicle body and adapted to be pivotally anchored to the vehicle body at one end; a crank arm pivotally attached to the energy storage device at a second end of the energy storage device and rigidly attached to an actuation shaft coaxially aligned with the tailgate pivot axis; and a pivot bracket assembly including a mounting bracket secured to the vehicle body and holding the pivot support arrangement to facilitate secure rotational engagement about the tailgate pivot axis. The pivot support arrangement includes a one-piece component overmolded to the pivot sleeve for use as a bushing between the actuation shaft and the pivot sleeve such that relative rotational movement of the tailgate and the vehicle body results in linear movement of the energy storage device and maximization of energy storage in a position where the tailgate is fully open.
车辆后挡板提升辅助系统包括:适于通过相对于车身围绕后挡板枢转轴线进行旋转来打开及关闭的车辆后挡板;用于以可释放的方式将车辆后挡板和车身连接的联接装置;位于车身内且适于在一个端部处以可枢转的方式锚固至车身的能量储存装置;曲柄臂,其在能量储存装置的第二端部处以可枢转的方式附接至能量储存装置且刚性地附接至以同轴的方式与后挡板枢转轴线对准的致动轴;以及枢轴支架组件,其包括安装支架,该安装支架被固定至车身并且对枢轴支承布置结构进行保持,以便于实现围绕后挡板枢转轴线的稳固旋转接合。枢轴支承布置结构包括一体式部件,其被包覆模制到枢轴套筒以用作致动轴与枢轴套筒之间的衬套,使得后挡板和车身的相对旋转运动导致能量储存装置线性地运动以及在后挡板完全打开的位置处使能量储存最大化。
