A wheel assembly bushing for an in-wheel motor wherein the bushing includes a hydraulic chamber positioned within a resilient sleeve of the bushing and a helical fluid passage extending helically around an inner bushing member between a first fluid passage end and a second fluid passage end, the first fluid passage end and the second fluid passage end are arranged in fluid communication with a hydraulic chamber. The outer body extends annularly around the resilient sleeve, which allows relative movement between the inner liner member and the outer body. The fluid passage is configured to generate inertia. When combined with other damping and stiffness effects of the wheel assembly bushing, this inertia provides phase and magnitude offsets between force and speed, which ultimately reduces magnetic gap deformation in the in-wheel motor.
一种用于轮内电动机的车轮组件衬套,其中该衬套包括定位在该衬套的弹性套筒内的液压室和围绕内衬套构件在第一流体通道端部与第二流体通道端部之间螺旋地延伸的螺旋流体通道,该第一流体通道端部和该第二流体通道端部被布置成与液压室流体连通。外主体围绕弹性套筒环状地延伸,这允许内衬套构件与外主体之间的相对运动。流体通道被构造成产生惯性。当与车轮组件衬套的其他阻尼和刚度效应组合时,该惯性提供了力与速度之间的相位和幅值偏移,这最终减小了轮内电动机中的磁隙变形。
