Abstract
A wheel assembly bushing for in-wheel electric motors where the bushing includes a hydraulic chamber positioned within a resilient sleeve of the bushing and a helical fluid channel that extends helically about an inner bushing member between first and second fluid channel ends, which are arranged in fluid communication with the hydraulic chamber. An outer body extends annularly about the resilient sleeve, which permits relative movement between the inner bushing member and the outer body. The fluid channel is configured to produce inertance. This inertance, when combined with other damping and stiffness effects of the wheel assembly bushing, provides phase and magnitude shifts between force and velocity, which ultimately reduce magnetic gap deformation in the in-wheel electric motor.
