Abstract: The present disclosure provides a grinding robot for an inside wall of a small diameter pipe. The grinding robot includes a grinding device, a transmission device, and a driving device. By arranging the grinding robot into the above three portions, the overall bending pipe passability of the robot can be increased, which is convenient for the grinding robot to grind the small diameter pipe. A first gimbal and two second gimbals provided in the transmission device enable the grinding robot to flexibly pass through bends of the pipe, and enable a grinding driving force to be variably transmitted to the grinding device. When the grinding body rotates and contacts a pipe wall, a reaction force of the pipe wall on the grinding body is balanced by an adjusting spring adjustment force in a balance adjusting device and a self-weight of a grinding body.

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.
