A damper bumper cap for covering the rod side end of the damper tube containing a piston rod seal and for retaining a dust cover on the damper tube. The cap includes a side wall positioned in contact with the damper tube, an end wall that extends radially inwardly over the piston rod seal, and an annular skirt that is spaced radially outward of the side wall. First and second groups of connection wall segments extend radially between the side wall and the annular skirt at different heights to define vent openings in the spaces between the connection wall segments in the first and second groups of connection wall segments. The vent openings thus provide a plurality of tortuous airflow paths through the cap at circumferentially spaced locations.

A vibration damping component, comprising a hydraulic cylinder and a hydraulic motor. The hydraulic oil cylinder comprises an oil storage cylinder and a working cylinder, wherein the working cylinder is internally provided with a first piston piece and is divided into an expansion cavity and a contraction cavity by means of the first piston piece; the expansion connects the oil storage cylinder by means of a first one-way oil discharge; the contraction connects the oil storage cylinder by means of a second one-way oil discharge; the oil storage cylinder is provided thereon with an oil outlet hole; an input end of the hydraulic motor is connected to the oil outlet hole; and an output end of the hydraulic motor is in communication respectively with the expansion by means of a first one-way oil return pipe and with the contraction by means of a second one-way oil return pipe.

A shielding element for protecting at least one suspension and/or driveline component. The shielding element is connected to a suspension component. The suspension component extends in a first axial direction and includes a mounting portion at one end for mounting the suspension component to a vehicle. The suspension component further includes a second end for mounting the suspension component to a knuckle. The second mounting portion is capable of receiving a suspension mounting component, which may be or include a ball joint. The shielding element is located near the second mounting portion. The shielding element extends from a surface of the suspension component in a second direction different from the first direction. The portion of the protection element that extends in the second direction may protect at least one of the mounting point, the suspension mounting component, and the driveline component from contact with debris.
