[0002] The control arm of a car is a guide and force transmission element of the car suspension system. The car control panel includes a bushing, which is an important component in the car shock absorption system. It not only needs to meet the requirements of the three-axial, torsional and other dynamic and static strength characteristics of general car parts, but the currently used car control arm bushing has a rubber sleeve sandwiched between an outer sleeve and an inner sleeve, which exposes both ends of the rubber sleeve to the air. With long-term use and contact with the air, the rubber sleeve is indirectly aged rapidly, and the service life of the rubber sleeve is reduced. This results in the need to replace the bushing regularly, thereby increasing the cost of use.
