Steering wheel damping apparatus and automobile steering wheel damping system

A steering wheel damping apparatus comprising:

• an elastic member and a sleeve (2), wherein the sleeve (2) has a sleeve portion (21) extending in a main extension direction and an annular supporting portion (22) located at one end of the sleeve portion (21) and extending in a direction perpendicular to the main extension direction;
• the elastic member is molded on the sleeve (2), the part covering the annular supporting portion forms an elastic supporting portion (3), and the part covering the sleeve portion to form an elastic insertion portion (1);
• an elastic rib portion (4) is provided on the elastic insertion portion (1) at an end away from the elastic supporting portion (3);
• the elastic insertion portion (1) between the elastic rib portion (4) and the elastic supporting portion (3) forms a clamping portion (5) having a smaller radial dimension than that of the elastic rib portion (4);
• the elastic insertion portion (1) is configured to pass, in an interference fit manner, through an opening of a member to be mounted;
• the elastic rib portion (4) is configured to be located or abutted on one side of the opening, and the elastic supporting portion (3) is configured to be located or abutted on the other side of the opening;
• and the clamping portion (5) is configured to be embedded in the opening, wherein the elastic insertion portion (1) comprises a plurality of inner ribs (11) recessed inwards from an outer surface of the elastic insertion portion (1) and outer ribs (12) protruding outwards from an inner surface of the elastic insertion portion (1);
• and the inner ribs (11) and the outer ribs (12) arranged in a staggered manner in a circumferential direction of the elastic insertion portion (1).
