Abstract
A pin bush for connecting linkages, comprising: a spheroid member; a metal pin for connecting the pin bush to a linkage, the metal pin extending through the spheroid member forming together a spheroid pin member; a metal sleeve enclosing the spheroid pin member; and a rubber lining arranged between the metal sleeve and the spheroid pin member, the rubber lining being configured to reduce vibrational energy transfer between the metal sleeve and the spheroid pin member, wherein the spheroid member is a plastic member.
Claims21
A pin bush for connecting linkages, comprising:
- a spheroid member;
- a metal pin for connecting the pin bush to a linkage, the metal pin extending through the spheroid member forming together a spheroid pin member;
- a metal sleeve enclosing the spheroid pin member;
- and
- a rubber lining arranged between the metal sleeve and the spheroid pin member, the rubber lining being configured to reduce vibrational energy transfer between the metal sleeve and the spheroid pin member, wherein the spheroid member is a plastic member.
A method of forming a pin bush for connecting linkages, comprising:
- providing a spheroid member made of a plastic material;
- providing a metal pin;
- pressing the metal pin into a through hole of the spheroid member;
- providing the spheroid member comprising the metal pin with a rubber lining;
- and
- providing an outer metal sleeve onto the rubber lining.
A method of forming a pin bush for connecting linkages, comprising:
- providing a metal pin;
- molding a spheroid member from a plastic material around the metal pin such that the metal pin extends through the molded spheroid member;
- providing the spheroid member comprising the metal pin with a rubber lining;
- and
- providing an outer metal sleeve onto the rubber lining.
