Anti-friction pad for a bushed pivot point connection of a main leaf
spring and a secondary leaf spring
摘要:
An anti-friction pad for a bushed pivot connection of a main leaf spring and a secondary leaf spring of a spring mounted air spring suspension of a vehicle. The pivot connection includes a bushing, a main leaf spring having an eye receiving the bushing and a secondary leaf spring having an eye receiving the eye of the main leaf spring and the inside surfaces of bushing hanger bracket. The anti-friction pad has an elongated main body portion positioned between and in contact with the main leaf spring and the secondary leaf spring. The anti-friction pad also has side walls which engage the secondary leaf spring. The anti-friction pad has a center post which seats in a socket of the secondary leaf spring. The main body portion of the pad has an outer convex surface which mates with a concave face of the main leaf spring. The anti-friction pad is formed of an ultra high molecular weight polyethylene.
