Abstract

A knuckle assembly for use with a wheel suspension system of a vehicle, having a knuckle configured to mount a wheel thereto, and having a knuckle body comprising upper and lower abutting surfaces, and an upper and a lower vertical bore portion extending inwardly from the abutting surface. The upper and lower vertical bore portions constitute a portion of a single through-bore extending between the upper and lower abutting surfaces. The knuckle assembly has upper and lower steering axles, each having an inner steering axle portion fixedly received within a respective vertical bore portion and an outer steering axle portion protruding from the respective abutting surfaces. The upper and lower steering axles constitute respective upper and lower portions of a common steering axle. The knuckle assembly also has upper and lower spacing members, each made from a low-friction material and being in contact with the respective abutting surface. Each spacing member has a flanged portion surrounding the outer portion of the corresponding axle and an in-bore received portion, snuggly fitted within corresponding vertical bore portion and surrounding the inner portion of the corresponding axle. Also, the knuckle assembly has upper and lower joints configured for connecting thereto a knuckle engaging end of a suspension arm so as to allow the arm to pivot thereabout. Each joint contacts the corresponding spacing member that distance it from the corresponding abutting surface and freely receiving the outer portion of the corresponding steering axle, so as to allow the knuckle, together with the axle, to pivot between the two joints only about the vertical knuckle axis which maintains its position and orientation relative to the joints.
