STEERING KNUCKLE

摘要

A vehicle steering knuckle assembly (304) for use in association with a vehicle steering axle assembly (305) is shown to include an upper piece (306) having a first king pin bore (316) extending through it and a backbone piece (308) removably connected to the first piece (306). The backbone (308) has a second king pin bore extending through it. The upper piece (306) has an integral steering arm (310) and a pad (312) through which is machined a steering ball taper. The lower piece (308) has an integral tie rod (330) and a pad (332) through which is machined a tie rod ball taper. Because the two pieces are removable from each other, the steering knuckle can be assembled and serviced while a king pin is retained in place in an axle beam.
