3.1.7 Steering knuckle
The steering knuckle is one of the important parts of the steering axle, and its
connection on the steering axle see Fig. 3-7. The axial clearance of the two bearings
connected with the hub can be adjusted by a round nut for the axial fixing of the bearing. The
main pin and the steering knuckle assembly can be joined by tightening screws and rotate
together with the steering knuckle assembly. Axial clearance of hub bearing in steering
knuckle assembly has been adjusted before the whole vehicle leaves the factory. Unless there
are other special circumstances, please do not adjust bearing clearance at will, such improper
adjustment of bearing clearance will directly affect the service life of bearings. In order to
ensure your normal use, please regularly add enough grease to the bearing chamber of the
hub.
