·200· Sn Description Data 7 Lubricant volume (L) 0.4 8 Power assisted steering fluid ATFⅢ automatic transmission fluid Q/SH038.501 9 Torque of track bar front end nut (N.m) 120.5±5 10 Tightening torque of cam nut (N.m) 200±8 11 Tightening torque of steering tie-rod locknut (N.m) 88±4 12 Tightening torque of ball joint of steering knuckle arm and tie-rod (N.m) 73.5~108 13 Maximum tangential force of steerer wheel <200 14 Driving deviation When driving straight along center line of test track at 40km/h for 30m, the left deviation<2m while the right <1m (steering wheel is released). 15 Minimum turning radius (m) 5.75 Vehicle in driving needs to change direction (steering) often. Driver turns wheels (steered wheels) to an angle with vehicle longitudinal axial line via steering axle (usually front axle). Beside, vehicle driving straight line are often subjected to side interference on its steered wheels from road. The force makes steered wheels swinging to change driving direction. Driver can turn steered wheel to reverse direction then, returning vehicle to its original driving direction.
Steering system is composed mainly by steering operating mechanism, steering gear and steering driving mechanism. Steering operating mechanism consists of steering wheel, steering spindle and steering column. Steering gear changes steering wheel’s rotation into steering arm’s swing, and amplify steering operating force. BJ6536 vehicle adopts ball rack and pinion steering gear with a ratio of 46.67. It has two stage driving sets: the first stage is screw and nut driving sets, and second stage is rack and pinion driving sets. Steering mechanism transmits output from steering gear to knuckle, turning wheels according to certain arrangement. The mechanism consists of steering arm, drag link, tie rod and knuckle arm.
