The main element of the front suspension is a hydraulic telescopic shock absorber strut 8 (pic. 6.1), the lower part of which is connected to the steering knuckle 13 with two bolts 11 and 12. The upper bolt 11, passing through the oval hole of the rack bracket, has an eccentric belt and an eccentric washer. Turning the top bolt changes the camber of the front wheel.
A twisted conical spring 6, a polyurethane foam buffer 22 of the compression stroke and an upper support 3 of the strut assembly with a bearing 4 are installed on the telescopic strut. The upper support is attached with three self-locking nuts to the body mudguard strut. Due to its elasticity, the support provides «rocking» struts during suspension travel and dampens high-frequency vibrations. The bearing built into it allows the rack to turn along with the steered wheels. Details of a hydraulic telescopic shock absorber are mounted in the rack housing.
The lower part of the steering knuckle is connected by a ball joint 18 to the lower suspension arm 17. Braking and traction forces are perceived by longitudinal extensions 16, which are connected through silent blocks to the lower levers and front supports of the front suspension cross member. Adjusting washers are installed at the connection points of the extension with the lever and the front support, which regulate the angle of the longitudinal inclination of the axis of rotation. In the steering knuckle 13, a double-row closed-type angular contact bearing is mounted, on the inner rings of which the wheel hub 19 is installed with an interference fit. The bearing is tightened with a nut 20 on the shank of the outer hinge housing of the wheel drive and is not adjustable. All nuts for fastening the front and rear wheel hubs are the same, and have a right-hand thread.
The anti-roll bar is a bar 15, the knees of which are connected to the lower suspension arms 17 through racks with rubber hinges and silent blocks. Medium (torsion) part of the rod is attached to the body with brackets through rubber cushions.
