Housing is a installation base for final drive, differential, semi-shaft, hub, suspension and so on. Its main function is protecting final drive, differential, semi-shaft, meanwhile, it’s a main part in driving system to support vehicle weight and transfer force.
Toe-in can be adjusted by adjusting length of tie-rod.

Kingpin Inclination
Function: 1. maintain straight running stability, make steering wheel automatically return to ahead direction 2. Make steering operation easier. 5º -8º
Axle Housing
Function: Accept power from transmission shaft, reduce speed and increase torque value, change power transmit direction.

Tie-rod Arm
Tie-rod arm is a kind of forge piece, and connected with steering knuckle through bolts. It make sure inner and outer wheels turn around the same centre of a circle, reduce tire wearing.

Clearance Adjustment Arm
To adjust brake clearance, we can adjust the worm hex-head. We have manual and automatic, two kinds of adjustment arm.

Tie-rod is normally a cold drawing steel tube, it’s two ends connected with steering knuckle arms, form a steering trapezoid, to realize two sides wheel turning at the same time and around the same centre of cycle.
Forge piece, the cervical part need be quenched. It turn around king pin to achieve steering motion. Bearings are installed on journal, wheel hub rotate around bearing to achieve go forward and backward.

One end of Drag link arm is fixed on steering knuckle by bolts, another connect with drag link, it’s function is transfer torque to steering knuckle. Normally it’s installed on left knuckle.

I-beam, forging part, its main function is supporting vehicle weight, the section normally is “I” shape. This can be less weight, large rigidity and strength. Main design parameter: leaf spring centre distance, kingpin centre distance, section size, and kingpin angle.

Driving Axle
Function: Accept power from transmission shaft, reduce speed and increase torque value, change power transmit direction, then pass to driving wheels, realize both sides wheels turning at different speed. Constitution of driving axle: Housing —final drive and differential installation base. Final drive —reduce speed, increase torque value, change power transfer direction. Differential —ensure two sides wheels turning at different speed to fit various road. Semi axle —transfer torque from differential to wheels
