How are auto parts front axle assembly parts assembled and adjusted?
Cleaning, inspection and lubrication
The parts should be cleaned before installation, check whether each part in the front axle assembly of the car is free of dirt and damage, and apply a thin layer of engine oil on the mating surface of each part in the front axle assembly of the engine. For automobiles, the bearings should be greased.
Assembly and adjustment of steering knuckle in automobile front axle assembly
①Press the upper and lower bushings of the steering knuckle into the knuckle pin hole, and when pressing the bushes; the oil groove openings on the two bushings should face upwards, and the oil holes of the bushings should be aligned with the nozzle holes on the steering knuckle.
②Insert the right steering knuckle arm and slotted nut into the stud and tighten it, and then lock it with a split pin. Similarly, install the left steering arm.


Detection and adjustment of front wheel alignment and large steering angle of front wheel in automobile front axle assembly
①Detect and adjust the position of the front wheel.
The position of the front wheel in the front axle assembly of an automobile refers to the front wheel camber, kingpin inclination, kingpin caster inclination and front wheel toe angle. Among them, the front wheel camber angle, king pin inclination angle and king pin caster inclination angle are guaranteed by the structural design, and usually do not need to be adjusted during use, while the toes of the front wheel need to be adjusted.
Before detecting and adjusting the position of the front wheel in the front axle assembly of the car, you should confirm that the front wheel hub, king pin (knuckle pin), tie rod ball pin and leaf spring riding bolt are not loose, and the spring in the front axle assembly is not damaged or excessive. Fatigue, tire pressure should meet the standard, and the wheels should be parked on a level field.
②The camber angle of the front wheel in the front axle assembly of the automobile.
Looking at the wheel from the front of the car, the angle at which the upper end of the front wheel tilts outward is called the front wheel camber. Determine when the steering knuckle journal is at an angle to the horizontal during the steering design process. Its purpose is to reduce the resistance moment of the front wheels when turning, and to make the front wheels close to the road and press inward when fully loaded. The tapered bearing makes the front wheel work safely.
