Passenger right front loaded steering knuckle assembly is a high-strength steering knuckle assembly. When the car is running, it is subjected to variable shock loads. The utility model is characterized in that an axially extending groove is provided on the inner circumferential surface of the sleeve, the groove starts from one end surface of the sleeve and ends at a certain distance between the inner circumferential surface of the sleeve and the other end surface.
The passenger right front loaded steering knuckle assembly includes:
1. Knuckle with mounting holes.
2. The king pin placed in the steering knuckle mounting hole.
3. A sleeve arranged between the steering knuckle and the king pin and capable of supporting the relative rotation of the steering knuckle and the king pin.
4. An oil storage hole is provided on one end of the main pin.
Compared with the existing steering knuckle assembly, the utility model processes spiral grooves on the inner circumferential surface of the sleeve, which has the advantage of being simpler than the process of processing oil storage points; in addition, there is no need to open an opening on the circumferential surface of the king pin, which effectively ensures the strength of the king pin and eliminates the hidden safety hazards of the passenger right steering knuckle assembly.
When assembling the steering worm and nut assembly, first put the steering nut on the steering worm, place the nut on one end of the worm raceway and align the nut raceway hole with the raceway, and then put the steel ball into the nut raceway hole, While rotating the worm, insert the steel ball (two races can be carried out at the same time, apply a small amount of grease to both ends of the pipe and insert it into the pipe hole of the nut; at the same time, tap the pipe lightly with a wooden hammer to make it fall to the bottom; then use The pipe clamp presses the pipe on the nut and fastens it with screws. After the steel ball is installed, turn the worm by hand to ensure that the nut rotates flexibly within the full length of the worm raceway and does not get stuck. When the worm and nut assembly are in a vertical position At the same time, the nut should be able to fall freely and uniformly from the upper end of the worm. Finally, press the outer ring of the centripetal thrust ball bearing into the bottom cover and the housing, and at the same time, press the bearing inner ring assembly to both ends of the steering worm.
The assembly of steering worm, nut assembly and housing. Put the worm and nut assembly with the bearing inner ring into the shell with the bearing outer ring, then install the bottom cover with the bearing outer ring on the shell and press it by hand while using a thickness gauge or caliper Measure the gap between the bottom cover and the shell, select a set of adjustment gaskets with the same thickness as the gap, remove the bottom cover, apply sealant on the gasket, and put on the 0-shaped rubber sealing ring, and then the bottom The cover is mounted on the shell and fastened with bolts. After assembly, the worm should rotate freely and there is no feeling of axial clearance.
Assembly of steering gear. The recirculating ball steering gear, as one of best steering knuckle parts is equipped with steel balls in the raceway formed by the steering worm and the steering nut. When installing the steel balls in the nut guide groove, a little grease should be applied to both ends of the guide to prevent the steel balls from falling out.
