Abstract
The utility model discloses a knuckle assembly with a blind hole at one end, which belongs to the technical field of automobile axles, and adopts a coaxial through hole and blind hole structure, and the blind hole is used for being filled with an upper bushing and an upper oil seal; the through hole is used for installing the lower bushing and the lower oil seal; the end face of the blind hole adopts a threaded hole structure and is used for installing a nozzle tip; the lower end face of the through hole adopts two distributed threaded holes for connecting the end cover through bolts. Compared with the traditional through hole structure, the steering knuckle assembly of the utility model reduces the upper end cover structure, the connecting bolt structure and the material cost; the steering knuckle reduces the processing of the upper end surface and the threaded holes on the end surface, and reduces the processing cost; the assembling process of the upper end cover is reduced, and the assembling cost is reduced.
Description
Technical Field
The utility model belongs to the technical field of the car axle, concretely relates to knuckle assembly of one end blind hole.
Background
In a domestic automobile steering axle, two main pin holes of a steering knuckle adopt a through hole structure, and in the structure, blocking cover structures are required to be arranged at two ends of the steering knuckle, so that the material cost of the blocking covers is increased; increase the material cost of the connecting bolt; the processing cost of the end surface and the threaded hole of the steering knuckle is increased; increasing the assembly cost of the end cap.
SUMMERY OF THE UTILITY MODEL
In order to solve current car steering axle, because two king-pin holes of knuckle all adopt the through-hole structure to seal with the blanking cover, lead to the material cost increase of blanking cover, connecting bolt's material cost increase, the processing cost increase of knuckle and the assembly cost increase scheduling problem of end cover, the utility model provides a knuckle assembly of one end blind hole, reduce cost promotes assembly efficiency.
The utility model discloses a following technical scheme realizes:
a knuckle assembly with a blind hole at one end comprises a knuckle shaft 15, an upper steering support 16, a lower steering support 17 and an upper oil nozzle 7; the steering knuckle spindle 15 is respectively connected with an upper steering support 16 and a lower steering support 17 through a connecting plate, a blind hole is formed in the upper end of the upper steering support 16, a through hole is formed in the lower steering support 17, the blind hole and the through hole are coaxial, an upper bushing 8 is arranged on the inner wall of the blind hole, the lower end face of the upper bushing 8 is aligned with the end face of the blind hole, and an upper oil seal 9 is arranged on the end face of the blind hole; a lower bushing 11 is arranged on the inner wall of the through hole, the end face of the lower bushing 11 is aligned with the end face of the through hole, a lower oil seal 10 is arranged on the upper end face of the through hole, and a threaded hole is formed in the lower end face of the through hole and used for being connected with an end cover 5; the upper oil nozzle 7 penetrates through a blind hole of the upper steering support 16.
Compared with the prior art, the utility model has the advantages as follows:
the steering knuckle structure with the blind hole at one end adopts the blind hole structure through the upper main pin hole of the steering knuckle, and compared with the traditional through hole structure, the structure of the upper end cover is reduced, the structure of the connecting bolt is reduced, and the material cost is saved; the steering knuckle reduces the processing of the upper end surface and the threaded holes on the end surface, and reduces the processing cost; the assembling process of the upper end cover is reduced, and the assembling cost is reduced.
