Detailed Description
The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.
The embodiment provides a knuckle shell subassembly, through carrying out structural improvement to the knuckle shell wherein, can reach and reduce part kind and quantity for overall structure is simple, spatial arrangement is succinct compact, assembles the good effect of manufacturability simultaneously.
Specifically, referring to fig. 1 to 5, the knuckle housing assembly proposed in the present solution includes a left knuckle assembly 10 and a right knuckle assembly 20.
The left steering knuckle assembly 10 comprises a left steering knuckle shell 11 and a straight pull rod arm 12, wherein the straight pull rod arm 12 is fixed with the left steering knuckle shell 11 through a connecting bolt 13; there are first connecting plates 14 on the end face of the bottom and the end face of the top of the left knuckle case 11, the first connecting plates 14 are integrally formed with the left knuckle case 11, and each first connecting plate 14 is provided with a plurality of first connecting holes.
The right knuckle assembly 20 includes a right knuckle case 21, and second connection plates 22 are provided on end surfaces of a bottom and a top of the right knuckle case 21, the second connection plates 22 being integrally formed with the right knuckle case 21, and a plurality of second connection holes being provided on each of the second connection plates 22.
The first connecting plate 14 and the second connecting plate 22 can be understood as the connecting plates of the brake in the prior art, and are used for fixedly mounting the brake. The left and right steering knuckle shells and the brake connecting plate (the first connecting plate and the second connecting plate) are integrally cast and molded, so that the number of parts is obviously reduced, the light weight of the parts is realized, and the complexity of operation is reduced; compared with the conventional mode of fixing a single part, the mode of integral casting has obvious improvement on the integral strength and stability.
Of course, the connection holes of the first and second connection plates 14 and 22 need to correspond to the holes of the brake to achieve stable mounting with the brake. Optionally, the number of the first connecting holes and the number of the second connecting holes are not less than five, that is, the number of the connecting holes is only large, but not small.
Meanwhile, the steering knuckle shell of the steering drive axle and the front axle steering knuckle are in the same structure, and an integral main pin hole is generally adopted, namely the main pin hole is directly formed in the steering knuckle shell, so that a press-fitting process is required when related parts such as a main pin, a supporting seat and the like are assembled, the assembly is easy to realize and the assembly is difficult, the later-stage disassembly maintenance is also difficult, and the press-fitting manufacturability is not ideal; in this regard, we have also improved the structure of the king pin hole.
In the scheme, a first half edge end cover 111 is arranged at the position of the left steering knuckle shell 11 opposite to the drag link arm 12; a second half end cover 121 is arranged at the position of the straight pull rod arm 12 opposite to the left steering knuckle shell 11; the first half end cover 111 and the second half end cover 121 are fixed by the connecting bolt 13 to form the upper left king pin hole 1 a.
It can be understood that the upper king pin hole 1a of the left knuckle shell 11 is assembled by two separate parts, namely, the left knuckle shell 11 with the first half end cap 111 and the straight pull rod arm 12 with the second half end cap 121, and the two half end caps are assembled together to form the end cap with the upper king pin hole 1 a. The split type design is carried out on the upper main pin hole 1a, when relevant parts such as a main pin and a supporting seat are assembled, the traditional press fitting process is not needed, the mounting difficulty is effectively reduced, meanwhile, the split type design is also beneficial to later-stage disassembly and maintenance, and the manufacturability of secondary assembly is good.
Similarly, the right knuckle assembly 20 further comprises a fourth half end cap 23; a third half end cover 211 is arranged at the far end of the right knuckle shell 21, and the fourth half end cover 23 and the third half end cover 211 are fixed by a fastening bolt 24 to form a right upper main pin hole 2 a. The upper right king pin hole 2a is designed as a split structure and functions as the upper king pin hole of the left knuckle housing 11, and the detailed description thereof is omitted.
In the scheme, the left steering knuckle shell 11 and the right steering knuckle shell 21 are provided with lower king pin holes 1b and 2b for mounting lower king pins; while the lower king pin hole is configured to be able to mount the thrust bearing 30 and to have a gap L between the thrust bearing 30 and the lower king pin hole. The thrust bearing 30 is guaranteed to freely enter the assembly position during assembly, and convenient disassembly during aftermarket maintenance is achieved.
In the technical scheme, the left and right steering knuckle shells and the brake connecting plates (the first connecting plate and the second connecting plate) are integrally formed, and compared with the existing steering knuckle shells and the brake connecting plates through bolt connection, the type and the number of parts are reduced, so that the overall structure is simple, the spatial arrangement is simple and compact, and the assembling manufacturability is good. Meanwhile, the upper left main pin hole and the upper right main pin hole are of split structures, so that the process assembly performance is enhanced, the post-market maintenance is simple, and the split structure is suitable for various main pin structures such as a bushing, a roller pin, a mixed roller pin and the like.
The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
