Abstract
The utility model relates to an axle case assembly of an intermediate axle and a rear axle of a trunk or a special vehicle, comprising an axle case and a left-right semi-axle tube, wherein the axle case is a cast-steel axle case and has a structure of a square section, and a reinforcing rib is arranged on the inner wall of the axle tube of the axle case. The utility model enhances the bearing capacity of the axle case and the maneuvering characteristics of vehicles as well. The machining processing technology of the axle case is greatly improved as comparison with that of the original stuffing axle case with a semi-axle tube, and thereby the utility model is beneficial to enhancing the production efficiency and reducing the production cost.
Description
Technical field
The utility model belongs to autotruck or special purpose vehicle axle housing structure technology.
Background technology
Along with development of economic construction, progressively to the large-tonnage development, complete vehicle quality increases the weight of, and requires the load-carrying capacity of vehicle bridge higher for some autotrucies, special vehicle, hoisting crane etc.
Normally the unsprung weight of automobile is big more, the manoevreability of running car is poor more, but the load-carrying capacity of vehicle bridge becomes certain ratio row to concern with the deadweight of vehicle bridge often: meaning is promptly under the material and structure design unmodified situation of vehicle bridge parts, improve load-carrying capacity and can correspondingly increase the vehicle bridge quality, this maneuvering performance index to automobile is unusual adverse factors.
And what extensively adopt in the market is to dash weldering axle housing or inblock cast axle housing, and they all are difficult to solve is improving load-carrying capacity and alleviating the contradiction that exists between the vehicle bridge quality.In addition, existing axle case assy is to adopt press-fit approach to be connected for axle housing and left and right sides axle tube, and the portion size that axle housing and axle tube is press-fited cooperation requires height, crudy assurance ability.
Summary of the invention
The purpose of this utility model is to provide a kind of autotruck jackshaft, rear axle case assembly at the deficiency of prior art existence, not only increases substantially the load-carrying capacity of vehicle bridge, and greatly to the vehicle bridge loss of weight, more helps the raising of vehicle mobility energy.
The technical solution of the utility model is as follows:
A kind of autotruck jackshaft, rear axle case assembly, it comprises axle housing and left and right sides axle tube, and described axle housing is the cast steel axle housing, and axle housing adopts the square section structure, and design has shaft orientation reinforcing rib on the shaft tube inner wall of axle housing; Axle tube adopts the fuse welding to be connected with axle housing.
This axle case assy is owing to adopt the square section structure with axle housing, and designs reinforced rib on shaft tube inner wall, can improve load-carrying capacity to greatest extent; Axle tube and axle housing adopt the fuse welding, can reduce the material usage of axle tube significantly.By applicant's concrete test, this axle case assy can have loss of weight 9.1% on the basis now, but the load-carrying capacity of axle housing improves 20%.Therefore this design plan has also improved the maneuvering performance of car load in the load-carrying capacity that improves axle housing.And the more former axle tube pressing type of the mechanical processing technique condition axle housing of this axle housing has improvement by a relatively large margin, helps enhancing productivity, and reduces production costs.
The technical solution of the utility model be different from fully in the market extensively adopt dash the weldering axle housing, also be different from the inblock cast axle housing, its load-carrying capacity all be better than in the market dash weldering axle housing and inblock cast axle housing, have high cost performance.
Description of drawings
Fig. 1 is the sectional structure chart of this axle case assy:
Fig. 2 is the outside drawing of this axle case assy.
Among the figure 1, axle housing; 2, axle tube; 3, fuse welding region; 4, bottom shaft orientation reinforcing rib
The specific embodiment
Referring to Fig. 1 and Fig. 2, this autotruck jackshaft, rear axle case assembly include axle housing 1 and left and right sides axle tube 2, and wherein axle housing 1 is the cast steel axle housing, and material adopts ZG40Cr, axle housing adopts the square section structure, and the inwall design has bottom shaft orientation reinforcing rib 4 under the central siphon of axle housing.The material that axle tube adopts is 40Cr, is assemblied in the two ends, the left and right sides of axle housing 1, adopts the fuse welding to be connected with axle housing 1, the 3rd, and the fuse welding region.
The product that adopts the technical program to produce, axle case assy weight 220.9Kg, axle housing weight 188.3Kg wherein, axle tube weight 16.08Kg.
By the axle case assy that adopts the utility model organization plan and employing axle tube and axle housing interference pressing type organization plan is done cae analysis, under the on all four situation of boundary condition, adopt the utility model organization plan to improve significantly than the distribution of stress of interference press mounting structure scheme, same bearing capacity, identical constraint condition, the former maximum stress 586Mpa, latter's maximum stress 510Mpa, settle accounts on the load-carrying capacity of axle housing, the axle housing load-carrying capacity after the optimization has improved nearly 20%.
