Description
Technical field
The utility model relates to a kind of axle case assy of automotive axle.
Background technology
At present take dual mode to manufacture and design for the junction of axle housing and axle tube: a kind of is to use long solid drawn pipe as axle tube, is pressed into the axle housing two ends, and locatees by pin; Another kind is axle tube and axle housing two ends difference finished edge, links together by the mode of welding.
There is following defective in actual applications in prior art:
When adopting above-mentioned first method, axle tube and axle housing two ends all need to process very long mating surfaces, and need to adopt the press-fit assembling, increase the cost and the assembly difficulty of product; When adopting second method, higher to welding process requirement, need special welding gear, increased the cost of product.Two kinds of methods all are not suitable for the manufacturing of small lot axle case assy
The utility model content
Technical problem to be solved in the utility model provides a kind of beam front axle housing assy, it has the seam of employing boss and cooperates with seam axle housing and axle tube location, utilize bolt that axle housing is connected with axle tube, make connection procedure simple and reliable, can be applicable to the characteristics of the occasion of small lot casting integral axle housing.
For solving the problems of the technologies described above, a kind of beam front axle housing assy that the utility model provides comprises interconnective axle housing and axle tube, it is characterized in that,
The two ends of described axle housing and axle tube connect an end of axle housing, are respectively arranged with the seam and the seam boss that can cooperatively interact;
The two ends of axle housing also are provided with flange, offer bolt hole on the flange;
The end that described axle tube connects axle housing also offers bolt hole, and this bolt hole is corresponding with the flange upper bolt hole of axle housing;
Axle housing cooperates with the seam boss by seam with axle tube and positions, and connects by bolt.
To being improved to of above-mentioned basic design, the end that described axle tube connects axle housing also is provided with flange, is opened on the flange of axle tube with the corresponding bolt hole of flange upper bolt hole of axle housing.
To being optimized for of said structure, the bolt hole rectangular distribution on the flange of described axle housing.
Said structure further is improved to, the propelling rod bearing both sides of the bridge side of wrapping on the axle housing, the vertical mid-plane place that is positioned at axle housing also is provided with reinforced rib, and described reinforced rib extends to the spring bearing place.
Advantage of the present utility model is:
1. axle tube and axle housing are by uniform bolted connection, bonded assembly also has back-plate simultaneously, compare with the axle tube Type of Welding, reduced the welding link, press-fiting form with axle tube compares, reduce axle housing boring (car) hole and axle tube and press-fited link, can cost-cutting and difficulty of processing.
2. by casting reinforcing rib on axle housing, can increase the axle housing load-carrying capacity.
Adopt beam front axle housing assy provided by the utility model, can make the axle case assy processing technology simple, connect reliable, easily assembling, thereby reduced productive costs, can be applicable to the occasion of small lot casting integral axle housing, solve casting integral axle housing at small batch production and adopted other versions to need the problem of special processing equipment, improved the load-carrying capacity of axle case assy simultaneously.In a word, the utility model simple in structure, easy to make, be easy to install, cost is low, easy to operate, result of use is good.
Description of drawings
Below in conjunction with the drawings and specific embodiments the technical solution of the utility model is further described in detail.
Fig. 1 is the utility model structural representation.
Fig. 2 is the general shape scheme drawing of axle case assy.
Wherein, the 1-axle tube, the 2-axle housing, the 3-reinforced rib, the 4-boss, 5-leaf spring end seat connects plane, the flange of 6-axle housing end, 7-seam boss, 8-seam, the mounting flange of 9-axle tube end, 10-back-plate, 11-bolt.
The specific embodiment
Shown in Figure 2 is the overall structure scheme drawing of axle case assy, and as known in the figure, the two ends of axle housing 2 are connected with axle tube 1.Below with reference to structural representation of the present utility model shown in Figure 1, utilize a kind of beam front axle housing assy disclosed in the utility model that axle housing 2 is connected with axle tube 1:
At first, increase reinforced rib 3 on casting rigid axle axle housing, be arranged on the vertical centre plane of axle housing, an end of reinforced rib 3 is connected in the stabilizer rod bearing connection boss 4 that bridge is wrapped side, the other end extends to leaf spring end seat and connects near the plane 5, thereby actv. increases the load-carrying capacity of axle housing.
Next, connection structure to axle housing 2 and axle tube 1 is processed: axle housing 2 adopts inblock cast to be shaped, be provided with flange 6 and seam boss 7 in the both sides of axle housing 1, once finish, can effectively guarantee to install the squareness on seam and flange 6 planes by turning processing.Axle tube 1 adopts the forging mode to be shaped, and a side is provided with seam 8 and flange 9, and processing can be finished by a clamping.
At last, axle housing 2 is connected with axle tube 1: axle housing 2 and axle tube 1 adopt seam boss 7 to cooperate with seam 8 and position, by bolt 11 axle housing 2, axle tube 1 and back-plate 10 are linked together, can finish installation of the present utility model.
