Abstract
The utility model discloses an expanding axle housing in truck bridge is whole, including axle housing body and central siphon, the central siphon includes the extrusion axis head, pushes away square shaft pipe portion, push away the square shaft pipe connect squeeze of portion spindle nose portion and axle housing body, the extrusion axis head, to push away square shaft pipe portion, axle housing body be by the whole shaping of pipe blank. The utility model discloses a monolithic structure is made by pipe blank extrusion, heat expansion shaping, and material utilization rate is showing than punching press welding process and improves to can cancel welder's die -filling utensil. Compare with casting formula axle housing and more have the advantage that the finished piece quality is light, the rigidity sufficient, intensity is good, reduced the machining volume, save raw and other materials.
Description
Technical field
The utility model belongs to truck vehicle bridge technical field, and more particularly, it relates to a kind of truck bridge entirety internal-expansion type axle housing.
Background technology
At present, the driving axle housing of automobile can be divided into cast type axle housing and punching welding type axle housing, and cast type axle housing system adopts spheroidal graphite cast-iron or high-strength cast iron monoblock cast to go out the hollow pipe chaeta base of central Chinese lute shape shedding shell and both sides variable cross-section. After to its machining, then its two ends are pressed into longer axle tube, and fix with bolt or bearing pin. Cast type axle housing high material consumption, follow-up machining amount is large, is difficult for realizing near-net-shape and lightweight, fast manufactures. Punching welding type axle housing adopts low-carbon alloy steel thick plate to make raw material, through blanking, bending operation, strikes out respectively after first axle housing body, second axle housing body, then the two assembly welding is become to axle housing with CO2 gas shielded arc welding. Punching welding type axle housing production equipment is many, and moulds of industrial equipment are many, and investment is large, due to welding deformation, can cause axle housing anti-fatigue performance to reduce.
Utility model content
The truck bridge entirety internal-expansion type axle housing that the purpose of this utility model is to provide that a kind of novel structure, intensity are high, adequate rigidity, bearing capacity are large, save raw material, technique is simple, moulds of industrial equipment consumption is few, to overcome existing deficiency in prior art.
The technical scheme in the invention for solving the technical problem is: truck bridge entirety internal-expansion type axle housing, comprise axle housing and central siphon, described central siphon comprises extrusion axis head, pushes away square shaft pipe portion, the described square shaft pipe portion that pushes away connects extrusion axis head and axle housing, described extrusion axis head, pushes away square shaft pipe portion, axle housing by pipe blank global formation.
Described axle housing is prepared by preheating forming by internal expansion.
The cross section of described extrusion axis head is circular, described in push away square shaft pipe portion cross section be square or rectangle.
The thickness range of the shaft shoulder wall thickness H of described extrusion axis head is 25-30mm.
The shaft shoulder wall thickness H of described extrusion axis head is 28mm.
The beneficial effects of the utility model are:
The utility model is monolithic construction, is made by the extruding of pipe blank, billow forming, and stock utilization significantly improves than punch welding technique, and can cancel welding tooling mould. Have more compared with cast type axle housing that parts quality is light, adequate rigidity, advantage that intensity is good, reduced machining amount, save raw material.
