Abstract
The technical scheme that the utility model adopts is as follows: a split eccentric variable cross section cast iron axle housing is provided, the outline of the longitudinal cross section of the inner cavity of the axle housing is in an eccentric square shape, and shaft tubes on both ends are provided with step-shaped bosses. Consequently, when the housing body bears load from directions, the strength and rigidity are enhanced, and high bearing performance is achieved.
Description
Technical field
The utility model relates to a kind of cast iron axle housing, is specifically related to a kind of split centering type variable section cast iron axle housing.
Background technology
Driving axle housing is one of main parts size on the automobile, and axle housing plays a part the loading of supporting automobile, and load is passed to wheel.The tractive force, braking force, side power, side force and the vertical force that act on the drive wheels also are to pass on suspension and vehicle frame or the compartment through axle housing.Therefore, axle housing promptly is that load member is again a force transmission element.When automobile in the process of moving, bear heavy load, especially when automobile passes through uneven road surface, because the impact load that wheel and ground are produced, when the improper or manufacturing process of design has problem, can cause axle housing distortion or fracture, therefore when design, must consider that axle housing has enough strength and stiffness.
The utility model content
At the deficiency that prior art exists, technical problem to be solved in the utility model is that a kind of split centering type variable section cast iron axle housing is provided, make housing when bearing the load of coming everywhere, stress can rectangular distribution everywhere, strengthens intensity and rigidity, reaches the performance of high-mechanic.
For solving the problems of the technologies described above, technical solution adopted in the utility model is, a kind of split centering type variable section cast iron axle housing, the outline of its axle housing inner chamber vertical section are eccentric square, and the central siphon at two ends is provided with the step boss.
Above-mentioned split centering type variable section cast iron axle housing, the wall thickness 10mm of its axle housing bonnet place, the wall thickness 16mm of bridge bag place, following circular arc wall thickness 21mm, last circular arc wall thickness 16mm, the wall thickness 29mm of biside plate spring abutment place.
The utility model is under the prerequisite that does not increase weight, and with axle housing cross section remodeling, it is square to change off-centre into by original circle, axle housing transition position great circle arc rounding off.And whole housing does not wait wall thickness change, makes housing when bearing the load of coming everywhere, and stress can rectangular distribution everywhere, has strengthened intensity and rigidity, makes it reach the performance of high-mechanic.
Description of drawings
Below in conjunction with accompanying drawing and example the utility model is further described.
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in the figure, split centering type variable section cast iron axle housing of the present utility model, the outline of its axle housing inner chamber 1 vertical section are eccentric square, and the central siphon 2 at two ends is provided with step boss 21.Its axle housing bonnet 3 wall thickness 10mm of place, the bridge bag 4 wall thickness 16mm of place, following circular arc 5 wall thickness 21mm, last circular arc 6 wall thickness 16mm, the biside plate spring abutment 7 wall thickness 29mm of place.
The above, only be to preferred embodiment of the present utility model, be not to be that the utility model is done other forms of restriction, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the equivalent embodiment of equivalent variations.But every technical solutions of the utility model content that do not break away to any simple modification, equivalent variations and remodeling that above embodiment did, still belongs to the protection domain of technical solutions of the utility model according to technical spirit of the present utility model.
Claims (2)
