Abstract
The utility model proposes a kind of duplexing word to cut section bar Integral steering Drive axle housing, described axle housing comprises axle housing, spindle nose, leaf spring holder and bonnet; Spindle nose is formed at the end of axle housing respectively; Bonnet is formed at the middle part of axle housing; Leaf spring holder is formed at bonnet both sides respectively.The duplexing word of technical solutions of the utility model cuts section bar Integral steering Drive axle housing, the spindle nose at axle housing two ends, bonnet and axle housing are cast as an entirety, ensure that the rigidity of axle housing entirety, lightweight, compact conformation, reduce parts kind, reduce welding or the assembly manufacturing of spindle nose part; Casting Axle Housing Design is twin I-beam structure, substantially increases the rigidity of support of axle housing; Under axle housing, eccentric design, increases axle housing load-carrying capacity, makes distribution of stress even; Axle housing adopts variable section not wait wall thickness design, and average stress distributes; Lower plate holder place of leaf spring holder is designed to great transition circular arc, plane of weakness place stress decrease, long service life.
Description
Technical field
The utility model relates to motor turning drive axle technical field, especially relates to a kind of duplexing word and to cut section bar Integral steering Drive axle housing.
Background technology
Steering drive axle axle housing is one of main parts size on automobile.Axle housing plays a part to support automobile load, and load is passed to wheel.Tractive force, braking force, side power, side force and the vertical force acted on driving wheel is also through axle housing and passes on suspension, vehicle frame or compartment.Therefore axle housing is load member and force transmission element.When automobile in the process of moving, bear heavy load, especially when automobile is by uneven road surface, all higher requirement can be had to the carrying of steering drive axle and crossing ability, spindle nose and the axle housing of existing steering drive axle axle housing mostly are welding process, due to the impact load that wheel and ground produce, when designing improper or manufacturing process and having problem, axle housing can be caused to be out of shape or to fracture, therefore must consider that axle housing has enough strength and stiffness when designing.The blank area of tradition spindle nose is connected with axle housing by welding or bolt, is unfavorable for that axle housing entirety is fallen heavily.
Utility model content
The utility model proposes a kind of duplexing word to cut section bar Integral steering Drive axle housing, lightweight, compact conformation, the basis of original axle housing adds rigidity of support and intensity; Casting Axle Housing Design is twin I-beam structure, substantially increases the rigidity of support of axle housing; Under axle housing, eccentric design, increases axle housing load-carrying capacity, makes distribution of stress even.The prior art solved is, in vehicle traveling process, due to the impact load that wheel and ground produce, cause axle housing distortion or fracture, the technical matters such as rigidity is weak, load-carrying capacity is low, understressing.
The technical solution of the utility model is achieved in that
A kind of duplexing word cuts section bar Integral steering Drive axle housing, comprising: axle housing, two spindle noses, two leaf spring holders and bonnets; Described two spindle noses are arranged at the end of axle housing respectively; Described bonnet is arranged at the middle part of axle housing; Described two leaf spring holders are arranged at bonnet both sides respectively; The spindle nose at described axle housing two ends, bonnet and axle housing are cast into one, and it is characterized in that, the cross section of described axle housing is twin I-beam structure, and the relative axle housing centre portion of spindle nose line of centers at described axle housing two ends and bonnet center offset downward.
Further illustrate, the lower plate holder both sides of leaf spring holder are great transition circular arc, and lower plate holder and axle housing are cast into one by great transition circular arc.
Further illustrate, leaf spring holder comprises upper plate holder and lower plate holder, and upper plate restitope is directly over lower plate holder.
Further illustrate, axle housing also comprises upper wall and lower wall again, and wall thickness is greater than wall thickness above below.
Technical solutions of the utility model, by the spindle nose part at axle housing two ends, bonnet and axle housing are cast as an entirety, ensure that the rigidity of axle housing entirety, lightweight, compact conformation, reduce parts kind, reduce welding or the assembly manufacturing of spindle nose part; Casting Axle Housing Design is twin I-beam structure, substantially increases the supporting rigidity of axle housing; Under axle housing, eccentric design, increases axle housing load-carrying capacity, makes distribution of stress even; Axle housing adopts variable section not wait wall thickness design, and average stress distributes; Leaf spring holder place great transition designed arc-shaped appearance, plane of weakness place stress decrease, long service life.
Accompanying drawing explanation
Fig. 1 is that duplexing word cuts section bar Integral steering Drive axle housing structural representation.
Fig. 2 is axle housing cross section twin I-beam constructional drawing.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, the utility model is described in detail.
Integral steering Drive axle housing of the present utility model is positioned at steering drive axle outside, coordinates steering drive axle to use.
See accompanying drawing 1, a kind of duplexing word cuts section bar Integral steering Drive axle housing, and it is cast into one by the spindle nose 2 at axle housing 1, axle housing two ends with bonnet 3, makes Drive axle housing compact overall structure, weight saving, ensure that the rigidity of axle housing.Axle housing adopts variable section not wait wall thickness design, and the upper wall 6 of axle housing is different from lower wall 7 thickness, and average stress distributes.
See accompanying drawing 2, Casting Axle Housing Design is that duplexing word cuts section bar structure 8, substantially increases the rigidity of support of axle housing; Eccentric design under axle housing, the relative axle housing centre portion of spindle nose line of centers at axle housing two ends and bonnet center offset downward, and increase axle housing load-carrying capacity, make distribution of stress even; Leaf spring holder comprises upper plate holder 4 and lower plate holder 5, and lower plate holder 5 place is designed to great transition circular arc, plane of weakness place stress decrease, long service life.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
Claims (3)
1. duplexing word cuts section bar an Integral steering Drive axle housing, comprising: axle housing, two spindle noses, two leaf spring holders and bonnets; Described two spindle noses are arranged at the end of axle housing respectively; Described bonnet is arranged at the middle part of axle housing; Described two leaf spring holders are arranged at bonnet both sides respectively; The spindle nose at described axle housing two ends, bonnet and axle housing are cast into one, and it is characterized in that, the cross section of described axle housing is twin I-beam structure, and the relative axle housing centre portion of spindle nose line of centers at described axle housing two ends and bonnet center offset downward; The lower plate holder both sides of described leaf spring holder are great transition circular arc, and lower plate holder and axle housing are cast into one by great transition circular arc.
