Abstract

The utility model is a kind of automobile front axle, two the I-shape sides comprising front axle body and extend from described front axle body both sides, described side comprises integrated side top, side bottom and connects the connecting portion of described side top and side bottom, described front axle body comprises integrated body upper part and body lower part, described body upper part and side top seamlessly transit, and before and after described body lower part, the parallel and width in two sides is not less than the width of described side bottom.The utility model, by changing car fore axle body structure, is conducive to front axle and absorbs car brakeing inertial impact force and other larger twist moments caused front axle from horizontal direction.

Description

Automobile front axle
Technical field
The utility model relates to automobile front axle manufacturing technology field, and particularly one has larger horizontal torsional strenght automobile front axle.
Background technology
In car load, front axle assy partial brake based part assembly, steering system component assembly as the most crucial parts of front axle assy, and are connected on vehicle body by front axle by front axle.Front axle has bearing automobile weight, to absorb after car brakeing inertial impact force and outer bound pair vehicle other respectively to the effect of application force.
In prior art, the general entire body of front axle adopts i-beam structure, and this structure can carry the application force of vertical direction well, but intensity is in the longitudinal direction less than normal, can not overcome the twist moment in horizontal direction well.And in automobile suspension system, too large lateral inclination is there is when turning in order to prevent vehicle body, rely on propelling rod structure to connect front axle and side suspension, the front end of propelling rod need be installed in the middle part of front axle by thrust bearing, in order to thrust bearing and front axle are fixed, often punch in the middle part of this just very narrow I-beam section, make front axle more be difficult to the twist moment of buffer level.
Therefore, be necessary to provide a kind of new automobile front axle structure to solve the problems referred to above.
Utility model content
Main purpose of the present utility model is to provide one to have larger horizontal torsional strenght automobile front axle.
The utility model is achieved through the following technical solutions above-mentioned purpose: a kind of automobile front axle, two the I-shape sides comprising front axle body and extend from described front axle body both sides, described side comprises integrated side top, side bottom and connects the connecting portion of described side top and side bottom, described front axle body comprises integrated body upper part and body lower part, described body upper part and side top seamlessly transit, and before and after described body lower part, the parallel and width in two sides is not less than the width of described side bottom.
Concrete, described body lower part is provided with the fixed orifice that level runs through.
Concrete, described side top comprises a leaf spring installation portion, and described leaf spring installation portion is wider than described body upper part.
Further, described leaf spring installation portion offers some leaf spring mounting holes vertically running through described side top.
Concrete, described side end is provided with fist shape portion, and described fist shape portion is provided with stub mounting hole.
Concrete, described side upwarps from described front axle body to outer arc.
Adopt technique scheme, the beneficial effect of technical solutions of the utility model is: the utility model, by changing car fore axle body structure, is conducive to front axle and absorbs car brakeing inertial impact force and other larger twist moments caused front axle from horizontal direction.

Detailed description of the invention
Below in conjunction with specific embodiment, the utility model is described in further detail.
As shown in Figures 1 to 4, a kind of automobile front axle of the present utility model, two I-shape sides 2 that the arc comprising front axle body 1 and extend from front axle body 1 both sides upwarps, side 2 comprises integrated side top 21, side bottom 22 and connects the connecting portion 23 of side top 21 and side bottom 22, front axle body 1 comprises integrated body upper part 11 and body lower part 12, side 2 is mainly stressed at vertical direction, in order to alleviate front axle weight, adopts common I-shape construction.Body upper part 11 and side top 21 seamlessly transit, and before and after body lower part 12, the parallel and width in two sides is not less than the width of side bottom 22.Front axle body 1 is a T-shaped structure, and body lower part 12 has certain thickness, more solid bottom relative I-shape construction, is conducive to front axle and absorbs car brakeing inertial impact force and other larger twist moments caused front axle from horizontal direction.Body upper part 11 and side top 21 form an overall holder bearing surface, front axle body 1 and side 2 form an arc structure, not only structural transition is smooth-going, and makes to have larger Area of bearing, dissipation of ferees well between above-mentioned holder bearing surface and automotive parts.
As shown in Figure 1 and Figure 2, body lower part 12 is provided with the fixed orifice 121 that level runs through.These fixed orifices 121 are for installed thrust seat, and because body lower part 12 has larger thickness, the screw of installed thrust seat can deeply be fixed, and avoid body lower part 12 because stress is concentrated produce easy lateral deformation.
As shown in Figure 1, Figure 3, side top 21 comprises a leaf spring installation portion 211, and leaf spring installation portion 211, wider than body upper part 11, leaf spring installation portion 211 offers some leaf spring mounting holes 2111 vertically running through side top 21.Leaf spring mounting hole 2111 on leaf spring installation portion 211 can fixation steel plate spring better, and its structure make use of the I-shape groove shapes of side 2, handled easily.
As shown in Figure 1 and Figure 2, side 2 end is provided with fist shape portion 24, and fist shape portion 24 is provided with stub mounting hole 241.Stub mounting hole 241 fixes steering swivel by stub, realizes the Core Feature of propons.
Above-described is only embodiments more of the present utility model.For the person of ordinary skill of the art, under the prerequisite not departing from the utility model creation design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
