Abstract
The utility model discloses a framework of an automobile steering support assembly. The framework of the automobile steering support assembly comprises a cross beam, a left side-wall connecting support, a right side-wall connecting support, a front wallboard connecting support, a lower floor connecting support and a small installation support. The cross beam, the left side-wall connecting support, the right side-wall connecting support, the front wallboard panel connecting support, the lower floor connecting support and the small installation support are integrally formed in a die-cast mode. The framework of the automobile steering support assembly solves the technical problems that the assembly technological process of an existing framework of a steering support assembly is complicated, and the damping performance and the size stability are poor.
Description
Technical field
The utility model relates to the parts of automobile, more specifically to a kind of automobile steering supporting assembly skeleton.
Background technology
Automobile steering supporting assembly is positioned at the front bottom of driving compartment, is made up of center framework transverse tube and accessory holder thereof.Existing steering support assembly skeleton mainly adopts steel structure; as shown in Figure 6; form main body by transverse tube 11, left side connection bracket 12, right side connection bracket 13, lower floor connection bracket 14, forearm plate connection bracket 15, connect left/right-body, lower floor and machinery space front panel by above-mentioned support and protect driving compartment occupant safety to improve car body rigidity.Simultaneously, welded and installed small rack again in main body framework, its effect is: for fixing, instrument carrier panel being installed and being ensured its intensity, for fixing, support steering column assembly and ensureing the Rigidity and strength of steering shaft, for wire harness is by buckle attachment point is provided, locating point is installed and is ensured to install rigidity for the electric elements such as CD player, TCU, ECU, PAB provide.Existing steering support assembly skeleton through punching press, be welded, relate to operation many, technological process is long, production efficiency is low, welding quality is unstable, and these parts are all steel parts, make steering support assembly skeleton Heavy Weight, and damping property is poor.
Summary of the invention
The purpose of this utility model is to provide a kind of automobile steering supporting assembly skeleton, long to solve the technological process of steering support assembly Skeleton assembly, the problem of damping property and poor dimensional stability.
Automobile steering supporting assembly skeleton described in the utility model, comprise crossbeam, left-side connection bracket, right side wall connection bracket, front panel connection bracket, lower floor connection bracket and installation small rack, described crossbeam, left-side connection bracket, right side wall connection bracket, front panel connection bracket, lower floor connection bracket and installation small rack are the single piece that adopts the moulding of magnesium alloy integrated die-casting, the cross-sectional plane of crossbeam is U-shaped, its stage casing is with respect to left section of crossbeam and right section of sinking 0.2mm～0.5mm of crossbeam, between the both sides that crossbeam stage casing and crossbeam are left section, be connected with continuous V-type reinforced rib, between the both sides that crossbeam is right section, be connected with continuous X-type reinforced rib.Crossbeam cross-sectional plane is U-shaped is convenient to the demoulding, intensity is high, and can reduce skeleton weight, and V-type reinforced rib and X-type reinforced rib have further increased the intensity of whole skeleton, have promoted skeleton Modal Performances, and while preventing automobile shake, instrument carrier panel produces abnormal sound.
Further, the height of described V-type reinforced rib is 40%～60% of left section of both sides height of crossbeam, and the height of described X-type reinforced rib is 80%～95% of right section of both sides height of crossbeam.
Further, the lower end of described lower floor connection bracket is provided with the mounting hole being square, and directly withdrawing pattern casts out, and avoids mechanical processing technique.
Further, between the car body lap plate of described left-side connection bracket and right side wall connection bracket and gusset plate, be provided with triangle reinforced rib, to strengthen the local strength of bearing position, while preventing automobile shake, instrument carrier panel produces abnormal sound.
Automobile steering supporting assembly skeleton described in the utility model, utilize the feature that magnesium alloy materials proportion is little, intensity is high, damping performance good, extrusion process is ripe, the diecasting that steering support assembly frame design is structure as a whole, only need one extrusion process to get final product machine-shaping, no longer need punching press, welding process, reduce technological process, avoided accumulated error, improved dimensional stability and production efficiency.Meanwhile, adopt optimizing structure of above-mentioned reinforced rib, under the prerequisite of intensity that has met automobile steering supporting assembly skeleton, reduced again the weight of automobile steering supporting assembly skeleton, improved automotive energy-saving emission-reducing performance.
