Abstract

The utility model discloses a car steering supporting assembly which comprises a steering supporting beam, a left side connecting support, a right side connecting support, a front wall plate connecting support and a middle supporting bar. The middle supporting bar comprises an upper support and a lower floor connecting support, the left side connecting support, the right side connecting support, the front wall plate connecting support, the upper support and the steering supporting beam are integrally cast into an integrated part through magnesium alloy, and the upper end of the lower floor connecting support is connected with the lower end of the upper support through bolts. The car steering supporting assembly solves the problems that a steering supporting assembly is long in frame assembling technological process and poor in damping performance and dimension stability, working personnel can conveniently conduct assembling, and meanwhile the modality performance and the qualified rate of the steering supporting assembly are improved.

Description

A kind of sedan steering support assembly
Technical field
The utility model relates to automobile component, relates in particular a kind of sedan steering support assembly.
Background technology
In auto parts and components fitting process, turn to support first and carry out packing with instrument carrier panel, after packing completes, will turn to support together with panel assembly from car door opening in lifting driving compartment, be linked and packed with vehicle body left and right gusset, forearm plate, lower floor centre gangway.
Existing steering support assembly mainly adopts steel structure; as shown in Figure 5; by transverse tube 11, left side connection bracket 12, right side connection bracket 13, lower floor connection bracket 14, forearm plate connection bracket 15, form main body, by above-mentioned support, connect left/right-body, lower floor and machinery space front panel 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 guaranteed its intensity, for fixing, support steering column assembly and guaranteeing the Rigidity and strength of steering shaft, for wire harness is by buckle attachment point is provided, for the electric elements such as CD player, TCU, ECU, PAB provide, locating point is installed and is guaranteed to install rigidity.Existing steering support assembly skeleton through punching press, be welded, relate to operation many, technological process is long, production efficiency is low and welding quality is unstable, and these parts are all steel parts, make steering support assembly skeleton weight heavier, and damping property is poor.
Summary of the invention
The purpose of this utility model is to provide a kind of sedan steering support assembly, it is long that it not only solves the technological process of steering support assembly Skeleton assembly, the problem of damping property and poor dimensional stability, and can facilitate staff to install, promote Modal Performances and the qualification rate of steering support assembly.
Sedan steering support assembly described in the utility model, comprise and turn to supporting traverse, left-side connection bracket, right side wall connection bracket, front panel connection bracket and central stay, described central stay comprises upper bracket and is positioned at the lower floor connection bracket of upper bracket below, described left-side connection bracket, right side wall connection bracket, front panel connection bracket, upper bracket and to turn to supporting traverse be the single piece that adopts the moulding of magnesium alloy integrated die-casting, the upper end of described lower floor connection bracket and the lower end of upper bracket are bolted.
Further, the cross-sectional plane of described lower floor lower end is L-type, on its front and side, all offer the first bolt hole, and be provided with nut at this bolt hole place, the cross-sectional plane of described lower floor connection bracket upper end is the L-type matching with upper bracket lower end cross-sectional plane, positive and on side, offer respectively second bolt hole corresponding with described the first bolt hole position at it, hold-down bolt passes successively the second bolt hole and is connected with nut thread with the first bolt hole.
In fitting process, can first magnesium alloy be turned to support and wire harness, safety air bag, steering shaft, CD player, HVAC, instrument cover plate to carry out packing, after completing again on general assembly line by artificial or the holder of manipulator bracket the panel assembly that minute installs and steering support assembly by body in white before door opening enter into that driving compartment is inner to be assembled with body in white, finally again lower floor connection bracket is connected on steering support assembly and floor centre gangway.
Sedan steering support assembly described in the utility model, 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, reduced technological process, avoid accumulated error, improved dimensional stability and production efficiency.In addition, central stay adopts the structure of sectional type, avoided causing magnesium liquid to fill type difficulty because lower floor connection bracket is long, easily form the problems such as defects of die casting such as oxide inclusion and shrinkage porosite shrinkage cavity, qualification rate and the Modal Performances of product have been improved, promote the intensity of steering support assembly, effectively reduced the risk of instrument carrier panel abnormal sound.Lower floor connection bracket and upper bracket are bolted, lower floor connection bracket can be installed in car, efficiently solve steering support assembly and enter the problem in driving compartment because of the long and difficult the past door opening of lower floor connection bracket, also avoid central stay to touch disconnected risk simultaneously, facilitated assembling.
