Description

A kind of subframe mount structure
Technical field
This utility model is related to auto Body Technology field, specifically a kind of subframe mount structure.
Background technology
As auto industry is developed rapidly with scientific and technological, to performance requirements such as the intensity of vehicle body, rigidity, mode also increasingly High.Skeleton of the subframe as front axle, supporting front axle, even suspension, electromotor make vehicle bridge, suspension, electromotor pass through which It is connected with vehicle body, vibration and noise can be intercepted, reduces noise and be vibrated into in-car, lift car load NVH performances.And as car The mounting structure of subframe, requires to its intensity, rigidity, mode, assembly precision very high with it.
Subframe mounting bracket is generally box-shaped structure of the lamina with nut at present, and this structural strength, dynamic stiffness are poor, holds The transmission of construct noise and vibration is easily caused, the comfortableness of in-car member is affected, simultaneously as subframe is in vehicle travel process In there is alternating force, be easily caused this structure crack of vehicle body and bolt torsion decay.
Mounting structure of a kind of automobile accessory frame in engine nacelle curb girder front part disclosed in 104176126 A of CN, which includes Engine nacelle curb girder front part, subframe are installed corrugated tubing, subframe and install nutplate and corrugated tubing reinforcing plate.Subframe installs spiral shell Stricture of vagina pipe, subframe install nutplate and three parts two of corrugated tubing reinforcing plate two interconnected, be mutually corner, be welded on jointly plus In strong part, all formation booster action of X, Y, Z-direction in vehicle body can prevent the torsion of subframe mounting surface when car load runs Turn, it is to avoid subframe installation bolt torsion is decayed.Although the program can be decayed with bolt torsion, its intercept noise, vibration Effect is not ideal enough, affects the comfortable sexual experience of in-car member.
Utility model content
The purpose of this utility model is to provide a kind of subframe mount structure, and which can solve the problem that subframe is run in car load When construct noise and vibration problem of transmission.
The technical scheme that this utility model is taken:
A kind of subframe mount structure, it include mounting bracket before engine nacelle curb girder front part and subframe, enging cabin The opening of curb girder front part is connected on engine nacelle curb girder outside plate, is welded with for auxiliary connection car before subframe in mounting bracket The subframe corrugated tubing of frame.Mounting bracket is located at outside engine nacelle curb girder front part before subframe side and have between the two one secondary Before vehicle frame, reinforcing plate used as interval, before subframe, pasted with the top of engine nacelle curb girder front part by the edge portion one side of reinforcing plate side Chalaza is welded, and another side is fitted with the edge portion of mounting bracket side before subframe spot welding;The side of reinforcing plate opposite side before subframe Along portion with engine nacelle curb girder outside plate towards engine nacelle curb girder front part while fit spot welding, pacify before another side and subframe The edge portion laminating spot welding of dress support opposite side;Subframe corrugated tubing also with subframe before reinforcing plate be welded and fixed.
Further, reinforcing plate, enging cabin side before mounting bracket, subframe before engine nacelle curb girder front part, subframe Beam outside plate is spacing to be located at cavity body structure of the outer lateral section of engine nacelle curb girder front part for " day " font into one.
Further, subframe corrugated tubing is located in described " day " font cavity, and its one end complete cycle is welded in subframe One side of the front mounting bracket just to engine nacelle curb girder front part, its other end before the subframe reinforcing plate and with subframe before Reinforcing plate is also welded for complete cycle.
Further, place face and the pair of plate weld subframe corrugated tubing are strengthened before subframe before mounting bracket, subframe Vehicle frame corrugated tubing is vertical.
This utility model achieves the connection of subframe and engine nacelle curb girder front part, and which passes through overlap edge point and is welded into space Separator cavity structure, on the one hand it has higher intensity, rigidity, can effectively intercept vibration and the transmission of noise, the opposing party Face its adopt corrugated tubing connection subframe before before reinforcing plate and subframe mounting bracket form spatial connection structure, assemble more firm Gu it is reliable, it is to avoid bolt is decayed by torsion after alternating force.
Before subframe before mounting bracket, subframe between reinforcing plate, engine nacelle curb girder front part, engine nacelle curb girder outside plate " day " font cavity, intensity, rigidity is high, can effectively intercept vibration and the transmission of noise.Subframe corrugated tubing and secondary car Before frame, before mounting bracket, subframe, reinforcing plate is welded using protection weldering border, it is easy to operated, solid and reliable;In addition between three Vertical relation, beneficial to intercept vibration and noise transmission.
Description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is scatter graph of the present utility model;
Fig. 3 is the sectional view of this utility model " day " font cavity body structure.
Wherein:Reinforcing plate before 1- subframes;2- subframe corrugated tubings;Mounting bracket before 3- subframes;4- enging cabins side Beam leading portion;5- engine nacelle curb girder outside plates.
Specific embodiment
The utility model will be further described with reference to the accompanying drawings and examples.
This utility model is related to following part:Reinforcing plate 1, subframe before subframe shown in respectively Fig. 1 and Fig. 2 Mounting bracket 3, engine nacelle curb girder front part 4, engine nacelle curb girder outside plate 5 before corrugated tubing 2, subframe.Before engine nacelle curb girder The opening of section 4 is connected on engine nacelle curb girder outside plate 5, and before subframe, welding subframe corrugated tubing 2 in mounting bracket 3, secondary Vehicle frame corrugated tubing 2 is used for connecting subframe.Before subframe, mounting bracket 3 is located at the side outside engine nacelle curb girder front part 4, both Between have a subframe before reinforcing plate 1 as interval.The edge portion one side of 1 side of reinforcing plate and engine nacelle curb girder before subframe The top laminating spot welding of leading portion 4, another side are fitted with the edge portion of 3 side of mounting bracket before subframe spot welding.Add before subframe The edge portion of strong 1 opposite side of plate with engine nacelle curb girder outside plate 5 towards engine nacelle curb girder front part 4 while fit spot welding, Another side is fitted with the edge portion of 3 opposite side of mounting bracket before subframe spot welding.Spacing being located at into one of point postwelding is started " day " font cavity body structure on the outside of cabin curb girder front part 4.
Positioned by fixture, it is ensured that before subframe corrugated tubing 2 and subframe, mounting bracket 3 is used for welding subframe corrugated tubing 2 mounting surface laminating, and be welded and fixed in mounting surface joint place complete cycle, as shown in figure 3, the mounting surface is installation before subframe Medial surface of the frame 3 relative to reinforcing plate before subframe 1.Subframe corrugated tubing 2 is equally adopted whole through reinforcing plate 1 before subframe Week is welded and fixed.Before ensureing subframe, before mounting bracket 3, subframe, reinforcing plate 1 welds place face and the pair of subframe corrugated tubing 2 Vehicle frame corrugated tubing 2 is vertical.
