Abstract
The utility model relates to a back torsion beam of interior high -pressure formed tube spare, a serial communication port, back torsion beam includes crossbeam, longitudinal wall, the setting of longitudinal wall symmetry is in the both sides of crossbeam, wholly be' the U' type, the one end of longitudinal wall is provided with the bush, face bonding wheel hub flange on the other end, one side of longitudinal wall still is provided with shock absorber support. This technical scheme compact structure, high -pressure formed tube spare in main atress spare crossbeam and longitudinal wall are all used has reduced punching press plate and welding piece, and welding seam quantity reduces by a wide margin, has reduced because of the risk that the welding seam ftractureed and results in back torsion beam to lose efficacy, has also strengthened the intensity and the tired durability of product.
Description
Technical field
This utility model relates to torsion beam after one, is specifically related to the rear torsion beam of a kind of inner high voltage moulding pipe, belongs to structural partsof automobiles technical field.
Background technology
Rear torsion beam, belongs to running car system parts, is the one of automobile rear suspension arrangement type, mainly bearing automobile rear load, the bob of balance left and right rear wheel, to reduce rocking of vehicle, keeps the steady of vehicle.In car load assembling is arranged, the bushing locations of rear torsion beam is assemblied on vehicle body, and the brake mounting bracket part of rear torsion beam is installed with rear brake and tire and is connected, and is connected to damping spring at the trailing arm of rear torsion beam.Rear torsion beam is as the back axle of passenger car, need to meet the kinetic characteristic of car load and requirement of strength, belong to key safety part, when automobile travels on the road surface that road conditions are poor, rear torsion beam can make upper and lower twisting actions along with the bob of rear wheel, and the service life of rear torsion beam is had huge test.In prior art, the crossbeam of rear torsion beam and trailing arm mostly are punching press plate and butt welding piece, and loose mail quantity is many, and weld seam is many, and then the failure mode of torsion beam mostly is again weld cracking, and the most more weld seam brings bigger security risk to product；Therefore, exigence one scheme solves above-mentioned technical problem.
Summary of the invention
This utility model is just for technical problem present in prior art, the rear torsion beam of a kind of inner high voltage moulding pipe is provided, this technical scheme compact conformation, main stressed member crossbeam and trailing arm all use inner high voltage moulding pipe, decrease punching press plate and butt welding piece, weld seam quantity is greatly decreased, and reduces the risk causing rear torsion beam to lose efficacy because of weld cracking, also enhances intensity and the fatigue durability of product.
To achieve these goals, the technical solution of the utility model is as follows, a kind of rear torsion beam of inner high voltage moulding pipe, it is characterized in that, described rear torsion beam includes crossbeam, trailing arm, the both sides being arranged on crossbeam that described trailing arm is symmetrical, overall in " U " type, one end of described trailing arm is provided with lining, welds wheelboss flange above the other end, and the side of described trailing arm is additionally provided with shock absorber support.Rear torsion beam in this technical scheme is left and right symmetrical part, and two trailing arms are connected with crossbeam both ends of the surface by welding, improve the safety of rear torsion beam.
As a kind of improvement of the present utility model, described rear torsion beam also includes that spring pedestal, described spring pedestal pass through MAG arc welding with trailing arm and crossbeam, further increase rigidity and the intensity of product.
As a kind of improvement of the present utility model, it is additionally provided with fixed support on described crossbeam, described crossbeam, trailing arm all use inner high voltage moulding pipe, decrease punching press plate and butt welding piece, weld seam quantity is greatly decreased, reduce the risk causing because of weld cracking rear torsion beam to lose efficacy, also enhance intensity and the fatigue durability of product.
Relative to prior art, this utility model has the advantage that, 1) this technical scheme global design is ingenious, compact conformation, 2) this technical scheme ensure that the cooling effect of equipment, improves the service life of the cooling effectiveness of equipment, extension device；3) this technical scheme cost is relatively low, it is simple to further popularization and application；4) this technical scheme uses Lightweight Technology, advantageously reduces complete-vehicle oil consumption.
