Description
Technical field
The utility model relates to the automotive suspension field, especially relates to a kind of automobile trailing arm assembly.
Background technology
At present, in the prior art, it as the patent No. 200420021139.6 back trailing arm assembly, its main structure is: bend loss and the straight length that is located at the rear portion by the front portion are formed, and also comprise back trailing arm support, back sprung shock-strut support, axle head connecting panel, back upper suspension arm support, back lower controlling arm support, lining sleeve pipe and lining; Back trailing arm support is connected to the relative both sides of the straight length of trailing arm afterwards with back sprung shock-strut support, the axle head connecting panel is connected the opposite side of back trailing arm support, back upper suspension arm support and back lower controlling arm support are separately positioned on the axle head connecting panel, the lining sleeve pipe is connected the forefront of the bend loss of back trailing arm, and lining is arranged in the lining sleeve pipe.We can realize static wheel alignment parameter by this technology, it is guaranteed by the outerplanar metalworking of axle head connecting panel, avoided the traditional difficulty of swing arm body in design, manufacturing and processing effectively, it is thick and heavy that but its shortcoming is a complex structure, make the variation of state of kinematic motion wheel alignment parameter, be dynamic motion how much, can not get controlling preferably.
Three connecting rod rear-suspension systems this as crossing constrained system, fitness for purpose trailing arm and the prenex adjusting lever unnecessary degree of freedom in the delivery system of working in coordination.In the real work, trailing arm bears moment of flexure and moment of torsion simultaneously in wheel bounce and turning process, have no alternative but the trailing arm design-calculated too complicated thick and heavyly in limited arrangement space for satisfying safety requirements, so that its miopragia even forfeiture originally finally has a strong impact on the steady and comfort property of vehicle behaviour.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of automotive suspension trailing arm assembly at problems of the prior art, its objective is by in limited space, optimizing the trailing arm structure, simplification, intensity height, flexible good to realize its structure finally obtain how much of rational suspension motions and flexibility and match.
The technical solution of the utility model is that this kind automotive suspension trailing arm assembly comprises the wide end of an end narrow " V " type trailing arm body, an end narrower on the trailing arm body is provided with circular hole, welded casing is welded on the circular hole by the mode of circumferential weld weldering, promptly with trailing arm body weld together, an end of broad is provided with the through hole that is used for hold-down bolt on the trailing arm body, and the middle part edge of trailing arm body is provided with the flange that adopts slick and sly receipts limit to handle.
Described trailing arm body knee is provided with reinforced rib.
Be pressed with the hollow rubber bush Assembly in the described welded casing, the trailing arm assembly of being made up of trailing arm body and welded casing is connected with vehicle body module elasticity with bolt by the mounting hole of pipe in the hollow rubber lining.
One end of described trailing arm body broad passes through hole by bolt and steering swivel links together.
A kind of automotive suspension trailing arm assembly with above-mentioned special construction has the following advantages:
1, trailing arm sheet stamping member distribution of stress under various operating modes of the receipts limit processing of local flange in this kind trailing arm assembly edge and slyness is even, the reinforced rib in trailing arm body knee also makes its three bolts that through hole installation places are installed and obtains good bending flexibilities when improving itself longitudinal rigidity.
2, this kind trailing arm assembly is the sheet stamping process conditions, and precision is controlled well, and productive costs is relatively low.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is an assembling scheme drawing of the present utility model.
In Fig. 1-2,1: the trailing arm body; 2: circular hole; 3: welded casing; 4: through hole; 5: the hollow rubber bush Assembly; 6: the vehicle body module.
The specific embodiment
By the combination of structure shown in Fig. 1-2 as can be known, this kind automotive suspension trailing arm assembly comprises " V " type trailing arm body 1 that the wide end of an end is narrow, an end narrower on the trailing arm body 1 is provided with circular hole 2, welded casing 3 is welded on the circular hole 2 by the mode of circumferential weld weldering, promptly with trailing arm body 1 weld together, an end of broad is provided with the through hole 4 that is used for hold-down bolt on the trailing arm body 1, and the middle part edge of trailing arm body 1 is provided with the flange that adopts slick and sly receipts limit to handle; Trailing arm body 1 knee is provided with reinforced rib; Be pressed with hollow rubber bush Assembly 5 in the welded casing 3, the trailing arm assembly of being made up of trailing arm body 1 and welded casing 2 is connected with vehicle body module elasticity with bolt by the mounting hole of pipe in the hollow rubber lining; One end of trailing arm body 1 broad passes through hole 4 by bolt and links together with steering swivel.
With welded casing 3 and " V " type trailing arm body 1 weld together, the mode of this kind circumferential weld weldering can guarantee weld strength by actv. to the trailing arm assembly, welds easily by the circumferential weld weldering, and welding deformation is little; " V " type trailing arm body 1 adopts beloid, local flange and slick and sly processing mode, body knee of receiving the limit that reinforced rib is set, be equipped with 3 connections simultaneously, thereby material is rationally utilized, and guarantee that it is stressed even in the motion process of suspension, cooperate with hollow rubber bush Assembly 5 simultaneously, make it both have bigger longitudinal rigidity, have very big bending flexibility again simultaneously, with the suspension geometry under the accurate assurance sound attitude state.
The trailing arm assembly links to each other with vehicle body module 6 by the tie bolt in the hollow rubber bush Assembly 5, and the other end is connected by three bolts, nut fastener and steering swivels.Be suspended in the process of motion,, can provide longitudinal rigidity by the anisotropic properties of hollow rubber bush Assembly 5, simultaneously again can be for laterally providing than high camber.Its structure is trailing arm body 1 and welded casing 3 circumferential weld solder togethers, improves weld strength; Hollow rubber bush Assembly 5 is pressed into welded casing 3; The trailing arm assembly links to each other with vehicle body module 6 elasticity with bolt by the mounting hole of pipe in the hollow rubber lining, and the other end is connected by three screw bolt and nut fasteners and steering swivel.This kind scheme can guarantee how much control of suspension motion precisely, and the trailing arm distribution of stress is even under the various operating modes, has both improved its driving safety, can guarantee the steady and traveling comfort demand of behaviour of vehicle again.One end of trailing arm assembly is connected hollow rubber lining (VOID BUSH) by bolt with vehicle body module elasticity, the other end is connected by bolt and nut fastener and steering swivel, be equipped with the local flange sheet member of " V " type implementation structure simultaneously and oversimplify, the intensity height is flexible good.Hollow rubber lining 5 is equipped with trailing arm body 1 and guarantees to have the RECESSION flexibility when vehicle runs into obstacle, and the bending that the end that is connected is good is flexible to guarantee that the effect that is suspended in side force still can guarantee how much of suspension motions accurately in the jump process down and up and down.Beloidly be equipped with the reinforced rib of optimization, local flange is equipped with smooth receipts limit, guarantees that trailing arm assembly distribution of stress in the vehicle operating process is reasonable, bulk material obtains reasonable use simultaneously.
