Specific embodiment
Carry out the various exemplary embodiments of detailed description of the present invention now with reference to attached drawing.It should also be noted that unless in addition having
Body explanation, the positioned opposite of the component otherwise illustrated in these embodiments, numerical expression and the unlimited system of numerical value are of the invention
Range.
Simultaneously, it should be appreciated that for ease of description, the size of various pieces shown in attached drawing is not according to reality
Proportionate relationship draw.
Be to the description only actually of at least one exemplary embodiment below it is illustrative, never as to the present invention
And its application or any restrictions used.
Technology, method and apparatus known to person of ordinary skill in the relevant may be not discussed in detail, but suitable
In the case of, the technology, method and apparatus should be considered as part of specification.
It should also be noted that similar label and letter indicate similar terms in following attached drawing, therefore, once a certain Xiang Yi
It is defined in a attached drawing, then in subsequent attached drawing does not need that it is further discussed.
It please refers to shown in Figure 1A and Figure 1B, is that existing frame and plate type wheel side bracket show with what longitudinal trailing arm welded respectively
It is intended to.The wheel side bracket 110 of existing torsion beam includes board-like and frame, is welded on the rear end of longitudinal trailing arm 120, rear-wheel is determined
Position parameter is guaranteed by the relative position that wheel side bracket 110 is welded with longitudinal trailing arm 120.Due to the wheel side branch of existing torsion beam
Frame 110 is to weld together in the production line with longitudinal trailing arm 120, and taking turns between side bracket 110 and longitudinal trailing arm 120 is that rigidity connects
Connect, the two be formed by wheel alignment parameter be it is fixed, cannot be adjusted.Welding stress and vehicle in production process use
Impact in the process can all lead to the deformation for taking turns 110 relative torque forces beam longitudinal direction trailing arm 120 of side bracket, so as to cause rear wheel positioning ginseng
Number is unqualified.
Therefore, in process of production for guarantee rear wheel positioning parameter, the wheel that torsion beam manufacturer wants input price high
Side bracket end face special processing equipment and professional detection device, high production cost.In addition, vehicle inevitably encounters in use
The impact of various complex road surfaces and big minor accident can all cause torsion beam deformation rear wheel positioning parameter unqualified, to influence vehicle
Handling stability, increase the risk of driving, and the torsion beam more renewed is also required to a high expense.Meanwhile rear-wheel is fixed
The position unqualified speed for also accelerating tyre irregular wear of parameter.
