By means of visual inspection, a general perspective can be acquired, which must be completed with clearance detector, which will check, as the case may be, the condition and, the fixation of the different components of the suspension as springs (springs, springs ) and although there is not much variety in Guatemala, it can be supplemented with a suspension test machine, which diagnoses buffers, shock absorbers, torsion bars and stabilizers, joints, braces, arms and ball joints that the vehicle incorporates.
We must pay special attention to the state of the fixings to the chassis and clearances, presence of cracks, existence of repairs by welding, presence of damages or deformations, symptoms of corrosion, wear or excessive play, condition of the shock absorbers visually by oil leaks and state of rubber gaskets, bushings, clamps.
add pneumatic suspension of car systems
The existence of air losses in an audible and improper way inside the compressed air supply circuit or the pneumatic bellows.
incorporate pneumatic oil suspension of a car systems
The existence of oil leaks and presence of visible damage.
ANALYSIS OF TIRES AS PHYSICAL EVIDENCE
The study of the traces left by the tires of the vehicles involved in an accident is an important point and not necessarily feasible for the determination of failures in the suspension, which is a system involved with the factor of vehicle safety and not only with the factor comfort or comfort of handling.
Therefore, it is especially important to reflect, in the data collection, all the possible information, identifying the wheel to which each footprint corresponds, their lengths and trajectories. Initially, it could be said that there are as many types of tracks as there are tires involved in an accident, which would indicate that several factors have to be analyzed in order to carry out a complete study. Which provides a wide classification, being able to be imprecise and sometimes incomplete, within the possible marks that can leave a tire on a surface.
Samples of dynamic imbalance can be caused to a mass imbalance, concentrated in asymmetric points with respect to the vertical axis. It occurs in a hesitant movement with which abnormal stresses appear on bearings and suspension and steering elements and tire wear on the edges. It is detected by vibration of the steering wheel, which increases with speed and can cause safety problems, therefore the importance of visual inspection of the tire and be evaluating the possibility of aligning and balancing the tires of your vehicle.
