Road safety is composed of many factors, including the experience of the driver, road surface quality and serviceability of the vehicle. The company Mando produced shock test, which has already served his sentence and published their results.
To understand how the defective shock absorber may affect safety should understand the principle of the shock absorber operation. It consists of a reciprocating piston movement, damper piston through a small opening bypass oil from one chamber to another, converting mechanical energy into heat. In other words, the shock absorbers damp vertical vibrations.
Imagine that a shock absorber in the suspension is not in use, than driving on rough road, wheel will bounce and curled spring will return him to the ground, which after impact will bounce back because there is nothing to calm the vibrations. Thus, after overcoming the pits wheel will be jump in a long time and throughout this period, traction with road will be minimal.
