    THE HISTORY

    Right from the outset automotive engineers of the time realised the importance of suspension control and this was important to the handling of the car and that was as far back as 1900, nearly 115 years ago.

    The first example was the multi layered friction type, designed by Hartford & Truffault. They were firstly fitted to an Oldsmobile. The unit depicted in the diagram was very up market, as it was adjustable from inside the car by the driver.

    This type was not that efficient, but it was functional for the era. As the cars became more refined and faster, they realised that a more effective unit was required and thats when they started to develop the shock absorber using hydraulic oil as the main source of control and lever shock absorbers were developed.

    The lever type had an effective bump and rebound stroke controlled by two pistons travelling back and forth in the cylinders. The lever was connected to a bell crank which oscillated when the lever went up and down with the suspension movement. The hydraulic oil was displaced by the piston movement and would be forced through the control valve situated in the body.

    After years of development we have now ended up with the telescopic shock absorber, which is in use to this present and will be around for a few years yet. The two telescopic shock absorbers shown are of two different designs, one being a Twin Tube and the other a Mono Tube.

    All mono tube shock absorbers are nitrogen gas pressurised, but not all twin tube types are, but they both require hydraulic oil to operate.

    There are advantages for both type of designs.

    SHOCK ABSORBERS, THEIR FUNCTION

    The function of a shock absorber is widely misunderstood,. In this issue of the No Bull News we present the bare facts of their operation and what options are available to you when selecting a Pedders shock absorber for your customers requirements.

    The first thing about a shock absorber, is that the name of this component is a misnomer, as the shock absorber does not absorb road shocks. They are a device that control the oscillations of the suspension movement and reduce body roll.

    All shock absorbers fitted to mass production cars contain hydraulic oil, some are gas pressurised and some have a cellular foam membrane fitted.

    SHOCK ABSORBERS IN ACTION

    When the wheel of the car travels over an undulating road surface or when it strikes a bump, the wheel moves in an upward direction and the spring compresses and absorbs the impact. When the spring releases the energy, there is a need to control this movement and this is where the shock absorber comes into its own.

    Movement in the suspension of a car is vital for many reasons, Safety, road holding, comfort and stability. When the shock absorbers are in proper working condition, they assist in keeping the foot print of the tyre in contact with the road to maximise the tractability of the car. Remembering that the average foot print of a tyre is about the size of a No 10 shoe, so the car needs all the assistance available to remain in a controlled situation for the driver in all conditions.
