Formula 1 high-tech shock absorber from ZF SACHS03.04.2017
In addition to Formula 1 teams such as the Scuderia Ferrari, Scuderia Toro Rosso or Sahara Force India, the BMW Sauber F1 Team also relies on high-tech shock absorbers and Formula 1 carbon clutches from ZF SACHS.
Providing technical support to Formula 1 teams is a long-standing tradition at ZF SACHS. As early as 1937, the first Mercedes Silver Arrows were driven with clutches and ribbed shock absorbers from SACHS. In addition to nine world championship titles in the F1 Constructors' Championship, eight of which were won by Michael Schumacher and Ferrari alone, the teams equipped by ZF SACHS were able to win more than 130 races in Formula 1.
Operating principle of the SACHS F1 shock absorbers.
The innovative SACHS rotational shock absorber technology is used on the rear axle of the Formula 1 vehicles. This revolutionary shock absorber concept was developed in cooperation with Scuderia Ferrari engineers and used for the first time in the Ferrari F2003-GA.
The interesting thing here is that the components act simultaneously as shock absorbers and reversing levers for the pushrod struts, which are supported on the springs. Two conventional shock absorbers are replaced here: Instead of the usual three conventional shock absorbers on the rear axle, the main work is done by two rotational shock absorbers, which are integrated into the reversing lever.
There are numerous advantages to the SACHS rotational shock absorber: first and foremost, of course, the savings in weight and space due to the omission of the traditional shock absorbers. The shock absorbers and reversing levers are combined in a single component.- This allows a more compact gearbox and more efficient aerodynamics of the vehicle. In addition, it was possible to reduce the overall friction of the shock absorber system by eliminating moving parts. - This has a positive effect on the throttle response and driving behaviour of the vehicle.
