as suspension components such as shock absorbers and damping systems for cars, trucks, motorcycles and rail vehicles. Examples products: Nivomat (a portmanteau of the French niveau and automatique) is the name for a vehicle suspension level-control technology previously created by Mannesmann-Sachs (now ZF Sachs). Compared to the common use of springs, struts, and shock absorbers in a car suspension, Nivomat replaces all of these components with a single unit per wheel which provides damping, ride control, and a self-levelling function. The Nivomat system uniquely incorporates an internal pump which relies on relative movement between the axle and the chassis to provide the levelling and damping function. Sachs-Motors Fichtel & Sachs began producing a vehicle engine with a displacement of 74 cubic centimeters in 1930. As early as 1932, followed by a model with 98 cubic centimeters. In the 1930s, the bike with auxiliary motor "Saxonette", stationary and boat engines and motorcycle engines were included in the program. After the war, the old engine range was supplemented by a large number of new designs with 50 cubic centimeter displacement for mopeds, mopeds, small and light motorcycles. Engines with larger displacement were used in small and snowmobiles and motorcycles. The stationary engine area was expanded by two-stroke diesel engines and mower engines with different capacities. Of particular note is the development of a range of Wankel engines in various sizes for a wide variety of applications. After the assumption of the enterprise by Mannesmann the engine production was stopped 1997. Bicycle components Fichtel & Sachs produced its own bicycle component groups until the takeover of the bicycle division by SRAM in the mid-1990s. For brake production Sachs cooperated with Modolo and in the production of derailleurs with Weinmann and Simplex. Renak in Reichenbach In 1944, the production of the torpedo freewheel hub was outsourced from Schweinfurt to Reichenbach in the Vogtland. At the end of the war, production was interrupted. In August 1945, the operation was taken over by the state government of Saxony and handed over to the USSR on November 1, 1946, trading as part as Awtowelo. On 1 May 1952 it became the VEB vehicle parts factory Fichtel & Sachs, Reichenbach the GDR. In 1956, the Renak brand was protected for the VEB Renak works (Reichenbacher hubs and coupling plants). The mid-1960s, the production of bicycle parts reached a peak with exports to 40 countries, but it was throttled
