Breakaway resistance

The breakaway force is a subcomponent of the driving resistance , he was for the explanation of an effect at start of rail vehicles introduced.

The lack of complete lubrication when starting up - especially with plain bearings where the supporting film has to be built up first - results in increased driving resistance. The breakaway resistance is usually 0.6% to 0.8% and in extreme cases up to 2.0% of the driving resistance.

In the field of mechanical engineering , especially conveyor technology , other causes are also possible. In this way, depressions can form on roads with higher elasticity when the vehicle is stationary.
